Which equation matches the function described by the table?
A)y = 5x

B)y=x+2

C)y = 5x + 2

D)y 6x-1

Answers

The actual answer is C. y = 5x + 2.

This is the answer because look at the table. I am gonna plug in the numbers.

2 = 5(0) + 2.

7 = 5(1) + 2.

12 = 5(2) + 2.


As you can see all those statements are true.

I don’t know how to explain it without talking and pointing, but basically all you have to do is plug the numbers into the equations and see which one is true.

Answers

Answer:

900g

Step-by-step explanation:

This is a case of direct variation as the weight will increase with the number of toys.

hence, 4/600 = 6/x

4x = 3600 (cross multiplication)

x = 900

Hence the weight of 6 such toys is 900g.

Step-by-step explanation:

hope that helped

Answer:

Step-by-step explanation:

The area of a square is the side squared.

A=s^2, if s=4/5 then

A=(4/5)^2

A=16/25

So the area is 16/25 yd^2 as a fraction or 0.64 yd^2 as a decimal.

The total mass of two cows is 96 kilograms. The mass of one of the cows is at least 20 kilograms more than the other. The mass of the lighter cow is more than 35 kilograms. What are the three possible masses of the heavier cow?

Answers

9514 1404 393

Answer:

  {58, 59, 60} kg

Step-by-step explanation:

Let x represent the mass of the heavier cow. Then the mass of the lighter cow is 96 -x.

The inequalities regarding the relative masses are ...

  x ≥ 96-x +20 . . . . . the heavy cow is at least 20 kg heavier

  96 -x > 35 . . . . . . . the lighter cow is more than 35 kg

__

Adding x to the first inequality makes it ...

  2x ≥ 116

  x ≥ 58

Adding x-35 to the second inequality makes it ...

  61 > x

So the mass of the heavier cow must be in the range ...

  58 ≤ x < 61

Possible whole-number masses for the heavier cow are ...

  58 kg, 59 kg, 60 kg

the geometric mean of 2 numbers is 20. one of the numbers 50. what is the other
number?

Answers

Answer:

8

Step-by-step explanation:

Let x = the unknown no.

Then

[tex]\frac{50}{20} = \frac{20}{x}[/tex]

50x = 400

 x = 8

If the geometric mean of two numbers is 20, one number is 50 then the other number is 8

What is geometric mean?

"The geometric mean is the average rate of return of a set of values calculated using the products of the terms."

Formula to calculate geometric mean is

[tex]GM = \sqrt{x_{1}.x_{2} }[/tex]

Here,

GM = 20

[tex]x_{1}=50\\ x_{2} =?[/tex]

Substitute the values in the formula

[tex]20=\sqrt{50.x_{2} }[/tex]

Squaring on both sides

[tex]400=50(x_{2})\\ x_{2} =\frac{400}{50} \\x_{2}=8[/tex]

Hence, the other number is 8.

Answer:

I believe the answer is D: 300 inches

Step-by-step explanation:

This might be incorrect, but here's how I see the answer:

First I found the perimeter of one square.

2 + 3 = 5^2= 10

10 inches is the perimeter of one square.

Then, since there is 30 rectangles, and each perimeter is 10 inches long, then you would simply need to multiply the two numbers.

30 * 10 = 300 inches of red thread will be needed.

Answer:

300 in

Step-by-step explanation:

2+2+3+3 = 10

Perimeter 10 for one rectangle.

Multiply 10 by 30 to find out the total perimeter for 30 rectangles.

10 x 30 = 300

(correct) arccos47.3°20.57

Step-by-step explanation:

1. The mnemonic SOH CAH TOA tells you the relationship between angle E and the given sides is ...

  Cos = Adjacent/Hypotenuse

  cos(E) = 19/28

  E = arccos(19/28) . . . . the inverse cosine function is used

__

2. E = arccos(19/28) ≈ 47.3°

__

3. You can either use the Pythagorean theorem to find DF, or you can use the sine relation.

  Sin = Opposite/Hypotenuse

  sin(E) = DF/28

  DF = 28·sin(E) = 28·sin(47.268°) . . . . original unrounded answer for E

  DF ≈ 20.57

or ...

  DF = √(DE² - EF²) = √(28² -19²) = √423 ≈ 20.56696...
