Answer:

Expression: 48x + 120y & Area = 1,008 square feet

Step-by-step explanation:

12(4x + 10y)

multiple the 12 into 4x + 10y

12 x 4x = 48x

12 x 10y = 120y

48x + 120y

x = 6 ft

y = 4 ft

Substitite in numbers

48x + 120y

48(6) + 120(6)

Multiply

288 + 720

Add

288 + 720 = 1,008 square feet

Answer:

  26.2 in³

Step-by-step explanation:

The formula for the volume of a cone uses the radius of the cone as one of its variables. Here, the diameter is given, so we need to divide it by 2 to find the radius.

  r = d/2 = (5 in)/2 = 2.5 in

The volume is ...

  V = 1/3πr²h

  V = (1/3)π(2.5 in)²(4 in) = 25π/3 in³ ≈ 26.2 in³

The volume of the cone is about 26.2 in³.

Answer:

y -7 = -4(x + 2)   (Answer D)

Step-by-step explanation:

The general point-slope equation is y - k = m(x - h)

If the slope, m, is -4, and the point is (h, k) with h = -2 and k = 7), then we have in this case

y -7 = -4(x + 2)   (Answer D)

Answer:

5,50,500,5000,50000

Step-by-step explanation:

The first term is given

a1 =5

The second term is when n=2

a2 = 10 * a1 = 10 * 5 = 50

The third term is when n=3

a3 = 10 * a2 = 10 * 50 = 500

The fourth term is when n=4

a4 = 10 * a3 = 10 * 500 = 5000

The fifth term is when n=5

a5 = 10 * a4 = 10 * 5000 = 50000

Answer:   x = 30

==========================================================

Explanation:

When adding three angles of any triangle, they always add up to 180

3x+2x+x = 180

6x = 180

x = 180/6

x = 30

This then means,

This triangle is a 30-60-90 triangle.

Answer:

33 cm

Step-by-step explanation:

Perimeter formula = l + l + w + w, or l x w

Just add all the sides whch equals 33

Answer: 5 cm + 7 cm + 9 cm + 12 cm = 33 cm; Perimeter = 33 cm

Step-by-step explanation:

To find the perimeter of a shape, all you need to do is add up the measure of all the sides.

2.)

B. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to support the power company claim that the mean amount of electricity for their residents is more than the national average.

Step-by-step explanation:

1.)

H0 : μ = 10290

H0 : μ > 10290

n = 153, sample mean, xbar = 10586 ; population standard deviation, σ = 2509 ; α = 0.05

Test statistic:

(xbar - μ) ÷ (σ/√(n))

(10586 - 10290) ÷ (2509/√(153))

296 / 202.84062

Test statistic (Z) = 1.46

We obtain the Pvalue :

Decision Region :

Reject H0 ; if Pvalue < α

Pvalue from Z test statistic calculator :

Pvalue = 0.072

Pvalue > α ; Hence, we fail to reject the Null ; there isn't sufficient evidence to support the power company's claim

2.)

H0 : μ = 10290

H0 : μ > 10290

n = 153, sample mean, xbar = 10446 ; population standard deviation, σ = 2509 ; α = 0.02

Test statistic:

(xbar - μ) ÷ (σ/√(n))

(10446 - 10290) ÷ (2509/√(153))

156 / 202.84062

Test statistic (Z) = 0.769

We obtain the Pvalue :

Decision Region :

Reject H0 ; if Pvalue < α

Pvalue from Z test statistic calculator :

Pvalue = 0.221

Pvalue > α ; Hence, we fail to reject the Null ;

B. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to support the power company claim that the mean amount of electricity for their residents is more than the national average.

Answer:

8 27/28 or 251/28

Step-by-step explanation:

Find common denominators then simply add.

Answer:

-10

Step-by-step explanation:

t3 = a1 + (n - 1)*d

t3 = a1 + (3 -1)*d

2 = a1 + 2d

t17 = a1 + (n - 1)*d

-40 = a1 + 16d                Put the first condition underneath and subtract

  2 = a1 + 2d

-42 = 14 d

d = - 3

2 = a1 + 2*(-3)

2 = a1 - 6                      Add 6 to both sides

2 + 6 = a1

a1 = 8

Now you want the 7th term

t7 = a1 + (n - 1)*d

t7 = 8 + (7 - 1)*d

t7 = 8 + 6*(-3)

t7 = 8 - 18

t7 = - 10

Answer:

c=66°

Step-by-step explanation:

a=51°

51+63=114°

180-114°= 66°

Answer:

66

Step-by-step explanation:

a° = 51° (corresponding angles)

a = 51

a° + c° + 63° = 180° (interior angle sum postulate of a triangle)

51° + c° + 63° = 180°

c° + 114° = 180°

c° = 180° - 114°

c° = 66°

c = 66

Answer:

There are 25 possible schedules.

Step-by-step explanation:

The order in which they play soccer is not important(Monday and Tuesday is the same as Tuesday and Monday), and thus the combinations formula is used to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Monday but not Tuesday:

Monday(1) and 2 out of the remaining 7 - 2 = 5. So

[tex]C_{5,2} = \frac{5!}{2!3!} = 10[/tex]

Tuesday but not Monday:

Tuesday(1) and 2 out of the remaining 7 - 2 = 5. So

[tex]C_{5,2} = \frac{5!}{2!3!} = 10[/tex]

Monday and Tuesday:

Monday and Tuesday(1), plus one out of the remaing 5 days. So

[tex]C_{5,1} = \frac{5!}{1!4!} = 5[/tex]

Total:

10 + 10 + 5 = 25

There are 25 possible schedules.

Step-by-step explanation:

See comment for complete question

Given

[tex]P \to Potato[/tex]

[tex]C \to Carrot[/tex]

[tex]3P + 2C = 5.08[/tex]

[tex]P = 1.24[/tex]

Required

[tex]12P + 1\frac{1}{2}C = ??[/tex]

First, we solve for C

Substitute [tex]P = 1.24[/tex] in [tex]3P + 2C = 5.08[/tex]

[tex]3 * 1.24 + 2C = 5.08[/tex]

[tex]3.72 + 2C = 5.08[/tex]

Collect like terms

[tex]2C = 5.08 - 3.72[/tex]

[tex]2C = 1.36[/tex]

Solve for C

[tex]C = \frac{1.36}{2}[/tex]

[tex]C = 0.68[/tex]

So, we have:

[tex]P = 1.24[/tex]

[tex]C = 0.68[/tex]

[tex]12P + 1\frac{1}{2}C = ??[/tex] becomes

[tex]12P + 1\frac{1}{2}C = 12*1.24 + 1\frac{1}{2}*0.68[/tex]

[tex]12P + 1\frac{1}{2}C = 14.88 + 1.02[/tex]

[tex]12P + 1\frac{1}{2}C = 15.90[/tex]
