Answer 2

2 = 3

2 x 11 = 22
22 - 19 = 3

3 = 14

3 x 11 = 33
33 - 19 = 14

6 = 47

6 x 11 = 66
66 - 19 = 47

10 = 91

10 x 11 = 110

A special machine is used at a construction site to dig holes. A hole is dug to a depth of 4.75 feet when the machine hits rock. The progress slows to 3/5 feet per hour of digging. The depth of the hole must be at least 12 1/2 feet by the end of the day to stay on schedule. What is the minimum amount of time the machine must continue at its present rate to complete the hole on schedule? Select from the drop-down menus to correctly complete the statement.

Answer: 12 h ; 45 m

Step-by-step explanation:

*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.

What we know:

Progress has been made to 4.75Rate of digging is 3/5 mphDepth must be at least 12 1/2We need to find the minimum amount of time the machine works

How to solve:

By setting up an algebraic equation, we can solve this.

Process:

Set up equation 4.75 + 3/5x = 12 1/2Convert 19/4 + 3/5x = 12 1/2

95/20 + 12/20x = 250/20

Subtract -95/20 -95/20

12/20x= 155/20

Isolate x via division /(12/20) /(12/20)+Simplify

x= 12 11/20

Convert 12 h 33 m

Solution: 12 ; 45

The minimum amount of time taken by the machine will be 12 hours and 55 minutes.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.

Convert the mixed fraction number into a decimal number.

12 ¹/₂ feet = 12.5 feet

Let 'x' be the time. Then the equation is given as,

(3/5)x = 12.5 - 4.75

Simplify the equation, then we have

(3/5)x = 12.5 - 4.75

(3/5)x = 7.75

x = 12.9167

x = 12 + 0.9167 x 60

x = 12 hours and 55 minutes

The base measure of time taken by the machine will be 12 hours and 55 minutes.

Do the values in the table represent a proportional relationship?

x 1 2 3 4
y 2.5 5 7.5 10

Select from the drop-down menu to correctly complete the statement.
All of the y-values a constant multiple of the corresponding x-values, so the relationship

Answers

Answer:

yes every values are increasing constantly by 2.5

Answer:

Step-by-step explanation:

Note that for each unit increase in x, y increases by 2.5. The constant of proportionality is therefore 2.5:

y = 2.5x

All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.

Because of demand, concert tickets that normally sell for 89.99 each are marked up 20%, If Mark wishes to purchase 8 tickets, how much will he pay in total?

20 points will be given

Answers

Answer:$863.92

Step-by-step explanation:20% of 89.99 is 18

89.99x8=719.92

18×8=144

719.92+144=

863.92

Answer:

he will pay 864 dollars in total

Step-by-step explanation:

first we have to find 20% of 90 (i just rounded 89.99 to 90).

20% = 1/5, and 1/5 in decimal form is 0.20. (you can find the decimal value by multiplying the numerator and denominator by 10/10 and then simplifying it)

0.20 * 90 is 18, so we then add that to 90 making 108.

next, since Mark is buying 8 tickets, we multiply 108 by 8, giving us 864

What is an expression?

An expression in math is a statement having minimum of two numbers, or variables, or both and an operator connecting them.

Given are expressions we need to determine expressions having values equal to or greater than 13,

So,

5/6 and 3/4 are numbers less than 1 if we multiply any number with them it will decrease its value,

So, the expression 4 x 13 and 10/10 x 13 will be the expressions having values equal to or greater than 13.

Hence the expressions greater or equal to 13 are B and D.

The answer is yes. If you solve both expressions it would be 5m-10.

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?

Answers

Answer:

A, 32

B, 48

Step-by-step explanation:

Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.

Answer:

40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save
