Answer:

[tex]\% = 11\%[/tex]

Step-by-step explanation:

Given

[tex]Initial = \$13.50[/tex]

[tex]Final = \$14.99[/tex]

Required

Determine the percentage change

This is calculated as:

[tex]\% = |\frac{Initial - Final}{Initial} * 100\%[/tex]

[tex]\% = |\frac{13.50 - 14.99}{13.50}| * 100\%[/tex]

[tex]\% = |\frac{-1.49}{13.50}| * 100\%[/tex]

[tex]\% = \frac{1.49}{13.50} * 100\%[/tex]

[tex]\% = \frac{1.49* 100\%}{13.50}[/tex]

[tex]\% = \frac{149\%}{13.50}[/tex]

[tex]\% = 11.037037037\%[/tex]

[tex]\% = 11\%[/tex]

Answer:

52%

Step-by-step explanation:

Number of hours of sleep a student gets = 5.28hrs

A teacher wants the student to get = 8hrs of sleep

Unknown:

Percentage increase in the number of hours the student will sleep = ?

Solution:

  Percentage increase = [tex]\frac{New sleep hours - former sleep hours}{former sleep hours}[/tex] x 100

 Percentage increase  = [tex]\frac{8 - 5.28}{5.28}[/tex] x 100 = 51.5%

  Percentage increase  = 52%

Answer:

35

Step-by-step explanation:

Answer:

-35 meters

Step-by-step explanation:

He's below sea level, basically saying below 0= sea level.

Then it's basically saying -172+ 137 meters because the shark is going upwards 137 meters, which makes 137 positive. Dude, remember, up is positive and down is negative. So the answer to this problem would be -35 meters because of -172+137=-35. Hope this helped you.

Answer:

C

Step-by-step explanation:

The slope is 3. A perpendicular line has the complete opposite of the other. So if it is -1/3 slope for one line, the perpendicular line would be 3/1 which simplifies to 3. Hope this helps!

Answer:

21.2d + 12.4f

Step-by-step explanation:

Given that:

Width of rectangle = (5.5d+9.7f) centimeters

Length of rectangle = (5.1d-3.5f) centimeters

Perimeter of a rectangle : 2 (length + Width)

2 [(5.1d-3.5f) + (5.5d+9.7f)]

2[5.1d - 3.5f + 5.5d + 9.7f]

2[10.6d + 6.2f]

= 21.2d + 12.4f

Hence, the perimeter is :

21.2d + 12.4f)

Answer:

14 in

Step-by-step explanation:

Given:

Circumference of circle = 44 in

Required:

The length of the diameter of the circle.

SOLUTION:

Circumference of circle = πd

Circumference = 44 in

π = 3.14

d = ?

Plug the values into the formula

44 = 3.14*d

Divide both sides by 3.14

44/3.14 = d

14.01 = d

d ≈ 14 in

Answer:

b=2

Step-by-step explanation:

First multiply everything in the parenthesis by the 2 outside of them then combine like variables to get the equation 5b-6=4 then subtract 6 from both sides then divide by 5 to get b=2.

Step-by-step explanation:

Equation

7x - 15 = 1 → Move the -15, reversing the sign:

7x = 1 + 15 → Solve the sum:

7x = 16 → We have a fraction:

x = [tex]\dfrac{16}{7}[/tex]

x = 2.28571428571

To keep it simple, the answer could be just [tex]\dfrac{16}{7}[/tex].

Hope this helps!

Good studies! ☺

The solution of the equation for x is;

⇒ x = 16/7

What is an expression?

Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.

The expression is given as;

7x - 15 = 1

Now, Solve the expression for x by using inverse operations as;

7x - 15 = 1

Since 15 is subtract and inverse of subtraction is addition.

Hence,

Add 15 both side we get;

7x - 15 + 15 = 1 + 15

7x = 16

7 is multiply by x, and inverse of multiplication is divide;

So, Divide by 7 both side;

x = 16/7

Thus, The solution of the equation for x is;

⇒ x = 16/7

Answer:

x = 32

m∠7 = 94

m∠8 = 86

m∠3 = 94

Step-by-step explanation:

(2x + 30) + (3x - 10) = 180

5x + 20 = 180

5x = 160

x = 32

m∠7 = 2(32) + 30 = 94

m∠8 = 3(32) - 10 = 86

or

m∠8 = 180 - 94 = 86

m∠3 ≈ m∠7 (corresponding angles)

Answer:

The response variable is; reduction in the pain associated with sickle-cell disease.

Explanation:

Note, a response variable (dependent variable) simply refers to resulting effect (either significant or insignificant effect) of the independent variable on the subjects of the experiment.

In other words, the effect of the drug hydroxyurea after the experiment would show whether it leads to or not lead to a reduction in the pain associated with sickle-cell disease.

Answer:

|x |-7 = -5     ( x = -3 )

Step-by-step explanation:

Answer and Step-by-step explanation:

Solution:

Order of operations:

1- Parentheses

2- Exponent

3- Multiply

4- Divide

5- Subtract

By using these operations we can find out the solution of 4’s to create problems that will equal to     1 – 12.

1 = 44 / 44   or (4+4) / (4+4)

2= 4/4 + 4/4

3 = (4+4+4) /4

4 = 4 x (4 – 4) +4

5 = (4 x 4 + 4)/ 4

6 = 4 x .4 + 4.4

7 = 44 / 4 – 4

8 = 4 + 4.4 - .4

9 = 4/4 +4 +4

10 = 44 / 4.4

11= 4 / .4 + 4/4

12 = (44 + 4) / 4
