Answer:
x = 2
or 14.8
Step-by-step explanation:
First find the missing leg of the right triangle.
8²-3²=x²
x =
then double is to get x in the drawing
x = 2 or 14.8
The answer rewritten is z^2/25
Answer:
9/16 m.
Step-by-step explanation:
When you cut two pieces along its diagonal it causes it to be two congruent triangular pieces.
<em>You need to multiply the length and the width to find an area:
</em>
1 1/2 × 3/4
<em>Now you need to change it into an improper fraction:</em>
1*2+1 = 2+1 = 3; this gives us 3/2:
3/2 × 3/4 = 9/8 = 1 1/8
<em>Dividing it by 2:</em>
9/8 ÷ 2
Answer:
a. false
b. true
c. true
d. true
e. false
Step-by-step explanation:
a. False. The "unit rate" is 19.75 gallons per minute. The "unit" of a "unit rate" is in the denominator. Here, the denominator of the rate is 1 minute.
__
b. True. A graph of a proportional relationship is a straight line through the origin.
__
c. True. In 5 minutes, the water in the pool will increase by 98.75 gallons, about 100 gallons.
__
d. True. The ratio of a y-value to an x-value will always be 19.75. That is the meaning of this proportional relationship.
__
e. False. The points (8, 158) or (7.5949, 150) will be on the graph. The point (8, 150) will not.
