Step-by-step explanation:
For this triangle, we have to get the supplementary angle of 122°. 180° - 122° is 58°. We then take 58° and add it to 33°. That is 91°. To find w, we subtract 91° from 180°. That gives us 89°.

A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for π. (PI)
Answers
Your answer should be:
66
Why...?
Simple.
First, you multiply 21 by 22/7. But to make this easier you have to fix in 'improper fraction.' and make it into an improper fraction. Which will become 3 1/7. Now you multiply 21 and 3 1/7. Which will equal 66. So, 66 is your answer.

What is the perimeter of the rectangle?
Answers
Answer:
12
Step-by-step explanation:
Opposite sides of a rectangle share the same side measurements (based on the definition of a rectangle). This means that the perimeter is found as:
P(perimeter)= 2l + 2w
Let:
length (l) = 4
width (w) = 2
Plug in the corresponding numbers tot eh corresponding variables:
P = 2(l) + 2(w)
P = 2(4) + 2(2)
Simplify. First, multiply, then add:
P = (2 * 4) + (2 * 2)
P = (8) + (4)
P = 12
12 will be your perimeter.
~
Check. Since it is given that it is a rectangle, by definition of a rectangle, you will know that opposite sides are congruent, and therefore share the same measurements.
P = 2 + 2 + 4 + 4
P = (4) + (8)
P = 12
12 will be your perimeter.

Answers
A relation is not a function if a vertical line intersects the graph MORE THAN ONCE.
What is a function?A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable).
If a vertical line meets the graph at exactly one point in all directions, the relation is a function. If a vertical line touches the graph more than once, the relationship is NOT a function.
Any vertical line in the plane can only intersect a function's graph once. As a result of the vertical line test, a curve in the plane represents the graph of a function if and only if no vertical line intersects it more than once.
Therefore, If a vertical line intersects the graph MORE THAN ONCE, the relation is not a function.

10.a jar of 70 candies has the following colors: 28 orange, 7 white, 14 brown, and 21 yellow.what is the probability of randomly drawing a candy that is not brown, replacing it, and then drawing a orange candy?
Answers
The total number of candies in the jar is 70, out of which 14 are brown. Therefore, the number of candies that are not brown is 70 - 14 = 56.
To find the probability of drawing a candy that is not brown, replacing it, and then drawing an orange candy, we can use the multiplication rule of probability. According to this rule, the probability of two independent events occurring together is the product of their individual probabilities.
So, the probability of drawing a candy that is not brown on the first draw is 56/70. After replacing the candy, there are still 70 candies in the jar, so the probability of drawing an orange candy on the second draw is 28/70.
Multiplying these probabilities, we get:
(56/70) x (28/70) = 0.16
Therefore, the probability of randomly drawing a candy that is not brown, replacing it, and then drawing an orange candy is 0.16 or 16%.

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units

Answer: 59.3 feet
Step-by-step explanation: we will multiply 11.711.77 ✖ 2.8✖1.8 equal 59.3208 so estimate the 2 can't give something to the 3 so 559.3 , hope my answer is correct
Explanation:
Since you are finding the depth your formula will look like this
11.77= 2.8 x 1.8 x d
(d stands for depth since we don’t know the value)
To solve it you multiply 2.8 and 1.8 which equals 5.04
So now your equation looks like this
11.77= 5.04 x d
Next you divide 11.77 by 5.04 and get

The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area of a trapezoidal base of each prism?
A
units2
B
units2
Answers
Answer:
A = 4 units squared
B = 3 units squared
Step-by-step explanation:
A lot of volume questions can be answered by finding the area of the base, and multiplying it by the height. This does not work with shapes that are not prisms, such as a sphere or cone.
First, we know that both prism's have an area of 24 cubic units. Since we know that in prisms, to find their volume, all we need to do is multiply the height and the area of the base, we can set up an equation. The variable 'x' can represent what we do not know (the area of the base). Equation for A:
A: x * 6 = 24
Now, we need to figure out what multiples by 6 to get to 24. To do this, we can divide 24 by 6. We get:
A: x = 4
Using the same reasoning used in figure A, this is the equation for B:
B: x * 8 = 24
Now, we need to figure out what multiplies by 8 to get to 24. To do this, we can divide 24 by 8. We get:
B: x = 3
* * NOTE: THE 'x' does not have the same value in both situations. We used x to represent the area of the base in both situations. * *
