Exchange:
2.33 kg = 2330 gr
Grams of grapes that are left after giving 800 grams to her brother:
2330 - 800 = 1530 gr
Grams of grapes each sister will get if Doreen shares the remaining equally:
1530 : 2 = 765 gr

Calculate the sum or difference: 1800x1.3
Calculate the product or quotient: 2340
Answer: 2340
Hope this helps!
The number of calories Brant consumes per day increased by 30% when he went to college. Brant is consuming about 2,340 calories per day at college.
To calculate the number of calories Brant is consuming at college, we need to find 30% of his previous calorie intake and then add it to his initial daily consumption.
Calculate the 30% increase:
30% of 1,800 calories = 0.30 * 1,800 calories = 540 calories
Add the increase to his initial calorie intake:
Calories at college = Initial calories + Increase
Calories at college = 1,800 calories + 540 calories = 2,340 calories
Therefore, Brant is consuming about 2,340 calories per day at college.

Calculate the area and perimeter of the circle.
Answer:
Step-by-step explanation:
The area of a circle of radius r is A = (pi)r^2. In this case, r = 2 units, so the area is A = (22/7)(2 units)^2 = 88/7 units^2
The perimeter of a circle of radius r is P = C = circumference = 2(pi)r. In this case, r = 2 units, so the circumference/perimeter is
C = 2(3.14)(2 units) = 2(22/7)(2 units) = (22/7) units
Circle the correct option: A, B, C, or D.

d. 75 is 75% of what number?
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.
Genesis and Skylar are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Genesis is 266 miles away from the stadium and Skylar is 332 miles away from the stadium. Genesis is driving along the highway at a speed of 42 miles per hour and Skylar is driving at speed of 53 miles per hour. Let GG represent Genesis' distance, in miles, away from the stadium t hours after noon. Let SS represent Skylar's distance, in miles, away from the stadium t hours after noon. Write an equation for each situation, in terms of t, and determine the number hours after noon, t,t, when Genesis and Skylar are the same distance from the stadium
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
What is Equation?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

7.5.5. 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. How many minutes total did it take me to get from home to work?
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.

Rose bought 5 pencils for $0.69 each, 3 notebooks for $ 2.75 each, and a pocket dictionary for
$5.49. How much change will she receive from $20?
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.

20. The total mass of three boxes, A, B, and C, is 1.95 kg. The mass of Box A is 700 g. The mass of Box B is 4 times the mass of Box C. What is the mass of Box B in kilograms?
Answer:
Mass of B in Kg = -558.44kgStep-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 )
Adding all together700 + 4c + C = 1.95
Add like terms700 + 5C = 1.95
5C = 1.95 - 700
5C = -698.05
C = -698.05 ÷ 5
C = -139.61To find B now Remember they said B is 4 times the mass of C and C = -139.61therefore B = 4 × -139.61
B = -558.44 kg To check if we are correct, we add the masses of A, B and C to see if it equals their total mass which is 1.95kgUsing your calculator:= 700 + ( -558.44 ) + ( -139.61 )
= 700 - 558.44 -139.61
= 1.95 kg

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

7.66. 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. Assuming the buses travel on the same highway, how many Dallas-bound buses does a Houston-bound bus pass on the highway (not in the station)?
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.

THIS IS VERY IMPORTANT, WORTH 50 POINTS: The Game Stop is having a sale and all games are reduced by 55%. If a game is now $29.99, what was the original price? ROUND YOUR ANSWER TO THE NEAREST CENT.
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)
