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

Wednesday morning, the temperature was −12 ∘F. By the afternoon, the temperature was 23 ∘F. Write and then evaluate a subtraction expression to determine the number of degrees of change in temperature between the morning and the afternoon.
The change in temperature between the morning and the afternoon would be 35° F.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
We have been given that Wednesday morning, the temperature was −12° F. By the afternoon, the temperature was 23° F.
We have to determine the change in temperature between the morning and the afternoon
As per the given question,
Here, final temperature = 23° F and initial temperature = −12° F
The change in temperature = final temperature - initial temperature
The change in temperature = 23° F - ( -12° F )
Apply the subtraction operation,
The change in temperature = 23° F + 12° F
The change in temperature = 35° F
Hence, the change in temperature between the morning and the afternoon would be 35° F.

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

Step 3:
∠ABC = 65° Alt. Int. ∠'s ( Alternate Interior ∠'s)
Answer:
B: 65°
Hope This Helps :)
[tex]\tt Step-by-step~explanation:[/tex]
To find the measure of ∠ABC, we need to know that the sum of the interior angles of a triangle is 180º.
[tex]\tt Step~1:[/tex]
Triangle CED has two given angles: 65º and 50º. We can add them together and subtract that from 180 to get the third measure.
[tex]\tt 65+50=115\\180-115=65[/tex]
[tex]\tt Step~2:[/tex]
Since lines AB and ED are parallel, that means m∠ACB is also 65º since the vertical angle is also 65º. Then, we can add 65 and 50 together and subtract that from 180 to get our answer.
[tex]\tt 65+50=115\\180-115=65[/tex]

7 represents the amount of times you moved the decimal
Answer:
The answer is 5.93 x 10 to the power of 7 (10^7)
Step-by-step explanation:
This is the answer because if you take 59,300,000 and then count the digits after 5 you get 7, which then you put the 7 over 10 and put a decimal point in front of the five as showed here 5.93 (Always make sure to put the numbers that are not zero behind the decimal point).

The volume V of a rectangular prism with length l, width w, and height h is v equals l times w times h. What is the width of a rectangular prism with volume 450 cubic inches, length 20 inches, and height 7.5 inches?
Answer:
The answer is 3 inch
Step-by-step explanation:
To start off, the equation you want to use the formula V=whl
Next, you simply plug in the values you already know, so you have 450=w*20*7.5
After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.
