Oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. What was the total average speed. (answer in mph)

Answers

Answer 1

Answer:

46 2/3

Step-by-step explanation:

Divide 90 by 1.5 because:

Average Distance= distance/time

then 120 by 3 for same reason

then u find each

then add 90 with 120 to get 210 then divide by 4.5 to get 46 2/3

Answer 2

Answer:

46.6666667

Step-by-step explanation:

we need to know the TOTAL average speed. To do that, we need to know how to get the speed, which is distance/time. Now we have to substitute. The equation we get is: s= (90+120)/(1.5+3). After solving, you should get s= (210miles)/(4.5hrs). Now all we have to do is divide, which equals 46.6666667.

Hope this helps! (:

the parking garage charges an initial fee of 5$. Then they charge $10.50 per hour parked. You had to pay $68. How many hours did you park

Answers

6 hours.
If you subtract 5 from 68, you'd end up with 63 which then you can divide
63/10.5 = 6

The equation for the given situation is 5+10.50x=68.

Given that, the parking garage charges an initial fee of 5$.

How can we perceive cartesian coordinate plane?

The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.

The cartesian coordinate plane is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is written as; (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

Given

A rectangular garden is 14 feet wide and 48 feet long.
If you stand in one corner of the garden, how many feet
away is the corner diagonally across from you?

Answers

Answer: 50 feet

Step-by-step explanation:

Since it is a rectangle and you in the corner diagonally; you can draw a line diagonally across in the rectangle and you are left with two triangles.

So since its two right-angled triangles

a = 14 feet

b = 48 feet

You need to find c which is the diagonal.

Using the pythagorean theorem which is:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 14^{2} + 48^{2}[/tex]

Square the a and b then add

[tex]c^{2} = 136 + 2304[/tex]

[tex]c^{2} = 2500[/tex]

Now carry over the square on the c and change it to the square root

[tex]c = \sqrt{2500}[/tex]

when you square root

[tex]c = 50[/tex]

therefore it is 50 feet diagonally across

at the beginning of summer, a maintenance crew refills a swimming pool at a city part. the relationship between the time in hours to fill the pool and the amount of water in the pool is proportional.
after 4 hours, the pool holds 5,200 gallons of water. b. the same crew refills a second pool as represented by the graph shown. is the second pool filled at a faster or slower rate than the first pool? explain.

Answers

Step-by-step explanation:

first pool :

in 4 hours the pool gets 5200 gallons.

that means in 1 hour it gets 5200/4 = 1300 gallons.

so, the filing rate is 1300 gallons / hour.

second pool :

we seen on the graph that

in 3 hours the pool gets 10800 gallons.

that means in 1 hour it gets 10800/3 = 3600 gallons.

so, the filing rate is 3600 gallons / hour.

therefore, the second pool fills at a much faster rate than the first pool (3600 gallons vs. 1300 gallons / hour).

If a number in the tenths place is less than or equal to 4 then we round down. Ex: 1.19 would round to 1

Since 8 is in the tenths place we round up. 3.81 would be 4 rounded to the nearest whole number.

A green bottle holds 8 35 ounces of water. A bluebottle holds 8 67 ounces of water. Write an inequality that compares the fractions and explain which bottle holds more.
PLEASE ANSWER THIS ASSSAAAPPP!!

Answers

Answer:

Blue bottle holds more.

Step-by-step explanation:

Given:

Green Bottle = 8 3/5 = 43/5

Blue Bottle = 8 6/7 = 62/7

Now:

we can write 43/45 as;

43/5 x 7/7 = 301/35     (1)

similarly, 62/7 = 62/7 x 5/5 = 310/35   (2)

Comparing both (1) and (2),

301/35 < 310/35

:. (301 < 310)

Hence,

Blue Bottle will hold more.

There were 56 runners to start a race. In the first half of the race, 1/4 of them dropped out. In the second half of the race, 3/7 of the remaining runners dropped out. How many runners finish the race?

Answers

Answer:

24 runners

Step-by-step explanation:

If 1/4 of the runners dropped out, then 1 - 1/4 or 3/4 continued on. 3/4 of 56 or 3/4 *56 is 42 runners left. Then, out of these 42, 3/7 dropped out. This means 1 - 3/7 or 4/7 of the runners remained. This means that 4/7 * 42 or 24 runners finished the race.

Explain the error in Julie’s work in rewriting the radical expression.

Answers

Answer:

The negative numbers do not have square roots. Therefore the question does not have a solution. That is where Julie made a mistake.

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

First, let's take a look at this property:

[tex] \displaystyle \large{ \sqrt{a} \sqrt{b} = \sqrt{ab} }[/tex]

This only works for a and b ≥ 0.

As for a & b < 0 which results in Imaginary Number, we have to convert in 'i' form.

We know that:-

[tex] \displaystyle \large{ i = \sqrt{ - 1} }[/tex]

Thus:

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{3} i \cdot \sqrt{12}i }[/tex]

Then we can multiply 12 & 3 in square root.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36} {i}^{2} }[/tex]

We know that:

[tex] \displaystyle \large{ {i}^{2} = - 1}[/tex]

Convert i^2 to -1

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36}( - 1) } \\ \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - \sqrt{36}}[/tex]

Then evaluate √36 which is 6.

[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - 6}[/tex]

Therefore the answer should be -6.

Conclusion

Julie cannot use the √a√b = √ab property first because a & b both are < 0 and the property applies for a ≥ 0, b ≥ 0.
