Find the surface area of the prism.
Answers
Answer:
2880
Step-by-step explanation:
The base is made up of two triangles and a square, if that makes sense. Finding the area of a triangle is (base x height)/2.
The base of the tiny triangle is 4 because there is 8 inches extra to the 10 inch square. 10 x 4 = 40.
Now we have a 10 by 10 square: 10 x 10 = 100.
So, the area of the trapezoid is 140. There are two trapezoids in this prism, so both bases are 280.
The surface area of the sides are solved by 12 x 50 = 600. Together, the sides equal 1200.
The top is solved by 10 x 50 = 500.
The bottom is solved by 18 x 50 = 900.
Add them all together: 280 + 1200 + 500 + 900 = 2,880

What point is symmetric to (2,7) on this quadratic graph?
OPTIONS
• (-5,0)
• (-2,4)
• (2,-1)
• (-6,7)
Answers
Answer: (-6,7)
Step-by-step explanation:
Tow points, (x1, y1) and (x2, y2) are simetric in a quadratic graph when:
f(x1) = y1 = f(x2) = y2
so y1 = y2
Then if we have the point (2,7) we want to find other point that has the same value for y, this is (-6, 7)
So the correct option is (-6,7)

Step-by-step explanation:
Step 1: Answer the question
This algebraic expression is not a polynomial therefore, none of these options match except D. The reason why it is not a polynomial is because there is a 7^x which is not a polynomial expression. The expression needs to be expressed as a 7x^2 + 2x + 1. Therefore, the answer is D.

Answers
Answer:
(D)$81
Step-by-step explanation:
Given that the number of purses a vendor sells daily has the probability distribution represented in the table.
Expected Value, [tex]E(x)=\sum_{i=1}^{n}x\cdot p(x)[/tex]
Therefore:
[tex]E(x)=(0X0.35)+(1X0.15)+(2X0.2)+(3X0.2)+(4X0.03)+(5X0.07)\\=0+0.15+0.4+0.6+0.12+0.35\\E(x)=1.62[/tex]
If each purse sells for $50.00, the number of expected daily total dollar amount taken in by the vendor from the sale of purses
=Expected Value X $50
=1.62 X $50
=$81

Step-by-step explanation:
The solution of number is, 200.
We have to given that;
To find a number which is 30% of number is 60.
Let us assume that,
A number is, x
Hence, We can formulate;
⇒ 60 = 30% of x
⇒ 60 = 30/100 × x
⇒ 60 = 3x / 10
⇒ 600 = 3x
⇒ 3x = 600
⇒ x = 200
Thus, The solution of number is, 600

A delivery service claims that orders arrive before noon 90% of the time. If Amy uses the delivery service 20 times, how many times can she predict the deliveries will arrive before noon? Is the claim accurate if her packages arrive after noon 4 times?
Answers
Answer:
They claim that 90% of the times, the orders arrive in time.
Then, out of N orders, (90%/100%)*N of them will arrive in time.
Here we have that N = 20
then the number that arrives in time is:
(90%/100%)*20 = 18
Now, experimetally we see that 4 times her packages arrived after noon (so 16 times the packages arrived in time), so we can calculate the experimental percentage as:
(X/100%)*20 = 16
X = (16/20)*100% = 80%
so the percentages doesn't match, so it the claim is not really accurate, but this is a small sample, so if the number of times that she uses the delivery increases, we may see that the experimental percentage gets closer to the claimed percentage.

Terry scored 71, 80, and 86 on his first three history tests. What must terry score on the fourth test to have a mean of exactly 80
Answers
Answer:
83
Step-by-step explanation:
You are trying to find the score that gives you a specific mean. A mean is calculated by dividing the sum of the data by the amount of data. Set up in this order, with x as the fourth score, to find the answer.
[tex]\frac{71+80+86+x}{4}=80\\\frac{237+x}{4} =80\\237+x=320\\x=83[/tex]
The fourth test score must be an 83.
Answer:
83
Step-by-step explanation:
Equation: 71 + 80 + 86 + x / 4 = 80
Add 71, 80, and 86 together.
237 + x = 80
Multiply 4 to both sides (cross multiplying).
237 + x = 320
Subtract 237 from both sides.
x = 83

The required inequality that contains -25 in its solution is y +20 > -30.
Option D is correct.
Number of inequality is given y + 11 > -9 , y - 17≤ -46, 30 ≤ y + 5, y + 20 > -30, the inequality that contains -25 to its solution of set to be determine.
What is inequality?Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
1) y + 11 > -9
y >-20
It does not contain -25. in its solution set.
2) y - 17≤ -46
y ≤ -29
It does not contain -25. in its solution set.
3) 30 ≤ y + 5
25 ≤ y
It does not contain -25. in its solution set.
4) y + 20 > -30
y > -50
It does contain -25 in its solution.
Thus, the required inequality that contains -25 in its solution is y +20 > -30.

Elana is programming a video game. She needs to simulate the power up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 - 100. Elana wants the best power up to be rewarded 15% of the time. Explain how Elana can use the computer to simulate the player getting the best power up at least 2 out of 3 times
Answers
Answer:
You have to define when the power should be pushed up using the 'For' statement and let an impulse be sent to the CPU to increase power by 15%
Step-by-step explanation:
We use certain functions in writing computer programs.
For the 'For' statement ; we can define conditions. First Elana would define at what point does she want the player power to get the best power.
For example if she defines that when the player has played for 2hours return an integer 1 for instance.
This value returned will now send a pulse to the CPU to increase its power to 15%.
If the player plays for further 1hour she can define the count to be 10 and so send another pulse to the CPU to increase the processing power by additional 15%

A canvas shopping bag has a mass of 600 grams. When 5 cans of equal mass are put into the bag, the filled bag has a mass of 4 kilograms. What is the mass of each can in grams?
Answers
Answer:
Mass of each can = 680 grams
Step-by-step explanation:
Mass of a canvas shopping bag = 600 grams Or [tex]\frac{600}{1000}[/tex] Kilograms
= 0.6 Kilograms
Let the mass of each can = w Kilograms
Then the mass of 5 cans = 5w Kilograms
Total mass of the bag when these cans were kept in the bag = 4 Kilograms
(5w + 0.6) = 4
5w + 0.6 - 0.6 = 4 - 0.6
5w = 3.4
w = [tex]\frac{3.4}{5}[/tex]
= 0.68 Kilograms
= [tex]0.68\times 1000[/tex]
= 680 grams
Therefore, mass of each can = 680 grams
