Answer:2.3
Step-by-step explanation:
Cut the the shape into a right triangle and a rectangle
Tri: find measure of the base
sin(45)= opp/hyp
= x/1.8
1.8 *sin (45) = x
x = 1.3
base of tri = 1.3
Area of tri = 1/2bh
1/2(1.3)(1.3)
=0.845
Area of rectangle: 1.1*1.3=1.43
Total area = 1.43+0.845
=2.245
=2.3m^2
Tom bought a pizza. He ate 1/3 of the pizza and gave some of it to his brother. He was left with 1/5 of the pizza. What fraction of the pizza did he give to his brother?
Answer:
2/3 = 10/15
1/5 = 3/15
10/15 - 3/15 = 7/15 of the pizza to his brothers
Find the area of the shaded sector of circle O. Answer in terms of pi
Answer:
40
Step-by-step explanation:
Because 10 times 4 is 56
The shaded region is 1/4 of the whole circle. Thus, the area of the shaded region is 78.5 square units.
What is the area of the sector?Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be
Arc = (θ/2π) πr²
The radius is 10 units and the angle is π/2. Then the area of the shaded region is calculated as,
A = [(π/2)/2π] π x 10²
A = 3.14 x 10 x 10 / 4
A = 78.5 square units
More about the area of the sector link is given below.

The length of the longer piece is 124/7.
What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
let the two pieces be x(longer) and y (shorter)
So,
x+y=31
and, 3x=4y
3x-4y=0
Solving both the equations:
x= 124/7 and y=93/7
Hence, the length of longer piece is 124/7.

Here's a graph of a linear function. Write the
equation that describes that function.
Express it in slope-intercept form.
Answer:
the graph has a positive slope with a y-intercept of 5
y = 1/4x + 5
Step-by-step explanation:
i found the slope by using points (0,5) and (4,6)
slope formula says to subtract the y-values and divide by difference of x-values:
(6-5) / (4-0) = 1/4

Aaron has $35 and a coupon for 35% off for one
item. He wants to buy a new pair of shoes for $41.
Will he be able to get the shoes after the
discount?
Answer:
YES
Step-by-step explanation:
Find 35% of $41. You can basically replace the "of" with multiplication, and then remember that "percent" means "per hundred", so divide 35 by 100.
You will get:
(35/100) x 41
Putting it into decimal form:
0.35 x 41
And you get: $14.35
Remember, you're not done yet, because we have just found the amount of money that will be taken off of the original price. So we have to subtract this from $41.
$41.00 - $14.35 = $26.65
Now compare the prices! Aaron has $35, and with the discount, the shoes will only cost $26.65!
$26.65 is less than $35, so he will be able to get the shoes! Yay for Aaron!

. Is (4,-3) a solution to the following system of equations?
X - y = 4
2x + y = 5
(Use elimination method)
Answer:
No. The correct solution is (3,-1)
Step-by-step explanation:
Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.
Once we do that, we go ahead add the like terms and get 3x = 9
Then, we divide by 3 on each side and get x = 3
Now, we can take that value of x and plugin to any of the original 2 equations we started with.
Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5
Then we solve for y.
2(3) + y = 5
6 + y = 5
6 - 1 = 5
y = -1
There, we found our x value and our y value, (3,-1) :)

Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?
The two populations will be the same after
years.
Answer:
3 years
Step-by-step explanation:
Let y = number of orangutans, and let x = number of years.
For each study, the population, y, after x years is:
First study:
y = 784 - 25x
Second study:
y = 817 - 36x
We set the populations equal and solve for x, the number of years.
784 - 25x = 817 - 36x
Add 36x to both sides. Subtract 784 from both sides.
11x = 33
Divide both sides by 11.
x = 3
Answer: 3 years

P(A) = 3/8P(B) = 2/7(i)
P(A and B) = P(A) * P(B) = 3/8*2/7 = 3/28(ii)
P(A or B) = P(A) + P(B) - P(A and B) = 3/8 + 2/7 - 3/28 = 1/56(21 + 16 - 6) = 31/56(iii)
P(not A and not B) = P(not A) * P(not B) = (1 - 3/8)*(1 - 2/7) = 5/8*5/7 = 25/56Another way:

A silo has a diameter of 50 feet and a height of 30 feet with a cone on top adding another 10 feet of height. What is the volume of the silo.
Answer:
Step-by-step explanation:
Solve this by adding the volume of the cylinder with the volume of the cone. The volume of a cylinder is found from the equation:
pi * r^2 * h
In this case that gives pi * 50^2 * 30 = 75000pi
The area of the cone is found from the equation:
pi * r^2 * h *1/3
In this case you get pi * 50^2 * 10 * 1/3= 8333.pi
Add the two to ger 83333.333*pi ~261799

Samantha wants to know whether the food she serves in her restaurant is within a safe range of
temperatures. She randomly selects 70 entrees and measures their temperatures just before she
serves them to her customers.
What is the population?
Answer: The population would be the data of temperatures of all food served by the restaurant.
Step-by-step explanation:
In a statistical study, the term population refers to the largest group of all individuals related to the study or the objective of the study.
Here, the objective of the study= To check the temperatures of food just before serving.
Population = Data of temperatures of all dishes served by restaurant.
Hence, the population would be the data of temperatures of all dishes served by the restaurant.

Given:
The system of equation is:
[tex]-2x+4y=16[/tex]
[tex]2x+2y=8[/tex]
To find:
The solution of the given system of equations.
Solution:
We have,
[tex]-2x+4y=16[/tex] ...(i)
[tex]2x+2y=8[/tex] ...(ii)
Add (i) and (ii) to eliminate the variable x.
[tex]6y=24[/tex]
[tex]y=\dfrac{24}{6}[/tex]
[tex]y=4[/tex]
Putting [tex]y=4[/tex] in (ii), we get
[tex]2x+2(4)=8[/tex]
[tex]2x+8=8[/tex]
[tex]2x=8-8[/tex]
[tex]2x=0[/tex]
Divide both sides by 2.
[tex]x=0[/tex]
