Answer:
<u>The answer is 1. 64 and 2. 60</u>
Step-by-step explanation:
Question 7. 75% of what number is 48?
Number = x
75%x = 48
3x/4 = 48 (75% = 3/4)
3x = 192 (Multiplying by 4 at both sides of the equation)
<u>x = 64</u> (Dividing by 3 at both sides of the equation)
<u>Part 75 Whole 48 Part 100 Whole 64</u>
Question 8. 120% of what number is 72?
Number = x
120%x = 72
12x/10 = 72 (120% = 12/10)
12x = 720 (Multiplying by 10 at both sides of the equation)
<u>x = 60</u> (Dividing by 12 at both sides of the equation)
<u>Part 120 Whole 72 Part 100 Whole 60</u>
Answer:
Shorter leg: 27 cm,
Longer leg: 36 cm,
Hypotenuse: 45 cm.
Step-by-step explanation:
Let x represent longer leg of the triangle.
We have been given that the shorter leg of a right triangle 9 cm is shorter than the longer leg. This means that the shorter leg of right triangle would be cm.
We are told that hypotenuse is 9 cm longer than the longer leg.This means that the hypotenuse of right triangle would be cm.
Now, we will use Pythagoras theorem to solve for x as:
Upon simplifying our equation, we will get:
Using zero product property, we will get:
Since longer side of a right triangle cannot be 0, therefore, longer side of the right triangle is 36 cm.
The shorter side of right triangle would be cm. Therefore, the shorter side of the right triangle would be 27 cm.
The hypotenuse of right triangle would be cm.Therefore, the hypotenuse of the right triangle would be 45 cm.
Answer:
marcel picked 4 apples
Step-by-step explanation:
18 = 4x + 2
solve for x
subtract 2 from each side
16 = 4x
divided by 4
16/4 = 4
Answer:
5 tickets and 4 drinks costs $43.
Step-by-step explanation:
You can solve with a simple equation:
<em>m = movie ticket</em>
<em>d = drink</em>
<em>t = total</em>
7m + 2d = t
7(5) + 2(4) = t
t = $43
Answer:
$120
Step-by-step explanation:
First you need to multiply all the box materials in box 1 and 2 separately(each dimension once you get the answers 1200 for box 1 and 1080 for box 2 you need to subtract 1080 from 1200 to get $120
