Answer:

$6 per quart

Step-by-step explanation:

Since we are trying to find out how much money a quart of paint will cost, we need to find out how many quarts are in one gallon.

There are 4 quarts in a gallon, therefore we take $24 divided by 4 and get $6 per quart.

the height in feet above the ground of an arrow after it is shot can be modeled by y=-16r^2+63r+4.Can the arrow pass over a tree
miss Akunina [59]

Answer:

yes

Step-by-step explanation:

y=-16r^2+63r+4

maximum value of y :

y'=0

-32r +63=0

r= 63/32

y = -16(63/32)²+63(63/32)+4

= -4 + 124 + 4 = 124 ft

124 > 68

the Arrow can pass over the tree

Answer:

336 sq un

Step-by-step explanation:

The area of a rhombus is pq/2 where p and q are the diagonals.

you have:

p = 12 + 12 = 24

q = 18 + 10 = 28

so the formula would be:

24 * 28 / 2 = 336 sq un

In a triangle , the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 100 m
madam [21]

Answer:

The three unknown angles X, Y , and Z are:

X = 40, Y = 20, and Z = 120

Step-by-step explanation:

Let's name X the measure of the first angle, Y the measure of the second one, and Z that of the third one.

Then we can create the following equations:

X = 2 Y

Z = 100 + Y

and

X + Y + Z = 180

So we use the first equation and the second one to substitute for the variable X and Z in the thrid equation:

2 Y + Y + (100 + Y) = 180

4 Y + 100 = 180

4 Y = 80

Y = 80/4 = 20

Then X = 40, Y = 20, and Z = 120

Use the given information to determine the exact trigonometric value.<br> (in the image attached)
notka56 [123]

Answer:

OPTION B: $ \frac{-2\sqrt{5}}{5} $

Step-by-step explanation:

Given $ cot \theta = -\frac{\sqrt{5}}{2} $

We know that, $ \frac{1}{cot \theta} = tan \theta $

$ \implies tan \theta = \frac{1}{-\frac{\sqrt{5}}{2}} $

$ = -\frac{2}{\sqrt{5}} $

Multiplying and dividing by $ \sqrt{5} $, we get:

$ tan \theta = - \frac{2 \sqrt{5}}{\sqrt{5}\times \sqrt{5}}} $

$ \implies tan \theta = -\frac{2\sqrt{5}}{5} $

Hence, OPTION B is the answer.
