Answer:

Mark earns 12 dollars an hour, and Steven earns 15 dollars.

Mark earned 6*12=72 dollars, and Steven earned 15*5=75 dollars.

Step-by-step explanation:

Let's set Mark's salary as x.

Steven=x+3

Last Friday, Steven earned 5(x+3) dollars, while Mark earned 6x dollars.

We can write the sum of these salaries as:

5(x+3)+6x=147

5x+15+6x=147

11x+15=147

11x=132

x=12

Then, we can substitute x with 12.

Mark earns 12 dollars an hour, and Steven earns 15 dollars.

Mark earned 6*12=72 dollars, and Steven earned 15*5=75 dollars.

Answer: Mark earns 12 dollars an hour, and Steven earns 15 dollars.

Mark earned 6*12=72 dollars, and Steven earned 15*5=75 dollars

Answer:

No, she will go $3.15 above 40.

Step-by-step explanation:

1. Since the tip is 15%, you can either multiply 37.52 by 1.15 or 0.15. In the route of multiplying by 0.15, you need to add it to 37.52. I will multiply by 1.15 to make it easier.

2. 37.52x1.15 = 43.148 or about $43.15 (rounded).

Answer:

n=15

Step-by-step explanation:

Answer:

12 people fit in a van, 5 fit in a car

Step-by-step explanation:

v is people in a van, c is people in a car

5v+2c=70

3v+4c=56

5v+2c=70

2c=70-5v

c=35-2.5v

now use substitution to plug in c

3v+4(35-2.5v)=56

3v+140-10v=56

140-7v=56

-7v=-84

v=12

now we know v, plug it in to find c

5(12)+2c=70

60+2c=70

2c=10

c=5

12 people fit in a van, 5 fit in a car

Answer:

18

Step-by-step explanation:

you do PEMDAS

there is parenthesis

12-6+6 times 2

there is multiplication

12-6+12

then there is subtraction and addition so you have to do it left to right

18

Answer:

18

Step-by-step explanation:

When solving these types of questions, you want to remember PEMDAS. According to PEMDAS, P is parenthesis. (14-8) is in parenthesis. 14-8 is 6.

Now the equation looks like this:

12-6 + (6)2

There are no Exponents in this equation, but there is multiplication. If there are no operations between two integers, that means it is likely to be multiplication. 6 x 2 is 12.

Now the equation looks like this:

12-6+ 12

Even though, according to PEMDAS, Addition is before subtraction, you can do either one from left to right. Even with multplication and division.

Now the equation looks like this:

6+12

Obviously 6+12 is 18. So, 18 is the answer.

The value of cos(M) is determined as Four-fifths (4/5).

The length of the adjacent side of the right triangle is calculated as follows;

adj² = hyp² - opp²

adj² = 25² - 15²

adj² = 400

adj = √400

adj = 20

Value of cos(M)

Cos (M) = adj/hypo

Cos (M) = 20/25

Cos (M) = 4/5

Thus, the value of cos(M) is determined as Four-fifths (4/5).

Answer:

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

[tex]V=a^2\frac{h}{3}[/tex]

So its just:

[tex]8.8^2\frac{12.5}{3} = 322.67 cm^3[/tex]

Then you just multiply the volume by the cost per cubic centimetre:

[tex]322.67cm^3*$0.12=$38.704[/tex]

After just multiply the cost of one by how many you want, which is 6:

[tex]38/704*6=232.32[/tex]

The cost to manufacture 6 paper weight is $232.32

where

b = base

h = height

Therefore,

v =  1 / 3 × 8.8² × 12.5

v = 1 / 3 × 77.44 × 12.5

v = 968 / 3

v = 322.666666667 cm³

1 cm³ = $0.12

322.67 cm³ = ?

cost of a paperweight = 322.67 × 0.12 = $38.72

Therefore,

1 paper weight = $38.72

6 paper weight = ?

cross multiply

cost of 6 paper weight = 6 × 38.72

cost of 6 paper weight = $232.32

The literary device known as repetition is used to emphasize the same concept or idea or to communicate a particular message by repeatedly using it.

Although repetition typically relates to sentences or words, it can also be present in the sounds that words make. There are three different techniques to show repeat with noise. Consonance, harmony, starting, and alliteration are the names of these three literary devices.

The term "as usual" is repeated in this situation to emphasize how nothing exceptional was going on; it was just the block bash as usual. The predictability demonstrates that everyone's attitudes and behaviors were uniform and fairly predictable. That is wanted to predict the neighborhood and how they act in a certain way

Answer:

840 cm³

Step-by-step explanation:

In the figure attached, the prism is shown.

The prism can be divided into two rectangular prisms, one at the top, with dimensions 5 x 4 (= 12 - 8) x 6 cm, and the other one at the bottom with dimensions 15 x 6 x 8 cm.

Area of the first prism: 5*4*6 = 120 cm³

Area of the second prism: 15*6*8 = 720 cm³

Then, the volume of the complete prism is 120 + 720 = 840 cm³

The required total volume of the complete prism is 840 cm³.

We have to determine, The volume of the prism 5cm,12,cm 15cm,6cm 8cm.

According to the question,

The prism can be divided into two rectangular prisms,

First part at the top, with dimensions [tex]= 5 \times 4 \times( 12 - 8) = 5\times 4 \times 6 cm,[/tex]

And the other part one at the bottom with dimensions [tex]= 15 \times 6 \times 8 cm.[/tex]

Area of the first prism: [tex]5\times4\times6 = 120 cm^{3}[/tex]

Area of the second prism: [tex]15\times6\times8 = 720 cm^{3}[/tex]

Then, The Total volume of the complete prism is 120 + 720 = 840 cm³

Hence,  The required total volume of the complete prism is 840 cm³.

Answer:

D

Step-by-step explanation:

Remember that the sum of any 2 sides of a triangle always must be greater than the length of the third side.

A. 9 + 5 = 14  so NO

B. 8 + 5 = 13 which is less than 14 so NO

C. 5 + 5 = 10 which is less than 14 so NO

D. 12 + 5 = 16 which is greater than 14.

12 + 5 > 14

14 + 12 > 5

5 + 14 > 12

It works for all 3. That means the answer is D.

Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.

KE =  0.5 x mv^2

M (mass) = 54kg

V (velocity) = 15m/s^2

Then, we plug the values in.

KE =  0.5 x 54(15^2)

Now, we solve.

KE = 0.5 x 54(225)

KE = 0.5 x 12150

KE = 6075

Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.

Thus, the kinetic energy of the object is 6,075J.
