jayden and chandra are cleaning the house. it has 12 rooms, and each room is about the same size. when jayden cleans by himself, it takes him 6 hours. when chandra cleans by herself, it takes her 12 hours. when they clean the house together, they finish in 4 hours. when they work together, how many rooms does jayden clean and how many does chandra clean?
Jayden's work rate is twice Chandra's work rate, and, the rooms cleaned
by Jayden is twice the number of rooms cleaned by Chandra.
Response:
Jayden cleans 8 rooms while Chandra cleans 4 roomsWhich method can be used to find the number of rooms cleaned by Jayden and Chandra?Number of rooms in the house = 12
The time that Jayden takes to clean the house = 6 hours
Time that it takes Chandra to clean the house by herself = 12 hours
Time it takes both of them to clean the house = 4 hours
Required:
The number of rooms that Jayden clean and the number of rooms that
Chandra cleans when they work together.
Solution:
Given that the time it takes Jayden to clean the house is half the time
taken by Chandra.
Therefore;
The number of rooms Jayden cleans in 4 hours is twice the number of rooms cleaned by Chandra, which gives;
Ratio of the number of rooms cleaned by Jayden to the number cleaned by Chandra is 2 : 1
Total number of rooms cleaned = 12
[tex]Number \ of \ rooms \ cleaned \ by \ Jayden = \dfrac{2}{2 + 1} \times 12 = \underline{8 \ rooms}[/tex]
The number of rooms cleaned by Chandra = 12 - 8 = 4 rooms

Mr.cheeks collects 95 strawberries to feed his family. He provides the same number of strawberries to each of his 6 hamster children. After giving out as many strawberries as possible, how many will mr. Cheeks have leftover for himself
Answer:
Each Children gets = 15 strawberry
leftover for Mr.Cheek = 5 strawberry
Step-by-step explanation:
Given;
Mr.cheeks collects 95 strawberries to feed his family.
He provides the same number of strawberries to each of his 6 hamster children.
To Find;
After giving out as many strawberries as possible, how many will mr. Cheeks have leftover for himself
Solve;
Since, Mr.cheeks total strawberries is 95 and he has 6 hamster children
we have to divide to see how much each children gets
95/6 = 15 with 5 remainder.
Hence, we can conclude that each children gets 15 and Mr.Cheeks have 5 leftover for himself

A rectangular box is 5 cm long and 6 cm wide. How many cubical packets each of 1 cm^3 can be placed on the floor of its base? If 10 layers of such packets are placed on the floor, how many packets are there?
a. The number of cubical packets on the floor is 30.
b. the number of cubical packets in 10 layers is 300 layers.
Length of cubical packetSince the volume of each cube is 1 cm³ and the volume of a cube V = L³ where L = length of side,
So, L = ∛V = ∛1 cm³ = 1 cm
So, the sides of the cubes are 1 cm long
Volume of layerAlso, since the rectangular box is 5 cm long and 6 cm wide, to find the number of 1 cm³ cubical boxes that can be placed on the floor, we find the volume of that layer which is V = 5 cm × 6 cm × 1 cm = 30 cm³
Number of cubical packets on the floorThe number of cubical packets on the floor is 30.
So, the number of cubical packets required, n = volume of layer/volume of cubical packet
= 30 cm³/1 cm³
= 30
The number of cubical packets on the floor is 30.
b. Number of cubical packets in 10 layersThe number of cubical packets in 10 layers is 300 layers.
If there are 10 layers, then the number of packets on the layers, N = number of layer × number of packets/layer
= 10 × 30
= 300 layers.
So, the number of cubical packets in 10 layers is 300 layers.

Answer:
x = 9
y = 13
Step-by-step explanation:
Side-Side-Side or SSS means that if all three sides of one triangle are equal to all three corresponding sides of another triangle, then the two triangles are considered to be congruent (equal).
Therefore, GH = PM ⇒ 7x + 8 = 6y - 7
and, GP = HM ⇒ 8x - 10 = 5y - 3
Rewrite the first expression to make x the subject, then substitute this into the second equation, and solve for y:
GH = PM
⇒ 7x + 8 = 6y - 7
⇒ 7x = 6y - 15
⇒ x = (6/7)y - 15/7
Substituting x = (6/7)y - 15/7 into GP = HM:
GP = HM
⇒ 8x - 10 = 5y - 3
⇒ 8[(6/7)y - 15/7] - 10 = 5y - 3
⇒ (48/7)y - 120/7 - 10 = 5y - 3
⇒ (13/7)y = 169/7
⇒ y = 13
Now we have found a value for y, substitute this into one of the expressions and solve for x:
8x - 10 = 5y - 3
⇒ 8x - 10 = (5 x 13) - 3
⇒ 8x - 10 = 62
⇒ 8x = 72
⇒ x = 9

Step-by-step explanation:
Simplify the roots, and simplify the fraction.
For example, for x=(-4±√48)/4, you can simplify √48 to be √16 * √3, which is just 4·√3 or 4√3. Now, the original fraction is (-4±4√3)/4, which can be simplified to -1±√3. Solve the other problems using the same method.

One customer is chosen at random for a prize giveaway. (Round answers to 4 decimal places.)
a. What is the probability that the customer is at least 20 but no older than 59?
b. What is the probability that the customer is either older than 60 or younger than 40?
c. What is the probability that the customer is at least 60?
Using it's concept, it is found that the probabilities are as follows:
a) 0.6637.
b) 0.6947.
c) 0.1527.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, there is a total of 83 + 63 + 99 + 65 + 73 + 69 = 452 customers.
Item a:
63 + 99 + 65 + 73 = 300 are at least 20 but no older than 59, hence:
p = 300/452 = 0.6637.
Item b:
83 + 63 + 99 = 245 are younger than 40.
69 are older than 60.
Hence:
p = (245 + 69)/452 = 0.6947.
Item c:
69 customers are at least 60, hence:
p = 69/452 = 0.1527.

she earns 7.80 an hour for mowing and 7.60 for babysitting so
6 hours of mowing that is 7.80 x 6 which is $46.8
and 1 hour of babysitting is $7.60 so we add up which is $54.40 in total
Answer:
$54.40
Step-by-step explanation:
You do 7.80*6=46.80 and 760*1=7.60 then add 46.80+7.60=54.40.

Use the distance formula to find the distance, to the nearest tenth, between F(10,5) and G(-1,2)
Step-by-step explanation:
the distance formula
d = sqrt((x2 - x1)² + (y2 - y1)²)
is simply based on the Pythagoras formula
c² = a² + b²
or
c = sqrt(a² + b²)
because the distance between 2 points is the Hypotenuse of a right-angled triangle with the legs being the x coordinate difference and the y coordinate difference of the 2 points.
so, in our case here
d = sqrt((10 - -1)² + (5 - 2)²) = sqrt(11² + 3²) = sqrt(121 + 9) =
= sqrt(130) = 11.40175425... ≈ 11.4
