Step-by-step explanation:

Answer:

l = √10 ft

Step-by-step explanation:

Using Pythagorean Theorem, a² + b² = c², where,

a = ½(2) = 1 ft

b = 3 ft

c = l

Plug in the values

1² + 3² = l²

1 + 9 = l²

10 = l²

√10 = l

l = √10 ft

Answer:

the actual distance between the cities is 80 miles

Step-by-step explanation:

The computation of the actual distance between the cities is shown below:

As we know that

1 inch = 10 miles

So for 8 inches it would required 80 miles

i.e.

= 8 × 10

= 80 miles

Hence, the actual distance between the cities is 80 miles

Answer:

[tex]\$2091.3[/tex]

Step-by-step explanation:

Let P denotes initial value of the product, r% is the annual depreciation rate and t denotes time period.

Depreciation (d) = [tex]P(1-\frac{r}{100})^t[/tex]

Put [tex]P=\$2,600,\,r\%=7\%,\,t=3[/tex] years

Therefore,

 [tex]d=P(1-\frac{r}{100})^t\\\\=2600(1-\frac{7}{100})^3 \\\\=2600(\frac{93}{100})^3\\\\=\$2091.3[/tex]

Answer:

80cookies

Step-by-step explanation:

60 / .75 = 80cookies

good luck, i hope this helps :)

Answer:  80 cookies were sold.

Step-by-step explanation:

To solve this, we divide the amount of money they earned by the amount of money each cookie cost. The answer is 80.

Answer:

If you want to split the amount. You can by 5.50 dollars worth of gummy bears and 4.50 dollars worth of chocolate drops.

Gummy bears- 11oz can be purchased

Chocolate drops- 6oz can be purchased

Step-by-step explanation:

Your total will be 10 dollars

Hope that helped

Answer:

$420

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the annual interest rate expressed as a decimal fraction, and t is the number of years.

Here p = $2,000, r = 0.07 and t = 3 yr, and so

i = ($2,000)(0.07)(3) = $420 was the amount of interest earned.

Answer:

[tex]ADC = 70[/tex]

Step-by-step explanation:

Given

[tex]BCA = 50[/tex]

[tex]DCA = 60[/tex]

See attachment for parallelogram and complete question

Required

Find ADC

From the attachment:

[tex]BCD = BCA + DCA[/tex]

[tex]BCD = 50+60[/tex]

[tex]BCD = 110[/tex]

Adjacent angles add up to 180.

So:

[tex]ADC + BCD = 180[/tex]

[tex]ADC = 180-BCD[/tex]

[tex]ADC = 180-110[/tex]

[tex]ADC = 70[/tex]

Answer:

Answer:

10x-3=7x+45 corresponding angle

10x-7x=45+3

3x=48

x=48/3=16

value of x is 16.

Answer:

64 quarts of maple syrup needed

Step-by-step explanation:

There are a total of 2 quarts in a 1 pint. Therefore, since there are a total of 16 tables and each one has 1 pint, then there are a total of 16 pints in the restaurant. If we multiply this by 2 we get the total amount of quarts of maple syrup in all of the tables

16 * 2 = 32 quarts of maple syrup

Since the bottles are only half full we need to multiply this amount by 2 in order to get the total syrup needed to have all of the bottles filled completely.

32 * 2 = 64 quarts of maple syrup needed

Answer:

4 Quarts

Step-by-step explanation:

You need to find how much maple syrup the owner needs to fill the bottles. But first, you need to find how much syrup the bottles hold in all.

There are 16 bottles. Each bottle holds 1 pint of maple syrup. So, the bottles hold a total of 16 pints of syrup.

Now, find how much maple syrup the owner needs. The bottles hold a total of 16 pints of syrup. Because they are half full, divide by 2.

16÷2=8

The owner needs 8 pints of maple syrup, but the problem asks about quarts. So, find how many quarts are equal to 8 pints. There are 2 pints in a quart, so divide by 2.

8÷2=4

The owner needs 4 quarts of maple syrup to fill the bottles.

Answer:

6.00

Step-by-step explanation:

7.50 x 20% = 1.50

7.50 - 1.50 = $6.00

Answer:

Step-by-step explanation:

This quadrilateral is a kite

And the kite as its opposite angles equal

So based on this we can solve for x

[tex]100 + 100 + x + x = 360[/tex]

(360 here is the total sum of interior angke in a quadrilateral)

[tex]200 + 2x = 360 \\ 2x = 360 - 200 \\ 2x = 160 \\ x = \frac{160}{2} \\ x = 80[/tex]

Thisbis your answer hope it helps :))

Answer:

A-(-5) = A+5

it is the answer

Answer:

a-(-5)

Step-by-step explanation:

Since it's originally an addition question but you want to write it as a difference (subtraction) question, you would use double negative signs. Whenever there are two double negatives next to each other, it counteracts and becomes a positive sign, however you still wrote it as a subtraction question.

Hope this helps

Answer:

C is the answer I think...

Answer:

x = 3 and y = 2

Step-by-step explanation:

We can plug in the numbers. 2 x 3 is 6, and 3 x 2 is 6. 6 + 6 is 12. So, x is 3 and y is 2.

Answer:

The mean is 16

Answer:

∠AOB and ∠DOC

Step-by-step explanation:

Here we have that the vertical angles are equal, so we have that the answer is: ∠AOB and ∠DOC

The other three options are not equal angles.

Answer: ∠AOB and ∠DOC

Step-by-step explanation:

Answer: I think the answers below are all correct! :)

Step-by-step explanation: --> (that sign means I simplified the equation)

9-7r=-5 --> (9+5)-7r=0 --> 14-7r=0 --> 14=7r --> r=2

6x-5=4x+9 --> 6x=4x+(9+5) --> 6x=4x+14 --> 6x-4x=14 --> 2x=14 --> x=7

3(2d-1)=7d --> *multiply the parenthesis* 6d-3=7d --> -3=7d-6d -->d=-3

2(p-3)=4(3p+1) --> *multiply the parenthesis* 2p-6=12p+4 --> -10p=10 --> p=-1
