It is false that the area of a person's yard can be measured in cubic feet. It is always measured in square feet, because cubic feet add another dimension, which is height, and height is not measured in a yard.
Answer:
x=0
y= -1
Step-by-step explanation:
x−2y=2 - eq 1
3x+2y=−2 - eq 2
x−2y=2
(3x+2y)+(x−2y)=−2+2
x−2y=2
3x+2y+x−2y=0
x=0
y= -1
STEP 1:
convert gallons to cups & calculate total number of cups
1 gallon= 16 cups
= 8 gallons * 16 cups/gallon
= 128 cups total
STEP 2:
calculate total cups estimated for 20 guests
= 20 guests * 2 cups/guest
= 40 cups needed for guests
STEP 3:
subtract the difference between step 1 and step 2 to find leftover punch
= 128 cups - 40 cups
= 88 cups leftover
OR
GALLONS LEFTOVER
= 88 ÷ 16 cups/gallon= 5 1/2 gallons
ANSWER: There will be 88 cups or 5 1/2 gallons of punch leftover.
Hope this helps! :)
The weight would the hedgehog lose during 115 day in hibernation is 3.45 ounces.
<h3>How much weight would the hedgehog lose during 115 day in hibernation?</h3>
Using proportions, it exits found that the hedgehog loses 3.45 ounces after 115 days of hibernation.
A proportional relationship exists modeled by: y = kx
In which k exists the constant of proportionality.
In this problem, the ratio between the weight loss after x days in hibernation is given by:
k = 0.24/8 = 0.84/24 = 2.25/75 = 2.79/93 = 0.03
Since this ratio exists constant, the relationship is proportional, modeled by:
y = 0.03 x
The weight lost after 115 days of hibernation is y(115), hence:
y = 0.03(115) = 3.45
The hedgehog loses 3.45 ounces after 115 days of hibernation.
