divide 320 by 8 and get 40 cause ratio is 1:8 so answer is 40:320
Представьте дробь - 7/9 в виде дроби с знаменателем 27 7/17 в виде дроби с знаменателем 102 13/16 в виде дроби с знаменателем 80 11/13 в виде дроби с знаменателем 78
Answer:
I will answer in English, you can translate it after, as this is math, will be easier to read.
This can be translated to:
Present the fraction:
a) - 7/9 as a fraction with 27 denominator
b) 7/17 as a fraction with 102 denominator
c) 13/16 as a fraction with 80 denominator
d) 11/13 as a fraction with 78 denominator
a) We can multiply both numerator and denominator by the same number, and the quotient remains the same:
We know that 9*3 = 27
then: (-7/9)*(3/3) = -21/27
b) Here we can use that 102 = 17*6
Then we multiply the numerator and denominator by 6:
(7/17)*(6/6) = 42/102.
c) We can use that 16*5 = 80.
Then we should multiply both denominator and numerator by 5.
(13/16)*(5/5) = 65/80
d) We can use that 6*13 = 78, then we can multiply both denominator and numerator by 6.
(11/13)*(6/6) = 66/78
Find the exact value of Cosine (alpha + beta) given sin Alpha = two-fifths for Alpha in Quadrant II and Cosine Beta = one-third for Beta in Quadrant IV.
The exact value of cos (α + β) is (4√2-21) / 15.
What is angle?An angle is the formed when two straight lines meet at one point, it is denoted by θ.
Given that,
Sin α = 2/5, and α is in second quadrant,
cos β = 1/3 , and β is in fourth quadrant
Since, α is in second quadrant, the value of cos α will be negative.
The value of cos α, by right angle triangle property,
cos α = -√21 / 5
Since, β is in the fourth quadrant, the value of sin β will be negative.
The value of sin β = - 2√2 / 3
Cos (α + β) = cos α.cos β - sin α. sin β
Substitute the values here,
Cos (α + β) = (-√21 / 5) . 1/3 - 2/5. ( - 2√2 / 3)
= -21/15 + 4√2/15
= (4√2-21) / 15
The value of cos (α + β) is (4√2-21) / 15.

what is the slope intercept formula
Answer:
y=mx+b
Step-by-step explanation:
Answer:
y=mx+b
Explanation:
The slope-intercept formula is y=mx+b. The b represents the y-intercept, which is the point where a line on a graph meets the y-axis. The coordinates for this would be (0,b). The m represents the slope, which is the rate of change. The x represents any x variable that you plug in. The y represents the y variable.

For shipping packages, UPS charges $7.00 for the first pound, and $0.20 for each additional pound. FedEx charges $5.00 for the first pound and $0.30 for each additional pound. How many pounds will it take for UPS and FedEx to cost the same? Using p for the number of pounds, write and solve and equation to represent this situation.
Answer:
x=20
Step-by-step explanation:
7+0.20x=5+0.30x
then take the 7 and subtracet the 2 from it, then take the 0.30 and subtract the 0.20 from it then you should get 2=0.10x
then to get rid of the 0.10 you take it and divide it from the 2 which gives you 20 then you have 20=x and thats your answer

What is the equation of the line in the graph?
Answer:
y=5
Step-by-step explanation:
That is literally what horizontal lines' equations would be like.
The slope would be 0, so y=0x and the y-intercept would be 5 so y=0x+5 which is useless to keep the 0x so it becomes y=5.
Answer:
I think the answer is y=5

Holly stops to drink 5 ounces of water every two miles she
runs. The further that Holly runs, the more she drinks water.
Complete the table by writing two equivalent ratios
Answer:
the amount of water she drinks is x, the mileage is y:
x y
2 miles 5 oz
4 miles 10 oz
6 miles 15 oz
the ratios would be 4/10 and 6/15
Step-by-step explanation:
for every 2 miles Holly runs, she drinks 5 oz of water, right? the ratio is 5:2, so if you were to come up with other numbers that match the ratio, they have to be divisible by the parts of the ratio. so if she runs 2 miles, she drinks 5 oz. if she runs 4 miles, then she drinks 10 oz.
think of a ratio like a fraction (in this case it would be 2/5). if you were to make equivalent ratios, then the two fractions would have to be equal, right? well, when you simplify all of the numbers listed in the table above after making them into fractions, they would all go back to 2/5, so the numbers i came up with above are equivalent ratios, meaning they have the same value when simplified.
hopefully that helps and isn't too confusing! if you need other help, let me know! :)
