Answer:
37 1/8
Step-by-step explanation:
The problem probably assumes direct variation
y=kx
IF so, then plug in the values and solve for k
27=k(8)
k = 27/8
y= (27/8)x. Now let x = 11
y = (27/8)11 = 27(11)/8 = 37.125 = 37 1/8
y = 37 1/8
the problem is making some assumption about the relation between x and y. The simplest assumption that's likely is direct variation, that x and y are linearly related. The graph is a straight line through the origin with slope = 27/8
48 x 2/3 = 32. For dilation just multiply each side by the dilation factor.
Answer:
Step-by-step explanation:
Make a system of equations
Give the hot and cold faucets variables
Set x to be the minutes it takes for the hot water faucet to fill up the tub and Set y to be the minutes it takes for the cold water faucet to fill up the tub
She first equation is x = 2y because the hot faucet takes <em>2 times</em> as much time as the cold water
The second equation is x + y = 5 because if you add the number of minutes each takes to fill a tub, it will add up to 5 minutes
Now you have the equations
x = 2y
x + y = 5
So you can plug the first equation in for x in the second one to make
2y + y = 5
which equals 3y = 5
Then you divide 3 from both sides to get
y = 
Since y is the number of minutes the cold water faucet takes to fill the tub, then the cold faucet takes
minutes for the cold water faucet to fill the tub itself
Answer:
7.2 in² or 7.2 inches squared
Step-by-step explanation:
Area is a measure of how much space there is on a flat surface.
To find the area, just multiply the length and width of the figure.
2 × 3.6 is 7.2
When you find the area, you have to square it.
So, the answer is 7.2 in², or 7.2 inches squared
