Answer:
r = 7
Step-by-step explanation:
60 = -24 + 12r
+24 +24
84 = 12r
84 ÷ 12 = r
7 = r
Check:
60 = -24 + 12r
-24 + 12(7)
-24 + 84 = 60

A jet plane can carry up to 200,000 liters of fuel. It used 130,000 liters of fuel during a flight. What percentage of the fuel capacity did it use on this flight? Do not include the percent sign (%) in your answer.
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.

find the measurement for angle A
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°

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!)

Identify the intercepts of the line. 3x+2y=12
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.
Cerell’s Clothing

Orange
20%
Cerell recorded the percent of her clothing that is Red, Yellow, Blue, or Orange. The results are shown in the table. If Cerell has 145 pieces of clothing, how many pieces of Yellow clothing does she own?
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
Answer: She has 29 pieces of yellow clothing

One standard size for the United States flag is 19 feet
by 10 feet.
What is the ratio of length to width for this flag?
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

You roll a fair number cube and flip a coin at the same time. What is the probability that you roll a 5 and flip a heads?
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%

how many different integers represent the sum of two or more members of the set {-4, -3, -2, -1, 0, 1, 2, 3, 4}?
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}
What is Number system?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}
