Answer:
m∠B = 3°
Step-by-step explanation:
Complementary angles when combined will equal 90° in total.
∠A + ∠B = 90
m∠A = 87° {Given}
Plug in 87 for ∠A in the given equation, and solve for ∠B
87 + ∠B = 90
Isolate the variable. Subtract 87 from both sides of the equation:
87 (-87) + ∠B = 90 (-87)
∠B = 90 - 87
∠B = 3°
m∠B = 3° is your answer.

What is the value of X? ( if you are confused please look at the picture provived below)
Answer:
X = 14 I used a calculator an showed work
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
It is given that ∠AOB is a straight line. The definition of a line states that it is 180°, so any line equals to a measure of 180°.
Step 1: Set up equation
m∠AOC + m∠COD + m∠DOB = 180°
(5x) + (3x + 30) + (2x + 10) = 180°
Step 2: Solve for x
Combine like terms: 10x + 40 = 180 Subtract 40 on both sides: 10x = 140Divide 10 on both sides: x = 14Step 3: Check
Plug in x to verify it's a solution.
Substitute: 10(14) + 40 = 180Evaluate: 140 + 40 = 180Evaluate: 180 = 180Tim has a board that is 5/6 feet long. He painted 2/18 feet of his

1. Henry is using a total of 40 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each 8 ft. high. The top, bottom, and two shelves are all the same length, labeled .
Part A: Construct an equation to model the situation. (5 points)
Part B: Solve the equation. Show all your steps.
(5 points)
Part C: Use the solution to answer the question in a complete sentence. (5 points)
Answer:
Part A:
40 = 16 + 4·s
Part B:
The length of the top and bottom and the two shelves are each = 6 ft.
Part C:
The width of the bookshelf is 6 feet
Step-by-step explanation:
The given parameters are;
The length of the lumber Henry is using to make the book case = 40 ft.
The height of the left and right side of the book case = 8 ft. each
The length of the top and bottom and the two shelves are each = s
Therefore, we have;
Part A:
The equation is given as follows;
40 = 8 × 2 + 4·s = 16 + 4·s
40 = 16 + 4·s
Part B:
The solution of the equation is given as follows;
40 = 16 + 4·s
4·s= 40 - 16 = 24
s = 24/4 = 6 ft.
s = 6 ft.
The length of the top and bottom and the two shelves are each = 6 ft.
Part C:
The width of the bookshelf is 6 feet
Help Needed!! Find The Measure Of Angle A In The Triangle
Answer:
A=40°
Step-by-step explanation:
All angles in a triangle add up to 180°, so we take 60 away from 180 because we know that angle.
180-60=120
Next, we add up the number of x,
10x+20x=30x
Third, we need to find out what x is, so we divide 120 by 30, which gives us 4.
x=4
to find out what 10x is (A), we multiply 4 by 10
4×10=40
A=40
passes through (8,-6) perpendicular to 2x+y=-4
Answer: y = 0.5x - 10
Step-by-step explanation:
2x + y = -4
y = -2x - 4
perpendicular, so slope = 1/2
y + 6 = (1/2)(x - 8)
y = (1/2)x - 10

i think u have to divide 7260 by 90
80 premium memberships must the center sell in order to earn $7260 in membership sales.
What is division?Division is the process of splitting a number or an amount into equal parts.
here, we have,
The premium membership is $90,
and the regular membership is $60.
now,
No. of premium memberships must the center sell in order to earn $7260 in membership sales = $7260÷$90
=7260/90
≈80
hence, 80 premium memberships must the center sell in order to earn $7260 in membership sales.

gb + Nb = 2F2
solve for b
The required solution for b from the given equation is b = 2F²/(g + N).
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
gb + Nb = 2F²
For the value of b let us isolate b in one side and other terms into other.
⇒ (g + N)b = 2F²
Dividing both the side by (g + N),
⇒ (g + N)b/(g + N) = 2F²/(g + N)
Solving we get,
b = 2F²/(g + N)
Thus, the required solution for b from the given equation is b = 2F²/(g + N).

Given:
Original price = $231.00
Markup price is [tex]\dfrac{1}{6}[/tex] of the original price.
To find:
The markup price for the concert ticket.
Solution:
It is given that, markup price is [tex]\dfrac{1}{6}[/tex] of the original price. So,
[tex]\text{Markup price}=\dfrac{1}{6}\times \text{Original price}[/tex]
[tex]\text{Markup price}=\dfrac{1}{6}\times 231[/tex]

for each of the values, substitute x for that value.
f(0) = 2*0
f(0) = 0
f(1) = 2 * 1
f(1) = 2
