Answer:
Step-by-step explanation:
<em>17.</em>
sin20° =
x = 1 ÷ sin20°
<em>x</em> ≈ <em>2.9238</em>
cos20° =
y = x ÷ cos20°
<em>y</em> ≈ 2.9238 ÷ cos20° ≈ <em>3.11</em>
<em>18.</em>
<em>x = 2√3</em> ≈ 3.46
<em>y = √3</em> ≈ 1.732
Answer:
324
Step-by-step explanation:
L = 4W
P = 2L + 2W = 90
---
2L + 2W = 90
2(4W) + 2W = 90
8W + 2W = 90
10W = 90
---
W = 9
L = 36
---
A = 324

Answer:
The word problem is "How many $25 are there in $125?"
<em></em>
Step-by-step explanation:
Given

Required
Write a word problem for the expression
We start by solving the given equation

Divide both sides by $25



This implies that there are 5, $25 in $125
<em>Hence; The word problem is "How many $25 are there in $125?"</em>

Answer:
34.5 square meters
Step-by-step explanation:
We assume you want to find the area of the shaded region. (The actual question is not visible here.)
The area of the triangle (including the rectangle) is given by the formula ...
A = 1/2bh
The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...
A = (1/2)(11 m)(9 m) = 49.5 m^2
The rectangle area is the product of its length and width:
A = LW
The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...
A = (5 m)(3 m) = 15 m^2
The shaded area is the difference between the triangle area and the rectangle area:
shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2
The shaded region has an area of 34.5 square meters.
Assuming the five frame is for the number five (5) then place 5 counters in the frame.
