Answer:

C. 51.84 cm³

Step-by-step explanation:

Volume of traingular prism = Base Area * height of prism

Base Area = ½*base(b)*height(h)

Where, b = base of traingular base = 5.4 cm

h = height of triangular base = 3.2 cm

Base Area = ½*5.4*3.2 = 8.64 cm²

Height of prism is given as 6 cm

Therefore, volume of triangular prism =

8.64*6 = 51.84 cm³

Volume is C. 51.84 cm³

Answer:

Alice can drive 147 miles

Step-by-step explanation:

At first you subtract $17.95 from $40.

Then you are left with $22.05

Finally, you divide $22.05 by $0.15

And you get 147, so she can drive 147 miles without going over her limit.

Answer:

m=14

n=32

p=64

Step-by-step explanation:

B=M, so 154=11m

m=154/11

m=14

E=P, so 118=n+86

n=118-86

n=32

A=L, so 116=180-p

p=180-116

p=64

Answer:

The answer is below

Step-by-step explanation:

a) Natalie basic salary is $300 per week. She is paid a commission of 30% of her total sales for the week. Therefore her total weekly salary per week is given by:

Total weekly salary = Basic salary + Commissions

If Natalie makes $225 in sales, her commission = 30% of $225 = 0.3 × $225 = $67.5

Total weekly salary = Basic salary + Commissions = $300 + $67.5

Total weekly salary = $367.5

b) If Natalie makes $x in sales, her commission = 30% of $x = 0.3 × $x = $0.3x

Total weekly salary = Basic salary + Commissions = $300 + $0.3x

Total weekly salary = $(300 + 0.3x)

Answer:

350 miles

Step-by-step explanation:

Let x represent the miles driven

The cost with the first plan will be represented by 0.40x + 70

The second plan will be represented by 0.60x

Set these 2 expressions equal to each other and solve for x:

0.40x + 70 = 0.60x

70 = 0.20x

350 = x

So, Susan will have to drive 350 miles for the cost to be the same

Answer:

[See Below]

Step-by-step explanation:

✦ First change the improper fractions to decimals:

  ✧ ⁵⁄₄ = 1.25

  ✧ -⁹⁄₅ = -1.8

✦ Then divide:

  ✧ 1.25 ÷ -1.8 = -0.69

So x would be -0.69 in decimal form.

Your answer would 1,548. You would multiply the two numbers, as numbers in parentheses immediately next to each with no symbol of mathematics between them means multiplication, you would just multiply them. Hope this helps!

Step-by-step explanation:

5/(x + 2) + 3/(x - 4) = 2

5(x - 4) + 3(x + 2) = 2(x + 2)(x - 4)

5x - 20 + 3x + 6 = 2x^2 - 4x - 16

8x - 14 = 2x^2 - 4x - 16

4x - 7 = x^2 - 2x - 8

x^2 - 6x - 1 = 0

By using the quadratic formula, x = (-6 +/-√40)/2.

Answer:

-7

Step-by-step explanation:

Since we are losing something, it is reasonably assumptive that we have to have a negative.

So a loss of 7 yards would be an integer of -7.

The values of the given function when x = -3, 0, and 5 are 13, 4, and -11 respectively

From the question,

The given function is g(x) = 4 - 3x

We are to evaluate the function for the given values of x

put the value x = -3 into the function

That is,

g(x) = 4 - 3x becomes

g(-3) = 4 - 3(-3)

g(-3) = 4 + 9

g(-3) = 13

Put the value x = 0 into the function

That is,

g(x) = 4 - 3x becomes

g(0) = 4 - 3(0)

g(0) = 4 - 0

g(0) = 4

Put the value x = 5 into the function

That is,

g(x) = 4 - 3x becomes

g(5) = 4 - 3(5)

g(5) = 4 - 15

g(5) = -11

Hence, the values of the given function when x = -3, 0, and 5 are 13, 4, and -11 respectively

Answer:

Step-by-step explanation:

Given the angles ∠ABF=8s-6, ∠ABE = 2(s + 11), we are to find the angle ∠EBF. The following expression is true for the three angles;

∠ABF = ∠ABE + ∠EBF

Substituting the given angles into the equation to get the unknown;

8s-6 = 2(s + 11)+ ∠EBF

open the parenthesis

8s-6 = 2s + 22+ ∠EBF

∠EBF = 8s-6-2s-22

collect the like terms

∠EBF = 8s-2s-22-6

∠EBF = 6s-28

factor out the common multiple

∠EBF = 2(3s-14)

Hence the measure of angle ∠EBF is 2(3s-14)

Answer:

-15

Step-by-step explanation:

-24-(-9)= -15

On January 3, the high temperature in Anchorage, Alaska, was −24∘F. That same day, the high temperature in Minneapolis, Minnesota, was −9∘F. Since, temperature is of interval scale, the difference between the temperature in Anchorage and the temperature in Minneapolis is of 15 degrees.

There are four scales of measurement. They are : nominal, ordinal, interval and ratio scale. Nominal and ordinal scales are for categorical data. Whereas, interval and ratio scale are for numerical data.

Interval scale only allows arithmetic operation addition and subtraction, but not multiplication and division.

Given in the question,

temperature of Anchorage, Alaska = −24∘F

temperature of Minneapolis, Minnesota =  −9∘F

difference in the two temperature =  −9∘F - ( −24∘F) = -9 + 24 = 15°F

Answer:

5 to the power of 2.

Step-by-step explanation:

Parallel lines have equal slopes, but different y intercepts.

For example, y = 2x+5 and y = 2x+7 are parallel lines with the same slope m = 2, but the y intercepts are different (5 and 7) to ensure we aren't talking about the same line.

Answer: Symmetric property of equality

This is the idea that if x = y, then y = x. We can swap the left and right sides of an equation, and still mean the same thing. The same applies to congruences as well.
