Answer:
12.125
Step-by-step explanation:
Angles 10x - 22 and 6x + 8 are linear pair.
10x - 22 + 6x + 8 = 180
10x + 6x + 8 - 22 = 180
16x - 14 = 180
16x = 180 + 14
16x = 194
x = 194 / 16
= 97 / 8
x = 12.125
14 and 15 please thank you
Problem 14
Answer: They bought too much sand-----------------------
Explanation:
Because the sandbox is a rectangular prism, aka a block, we multiply the length width and height to get the volume.
Volume = length*width*height = 6*5*1.2 = 36
The volume of the sandbox is 36 cubic feet.
The customer bought 40 cubic feet of sand, which exceeds the volume we computed earlier. The customer bought too much sand.
If it was a choice of buying too much or too little, I think it's better to go overboard just so you don't have to return to the store. The extra amount of sand (40-36 = 4 cubic feet) can possibly sold or donated at a later time.
==========================================================
Problem 15
Answers:The equation could be 306.52 = 19.4h or 19.4h = 306.52Either equation mentioned solves to h = 15.8; so the height of the prism is 15.8 meters-----------------------
Explanation:
The rectangular prism formula to calculate the volume is
Volume = length*width*height
Note that the portion "length*width" can be replaced with "base area", because the base area is a rectangle.
So we can have this alternative formula
Volume = (base area)*height
If we know the area of the floor, and multiply by the height of the wall, then we can calculate the volume of a room like this. In this case, the floor is 19.4 square meters in area. The overall room is 306.52 cubic meters. We'll let h be the height of the wall. Use algebra to solve for h
Volume = (base area)*height
306.52 = 19.4h .... is one equation to set up
19.4h = 306.52
h = 306.52/19.4
h = 15.8
We divide both sides by 19.4 to undo the multiplication going on.
The height of the prism is 15.8 meters.
What is the value of 8+23×5?
Answer: 123
Step-by-step explanation:
Value of 8+23×5 is 123.
What is PEDMAS Rule?PEDMAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on division & multiplication and at last addition and subtraction.
Given
8+23×5
We have to perform multiplication as per the PEDMAS rule
= 8 + 115
Now we have to perform addition
= 123
Hence, value of 8+23×5 is 123.

What is the complementary angle of:
- 6 degrees
- 21 degrees
Answer:
The complementary angle of
-6 degrees is 84
-21 degrees is 69
Step-by-step explanation:
to solve this question complementary angles sum up to 90 degrees, when 2 angles come together to form a 90 degree right angles they are complementary.
90-6= (84)
90-21=(69)

B) Black grapes cost more per pound than green grapes.
Step-by-step explanation:
If you look at the graph at 1, the cost of 1 pound of back grapes would be $2.00.
If you were to plug 1 into the equation of green grapes, 1 pounds of green grapes would be $1.50, which is less than $2.00

A simulation is done to represent kicking 5 field goals in a single game with a 72% probability of making each one. A 1 represents
making the kick and a 0 represents missing the kick.
result
Based on results, estimate the probability that 3 or more kicks are made
Answer: 60%
From what I learned, take this example from a pair of dice: If you want to know the probability of getting 3, you take the event (the 3 or the thing you want to know) and divided it by the outcome (or total)
in other words : probility = event(3)/outcome(6)

Answer:
VVVVVVVVVVVV
Step-by-step explanation:

The scatter plot diagram that represents the data that is shown in the given table is; Attached below
How to draw a scatter plot diagram?We are told that;
the x-axis represents the beginning balance in thousands of dollars.
the y-axis represents the change in the bank account by hundreds of dollars.
Now, this means the values on the x-axis in plotting order from left to right with their corresponding y-values are;
x - values = 6, 4, 3, 1, 8, 3, 4, 5
y - values = 6, 5, 2, 5, 4, 8, 2, 3
Thus, to plot the scatter diagram, we will enter the corresponding x and y coordinate values which are seen in the scatter diagram attached.
