Answer:

Given:

I usually walk from home to work. This morning, I walked for 10 minutes until I was halfway to work.

I then realized that I would be late if I kept walking.

I ran the rest of the way. I run twice as fast as I walk.

Find:

The number of minutes in total did it take me to get from home to work

Step-by-step explanation:

Had I kept walking, the second half of my trip would have taken 10 more minutes.

By doubling my speed for the second half of my trip,

I halved the amount of time it took me to finish.

So, the second half of my trip took 5 minutes, for a total trip time of  10+5 = 15 minutes.

The number of minutes in total did it take me to get from home to work is 15 minutes.

Answer:

75 is 75% of 100

Step-by-step explanation:

Simple explanation: Basically 75% is equal to 3/4 so if we find out how much 1/4 of the whole number is we can multiply it by 4 to get the whole number. Since 75 is 3/4 of the whole number we divide it by 3 which gives us 25 so 25 is 1/4 of the whole number. Afterwards we multiply it by 4 to get the whole number since 4/4 is 1 which is a whole.

Answer:

The number of meters Robert will beat Sam is 12 meters.

Step-by-step explanation:

Given:

When Paul crossed the finish line of a 60-meter race, he was ahead of Robert by 10 meters and ahead of Sam by 20 meters. Suppose Robert and Sam continue to race to the finish line without changing their rates of speed.

Find:

the number of meters by which Robert will beat Sam

Step 1 of 1

When Paul finishes, Robert has run 60-10=50 meters and Sam has run 60-20=40 meters.

Therefore, when Robert and Sam run for the same amount of time, Sam covers [tex]$\frac{40}{50}=\frac{4}{5}$[/tex] of the distance that Robert covers. So, while Robert runs the final 10 meters of the race, Sam runs [tex]$\frac{4}{5} \cdot 10=8$[/tex] meters.

This means Robert's lead over Sam increases by 2 more meters, and he beats Sam by 10+2=12 meters.

Answer:

Step-by-step explanation:

LET'S DO THIS!

Total mass of A, B and C = 1.95kg

Mass of A = 700 kg

Mass of B = 4x the mass of c (4 x C) which is 4c

Mass of C = ? ( let's call it C )

700 + 4c + C = 1.95

700 + 5C = 1.95

5C = 1.95 - 700

5C = -698.05

C = -698.05 ÷ 5

therefore B = 4 × -139.61

= 700 + ( -558.44 ) + ( -139.61 )

= 700 - 558.44 -139.61

= 1.95 kg

Which makes us CORRECT ✅.

G=266-42t and S=332-53t are equations to determine the number hours after noon t, when Genesis and Skylar are the same distance from the stadium

Two or more expressions with an Equal sign is called as Equation.

Genesis is 266 miles away from the stadium.

Genesis is driving along the highway at a speed of 42 miles per hour.

Skylar is 332 miles away from the stadium.

Skylar is driving at speed of 53 miles per hour

Let G represent Genesis' distance, in miles, away from the stadium t hours after noon.

Let S represent Skylar's distance, in miles, away from the stadium t hours after noon.

We need to find an equation for each situation, in terms of t, and determine the number hours after noon t when Genesis and Skylar are the same distance from the stadium.

G=266-42t

S=332-53t

266-42t=332-53t

53t-42t=332-266

11t=66

Divide both sides by 11

t=6 hours

Hence, G=266-42t and S=332-53t are equations to determine the number hours after noon t, when Genesis and Skylar are the same distance from the stadium

Answer: $2.81

Step-by-step explanation:

Pencils: 5 * 0.69 = 3.45

Notebooks: 3 * 2.75 = 8.25
pocket dictionary: 5.49

3.45 + 8.25 + 5.49 = 17.19

20 - 17.19 = 2.81

Therefore, she will get $2.81 change back.

Answer: $2.81

Step-by-step explanation:

FACTS:

Rose bought:

5 pencils for $0.69 each

3 notebooks for $2.75 each

1 dictionary for $5.49

Change recieved if she pays with $20=?

Step 1: Find amount of money spent on pencils

5x0.69= $3.45

Step 2: Find amount of money spent on notebooks

3x2.75= $8.25

Step 3: Find total amount spent

3.45+8.25+5.49= $17.19

Step 4: Find how much change received

So now we want to answer: Her total cost was $17.19, but she paid $20. Change received= ?

20-17.19= $2.81

Therefore, she received $2.81 in change.

Answer:

11. c

12. c

Step-by-step explanation:

11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.

Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.

Angle RTS + Angle STU + Angle UTQ = 180 degrees

60 + 45 + Angle UTQ = 180

Angle UTQ = 180 - 105

                   = 75 degrees

12. Using the corresponding angles theorem, x = 45 degrees and y = 35 degrees.

x + y

Answer:

Assuming the buses travel on the same highway, the number of Dallas-bound buses does a Houston-bound bus pass on the highway is 10 buses.

Step-by-step explanation:

Given:

Buses from Dallas to Houston leave every hour on the hour. Buses from Houston to Dallas leave every hour on the half-hour.

The trip from one city to the other takes 5 hours.

Find:

Assuming the buses travel on the same highway, the number of Dallas-bound buses does a Houston-bound bus pass on the highway (not in the station)

Step 1 of 1

We count the number of Dallas-bound buses that a single Houston-bound bus passes.

There are two groups of Dallas-bound buses that we have to consider.

First, there are the buses that were on the way to Dallas at the time the Houston-bound bus leaves Dallas.

Second, there are the buses that leave Houston after the Houston-bound bus starts but before it arrives at Houston.

In order for a bus to be on the way to Dallas when the Houston-bound bus leaves, it must have left Houston less than 5 hours before the Houston-bound bus leaves.

There is one such bus each hour, for a total of 5 buses.

In order for a Dallas-bound bus to leave Houston after the Houston-bound bus leaves but before the Houston-bound bus arrives, the Dallas-bound must leave Houston within 5 hours after the Houston-bound bus leaves.

Again, there is one such bus each hour, for a total of 5 more buses than the Houston-bound bus passes.

Therefore, the Houston-bound bus passes 5+5=10 Dallas-bound buses.

Answer:

1. 180 degrees

2. 4

3. 8π

4. 8:1

5. 12.5 feet

6. 3 revolutions

7. π/2

8. 64π

Step-by-step explanation:

1. For the first question, we are given that there are 120 degrees in 1/3 of a circle. This makes sense because a complete circle makes up 360 degrees (3*(1/3)). Two figure out how many more degrees there are in 5/6 circle, we first need to figure out how many degrees are in 1/6 of a circle and then 5/6 of a circle. If there are 120 degrees in 1/3 of a circle, there are 120/2 or 60 degrees in 1/6 of a circle (1/6 is half of 1/3). If we multiply this by 5 (because 1/5 * 5 = 5/6), we get that 5/6 of a circle is 60*5 or 300 degrees. That being said, the question is asking us how many more degrees there are in 5/6 circle than 1/3. We know that there are 120 degrees in 1/3 of a circle, so we can do 300 - 120 to figure out the answer, which comes out to be 180 degrees.

2. For the second question, we are given that the area of the circle is 4π. We know that the formula for the area of a circle is [tex]\pi r^{2}[/tex], which means the radius squared of the circle given is 4 (divide by π). If we take the square root of 4, we get the radius of our circle to be 2. Now, all we have to do is figure out the diameter. The radius is the distance between a point on the circle and the center. The diameter is just double this distance because it is the distance between one point on a circle and another point on the exact opposite side (the diameter line segment goes through the center). Since the radius is 2, the diameter has to be 4.

3. For the third question, we are given that the radius of a circle is 4 and we need to figure out the circumference (q). We know that the formula for the circumference of a circle is πd, or 2πr (r is the radius). We can plug the known radius into the equation and solve for the circumference. If we plug in r = 4, we get that the circumference (q) is 2(4)(π), or 8π.

4. For the fourth question, we are given that the radius of circle Q is 4 times the size of the diameter of circle R. We know that the diameter of any circle is just double the size of the radius. This means that, if the radius of circle Q is four times the diameter of circle R, the diameter of circle Q is 4(2) or 8 times the size of the diameter of circle R. This can be represented in ratio form as 8:1 (as in, if the diameter of circle R was 1, the diameter of circle Q would be 8, which is 8 times the size).

5. For the fifth question, the distance traveled in one revolution of a circle is the same as the circumference of the circle. You can imagine a circle and a point on it that is touching the ground. The circumference of this circle (the length of the circle) is the same as the distance traveled between the time the point touches the ground to the time it touches the ground again. Please feel free to let me know if this doesn't make sense. I will try to draw it out. Anyway, we are given the diameter of this wheel (4 feet), and we know that the circumference of a circle is π*d, so the circumference, in this case, would be 4π, which is approximately 12.5 feet.

6. For the sixth question, we just need to figure out the circumferences of the two wheels and compare them. If we go back to the fifth question, we know that the distance traveled by a wheel in one rotation is the same as its circumference. Let's say that the radius of the rear wheel is x. This means that the radius of the front wheel is 3x. The circumference of a circle is 2πr, which means the circumference of the front wheel is 6πx and the circumference of the rear wheel is 2πx. The circumference of the front wheel is 3 times the size of the rear wheel's circumference, which means that it will take 3 revolutions of the rear wheel to complete 1 revolution of the front wheel

7. For the seventh question, if AD is a half circle, that means the side of the square that connects A and D is the diameter of the circle. We know that this diameter is 2 because the length of each side of the square is 2. If the diameter is 2, that means the radius of the half-circle is half of that, or 1. The area of a circle is πr^2, so this circle has a radius of π (r^2 is 1). A half-circle has half of the area of a full circle, so the area of this half-circle would be π/2.

8. For question 8, we know that the circumference of circle A is 8π, and the circumference of any circle is 2πr. This means the radius of circle A is half of 8, or 4. We are given that the radius of circle B is twice the radius of circle A, which means the radius of circle B is 8. The area of a circle is πr^2, and r^2 for circle B is 8^2 or 64. Therefore, the area of circle B is 64π.

Step-by-step explanation:

Step-by-step explanation:

since for one muffins we need 20.35 g of flour

then for 700 muffins we need 20.35×700=14245g

14245g= 14.245kg

since she has 10.8kg then she needs extra (14.245-10.8)kg

=3.445kg

The original price was $66.64

Explanation:

The price is reduced by 55% so all the games are sold for 45%.

Let the cost of game be x,

45% × x = $29.99

0.45 × x = $29.99

x = $29.99/0.45

x = $66.644...

x = $66.64 (rounded to nearest cent)

Never say anything is too hard because one day this will be second nature solving these fractions

Answer: 12.5 hours watching TV

Step-by-step explanation:

Step 1: We know this is an "in all" question, so we first need to find the fractions to add up.

Each dot on the graph represents 1 of each fraction. For example, the dot above the "1/4" means that 1/4 hours were spent watching TV, and the 3 dots above the 1 means that he watched TV for 1 hour in a row 3 times, so the total number of hours for 1 would be 3x1, or 1+1+1.

So we have:

1/4

1/2

3/4

3/4

3/4

1

1

1

1 1/4

1 1/4

1 1/4

1 1/4

1 1/2

(again, each dot represents 1 of each)

Step : Convert these to decimals so it's easier to add

1/4--> 0.25

1/2--> 0.5

3/4--> 0.75

3/4--> 0.75

3/4--> 0.75

1--> 1

1--> 1

1--> 1

1 1/4--> 1.25

1 1/4--> 1.25

1 1/4--> 1.25

1 1/4--> 1.25

1 1/2--> 1.5

0.25+0.5+0.75+0.75+0.75+1+1+1+1.25+1.25+1.25+1.25+1.5= 12.5 hours in all

Answer= 12.5 hours
