Answer:

960

Step-by-step explanation:

12x10x16=1920

1920/2=960

Answer:

59

Step-by-step explanation:

We know that all the angles must add up to 180

so we have

38+2b-20+b-15=180

solve for b

3b+3=180

3b=177

b=59

Answer:

b=59

Step-by-step explanation:

angles in the triangle add up to 180

this would mean that

38 +2b-20 + b-15 = 180

if we simplify this then it would be

3+3b= 180

rearrange

3b = 177

b = 59

Answer:

part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade

part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b

90=25/6(1)+b

90/1=25/6+b

25/6   25/6

and then B= 21.6

Step-by-step explanation: im not sure if i did it right so i would check i havent done this since like the 6th grade like 4 years or so ago lol

Answer:

x = 10

Step-by-step explanation:

7x - 3 + 12x - 7 = 180  because angles on a straight line add up to 180 degrees so we equate this to 180. Now we just simplify and solve to get x on one side! :)

19x - 10 = 180

19x = 190

x = 10

Answer:

Mean: 83.571428571429

Median: 85

Mode: 70

Step-by-step explanation:

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

Answer:

Median 85

Mode 70

Mean 83.571 rounded = 83.6

Answer:

w = 31

Step-by-step explanation:

Since this is a rhombus

==> GFE + FED = 180

2w + w + 87 = 180

==> w = 31

Answer:

2⁴/4² = 1

2 × 3¹ = 6

(4-2)² = 4

Answer:

1. Correct

2. Correct again

3. 4

Step-by-step explanation:

The first one is correct If you need an explanation let me know.

Second one is the same

For the third one since 4-2 is in () you would have to do it first

4-2= 2

Then you will have to do it to the 2nd power which would mean...

2 x 2= 4

So 4 would be your answer.

Hope this helps :)

Step-by-step explanation:

Use the distance formula.

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]x_2=7\\x_1=3\\y_2=-8\\y_1=-2[/tex]

[tex]\sqrt{(7-3)^2+(-8-(-2))^2}[/tex]

=[tex]\sqrt{4^2+(-6)^2}[/tex]

=[tex]\sqrt{16+36}[/tex]

=[tex]\sqrt{52}[/tex]

≈7.2111...

So the answer is B! Hope this helped!

Step-by-step explanation:

Remark

All you need is 2 points that you can rely on as being accurate.

(2,0) should certainly be one of them. I would pick (-1,3) as the other but it is less certain.

Givens

y2 =3

y1 = 0

x2 = -1

x1 = - 2

Formula

m = (y2 - y1)/(x2 - x1)

Solution

m = (3 - 0) / (-1 - - 2)

m = (3 )/ (-1 + 2)

m = 3/1

m = 3

Answer:

Money need to save each month  = $576.92 each month

Step-by-step explanation:

Given:

Amount of money need to save = $125,000 - $35,000 = $90,000

Number of year remain = 18 - 5 = 13 year

Number of months = 13 x 12 = 156 months

Find:

Money need to save each month

Computation:

Money need to save each month = 90,000 / 156

Money need to save each month  = $576.92 each month

Answer:

  y = -0.03x² +12

Step-by-step explanation:

For "tunnel" or "arch" or "bridge" problems, I like to start with the expression ...

  y = 1 - x²

It has a height of 1 and intersects the x-axis at ±1. This can be scaled to give the appropriate height and x-intercepts.

We want the x-intercepts to be ±20, so we can scale this horizontally by a factor of 20:

  y = 1 -(x/20)²

We want the height to be 12, so we can scale it vertically by a factor of 12:

  y = 12(1 -(x/20)²

  y = 12 -12(x²/400)

  y = -0.03x² +12

Answer:

6) -30

7) -5

Step-by-step explanation:

6)

x = 5 y = 3 z = -2

xyz = 5 x 3 x -2 = 15 x -2 = -30

7)

x = 5 y = 3 z = -2

xyz/ 6 = -30/6 = -5

Answer:

Therefore, the exact value of Tan 60 degrees is √3. We can also derive the values of tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way

The value of tan 60° is √3, approximately 1.732.

To calculate the value of tan 60°, we need to use the trigonometric function tangent. Tan 60° represents the ratio of the length of the side opposite the angle to the length of the adjacent side in a right triangle with a 60° angle.

In a 30°-60°-90° right triangle, the length of the opposite side opposite the 60° angle is equal to the square root of 3 times the length of the adjacent side.

The length of the opposite side is √3, and the length of the adjacent side is 1.

Using these values, we can calculate the value of tan 60°:

tan 60° = (opposite side) / (adjacent side) = (√3) / 1 = √3.

Therefore, the value of tan 60° is √3, approximately 1.732.
