Answer:

55.6

Step-by-step explanation:

We have been given that the current cost of a typical desktop computer is $745. The cost in year 1983 was $1,445 with fewer capabilities.

To find CPI for the desktop computer, we will use formula:

\text{CPI }=\frac{\text{Price of goods in given year}}{\text{Price of goods in base year}}* 100  

\text{CPI for the desktop computer}=\frac{\$745}{\$1445}*100

\text{CPI for the desktop computer}=0.5155709342*100

\text{CPI for the desktop computer}=51.55709342\approx 55.6

Therefore, the CPI for the desktop computer is 55.6.

Y=2x−1
lord [1]

Answer:

(1,1) is a solution of the system.

Step-by-step explanation:

Let's solve the system.

y = 2x - 1

5x - 4y = 1

In the first equation, y is already separated as a function of x. So we replace in the second equation;

5x - 4(2x - 1) = 1

5x - 8x + 4 = 1

4 - 1 = 8x - 5x

x = 1

y = 2x - 1 = 2(1) - 1 = 1

(1,1) is a solution of the system.

Find the area of the figure.
Nady [450]

Answer:

Explanation:

So you want to start by finding the area of the big square.

We know the width to the big square is 60cm. The length to the big square is

=

56

Big square

A

r

e

a

=

L

⋅

W

=

56

⋅

60

=

3360

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.

Little square

A

r

34

=

816

The area enclosed is the area of the big square minus the area of the little square.

=

2544

So the area enclosed is

The number p and −1.2 are additive inverses. Drag and drop −1.2 and p to their correct positions on the number line. Drag and dr
klemol [59]

Answer:

p=1.2

Step-by-step explanation:

Additive inverse of any number means a number which can be added to the original number to get

Two numbers are said to be additive inverse of each other if sum of both numbers is 0. For example if 5 is the given number then -5 will be it's additive inverse. So to find additive inverse, we basically change the sign of number.

Given number p is additive inverse off -1.2 so p must be 1.2.

Sum will obviously be 0.

So to graph them on number line, we make a point at -1.2, 1.2 and at 0 for their sum.
