Answer:
75°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
let x be the sixth angle, then sum and equate to 720°
150 + 100 + 80 + 165 + 150 + x = 720
645 + x = 720 ( subtract 645 from both sides )
x = 75
The sixth interior angle is 75°
x=2
3x+4y=2
-6
4y=-4
y=1
Answer:
x= 1/22 and y=-1/4 (I'm assuming that the equal signs are the only separators of the equation sequence, since there is no indicator that the so-called "sentences" are actually apart.
Find an angle with a positive measure and an angle with a negative measure that is coterminal with each angle 210° and - 120°
Answer:
For angle of 210°, coterminal angles are; 570° and -150°.
For angle of -120°, coterminal angles are; 240° and -480°
Step-by-step explanation:
Since we are asked to angle find angle that's coterminal, we will add/ subtract 360° from each angle respectively to get that because coterminal angles are defined as those that share the same terminal side. Thus;
For angle of 210°, coterminal angles are;
>> 210° + 360° = 570°
>> 210° - 360° = - 150°
For angle of -120°, coterminal angles are;
>> - 120° + 360° = 240°
>> - 120° - 360° = - 480°

f (x) = -|x-5| +3
A)-5
B)3
C)5
D)-1
Answer:
B) 3
Step-by-step explanation:
The (-) represents a flip over the X-Axis.
The |X-5| represents a Horizontal shift right because it's in between the parenthesis.
The 3 represents a positive vertical shift upwards.

Answer:
x = 91
y = 98
Your answer is F.
Step-by-step explanation:
Since a straight angle is 180° you have to subtract 89 from 180 and 82 from 180.
180 - 89 = 91
180 - 82 = 98

Shelby has a $5 gift card to an online music store. She downloads songs that cost $1.20 each. What equation models the total amount of money Shelby spends y if she downloads x songs?
y = 5x + 1.20
y = 5x + 1.20
y = -5x + 1.20
y = -5x + 1.20
y = 1.20x - 5
y = 1.20x - 5
y = 1.20x + 5

Step-by-step explanation:
If 1/8 of my money is $80. What is 50 % of my money
Answer:
$320
Step-by-step explanation:
An easy way to solve this problem is to undo the operations, Find the total amount of money, and then find half of the amount. Since (80) is ([tex]\frac{1}{8}[/tex]) the total amount of money, one has to multiply (80) by (8) to find the total amount of money.
(80) * (8)
= 640
Now one is asked to find (50%) of the money. It is known that (50%) is equivalent to (0.5), therefore multiply (640) by (0.5) to find how much (50%) of the money is.
(640) * (0.5)
= 320
find the value of y.
Answer:
B.) 40°
Step-by-step explanation:
because the sum of all the interior angles should be 180°, so 50°+90°+y=180°
y must equal 40°

A bag contains eight red marbles and 12 green marbles you choose a marble out of the bag without looking what is the probability that you choose a red marble
Answer:
2/5
Step-by-step explanation:
Probability of choosing red = total red marbles / sum of marbles in the bag
sum of marbles in the bag = 12 + 8 = 20
8/20 = 2/5
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

HELPPPPP!!!!!!!!! PLS ! HURRY
Answer:
-2 and 4
Step-by-step explanation:
The zeros of a function are when the function equals 0.
To make (x+2)(x-4) be zero, either the x+2 term or the x-4 term need to be equal to zero. Because any number multiplied by 0 is 0.
So, set x+2=0 solve for x=-2
Set x-4=0 solve for x=4

Answer:
1.) x=-7
2.) x= -8
3.) x=13
4.) x=2
Step-by-step explanation:
ur lucky idc
1. 4x = -28
By dividing both sides of this equation by 4, we see that x = -7.
2. x - (-6) = -2
Note that x - (-6) is equal to x + 6. To solve the equation x + 6 = -2, subtract 6 from both sides to see that x = -8.
3. -x + 4 = -9
First, subtract 4 from both sides to get that -x = -13. Then, multiply both sides by -1 to see that x = 13.
4. -3x + 7 = 1
First, subtract 7 from both sides to get that -3x = -6. Then, divide both sides by -3 to see that x = 2.

THE CORRECT ANSWER is 25 Cm³
Explanation:
Let's consider the vertical block first, having height 8cm, length 1 cm, width 2cm.
Hence the volume of that block = l.w.h = 8×2×1 = 16 cm³
Coming to the horizontal block, having height 3cm, width 3cm, & length 1 cm.
Hence the volume of that block will be = 3×3×1 = 9 cm²
The total volume of irregular figure = Volume of vertical block + horizontal block = 16+9 = 25 cm³

On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Answer:
11.11%
Step-by-step explanation:
The selling price is 250
The cost price is 250-25
= 225
Therefore the gain can be calculated as follows
=250-225x/225x×100
1/9 ×100
= 0.1111×100
= 11.11%
Hence the gain is 11.11%
