The ratio shows that for 2 cups of lime juice there needed proportion of 8 cups of limeade.
and, the ratio involve a part and the whole.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Use a product of two binomials to find a polynomial that represents the area of Roberto's plot.
Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2
Manco went scuba diving. As he dove deeper, the water pressure around him increased at a constant rate. The table compares Mancini's depth (in meters) and the water pressure around him(in atmospheres). what was the pressure around manco when he was 30 meters deep?
Answer:
4.0 atm
Step-by-step explanation:
it looks to be a proportional ratio so for every meter pressure increases by .1 atm so if you add .8 to 3.2 you get 4 atm

-2(7 – n) + 4
What is the answer to this any body know it??????????
Answer:
2n+10
Step-by-step explanation:
you just distribute the -2 and you get -14+2n+4 and then add and you'll get 2n+10
if you are solving for the variable n then you would want your equation like this 2n+10=0
next you would put the 10 on the other side of the equation and have 2n=-10
finally you would divide by 2 and get n=-5

Sunita creates a scale model of an aeroplane. The scale of the model is 4 cm to 15 m. Sunita's model has a wingspan of 17 cm. What is the wingspan of the real aeroplane?
Answer:
36.43m
Step-by-step explanation:
Let the wingspan of the real aeroplane = x
The scale of the model is 4 cm to 15 m.
= 4: 15 = 4/15.
Sunita's model has a wingspan of 17cm.
Hence:
4cm/15m = 17cm/xm
Cross Multiply
4x = 15 × 17
4x = 255
x = 255/4
x = 36.428571429 m
Approximately = 36.43 m
Therefore, the wingspan of the real aeroplane is 36.43m

8x² + 16x - 62 = -5, solve by completing the square. PLEASE HELP IVE BEEN STRUGGLING FOR HOURS
Answer:
x=-1+[tex]\frac{1}{4}[/tex][tex]\sqrt{130\\}[/tex] or x=-1+[tex]\frac{-1}{4}[/tex][tex]\sqrt{130}[/tex]
Step by step:
Step 1: Subtract -5 from both sides.
8x2+16x−62−(−5)=−5−(−5)
8x2+16x−57=0
For this equation: a=8, b=16, c=-57
8x2+16x+−57=0
(plus-minus) = ±
Step 2: Use quadratic formula with a=8, b=16, c=-57.
x=[tex]\frac{-b(plus-minus)\sqrt{x} b^2-4ac}{2a}[/tex]
x=[tex]\frac{-(16)(plus-minus)\sqrt{(16)^2-4(8)(-57)} }{2(8)}[/tex]
x=[tex]\frac{-16(plus-minus) \sqrt{2080} }{16}[/tex]
ANSWER:
x=-1+[tex]\frac{1}{4}[/tex][tex]\sqrt{130}[/tex] or x=-1+[tex]\frac{-1}{4}[/tex][tex]\sqrt{130}[/tex]

this year Benny is 12 years old and his mom is 48 years old what percent of his mom's age is Benny's age
Answer:
25%
Step-by-step explanation:
Let's set up a percent proportion:
12/x = 48/100
To solve for x, we would do:
x = (12*100)/48 = 1200/48 = 25
x = 25%
In my opinion, the easiest way to do this would be to look at this and notice that 12 * 4 =48 so that means 12 is 1/4 of 48 and 1/4 = 25%.

Step-by-step explanation:
An angle measures 160° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
The two angles are 10 degrees and 170 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Let the angle be called "x", and the supplementary angle be called "180-x"
Converting words to math: x-160=180-x
Add x to both sides: 2x-160=180
Simplify: 2x=20
Divide by 2: x=10

John rode 2 kilometers on his bike. His sister Sally rode 6,000 meters on her bike. How many more kilometers did Sally ride?
Answer:
I don't understand, please write again
Answer:
Sally rode 4 kilometers more than her brother.
Step-by-step explanation:
1,000 meters = 1 kilometer
So if you convert Sally's meters into kilometers, you get 6 kilometers. John rode 2 kilometers so you do 6 kilometers - 2 kilometers = 4 kilometers.
Now you got your answer!
Hope this helped.
