<em>Greetings from Brasil...</em>
Using sine, we will be able to find the value of X
SEN 17 = X/47
X = 47 · SEN 17
X = 47 · 0,29237
X = 13,741
<h3>X ≈ 13.7</h3>
Answer:
1. 0.9
2. 9 tenths
3. 56.077
4. 6.65
1. 1.7 - 0.8 = 0.9
2. 1.7 - 0.8 = 0.9. 0.9 = 9 tenths
3. 84.637 - 28.56 = 56.077
4. 7 - 0.35 = 6.65.
These are the answers and explanations. Hope it helps!
The answer is that it cannot be modeled with a rectangle.
(8-3)²-(5-2)²
Follow the PEMDAS
P-Parenthesis
E-Exponents
M/D-Multiplication/Division
A/S-Addition/Subtraction
clear the numerals in the parenthesis:
(5)²-(3)²
Now do the exponents:
=25-9
=16
Its just: (5)²-(3)²
Answer:
The number of boys are 18 and the number of girls are 30.
Step-by-step explanation:
The ratio of number of girls to the boys = 3 : 5
Let the number of girls is g and boys is b initially.
b : g = 3 : 5
5 b = 3 g ..... (1)
Now, girls are 6 + g and boys are b - 9
So, the ratio is
(b - 9) : (6 + g) = 1 : 4
4 b - 36 = 6 + g
4 b - g = 42 .... (2)
From ( 1 ) and ( 2 )

And , g = 5 x 18/3 = 30
So, the number of boys are 18 and the number of girls are 30.
