RE-ASKED

Answers

Answer 1
Track teaches you to be able to achieve your best speed in one of the quickest ways possible. The activity supports the skill because the more mitochondria you have, the more energy you are able to produce during exercise, which will enable you to run with greater speeds. If track is done regularly, it increases the size of the mitochondria. Giving you more energy, which will generate more speed. ( Hope this helps! (: )

Answers

Answer:

it is 2/3.

Step-by-step explanation:

please mark as brainliest .

2/3

As x increases by 1
Y decreases by a rate of 2/3.
6x2/3=4
4x2/3=8/3
And so on
To find 2/3, all you need to do is find how y is changing.
First of all, we know that y is decreasing as x increases so the rate is less than 1.
Take y2/y1 to get m or the rate
Ex. 4/6=2/3 which is less than 1!

Step-by-step explanation:

The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 meters. What is x, the width of the original rectangle on the left? Round to the nearest hundredth if necessary.

A) 5 meters
B) 8 meters
C) 10 meters
D) 12 meters

Answers

X=5



Explanation:


If the triangle on the rights perimeter is 24 and two of the lengths are 8 then we know 8+8=16 24-16=8 8/2=4
So the triangle on the right has the numbers 8 and 4 as it’s length and width

So then you would find out how much it was dilated to get from 30 to 24
30/24 and you get 1.25 so you multiply 4 by 1.25 and get 5, and then to double check you can multiply 8 by 1.25 and get 10 then add it all together
5+5+10+10=30 so you know that’s correct.

subtract the 14 because it says it is in neither.

Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.

Could someone please find the rate and y-intercept for these two points? (2,2) and (3,4) the help would be greatly appreciated!!

Answers

First use a formula to find rate of change
so a formula most commonly used is (y^1-y^2)/(x^1-x^2)

m= (y^1-y^2)/(x^1-x^2)
=m=(4-2)/(3-2)
=m=2/1
2/1 can also be expressed as just 2 since anything divided by 1 is just itself

Now use the formula y=mx+b to find the y intercept

use either of your two given point to susitute y and x

y=mx+b
Substitute your values
=(4)=(2)(3)+b
Calculate
=4=6+b
Subtract both sides by 6
=-2=b

Therefore the rate of change is 2/1 and the y-intercept is -2

The ratio of bananas to total fruit is 13:21

Step-by-step explanation:

Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.

Answer: 13:21

Find the slope...........

Answers

First thing to do is find out the coordinates of two points on the graph (I will use the ones that have been marked by the red dots):

Point A: (3, -1)
Point B: (1, 2)

Then we will use the slope formula to work out the slope:

y₂ - y₁ / x₂ - x₁

Substitute in our points:

2 - (-1) / 1 - 3

Then we work out the expression (remember a negative and a negative make a positive!):

3 / -2

Then we check if we can simplify this fraction, which in this case we cannot.

Therefore the slope of that line would be:

3 / -2

(remember to write it as a fraction!)

The table shows the relationship between X and Y.

11 | 599.5


Which equation models this relationship?

A. y = 53x

B. y = 53.5x

C. y = 54x

D. y = 54.5x


PLEASE ANSWER I NEED THIS THE ANSWER NOW

Answers

Answer: C. y = 54x



Explanation:

Hope this helps you :)

An equation which models the relationship between X and Y is

y = 54.5x

The correct answer is option (D) y = 54.5x

What is equation?

"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."

From given data we can observe that,

163.5/3 = 54.5                           ...................(1)

327/6 = 54.5                              ...................(2)

599.5/11 = 54.5                          ...................(3)

From (1), (2) and (3),

y/x = 54.5

⇒ y = (54.5)x

Therefore, an equation which models the relationship between X and Y is y = 54.5x

The correct answer is option (D).

Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.

Answers

Answer:

9.55 minutes

Step-by-step explanation:

x hours to go to the river

0.25-x hours to come back, since 15 minutes is 0.25 hr.

to the river 40 mph * x hours =40x miles

from the river 70 mph (0.25-x) hours=17.5-70x

those two are equal

40x=17.5-70x

110x=17.5

x=17.5/110=0.159 hours

9.55 minutes
