Answer:

The height of the boat ramp is 25 feet

Step-by-step explanation:

we know that

In the right triangle ABC

Let

h the height of the boat ramp in feet

see the attached figure

sin(30^o)=\frac{h}{50} ----> SOH (opposite side divided by the hypotenuse)

solve for h

h=sin(30^o)(50)=25\ ft

I need help asap plz
Lostsunrise [7]

Answer:

A

Step-by-step explanation:

The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are x and y.

To find the constant of proportionality, all we have to do is divide any value of y by its corresponding value of x. Let's take the values in the first row of the table. We know that x=2 and y=12, so the constant of proportionality is \frac{y}{x}=\frac{12}{2} =6. Hope this helps!

Answer:

6 × 9 = 54

42 ÷ 7 = 6

56 ÷ 7 = 8

Step-by-step explanation:

Given:

6 × 9 = 54

8 × 4 = 34

42 ÷ 7 = 6

64 ÷ 9 = 7

56 ÷ 7 = 8

Now it need to verify,

6 × 9 = 54 this is correct

42 ÷ 7 = 6 This is also correct

56 ÷ 7 = 8 This is correct

Use slopes to determine if the lines 5x−4y=−1 and 4x−y=−9 are perpendicular.
stich3 [128]

Answer:

Not perpendicular

Step-by-step explanation:

Convert it to y-intercept form first:

5x - 4y = -1

-4y = -5x - 1

y = 5/4x + 1/4

4x - y = -9

-y = -4x - 9

y = 4x + 9

y = 5/4x + 1/4

y = 4x + 9

From the slopes, they are not considered perpendicular because one of the line slope is not a <em>negative reciprocal</em> of the other line slope.
