Answer:
x=4 degrees
Step-by-step explanation:
its an equilateral triangle so all sides are equal, if one angle is 10x+20,then the rest are each 10x+20.This is a triangle and it adds up to 180 degrees. So in total, (10x+20)×3=30x+60.So you do this, 30x +60=180 degrees, you take the sixty to the other side and subtract it from 180 ,you'll get 120 degrees, then divide 120by 30x

In a scale drawing of a house, 2 inches : 5 feet. The actual kitchen of the house will be 17 feet long. How long will the drawing of the kitchen be? ( Hint: Not A)
A. 5.2
B. 6.8
C. 7.5
D. 8
Answers
9514 1404 393
Answer:
B. 6.8
Step-by-step explanation:
The drawing measure can be found using the proportion ...
drawing/actual = 2 in/(5 ft) = x/(17 ft)
Multiplying by 17 ft gives ...
x = (2 in)(17/5) = 6.8 in
The drawing of the kitchen will be 6.8 inches.
Pllllzzzzz hellllpppp!!! What is an equation of the line that passes through the point (2,2) and is parallel to the line x-2y=4
Answers
Answer:
-2y = 4 - x
2y = x - 4
y = 1/2x - 2
1/2 is the slope of both lines.
y = mx + b
Substitute the given point and the common slope
2 = 1/2 x 2 + b
2 = 1 + b
b = 1
y = 1/2x + 1
The equation of the line that passes through the point
(2, 2) and is parallel to the line x - 2y = 4 is y = 1/2x + 1 or 2y = x + 2.
hope this helps u
plz give me the brainliest i really need it
Answer:
x - 2y = - 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 )
Given
x - 2y = 4 ( subtract x from both sides )
- 2y = - x + 4 ( divide all terms by - 2 )
y = [tex]\frac{1}{2}[/tex] x - 2 ← in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
Parallel lines have equal slopes, thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 2) into the partial equation
2 = 1 + c ⇒ c = 2 - 1 = 1
y = [tex]\frac{1}{2}[/tex] x + 1 ← equation in slope- intercept form
Multiply through by 2
2y = x + 2 ( subtract 2y from both sides )
0 = x - 2y + 2 ( subtract 2 from both sides )
- 2 = x - 2y, that is
x - 2y = - 2 ← equation in standard form

The average rate of change of the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex] is -1
Step-by-step explanation:
We are given the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex]
We need to find average rate of change.
The formula used to find average rate of change is : [tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}[/tex]
We have b=-1 and a=-11
Finding g(b) = g(-1)
[tex]g(x)=x^2+10x+18\\Putting \ x=-1\\g(-1)=(-1)^2+10(-1)+18\\g(-1)=1-10+18\\g(-1)=9[/tex]
Finding g(a) = g(-11)
[tex]g(x)=x^2+10x+18\\Putting \ x=-11\\g(-11)=(-11)^2+10(-11)+18\\g(-1)=121-110+18\\g(-1)=29[/tex]
Finding average rate of change
[tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}\\Average \ rate \ of \ change=\frac{9-29}{-1-(-11)}\\Average \ rate \ of \ change=\frac{-10}{-1+11}\\Average \ rate \ of \ change=\frac{-10}{10}\\Average \ rate \ of \ change=-1[/tex]
So, the average rate of change of the function [tex]g(x)=x^2+10x+18[/tex] over the interval [tex]-11 \leq x\leq -1[/tex] is -1

O The quadrilaterals have corresponding angles that are congruent.
0 The quadrilaterals are all the same size and shape.
O The quadrilaterals are different shapes but the same size.
O The quadrilaterals have corresponding sides that are congruent.
Answers
Answer:
B. The quadrilaterals are all the same size and shape.
Step-by-step explanation:
Lauren was drawing a tower ONLY using SIMILAR quadrilaterals, so since that is, since the quadrilaterals are similar, then they must have the same size and shape.
The statement i.e. true for quadrilaterals should be
B. The quadrilaterals are all the same size and shape.
What are quadrilaterals?A quadrilateral refer to the closed shape also it is the type of polygon that comprises of four sides, four vertices, and the four angles. Here the sum of the interior angle should be equivalent to the 360 degrees.

The quick way we can see this without having to graph or do any algebra is to look at the two slopes of the lines.
y = x+1 has slope of 1
y = -x+5 has slope of -1
Recall that y = mx+b has slope m.
The two different slopes (1 and -1) indicate the lines are not parallel, so they must intersect exactly once. This intersection is the where the solution is located.
Sales tax on a shirt is 0.07 times the cost of the shirt. The sales tax for a shirt is $1.26. Which equation could you use to find the cost, c, of the shirt before sales tax? A. 0.07 · c = 1.26 B. 0.07 · 1.26 = c C. 0.07 ÷ 1.26 = c D. 0.07 ÷ c = 1.26
Answers
Answer:
Option A: 0.07c = 1.26 is the correct answer
Step-by-step explanation:
Given that the price of shirt is denoted by c.
Given that the sales tax is 0.07 times of the cost of shirt.
Mathematically it can be written as:
[tex]Sales\ tax=0.07c[/tex]
Now it is also given in the statement that the sales tax is $1.26
Putting this value in the above equation
[tex]1.26 = 0.07c[/tex]
As we have to find the cost, dividing both sides by 0.07
[tex]\frac{1.26}{0.07} = \frac{0.07x}{0.07}\\c = \frac{1.26}{0.07}[/tex]
Hence, we saw that the intermediate equation was: 1.26 = 0.07c
So,
Option A: 0.07c = 1.26 is the correct answer
Answer: A. 0.07 · c = 1.26
Step-by-step explanation:
Sales tax (0.07) x cost (c) = price (1.26)

122 - 90 = 32 degrees
32 + 4 = 36 degrees
Answer:
s = 36
Step-by-step explanation:
These lines is 180° in total and the one that is a right triangle has 90° and there is 58° on one so, 180 - 90 - 58 = 32.
32° = s - 4°

How to draw regions covered by inequalities?Suppose there is inequality given as: y ≥ f(x)
The region it covers is the region of value pairs (x,y) for which this inequality holds true.
We've to draw the region covered by it.
For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).
A manufacturing machine has two processes. One of them is repeated 4 times and the second only once. The entire cycle can take no longer than 3 minutes.
Let t be the time of the first process in minutes
s be the time of the second process in minutes
we know that the time of the first process multiplied by 4 (because is repeated 4 times) plus the time of the second process multiplied by 1 (because is repeated only once) must be less than or equal to 3 minutes
So, The inequality that represents this situation is
[tex]4t + s\leq 3[/tex]
The y-intercept of the solid line is the point (0,3)
The x-intercept of the solid line is the point (0.75,0)
