Alja [10]3 years ago
3 0

Answer:

x = 6

y = -9

x = -25

Step-by-step explanation:

<u>1st Equation</u>

Step 1: Write out equation

3(4x - 3) - 19 = 8x - 4

Step 2: Solve

12x - 9 - 19 = 8x - 4

12x - 28 = 8x - 4

4x - 28 = -4

4x = 24

x = 6

<u>2nd Equation</u>

Step 1: Write out equation

-6y + 14 = 32 - 4y

Step 2: Solve

-2y + 14 = 32

-2y = 18

y = -9

<u>3rd Equation</u>

Step 1: Write out equation

-28 + 5 - 3x = 2 - 2x

Step 2: Solve

-23 - 3x = 2 - 2x

-23 = 2 + x

-25 = x

x = -25

7. The largest of the Great Pyramids in Egypt was built with a square base,
strojnjashka [21]

Answer:

Difference between the original and current volumes = 4013140.30 cubic feet

Step-by-step explanation:

Largest pyramid has the square base with one edge = 754 feet

Area of the square base = (Side)²

                            = (754)²

                            = 568516 square feet

Volume of the pyramid = \frac{1}{3}(\text{Area of the base})(\text{Height})

                                       = \frac{1}{3}\times 568516\times 481

                                       = 91152065.3 cubic feet

After erosion,

Area of the base = (745)² = 555025 square feet

Volume of the pyramid = \frac{1}{3}(555025)(471)

                                       = 87138925 cubic feet

Difference between the original and current volumes of the pyramid

= 91152065.30 - 87138925

= 4013140.30 cubic feet

The average hourly charge of plumbers in the Denver area is $84.00 with a standard deviation of $4.00. Assume that the hourly ch
Simora [160]

Answer:

The probability is 0.31

Step-by-step explanation:

In this question, we are tasked with calculating the probability that a random plumber called at Denver will charge an amount greater than $86 given the mean and the standard deviation.

Firstly, we calculate the standard score of $86 using the mean and the standard deviation.

Mathematically;

z-score = (x-mean)/SD

where x = 86, mean = 84 and SD = 4

z-score = (86-84)/4 = 2/4 = 0.5

Hence, we want to calculate P(z ≥ 0.5)

Using standard table

P( (z ≥ 0.5) = 1 - P(z ≤ 0.5) = 1 - ( 0.19146 + 0.5) = 0.30854

To the nearest hundredth = 0.31
