Answer:

Step-by-step explanation:

All the angles in a triangle have to add up to 180 degrees.

#17.)

45+50=95

180-95=85

x=85

#18.)

This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.

180-118=62.

25+62=87

180-87=93

x=93

#21.)

For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.

180-108=72

x+x+2+72=180

2x+74=180

2x=106

x=53

Answer

#17=85

#19=93

#21=53

Step-by-step explanation:

Check boxes 1 and 4 (these two are true!).

1. Quadrant I is the top right quadrant on the graph. All values for x and y are positive in quadrant 1. Quadrant III is the bottom left and both coordinates (x,y) would always be negative.

4. Multiplying a number by itself is the same as squaring that number or raising it to the power of 2. In all cases, squaring a number results in a positive value. Therefore, no matter if the coordinates are positive or negative, the new coordinates will both be positive after being multiplied by themselves. This will result in the new coordinates being in Quadrant I.

The simplest form of (4a + 8b) / 12 is (a + 2b) / 3.

Given is an expression (4a + 8b) / 12, we need to simplify it in simpler form,

To simplify the expression (4a + 8b) / 12, you can divide both the numerator and the denominator by their greatest common divisor (GCD) to reduce the fraction to its simplest form.

First, let's find the GCD of 4 and 12. The factors of 4 are 1, 2, and 4, and the factors of 12 are 1, 2, 3, 4, 6, and 12.

The largest number that appears in both sets of factors is 4, so the GCD of 4 and 12 is 4.

Dividing both the numerator and the denominator by 4, we get:

(4a + 8b) / 12 = (4(a + 2b)) / (4 x 3)

Canceling out the common factor of 4:

(4(a + 2b)) / (4 x 3) = (a + 2b) / 3

Therefore, the simplest form of (4a + 8b) / 12 is (a + 2b) / 3.

What is the simplest form of 4a+8b over 12

Answer:

108

Step-by-step explanation:

So, to start, we can calculate the fuel used in March by using the following equation:

(40x240)/100

Which is 96. So the furnace burned 96 gallons of fuel in March and was left with 144 gallons. Now we need to find out how much of its remaining fuel it burned in April, so we use this:

(25x144)/100

Which is 36. So it burned another 36 gallons of fuel in April, leaving it with 108 gallons still in the tank.

Answer:

4/9 loads

Step-by-step explanation:

From the line plot, the kind of laundry detergent that has 4 bottles is the one that contains 8 cups.

Therefore, Natalie buys a bottle of detergent with 8 cups.

1 bottle = 8 cups

Natalie uses 1/8 cup for each load of laundry

Therefore:

Number of laundry Natalie can do with 1 bottle of laundry detergent = 8/18

=4/9 loads

hope this helped you

Answer: 14 Loads

Explanation: There are lots of unnecessary data here. The important thing is the fact that Jada buys one of the bottles of laundry with the fewest bottles on the shelf and that she uses 1/8 cup in each load of laundry. Look at the line plot. The bottle of laundry with the least amount is 14 (it has the fewest amount of x).

1/8=1 Load

8/8=8 Loads, 1 Cup

?/8=? Loads, 14 Cups

__________________________________________________________

Let's try out a few numbers:

40/8=5 Loads, 5 Cups

96/8=12 Loads, 12 Cups

112/8=14 Loads, 14 Cups

1. The lower quartile is always the left side of the box.

2. The IQR is Quartile 1 minus Quartile 2, so you could subtract the number at the right of the box with the left.

3. The range is the highest number minus the lowest number. (The numbers that stretch out all the way til the lines stop)

4. The median is the line in the middle of the box.

5. The upper quartile is right of the box. (the vertical line)

6. The Lower Quartile Is Always Smaller Than The Upper Quartile.

7. The number all the way to the right of the number line.
