The width of a computer monitor is 28 cm. If the perimeter is 136 cm, what is the area of the computer monitor?
A. 896cm 2

B. 812 cm2

C.1,020 cm2

D. 1,120 cm2

Answers

Answer: D. 1,120 cm2

Step-by-step explanation: Perimeter is the adding of all four sides, so if you take the width and add it with itself, you can then subtract the perimeter with the added width. Now with this new number all you have to do is divide it by two, and now that you have the length you can multiply it with the original width to get the area.

The answer is D. When you have to find area you always multiply so in this case you will do 28cm times 136cm which equals 1,120cm2

Answer:

B. y = 1/2x - 2

Step-by-step explanation:

The slope-intercept form is:

y = mx + b

According to the table, point (0, -2) we see:

y-intercept is - 2

And using two points (4, 0) and (8, 2) we can find the slope:

m = (2 - 0)/(8 - 4) = 2/4 = 1/2

So the line is:

y = 1/2x - 2

Correct option is: B

Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years).

Previous equation answer:
Yes the values are the same
3r = 45
3(15) = 45

Answers

Answer:

3(15)+60p+65=45

Step-by-step explanation:

Paula’s age, p is 5/6 years.

Given that, Raul’s grandfather is Miguel age=65 years.

How do solve age problems?

Important Statements and Equations for "Problems based on Ages":

If the present age is y, then n times the present age = ny.If the present age is x, then age n years later/hence = x + n.If the present age is x, then age n years ago = x – n.The ages in a ratio a: b will be ax and bx.If the current age is y, then 1/n of the age is y/n.

Let Raul’s sister Paula's age be p and Raul’s age be r.

From the statement, Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister.

We can write the equation as follows r=65-60p

In part C:

39=3r-6

⇒r=15

So using the part C answer we get 15=65-60p

⇒60p=65-15

⇒p=5/6 years

Therefore, Paula’s age, p is 5/6 years.

Ming incorrectly says that this product is 4/63.
-(-4/9) · (-1/7)

a. What is the correct product?

b. What error could Ming have made?

Answers

Answer: -4/63

Step-by-step explanation: he put a positive sign instead of a negative in the 4

a. The correct product is -4/63.

b. Ming forgot to distribute two negative signs on the first term.

Sign changes when we do arithmetic operations ?

(-,-) = +. (+,+) = +. (-,+) = -. (+,-) = -.

For example -: 6 + (-3) here negative sign of 3 will distribute (+,-) and the end result will be negative ⇒ 6 - 3 = 3

According to the given question

Ming has given a product -(-4/9) · (-1/7) and he mistakenly said it is 4/63.

The given product is -(-4/9) · (-1/7)

= (4/9).(-1/7)

= -4/63.

Ming didn't notice that on the first term two negative sign will distribute and  make it positive and then multiplying it with a negative number will result in a negative number.
