Answer:
- 4.2 degrees
Step-by-step explanation:
If the drop was from temp 0 at 8 pm to temp -16.8 at midnight (4 hours later)
then,the drop is given by the rate: -16.8/4 = - 4.2 degrees per hour
Therefore, at 9 pm the temperature was:
0 degrees - 4.2 degrees = - 4.2 degrees
The principal on Jan’s loan was $4,700, but by the time she had paid it off after four years, the interest and principal totaled $5,388. If Jan made regular quarterly payments of $355 until the loan was paid off, how much did Jan pay for service charges?
Answer:
$292 in fees
Step-by-step explanation:
First, calculate the total payments Jan made over the 4 years
$355 x 4 payments per year x 4 years = $5,680
Then, calculate the total payments made and subtract the amount of Principal and Interest paid from the total payments made.
$5,680 - $5,388 = $292
$292 is the FEE for the loan
$4,700 is the PRINCIPAL for the loan
$688 is the INTEREST for the loan
Answer:
The answer is 292

Answer:
d(3) = - 25
Step-by-step explanation:
Using the recursive formula with d(1) = 3, then
d(2) = d(1) - 14 = 3 - 14 = - 11
d(3) = d(2) - 14 = - 11 - 14 = - 25
Thus the 3 rd term in the sequence is - 25

solve for y 4y-36x=28
Answer:
[tex]y = 9x + 7[/tex]
Step-by-step explanation:
To solve for y, our goal is to get it isolated on one side of the equation.
[tex]4y - 36x = 28[/tex]
Let's add [tex]36x[/tex] to both sides of the equation.
[tex]4y = 36x + 28[/tex]
Now divide both sides by 4.
[tex]y = 9x + 7[/tex]
Hope this helped!
Answer:
4y-36x = 28........... :4
y-9x = 7
y = 7+9x or y = 9x+7

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 85 miles per hour. The eastbound train travels 105 miles per hour. How long will it take for the two trains to be 456 miles apart? Do not do any rounding.
Answer:
Step-by-step explanation:
We'll make a table for this since we have 2 different trains for which we have formulas. We'll use the distance = rate * time formula, but we have to use it twice because we have 2 trains, then we have to come up with an equation that incorporates both of the distances of the 2 trains to come up with a time. Easy.
d = r * t
East train
West train
Now we can fill in. We know that the rate of the east train is 105 and the rate of the west train is 85, so we fill that in:
d = r * t
East train 105
West train 85
The time is what we are looking for, so that is the unknown for each train:
d = r * t
East train 105 t
West train 85 t
Since the formula is d = rt, we will multiply the rates of each times the time of each and fill in accordingly:
d = r * t
East train 105t 105 t
West train 85t 85 t
Here's an illustration to the best of my abilities in this forum:
<------------------------------|----------------------->
85t 105t
|----------------------456 miles-------------------|
The illustration is supposed to show you that the distance between the trains (456 miles) is found by adding the 2 distances together and solving for t:
85t + 105t = 456
190t = 456 so
t = 2.4 hours

Find the number if:
Step-by-step explanation:
Let the number be x
1 2/3% × x = 4.75
5/3% × x = 4.75
(5/3)/100 × x = 4.75
5/3 × 1/100 × x = 4.75
5x/300 = 4.75
5x = 300 × 4.75
x = (300 × 4.75)/5
x = 1425/5
x = 285
A certain pickup truck gets 20mpg in the city and 28 mpg on the highway. If the driver drives 270 mi on 11 gal of gas, determine the number of city miles and highway miles that the truck was driven
Answer:
95 city and 175 highway miles.
Step-by-step explanation:
The driver gets 20 mpg in city, and 28 mpg on the highway.
An equation that could be written is
20x+28y=270
This equation accounts for the distance traveled.
x+y=11
This equotion accounts for how many gallons were driven.
Multiply the bottom equation by 20, so you can solve the set of equations.
20x+28y=270
20x+20y=220
subtract them
8y=50
y=6.25
now plug this back into x+y=11
x+6.25=11
x=4.75
Now 4.75×20=95 city miles and 6.25×28=175 highway miles.

A delivery company uses cars, cargo vans, and semitrailers. The company uses its cargo vans to deliver packages to locations at a 75-mile radius
from the warehouse. If the distance to the delivery location is within 8 miles of the delivery boundary, a cargo van will still be used. The company
uses the other vehicles for any distance outside this range.
Write an inequality to represent the instances when a vehicle other than a cargo van is used, where x is the distance of a location from the warehouse.
Given that:
The company uses its cargo vans to deliver packages to locations at a 75-mile radius from the warehouse.
If delivery location is within 8 miles of the delivery boundary, a cargo van will still be used.
To find: The inequality to represent the instances when a vehicle other than a cargo van is used.
Solution:
Let x is the distance of a location from the warehouse.
Cargo van will be used if delivery location is within 8 miles of the delivery boundary.
Minimum distance for delivery = 75-8 = 67 miles.
Maximum distance for delivery = 75+8 = 83 miles.
So, the company uses cargo vans for any distance in the range 67 miles to 83 miles. So,
[tex]67\leq x\leq 83[/tex]
Therefore, the required inequality is [tex]67\leq x\leq 83[/tex].

Is 1/4 and 4/16 an equivalent fraction? If so why ?
Answer:
Yes
Step-by-step explanation:
1/4 = 4/16 because 1/4 of 16 is 4
Also,
1/4 is just a simplified version of 4/16
The answer to whether 1/4 and 4/16 are equivalent fractions is that; Yes, they are equivalent fractions
How to simplify Fractions?We have two fractions which are; 1/4 and 4/16
Now, the first fraction is already in simplified form and can't be simplified further. However, the second fraction can be further simplified.
For the second fraction which is 4/16, the numerator and denominators have a common term which is 4. Thus, we can factor it out to get;
(4/4) * (1/4)
4/4 =1 and so we see that 4/16 can be reduced to the first fraction and so they are the same.

Find the critical point of the function f(x) = x2 – 2x + 7.
Answer:
[tex]x=1[/tex] is a critical point of the function [tex]f(x).[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-2x+7[/tex]
Differentiate both sides w.r.t. [tex]x[/tex]
[tex]\Rightarrow f'(x)=2x-2[/tex]
Now, [tex]f'(x)=0[/tex]
[tex]\therefore 2x-2=0[/tex]
[tex]\Rightarrow 2x=2[/tex]
[tex]\Rightarrow x=1[/tex]
Hence, [tex]x=1[/tex] is a critical point of the given function.
Write the equation of a line perpendicular to the line:

Write your answer in slope- intercept form, using reduced fractions for the slope and intercept.
Answer:
y= 4/3x - 8.7777777777(reoccurring)
Step-by-step explanation:
ok for perpendicular slopes we use the negative reciprocal of the original slope so -3/4 turns into 4/3. next we take the equation y = 4/3x + b and plug in -1 for x and -10 for y to find B.
