Add the 3 ratio portions together: 1 + 4 + 7 = 12

Divide total length by 12:

84/12 = 7

Multiply each ratio portion by 7:

1 x 7 = 7

4 x 7 = 28

7 x 7 = 49

The longest piece is 49 cm

Answer:

49cm

Step-by-step explanation:

1x+4x+7x=84

12x=84

X=7

4*7=28

7*7=49

So we can see 49cm is the longest.

Step-by-step explanation:

subtract 5.4 from 9.9 to get the length of the triangle then multiply by 3.3 and 1/2 to get the area of the triangle then add that to the area of the rectangle by multiplying 5.4 by 3.3

4.5 x 3.3 x 1/2 = 7.425

5.4 x 3.3 = 17.82

7.425 + 17.82 = 25.245

Look at the line and wherever the line meets with the miles then find the miles and that's your answer.

If you want to make sure, do "50(mph) * 2(hours)" and it should land on "100"

Step-by-step explanation:

option A is correct

as, point S lies on = -7, 4

and point T lies on = 5, 4

so, diameter is 12 so radius = diameter/2 = 12/2 = 6

and center is - 1 , 4 as the diameter lies on 4 in y axis

The given equation is :

here, 5x is on both sides, so they cancel out. hence value of x can't be determined.

so, the equation have no solution.

correct choice is B.) no solution

5x -2 = -2 + 5x

Add 2 to both sides to get 5x = 5x

Because this is true then any value of x will still make the equation true.

This means there are infinite solutions.

Answer: a) infinite solution

Answer:

(9, 6)

Step-by-step explanation:

add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18

isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9

substitute 9 in x's place in one of the equations: 9 + y = 15

solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6

combine x and y coordinates together: (9, 6)

The equation of the line is x = -7

The points are given as

(-7, -2) and (-7, 8)

See that the x coordinate of both points are the same.

This means that the line equation is a vertical line that passes through x = -7

Hence, the equation of the line is x = -7

Answer:

hello

Step-by-step explanation:

have a great day...

Step-by-step explanation:

use y^2=4px

p is the distance from the vertex to the focus, which is 8 units left

y^2=4(-8)x

y^2=-32x

Use y²=4px  where p is the distance from the vertex to the focus,

p = 8 to the left,

so p = -8

Plug that in:

y² = 4(-8)x

Sole / simplify / multiply:

y² = -32x

The shower head follows a linear function

From the complete question, we understand that:

Each minute, 5 gallons of water are used

This mean that, the possible ordered pairs are:

[tex]\mathbf{(x,y)= \{(1,5),(2,10),(3,15).....\}}[/tex]

When the shower head is used for 0 minutes we have:

[tex]\mathbf{(x,y)= \{(1-1,5-5)\}}[/tex]

[tex]\mathbf{(x,y)= \{(0,0)\}}[/tex]

The ordered pair when the shower head is used for 0 minutes is (0,0)

The location on the graph is called the y-intercept.

Answer: [tex]y = \frac{1}{3}x-2[/tex]

This is the same as writing y = (1/3)x - 2

Slope = 1/3

y intercept = -2

======================================================

Explanation:

We first need to determine the slope

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{-3-3}{-3-15}\\\\m = \frac{-6}{-18}\\\\m = \frac{1}{3}\\\\[/tex]

Then we'll use this value of m, along with (x,y) = (15,3), to determine the y intercept b value.

[tex]y = mx+b\\\\3 = (1/3)(15)+b\\\\3 = 5+b\\\\3 - 5 = b\\\\-2 = b\\\\b = -2[/tex]

You could use the other point (-3,-3) as well

[tex]y = mx+b\\\\-3 = (1/3)(-3)+b\\\\-3 = -1+b\\\\-3 +1 = b\\\\-2 = b\\\\b = -2[/tex]

Either way, we end up with the same y intercept. You don't need to show both sets of steps when computing b. You only need to pick one set  of steps.

Since m = 1/3 and b = -2, we go from y = mx+b to y = (1/3)x - 2 which is the same as writing [tex]y = \frac{1}{3}x-2[/tex]

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 4 / -3 - 15

= 7/18

y = 7/18x + b

4 = 7/18(15) + b
