what is the sum of the measures of the interior angles of a hexagon
Answer:
Hexagon has 6, so we take 540+180=720. A heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees.

Maria is solving this number riddle by using guess and check: Fifteen less than a number is twelve. Based on the riddle, which statements must be true? Check all that apply. Less than means subtraction. Subtract 15 from the unknown number to get 12. 15 minus 12 = 3 The unknown number is 27. 15 + 3 = 18 27 minus 12 = 15 This is an addition problem.

Find the perimeter and the area of the polygon with the vertices: (-1, -2), (-6, -2), (-6, -8), (-1, -8)
Answer:
a) The perimeter of the rectangle =
= 22 units
b) The area of the rectangle
= 30 square units
Step-by-step explanation:
We solve the above question using the formula
= √(x2 - x1)² + (y2 - y1)²
When we are given vertices (x1, y1) and (x2, y2)
The vertices: (-1, -2), (-6, -2), (-6, -8), (-1, -8)
We have to find the length of the sides
Side A
(-1, -2), (-6, -2)
= √(-6 - (-1))² +( -2 -(-2))²
= √-5² + 0²
= √25
= 5 units
Side B
(-6, -2), (-6, -8)
= √(-6 - (-6))² + (-8 - (-2))²
= √(-6 +6)² + (-8 +2)²
= √0² + -6²
= √36
= 6 units
Side C
(-6, -8), (-1, -8)
= √(-1 - (-6))² +(-8 - (-8))²
= √(-1 + 6)² + (-8 + 8)²
=√ 5² + 0²
= √25
= 5 units
Side D
(-1, -2), (-1, -8)
= √(-1 -(-1))² + (-8 - (-2))²
= √(-1 + 1)² + ( -8 + 2)²
= √0 + -6²
= √0 + 36
= √36
= 6 units
From the above calculation,
Side A = Side C = 5 units
Side B = Side D = 6 units
Hence, this polygon is a quadrilateral called the RECTANGLE.
Therefore:
a) The perimeter of the rectangle =
2L + 2W
= 2(5) + 2(6)
= 10 units + 12 units
= 22 units
b) The area of the rectangle
= Length × Width
= 5 units × 6 units
= 30 square units

The measures of angles A and B are equal and complementary. What is the measure Of each angle?
Answer:
45
Step-by-step explanation:
if they're both the same number and complimentary (adding up to 90) it'd be 90/2, which is 45.
The measure of each angle is 45 degrees.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If two angles are complementary, it means that they add up to 90 degrees.
Let the measure of angle A be x degrees.
Then, the measure of angle B is also x degrees since they are equal.
Now,
Angle A + Angle B
= x + x
= 2x
The sum of the two angles is equal to 90 degrees.
So,
Angle A + Angle B = 90
Substituting this into the previous equation,
2x = 90
Dividing both sides by 2.
x = 45
Therefore,
The measure of each angle is 45 degrees.

There are 10 chocolates in a box.
7 of the chocolates have soft centres and 3 of the chocolates have hard centres. Kyla takes at random a chocolate from the box and eats it.
She then takes at random another chocolate from the box and eats it.
The probability of getting chocolates with harder center is 7/15.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, there are 10 chocolates in a box. 7 of the chocolates have soft centers and 3 of the chocolates have hard centers.
Probability of choosing first chocolate with hard center is
Total number of outcomes =10
Number of favorable outcomes =7
Now, probability is 7/10
Probability of choosing second chocolate with hard center is
Total number of outcomes =9
Number of favorable outcomes =6
Now, probability is 6/9
Probability of an event = 7/10 × 6/9
= 7/10 × 2/3
= 7/5 × 1/3
= 7/15
Therefore, the probability of getting chocolates with harder center is 7/15.

find the 9th term for 150,60,24
Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304
In AEFG, the measure of ZG=90', the measure of ZE=51°, and FG = 5.2 feet. Find
the length of EF to the nearest tenth of a foot.
Answer: 6.7 feet
Step-by-step explanation: sin 51= 5.2/x
xsin51= 5.2
xsin 51/sin 51 = 5.2/sin 51
x= 5.2/sin 51 =6.6911≈ 6.7 feet

The equation of the piecewise function f(x) is below. What is the value of f(3)?
Answer:
5
Step-by-step explanation:
Ask your self which equation you should use. Since it says F(3) then we have to find an equation that would fit this correctly. For example if we look at -X^2, X<-2 we could see that 3 is clearly not less than -2, leading to the conclusion that this is not the right equation.. If you look at the last equation it says that x has to be greater/equal to 0 which is true. So then we are left with the equation...
F(3)=x+2
F(3)=3+2
F(3)=5

Serena makes 2 1/4 cups of popcorn using 1 1/2 tablespoons of kernels. She wants to know how many tablespoons of kernels to use to make 6 cups of popcorn
Answer:
about 4
Step-by-step explanation:
just guessed
The number of tablespoons of kernels to use to make 6 cups of popcorn will be 4 tablespoons. Option B is correct.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Serena makes 2 1/4 cups of popcorn using 1 1/2 tablespoons of kernels.
Convert the mixed fraction into a fraction number. Then we have
2 1/4 = 9/4
1 1/2 = 3/2
The ratio of cups of popcorn and tablespoons of kernels will be constant.
The number of tablespoons of kernels to use to make 6 cups of popcorn will be given as,
K / 6 = (3/2) / (9/4)
K = 4 tablespoons
The number of tablespoons of kernels to use to make 6 cups of popcorn will be 4 tablespoons. Option B is correct.
