Answer:
x = 15°
Step-by-step explanation:
Complementary angles are two angles whose sum = 90°
∠A + ∠B = 90°
3x + 45 = 90
3x = 45
x = 45/3
x = 15°

Answer:
p = 35°
Step-by-step explanation:
Angles on a straight line add up to 180° so:
2p + 5 + 3p = 180° (simplify)
5p + 5 = 180° (subtract 5 from both sides)
5p = 175° (divide both sides by 5)
p = 35°
Hope this helps!
Answer:
p=35
Step-by-step explanation:
You have to add the two together and set them equal to 180, so 2p+5+3p=180 so 5p=175, so p=35.

Write the equation of the line perpendicular to y = 5x + 1 that passes through the point ( – 5,1).
Type an equation using slope-intercept form or using the given point in point-slope form.
(Use integers or simplified fractions for any numbers in the equation.)
Answer:
y = -1/5x
Step-by-step explanation:
Using the 'y=mx+c' form for the equation:
Find the slope (m):
Since the product of both slopes should be -1 (if they are perpendicular),
s₁s₂ = -1
5*s₂ = -1
s₂ = -1/5x
Hence, the slope (m) is -1/5x.
Substituting the slope value into 'y=mx+c':
y = -1/5x+c -----(1)
Substituting the point (-5,1) into the equation (1):
1 = -1/5 * (-5) + c
1 = 1 + c
c = 0
Substitiuting 'c=0' into 'y = -1/5x+c':
y = -1/5x
Hence,
y = -1/5x

Answer:
y = 6x-13
Step-by-step explanation:
Given: y+1=6(x-2)
Distribute 6: y +1 = 6x -12
Isolate y: y = 6x -13 (subtracted 1 from both sides)
This is now in the form y = mx +b
Hope this helps!
What is the equation of the line that passes through the point (5, 4) and is perpendicular to the line whose equation is 2x + y = 3 in standard form?
So a line that is perpendicular is a line that intercepts other line at a 90 degree angle.
Slope of perpendicular lines is the opposite sign and the reciprocal of the other.
So if your slope was 2 the perpendicular line would have a slope of -1/2.
So the equation, 2x + y = 3
Can be rewritten as
y= -2x+3
Perpendicular slope: 1/2
Since it intercepts/ passes the coordinates (5,4) it means that those values are included in the function input x and output y.
y=mx+b
4=1/2(5)+b
Solve for b (y intercept)
4-2.5=b
1.5=b
So the equation of the perpendicular is
y=1/2x+3/2 or y=.5x+1.5
Blue Tide Swim Shop is having its annual summer sale, when every item in the store gets
marked down, During the sale, rashguards sell for $5 less than full price. Miguel purchases 3
rashguards and pays a total of $60.
Which equation can you use to find how much money, f, each rashguard costs at full price?
The full price of a rashguard is $25 and the expression for the full price is 3 (x - 5) = 60.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the full price of each rashguard be x,
Rashguards sell for $5 less than full price.
x - 5
Miguel purchases 3 rashguards and pays a total of $60.
3 (x - 5) = 60
Simplifying,
x - 5 = 60 / 3
x - 5 = 20
x = 20 + 5
x = 25
Thus, the full price of a rashguard is $25 and the expression for the full price is 3 (x - 5) = 60.

A school gym is set up for an
assembly. There are 17 rows with 28
chairs in each row. Parents are sitting
in half the chairs, but the other half
are empty. How many chairs are empty?
Answer:
238 chairs are empty
Step-by-step explanation:
Firstly,
you'll have to times 17 by 28 to get the total chairs in the school gym
17 × 28
= 476
Next,
divide it by 2 because half of the gym???
476/2
= 238
So, the amount of the empty chairs in the school gym are 238 in total ｡◕‿◕｡

Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (- 1, 2) ← 2 points on the line
m = [tex]\frac{2-1}{-1-(-2)}[/tex] = [tex]\frac{1}{-1+2}[/tex] = [tex]\frac{1}{1}[/tex] = 1
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = x + 2 ← equation of line
A skyscraper is a rectangular prism with a height of 398 meters. The bases are squares with sides that are 62 meters. What is the surface area of the skyscraper?
Answer:
106,392 meters squared.
Step-by-step explanation:
Surface area of a rectangular prism or cuboid is given by:
SA = 2 (lw + wh + lh)
where:
· l is the length of the cuboid.
· w is the width of the cuboid.
· h is the length of the cuboid.
Here we have h = 398 m, l = w = 62 m because this is a square base.
So we get:
SA = 2 ( 398 · 62 + 62² + 398 · 62)
= 2 (24676 + 3844 + 24676)
= 2 · 53196
= 106392 m²
Choose the option that best describes what it means to get 70% on a test.
If there were 70 points possible, you earned all of them.
If there were 100 points possible, you earned 7.
If there were 100 points possible, you earned 30.
O If there were 100 points possible, you earned 70.
Answer:
If there were 100 points possible, you earned 70.
Step-by-step explanation:
So 70% means 70 per cent which means 70 parts per 100 parts. So this means that out of the total 100 maximum possible points, you have earned 70 of them but did not earn 30

In the figure below, if m<1 = (x + 16)° and m
The < sign is angle
Answer:
Step-by-step explanation:
∠1 + ∠BFE = 180 {linear pair}
x + 16 + 3x + 20 = 180
x + 3x + 16 + 20 = 180 {Combine like terms}
4x + 36 = 180
Subtract 36 from both sides
4x = 180 - 36
4x = 144
Divide both sides by 4
x = 144/4
x = 36
If the room is a 14 by 12' rectangle then the strip of wallpaper needs to be at least how long?
Answer:
52 ft.
Step-by-step explanation:
In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.
So, rectangles has opposite sides equal, therefore, the perimeter should be:
; having L as the larger side.
Hence, the strip of wallpaper needs to be as least 52 ft.

equation of line M is Y=5/8x+1 . Line N is perpendicular to M. What is the slope of line N?
Step-by-step explanation:
the slope of a line is always the factor of x in the equation. in our case here : 5/8.
the slope is the y/x ratio indicating how many units y changes, when x changes by a certain amount of units (e.g. when going from one point on the line to another).
the perpendicular slope (crosses the original line in a right angle = 90 degrees) turns x and y upside-down and flips the sign.
so, in our case, it is -8/5.
4(3 × 2) + (8 - 3)^2 - 6^2 + 3 × 9 - 2^3 + 1
