Math is used to help calculate certain things such as taxes and such, but they are mostly important for jobs since certain jobs require knowledge of math. Jobs such as working in a branch of engineer, architecture, etc.
An angle measures 107.8° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
x=36.1
supplementary angle = 143.9 degrees
Step-by-step explanation:
angle: x
supplementary angle: 180-x
x = (180-x)-107.8
2x = 72.2
x = 36.1 degrees
180-x = 143.9 degrees
supplementary angle = 143.9 degrees
x measures 107.8 less than 180-x
x=180-x-107.8
x=72.2-x
Add x to both sides
2x=72.2
Divide both sides by 2
x=36.1

Find: (4x²y3 + 2xy2 - 2y) - (-7x?y3 + 6xy2 – 2y)
Place the correct coefficients in the difference.
Answer:
The coefficients are
11,-4 and 0.
Step-by-step explanation:
We are given two algebraic expressions. We are subtracting the second from the first.
First one is:
(4x²y3 + 2xy2 - 2y)
Second expression is:
(-7x?y3 + 6xy2 – 2y)
The given expression:
(4x²y3 + 2xy2 - 2y) - (-7x?y3 + 6xy2 – 2y)
The coefficients are
11,-4 and 0.
Which of the following options represents the graph of the function show above? f(x) = (x+3) ^3- 1
f(x) = (x-3) ^311
f(x) = (x-3)^3+ 1
f(x) = ( x + 3)^3+1
Answer:
C
Step-by-step explanation:
First, notice that this is a cubic function.
The standard form for a cubic function is:
[tex]f(x)=a(x-b)^3+c[/tex]
Where a is the vertical stretch, b is the horizontal shift, and c is the vertical shift.
From our graph, we can see that unlike the parent function, x³, this cubic is 3 units to the right and 1 unit up from the standard position.
Therefore, our b is +3 and c is +1. Let's substitute these values. Also, let's assume a is 1. So:
[tex]f(x)=(x-3)^3+1[/tex]
Therefore, our answer is C.
And we're done!

For a science experiment, Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different experiment, Bobby dissolved 2.0 pounds of salt in 7.0 pints of water. Which person made a more concentrated salt solution? Explain. Use 1 L = 2.11 pints. Round your answer to the nearest hundredth.
Step-by-step explanation:
The concentration of Marcia's solution is:
1.0 kg / 3.0 L = 0.33 kg/L
The concentration of Bobby's solution is:
(2.0 lb × 1 kg / 2.2 lb) / (7.0 pints × 1 L / 2.11 pints) = 0.27 kg/L
Therefore, Marcia's solution is more concentrated.
How many solutions does 6d+8=14+3d have?
Answer:
d =2
Step-by-step explanation:
6d+8=14+3d
Subtract 3d from each side
6d-3d+8=14+3d-3d
3d +8 = 14
Subtract 8 from each side
3d +8-8 = 14-8
3d =6

Morris borrowed $6 from his mother. so far, he has repaid $4. if debt is represented as a negative number, what number sentence shows the amount of jack's remaining dept.?
if it was negitive I would be -2
Step-by-step explanation:
so 6-4=2 and if you make that negative it would be -2
Answer:
-$6 + $4 = -$2
Step-by-step explanation:
Since Morris borrowed 6 dollars to begin with, the first term in my equation is -6$, representing the debt he has incurred from taking a loan of 6 dollars from his mother. After paying $4 dollars, he would still be in debt of $2 to his mother. Since he is still in debt of 2 dollars, the furthest right term in my aforementioned equation is -$2.

What is 3000 times 1000?
Answer:
3000000
Step-by-step explanation:
:D
The equivalent value of the equation is A = 3000000
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be p = 3000
Let the second number be q = 1000
Now , A = pq
where A = 3000 x 1000
On simplifying the equation , we get
A = 3000 x 1000
So , the left hand side of the equation is equated to the right hand side by the value of ( 3000 x 1000 )
A = 3000000
Therefore , the value of A = 3000000
Hence , the expression is A = 3000000

which diagram show lines that must be parallel lines cut by a transversal
Answer: hope i helped with this answer~
Step-by-step explanation:
The fourth diagram show lines that must be parallel lines cut by a transversal
What is Straight line?A line is an infinitely long object with no width, depth, or curvature.
Parallel lines refers to two lines which can be found on the same plane, at an equidistance and does not meet.
A transversal is defined as a line that passes through two lines in the same plane at two distinct points in the geometry.
The fourth diagram has two same-side interior angles that are supplementary (add to 180°).
The converse of the same-side interior angle theorem states that if two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.
Hence, the fourth diagram show lines that must be parallel lines cut by a transversal
