explanation:
first, it’s important to remember that all angles of a triangle equal 180 degrees. so, subtract 50 from 180 = 130. that means that the last two angles combined equal 130. next, it’s important to remember that a straight line is equal to 180 degrees. since you know that 120 out of that 180 degrees is shown, 180-120 = 60. that means that the bottom angle of the triangle is 60. 60+50 = 110. 180-110= 70. so, that last angle is equal to 70 degrees. hope this helped!!

Find the circumference and area of a circle A with a diameter of 26 inches.
Please I need the answer ASAP. Thank you very much.
Answers
Answer:
Circumference: 81.681 in; Area: 530.929 in
Step-by-step explanation:
To find circumference we use the formula pi x diameter. Which in this case is pi x 26 in, or approximately 81.681 in.
For the area, we use pi x r^2. r = 1/2 d, so r = 13in. Therefore, the area is equal to 169 x pi in, which is about 530.929 in.

Find an ordered pair (x,y) that is a solution to the equation.
5x+y=6
Answers
Answer:
(0,6) and (1.2 , 0)
Step-by-step explanation:
5x + y = 6
if we take x=0
5(0) + y = 6
y = 6 ; so, one of the solution is (0,6)
if we take y=0
5x + (0) = 6
5x = 6
x = 6/5 = 1.2 ; so, the other solution is (1.2 , 0)
But basically, you can find other solutions of the equation if you do this:
5x + y = 6
5x = (6 - y)
x = (6 - y) / 5 ; so if you use whatever number of y, you will find the rigth solution for x.
and you can do the opposite too:
5x + y = 6
y = 6 -5x ; with this, you can use whatever number of x, and find the right y.

Answers
The maximum amount of water that the bottle can hold is 2251.77 cubic inches.
What is volume?
A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes.
To find the maximum amount of water that the bottle can hold, we need to find the volume of the bottle.
The bottle is in the shape of a cylinder with a height of 12.5 inches and a radius of 8.5/2 = 4.25 inches.
The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.
Substituting the values, we get:
V = π(4.25)²(12.5)
V = 2251.77 cubic inches
Therefore, the maximum amount of water that the bottle can hold is 2251.77 cubic inches.

The length of a rectangle is 3 yards less than 5 times the width. If the perimeter is 102 yards, find the length and the width of the rectangle.
Answers
Answer:
Width = 9 yards, length = 42 yards
Step-by-step explanation:
Perimeter = 2xlength + 2xwidth. Let's call length L and width W. The question also states that L = 5W-3. Therefore, 102 = 2x (5W-3) + 2W. Then, 102 = 12W - 6. 108 = 12W, so W = 9 yards. Since L = 5W - 3, we get 45-3 = 42 yards.

Step-by-step explanation:
calculator
Answer:
Robin can clean 9828 rooms in 9 days
Step-by-step explanation:
Since Robin can clean 727272 rooms in 666 days, we can find how many rooms she can clean in 1 day by dividing 727272 by 666
number of rooms cleaned by Robin in 1 day = 727272 rooms/666 days = 1092 rooms/day
We can then find how many rooms she can clean in 9 days by multiplying 1092 by 9
1092 rooms/day * 9 days = 9829 rooms
Using the following data set calculate the mean 9,14,14,9,20,6,8,19,17,13,9
Answers
Answer:
12.54
Step-by-step explanation:
When finding the mean, first you add all the numbers in the data:
9+14+14+9+20+6+8+19+17+13+9=138
And then you divide it by the following numbers in the set. In this data set, since there are 11 numbers, you would divide 138 by 11.
138\11=12.5454545
So the answer would be 12.54 if your rounding to the nearest hundred. If your rounding it by a whole number, it would be 13.
Plastic parts manufactured using an injection molding process may exhibit one or more defects, including sinks, scratches, black spots, and son on. Let x represent the number of defects on a single part, and suppose the distribution of x is as follows: x: 0 1 2 3 4 p(x): 0.79 0.09 0.05 0.04 0.03 What is the expected value, E(X), for the number of defects on a randomly selected plastic part
Answers
Answer:
The expected value for the number of defects on a randomly selected plastic part is 0.43.
Step-by-step explanation:
We have the following probability distribution:
P(X = 0) = 0.79
P(X = 1) = 0.09
P(X = 2) = 0.05
P(X = 3) = 0.04
P(X = 4) = 0.03
What is the expected value, E(X), for the number of defects on a randomly selected plastic part?
Each value multiplied by its probability. So
[tex]E(X) = 0.79*0 + 0.09*1 + 0.05*2 + 0.04*3 + 0.03*4 = 0.43[/tex]
The expected value for the number of defects on a randomly selected plastic part is 0.43.
