Answer:

143/220= 0.65 so 65%

Step-by-step explanation:

Answer:

65%

Step-by-step explanation:

Cross, multiply and divide method has saved my life with these problems, heres how to do it.

Set up like this:

143 x

------- = -------

220 100

Multiply 143 by 100, then divide that by 220.

x= 65, so she has read 65%

Answer:

The correct answer will be X = 4

Step-by-step explanation:

Using Pythagoras

AB^2 + BC^2 = AC^2

2^2 + (2√3)^2 = AC^2

4 + (4*3) = AC^2

4+12 = AC ^ 2

AC ^2 = 16

AC = √16 = 4

Answer:

-6r+6

Step-by-step explanation:

Let us expand the expression:

8-(6r+2)=

8-6r-2=

6-6r

OR

-6r+6

I hope this helps! :)

Answer:

6r+6

Step-by-step explanation:

we dont know the variable's number value yet so you can't solve anything with the 6r. We use distribbutive property and solve 8-2 since the 8 is just subtracting everything in the parenthesis. 8-2=6 and you can't do anything with the 6r so the expression would end up as 6r+6.

Answer:

The table will be:

x              0      1       2      -1       3       1/3

y=3x-1     -1       2      5      -4      8       0

Step-by-step explanation:

We are given the equation: y = 3x-1 and we need to fill the table.

We have to put value of x and find value of y

When x = 0

y= 3(0)-1 = 0-1 = -1

So, x=0, y=-1

When x = 1

y=3(1)-1=3-1 = 2

So, x=1, y=2

When x = 2

y=3(2)-1=6-1 = 5

So, x=2, y=5

Now, we are given y=-4 and we need to find x

y=3x-1

-4=3x-1

-4+1=3x

3x=-3

x=-3/3 = -1

So, y = -4, x = -1

Now, we are given y=8 and we need to find x

y=3x-1

8=3x-1

8+1=3x

3x=9

x=9/3 = 3

So,  y = 8, x = 3

Now, we are given y=0 and we need to find x

y=3x-1

0=3x-1

0+1=3x

3x=1

x=1/3

So,  y = 0, x = 1/3

The table will be:

x              0      1       2      -1       3       1/3

y=3x-1     -1       2      5      -4      8       0

Answer:

D

Step-by-step explanation:

7 is the number 175 percent of 4.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Let n be the required percentage.

So,

n percent of 4 is 7.

That means,

4 x n/100 = 7

n = 700/4

n = 175%

Therefore, 175% is the required percentage.

Answer:

D.)

Step-by-step explanation:

y = 5/x

so when the value of x triples, the new X becomes;

X = 3x

So,

Y = 5/ X

=> Y = 5/3x

=> Y = 1/3 . 5/x

=> Y = 1/3 . y

so the new value of y ( Y ) is 1/3 times original y.

Hence, D. is the answer

Answer:lol it's -3

Step-by-step explanation: it's 3 because you had dirt 45.50 in your account and then you have to get books and those books will cost $3 more which means that you don't have that money since it indicates that in the problem which means that it would be -3 because you don't have the money so that's why I think it's negative 3.

Answer:

1.22

Step-by-step explanation:

28/23=1.21739130435.

rounded to the nearest tenth would be:

1.22

The given number 28/23 is rounded to the nearest mile as 1.2.

The given fraction is 28/23.

The decimal number for the given fraction is 1.217

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

Here, in 1.217 digit in the hundredths place is 1, which is less than 5.

So, the digit in the tens place remain same and digits after tens place becomes zero.

That is, 1.2

Therefore, the given number 28/23 is rounded to the nearest mile as 1.2.

Answer: A. Contractor A. The probability that both conditions are met is 0.93

Step-by-step explanation:

Probability of two independent events happening can be found by multiplying them.

Probability of A doing the job on time and on budget:

= Probability that job is done on time * Probability it is done on budget

= 0.97 * 0.96

= 0.93

Probability of B doing the job on time and on budget:

= 0.93 * 0.98

= 0.91

Contractor A has the better probability at 0.93 so should be chosen.

Step-by-step explanation:

Add up the four test scores (80, 95, 85, x) then divide by 4 and set that result equal to 88. The equation you get is (80+95+85+x)/4 = 88. Now solve for x.

(80+95+85+x)/4 = 88

(260+x)/4 = 88

4*(260+x)/4 = 4*88

260+x = 352

x+260 = 352

x+260-260 = 352-260

x = 92
