Colton works at an electronics store as a salesperson. Colton earns a 7% commission on the total dollar amount of all phone sales he makes, and earns a 3% commission on all computer sales. Colton had twice as much in phone sales as he had in computer sales and earned a total of $85 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Colton made and the dollar amount of computer sales he made. Define the variables that you use to write the system.
The equations that could be used to determine the dollar amount of phone sales will be:
0.07x + 0.03y = 85
y = 2x
How to illustrate the information?Let x represent the total dollar amount of the phone sales she makes.
Let y represent the total dollar amount of the computer sales she makes.
Colton earns a 10% commission on the total dollar amount of all phone sales she makes, and earns a 4% commission on all computer sales. If she earned a total of $162 in commission, it means that
0.07x + 0.03y = 85
She had twice as much in computer sales as she had in phone sales. This means that y = 2x.

When catering an event, Bennett's Barbeque charges a flat $200 setup fee plus $14 per person.
The cost of the annual picnic for Gambles Construction must be under their $3000 budget.
Write an inequality that determines the total number of people, "x," that can attend the picnic.
If needed, use > for "greater than"
If needed, use < for "less than"
Step-by-step explanation:
so, to translate the first 2 paragraphs into math notation :
200 + 14×x < 3000
that transforms then to
14x < 2800
and then
x < 2800/14 = 200
so, x < 200
the number of attending people must be under 200.
therefore up to 199 people can attend.
FYI : the request was that the costs must be under the $3000 budget. therefore, we used "<".
if we were allowed to actually reach (and empty) the full budget, then we would have used "<=" (less than our equal), and 200 people could attend.

Bernice estimated that 69% of 242 is 168. Is her estimate reasonable?
No, because her calculation should be 60% of 250.
No, because her calculation should be 70% of 250.
Yes, because her calculation should be 60% of 240.
Yes, because her calculation should be 70% of 240.
Answer:
Yes, because her calculation should be 70% of 240.
Step-by-step explanation:
69% can be estimated to 70% and
242 can be rounded off to 240.
70% of 240 = 0.7 * 240
= 168

The co-ordinates of D is if the midpoint E is at (-1,0 )which is calculated using the section formula.
In coordinate geometry, the Section formula is used to determine the internal or external ratio at which a line segment is divided by a point. It is used to determine a triangle's centroid, incenter, and excentre.
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The section formula is given by:
[tex]{\displaystyle P=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
The midpoint is calculated by:
[tex]{\displaystyle Q=\left({\dfrac {x_{1}+x_{2}}{2}},{\dfrac {y_{1}+y_{2}}{2}}\right)}[/tex]
where (x₁ ,y₁) and (x₂ ,y₂) are the two endpoints of the line -segment.
Now the given co-ordinates of the points are C(5, 2) and the midpoint is E(-1 , 0). Now to find the co-ordinates of D we have to use the midpoint formula.
Let the co-ordinate's of D be (a , b) then by using the above midpoint formula we get:
-1 = (5+a) ÷ 2
or, a = -2 -5
or, a = -7
again
0 = (2+b) ÷ 2
or, b = -2
Hence the co-ordinates of D is (-7 , -2)

A. 594 cm2
B. 33.0 cm2
C
C. 16.5 cm2
D. 297 cm2

Answer:
297 cm^2
Step-by-step explanation:
297 centimeters squared
The requried area of the shaded sector is 296.73 cm², which is closest to option D: 297 cm².
What is an area of a sector of a circle?The area of a sector is the fractional part of the area of a full circle that is enclosed by the central angle of the sector. To find the area of a sector, we can use the formula:
Area of sector = (θ/360) x πr^2
Here,
To find the area of the shaded sector, we need to first find the area of the whole circle and then multiply it by the fraction of the circle that is shaded.
The area of a circle with a radius of 18 cm is given by A = πr², where r is the radius. So, the area of the whole circle is:
A = πr² = π(18 cm)² = 324π cm²
To find the fraction of the circle that is shaded, we need to find the central angle of the sector. The central angle of the sector is given as 105°. The fraction of the circle that is shaded is equal to the central angle of the sector divided by the total central angle of the circle (which is 360°):
Fraction of circle shaded = Central angle of sector / Total central angle of a circle
= 105° / 360°
= 7/24
Therefore, the area of the shaded sector is:
Area of shaded sector = Fraction of circle shaded x Area of the whole circle
= (7/24) x (324π cm²)
≈ 296.73 cm²
So, the approximate area of the shaded sector is 296.73 cm², which is closest to option D: 297 cm².

The sum of two numbers is 96 the larger number is nine less than four times the smaller number find both numbers
Answer:
21 and 96
Step-by-step explanation:
Let x and y be the two numbers such that x>y.
As the sum of both the numbers is 96.
x+y=96...(i)
As the larger number is nine less than four times the smaller number,
So, x=4y-9
From equation (i),
4y-9+y=96
5y=96+9=105
So, y=105/5=21
By using equation (i),
x=96-y=96-21=75
Hence, both the numbers are 21 and 96.
at sue birdwell intermediate school the ratio of boys to girls is 7 to 5. if there are 150 girls at school, how many boys are at the school
Answer:
210 boys
Step-by-step explanation:
the ratio is 7 boys to 5 girls. There are 150 girls at the school. Divide 150 by 5 to get your answer which is 30. We know that we have to divide because the ratio answer is a simplified version of 150, like if we were doing fractions. Then multiply 30 times 7 and you will get 210. So there are 210 boys at the school.

Find the circumference of the circle use 3.14 for
Pi Round to the nearest hundred put the answer in cm
Need ASAP if u don’t know the answer don’t answer
Answer:
47.1 cm
Step-by-step explanation:
The circumference of a circle is denoted by C = 2πr, where r is the radius.
Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:
C = 2πr
C = 2 * 3.14 * 7.5 = 47.1
To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.
Thus, the circumference is 47.1 cm.

Assuming all parabolas are of the form y=ax^2+bx+c, drag and drop the graphs to match the appropriate a-value
9514 1404 393
Answer:
graphs left to right have a=1, a=0.25, a=-1
Step-by-step explanation:
A negative value of 'a' makes the parabola open downward, so the rightmost graph goes with a=-1.
A value of 'a' less than 1 flattens the graph, so the middle graph goes with a=0.25.
A value of 1 gives a standard open-upward parabola, corresponding to the leftmost graph.
