Answer:

1. B) Figure B.

2. C) Figure C.

3. D) Figure D.

4. C) Figure C.

Step-by-step explanation:

Given: Radius of Circle A= 4

Radius of Circle B= 5

Radius of circle C= 6

Radius of circle D= 7

Now, finding circumference and area of all the circle.

We know, circumference of circle= $2\pi r$

Area of circle= $\pi r^{2}$

Where, r= radius of circle and π = 3.14

First, solving for figure A

Circumference= $2\times 3.14\times 4= 25.12\ cm$

Area= $3.14\times 4^{2} = 50.24\ cm^{2}$

Solving for Figure B

Circumference= $2\times 3.14\times 6= 31.4\ cm$

Area= $3.14\times 5^{2} = 78.5\ cm^{2}$

Solving for Figure C

Circumference= $2\times 3.14\times 6= 37.68\ cm$

Area= $3.14\times 6^{2} = 113.04\ cm^{2}$

Solving for Figure D

Circumference= $2\times 3.14\times 7= 43.96\ cm$

Area= $3.14\times 7^{2} = 153.86\ cm^{2}$

∴ 1. Answer is Figure B.

2. Answer is figure C.

3. Answer is Figure D

4. Answer is Figure C.

An angle measures 44° less than the measure of its complementary angle. What is the measure of each angle?

ryzh [129]

a+b=90°

a=b+44°

b+44°+b=90°

2b+44°=90°

2b=90°-44°

2b=46°

b=23°

a=23°+44°

a=67°

From the set (33, 15, 12), use substitution to determine which value of x makes the equation true.

zepelin [54]

X=12 because 3 times 12 equals 36. if you divide by 3 on both sides you would be left with that

1. Two thousand dollars is invested at 5.5 percent interest compounded

Dafna11 [192]

Two thousand dollars is invested at 5.5 percent interest compounded

quarterly for 2 years. Then the amount is $ 2230.88

Solution:

Given that Two thousand dollars is invested at 5.5 percent interest compounded quarterly for 2 years

The formula for amount using compounded quarterly is given as:

$\text { Amount }=P\left(1+\frac{R / 4}{100}\right)^{4 T}$

Where, "p" is the principal sum

"R" is the rate of interest

"T" is the number of years

Here in this problem,

P = 2000 ; R = 5.5 ; T = 2 years

Plugging in values in formula we get,

$\text {Amount}=2000\left(1+\frac{\frac{5.5}{4}}{100}\right)^{4 \times 2}$

$=2000\left(1+\frac{1.375}{100}\right)^{8}$

On solving we get,

$=2000(1+0.01375)^{8}=2000(1.11544)=2230.88$

Hence the amount is $ 2230.88
