Ziann’s weekly earnings were proportional to the number of hours she worked. This table shows the number of hours Susan worked and the amount she earned.
How much money did Ziann earn per hour?

Answers

Answer:

Can't answer.

Step-by-step explanation:

We know that Ziann's earnings were proportional to the hours she worked, but the table shows how much Susan earned, so we don't know how much Ziann earned. We are not told that Ziann and Susan are the same person.

Susan's earnings:

$47.50/(5 hours) = $9.50/hour

According to the table, Susan earned $9.50 per hour.

Answers

Answer:

b. 23

Step-by-step explanation:

Using factor trees

23                              115

∧                                 ∧

1  23                           5  23

So,

23= 23

115= 23

If you circle the common factors in each factor tree, you get 23.

Therefore your answer is B

The greatest common factor of the numbers 23 and 115 will be 23.

What is the greatest common factor?

Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).

The whole numbers are given below.

23 and 115

The factor of the number 23 is given as,

23 = 1 x 23

The factor of the number 115 is given as,

115 = 1 x 5 x 23

The greatest common factor of the numbers 23 and 115 will be 23.

Josh works for a construction company that uses 150 pounds of gravel for each driveway they pour.
He can buy a dump truck load with 30,000 pounds of gravel or a pick-up truck load with 2,500 pounds.
Which amount should he buy so that no gravel is left after all of the driveways are poured and why?
A.


Josh should buy the pick-up truck load because 2,500 ÷ 150 = 16 23. There is enough gravel to
pour 16 driveways with 100 pounds of gravel left. You cannot divide 30,000 ÷ 150 evenly.

A rectangle has an area of 12 square centimeters and a perimeter of 16 centimeters. which of the following couldd be its dimensions?

a. 2 cm and 6 cm
b. 3 cm and 8 cm
c. 1.5 cm and 8 cm

Answers

Answer:

a 2 cm and 6 cm

Step-by-step explanation:

The product of the dimensions must be 12 cm². (All answer choices meet that requirement.)

Opposite sides of a rectangle are the same length, so the sum of the two dimensions must be half the perimeter, 8 cm. The sums of the answer choices are ...

8 cm

7 cm

9.5 cm

13 cm

Only the first answer choice meets the requirement for a perimeter of 16 cm. The dimensions could be 2 cm and 6 cm.

Answer:

A. 2 cm and 6 cm 6*2=12 (area)

(3x2)(−2x4) = 3(−2)x2∙4 = 6x8 can you find whats wrong with this problem

Answers

Answer:

the equal sign

Step-by-step explanation:

The final correct result is:[tex](3x^2)(-2x^4) = -6x^6[/tex]

Given that:

The expression: [tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]

The error is in the second step of the simplification:

[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} \\(3x^2)(-2x^4) = 6x^8[/tex]

[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]

The second step is incorrect. The correct rule for multiplying powers with the same base is to add the exponents, not multiply them.

Here, add the power of x is 2 and 4, that is,

2 + 4 = 6

And multiply the coefficient of x as:

The coefficient of x are 3 and (-2).

So, the multiplication as:

3 × (-2) = -6

The correct simplification should be:

[tex](3x^2)(-2x^4) = 3\times(-2) \times x^{2+4}\\(3x^2)(-2x^4) = -6x^6[/tex]

So, the multiplication as:

3 × (-2) = -6

So, the final correct result is:

[tex](3x^2)(-2x^4) = -6x^6[/tex]

Hence, the error occupied in second step.
