∠1 + ∠3 + 90° = 180°

∠1 + ∠3 = 90°

∠3 = ∠4 (vertically opposite angles)

∠1 + ∠4 = 90°

Therefore, the answer is ∠1 + ∠4

Charlie gathers apples, pears, and plums. The numbers of apples and plums are 10-partners. There are the same number of apples a

aalyn [17]

Answer:

The total number of pieces of fruit that Charlie can gather ranges from 11 to 19.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Numbers of apples and plums are 10-partners, it means that the sum of apples and plums is 10.

Number of apples and pears are the same.

2. How many pieces of fruit can Charlie gather?

Apples = a

Plums = p

Pears = s

a + p = 10

Possible values of a and p:

1 + 9, 2 + 8, 3 + 7, 4 + 6, 5 + 5, 6 + 4, 7 + 3, 8 + 2, 9 + 1

Possible values of s:

1, 2, 3, 4, 5, 6, 7, 8, or 9

Therefore, the total number of pieces of fruit that Charlie can gather ranges from 11 to 19.

What is the sum of 7/22 and 9/22

natulia [17]

when u have a common a denominator then you just add the numerator that would be 7 and 9. 7 + 9= 16
so ur solution would be 16/22 and then u would simplify by dividing both values by 2.
so the solution is8/11

The volume of a cone is 540pi. work out the height of the cone.

Bas_tet [7]

Answer:

I would need the radius of the cone to answer this completely, bit I can get you super close and explain it.

Step-by-step explanation:

The formula for a cone is

$\pi \times r {}^{2} \times \frac{h}{3}$

From there, I started plugging in numbers. I set this equation equal to 540pi because both if them are the volume, so they are equal and I simplified as much as I could from there. First off, the pi cancel each other out since they're on both sides of the equation. From there you have this equation:

$r {}^{2} \times \frac{h}{3} = 540$

Then, I multiplied both sides by 3 to get rid of the fraction on the left side of the equation:

$r {}^{2} h = 1620$

Finally, I got rid of the "squared" by putting a square root over both sides if the equation, getting this:

$r \times h = 40.249$

If I knew the radius. I could get the answer by dividing both sides by the radius.

Good luck!
