In right triangle ABC, A = 42°. Find the measure of B which is the other non
right angle.
A=42
C=90
B=48
We can reason that C will be equal to 90 since it is the right angle. So to find B we have to subtract 90 from 180 to get 90 then subtract 42 to get 48
B=48 degrees
What is the solution to the situation below? The sum of three consecutive integers is 42
Answer:
13,14,15
Step-by-step explanation:
let the first number be n
The next 2 consecutive numbers will be
n+1 and n+2
Sum of these numbers is 42
n+ n+1+n+2=42
Combine like terms
3n+3=42
3n=42-3=39
n=39/3=13
So the numbers are
n=13
n+1=13+1=14
n+2=13+2=15
What does n equal?
4n+2n=18
Solve for 6x+3x-4=32 and find what is 2x
Answer:x=4 2(4)= 8

9x=36
36/9=4
You divide first what operation would you use last 18(d/3-9)=198
Answer:
addition
Step-by-step explanation:
18 ( d - 9 ) = 198
3
divide both side by 18
d - 9 = 198
3 18
d - 9 = 11
3
multiply both sides by 3
d - 27 = 33
add 27 to both sides
d = 33 + 27
lastly, add them together
d = 60
therefore, the last step is addition
If I said that in three days' time it would be a Thursday, I am sure that most of you would have no difficulty telling me that today was a Monday.
Try this one then. Yesterday was two days before Monday. What day is it today? Yes, you're right again. It's Sunday. Do you get the idea?
Now let's tackle a similar question from The National Mathematics Contest (1991) Paper:
Three days ago, yesterday was the day before Sunday. What day will it be tomorrow?

— 7х – 10 = 18 + 3x
Solve the equation
Answer:
-2.8 = x
Step-by-step explanation:
-7х – 10 = 18 + 3x
+7x. +7x
-10. = 18+ 10x
-18. -18
-28. = 10x
/10. /10
-2.8 = x

Does this equation has one solution, no solution, or infinitely many solutions? 2(x + 2) =2x - 8 Question
Answer:
no solution
Step-by-step explanation:
2(x + 2) = 2x -8
2x+4 = 2x-8
2x - 2x =-8 - 4
0 = -12
if the numbers r not the same on both right and left side it have no solution.

M is the midpoint of CD. C has coordinates (-1, -1) and
M has coordinates (3, 5). Find the coordinates of D.
o (-5, -7)
O (4, 6)
O (6, 10)
0 (7, 11)
Answer:
(7, 11)
Step-by-step explanation:
If a line segment has endpoints at A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]), the coordinates of the midpoint O(x, y) of the segment AB is given by the formula:
[tex]x=\frac{x_1+x_2}{2}\\\\y=\frac{y_1+y_2}{2}[/tex]
Given the midpoint M(3, 5) of the segment CD with the coordinates of C at (-1, -1). Let the coordinates of D be at ([tex]x_2,y_2[/tex]). Hence:
[tex]x=\frac{x_1+x_2}{2}\\\\ 3=\frac{-1+x_2}{2} \\\\6=-1+x_2\\\\x_2=6+1\\\\x_2=7\\\\y=\frac{y_1+y_2}{2}\\\\ 5=\frac{-1+y_2}{2} \\\\10=-1+y_2\\\\y_2=10+1\\\\y_2=11[/tex]
Hence the coordinates of D is at (7, 11)
A running shoe manufacturer has a fixed overhead of $ 580000.00, variable costs of $ 50.00, and a selling price of $ 100.00.
(c) Smallest number of pairs of shoes the company must sell to turn a profit:
(d) Total profit
Answer:
To make a profit the company must sell 11601 units.
Step-by-step explanation:
Giving the following information:
Fixed costs=$580,000
Unitary variable costs= $50
Unitary selling price= $100
First, we need to calculate the break-even point in units:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 580,000 / (100 - 50)
Break-even point in units= 11,600 units
To make a profit the company must sell 11601 units.
In order to determine the total profit, you need to use the following formula:
Total profit= 50*x - 580,000
x= units sold
For example:
x= 15,000
Total profit= 50*15,000 - 580,000
Total profit= $170,000
Point O is on line segment NP. Given OP = 10, NP = 2x, and NO = x +7,
determine the numerical length of NO.
Answer: NO =
Answer:
Given : NP is a line segment
and O is the mid point
therefore, we can write
NP = NO + OP
now put the values
under NP write 2x , NO = x+7 , OP = 10
Therefore the equation that comes to us after putting values is
2x = x+7 + 10
now solving
2x - x = 7+10
x = 17
therefore
numerical length of NO = x+7
i.e. , 17 + 7 = 24

A student found the volume of a rectangular pyramid with a base area of 92 square meters and a height of 54 meters to be 4,968 cubic meters. Explain and correct the answer.
1 656 m³
Step-by-step explanation:The volume of a rectangular pyramid formulaV = B×h/3
= 92m²×54m/3
= 92m²×18m
= 1 656 m³Answer:
v = 1656 cubic meters
Step-by-step explanation:
what we have = base area = 92 square meters
= height = 54 meters
the volume formula of a rectangular pyramid = V=lwh /3
since base area = lw
lw = 92 meters
now we can write - 92* 54 /3
= 4968 /3
= 1656
So the corect answer is 1656 cubic meters and the student is wrong.

what is the21st term of -3,2,7
Answer:
102
Step-by-step explanation:
The first step is to find out how to find the next number in the term.
In this we can see that to get to the next number in the term we need to add 5.
The easiest way to figure out the 21st term of this, would be to multiply 5×21. This is equal to 105.
But since we started at three less than 5, we need to subtract 3 from 105. 105-3=102.
The 21st term is 102.
