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}

Answer: that is a 45 degree angle

Step-by-step explanation: 90 / 2 is 45

Answer:

∠ A = 44°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + 59 + x + 51 + 84 = 180, simplify

2x + 194 = 180 ( subtract 194 from both sides )

2x = - 14 ( divide both sides by 2 )

x = - 7

Thus

∠ A = x + 51 = - 7 + 51 = 44°

Given:

Capacity of jet plane = 200,000 liters of fuel

Fuel used during flight = 130,000 liters

To find:

The percentage of the fuel capacity it uses on this flight.

Solution:

According to the question, we need to find 130,000 is what percent of 200,000.

[tex]\text{Required percentage}=\dfrac{\text{Fuel used during flight}}{\text{Capacity of jet plane}}\times 100[/tex]

[tex]\text{Required percentage}=\dfrac{130000}{200000}\times 100[/tex]

[tex]\text{Required percentage}=65[/tex]

Therefore, the jet plane uses 65 percent of fuel capacity during flight.

Answer:

The x-intercept is  ( 4 , 0 ) .

The y-intercept is  ( 0, 6 ) .

Step-by-step explanation:

his is the formula for a linear equation in standard form. This is the easiest equation for finding the intercepts. To find the x- and y-intercepts, substitute  0  for one variable, and solve for the other.

X-intercept: value of  x  when  y = 0

Substitute  0  for  y  and solve for  x .  

3 x + 2 ( 0 ) = 12  

3 x = 12  

Divide both sides by  3 .

x = 12 /3

x = 4  

The x-intercept is  ( 4, 0 ) .

Y-intercept: value of  y  when  x= 0

Substitute  0  for  x  and solve for  y .

( 0 ) + 2 y = 12

2 y= 12

Divide both sides by  2 .

y = 12 /2  

y = 6

The y-intercept is  ( 0 , 6 ) .

These are the intercepts.

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:

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:

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

Step-by-step explanation:

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
