Lortetta and her family are going on vacation. Their destination is 610 miles from their home. Loretta is going to share some of the driving with her dad. Her average speed while driving 55 mph and her dad's average speed while driving is 65 mph. The plan is for Loretta to drive for the first 4 hours of the trip and her dad to drive for the remainder of the trip. Determine th enumber of horus it will take her family to reach their desination.
Answers
Answer: 10 hours
Step-by-step explanation:
First and foremost, we should note that:
Speed = Distance / Time
Total destination = 610 miles
Loretta speed = 55 mph
Time to be used by Loretta = 4 hours
Loretta's distance = Speed × Time = 55 × 4 = 220 miles
The distance to be covered by her dad will then be:
= 610 - 220
= 390 miles
Her dad's average speed = 65 mph.
Time taken by her dad will be:
= 390 / 65
= 6 hours
The number of hours to be used by the family will then be:
Time taken by Loretta + Time taken by her dad
= 4 hours + 6 hours
= 10 hours

during her trip, how many hours does she have left to drive at the same rate ?
Answers
Answer:
bsgdhv is the ghj is the most
Answer:
4 more hours.
Step-by-step explanation:
So, to calculate the remaining time Jill has to drive, we have to first find out how much distance Jill has left to cover:
[tex](450 - 250)[/tex] miles
= [tex]200[/tex] miles
So, at a rate of 50 miles per hour, Jill has to drive:
[tex]\frac{200}{50}[/tex] more hours
= [tex]4[/tex] more hours

Answers
Answer:
Step-by-step explanation:
This is a difference of squares.
√x^2 - √49 is the basic formula for factoring a difference of squares. The idea is that the middle term has been cancelled out.
√x^2 = x
√49 = 7
(x - 7)(x + 7) is the way this factors.
(x - 7)(x + 7)
===========
(x + 7)
The (x +7) in the numerator cancels with the (x + 7) in the denominator.
The answer is (x - 7)
====================================================
She might have wanted you to do it like this.
(x + 7) || x^2 + 0x - 49 || x - 7
x^2 + 7x ........... Subtract
==========
-7x - 49
-7x - 49 ...... Subtract.
=============
0
Or she might have seen you do this
x^2 - 49 x^2 49
======= = === - =====
x + 7 x 7

Option 4 (4, 2, 3)
Step-by-step explanation:
Coordinances for a three-dimensional coordinate system are (x, y, z).
The letter labeling each axis is always on the positive side.
Therefore, all of the coordinances must be positive.
If you look at the x,y plane you can identify that the point is two over on the y axis and four over on the x. You can use this same strategy on the z axis to get the coordinances (4, 2, 3).
Given that (x-1) is the highest common factors of 12 and 30, therefore the value of x is

Kara’s bedroom is in the shape of a rectangle. The perimeter of her room is 50 feet. The width of her room is 12 feet. What is the length of Kara’s room?
A
13 feet
B
25 feet
C
26 feet
D
38 feet
Answers
Answer:
13
Step-by-step explanation:
Ok so we will eliminate some numbers first. The width is 12, but the total on the perimeter is 24. 50-24 = 26
26 is not the length, so divide that by 2, and get 13
Proof:
x=2
13x=26
12x=24
24+26 = 50

Answer:
x = 1/5, y = 6
Step-by-step explanation:
5x + y = 7
y = 7 - 5x
Set equations equal to each other to eliminate y

7 = 25x + 2
5 = 25x
x = 1/5
y = 7 - 5(1/5)

Given the function
Putting all the values of y=9, 6, 0, and -3 to complete the table
FOR y=9
putting y=9
switch sides
subtract 3 from both sides
Hence,
when y=9, x=4
FOR y=6
putting y=6
switch sides
subtract 3 from both sides
Hence,
when y=6, x=2
FOR y=0
putting y=0
switch sides
subtract 3 from both sides
Hence,
when y=0, x=-2
FOR y=-3
putting y=-3
switch sides
subtract 3 from both sides
Hence,
when y=-3, x=-4
Hence, the table becomes:

Answers
Answer:
Plz Brain -list the answer It takes effort tnx dear
Step-by-step explanation:
From given condition
equation of line is given as,
x*cos(α)+y*sin(α)=p
& as tanα= 5/12 so from Pythagoras theorem
sinα= 5/13
cosα= 12/13
⇒12x+5y=39
⇒12x+5y−39=0p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴
HELP PLEASE John opens a savings account with a deposit of $25. After the initial deposit, he deposits $10 each week into his account. Which equation can be used to determine how much money, y, John has after x weeks?
A. y = 35x
B. y = 25x + 10
C. y = 10x + 25
D. y = 10x - 25
Answers
Answer:
C. y = 10x + 25
Step-by-step explanation:
If John put $10 each week but we don't know how many weeks that he deposits $10, use x as the amount of weeks. x10.
There was already $25 in his savings account so we don't have to put an x next to the $25.
