Answer:

The average age would be 45.

Step-by-step explanation:

Answer:

C. 7 * (2 * 2)

Step-by-step explanation:

Figure out the original expression to see the equivalent expression.

(7 * 2) * 2

14 * 2

28

We have to look for an expression that equals 28.

A is (7 + 2) * 2.

(7 + 2) * 2

9 * 2

18

A equals 18, so it's not equivalent to the original expression.

Now B, which is (2 * 2) + 7

(2 * 2) + 7

4 + 7

11

B equals 11, so it is also not equivalent.

Now C; that is 7 * (2 * 2)

7 * 4

28

C equals 28, so that is equivalent. Although we have found our answer, we need to make sure it's right by evaluating D. ((2 * 7) + (2 * 2))

(2 * 7) + (2 * 2)

14 + 4

18

D, like A, equals 18, so it is also incorrect.

C is the only expression that is equivalent to (7 * 2) * 2, so it is the answer.

Answer:

m<1 = 79°

Step-by-step explanation:

12x + 19 + 22x - 9 = 180

add the numbers

34x + 10 =180

minus 10

34x = 170

divide by 34

x = 5

plug 5 into the equation of angle 1

12(5) + 19 =

79

Answer:

3x³

Step-by-step explanation:

Given the expression

12x^5 =(4x^2 )(C)

We are to find the value of C

Rewriting the equation will give;

(4×3)x²•x³ = 4x²C

4x²•3x³ = 4x²C

Divide both sides by 4x²

4x²•3x³/4x² = 4x²C/4x²

3x³= C

Hence the function C is 3x³

Answer:

C

Step-by-step explanation:

Since we care about distance traveled, it doesn't matter if someone goes high or long or whatever -- we just care about the base number. Finding the absolute value of these:

A = 8

B =10

C = 12

D = 7

12 is the highest, C is our answer

Answer:

m>5

Step-by-step explanation:

Answer:

m > 5

m > 5

or

m ∈ 《5 , +∞》

Answer:

65.8° and 114.2°

Step-by-step explanation:

Suplementary angles sum 180°

then:

a + b = 180°   eq 1

a = b - 48.4     eq 2

replacing the value of eq 2 in eq 1:

(b-48.4) + b = 180°

2b - 48.4 = 180°

2b = 180 + 48.4

2b = 228.4

b = 114.2°

from the eq. 1

a = b - 48.4

a = 114.2 - 48.4

a = 65.8°

Check:

114.2° + 65.8° = 180°

Answer:

[tex]Area = 34.2cm^2[/tex]

Step-by-step explanation:

Let the three sides be a, b and c respectively.

Such that:

[tex]a = 8[/tex]

[tex]b = 9[/tex]

[tex]c= 10[/tex]

Required

Determine the area

This is calculated as:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]

Where

[tex]s = \frac{1}{2}(a + b + c)[/tex]

Substitute values for a, b and c

[tex]s = \frac{1}{2}(8 + 9 + 10)[/tex]

[tex]s = \frac{1}{2}(27)[/tex]

[tex]s = 13.5[/tex]

Substitute values for a, b, c and s in

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)[/tex]

[tex]Area = \sqrt{13.5 * (13.5 - 8)* (13.5 - 9)* (13.5 - 10)[/tex]

[tex]Area = \sqrt{13.5 * 5.5* 4.5* 3.5[/tex]

[tex]Area = \sqrt{1169.4375[/tex]

[tex]Area = 34.2[/tex] -- Approximated

Answer:

y= -4/3x+8

Step-by-step explanation:

y=mx+b is the equation for a line

m=slope

b=y-intercept

First, find the slope

The formula for the slope is: y2-y1/x2-x1

8-0/0-6=

8/-6=4/-3

Plug the slope into the equation

y= -4/3x+b

Now find the y-intercept.

To do this, plug in the x and y of a coordinate and solve for b

I will use (0,8)

8= -4/3(0)+b

8=b

Plug the y-intercept into the equation

y= -4/3x+8

y= -4/3x+8 is your equation

Answer:

71/100

Explanation:

As you can see, the decimal ends at the hundredths place, so the fraction is 71/100. Its simple! If the number end at the tenths, hundredths, or thousandths, just take that number and do it like this! 38/1,000

Answer:

4 W

Step-by-step explanation:

Electrical power, P = I²R where I = current and R = resistance.

Given that I = 0.2 A and R = 100 Ω,

P = I²R

P = (0.2 A)² × 100 Ω

P = 0.04 A² × 100 Ω

P = 4 W
