What does it mean to get a 150% salary raise? Explain in words and then give an example showing a calculation.

Answers

Answer: 150% salary raise means that there is a increment in the salary of 150%.


Step-by-step explanation:

Let Marina is getting a salary of $4500 after working as a teacher in a school. She has got 150% salary raise this month.

Then her new salary = $4500+150% of $4500

=4500+(150)/(100)*4500\n=4500+150*45\n=\$4500+\$6750=\$11250

Thus, Marina will get $11250 as new salary.



Giving a 150% salary raise would mean that your salary is going up by 150% meaning if you have a 46,000 salary, the raise would make it to where your salary is now going to be 69,000. 46,000*150%=69,000 or 46,000*1.5=69000

The circumference of a circle is C = 7.64(pi) inches. what is the length of the radius and diameter.

Answers

The exact circumference is shown there.  The exact circumference has the length of the diameter and pi.  Like,  say a diameter was 8 inches.  It would be 8(pi).

The diameter here is 7.64 inches.  A radius is half as big as a diameter,  so divide the diameter by 2.  The radius is 3.82 inches.

Hope this helps!

When dividing fractions, it is most helpful to change a mixed number into a

Answers

Into an improper fraction. An improper fraction is a fraction where the denominator is smaller than the numerator. 

Example: Mixed number: 1 2/3
                Improper fraction: 5/3 
Yes, it is. Actually, it depends on if the fractions you're dividing have like or unlike denominators. If they have unlike, then yes. Let's say I was dividing 3/4 by 1/2. I would first, find the LCM (least common denominator) which in this case is already 4. I would then make 1/2 into 4ths. Lets see:1/2x 2/2 (how many times 2'goes into 4) and I get 2/4. Now I'm ready to divide. Sorry, this problem you can't divide but you can subtract:3/4-2/4= 1/4Hope I helped!

What is the surface area of the rectangular pyramid shown? 59.5 cm2 63 cm2 75.5 cm2 99 cm2

Answers

Answer:

Option D.

Step-by-step explanation:

In this question figure of pyramid is attached below the question .

Surface area of the rectangular pyramid :

Area of the Base = Length × Width

                            = 10 × 2 = 20 cm²

Area of Lateral #1 = (1)/(2)(P)(L)

                             = (1)/(2)(10*6.3)

                             = 31.5 cm²

Area of Lateral #2 = (1)/(2)(8* 2)

                               = (16)/(2)

                               = 8 cm²

Surface area of the pyramid = 20 + 2(31.5) + 2(8)

                                                = 20 + 63 + 16

                                                = 99 cm²

Surface area of the pyramid is 99 cm²

Answer:

99cm2
