Answer:
2880 m
Step-by-step explanation:
find the area under the graph. i have split it into 3 areas A, B and C
A (trapezium) = 1/2 x (150 + 160) x 15 = 2325
B (trapezium) = 1/2 x (15 + 6 ) x (160 - 110) = 525
C (triangle) = 1/2 x 10 x 6 = 30
total = 2325 + 525 + 30 = 2880

Answer:
The measure of U is 106 degrees
Step-by-step explanation:
Ok, so first let's solve for x (noting that the interior angles add up to 360)
W=90 (right angle) V = 11x+1 X=75 U=12x+10
now let's put them into equation format:
90 + 11x + 1 + 12x + 10 + 75 = 360
combine like terms:
90 + 1 + 10 + 75=176 11x + 12x=23x
we get: 23x + 176=360
solve: -176 -176
23x = 184
/23x /23x
x = 8
Now we have to solve for U:
12(8) + 10 = ?
96 + 10 = 106
Thus, it is 106 degrees

Answer:
As shown in picture:
A(-4, 1)
Z(-2, 3)
P(3, -4)
The length of AZ is calculated by:
L = sqrt((-4 - -2)^2 + (1 - 3)^2) = 2.83
The length of AP is calculated by:
L = sqrt((3 - -4)^2 + (-4 - 1)^2) = 8.60
THe length of ZP is calculated by:
L = sqrt((3 - -2)^2 + (-4 - 3)^2) = 8.60
=>Perimeter of triangle AZP is calculated by:
P = AZ + AP + ZP = 2.83 + 8.60 + 8.60 = 20.3
Hope this helps!

find the area of each Arc. Use the 3.14 as the value of pi. Round your answer to the nearest tenth. Label unit
Answer:
18.8 m²
Step-by-step explanation:
The area of a sector is given by the formula ...
A = (1/2)r²θ . . . . . . . r is radius, θ is the central angle in radians
To convert an angle in degrees to one in radians, multiply by π/180°.
Your 135° sector has an area of ...
A = (1/2)(4 m)²(135°)(π/180°) = 6π m²
A ≈ 18.8 m²
A six-sided number cube is rolled two times. What is the probability of rolling a 4 both times?
Answer: 1/36
Explanation: In this problem, we're given that a number cube is rolled twice and we're asked to find the probability of rolling a 4 and a 4.
It's important to understand that the two rolls of the number cube are independent events because the results of one role does not affect the results of the other roll.
To find the probability of two independent events, we first find the probability of each event, then we multiply the probabilities.
So let's first find the probability of rolling
a 4 with our first role of the number cube.
We can find the probability of an event using the following ratio:
number of favorable outcomes over total number of outcomes
Since there's only one way to roll a 4 and there are six possible outcomes 1, 2, 3, 4, 5, and 6, the probability of rolling a 4 is 1/6.
Next, we find the probability of rolling a 4 with our second roll of the number cube, which would also be 1/6.
Now, to find the probability of rolling a 4 and a 4,
we simply multiply the probabilities.
Now multiply 1/6 x 1/6 by multiplying across the top and bottom.
This gives us 1/36.
So the probability or likelihood of rolling a 4 two times in a row is 1/36.
A company is designing a new cylindrical water bottle. The volume of the bottle will be 121 cmcubed. The height of the water bottle is 7.6 cm. What is the radius of the water bottle? Use 3.14 for pi.
Answer:
The radius of the water bottle is 2.25 cm
Step-by-step explanation:
The water bottle is said to be cylindrical, so its volume can be expressed as the volume of a cylinder.
Volume of a cylinder V = πr^2 h
Where;
h = height
r = radius
Making the radius the subject of formula;
r^2 = V/πh
r = √(V/πh)
Given:
Volume V = 121 cm^3
height h = 7.6 cm
π = 3.14
Substituting the given values;
r = √(121/(3.14×7.6))
r = 2.25 cm
The radius of the water bottle is 2.25 cm

Select all that are like radicals to /11. (i’ll give you brainliest answer)
Answer: B and E
Step-by-step explanation:
x√11 and -6√11 are the like radicals of √11.
What is Radicals?Radicals are expressions which includes root of any degrees like square root, cube root or generally any nth root.
Usually radical denotes the square root and cube root.
There are three different components for the radical namely radicand, symbol and degree.
Like radicals are radicals whose degree and radicands are the same. Radicand is the number inside the root and the degree of the root is the times that radicand is multiplied to itself.
So these two components must be the same for two radicals to be like radicals.
This does not depend on whatever coefficients the radicals have.
Here, x√11 and -6√11 are the like radicals of √11.
Hence, by the definition of like radicals, x√11 and -6√11 are the like radicals of √11.

What is the slope-intercept equation of the line below?
Answer:
y = -x-2
Step-by-step explanation:
We are given a slope of -1 and the y intercept of -2
The slope intercept form of the equation for a line is
y = mx+b
where m is the slope and b is the y intercept
y = -1x +-2
y = -x-2
Answer:
y=-x -2
Step-by-step explanation:
Slope-intercept form is
y=mx+b
where m is the slope and b is the y-intercept
We know that the slope is -1. We also know that the y-intercept is (0, -2). For this form, we can disregard the 0, and say the y intercept is just -2.
So, m is -1, and b is -2. Substitute the values into the equation.
y=mx+b
y=-1x+-2
Simplify
y= -x -2
This is the equation of the line in slope-intercept form.

This is area of a circle correct?
The formula is PI x radius squared.
3.14 x the radius, which is 5, squared
I am re-editing this
so sorry the answer is actually 78.54
The reason why it is 78.54 is that you need to square the radius before multiplying with PI.
Step-by-step explanation:
okay, so the area of a circle can be found with the formula πr^2
this means you have to square the radius of the circle and multiply it by pi to find your answer.

c. A vendor at a street fair sells popcorn in cones, all of height 9 inches. The sharing-size cone has 3 times the radius of the skinny-size cone. About how many times more popcorn does the sharing cone hold than the skinny cone?
Answer:
Sharing cone holds 9 times more popcorn than a skinny cone.
Step-by-step explanation:
Height of each cone = 9 inches
Radius of the sharing size cone = 3 times radius of the skinny size cone
Let the radius of skinny size cone = r
Then radius of the sharing size cone = 3r
Volume of the sharing size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]
= [tex]\frac{1}{3}(\pi )(3r)^{2}(9)[/tex]
= 27πr²
Volume of the skinny size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]
= [tex]\frac{1}{3}(\pi )(r)^{2}(9)[/tex]
= 3πr²
Ratio of the volumes = [tex]\frac{\text{Volume of sharing size cone}}{\text{Volume of skinny size cone}}[/tex]
= [tex]\frac{27\pi r^{2}}{3\pi r^{2} }[/tex]
= 9
Therefore, sharing cone holds 9 times more popcorn than a skinny cone.
