A rollercoaster rises 160 feet into the air before dropping 190
feet. What is the height of the rollercoaster

Answer: he is 11 years old

Step-by-step explanation: 44 divided by 4 = 11

Answer 44 divided by 4 (11)

Answer:

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

Answer:

125

Step-by-step explanation:

1/4 of 500 (the total number of girls) is 125.

HTH :)

Answer: I think its Consine

Step-by-step explanation:

Answer:

All it says is PDF NOT AVAILABLE.. can you type the question out.

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

Answer: D

Step-by-step explanation:

If my calculations are right, it should be d

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:

Answer:

10 x 11 to the 10th power

Step-by-step explanation

Answer: 6+x or x+6

Step-by-step explanation:

You are adding 6 to a number, in this case, we'll use x.

Answer:

40

Step-by-step explanation:

divide 320 by 8 and get 40 cause ratio is 1:8 so answer is 40:320

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

Answer:

78

Step-by-step explanation:

do 9x8= 72

then 72+6=78

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! :)  

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

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

Answer:

1st option!!

Answer:

what the hell is this question

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.

Answer:

nice

Step-by-step explanation:

Answer:

115

Step-by-step explanation:

I think 115 because The angles are 50, 65, 65. So just subtract 65 from 180 to get your answer. Or just add 50 and 65 to get your answer.
