Answer:
B
Step-by-step explanation:
LaTanya leaves her house at 12:30 P.M. and bikes at /12 miles per h to Marta’s house. She stays at Marta’s house for 90 min. Both girls walk back to LaTanya’s house along the same route at ./.2.5 miles per h They arrive at LaTanya’s house at 3:30 P.M. How far is Marta’s house from LaTanya’s house?
Marta's house is 3.10 miles from Latanya's house
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
Given that Latanya leaves her house at 12:30 p.M. She bikes at 12 mi/hr to Marta's house She stays at Marta's house for 90 minutes Both girls walk back to Latanya's house at 2.5 mi/h They arrive at Latanya's house at 3:30 p.M.
We need to know how far is Marta's house from Latanya's house
∵ Latanya starts her trip at 12:30 p.M.
∵ She returns home at 3:30 p.M.
∴ The time of her trip is → 3:30 - 12:30 = 3 hours
- But she stays at Marta's house for 90 minutes
∵ 1 hour = 60 minutes
∴ 90 minutes = 90 ÷ 60 = 1.5 hours
∴ The time from her house to Marta's house and from Marta's house to her house is → 3 - 1.5 = 1.5 hours
Assume that the distance from her house to Marta's house is d and the time from her house to Marta's house is t₁ and the time from Marta's house to her house is t₂
∵ Latanya bikes at 12 mi/h to Marta's house
∵ Distance = speed × time
∴ d = 12 × t₁
∵ Both girls walk back to Latanya's house at 2.5 mi/h
∴ d = 2.5 × t₂
Equate the two expressions of d
∴ 12 = 2.5 ⇒ (1)
∵ t₁ + t₂ = 1.5
Subtract from both sides
∴ t₂ = 1.5 - t₁ ⇒ (2)
Substitute equation (2) in equation (1)
∴ 12t₁ = 2.5(1.5 - t₂ )
∴ 12 = 3.75 - 2.5
Add 2.5 t₁ to both sides
∴ 14.5t₁ = 3.75
Divide both sides by 14.5
t₁ = 15 / 38 hour
∴ She spends 15/58 hours biking Marta's house. Let's find d
∵ d = 12t₁
∴ d = 12 x ( 15 / 38 ) miles
Therefore, Marta's house is 3.10 miles from Latanya's house

Step-by-step explanation:
because if you do 5/10-3/10 you get 2/10
then you simplify by 2 which means you do 2 divided by 2 which
is 1 then you do 10 divided by 2 which is equal to 5 so your
answer is indeed 1/5

The value of x from the given ratios 2 2/7 :(0.6x)= 4/21 :0.25 will be 5.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
[tex]2 \frac{2}{7}[/tex] :(0.6x) = 4/21 :0.25
Therefore, solve the mixed fraction, we get
16/7 :(0.6x) = 4/21 :0.25
Step 1: Simplify both sides of the equation.
16/7 :(0.6x) = 4/21 :0.25
(16/7) / (0.6x) = (4/21 ) / (0.25 )
Step 2: Divide both sides
(16/7) / (0.6x) = (4/21 ) / (0.25 )
Cross multiply:
(16/7) x (0.25 )= (4/21 ) x (0.6x)
4/7 = 2.4x /21

Divide both sides by 16.8:

Answer: 12.9
Step-by-step explanation:
Change each proportion so that it is __ kg = 1 pound and __ stone = 1 pound. Once you do this you should get that 0.45 kg = 1 pound and 0.07 stone = 1 pound. Then, you set up another proportion using these conversions, which would be 0.45 kg over 0.07 stone is equal to 83 kg over x stone. Once you solve for x, you get the answer of 12.9

Quiana took out a loan to pay for a new car. Initially, she owed the lender $15,234.68. She has repaid $247.43 of the loan each month for the past 5 months. What is the net change to the loan from Quiana’s perspective over the past 5 months?
Write a rational number to express the initial loan amount as it relates to Quiana’s bank account.
Initial amount of loan = $15,234.68
Monthly payment = $247.43
Number of months = 5
Required Information:
Net change in loan = ?
Answer:
Net change in loan = $1,237.15 = $1,237(3/20)
Step-by-step explanation:
Quiana owed her lender an amount of 15,234.68 initially, she repaid the lender each month with an amount of $247.43 for 5 months, so the total amount that she repaid is
Total amount repaid = Monthly payment*Number of months
Total amount repaid = $247.43 × 5
Total amount repaid = $1,237.15
The remaining owed amount is given by
Balance = Initial amount of loan - Total amount repaid
Balance = $15,234.68 - $1237.15
Balance = $13,997.53
So the net change to the loan from Quiana's perspective over the past 5 months is,
Net change in loan = Initial amount of loan - Balance
Net change in loan = $15,234.68 - $13,997.53
Net change in loan = $1,237.15
or
Net change in loan = $1,237(3/20)
Therefore, the net change to the loan from Quiana's perspective over the past 5 months is $1,237.15
