Answer:

314 yd²

Step-by-step explanation:

A = πr²

 Use the formula.

A = π(10)²

 Substitute. Use 10 for r.

A ≈ 3.14 × 10²

 Substitute. Use 3.14 for π.

A ≈ 3.14 × 100 Evaluate the power.

A ≈ 314 Multiply.

The area of the circle is about 314 yd².

Hence, the students that brought a lunch box is 28

Answer:

[tex]h = 3544.83km[/tex]

Step-by-step explanation:

Given

[tex]P= 760 - 0.145h[/tex]

Required

Find h when P = 246

Substitute 246 for P

[tex]246= 760 - 0.145h[/tex]

Collect like terms

[tex]246- 760 = - 0.145h[/tex]

[tex]-514= - 0.145h[/tex]

Make h the subject

[tex]h = \frac{-514}{-0.145}[/tex]

[tex]h = 3544.83km[/tex]

Hi have a great day!! This is our answer. If it is wrong, apologies from our side.

Answer:

d.

Brand C, Brand A, Brand B

Step-by-step explanation:

To find the unit price, we divide the price by the number of pounds.

Brand A: $1.48 for 2.5 pounds

Unit price of:

[tex]\frac{1.48}{2.5} = 0.592[/tex]

Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams

907.18/453.59 = 2 pounds

Unit price of:

[tex]\frac{1.3}{2} = 0.65[/tex]

Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces

50/16 = 3.125 pounds

Unit price of:

[tex]\frac{1.55}{3.125} = 0.496[/tex]

From lowest to highest unit price:

C, A and B, so option d.

Answer:

D

Step-by-step explanation:

Unit prices are ratios, so you can add the two prices together and divide by the smaller unit price to get a usable number.

Answer:

50,000 x 0.90 ^ 4 = X

Step-by-step explanation:

Since the value of a car worth $ 50,000 is deprecating half yearly at 10 percent, the correct expression to express its value after 2 years is determined through the following calculation:

50,000 x 0.90 ^ 4 = X

32.805 = X

Thus, after 2 years with a semi-annual depreciation of 10%, the car will be worth $ 32,805.

Answer:

The awnser is 1/16!!!!!!!!!!!!!

Answer:

On day 20, they should both be on page 200

Step-by-step explanation:

I set the 2 equations up:

10d=8d+40 and then subtracted 8d from both sides

2d=40 and then divided both sides by 2

d=20

I then took 20 and multiplied it by 10 for Ashley (200) and then multiplied it by 8 for Carly (160) and added 40 (200)

Answer:1500 grams

Step-by-step explanation:

Given:

The sequence is:

12, 6, 3, ...

To find:

The formula for the nth term of the given sequence.

Solution:

We have,

12, 6, 3, ...

Here, first term is 12.

Clearly, [tex]\dfrac{6}{12}=\dfrac{3}{6}[/tex]. Since the given sequence has a common ratio [tex]r=dfrac{1}{2}[/tex], therefore it is a geometric sequence.

The formula for the nth term of the given sequence is:

[tex]a_n=ar^{n-1}[/tex]

Where, a is the first term and r is the common ratio.

[tex]a_n=12\left(\dfrac{1}{2}\right)^{n-1}[/tex]

Therefore, the formula for the nth term of the given sequence is [tex]a_n=12\left(\dfrac{1}{2}\right)^{n-1}[/tex].
