(Simplify your answer.)
Answer:
"bisect" means: angle FGH = angle HGI
(3x-3)=(4x-14)
-3+14=4x-3x
x=11
Angle FGH = (3x-3) = 30
Angle HGI = Angle FGH = 30

A rectangle and a square have equal areas. The length of the square is 9 cm.The rectangle has width 4 cm. What is the perimeter of the rectangular?
Answer:
Perimeter = 26 cm. Area =
Step-by-step explanation:
The rectangle has a width of 4 cm and the square has a length of 9. cm, so to make them have the same area you make the length of the rectangle 9 cm and the square have a width of 4 cm.
then each shape will have two sides that are 9 cm and two sides that are 4 cm.
Perimeter
9 + 9 = 18
4 + 4 = 8
18 + 8 = 26
the perimeter is 26 cm.
Area
9 x 4 = 36
the area is 36 cm.
Answer:
Width is 4cm and length is 20.25, so perimeter is 48.5
Step-by-step explanation:
Square has same length for each side
Area for the Square 9 x 9 = 81
So find another number that adds up to the area of the square
Area for Rectangle 4 x 20.25 = 81
Width for Rectangle is 4cm and length is 20.25, so perimeter is 48.5

Let the function f be defined by the equation
y = f(x),
where x and
f(x)
are real numbers. Find the domain of the function. (Enter your answer using interval notation.)
f(x) = x3 − 5x + 3
Answer:
Domain: [tex](-\infty,\infty)[/tex]
Step-by-step explanation:
The domain of a function is all values of x such that f(x) exists.
In our case we have the following function:
[tex]f(x)=x^{3}-5x+3[/tex]
We know that x and f(x) are real numbers, therefore the domain will be the interval [tex](-\infty,\infty)[/tex], or in other words, the domain is all real numbers.

if tzs 2,500,000 is invested at an interest rate of 9.5%,compounded twice monthly, how long will it take for the investment to reach tzs 7,500,000?
9514 1404 393
Answer:
11 years, 7 months
Step-by-step explanation:
When the investment reaches its desired value, it will be 3 times the original amount. So, we are looking for the number of half-month periods (n) of compounding such that ...
(1 +0.095/24)^n = 3
Taking logarithms, we have ...
n·log(1.003958333...) = log(3)
n = log(3)/log(1.009358333...) ≈ 278.09
This is 278.09/24 ≈ 11.59 years.
It will take about 11 years and 7 months for the investment to reach the desired value.
__
Additional comment
The amount will be about tzs 2,758 short after 11 years 7 months. It will exceed the desired amount after 2 more days' interest is added.

A class fundraiser is earning $7 per car wash w and $4 per cake c sold. The cakes cost $2 to make and the supplies or the car wash cost $1 per car. They will wash less than 50 cars and bake no more than 30 cakes. They want to raise at least $320 to give to a local charity. What system represents this situation
Answer:
w<50
c≤30
6w+2c≥320
Step-by-step explanation:
W stands for the car wash, and C stands for the cakes. Naturally, it would be 7w+4c≥320 but each cake costs $2 to make and each car wash costs $1 per car. This makes the system 6w+2c≥320. They will wash less than(<) 50 cars and bake no more than(≤) 30 cakes. I hope this helped :).
To solve the problem we must know about Expressions.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given to us
Earning per car wash = $7
Earning per cake = $4
Cost of supplies per car wash = $1
Cost of cake = $2
They will wash less than 50 cars and
Bake no more than 30 cakes
They want to raise at least $320
Assumption
Let the number of cakes they sold be represented by x, and the number of car washes they did be represented by y.
Profit from Car washProfit from Car wash
= Earning per car wash - Cost of supplies per car wash
= $7 - $1
= $6
Profit from CakeProfit from Cake
= Earning per Cake - Cost of a cake
= $4 - $2
= $2
What is Total Profit?The system that represents profit
$320 = ($6)y + ($2)x
320 = 6y + 2x
Number of Cake they will bake,As it is given that they will not make more than 30 cakes, therefore,
x ≤ 30
Number of Carwashes they will do,As it is given that they will wash less than 50 cars.
y < 50
Hence, the following equations can represent the system,
320 = 6y + 2xx ≤ 30y < 50Learn more about Expression:

The one-to-one functions g and h are defined as follows.
HELP PLEASE
Answer:
2, (x+13)/6, -7
Step-by-step explanation:
The -1 bit means do it backwards, so look the for the output of the function with the value given.
In g, when we put in 2 we get 9 out, so g^-1(9) is 2.
For the second one we need to rearrange it to get x = something.
h(x) + 13 = 6x
x = (h(x) + 13)/6
Then replace the h(x) with x and the x with h^-1(x) to get
h^-1(x) = (x + 13)/6
The last one is a trick. Note that h and h^-1 are opposites. If we do something then do the opposite of it, we haven't done anything at all! So the number stays the same.

Given that:
Percentage of those having health insurance = 71%
p = 71 / 100 = 0.71
Number of adults selected at random, n = 4
Probability that 4 selected have health insurance :
p^n = 0.71^4 = 0.25411681

1 figure is 10x4(rectangle)
the other figure is a 4x4 square (Note we subtract 8 by 4 because we don't want overlapping area)

A model of a rectangular stove top with four circular burners is shown. The side lengths of the stove top and the diameters of the burners are labeled.
Which measurement is the best estimate of the area in square inches of the stove top that does not include the area of the burners?
A) 108 in.2
B) 492 in.2
C) 420 in.2
D) 528 in.2
The required estimate of the area in square inches of the stove top that does not include the area of the burners is 415 square inches.
What is surface area?Surface area is defined as the measure of a region or surface is called as surface area.
The best estimate of the area of the stovetop that does not include the area of the burners can be obtained by subtracting the total area of the four burners from the total area of the stovetop.
The total area of the stove top is given by the product of its length and width:
Length = 24 inches
Width = 22 inches
Area = Length × Width = 24 × 22 = 528 square inches
The area of each burner is given by the formula for the area of a circle:
= π × (diameter/2)²,
where π is approximately equal to 3.14
Since the diameter of each burner is 6 inches, the radius of each burner is 6/2 = 3 inches.
Area of one burner = Pi × (3)² = 3.14 × 9 = 28.26 square inches
The total area of the four burners is 4 × 28.26 = 113 square
The area of the stove top = 528 - 113
= 415 square inches.
Thus, the required estimate of the area in square inches of the stove top that does not include the area of the burners is 415 square inches.

The price of an item has been reduced by 20% . The original price was $80 . What is the price of the item now?
Answer:
$64
Step-by-step explanation:
80/100=0.8
0.8x20=16
80-16=64
If 0.8 is 1% of the price, then we can multiply it by 20 and get the 16 we need to take off the price. 80-16=64, therefore the new price is $64!
