18. Ericka bought 5 palettes and 3 paint brushes for $22.40. She could have bought 14 palettes with the same amount of money. If she had bought 5 paint brushes and no palettes, how much more money would she have had to pay?
Step-by-step explanation:
since 14 palette can be bought for $22.40
then one pallet will be bought for $1.6
so 5 pallet = $8
the amount for 3 brushes = $22.40-$8 =$14.4
so the amount for one brush = 14.4/3=4.8
therefore the amount for 5 brushes =$24
therefore Ericka will extra ($24 -22.40)
=$1.6

I NEED A ANSWER FAST : The number of calories Brant consumes per day increased by 30% when he went to college. He was averaging 1,800 calories a day before he left. ABOUT how many calories a day is he consuming at college?
Answer:
2340
Step-by-step explanation:
Based on the given conditions, formulate 1800(1+0.3)
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.

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.
7. Find the sum of 67 tenths and 35 hundredths. Give your answer as a decimal.
Step-by-step explanation:
since the tenth for the 67 is 6
and the hundredth for 35 is 5
then the sum
6/10+5/100
0.6+0.05
= 0.65
Answer:
7.05
Step-by-step explanation:
67 tenths is 6.7
35 hundredths is 0.35
6.7 + 0.35 = 7.05
Which means the answer is 7.05.
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.

8.27 Any quarter has a face value of $0.25. An eccentric collector offers to buy state quarters for 600% of their face value. At that rate, how much will Larry receive for his collection of all 50 state quarters?
Answer:
$7.50
Step-by-step explanation:
First we find what is the value at which the eccentric collector offers to buy the quarters for. We know the value at which they will buy the quarter for is 600% of the face value - which is $0.25.
Now we do some math and find the value at which the person will buy the quarter for is $1.50.
Now we multiply the value by 50 since Larry would be giving 50 quarters.
$1.50*50 = 7.50
So, Larry will receive $7.50 for selling his 50 quarters to the eccentric collector.
Answer:
Larry will get $1.50.
Step-by-step explanation:
Given:
Any quarter has a face value of $0.25. An eccentric collector offers to buy state quarters for 600% of their face value.To find:
How much will Larry receive for his collection of all 50 state quarters.The formula used to calculate percentage is: (value/total value)×100%.
Step 1 of 1
An eccentric collector offers to buy state quarters for 600% of their face value which means [tex]$6 \times 100 \%$[/tex]. Therefore, 600% of a number is the same as 6 times that number.
50 state quarters is 0.25 dollars .
Larry will get [tex]$6 \times 0.25=1.50$[/tex] dollars.

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

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

Only questions C and D need to be answered
Explanation:
C. Perimeter of Trapezium
= sum of all sides
= 8 + 4 + 4 + 6
= 22
D. Area of Trapezium
= 1/2 × (a + b) × height
= 1/2 × (8 + 6) × √15
= 7√15
E. Perimeter of square
= 4(side)
= 4(5)
= 20
F. Area of square
= side × side
= 5 × 5
= 25
I. Answer
The area will be 4 times more than the current area of about 64 units².
side² = 16
side = √16
side = 4
If the side is doubled, new side = 4 × 2 = 8
New Area: 8² = 64 units²
