The answer to that is 80 percent as a fraction is 8/10
Answer:
25.2294 feet
Step-by-step explanation:
We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).
First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:
y + 55 + 63 = 180
y = 62°
The relation between the angles and the distances are:
25 / sin(y) = x / sin(63)
25 / 0.8829 = x / 0.8910
x = 25 * 0.8910 / 0.8829 = 25.2294 feet
20 because it stated the number 50 times
Answer:
26,000
Step-by-step explanation:
There are 4 places to be filled.
_ _ _ _
Now we put in each place the number of possible characters that can go there.
<u>26</u> <u>10</u> <u>10</u> <u>10</u>
Finally we multiply all the numbers together.
26 * 10 * 10 * 10 = 26,000
Answer: 26,000
Answer:
13) (-2,-3) 14) (7,-4) 15) (-8,7)
Step-by-step explanation:
13) y=8x+13
-4x-5y=23
use substitution
-4x-5(8x+13)=23
distribute -5 in the parenthesis
-4x-40x-65=23
-44x-65=23
add 65 on both sides
-44x=88
divide both sides by -44
x=-2
for y...
y=8(-2)+13
y=-16+13
y=-3
answer is (-2,-3)
14) -3x-y=-17
y=-4x+24
use substitution
-3x-1(-4x+24)=-17
distribute the -2 in the parenthesis
-3x+4x-24=-17
x-24=-17
add 24 on both sides
x=7
for y...
y=-4(7)+24
y=-28+24
y=-4
answer is (7,-4)
15)5x+4y=-12
y=-2x-9
use substitution
5x+4(-2x-9)=-12
distribute 4 in the parenthesis
5x-8x-36=-12
-3x-36=-12
add 36 on both sides
-3x=24
divide both sides by -3
x=-8
for y...
y=-2(-8)-9
y=16-9
y=7
answer is (-8,7)
