Answer:
70
Step-by-step explanation:
the red lines mean the two sides are equal
so its an isosceles triangle meaning the two angles other than the 40° one are equal
the inner angles of a triangle must add up to 180
so 180-40 = 2x
140 = 2x
x = 140/2 = 70
Answer:
x=70
Step-by-step explanation:
let unknown angle be a
then,a=x(base angle of an isosceles triangle)
a+x+40=180
x+x=180-40(a=x)
2x=140
x=70

(05.01)A picture is 5 inches wide and 8 inches tall: A rectangle is shown. The length of the rectangle is labeled 5 inches. The width of the rectangle is labeled 8 inches. A photographer wants to use a scale factor of 2.5 to enlarge a picture. What will the area of the picture be after it is enlarged? 40 in2 250 in2 100 in2 81.9 in2
Answer:
B. 250 in²Step-by-step explanation:
Dimensions of the picture:
5 in and 8 inArea of the picture:
5*8 = 40 in²Scale factor = 2.5
Enlarged picture's area:
40*2.5*2.5 = 250 in² (scale factor affects both dimensions)Option B is correct
The area of the picture after it is enlarged is 250 inches².
Given that,
The length of the rectangle is labeled 5 inches. The width of the rectangle is labeled 8 inches.
A photographer wants to use a scale factor of 2.5 to enlarge a picture.
Based on the above information, the calculation is as follows:
Here, the dimensions of the picture are 5 in and 8 in
Hence, the area of the picture is,
5 × 8 = 40 in²
Since, Scale factor = 2.5
So, the enlarged picture's area would be,
40 × 2.5 ×2.5
= 250 in²

a carnival game has 18 balloons. Amy popped 2/3 the first game and 5/6 the second game. How many more balloons did she pop the second game?
Answer:
3 more balloons she has popped in the second game.
Step-by-step explanation:
Given that,
Total no. of balloons = 18
Amy popped 2/3 the first game and 5/6 the second game.
Balloons popped in first game = [tex]\dfrac{2}{3}\times 18=12\ \text{balloons}[/tex]
Balloons popped in second game = [tex]\dfrac{5}{6}\times 18=15\ \text{balloons}[/tex]
Difference of balloons popped in first and second game,
= 15-12
= 3 balloons
Hence, 3 more balloons she has popped in the second game.

Each statement describes a transformation of the graph of y= x.
Which statement correctly describes the graph of
y= x - 8?
A. It is the graph of y= x translated 8 units to the left
B. It is the graph of y= x translated 8 units up.
C. It is the graph of y=x translated 8 units down.
D. It is the graph of y=xwhere the slope is decreased by 8.
Answer:
c
Step-by-step explanation:
its in slope intercept form, or y=mx+b where b is the y intercept, i.e. how far down the line hits the y axis. m would be the slope but we dont need to worry about that for now. since b is the y intercept, -8 would mean 8 units down

What is the y-intercept of this function?

Answer:
4.00
Step-by-step explanation:
Given
x: 2 , 5 , 8 , 12
y: 8.50, 15.25, 22.00. 31.00
Required
Determine the y intercept
First, we calculate the slope:
[tex]m = \frac{y_2- y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (2,8,50)[/tex]
[tex](x_2,y_2) = (12,31.00)[/tex]
[tex]m = \frac{31.00 - 8.50}{12 - 2}[/tex]
[tex]m = \frac{22.5}{10}[/tex]
[tex]m = 2.25[/tex]
Next, we calculate the equation:
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (2,8,50)[/tex]
[tex]m = 2.25[/tex]
The equation becomes:
[tex]y - 8.50 = 2.25(x - 2)[/tex]
[tex]y - 8.50 = 2.25x -4.5[/tex]
Make y the subject
[tex]y = 2.25x -4.5+8.50[/tex]
[tex]y = 2.25x +4[/tex]
Take [tex]x =0[/tex]; to get the y intercept
[tex]y = 2.25*0 +4[/tex]
[tex]y = 4[/tex]
Hence, the y intercept is 4.00

Write the equation of a line that is parallel to the graph of 3y = 2x − 3 and passes through the point
(−3, 4).
Answer:
y = 2/3x + 6
Step-by-step explanation:
First, put the original equation in y = mx + b form
3y = 2x − 3
y = 2/3x - 1
The slope of the other line will also be 2/3, since parallel lines have the same slope.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
4 = 2/3(-3) + b
4 = -2 + b
6 = b
Plug in the slope and b:
y = 2/3x + 6 is the equation of the line

There are 21 jars of peanut butter for sandwiches. Each sandwich uses 1/5 of a peanut butter jar. How many sandwiches can be made from all the peanut butter?
Answer: 105 sandwiches can be made from all the peanut butter.
Step-by-step explanation:
Given: Total jars of peanut butter = 21
Part of peanut butter required for each sandwich = [tex]\dfrac15[/tex]
Total number of sandwiches made = ( Total jars of peanut butter ) ÷ (Part of peanut butter required for each sandwich)
[tex]=21\div\dfrac15\\\\=21\times5\\\\=105[/tex]
Hence, 105 sandwiches can be made from all the peanut butter.

Step-by-step explanation:
A right angle is an angle whose measure is equal to [tex]90^{o}[/tex]. As the measure of two right angles equals angle on a straight line, while four right angles equal the sum of angles at a point.
Given: <ABC, <DEF are right angles.
The missing reasons in the steps of the proof are:
A: m<ABC = [tex]90^{o}[/tex] and m<DEF = [tex]90^{o}[/tex] (Meaning of a right angle)
