Answer:
0.097%
Step-by-step explanation:
Since this is a series of events probability question, in order to calculate the probability you need to first find the probability of getting each individual answer right and then multiplying those probabilities together. This will give you the probability of getting 100% on the entire test. Since the questions are multiple-choice with 4 choices and only 1 correct choice then the probability of getting one right is 1/4 or 25%. Now that we have that probability we simply need to multiply it 5 times for each individual question.
1/4 * 1/4 * 1/4 * 1/4 * 1/4 = 1/1024 or 0.0009765 or 0.097%

[tex] \frac{7r}{2} \div \frac{ {14r}^{2} }{3} [/tex]
Answer:
3 / 4r
Step-by-step explanation:
Simplify : 7r/ 2 ÷ 14r²/3
7r/ 2 ÷ 14r²/3
Changing the ÷ sign to multiplication :
Multiply 7r/2 by the reciprocal of the denominator :
7r/ 2 * 3/14r²
((7 * r) / 2) * (3) / 14 * r * r
= 3 / 4r

After a robot vacuum is fully charged, it can run for 15 minutes. It can vacuum 1/2 square foot every second. Can a fully charged robot clean a room that is 400 square feet without recharging?
Answer:
The robot can clean the room without recharging.
Step-by-step explanation:
Given:
After a robot vacuum is fully charged, it can run for [tex]15[/tex] minutes.
The robot cleans [tex]\frac{1}{2}[/tex] square foot every second.
To find: If the charged robot can clean a room that is [tex]400[/tex] square feet without recharging.
Solution:
Area cleaned by the robot in [tex]1[/tex] second [tex]=\frac{1}{2}[/tex] square foot.
We know that, [tex]1[/tex] minute [tex]=60[/tex] seconds.
So, [tex]15[/tex] minutes [tex]=15\times 60=900[/tex] seconds.
Now, area cleaned by the robot in [tex]900[/tex] seconds [tex]=\frac{1}{2} \times 900=450[/tex] square feet.
The area to be cleaned is [tex]400[/tex] square feet.
Hence, the robot can clean the room without recharging.
Jeremy lost his dog, and wants to make some signs to put up in the neighborhood. The cost to make 8 paper signs and 2 laminated signs is $12.00. The cost to make 10 paper signs and 10 laminated signs is $30.00. What is the cost of 1 laminated sign?
Answer:
cost to make paper signs = $1
cost to make laminated signs = $2
Step-by-step explanation:
Let
x = cost to make paper signs
y = cost to make laminated signs
8x + 2y = 12 (1)
10x + 10y = 30 (2)
Multiply (1) by 5
40x + 10y = 60 (3)
10x + 10y = 30 (2)
Subtract (2) from (3) to solve for x
40x - 10x = 60 - 30
30x = 30
x = 30/30
x = $1
Substitute x = 1 into (1)
8x + 2y = 12
8(1) + 2y = 12
8 + 2y = 12
2y = 12 - 8
2y = 4
y = 4/2
y = $2
cost to make paper signs = $1
cost to make laminated signs = $2

5 less than a number x is 3 times the sum of a number x and 2? (i need a word problem not the answer)
Answer:
Yesterday I squeezed 2 kilos of apples in a barrel.
Today I have picked 5 extra kilos of apples and save them in a basket.
By the end of the day, I want to squeeze some of them and add to the barrel.
Apple juice from the barrel is valued 3 times the same amount of raw apples.
I want to find how many apples I can squeeze today (x) such that the value of the remaining raw apples is equivalent to the total value of produced apple juice.
Step-by-step explanation:
The equation is 5-x = 3 * (x + 2).
If x is the amount of apple to squeeze (in kilos) then 5-x is the remaining raw apples and x+2 is the total quantity of juice.
Since that juice is valued 3 times the raw apples we obtain the equivalence defined in the equation above.

A snail crawls 24 inches in 8 minutes.
What is the unit rate of the snail's movement?
The unit rate of the snail's movement is 3 inches per minute.
Unit rate:Important information:
A snail crawls 24 inches in 8 minutes.We need to find the unit rate.
Divide the distance by time to find the unit rate.
[tex]\text{Rate}=\dfrac{24}{8}[/tex]
[tex]\text{Rate}=3[/tex]
Therefore, the unit rate of the snail's movement is 3 inches per minute.

1. Kristen spent $131 on shirts at Target last week. She bought some fancy shirts for
$28 each and then some plain t-shirts for $15 each. If she bought a total of 7 shirts,
then how many of each type of shirt did she buy?
problem #1
problem #2
Answer:
Kristen bought 2 fancy shirts and 5 plain t-shirts.
Step-by-step explanation:
Given that,
Kristen spent $131 on 7 shirts.
Cost of one fancy shirt = $28
Cost of one plain t-shirt = $15
Let,
x be the number of fancy shirts
y be the number of plain t-shirts
x+y = 7 Eqn 1
28x+15y=131 Eqn 2
Multiplying Eqn 1 by 15
15(x+y=7)
15x+15y=105 Eqn 3
Subtracting Eqn 3 from Eqn 2
(28x+15y)-(15x+15y)=131-105
28x+15y-15x+15y=26
13x=26
Dividing both sides by 13
[tex]\frac{13x}{13}=\frac{26}{13}\\x=2[/tex]
Putting x=2 in Eqn 1
2+y=7
y=7-2
y=5
Hence,
Kristen bought 2 fancy shirts and 5 plain t-shirts.

Sasha grew 36 plants with 9 seed packets. How many total seed packets does Sasha
need if she wants to have 76 plants in her backyard in all? Solve using unit rates.
seed packets
Answer:
10 more seed packets.
Step-by-step explanation:
36/9=4 so there are 4 seeds in each packet. If she already has 36 plants, she only need 40 more to get the 76 she wants. 40/4=10 so she needs 10 more seed packets.
