I only know 9) and 10) sorry but here they are:
9) x=16 because ...
3x+20=5x-12
(-3x) (-3x)
20=2x-12
(+12) (+12)
32 = 2x
(32/2) (2x/2)
16=x

10) x=46
angles in quadrilaterals add to 360’
So you do ...
360-134-134-46= 46

This is all I know sorry. Hope you find some more help :)

Been posting this question for days now (Q5) ....pls I beg of you if you don't know don't reply ​
Firdavs [7]

Answer:

a. Another letter that have corresponding angles is the letter 'E'

b. Another letter that have alternate angles is the letter 'N'

Step-by-step explanation:

The capital letter 'F' can be described as letter can be presented as follows;

Two horizontal parallel lines touching and perpendicular to a common transversal

Therefore, the parallel lines in the letter 'F' and their common transversal form corresponding angles below each parallel line and the common transversal

The two horizontal lines in the capital letter Z and the inclined transversal form alternate angles between the transversal and the parallel lines, in the region between the parallel lines and on opposite sides of the transversal

a. Another letter that have corresponding angles is the letter 'E'

b. Another letter that have alternate angles is the letter 'N'

1. Based on the information in the table, is the cost of the apples proportional to the weight of apples?
lina2011 [118]

Answer:

  1. yes
  2. no

Step-by-step explanation:

When a number of similar calculations are required, a spreadsheet can reduce the tedium.

1. The price is a constant $1.88 per pound, so is proportional to the weight.

_____

2. The price is not proportional to the number of toppings.

__

The cost of the pizza is $8.99 plus $1.50 per topping. The base cost being non-zero ensures that the overall cost is not proportional to the number of toppings.

An observer (O) is located 500 feet from a school (S). The observer notices a bird (B) flying at a 39° angle of elevation from h
Serhud [2]

Answer:

h=404.89

Step-by-step explanation:

We are looking for side h, which is opposite of the observer. We know that the side adjacent to the observer is 500 feet. We also know that the angle from the observer to the bird is 39°. Because we have these values, SOH CAH TOA tells us that we should use tangent, opposite over adjacent.

We can set up our equation as follows:

tan(39°)=h/500

We can then solve for h:

500*tan(39°)=h

h=404.89
