Answer:

32 orange marbles.

Step-by-step explanation:

First set up the proportion given in the problem, since it states that there are three red marbles for every four orange marbles. The ratio between them is 3:4.

This means that you can multiply the given amount of red marbles by 4/3 to find the amount of orange marbles and the given amount of orange marbles by 3/4 to find the amount of red marbles. Because there are 3 red marbles for every 4 orange marbles.

You can divide 32 by 3 to find the factor which is 8 and multiply by 4 to get 32. Because 8 × 3 = 24,

and 8 × 4 = 32.

It can also be thought of as fractions because the proportion is a factor which means that you can multiply and divide to get to a certain value.

So:

3/4 = 24/O

Red marbles / orange marbles = red marbles / orange marbles.

(cross multiply ; numerator times denominator, and denominator times numerator; numerator is the top number, and the denominator is bottom number of a fraction).

3O = 96

÷3 ÷3

O [orange marbles] = 32

Answer:

c

Step-by-step explanation:

It is given that the line AB is Perpendicular Bisector of IK. It means the line AB is perpendicular on IK and the point J divides the line IK in two equal parts.

If a line is bisector of another line, then the point of intersection divides the second line is two equal parts.

Therefore the distance between intersection point and the endpoints of the second line are the same.

The intersection point is J and the end points of IK are I and K. So, we can say that IJ = JK.

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:

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:

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: 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!)

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.
