Answer: 5:8, .625, 62.5%
Step-by-step explanation:
5 to 8 is already a ratio. Then all you have to do is divide it. Then to get the percentage, move the decimal point over to the right 2 places.
with the water saver on (from #1) how many gallons of water would be used (60 minutes in an hour) long shower?
Step-by-step explanation:
60 minutos long shower -7.5,-220
help? mathhhhhhhhhhhhhhhhhhhhhhhhhhhh
Answer:
a + 20 = 7*12 (multiplied both sides by 12)
a + 20 = 84 (calculated 7*12)
a = 84 - 20 (subtracted 20 on both sides)
a = 64 (calculated 84-20)

Answer:
1: 11
2: 1
3: -9
4: -49
Answer:
See screenshot below
Step-by-step explanation:
All you have to do it substitute the x in the rule with the x in the table. Let's do the first one in the steps below.Write the equation with the x value: y = -10(-1) + 1-10 × -1 = 10Plug 10 in: y = 10 + 110 + 1 = 11So, y = 11Now that you know how to find the rest, go ahead and do it (my answer doesn't show the work, but the answers are in the screenshot below)I hope this helps!

A forest has 6500 trees.
The trees are beech or maple.
number of beech : number of maple = 1.6:1
(a) What fraction of the trees are beech?
Answer:4000
Step-by-step explanation:
Given
There are a total of 6500 trees
The ratio of beech and maple is [tex]1.6:1[/tex]
So, no of beech are [tex]\frac{1.6}{2.6}\times 6500=4000[/tex]
no of maple are [tex]\frac{1}{2.6}\times 6500=2500[/tex]

How can an area model help you set
up an equation for a problem situation?
Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the or the and define the length and width of the rectangle.
We can break one large of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the or quotient.
Step-by-step explanation:
For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

which of the trigonometric ratios has a value that is undefined?
Answer:
[tex]\tan \left(\frac{\pi }{2}\right)[/tex]
Step-by-step explanation:
We know that tan(x) is defined as sin(x)/cos(x):
[tex]\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\[/tex]
[tex]\tan \left(\frac{\pi }{2}\right) = 1/0 \\[/tex]
1/0 is undefined as 0 is in the denominator
Answer true/false. If false, give a counterexample

Answer:
TABLE 1:
88

TABLE 2:
176
164
132
108
90
81
60
28
11
2
Step-by-step explanation:
When two angles are complementary they add up to 90 degrees
so for example if angle 1 is 2 angle two must equal 88 (they have to add up to 90)
When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)
Answer:
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
Step-by-step explanation:
complementary means they add up to 90°
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
supplementary means they add up to 180°
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
