Answer:
25 dollars
Step-by-step explanation:
If 20 percent of the initial price was 5, you can create the equation:
0.2x=5, with x being the regular price.
Multiply both sides by 5:
x=25
Answer:
25$
Step-by-step explanation:
20/100 can be rounded down to 1/5 meaning all you have to do is multiply 5 by 5
5 times 5 is 25
25$ was the original price

a mercury thermometer records a temperature of 8 degrees fahrenheit at 10 a.m. if the temperature drops by 3 degrees fahrenheit every hour what will be the temperature by 2 p.m. of the same day
Answer:
-4 Degrees Fahrenheit
Step-by-step explanation:
Given
[tex]Initial\ Temperature = 8[/tex] ---- at 10am
[tex]Difference = -3[/tex]
Required
Determine the final temperature at 2pm
First, we need to determine the hour from 10am to 2pm (Both inclusive)
[tex]Interval = 2pm - 10am + 1hr[/tex]
[tex]Interval = 4hr + 1hr[/tex]
[tex]Interval = 5hr[/tex]
To solve further, we make use of the following Arithmetic Progression formula:
[tex]T_n = a + (n - 1)d[/tex]
Where
[tex]a = 8[/tex] --- Initial
[tex]d = -3[/tex] --- difference
[tex]n = 5[/tex] -- 5th term
[tex]T_n[/tex] --- Final temperature at 2pm
So: we have:
[tex]T_n = 8 + (5 - 1) * -3[/tex]
[tex]T_n = 8 + (4) * -3[/tex]
[tex]T_n = 8 + 4 * -3[/tex]
[tex]T_n = 8 -12[/tex]
[tex]T_n = -4[/tex]
Hence:
The temperature is -4 Degrees Fahrenheit
which relation is a function of x
Answer:
f(x)=y.
Explanation
In a function, f(x) means "the function of x". For example, f(x)=2x is the same thing as y=2x. But f(y) would be something different entirely, because that would be using the function definition to change the y-value.

What number equals -4 and 2
Answer:
is there a graph or any other options to go with this?
Step-by-step explanation:
for a small party of 12 people, the caterer offered a choice of a steak dinner for $12:00 per or a chicken dinner for $10.50 the final cost for the meals was 138:00. how many of each was ordered?
Answer:
let the $12 dish be x and the other y
x + y = 12 <--- 1
12x + 10.50y= 138 <--- 2
multiply equation 1 by 12
so now we have
12x + 12y = 144
12x + 10.50y = 138
now subtract each one and that cancels out x
1.5y = 6
y = 4
now subsitute that into any equation
x + 4 = 12
x = 12 - 4
x = 8

if x equals 3 cubed what does this problem equal 2x= If x = 33:
2x = ?
Answer:
2x = 54
Step-by-step explanation:
The given information;
x = 3^3
solve
x = 27
(beacuse 3^3 = 3 * 3 * 3 = 27
find 2x:
2x = 2 * x
x= 27
2 * 27 = 54
2x = 54
Andre is buying snacks for the track and field team. He buys a pound's of apricots for $6 per pound and b pounds of dried bananas for $4 per pound he buys a total of 5 pounds of apricots and dried bananas and spends a total of $24.50 Which system of equations represents the constraints in the situation?
Answer:
a + b = 5 ...........1
6a + 4b = 24.50 ......... 2
Step-by-step explanation:
Let a be the amount of pounds of apricot bought
Let b be the amount of pounds of banana bought
If he buys a total pounds of 5 pounds then;
a + b = 5 ...........1
Also if a pound's of apricots for $6 per pound, total amount of aprciots bought will be $6a
Also if b pound's of banana is for $4 per pound, total amount of banana bought will be $4b
If he spends a total of $24.50 on both banana and apricots, then:
6a + 4b = 24.50 ......... 2
The system of equations that represents the constraints in the situation is:
a + b = 5 ...........1
6a + 4b = 24.50 ......... 2
Answer: C

N entry level technical writer's annual pay is $55,068 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it employs its technical writers. If the firm cuts the work year to 51 weeks but keeps the same rate of pay, how much should the technical writer expect his annual pay to decrease? Round your answer to the nearest dollar.
Answer:
The technical writer should expect his annual pay to decrease by $1,059
Step-by-step explanation:
52 weeks = $55,068
51 weeks =
Cross Multiply
51 weeks × $55,068/52 weeks
= $54009
The writer will be paid $54009 for 51 weeks
His pay reduced by:
$55,068 - $54,009
= $1,059
Question 1: On a coordinate plane, triangle ABC has vertices at A(10,5), B(10,15), and C(5,5). Triangle A'B'C' has vertices at A' (30,12), B'(30,52), and C(10,12). Which transformation maps triangle ABC onto triangle A'B'C'? A. (x,y) --> (3x, 3y + 3) B. (x,y) --> (4x - 10, 4y - 8) C. (x,y) --> (4x + 10, 4y + 8) D. (x,y) -> (3x, 3y - 3)
Answer:
B. (x,y) --> (4x - 10, 4y - 8)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.
If a point X(x, y) is translated a units right and b units up, the new location is (x + a, y + b) also If a point X(x, y) is translated a units left and b units down, the new location is (x - a, y - b)
If a point X(x, y) is dilated by the factor k the new location is X'(kx, ky).
Triangle ABC has vertices at A(10,5), B(10,15), and C(5,5), If it is dilated by a factor of 4, the new location is A*(40, 20), B*(40, 60) and C*(20, 20). If then a translation of 10 units left and 8 units down, the new points are A'(30, 12), B'(30, 52), C'(10, 12).
This is a transformation of (x,y) --> (4x - 10, 4y - 8)

Which of the following equations defines a line that passes through the point (8,2) and is perpendicular to the line y= -2x + 4?
Answer:b
Step-by-step explanation:
I plugged all of these into a graph and the used the graph trace feature (after setting the step to 1) and traced all of the graphs to find if they hit the point (8,2). B-d do so we can eliminate a and then you can either graph the line y=-2x+4 or just go with b because they have the same slope (-2x). Hope that helps!

2. A package delivery service has a truck that can hold 4200 pounds of cargo
and has a capacity of 480 cubic feet. The service handles two types of
packages: small, which weigh up to 25 pounds each and are no more than 3
cubic feet each; and large, which are 50 pounds each and are 5 cubic feet
each. The delivery service charges $5 for each small package and $8 for each
large package. Let x be the number of small packages and y be the number of
large packages in the truck. What is the maximum revenue per truck?
Answer:
$680
Step-by-step explanation:
Capacity of the truck: 4200 pounds and 480 cubic feet of cargo.
Small package: 25 pounds and 3 cubic feet each.
Large package: 50 pounds and 5 cubic feet each.
For x number of small packages:
25x pounds and 3x cubic feet
Let x = 8,
200 pounds and 24 cubic feet.
For y number of large packages:
50y pounds and 5y cubic feet
Let y = 80,
4000 pounds and 400 cubic feet.
Since delivery service charges $5 for each small package and $8 for each large package.
The maximum revenue per truck = ($5x + $8y)
= ( $5 x 8) + ($8 x 80)
= $680
