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
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.

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

400 ducks consume a reservoir of feed in 30 days, how long will it take 500 ducks
Answer:
24 days.
Step-by-step explanation:
First lets look at the facts.
400 ducks can eat a bunch of feed in 30 days.
That means that 200 ducks would take 60 days.
100 ducks would take 120 days.
Now, we must multiply 100 by 5 to get 500, the target amount of ducks, and divide 120 by 5 to get 24. So, 500 ducks can eat a reservoir of feed in 24 days.
Answer:
24 days
Step-by-step explanation:
It is an inverse proportion, the more ducks the less days the food lasts
400 ----- 30
500 ----- X
[tex]x=\frac{(400)(30)}{500} =\frac{12000}{500} =24[/tex]

PLEASE ANSWER ASAP: After moving to a new house the McGraths budgeted $250 for landscaping. On their visit to a local nursery they chose 8 sunflowers priced at $10.95 a piece and 12 roses priced at $11.95 each. By how much did they exceed their budget?
Answer:
They did not exceed their budget.
Step-by-step explanation:
8(10.95) + 12(11.95) = $231
250 - 231 = $19 savings
Answer: They didn't exceed the budget
Step-by-step explanation:
FACTS:
their budget is $250 dollars.
They buy:
8 sunflowers at 10.95 each
12 roses at 11.95 each.
How much did they exceed their budget? (in other words, by how much did they go over their spending limit?)
Step 1: Find the total amount of money spent on sunflowers.
We know they got 8 sunflowers, and each sunflower cost $10.95.
Total on sunflowers= 10.95x8= $87.60
Step 2: Find the total amount spent on roses
12 roses, each one costs 11.95.
total on roses= 11.95x12=$143.40
Step 3: Find how much was spent
143.4+87.6= 231
They didn't exceed their budget. In fact, they were $19 under their spending limit because 250-231= 19. I double checked my answer.

What is Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
total books = 1500
So, cartoons of 10 needed
=1500 / 10
=150 cartoons
and, cartoons of 15 needed
=1500/15
=100 cartoons

7.6.7. Homer began peeling a pile of 44 potatoes at the rate of 3 potatoes per minute. Four minutes later, Christen joined him and peeled at the rate of 5 potatoes per minute. When they finished, how many potatoes had Christen peeled?
Answer:
When they finished, the number of potatoes had Christen peeled is 20 potatoes.
Step-by-step explanation:
Given:
Homer began peeling a pile of 44 potatoes at the rate of 3 potatoes per minute.
Four minutes later, Christen joined him and peeled at the rate of 5 potatoes per minute We have to find the number of potatoes Christen has peeled.
Step 1 of 1
Homer peels 3 potatoes a minute, so in the four minutes he works alone, he peels [tex]$3 \cdot 4=12$[/tex] potatoes.
This leaves 44-12=32 potatoes for them to peel together.
Together, they peel 3+5=8 potatoes per minute, so they need
[tex]$\frac{32 \text { potatoes }}{8 \frac{\text { potatuos }}{\text { minute }}}=4$[/tex]minutes
to peel the rest of the potatoes.
Christen peels 5 potatoes a minute for 4 minutes, so she peels [tex]$5 \cdot 4=20$[/tex] potatoes.
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.
