Answer:

343

Step-by-step explanation:

7 x 7 = 49

49 x 7 = 343

The coal mines is 343 feet deep into the Earth's crust are these shafts.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Given that Coal mines have shafts that can be as much as 7³ feet deep.

We need to find about  how many feet deep into the Earth's crust are these shafts.

From the given it is 7³ feet deep.

So let us find the value of 7³

7×7×7

49×7

Forty nine times of seven

343

Three hundred and forty three.

So the coal mines is 343 feet deep into the Earth's crust are these shafts.

Hence, the coal mines is 343 feet deep into the Earth's crust are these shafts.

Answer:

4 tickets for $1

Step-by-step explanation:

I just divided 8 with 2.00 and got 4.

The value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that:

At a school carnival, tickets can be purchased to participate in different activities.

The data are shown in the picture.

From the data:

y ∝ x

Removing the proportional sign:

y = kx

Plug x = 8

y = 2

2 = 8k

k = 1/4

Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

Step-by-step explanation:

Sorry this is late.

The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.

The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.

Setting up the proportion, gives:

8/3 = x/2.

To solve for x,  cross-multiply:

[tex]8 \times 2 = 3 \times x.[/tex]

Simplifying the equation, gives:

16 = 3x.

Next, divide both sides of the equation by 3 to isolate x:

x = 16/3.

Therefore, the value of x is 16/3.

I dunno what you wrote at the top, but I solved the picture

Step-by-step explanation:

Answer:

Slope : -1

Y-intercept : (0,6)

Step-by-step explanation:

Answer:

Slope: -1

y-intercept: 6

Step-by-step explanation:

Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:

[tex]\frac{7-9}{-1-(-3)}[/tex]

[tex]\frac{-2}{-1+3}[/tex]

[tex]\frac{-2}{2}[/tex]

[tex]-1[/tex]

Now we know that the slope is -1, so m = -1.

Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:

1 = -5 + b

b = 6

Now we know that the y-intercept is 6, so b = 6. I hope this helped!

The graph of the equation is attached .

An equation is an expression that shows the relationship between two or more numbers and variables.

The slope-intercept form of the line equation

y= mx + c

where m is the slope

b is the y-intercept

We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation

y=47x .

Now comparing with the slope-intercept form of the line equation;

m = 47

We know that the value of the y-intercept can be determined by setting x = 0

substitute x = 0 in the equation

y = 47(0)

y = 0

Thus, the y-intercept b = 1

Thus,

The slope m = 47

The y-intercept b = 1

The graph of the equation is also attached.

(1,47) (2,94) (3,141)

Hence, the line passes through the origin with the y-intercept 0.

By applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1

Recall:

Therefore, for the equation p ÷ 4.5 = 6.1, which is:

p/4.5 = 6.1

To get the variable p alone, multiply both sides by 4.5

p/4.5 × 4.5 = 6.1 × 4.5

p = 27.45

Therefore, by applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1
