Answer:
there are 18 girls
Step-by-step explanation:
for every 2 boys there are 3 girls
so then you can say 2/5 of the class are boys and 3/5 are girls
and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.

In ΔWXY, y = 88 cm, x = 85 cm and ∠X=70°. Find all possible values of ∠Y, to the nearest 10th of a degree.
Answer:
All possible values of ∠Y are 76.6° and 103.4°
Step-by-step explanation:
In Δ WXY
∵ x is the opposite side of ∠X
∵ y is the opposite side of ∠Y
→ By using the sine rule
∴ [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]
∵ x = 85 and y = 88
∴ m∠X = 70°
→ Substitute them in the rule above
∴ [tex]\frac{85}{sin(70)}[/tex] = [tex]\frac{88}{sin(Y)}[/tex]
→ By using the cross multiplication
∴ 85 × sin(Y) = 88 × sin(70)
→ Divide both sides by 85
∴ sin(Y) = 0.9728582427
∴ m∠Y = [tex]sin^{-1}[/tex](0.9728582427)
∴ m∠Y = 76.62037845
→ Round it to the nearest tenth
∴ m∠Y = 76.6°
→ The other value of ∠Y is the obtuse angle supplement of ∠Y
∴ m∠Y = 180 - 76.6
∴ m∠Y = 103.4°
∴ All possible values of ∠Y are 76.6° and 103.4°

What is the solution to the following equation? -32-8x=-7x+8(8x-4)
the answer to your question is x=0
X=0
−32−8x=−7x+8(8x−4)
−8x−32=−7x+8(8x−4)
−8x−32=−7x+64x−32
−8x−32=57−32
−8−32+32=57−32+32

David wants to earn more than $26 trimming trees. He charges $6 per hour and pays $4 in equipment fees. What are the possible numbers of hours David could trim trees? Use for the number of hours. Write your answer as an inequality solved for
Answer:
The inequality is :
6h - 4 > 26
The possible numbers of hours David could trim trees is more than 5 hours
Step-by-step explanation:
David wants to earn more than $26 trimming trees. He charges $6 per hour and pays $4 in equipment fees.
Let the number of hours David works for be represented by h
More than means greater than , hence we use the inequality sign >
Hence, we have the inequality
$6 × h + $4 > $26
6h - 4 > 26
6h > 26 + 4
6h > 30
Divide both sides by 6
6h/6 > 30/6
h > 5
Hence, if David want to earn more than $26 he has to trim trees for more than 5 hours

A triangular pyramid and its net are shown. Rain uses the calculations below to conclude that the surface area of the triangular pyramid is 238.5 square inches. 3 x 10 x 13) + ( x 10 x 8.7) 3 (65) + 43.5 238.5 Is Rain correct? Use the drop-down menus to explain your reasoning.
Answer:
Yes, Rain is correct
238.5 square inches
Step-by-step explanation:
Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)
= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)
= 43.5 + 3(65)
= 43.5 + 195
= 238.5 square inches
The surface area of the triangular pyramid = 238.5 square inches
The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the net attached:
Surface area = 3(1/2 * 10 * 12) + (1/2 * 10 * 8.7)
Surface area = 223.5 in²
The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

~AnonymousHelper1807which of the ordered pairs is a solution of the following equation
5x-2y=20
We want to see which ordered pairs are a solution of the equation:
5x - 2y = 20
The ordered pairs are not given, so I will give a general answer, finding the general form of all the ordered pairs that are solutions.
We start with the equation:
5x - 2y = 20
First, we need to isolate one of the variables, let's isolate y.
2y = 5x - 20
y = (5/2)*x - 20/2
Then we get:
y = (5/2)*x - 10
From this, all the ordered pairs (x, y) that are solutions of this equation are given by:
(x, (5/2)*x - 10)
Then to get the points we just need to replace the "x" with numbers, for example for x = 0 we get the solution:
(0, (5/2)*0 - 10) = (0, -10)
For x = 1 we get the solution:
(1, (5/2)*1 - 10) = (1, -15/2)
And so on.
