Answer:

Step-by-step explanation:

x + y = 19

1.5x + .75y = 20.25

x + y = 19

150x + 75y = 2025

-150x - 150y = -2850

150x + 75y = 2025

-75y = -825

y  =  11 bags of chips

x + 11 = 19

x = 8 hot dogs

mojhsa [17]

Answer:

about 16°

Step-by-step explanation:

Make sure your calculator is in degree mode.

Drawing the right triangle, we see that the shorter leg is 34 meters, and the longer leg is 122 meters. So the angle of elevation is:

\tan( \alpha )  =  \frac{34}{122}

\alpha  =  { \tan }^{ - 1}  \frac{34}{122}  = 15.57

A trampoline has an area of 49pi square feet. What is the diameter of<br> the trampoline?
Alex17521 [72]

Answer:

The diameter is 14π

Step-by-step explanation:

We know the area of a circle is πr^2

let 49π=πr^2

Cancel the π's, and you get 49=r^2

Take the square root and you get r=7

The diameter of a circle is 2πr.

2π(7)=14π.

Find the coordinates of the midpoint of HX. H(5.5, -4.75) and X(3.75, -2.75)
MAXImum [283]

( 4.625, - 3.75 )

the midpoint of (x₁, y₁ ) and (x₂, y₂ ) is

[\frac{1}{2}(x₁ + x₂ ), \frac{1}{2}(y₁ + y₂ ) ]

here (x₁, y₁ ) = (5.5, - 4.75 ) and (x₂, y₂ ) = (3.75, - 2.75 )

[ \frac{1}{2}(5.5 + 3.75 ), \frac{1}{2}(- 4.75 - 2.75 ) ]

= (4.625, - 3.75 ) ← midpoint of HX
