A scale model of a boat is 6 inches long. The actual boat is 42 feet long. Which statement(s) are true??

Answers

Answer:

B. 1 in = 7 ft

Step-by-step explanation:

Since on the scale the boat was 6 inches and the actual boat was 42 feet, we need to divide to see how many feet correlate to the number on inches on the scale. So we do 42 / 6, which equals 7. This means that for every inch on the scale, it will be 7 feet in real life.

the answer is B. hope this helps

How do you convert 14x + 19y = 20 into slope intercept form?

Answers

Subtract 14x from both sides. Then divide both sides by 19

[tex]14x + 19y = 20\\\\19y = 20-14x\\\\19y = -14x+20\\\\y = \frac{-14x+20}{19}\\\\y = \frac{-14x}{19}+\frac{20}{19}\\\\y = -\frac{14}{19}x+\frac{20}{19}\\\\[/tex]

The equation is now in slope intercept form y = mx+b

m = -14/19 is the slope

b = 20/19 is the y intercept

How do you convert 20x + 9y = 9 into slope intercept form?

Answers

Answer:

[tex] y = - \frac{20}{9} x + 1 [/tex]

Step-by-step explanation:

[tex]20x + 9y = 9 \\ \\ 9y = - 20x + 9 \\ \\ y = - \frac{20}{9} x + \frac{9}{9} \\ \\\purple {y = - \frac{20}{9} x + 1} \\ this \: is \: the \: required \: \\slope \: - intercept \: form \\ \ \\ where \: \\ slope \: = - \frac{20}{9} \\ \\ y - intercept = 1[/tex]

20x+9y=9

First, the formula for slope intercept is y=mx+b
So, in order to get it in the slope form we have to subtract 20x from both sides.
We end up with, 9y=-20x+9
We have to get rid of the 9 so we divide.
9y=-20x+9
/9 /9. /9

Which values for x make this inequality false?

Answers

Answer:

0, -11, -5, and 20

Step-by-step explanation:

The inequality can be read as x is less than -12.8 (or -12.8 is greater than x)

This means that we need to pick x values that are greater than -12.8 for the inequality to be false.

The values greater than -12.8 are:

0, -11, -5, and 20

-5 makes the x value false

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Answers

Answer:

Step-by-step explanation:

1. y = -3/4 +4 cause that is the same line as the equation and since they are the same line it would mean there would be infinitely many solutions.

2. y=-3/4x+2 if you graph this line next to the orginal line it runs through (0,1) and you can see that its paralellel and will never meet the other line so there will be no solutions

3. for this question im confused because none of the answers fits the line that the question is asking for the closest would be y= -3/4x+2 since it runs through (0,2) but other than that none of the answers fit the line its describing.

an equation that would work though would be y=-1/4x+2

Answers

Answer:

See explanation

Step-by-step explanation:

So, the angle for QRS is the interior angle of R. The exterior angle outside of angle R is for the equation you are going to use. Because angle R is on a straight line, the interior angle of R plus the exterior angle of R will equal 180 degrees. From there you should be able to calculate the rest of the angles, I believe you should be able to calculate y first.

All of the angles in a triangle add up to 180. From there you make an equation which would give you the value of y.

We know that the bottom line is straight, so it equals 180*. QRS is supplementary to the R* angle, which is 144*. All supplementary angles add up to 180, so 180-144 would give us 36* for the Value of QRS.

Now we know QRS=36* and the sum of all the angles is 180, we can write the equation
6y + 36 =180
y= 24

Now you plug the y in ... giving you the value of angle S to be 24* and angle Q to be 120.

QRS = 36*
Q= 120

Answers

Answer:

A. 20 ft

Step-by-step explanation:

(120/2)-40=20

Answer:

a) 20 feet

Step-by-step explanation:

We know it's a rectangle so lengths are the same and widths are the same

If length is 40

That would mean 120-2(40) = 80

We know 2 widths of a rectange so 40/2 is 20

Therefore 20 feet.

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4
