Answer:
z = 45 (it is the same angle as x)
y and u = 135
Step-by-step explanation:
45 + 45 = 90
360 - 90 = 270
270/2 = 135
CHECK YOUR WORK:
135 + 135 + 45 + 45 = 360
270 + 90 = 360
360 = 360
Answer:
z = 45
y = 135
u = 135
Step-by-step explanation:
Vertically opposite angles are equal so x and z must be the same.
A circle is 360 degrees so
360 - (45 + 45) = 270
270 / 2 = 135 degrees
This means that y and u must both be 135 as they too are vertically opposite.
4g^2 - 32g = 0 into polynomial? PLEASE ANSWER THIS QUICKLY IM BEGGING
Answer:
g = 8
Step-by-step explanation:
32 g = 4 g squared if you move it over, so divide both sides by 1 g and you get 4g = 32, so g = 8

if (a/b) =(9/7)^-3 ÷(3/7)^1, then find the value of (a/b)^2
Answer:
decimal = 1.20527
Step-by-step explanation:
[tex]\frac{a}{b} = (\frac{9}{7})^{-3} \div (\frac{3}{7})^1[/tex]
[tex]=(\frac{7}{9})^3 \times \frac{7}{3}\\\\[/tex]
[tex](\frac{a}{b})^2 = ((\frac{7}{9})^3)^2 \times (\frac{7}{3})^2\\\\[/tex]
[tex]= \frac{7^6 \times 7^2}{9^6 \times 3^2}\\\\= \frac{7^8}{9^6 \times 9}\\\\=\frac{7^8}{9^7}\\\\=\frac{7^7 \times 7}{9^7}\\\\= 7 \times \frac{7^7}{9^7}\\\\= 7 \times (\frac{7}{9})^7[/tex]
[tex]=\frac{5764801}{4782969}[/tex]

A circular flower bed is 23 m in diameter and has a circular sidewalk around it that is 4 m wide. Find
the area of the sidewalk in square meters. Use 3.14 for it.
The area of the sidewalk is m2.
Answer:
Step-by-step explanation:
Think of this as a circle in a larger circle, and the area thats only taken by one circle is the area of the path.
One Circle has area 11.5, while the other has a area of 15.5
The area of the smaller circle is 11.5^2*pi or 132.25pi
The area of the larger circle is 15.5^2*pi or 240.25pi
The area of the path is 108pi or 339.12
What is the measure of x? I'm not sure if its c. Please help!
Answer:
[tex]\text{(C) }110^{\circ}[/tex]
Step-by-step explanation:
The angle marked [tex]110^{\circ}[/tex] and the angle marked by [tex]x[/tex] are vertical angles (on opposite sides of the intersection of two lines). All vertical angles are equal, therefore [tex]x=\boxed{\text{(C) }110^{\circ}}[/tex].
Javed is building a birdhouse in the shape of a triangular pyramid. He drew the net for his birdhouse and labeled the dimensions. The base is an isosceles triangle with two side lengths of 20 cm. How much wood will Javed need for the birdhouse?
Answer:
See attachment
Step-by-step explanation:
Required
How much wood needed (i.e. the surface area)
The question is incomplete, as the net of the triangular prism is not given. So, I will answer with the attached net.
To calculate the surface area, we simply calculate the area of each face of the net.
The area of the net is as follows:
Area= 2 * Area of Triangle + 2 * Area of 2 Congruent Rectangles + Area of the third rectangle
So, we have:
[tex]Area = 2 * \frac{1}{2} * 6 * 5 + 2 * 8 * 7 + 8 * 6[/tex]
[tex]Area = 30 + 112 + 48[/tex]
[tex]Area = 190cm^2[/tex]

Jennifer hit a golf ball from the ground and it followed the projectile ℎ(t)= −15t^2+100t, where t is the time in seconds, and ℎ is the height of the ball.
a. Find the highest point that her golf ball reached algebraically.
b. How many seconds will the ball reach the maximum height?
c. Find a reasonable domain and range for this situation.
Answer:
Step-by-step explanation:
In order to find the max height the ball reached, we have to complete the square on that quadratic. That will also, conveniently so, give us the number of seconds it will take the ball to reach that max height, that answer to part b. Let's begin to complete the square. Normally, you would move the constant over to the other side of the equals sign, but there is no constant here. The next step is to get the leading coefficient to be a 1, and ours right now is a -15. So we have to factor it out. Here's where we start the process of completing the square.
[tex]-15(t^2-\frac{20}{3}t)=0[/tex] Next step is to take half the linear term, square it, and add it to both sides. Our linear term is 20/3. Half of 20/3 is 20/6, and 20/6 squared is 400/36.
[tex]-15(t^2-\frac{20}{3}t+\frac{400}{36})=0+???[/tex] Because this is an equation, what we add to the left side also has to be added to the right. BUT we didn't just add in 400/36, because we have that -15 out front as a multiplier that refuses to be ignored. What we actually added in was -15(400/36):
[tex]-15(t^2-\frac{20}{3}t+\frac{400}{36})=0-\frac{500}{3}[/tex]
The reason we do this is to create a perfect square binomial on the left which will serve as the number of seconds, h, in the vertex (h, k), where h is the number of seconds it takes the ball to reach its max height, k. Simplifying both sides then gives us:
[tex]-15(t-\frac{20}{6})^2=-\frac{500}{3}[/tex] Finally, we will move the right side over by the left and set the quadratic back equal to h(t):
[tex]h(t)=-15(t^2-\frac{20}{3})^2+\frac{500}{3}[/tex] and from that you can determine that the vertex is [tex](\frac{20}{3},\frac{500}{3})[/tex].
The answer to a. is vound in the second number of our vertex: k, the max height. The max of the golf ball was 500/3 feet or 166 2/3 feet.
Part b is found in the first number of the vertex: h, the number of seconds it took the golf ball to reach that max height. The time it took was 3 1/3 seconds.
Part c. is to state the domain (the time) and the range (the height) of the ball.
Domain is
D: {x | 0 ≤ x ≤ 3 1/3} and
Range is
R: {y | 0 ≤ y ≤ 166 2/3}

Answer:
A.) 4 x (y + 7)
Step-by-step explanation:
4 times means that you are going to be multiplying something by 4. It says 4 times the sum of y and 7. This means that you are going to multiply whatever y and 7 equal by 4. Sum means addition. So that's going to be that you are multiplying what the combined total of y and 7 is by 4.

Answer:
Step-by-step explanation:
6 is the maximum value
so the inequality is
x ≤ 6
Answer:
Part A:
The inequality would be less than or equal to, since the temperature isn't greater than 6, but the phrase doesn't get rid of the possibility that it could be less than 6. Hope that makes sense!
Also, the inequality sign would be: ≤
Part B:
For the graph, you woulld plot a closed circle on the 6, with an arrow heading left.

I need help with this question
Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees

What's for Lunch2
Marcia Amidon Lusted
Zachary Maxwell was tired of trying to explain to his parents why he wanted to bring lunch to school
instead of eating hot lunch. They couldn't understand why he didn't want to eat the gourmet food
described on the school's online menu, which sounded both nutritious and interesting. Zachary just
couldn't convince them that the food wasn't as great as it sounded. So in the fall of 2011, he began
sneaking a small video camera into the cafeteria at his school, to show his parents what the lunches
were really like. Six months and 75 school lunches later, Zachary made a documentary film about his
lunch called Yuck A 4th Grader's Short Documentary About School Lunch
Did the student who made this film provide an objective opinion? Did that affect the quality of the film?

Answer:
The integers could be 21 and 22
or -22 and -21
Step-by-step explanation:
If two integers are consecutive, then it means that their difference is just 1
if we have the initial value as x , then the other value could be x-1 or x + 1
let us go with x-1
So the product here is;
x(x-1) = 462
x^2-x = 462
x^2 -x -462 = 0
x^2 -22x + 21x - 462 = 0
x(x-22) + 21(x-22) = 0
(x + 21)(x-22) = 0
x = -21 or x = 22
If x = -21
x -1 = -21-1 = -22
if x = 22
x -1 = 22-1 = 21
