Answer:
50
Step-by-step explanation:
115 = p
115 = 2m + 15
-15 -15
100 = 2m
/2 /2
50 = m

hi uhm help im bad at math
Answer:
All it says is PDF NOT AVAILABLE.. can you type the question out.
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! :)
Find the measure of x
Answer:
Wdym
Step-by-step explanation:
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

Answer:
what the hell is this question
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 solution to the equation 5(x-3) = 2(x+3)?
calculate the estimate of the mean height of the students in cm and explain your answer
Step-by-step explanation:
we find the average height of each height first,
t¹= (120+124)/2
=244/2
=122
t²= (124+128)/2
t²= 252/2
t²= 126
t³= (128+132)/2
t³= 260/2
t³= 130
t⁴= (132+136)/2
t⁴= 268/2
t⁴ =134
t⁵= (136+140)/2
t⁵= 276/2
t⁵= 138
so multiplying each height by its frequency we can find the total height, so we have..
total height= (122*7)+(126*8)+(130*13)+(134*9)+(138*3)
= 854+1008+1690+1206+414
= 5172
mean height = total height/total frequency
= 5172/40
=129.3

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.
A = 16/4 marked blocks = 25%
B = 16/8 marked blocks = 50%
C = 16/6 marked blocks = ?
D = 16/10 marked blocks = 62,5%
So answer would be A
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.
Look at the number line below. b fa and b are equal distances from 0, which of the following is true?
A a+b=0
B. a/b=1
C. a-b=0
D. ab = 1
Answer:
a

I am pretty sure it is 10.5
Step-by-step explanation:
Answer:
10.5
Step-by-step explanation:
your equation: DT = DH + HT
HT = 2DH
so now your equation is DT = DH + 2DH
plug in your values: 3.5 + 2(3.5)
you get DH = 10.5

A package of nuts weights 3/4 of a pound. One serving size is 1/8 of a pound, how many servings in the package?
Answer: 6 servings
Step-by-step explanation:
One serving is 1/8 of a pound.
One package is 3/4 of a pound.
The number of servings therefore will be the number of times that 1/8 can go into 3/4.
= (3/4) / (1/8)
= (3/4) * (8/1)
= 6 servings
