The measures of the angles of a triangle are 50 degrees, 35 degrees, and 95 degrees. What is the measure of the largest exterior angle of the triangle?
A) 85 degrees
B) 130 degrees
C) 145 degrees
D) 150 degrees
Answer:
145 degrees (c)
Step-by-step explanation:
Take your smallest interior angle (35 degrees) & subtract it from 180.
That will give you your largest exterior angle.
180 - 35 = 145 degrees

What is the surface area of the rectangular prism shown by the net?
Answer:
736 cm^2.
Step-by-step explanation:
Adding the individual rectangles:
Surface area = 8*10 + 8*10 + 8*16 + 8*16 + 10*16 + 10*16
= 160 + 256 + 320
= 736.

Answer:
x=2
Step-by-step explanation:
5x-1=3x+3
2x-1=3
2x=4
x=2
Answer:
x = 2
Step-by-step explanation:
We can say that both the triangles are congruent by the "if two angles of given triangles are congruent then the triangles are congruent" theorem, so we can set both equations equal to each other:
5x - 1 = 3(x + 1)
=> 5x - 1 = 3x + 3
=> 2x - 1 = 3
=> 2x = 4
=> x = 4/2
=> x = 2
Hope this helps!

Answer:
x is equal to 61

What is the minimum value?
Guys pls help me!!!!!
Answer:
2) y = 0.5^x
Step-by-step explanation:
Plug in x coordinates to see which equation makes up the graph. We can see that the y values lower even after using positive numbers so this eliminates the possibility of 1) as that would make the y values increase. Starting with coordinates (-1, 2), let's plug these into 2):
y = 0.5^x
2 = 0.5^-1
2 = 2
Correct
Use another pair of coordinates to see if it still works:
(-2, 4)
4 = 0.5^-2
4 = 4
It does!
Check the other equations just to make sure this is the only option:
2 = 5^(- - 1)
Negative + Negative = Positive
2 = 5^1
2 = 5
Incorrect.
2 = 0.5^(- - 1)
2 = 0.5^1
2 = 0.5
Incorrect.
This means our first solution is the only solution.
Solve for y -72=8(y-3)
Answer:
Step-by-step explanation:
y - 72 = 8(y - 3)
Distribute the 8 into (y - 3).
y - 72 = 8y - 24
Subtract 8y from both sides.
-7y - 72 = -24
Add 72 to both sides.
-7y = 48
Divide both sides by -7.
y = -48/7 or approxametly -6.9.
Proof:
y - 72 = 8(y - 3)
Substitute variable.
-48/7 - 72 = 8(-48/7 - 3)
Subtract.
-552/7 = 8(-69/7)
Multiply 8 by the inside term -69/7.
-552/7 = -552/7.

Georgina likes to read during her summer break. The table below shows the number of pages in each book she read last summer and the number of pages in each book she read this summer.

220
190
180
190
This Summer
150
170
150
190
180
What inference can someone draw about the data?
The books she read this summer had more pages, on average, than last summer.
The number of pages in each book varied more last summer than this summer.
Last summer, the average book had nearly twice the number of pages than the average book has this summer.
This summer, the number of pages in a book varied nearly twice as much as the number of pages in last summer's books
The correct answer would be:
B. The number of pages in each book varied more last summer than this summer.
Step-by-step explanation:
I was doing my test and this was the correct answer. Sorry if this is too late for you.! I hope you have a great day.
The inference that can be drawn from the data is the number of pages in each book varied more last summer than this summer.
How to measure variance in data?Range can be used to measure variance in a data set. Range is the difference between the largest number and the smallest number. The larger the difference, the greater the variance.
Range= largest number - smallest number
Range of pages read this summer = 180 - 150 = 30
Range of pages read last summer =220 - 140 = 80

Answer:
[tex]\text{a. }x=7, x=-7, \\\text{b. }x=16, x=-16, \\\text{c. }x=3, x=-17, \\\text{d. }x=7, x=-7[/tex]
Step-by-step explanation:
For [tex]|x|=y[/tex], we have two cases:
[tex]\begin{cases}x=y, \\x=-y\end{cases}[/tex]
Using this, we can solve all four of the problems:
[tex]\text{a. }|x|=7,\\\begin{cases}x=7, \\x=-7\end{cases}[/tex]
[tex]\text{b. }|2x|=32,\\\begin{cases}x=16, \\x=-16\end{cases}[/tex]
[tex]\text{c. }|x+7|=10,\\\begin{cases}x+7=10, x=\boxed{3,} \\x+7=-10, x=\boxed{-17}\end{cases}[/tex]
[tex]\text{d. }5|x|=35,\\\begin{cases}x=7, \\x=-7\end{cases}[/tex]
Answer:
a) x = 7, x = - 7
b) x = 16, x = - 16
c) x = 3, x = - 17
d) x = 7, x = - 7
Step-by-step explanation:
When you have absolute value on a variable, the variable has two results.
Example:
lxl = 2
x = 2, or x = - 2
a. lxl = 7
x = 7, x = - 7
b. l2xl = 32
l2xl ÷ 2 = 32 ÷ 2
lxl = 16
x = 16, x = - 16
c. lx + 7l = 10
x + 7 = 10
x + 7 = - 10
x + 7 = 10
x + 7 - 7 = 10 - 7
x = 3
x + 7 = - 10
x + 7 - 7 = - 10 - 7
x = - 17
d. 5lxl = 35
5x = 35
5x = - 35
5x = 35
5x ÷ 5 = 35 ÷ 5
x = 7
5x = - 35
5x ÷ 5 = - 35 ÷ 5
x = - 7

Answer:
The bject will move forward
Step-by-step explanation:
When more than one force acts upon an object, the vector sum of these forces is the resultant force. When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. ... That is, there is zero acceleration.
