Marsha buys x pens at $0.70 per pen and one pencil for $0.10. Which function gives the total amount Marsha spends? A C(x) = (0.70+ 0.10)x B C(x) = 0.70x + 0.10 C(x) = 0.70x + 10 C(x) = 0.70x + 0.10x
Answer:
B C(x) = 0.70x + 0.10
Step-by-step explanation:
Number of pens = x
Cost of pens = $0.70
Number of pencil = 1
Cost of pencil = $0.10
Total cost, C(x) = (Number of pens * Cost of pens) + (Number of pencil * Cost of pencil)
= (x *0.70) + (1 * 0.10)
= 0.70x + 0.10
C(x) = 0.70x + 0.10
The answer is
B C(x) = 0.70x + 0.10
Mary brought $20 to the skating rink. She paid $5.50 admission and $3.75 to rent skates. She also purchased two bottles of water for $1.25 each, and a snack for $2.75. Which expression can be used to determine how much money Mary has left? How much money does Mary have left?
Answer:
Amount left = $5.5
Step-by-step explanation:
Given:
Total amount = $20
Spend for admission = $5.50
Spend for rent = $3.75
Spend for 2 bottle = $1.25 each
Spend for snack = $2.75
Find:
Amount left
Computation:
Amount left = Total amount - Spend for admission - Spend for rent - Spend for 2 bottle - Spend for snack
Amount left = $20 - $5.5 - $3.75 - 2($1.25) - 2.75
Amount left = $5.5
Answer:
Amount left = $5.5

You are offered two different sales jobs. The first company offers a straight commission of 7% of the sales. The second company offers a salary of $ 330 per week plus 3% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good?
Answer:
you must make 8250 sale in a weekStep-by-step explanation:
let the number of sale be x
let the total amount earned be y
The first job
7% of x= 0.07x
y=0.07x----------------1
The second job
$330
3% of x= 0.03x
y=330+0.03x-------------2
equating 1 and 2 we have
0.07x=330+0.03x
solving for x we have
330=0.07x-0.03x
330=0.04x
divide both sides by 0.04 we have
330/0.04=x
x=8250
you must make 8250 sale in a week
please help!!! thank you
Answer:
WX = 18
Step-by-step explanation:
This is just a simple 1:2 congruency.
We know that because side FD is equal to 7 and side XY is equal to 14.
7:14 is the same as 1:2.
Using that logic we can then apply it to side FE.
Multiply 9 by 2 and you'll get your answer of WX = 18.
Find the slope and y-intercept of y=1/5x+4 o
Answer:
The Y-intercept of y=1/5x+4 would be y=4. And the X-intercept would be x=-20
Step-by-step explanation:
the slope (m) of the line y = (1/5)x + 4 is 1/5, indicating an upward slope, and the y-intercept (b) is 4,
In the equation y = (1/5)x + 4, the coefficient of x, 1/5, represents the slope of the line. The slope (m) is the ratio of the vertical change to the horizontal change between any two points on the line. In this case, the slope is 1/5, which means that for every unit increase in x, the y-value increases by 1/5.
The constant term, 4, represents the y-intercept (b). The y-intercept is the point where the line intersects the y-axis. In this equation, the y-intercept is 4, which means that the line crosses the y-axis at the point (0, 4).
To summarize, the slope (m) of the line y = (1/5)x + 4 is 1/5, indicating an upward slope, and the y-intercept (b) is 4, representing the point where the line crosses the y-axis.

Max is going to borrow money to buy a TV. For one TV he must pay back $438 in 12 months. For the other TV, he must pay back $555 in 15 months. Which TV has lower monthly payments? Explain how you know
Step-by-step explanation:
"Max is going to borrow money to buy a TV. For one TV he must pay back $438 in 12 months. For the other TV, he must pay back $555 in 15 months. Which TV has lower monthly payments? Explain how you know"
let us solve for the monthly payment expected in both cases
given data
amount= $438
time =12 months
monthly pay = 438/12
monthly pay = $36.5 per month
given data
amount= $555
time =15 months
monthly pay = 555/15
monthly pay = $37 per month
Therefore the First plan which is $438 in 12 months has lower monthly payments because Max will pay $36.5 monthly, the second plan is $0.5 more which is $37

Paul is p years old and Susan, s, is five more than two times Paul's age. Which
equation best represents Susan's age?
A S = (5 + 2)p
Bp = 25 + 5
C S = 2p + 5
D p = (5 + 2)s
Net
Answer:
C - S= 2p + 5
Step-by-step explanation:
So this is what we have:
Paul's age : p
Susan's age: s
S is 5 more than two timess of Paul's age meaning that her age is 5 plus 2 of Paul's age thus:
Susan's age = 2p + 5

A complex number z_1z 1 z, start subscript, 1, end subscript has a magnitude |z_1|=7∣z 1 ∣=7vertical bar, z, start subscript, 1, end subscript, vertical bar, equals, 7 and an angle \theta_1=270^{\circ}θ 1 =270 theta, start subscript, 1, en subscript, equals, 270, degrees. Express z_1z 1 z, start subscript, 1, end subscript in rectangular form, as z_1=a+biz 1 =a+biz, start subscript, 1, end subscript, equals, a, plus, b, i.
Answer:
z1 = 0+7i.
Step-by-step explanation:
Given the complex number
|z1| = 7 and θ1 = 270°
We are to express z1 in rectangular form as;
z1 = a + bi
|z1| = √a²+b² = 7
a²+b² = 7²
a²+b² = 49
.also argument θ1 = tan^-1(b/a) = 270°
Apply tan to both sides
tan(tan^-1(b/a)) = tan270°
b/a = tan270°
b/a = ∞
Since b/a doesn't exist, this means that the denominator is zero i.e a = 0
Substitute a = 0 into a²+b² = 49 to get b as shown;
0²+b² = 49
b² = 49
b = ±√49
b = ±7
Substitute a= 0 and b = ±7 into the rectangular form of the complex number.
z1 = a+bi
z1 = 0+7i
Hence the value of z1 in its rectangular form is z1 = 0+7i.
Answer:
z = 5.785 + 6.894i

A man is three times as old as his son.In ten years time their combined ages will be 68 How old is each person
Answer:
22
Step-by-step explanation:
is 22 because 3 times 22 ut maie us 68
Answer:
Let Dad = Y, Son = X
Mathematically, from your statement:
Y = 3X, and (Y+10) + (X+10) = 68
Solving for X in 2nd equation, X = 48-Y
Insert this into first equation and solve for Y:
Y = 3(48-Y)
Y= 144 - 3Y
4Y = 144
Y = 36
Now, solve for X using either equation. I rearranged the 1st equation for X:
X = Y/3
X = 36/3 = 12
The boy is 12 and the dad is 36
