Answer:
141°
Step-by-step explanation:
The sum of the internal angles can be calculated using the following formula:
(number of sides - 2) x 180°
This polygon has 7 sides, so (7 - 2) x 180° = 900° total internal angle.
Subtract the other given angles from 900°.
(900 - 131 - 122 - 125 - 148 - 107 - 126)° = 141°
Answer:
x equals 141°
Step-by-step explanation:
The sum of interior angles of this figure is 900°. This was found using the formula (n-2) x 180 where 'n' means number of sides. This figure has 7 sides. So the sum of interior angles would be:-
(7 - 2) x 180°
5 x 180°
= 900°
All the given angles + x gives 900°.
So, to find 'x' we can do the following:-
148° + 125° + 122° + 131° + x° + 126° + 107° = 900°
759 + x = 900
x = 900 - 759
x = 141°

Add and subtract the second term to the expression and factor by grouping.
( z + 6 ) ( 2 z 2 − 5 )
Answer:
2z^2; –5
Step-by-step explanation:
2z3 = 2 • z • z • z 12z2
= 2 • 2 • 3 • z • z
The GCF is 2z2.
–5z3 = –1 • 5 • z • z • z
–30 = –1 • 5 • 6
The GCF is –5.

Find the surface area.

Do NOT round your answer.
Answers
Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=5,h=30,\pi=3.14[/tex] in the above formula, we get
[tex]SA=2(3.14)(5)^2+2(3.14)(5)(30)[/tex]
[tex]SA=2(3.14)(25)+942[/tex]
[tex]SA=157+942[/tex]
[tex]SA=1099 [/tex]
Therefore, the surface area of the cylinder is 1099 square inches.
A rectangular block of wood measures 5 inches wide. Over time, the width of the block of wood will shrink by 5%. A builder lets the block of
wood shrink. He wants to use it to fill a gap that measures 3.5 inches wide.
How much does the builder need to cut off the wood block so that it will fit exactly in the gap? Enter the answer in the box.
The builder needs to cut
inches off the block of wood.
Answers
Answer: [tex]3.675\ in.[/tex]
Step-by-step explanation:
Given
Wood shrinks 5% over the period of time
The width of the gap is 3.5 inch
The length of the rectangular block is 5 inch
So, the builder cut the rectangular block 5% bigger to compensate for the shrinkage
Required length is
[tex]\Rightarrow 3.5+5\%\times 3.5\\\Rightarrow 3.5+0.05\times 3.5\\\Rightarrow 3.5[1+0.05]\\\Rightarrow 3.675\ in.[/tex]

As part of a survey, 150 students were asked if they eat breakfast on school days. Of these students, 45 stated they eat breakfast on school days What percentage of the students in the survey stated they eat breakfast on school days?
Answers
Answer:
