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?
Answers
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.

= (30 - 21) / 21 × 100.
= 9/21 × 100
= 42.9%

Answer:
[tex]\frac{4}{15}+\:\frac{1}{2}[/tex] in the simplest term is:
[tex]\frac{4}{15}+\frac{1}{2}=\frac{23}{30}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{4}{15}+\:\frac{1}{2}[/tex]
Thus, solving to reduce to the simplest term
[tex]\frac{4}{15}+\frac{1}{2}[/tex]
LCM of 15, 2: 30
Adjusting fraction based on the LCM
so the expression becomes
[tex]\frac{4}{15}+\:\frac{1}{2}=\frac{8}{30}+\frac{15}{30}[/tex]
Apply the fraction rule: [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]
[tex]=\frac{8+15}{30}[/tex]
Add the numbers: 8+15 = 23
[tex]=\frac{23}{30}[/tex]
Therefore, [tex]\frac{4}{15}+\:\frac{1}{2}[/tex] in the simplest term is:
[tex]\frac{4}{15}+\frac{1}{2}=\frac{23}{30}[/tex]

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

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?
Answers
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

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.

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
Answers
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.
