Step-by-step explanation:
Every exterior is 360
So 36 for each exterior.
Decagon interior is 1440
So each interior angle is 144
Answer:
interior angle = 144°
Step-by-step explanation:
A decagon has 10 sides
The sum of the exterior angles of a polygon is 360° , then
exterior angle = 360° ÷ 10 = 36°
The sum of an exterior angle and an interior angle = 180° , then
interior angle = 180° - 36° = 144°

-3(x² +2x-3)+3(x²+4x)
6x + 9
I hope this helps!
Answer:
= 6x +9
Step-by-step explanation:
1. you need to multiply -3 by x² + 2x - 3
so you got -3x² -6x + 9
2. Then, you need to multiply 3 by (x²+4x)
= 3x² + 12x
3. -3x² - 6x + 9 + 3x² + 12x
4. then you need to solve with the same
= - 3x² + 3x²
= 0
= - 6x + 12x
= 6x
5. lastly you will got the answer.
# = 6x +9

'Jill burns 200 calories in a 3/4 hour workout. How many calories will she burn in a 3 hour workout?'
Answer: 800 calories
Step-by-step explanation:
Let us set this up as a fraction
Firstly, convert 3/4 into a decimal
[tex]3 \div 4 = 0.75[/tex]
Now we can set up the fraction
Make sure to put the calories on the same side and hours on the same side as well. So it should be: [tex]\frac{200}{0.75}=\frac{x}{3}[/tex]
Then, solve
[tex]\frac{200}{0.75}=\frac{x}{3}[/tex]
The fractions are supposed to be proportional meaning, if the denominator is a certain number when solved, the numerator should be the same, if solve likely. let me show you:
Divide 3 by 0.75
[tex]0.75 \div 3 = 4[/tex]
Now since the number isn't found yet, we will use the opposite operation, which is multiplication, in this case.
Multiply 200 to 4
[tex]200 \times 4 = 800[/tex]
Therefore, she will burn 800 calories in a 3-hour workout.
Points X, Y, and Z are collinear, with Y in between X and Z. If XY = 5x, YZ = 2x + 7, and XZ = 56, find x.x = 7
When two or more points are on a straight path, then they are collinear. So that in the given question, the value of x is 7.
Two or more points are said to be collinear if and only if they fall on a straight line. Thus, the points can be joined by a single straight line.
From the given question, it can be observed that;
XZ = XY + YZ
But given the following:
XY = 5x, YZ = 2x + 7, and XZ = 56
Then,
56 = 5x + (2x + 7)
= 5x + 2x + 7
56 = 7x + 7
collect like terms to have
56 - 7 = 7x
49 = 7x
x = [tex]\frac{49}{7}[/tex]
= 7
x = 7
Therefore, the value of x is 7.

a tennis shop sold twenty $100 racquets at an 8% profit and ten $80 bags at a 15% loss. The profit on the combined transaction was
PLEASE HELP. I'LL GIVE THE BRAINLIEST.
Answer:
$ 40
Step-by-step explanation:
Rackets:
Cost Price (CP) = $ 100
Profit percent = 8%
Profit = 8% * 100 = [tex]\frac{8}{100}*100 = 8[/tex]
Profit for one racket =$8
Profit for 20 rackets = 8*20 = $ 160
Bags:
CP = $ 80
Loss percent = 15%
[tex]Loss = \frac{15}{100}*80=12[/tex]
Loss for 10 bags = 12 * 10 = $ 120
The profit in the combined transaction = 160 - 120 = $ 40

Find x=
Answer:
N____M____O
NO= NM + MO
(5x+2)=25 + (3x-5)
5x+2=3x +20
5x– 3x = 20 – 2
2x= 18
x=18/2
x=9
If you want (NO , MO )this is the solution
NO= 5x+2=5(9)+2=45+2=47
MO= 3x-5=3(9)-5=27-5=22

The perimeter of a rectangular tray is 28 inches. The length of the tray is 2 inches longer the width of the tray. Determine the dimensions of the rectangular tray.
Step-by-step explanation:
perimeter=28
length=2x
width=x
28=2(x+2x)
28=2x+4x
28=6x
28/6=6x/6
4.67=x
width=4.67
length=2×4.67
=9.34
Using the concept of perimeter of a rectangle, we have that:
The length is of 8 inches.The width is of 6 inches.------------------------------
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
[tex]P = 2(l + w)[/tex]
------------------------------
The perimeter is of 28 inches, thus:
[tex]P = 28[/tex]
[tex]2(l + w) = 28[/tex]
Dividing both sides by 2:
[tex]l + w = 14[/tex]
------------------------------
The length is 2 inches longer than the width, thus:
[tex]l = 2 + w[/tex]
Replacing into the equation, we find the width:
[tex]2 + w + w = 14[/tex]
[tex]2w = 12[/tex]
[tex]w = \frac{12}{2}[/tex]
[tex]w = 6[/tex]
The width is of 6 inches.
------------------------------
The length is:
[tex]l = 2 + w = 2 + 6 = 8[/tex]
The length is of 8 inches.

Given m||n, find the value of x.
t
(7X+7)
(2x+2)
The value of x is 21.
From the attached diagram we can observe that the lines m and n are parallel to each other and these parallel lines are intersected by transversal t.
Let us assume that angle 'y' be a linear angle with (2x + 2)
(Both angles are below line n)
⇒ y + (2x + 2) = 180° .............(1)
So that, angles (7x + 7) and angle y are alternate exterior angles.
We know that alternate exterior angles are equal.
⇒ (7x + 7) = y
From equation (1),
(7x + 7) + (2x + 2) = 180°
9x + 9 = 180
9(x + 1) = 180
x + 1 = 20
x = 21
This is the required value.
