Answer:
a. We need 1/4 for each feeder
b. To fill each feeder we need 1.25 pounds
c. We need 60 ounces to fill three bird feeders
Step-by-step explanation:
Five pounds of birdseed is used to fill 4 identical bird feeders,
a. We divide all the birdseed in 4 feeders, so, we need 1/4 for each feeder.
b. If we use 5 pounds for the 4 feeders, so each feeders will take 1/4 of the 5 pounds
=1/4 x 5=1.25 pounds
c. To fill three bird feeders we have to multiply the amount of pounds by feeder by 3 feeders
=1.25 pounds x 3
= 3,75 pounds
If 16 ounces are a pound
so, 16 x 3.75 = 60 ounces
(n+11)(n-4) is your answer
Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
Well the problem came out kind of weird but the prime factors of 28 are 2•2•7
Hope this helps!
Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(n) = n ^ 4 + 5n ^ 3 + 2n ^ 2 - 5n + 13
<h3>To find </h3>
<h3>Solution</h3>
<u>Substituting n with -2</u>
- f(-2) =
- (-2)^4 + 5(-2)^3 + 2(-2)^2 - 5(-2) + 13 =
- 16 - 40 + 8 + 10 + 13 =
- 7
