Answer:
$15
Step-by-step explanation:
unit rate means how much he earns in 1 hour
so if he earns $60 in 4 hours
then you have to divide 60 by four
which gives you $15
that means he earn $15 in one hour
Answer:
B
Step-by-step explanation:
Using the method of cross- multiplication
A
7x = 252 ( divide both sides by 7 )
x = 36 ≠ 4
B
21x = 84 ( divide both sides by 21 )
x = 4
C
5x = 2 ( divide both sides by 5 )
x = 0.4 ≠ 4
D
5x = 200 ( divide both sides by 5 )
x = 80 ≠ 4
The proportion where x = 4 is B
Answer:
Step-by-step explanation:
(3,4)=x1,y1 (5,8)=x2,y2. The slope is calculated using formula: Slope =y2−y1x2−x1. =8−45−3. =42. =2.
Multiply 9*14=126
multiply 7*6=42
Answer:
x = 22√2
Step-by-step explanation:
In a triangle,
AB = 22
B = 90
C = 45
Now,
<em>sin </em><em>C </em><em>=</em><em> </em><em>opp/</em><em>h</em><em>y</em><em>p</em>
<em>sin </em><em>4</em><em>5</em><em> </em><em>=</em><em> </em><em>AB/</em><em>A</em><em>C</em>
<em>1</em><em>/</em><em>√</em><em>2</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>x</em>
<em><u>x = 22√2</u></em>
