Answer:

1. 52

2. 75

3.

Step-by-step explanation:

PEMDAS! I love PEMDAS problems!

1. (63 - 3) / 6 + 42

(P means parenthesis first - after you do this step the parenthesis goes away)

60 / 6 + 42

(We have no exponets so we move on to doing division and multiplication from left to right)

10 + 42

(Now we add!)

52

2. (8*4+5^2) + 8

(Now we have to do PEMDAS inside the parenthesis - So we have to do exponents first)

(8*4 + 25) + 8

(Now you do multiplication from left to right)

(32 + 25) +8

(Now that we only have one sign in our parenthesis we can solve it to get rid of it.)

67 + 8

(now add!)

75

3. (13 + 5)^2 + 8 / 2

(We have to do parenthesis first because of the P)

18^2 + 8/2

(now we do exponents)

324 + 8 / 2

(Now we divide and multiply from left to right)

324 + 4

(now add!)

328

Answer:

3

Step-by-step explanation:

Dilated has the meaning of getting larger. So in this case, if it has any meaning at all and the answer is "no answer given" then all you have to do is look at the y intercept.

The shorter line has a y intercept of 1

The longer line has a y intercept of 3

Therefore the dilation factor is 3

However if your teacher is a stickler for a better proof, then you could compare lengths.

Shorter line

Two end points

(-6,-3)     (6,5)

Distance = sqrt( (-6-6)^2 + (-3-5)^2 )

distance = sqrt (144 + 64)

distance = sqrt(208)

distance = 14.42

Longer line

(-12,-5)   (24,19)

distance = sqrt(24 - - 12)^2 + (19 - -5)^2 )

distance = sqrt( 36^2 + 24^2)

distance = sqrt (1296 + 576)

distance = sqrt(1872)

distance = 43.27

The best answer is =3

Step-by-step explanation:

3^-2= 1/9

Normally 3^2 is 9 but since the power is a negative, you but the 9 as the bottom or denominator of a fraction.

Answer:

Answer:

19 : 10 = 19 : 10

Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 19 and 10 is 1

Divide both terms by the GCF, 1:

19 ÷ 1 = 19

10 ÷ 1 = 10

The ratio 19 : 10 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

19 : 10 = 19 : 10

Answer:

100 miles per hour.

Step-by-step explanation:

To solve this we need to divide 5 by 5 to find the answer for 1 hour rather than 5.

5 / 5 = 1

Following the logic of, “what you do to one side, you must do to the other” i will divide 500 by 5.

500 / 5 = 100

Mr B was traveling at 100 miles per hour.

Answer:

probably of a head= 1/2

probably of a multiple of 3 (either 3 or 6)= 2ways*1/6 as 1/6 is the prob of any one side

Step-by-step explanation:

Answer:

1/12 or 8.3%

Step-by-step explanation:

To find probability, mark the how many sides you are testing in your probability over the possible outcomes.

Die: 1 side out of 6 sides is the test = 1/6 probability abt. 16%

Coin: 1 side out of 2 sides is the test = 1/2 probability 50%

To find total probability of getting a 5 on the die and a heads on the coin is found by multiplying the two fractions together.

1/6 x 1/2 = 1/12

abt. 16% x 50% = abt. 8%

Answer:

d=3 1/4

Step-by-step explanation:

Answer: 3 1/4 or 37/4

Step-by-step explanation:

3 1/4 would have an extra fraction, subtracting would make both sides equal. 37/4 is 3 1/4 as an improper fraction instead of a mixed number.

Answer:

the answer is 1

Step-by-step explanation:

Answer:

x=1

Step-by-step explanation:

for y²=4ax

directrix is x=-a

for y²=4x ,directrix is x=-1

for y²=4(x-2), shift directrix 2 units right.

so directrix is x=-1+2=1

so for (y+4)²=4(x-2) directrix is x=1

  C  They do not go through the origin

Step-by-step explanation:

The graph of a proportional relationship is a straight line with a y-intercept of 0. These lines do not go through the origin, so do not describe a proportional relationship.

Answer:

3

Step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

21 different integers represent the sum of two or more members of the set {-4, -3, -2, -1, 0, 1, 2, 3, 4}

A number system is defined as a system of writing to express numbers.

First you need to find the extremes. What is the largest negative value, and what is the largest positive value?

1+2+3+4 =10 so the largest positive value is 10. Therefore the largest negative value must be -10.

Next, we need to determine which integers from 5 to 10 can be covered.

1+4=5

2+4=6

3+4=7

3+4+1=8

2+3+4=9

And 1 to 4 can all be achieved by adding that value and 0.

0=-1+1

So, all the integers from -10 to 10 represent the sums of two or more numbers from the set.

10 positive + 10 negative + 0 = 21 integers.

Hence, 21 different integers represent the sum of two or more members of the set {-4, -3, -2, -1, 0, 1, 2, 3, 4}

Step 2: Find mean

And we have our final answer!

Answer:

Second choice, 4/3

Step-by-step explanation:

With the two point already highlighted, find the difference they have in x and y.  (-1, 2) and (2, 2)

x = -1 - 2 = -3

y = -2 - 2 = -4

The slope is y/x so it would be -4/-3 or just 4/3 because the negatives cancel each other out and they mean the same anyway.

An easier way would to just draw a slope triangle from the two points and count the squares they have. 4 squares going up and 3 squares going to the right = 4/3

Answer:

One. first what you want to do you want to convert 20% into a decimal and a way to do that you need to move a decimal two times to the left. when finding the percent of something you will always move the decimal two times to left

now that you have your 20% into a decimal you will multiply 145 by .20

after you have multiply 245 by .20 you should have gotten 29.00
