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.

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.

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]

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.

Step-by-step explanation:

The cartoons of 10 be 150 and cartoons of 15 be 100.

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.

First, 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

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:

To find:

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.

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

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
