Answer:

-3+x/7=-2 is equation, 7 is the answer

Step-by-step explanation:

-3+x/7=-2 add 3 to both sides.

x/7=1 multiply 7 to both sides

x=7 this is the answer

B) 12/13

1) In this triangle, the sine of angle A is given by the opposite leg over the hypotenuse, so we can write it out. Since the hypotenuse is opposite to the right angle:

Note that we simplified that original ratio 36/39 dividing both numerator and denominator by 3

2) Hence, the answer is B) 12/13

To write the equation of the line that passes through (10,80) (5,65)

we will use the formula;

x₁ = 10 y₁ = 80 x₂ = 5 y₂ = 65

substituting the above into the formula;

we will go ahead and simplify

y- 80 = 3(x - 10)

y- 80 = 3x - 30

y -3x -80 + 30 = 0

y - 3x - 50 = 0

The above is the equation of the line.

To write in a slope-intercept form simply means to write it in the form;

y = mx + b

where m is the slope and b is the intercept

Hence;

y = 3x + 50

The above is the equation of the line in a slope-intercept form

Step-by-step explanation:

For rounding off to nearest tens, we compare the last digit.

The constant of proportionality that lies in all of the pairs of values that we have here is given as 17.5

This is the term that is used to refer to the ratio that is known for the fact that it helps to relate two values that are given in a proportional way.

For instance we are to find the constant proportionality of (9, 148.50)

This is given as 9 + 148.5 / 9

= 157.5 / 9

= 17.5

Then the second pair is (15 ,247.50)

In the same way 15 + 247.50 / 15 = 17.5

Hence we can see that the constant of proportionality in all of the pairs is 17.5

In order to solve the system, we can compare both y values from each equation:

So the solution for this system is the pair (0, -4), that is, x = 0 and y = -4.

The equation of the line passing through points  (0,1) and (2,2) will be y = ( 1 / 2) x + 1

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope= 2-1   /   2-0  =  1 /2

Now pick one of the points and put in for y and x use (2,2).

2= 1/2(2) +b

2=1 + b

2-1 =1-1 +b   subtract 1 from each side

1 = b   This is your y-intercept

The equation will be written as:-

y = ( 1 / 2) x + 1

Using the mathematical operations of subtraction and division, Dan needs more than 25 hours to make more than 300 sales calls for this week to achieve the weekly goal.

Subtraction and division operations are two of the basic mathematical operations.

The subtraction operation involves operating on the minuend using the subtrahend to arrive at the difference.

In other words, the difference from a subtraction operation is the minuend minus the subtrahend.

The division operation is then applied to the difference above to arrive at the quotient.

The number of sales calls per hour = 12

The expected sales calls per week > 480

The number of sales calls already made by Juanita = 180

The more hours required to make more than 300, x, is 25 or more hours (480 - 180)/12

Thus, the number of more hours, using mathematical operations, that Juanita needs to reach the weekly sales calls goal is 25 or more hours.

The adjacent angles in a parallelogram are supplementary. This means the sum of the angles is equal to 180 degrees

The adjacent angles in this paralllelogram are (4x + 2)° and 34°

(4x + 2)° + 34° = 180°

4x + 2 + 34 = 180

4x + 36 = 180

4x = 180 - 36

4x = 144

Divide both sides by 4:

4x/4 = 144/4

Since the two cylinders are congruent, it means that their dimensions are exactly the same thing.

In other words, the radius of cylinder 1 is the same as that of cylinder 2, and the height of cylinder 2 is the same as that of cylinder 1. This is what it means for two solid shapes to be congruent.

Now, to find the volume of cylinder 2, we apply the frmula for the volume of a tyical cylnder:

Now,

radius of cylinder 2 = radius of cylinder 1 = 3

height of cylinder 2 = 8

Thus: r = 3, h= 8

Therefore:

Therefore the volume of cylinder 2 is 72pi cubic units (Option D)

Answer:

Equation: 2x +2x +x -8= 4(x +2)

x= 16

Step-by-step explanation:

The perimeter is the total length of the sides of a particular shape or figure.

Given that the triangle and square have an equal perimeter,

Perimeter of triangle= perimeter of square

Since a square has 4 equal sides,

2x +2x +x -8= 4(x +2)

Let's solve the above equation.

Simplify and expand:

5x -8= 4x +8

Move x terms to the left of the equation, constants to the right.

5x -4x= 8 +8

Answer:

x = 16

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

As the sides of a square are equal in length, the perimeter of a square is four times the length of one side.

[tex]\begin{aligned}\implies \textsf{Perimeter of the square}&=4(x+2)\\& = 4x+8\end{aligned}[/tex]

[tex]\begin{aligned}\implies \textsf{Perimeter of the triangle}&=2x+2x+(x-8)\\&=4x+x-8\\&=5x-8\end{aligned}[/tex]

Each Jet Ski should sell for $8288.

What is selling price?

The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.

Let the selling price be x.

Therefore according to the question,

( x - 5600/ 5600) 100 = 48

=>  x - 5600 = 48 . 56
