Examine the diagram. A triangle. Angle B is the exterior angle to angle A. The other 2 exterior angles are 100 degrees and 127 degrees. Follow these steps to apply what you have learned about the angles of a triangle. Find m∠B : 100° + 127° + m∠B = 360° Then, find the measure of angle A. Which is the measure of angle A? 133° 53° 47° 80°

Answer:

15

Step-by-step explanation:

Equation to remember:

Length · Width · Height = Volume

LWH = V

-------------------------------------------------

In this word problem, you can find that we're missing the height aspect of the equation. Your equation would look something like this:

[tex]12 * 10 * h = 1800[/tex]

-------------------------------------------------

Work:

[tex]12 * 10 * h = 1800\\\\120h = 1800\\\\\frac{120h}{120} = \frac{1800}{120}\\\\h = 15[/tex]

-------------------------------

As you can see, the height of our rock is 15cm.

I hope this helped!

Answer:

D - 8

Step-by-step explanation:

V= 4/3 x pie x radius to the 3rd power

V = 4/3 x 3.14 x 1.25 to the 3rd power

V = 4/3 x 3.14 x 1.953125

V = 4.18666666667 x  1.953125

V = 8.17708333333

Answer:

A'' (-1,5)

B'' (0,1)

C'' (-3,-1)

Step-by-step explanation:

For A,

Step 1, (2,2) change to (-2,2), cuz if reflect in y-axis, positive value of x will change to negative value of x, negative value of x will change to positive value of x.

Step 2, (-2,2) change to (-1,5), cuz we add up the 1 to x-value, add up 3 to y value.

For B,

Step 1,

(1,-2) to (-1,-2)

Step 2,

(-1,-2) to (0,1)

For C,

Step 1,

Step-by-step explanation:

Answer:

30.99 inHg.

Step-by-step explanation:

First, subtract how much the pressure dropped on Tuesday from Monday's reading. 30.01 inHg - 0.34 inHg = 29.67 inHg

Then, add how much the pressure climbed on Wednesday to Tuesday's reading. 29.67 inHg + 1.32 inHg = 30.99 inHg

Answer:

The barometric pressure reading for Wednesday was 31.01inHg. This can be calculated by subtracting 0.34inHg from the pressure reading on Monday (30.01inHg) and then adding 1.32inHg, which results in 31.01inHg.

Answer:

w = 7, and w = 8 is correct

Step-by-step explanation:

1. Why 5 does not work

a. Substitute 5 into the equation

5w-10>20 --> 5(5) - 10 > 20

b. Solve the equation

Remember Pemdas:

P- Parentheses First

E- Exponents Second

M- Multiplication Third

D- Division Fourth

A- Addition Fifth

S- Subtraction Sixth

We are not working with Exponents and Parentheses, but we are working with the rest.

Since there is no P and E, that means that multiplication is first

5(5)-10>20 - 5(5) = 5 x 5 = 25

Now all is left is to subtract:

25 - 10 = 15

15 > 20 Is not true.

2. Why 6 does not work

a. Substitute

5w-10>20 --> 5(6) - 10 > 20

b. Solve

5(6) = 5 x 6 = 30

30 - 10= 20

20 > 20 is not true

Just like you are not greater than yourself, 20 can not be greater than its own self.

3. Why 7 and 8 work (7a, 7b is 7; 8a, 8b is 8)

7a. Substitute

5w-10>20 --> 5(7) - 10 > 20

8a. Substitute

5w - 10 >20 --> 5(8) - 10 > 20

7b. Multiply and subtract

5(7) = 5 x 7 = 35

35 - 10 = 25

25 > 20

25 is greater than 20

8b. Multiply

5(8) = 5 x 8 = 40

40 - 10 = 30

30 > 20

30 is greater than 20

Hereby, w = 7, and w = 8

Hope this helps

Answer:

x - 5 ≤ 0,  x  + 13 ≥ 0  

Step-by-step explanation:

All numbers such that x≤5.

x - 5 ≤ 0

All numbers such that x≥−1.3.

x  + 13 ≥ 0  

The absolute value equations in the form of  |x-b|= c(where b is a number and c can be either a number or an expression) that has the following solution set

all numbers such that x ≤ 5 and all numbers such that x ≥ -1.3 will be x -5 ≤ 0 and x + 1.3 ≥ 0.

Isolate the absolute number on one side of the equation to solve an equation containing the absolute value.

Then, resolve both equations by changing their respective contents to the positive and negative values of the variable on the other side of the equation.

In another word, the absolute value equation is the equation that has a real absolute value not imaginary and not binary.

In the mode function, it could be two values if the mode is going negative or positive.

Given that the equation |x-b| = c and constraint is

all numbers such that x ≤ 5

all numbers such that x ≥ -1.3

so by substituting we will get x -5 ≤ 0 and x + 1.3 ≥ 0.

The third angle measures 70°

It is an acute triangle.

i know that because eat triangle is 180°, so if we subtract 40° and 70° from 180°, we get 70°, meaning the three angles in the triangle are 40°, 70°, and 70°. Because all of the angles are under 90°, we know that it is an acute triangle.

The answers are (d) The third angle measures 90° and (e) All sides have different lengths.

To measure the center, median is the best method.

The value that divides the mathematical numbers or expressions in half is known as the median. The middle data point is known as the median value.

To find the median:

First, organize the data points in ascending order before calculating the median.

The middle number on the list is the median if the number of observations is odd.

Take the value of the (n+1)/2-th term, where n is the total number of observations, to determine this.

Otherwise, the median is the simple average of the middle two figures if the number of observations is even.

Therefore, the median is the best method to find the measure of the center.

Answer:

a= 40, b= 50, c= 115

Step-by-step explanation:

a-

There is a theorem for a that gives you the answer:

Vertical angles are congruent

If the vertical angle of a is 40°, then a is also 40°.

That is what the theorem says.

b-

This one is kind of difficult, but let me break down the steps.

Now you already know that a is 40°, and the other angle besides b is a right angle because it shows a square, or 90°.

And now you need to know another law:

Every single triangle's angle adds up to 180°.

Now, this is basically a subtraction problem.

If two of the angles are there, and you know that all of the angles of a triangle add up to 180°, then you just need to know what 90 + 40 + x = 180 is

90 + 40 = 130

130 + x = 180

Subtract 130 from both sides

130 + x = 180

-130        -130

x=50, which means that all of the angles add up to 180°, or following the law.

c-

This one is different as well.

You can very clearly see that it is a straight line that crosses 65° and c.

There is one more law as well:

A straight line is 180°.

If that line that 65 degrees and c sits on is straight, that means that-

65 + x = 180, or

180 - 65 = x

180-65 = 115, and c=115.

It also follows that law; 115 + 65 = 180, which means that it is correct.

Hope this helps :)

The expressions that represent the area of the quadrilateral shown is first and last options.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given is a quadrilateral.

This can be divided into known quadrilaterals to find the area.

This can be done in two ways as shown in the image below.

Area of rectangle/square = Length × Width

Area of triangle = [tex]\frac{1}{2}[/tex] × base × height

As shown in the first figure,

Area of the quadrilateral ADGH = Area of rectangle ABCD - Area of ΔABH - Area of ΔGHE - Area of square GECF - Area of ΔFGD.

Area = (8 × 8) - ([tex]\frac{1}{2}[/tex] × 8 × 2) - ([tex]\frac{1}{2}[/tex] × 2 × 4) - (2 × 2) - (([tex]\frac{1}{2}[/tex] × 6 × 2)

This is the first option.

As shown in the second figure,

Area of quadrilateral GFBE = Area of ΔGDF + Area of ΔBCF + Area of rectangle ABCD + Area of ΔABE

Area = ([tex]\frac{1}{2}[/tex] × 8 × 2) + ([tex]\frac{1}{2}[/tex] × 2 × 4) + (6 × 4) + ([tex]\frac{1}{2}[/tex] × 6 × 2)

This is the last option.

Hence the area of the quadrilateral can be either first or last option.
