Answer:

72

Step-by-step explanation:

Just multiply all them

Answer:

y = 75

Step-by-step explanation:

Given that:

   y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]

⇒ y = k[tex]\sqrt{x}[/tex]

where k is the constant of proportionality.

When y = 45, x = 81, then;

45 = k[tex]\sqrt{81}[/tex]

45 = 9 k

k = [tex]\frac{45}{9}[/tex]

  = 5

k = 5

So that,

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

the value of y when x = 225 is;

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

  = 5 x [tex]\sqrt{225}[/tex]

  = 5 x 15

y = 75

Answer:

d 18

Step-by-step explanation:

Given expression

7 + (16-7) ÷ 3 + 8

= 7 + 9 ÷3 + 8

= 7 + 3 + 8

= 18

Hope it will help :)

Answer:

d. 18

Step-by-step explanation:

We are given an expression and are asked to solve, when solving, we need to follow the PEMDAS rule. Commonly used when so many factors and signs are at hand.

PEMDAS -

Parenthesis

Exponents

Multiply

Divide

Addition

Subtraction

This rule is showing what to do first when you have long expressions like these, do as followed and solve the parenthesis first :

7 + (16 - 7) / 3 + 8

7 + 9 / 3 + 8

Now divide :

7 + 9 / 3 + 8

7 + 3 + 8

Now that we only have to add, add all numbers together :

7 + 3 + 8

18

Answer:

22.5

Step-by-step explanation:

Answer:

x = 22.5

Step-by-step explanation:

x - 9= 3/5x

3/5x - x = -9

-2/5x = -9

x = 22.5

Answer:

1. -5

2. 4

3. 10

Step-by-step explanation:

this equation is in vertex form. Points 1 and 2 are the coordinates of the center of the circle (5 is the x coordinate, -4 is the y coordinate). To find the center of the circle, take the values of the given (5, -4) coordinate, and switch their sign (5 becomes -5, -4 becomes 4).

to find part 3, you will need to plug in the values of the second coordinate (-3, 2).

If you need to find the radius of (3), find the square root of whatever answer you got.

1. (x-5)^2 + (y+4)^2 = ___

2. (-3-5)^2 + (2+4)^2 = ____

3. (-8)^2 + (6)^2 =___

4. 64+36 = 100

Answer:

I much don't know much about this but I'm going to say the answer is 0

Answer:

100

Step-by-step explanation: A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number.

Answer:

100,000,000

Step-by-step explanation:

10^6= in this case, just add 5 zeros to the 10. each zero multiplies the number by 10

Answer:

c) 9x and 8x

Step-by-step explanation:

3x + 8 + 3y + 8x

the like terms are 3x and 8x since they both have the same variables

8 and 3y are not the like terms because there's no other number with the same variable as them.

Answer:

C. 5[tex]\pi[/tex] > 15

Step-by-step explanation:

In the given series of inequalities, the inequality sign determines the final outcome.

A. 4[tex]\pi[/tex] - 2 < 10

4[tex]\pi[/tex] < 12

[tex]\pi[/tex] < 3

Since [tex]\pi[/tex] < 3, then the inequality is false

B. [tex]\pi[/tex] + 9 < 12

[tex]\pi[/tex] < 3

Since [tex]\pi[/tex] < 3, then the inequality is false

c. 5[tex]\pi[/tex] > 15

[tex]\pi[/tex] > 3

Since [tex]\pi[/tex] > 3, then the inequality is true

D. 6 > 2[tex]\pi[/tex]

3 > [tex]\pi[/tex]

Since [tex]\pi[/tex] < 3, then the inequality is false

Thus, the only inequality that is true is option C.

Answer:

undefined, 0 does not equal 1

Step-by-step explanation:

in the end, x is cancelled out and you are left with 0=1 which is not true

Answer:

0=4

Step-by-step explanation:

1/2x + 1/2x = x + 1

x/2 + x/2 = x + 1

2x + 2x/4 = x + 1

4x = 4(x + 1)

4x = 4x + 4

4x - 4x = 4

0=4
