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

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
Order the steps to solve -3x + 2.4 = 19.2
- Simplify to x = -5.6
- Subtract 2.4 from both sides
- Simplify to -3x = 16.8
- Divide both side by -3
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

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.

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.

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.

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.
