Answer:
70%
Step-by-step explanation:
We can first find the fraction
35/50
We know that percent is out of 100 so multiply the top and bottom by 100
35/50 * 2/2 = 70/100
The percent is 70%
Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
Answer:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
5-2x=12
-2x=12-5
-2x=7 (multiplying by -1)
2x=-7
x= -7/2 = -3,5
Answer:
y = -1/2x +2
Step-by-step explanation:
2y = -x +4
divide both sides by 2
y = -1/2x +2
