Please help!! I've been stuck on this for a while, any help is greatly appreciated!!

What is the equation that represents the table below?

The algebraic expression to express the function of the total number of times Alex skipped rope will be  y = 50x.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Alex skipped a jump rope 50 times every minute as shown by this table. x equals the number of minutes, and y equals the number of times she skipped the rope.

Then the algebraic expression to express the function of the total number of times Alex skipped rope will be

y = 50x

where y be the number of skipped rope and x be the number of minutes.

Answer:

radius=3

Step-by-step explanation:

volumes of a cone = 1/3πr²h

12π = 1/3× π × r² × 4

37.7 = 12.6r²/3

cross multiply

37.7×3=12.6r²

113.1=12.6r²

make r² subject of the formula

r²=113.1÷12.6

r²=8.976

r=√8.976

r=2.996

r=3.0 (to the nearest tenth)

Answer: 10 degrees

Step-by-step explanation:

Since it is a right triangle the angle is 90 degrees.

So, 90 degrees -50 degrees is equal to 40 degrees.

40 divided by 4 is 10.

So your answer is 10 degrees.

Answer:

x = -7

Step-by-step explanation:

3x + 6 = x - 8

-x -x

(subtract x from both sides)

2x + 6= −8

Answer:

60

Step-by-step explanation:

45 is a vertical angle so the angle opposite will also be 45 degrees. There is also 75 in the bottom left corner of the trianlge. 45 + 75 is 120. In a triangle the angles all equal 180 degrees. subtract 120 from 180. 180-120=60.

Answer:

351cm³

step by step explanation:

Volume of the prism:

=[1/2×(a+b)×h]×l

=[1/2×(5+8)×6]×9

=(1/2×13×6)×9

=(6.5×6)×9

=39×9

=351cm³

The correct range is (80, 112).

The correct option is (D).

Mean is also said to be arithmetic mean. The meaning of mean is to evaluate the average. It is defined as the average of the given numbers.

As per the given data:

We are given the mean of the sample.

The mean of the sample = 96

In each option, a range is given.

We have to find out which is the correct range for the given mean.

For a range (a, b) the mean is given by:

mean = (a + b)/2

By using the above definition and checking all the options:

For (76, 108)

mean = (76 + 108)/2 = 92, Not the correct range

For (82, 114)

mean = (82 + 114)/2 = 98, Not the correct range

For (78, 110)

mean = (78 + 110)/2 = 94, Not the correct range

For (80, 112)

mean = (80 + 112)/2 = 96, The correct range

The correct range is (80, 112).

Hence, the correct range is (80, 112).

Step-by-step explanation:

There are 48.7 cups in total

2/18 of 48.7 cups is needed for volcano

Total amount needed for experiments are :

2/18 of 48.7 = 97.4/18 = 5.411 cups

If Rocco has 48.7 cups of flour in his storage unit and He needs 2/18 of  that amount to use for his homemade volcano then total number of cups needed for his experiment is 5.411

fraction is a mathematical expression representing the division of one whole number by another

Here given that  Rocco has 48.7 cups of flour in his storage unit. He needs 2/18 that amount to use for his homemade volcano.

Hence total number of cups needed for his experiment can be written as :

[tex]\frac{2}{18}\times \text{Total cups}[/tex]

[tex]\frac{2}{18}\times 48.7\\\\\\\frac{2}{180}\times 487\\\\\\\\\frac{974}{180}\\\\ = 5.411[/tex]

If Rocco has 48.7 cups of flour in his storage unit and He needs 2/18 of  that amount to use for his homemade volcano then total number of cups needed for his experiment is 5.411

Answer:

14 mL

Step-by-step explanation:

because 1 ml = 25 mg we just need to divide 350 mg by 25 mg to know how many mL are equivalent to 350 mg.

350/25 = 14

therefore 14mL is equivalent to the 350 mg of the drug.

Hence,  the liquid will need to be given is [tex]14ml[/tex] which is equivalent to the [tex]350[/tex] mg of the drug.

What is an equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here,

[tex]1ml=25mg[/tex], here we need to divide [tex]350mg[/tex] by [tex]25 mg[/tex]  to know how many [tex]ml[/tex]are equivalent to [tex]350 mg.[/tex]

i.e., [tex]\frac{350}{25}=14[/tex]

Therefore, 14mL is equivalent to the [tex]350[/tex] mg of the drug.

Hence,  the liquid will need to be given is [tex]14ml[/tex] which is equivalent to the [tex]350[/tex] mg of the drug.

Answer:

x = 2[tex]\sqrt{5}[/tex]

Step-by-step explanation:

'x' can represent the hypotenuse of a right triangle with a base of 4 (11-7) and a height of 2

use Pythagorean Theorem to find 'x':

2² + 4² = x²

4 + 16 = x²

x² = 20

x = [tex]\sqrt{20}[/tex]

x = [tex]\sqrt{4}[/tex]·[tex]\sqrt{5}[/tex]

x = 2[tex]\sqrt{5}[/tex]
