Answer:

Huh, the answer option doesn't exist. The answer is 7.5 You can double check my answer by multiplying 7.5*4 because 25% is 1/4th of 100%.

Step-by-step explanation:

Use cross multiplication. I've heard it being called butterfly multiplication. I'll try to represent it as best as I can.

x           25

----   =  --------

30         100

You multiply 30 by 25 and x by 100

x*100=30*25

Then solve for x

x*100=750

x=750/100

x=7.5

Hope this helps :)

Answer:

length = 62.41 inches

Step-by-step explanation:

Using pythagoras theorem -

Let

a = hypotenuse

b = height

c = length

a^2 = b^2 +c^2

75^2 = 41.6^2 + c^2

Therefore,

75^2 - 41.6^2 = c^2

5625 - 1730.56 = c^2

389.44 = c^2

square root (389.44) = c

62.40544848 = c

Answer:

62 inches.

Step-by-step explanation:

and finally, take the square root of the number we are left with after subtracting [tex]B^{2}[/tex] , or 1730.56, from 5625, or [tex]C^{2}[/tex]

5625 - 1730.56 =3894.44

[tex]\sqrt{3894.44}[/tex] = 62.405

Answer:

x  ≥ -7/2

Step-by-step explanation:

3 + 2x ≥ -4

Subtract 3 from each side

3-3 + 2x ≥ -4-3

2x ≥ -7

Divide each side by 2

2x/2  ≥ -7/2

x  ≥ -7/2

Steps to solve:

3 + 2x ≥ -4

~Subtract 3 to both sides

3 - 3 + 2x ≥ -4 - 3

~Simplify

2x ≥ -7

~Divide 2 to both sides

2x/2 ≥ -7/2

~Simplify

x ≥ -3.5

Best of Luck!

Answer:

(0,5) is on the y-axis

Step-by-step explanation:

Since the x value is 0, it is not left or right of (0,0), thus it does not leave the y-axis. Since its y-value Is 5, it goes up 5 units from (0,0) but still it does not leave the y-axis.

Answer:

it is on the y-axis

Step-by-step explanation:

Answer:

Step-by-step explanation:

Assuming KH is a straight line with K and H being the beginning and the end of the line. If J is between H and K, it means that J is a point on line HK. Therefore, we can say that

HJ + JK= KH

If HJ = 4x + 9, JK = 3x + 3 and KH = 33, it means that

4x + 9 + 3x + 3 = 33

4x + 3x = 33 - (9 + 3)

7x = 21

Dividing both sides of the equation by 7, it becomes

x = 21/7 = 3

Therefore, HJ = 4 × 3 + 9 = 21

Answer:

9

Step-by-step explanation:

Answer:

2 millimeters

Step-by-step explanation:

Ethan used the scale 1 millimeter : 5 meters.

This means that 1 millimeter in the drawing represents 5 meters in actual life.

The actual  length of the garage is 10 meters. Therefore:

5 meters = 1 millimeter

=> 10 meters = (10 * 1) / 5 = 2 millimeters

The garage is 2 millimeters long in the drawing.

Answer:

76/15

Step-by-step explanation:

Drug A=2/5

Drug B=5/3

Drug C=9/3

Add the drug combinations together

Drug A + B + C=2/5 + 5/3 + 9/3

The L.C.M of the denominators is 15

=6+25+45/15

=76/15

Or

=5 1/15

Answer:

Diego's mistake is that he multiplied the exponents, instead of adding. The answer should be [tex]2^{3+2} = 2^{5}[/tex]

Step-by-step explanation:

Suppose we have a base a, and two exponents, b and c, we have that:

[tex]a^{b} \times a^{c} = a^{b+c}[/tex]

In this problem:

[tex]a = 2, b = 3, c = 2[/tex]

Diego's mistake is that he multiplied the exponents, instead of adding. The answer should be [tex]2^{3+2} = 2^{5}[/tex]

Answer:

If you divide any number by zero, the answer will be zero.

Step-by-step explanation:

You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.

All other statements are true.

An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.

The sum of a number and zero will be that number. You are technically adding nothing.

[tex]4+0=4[/tex]

The product of any number and zero is zero. This is the "Multiplication Property of Zero".

[tex]4*0=0[/tex]

"If you divide any number by zero, the answer will be zero." should be the correct answer.

"If you divide any number by zero, the answer will be zero." should be the correct answer.

Addition property of zero:

The addition property of zero says that a number does not change when adding or subtracting zero from that number.

Multiplication property of zero:

The multiplication property of zero says that zero times any number is equal to zero.

Explanation for correct option:

If you divide any number by zero, the answer will be zero.

You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.

All other statements are true.

Explanations for other options:

An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.

The sum of a number and zero will be the same number. You are technically adding nothing.

The product of any number and zero is zero. This is the "Multiplication Property of Zero".

"If you divide any number by zero, the answer will be zero." should be the correct answer.

Answer:

commutative property:

A + B = B + A

So we have

3 + (5 + 7)  = (5 + 7) + 3

Now distributive means that:

A + (B + C) = (A + B) + C

So  (5 + 7) + 3 = 5 + (7 + 3)

now the equation is easier to solve, because 7 + 3 = 10

5 + (7 + 3) = 5 + 10 = 15

Answer:

Use the commutative property of operations to reverse the numbers in the expression.

✔ 3 + (7 + 5)

Use the associative property of operations to change the grouping after reversing the numbers in the expression.

✔ (3 + 7) + 5

Evaluate the expression.
