Answer: The cost of each baseball cap = $15.
Step-by-step explanation:
Let x = cost of each baseball cap
Given; cost of each baseball jersey= $45
Total coast of 3 baseball caps and 1 baseball jersey = $90
i.e. [tex]3x+45=90[/tex]
[tex]\Rightarrow\ 3x=45\\\\\Rightarrow\ x=\dfrac{45}{3}\\\\\Rightarrow\ x= 15[/tex]
Hence, the cost of each baseball cap = $15.

Find the equation of the vertical line that passes (-2,-9)
Answer:
x = -2
Step-by-step explanation:
That's really it, since it's a vertical line.
Answer:
The equation of vertical line, parallel to y-axis is
x + k=0
Here, the line passes through the point (–2,–9)
So, –2 + k = 0
=> k = 2
The required equation be, x + 2 = 0
Sofia still lives at home, but helps with the rent paying $200 per month. She has a job that pays about $700 per month after taxes. She has to pay for her own personal items such as clothing and toiletries spending about $120 per month. Going out with friends is important to her, but she also wants to save money to buy her own car. Select the budget that would best help meet her goals.

Answer:
Budget A
Step-by-step explanation:
Total monthly budget is;
T = Rent cost + Personal Items cost + Entertainment cost +Savings cost
For budget A;
T_A = $200 + $120 + $100 + $250
T_A = $670
For budget B:
T_B = $200 + $120 + $300 + $50 = $670
Foe budget C;
T_C = $200 + $120 + $200 + $150
T_C = $670
For budget D;
T_D = $200 + $120 + $325 + $25 = $670
We can see the total budget for all is $670.
Her rent and personal expenses have fixed amounts. Thus, the only ones that can vary are Entertainment cost and Savings cost.
Now, in all the budgets, budget A has the highest savings which is $250.
Thus, we can say it's the best budget to help her meet her goals as it still provides $100 for even entertainment which she loves with her friends.
Answer:
budget A

Step-by-step explanation:
An archway in front of a school is in the shape of a parabola. The top of the arch is the vertex (0,0). The school seal is at the focus, 2.5 feet below the vertex, and the arch is 18 feet wide at the ground
Answer:
a) The equation of the arch is [tex]y = -10\cdot x^{2}[/tex].
b) The height of the arch from the ground is 810 feet.
Step-by-step explanation:
Statement is incomplete. Complete statement is:
An archway in front of a school is in the shape of a parabola. The top of the arch is the vertex (0,0). The school seal is at the focus, 2.5 feet below the vertex, and the arch is 18 feet wide at the ground.
Write an equation that represents the arch.
What is the height from the top of the arch to the ground?
a) Write an equation that represents the arch.
According to the statement, the archway is a vertical downward parabola. From Analytical Geometry we know that parabolas are represented by the following equation in standard form:
[tex]y-k = 4\cdot p\cdot (x-h)^{2}[/tex] (Eq. 1)
Where:
[tex]p[/tex] - Distance between vertex and focus, measured in feet.
[tex]x[/tex] - Independent variable, measured in feet.
[tex]y[/tex] - Dependent variable, measured in feet.
[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, measured in feet.
If we know that [tex]p = -2.5\,ft[/tex], [tex]h = 0\,ft[/tex] and [tex]k = 0\,ft[/tex], then the equation that represents the arch:
[tex]y = -10\cdot x^{2}[/tex]
The equation of the arch is [tex]y = -10\cdot x^{2}[/tex].
b) What is the height from the top of the arch to the ground?
Given that parabola is a symmetrical curve, we determine the vertical position at the base of the arch ([tex]x = 9\,ft[/tex]):
[tex]y_{min} = -10\cdot (9\,ft)^{2}[/tex]
[tex]y_{min} = -810\,ft[/tex]
Then, the height of the arch from the ground is given by this difference:
[tex]h = 0\,ft-(-810\,ft)[/tex]
[tex]h = 810\,ft[/tex]
The height of the arch from the ground is 810 feet.

The whole number 23 is an example of a prime or composite number.
Step-by-step explanation:
Hey there!
23 is a prime number.
Reason:
Prime number are those numbers which are divisible by 1 and itself.
Example: 5 is divisible by 1 and 5 only. so, it is a prime number.
Composite numbers are those numbers which are divisible by more number.
Example: 6 is divisible by 1,2,3,6 so, it is a composite number as it is divisible by others number expect 1 and itself.
Hope it helps...
23 is an example of a prime number because it has only two factors.

what is the change between -15 and 11
Answer:
26
Step-by-step explanation:
Take the second number and subtract the first number and take the absolute value
| 11 - -15|
|11 +15|
|26|
26
Answer:
26 units apart
Step-by-step explanation:
Since we want the total change/distance, subtract and take the absolute value.
-15 - 11 = -26
|-26| = 26

Felice swims 3 times every 7 days.
How many times will she
swim in 28 days?
Answer:
12 times.
Step-by-step explanation:
If she swims three times a week, then you need to find how many weeks make up 28 days. 28/7= 4 weeks. Since she swims three times a week, you multiple that by the amount of weeks, which is four. You get that she swims 12 times in 28 days.
Complete the pattern.

Jack reads his book for 8 minutes before school and 10 minutes after school. He attends school Monday through Friday. Which equation shows how many minutes Jack reads his book in two weeks? A. (8 × 5) + (10 × 5) = 40 + 50 = 90 minutes B. (8 × 8) + (10 × 10) = 64 + 100 = 164 minutes C. (8 × 10) + (10 × 10) = 80 + 100 = 180 minutes D. (8 × 14) + (10 × 14) = 112 + 140 = 252 minutes
Answer:
(8 × 10) + (10 × 10) = 80 + 100 = 180 minutes
Step-by-step explanation:
It is given that, Jack reads his book for 8 minutes before school and 10 minutes after school.
No of days between Monday to Friday = 5
No of days between Monday to Friday in 2 weeks = 10
We need to find how many minutes Jack reads his book in two weeks.
For 10 days, before school = (8 × 10) min = 80 minutes
For 10 days, after school = (10 × 10) min = 100 minutes
It means, total time will be :
T = (8 × 10) min + (10 × 10) min
T = 80 + 100
T = 180 minutes
Hence, the correct option is (C).

Answer:
[tex]m=-3[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{5-(-1)}{-5-(-3)}[/tex]
[tex]m=\frac{5+1}{-5+3}[/tex]
[tex]m=\frac{6}{-2}[/tex]
[tex]m=-3[/tex]
Audrey has already scored 53 points,and scored 22 more points with every coin she collects.How many coins does Audrey have to collect to score a total of 97 points
Answer:
Audrey needs to collect 3 more coins.
Step-by-step explanation:
Since she already scored 53 points, we have to find out how many more points she needs to score 97.
So, 97-53=45 points.
The problem says that each coin Audrey collects is worth 22 points. Therefore, 45 divided by 22= 2 remainder 1. However, if she only collects two more coins, Audrey will only have 96 points in total, not 97.
So, add another coin to make 3.
