Answer:

y = 1/5x + 2

Step-by-step explanation:

y = - 5x - 4

Slope: -5

Slope of the perpendicular line: 1/5

Point (15,5)

y-intercept: 5 - (1/5)(15)

= 5 - 3 = 2

AfilCa [17]

The information's given in the question are of vital importance. These information's should be very useful while getting to the desired answer of the given question.Let us now concentrate on the problem that needs to be solved.
The height of the sign that casts a shadow of 4 meters is = 5 meters
Then
The height of the tree that casts a shadow of 30 meters = (5/4) * 30 meters
= 150/4 meters
= 37.5 meters
So the tree casting a shadow of 30 meters is actually 37.5 meters in height. I hope the procedure is simple enough for you to understand.

$this \: paper \: needs \: to \: be \: folded \: \\ \underline{ \boxed{twice \: (2 \: times)}}$

Step-by-step explanation:

$let \: the \: let \: the \: length \: be \to \: x \\when \: folded : it \: becomes \to \: \frac{x}{2} \\hence : \to \\ 93.5 \times \frac{x}{2} = (93.5 - 1) \\ 93.5x = 2(93.5 - 1) \\ 93.5x = 2 \times 92.5 \\ 93.5x = 185 \\ x = \frac{185}{93.5} \\ \boxed{x = 1.9786096257 }\\$

Kurt has a collection of 155 United States and Canadian stamps. He has 1.5 times as many United States stamps as Canadian stamps

stealth61 [152]

Kurt has 93 United States stamps in his collection

Step-by-step explanation:

The given is:

Kurt has a collection of 155 United States and Canadian stamps
He has 1.5 times as many United States stamps as Canadian stamps

We need to find how many United States stamps Kurt has in his collection

Assume that kart has x Canadian stamps

∵ kart has x Canadian stamps

∵ He has 1.5 times as many United States stamps as Canadian stamps

- That means the number of United States stamps is 1.5 times

the number of the Canadian stamps

∴ The number of the United States stamps = 1.5 x

∵ Kurt has a collection of 155 United States and Canadian stamps

- Add the two numbers of stamps and equate the answer by 155

∴ x + 1.5 x = 155

- Add like terms

∴ 2.5 x = 155

- Divide both sides by 2.5

∴ x = 62

∵ The number of United States stamps = 1.5 x

∴ The number of United States stamps = 1.5(62)

∴ The number of United States stamps = 93 stamps

Kurt has 93 United States stamps in his collection

Clarissa helps her mom put the 200-Newton lawn mower in the back of her mom’s truck. They lift the mower up from the ground to t

Anarel [89]

Answer:

220 N * m or 220 J

Step-by-step explanation:

We have that the work formula would be the applied force multiplied by the distance traveled, that is:

W = F * d

In this case the F is 200 N and the distance is 1.1 meters, therefore we replace:

W = 200 * 1.1

W = 220 N * m = 220 J

Therefore the work carried out by Clarissa and her mom is 200 joules.

Which statement correctly explains the association of the scatterplot

Blababa [14]

Answer:

B. Since the y - values decrease as the x - values increase the scatter plots show a negative association.

Step-by-step explanation:

A positive association would be the y - values and the x - values both increases.

I hope this helps!
