Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 19.87 minutes of initial set-up time. How long does it take to screen-print a batch of 143 shirts? Write and solve an equation to find the answer.
Answers
Answer:
So the equation and solution will be:
Total time taken = 3 × number of shirts + 19.87 min (setup time)
= 3 × 143 + 19.87
[tex]=429+19.87[/tex]
[tex]=448.87[/tex]
Step-by-step explanation:
From the question statement, it is clear that
screen-printing a batch of shirts requires 3 minutes per shirt in addition to 19.87 minutes of initial set-up time.we have to determine how long does it take to screen-print a batch of 143 shirts.
so the equation and solution will be:
Total time taken = 3 × number of shirts + 19.87 min (setup time)

If the spinner lands on green 10 times out of 60 spins, which statement is true?
The spinner lands on green 5 more times than expected.
The spinner lands on green 5 less times than expected.
The spinner lands on green 2 more times than expected
The spinner lands on green 2 less times than expected.
Answers
Answer: The spinner lands on green 5 less times than expected.
Step-by-step explanation:
Assuming the spinner has 4 colors, the chance of it landing on green will be 25%.
If there are 60 spins, the expected number of times it should land on green is;
= 60 * 25%
= 15 times
It only landed on green 10 times which is 5 less times than expected.

Julietta and Jackson are playing miniature golf. Julietta's ball rolls into a long. straight upward incline with a speed of 2.95 m/s and accelerates at -0.876 m/s/s for 1.54 seconds until it reaches the top of the incline and then continues along an elevated section. Determine the length of the incline.
Answers
Answer:
3.504 m
Step-by-step explanation:
Given that:
The speed (u)= 2.95 m/s
The acceleration = -0.876 m/s²
TIme t = 1.54 s
The length of the incline can be estimated by determining the distance traveled which can be achieved by using the second equation of motion.
[tex]S = ut + \dfrac{1}{2}at^2[/tex]
[tex]S = 2.95 (1.54) + \dfrac{1}{2}(-0.876) (1.54)^2[/tex]
S = 4.543 - 1.039
S = 3.504 m
Thus, the length of the incline = 3.504 m

Is the point (-2,5) a solution for the equation y = 10 + 4x. Explain why and ensure that math
evidence is in your response.
Answers
Answer:
No, the point (-2, 5) is not a solution.
Step-by-step explanation:
To see if the point is a solution, plug the given values for x and y into the equation:
y = 10 + 4x
5 = 10 + 4(-2)
5 = 10 - 8
5 [tex]\neq[/tex] 2
Because the two sides aren't equal to each, the point (-2, 5) can't be a solution.

f–1(x) has a restricted domain.
f–1(x) has a y-intercept of (0, –36).
f–1(x) has an x-intercept of (–36, 0).
f–1(x) has a range of all real numbers.
Answers
Answer:
c and e
Step-by-step explanation:
The conclusions about f⁻¹(x) are ; f⁻¹(x) has a y-intercept of (0, -36) and (e); f⁻¹(x) has a range of all real numbers.
How to determine the conclusions?The function is given f(x) = -2/3x - 24
Express f(x) as y;
y = -2/3x - 24
x = -2/3y - 24
Add 24 to both sides;
x + 24 = -2/3y
Make y the subject,
y = -3/2x - 36
Rewrite
f⁻¹(x) = -3/2x - 36
A linear equation is represented y = mx + b
Where, m represents the slope and b represents the y-intercept
This means :
Slope = -3/2
Y-intercept = -36 or (0,-36)

Brian bought two shirts for $14.50 each and a pair for shoes for $29.99.the sales tax was 6%.how much did Brian spend?
Answers
Answer:
Brian spent 62.5294 $.
Step-by-step explanation:
The cost of two shirts = [tex]2\times \:14.5=29[/tex] $
The cost of 1 pair of shoes = [tex]1\times 29.99\:[/tex] = [tex]29.99[/tex] $
Adding the calculated costs = [tex]29+29.99=58.99[/tex] $Tax calculation:
[tex]\frac{6}{100}\times \:58.99=3.5394[/tex] $Now, adding calculated costs and tax calculation:
58.99$ + 3.5394$ = 62.5294 $
Therefore, Brian spent 62.5294 $.

What is graph of a function?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The graph of a function f is the set of all points in the plane of the form (x, f(x)).
For the given situation,
A local business can be modeled as function q(x) = [tex]x^2 - 4x + 4[/tex]
x is the price of the item in dollars and
q(x) is the number of items produced at that price.
The graph below shows the function q(x).
From the graph, there are zero items produced at a price of $2, because the x-intercept is at (2, 0).
The number of items produced decreases when the price increases from 0 to 2 dollars.
Hence we can conclude that the answers that complete the statements are a) zero, b) x - intercept, c) 0 to 2 are the correct statements.

A train covers 165 km in 1.5 hours. Find the constant variation.
Answers
Answer:
Step-by-step explanation:
110
The required value of constant variation would be 110.
What is the distance?Distance is defined as the product of speed and time.
Direct variation equation can be written as:
y = kx where "k" is a constant variation.
Here y represents the distance covered by the train, and x represents the time duration.
As per the given question,
Since the train covers 165 km in 1.5 hours.
Substitute the values of y = 165 and x = 1.5 in the direct variation equation and solve for k:
⇒ 165 = 1.5k
⇒ k = 165/1.5
Apply the division operation, and we get
⇒ k = 110
Therefore, the required value of constant variation would be 110.

No, he needed to multiply 3 and –1 instead of creating a positive exponent in a fraction. No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Answers
Answer:
No, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
Step-by-step explanation:
The expression is not well written. The expression is written as;
(xy^-2)/(3x²y^-4)
According to indices;
a^m ÷ a^n = a^{m-n}
Applying this to solve the question
1/3(x^{1-2})/(y^-2÷y^-4)
= 1/3(x^{-1})(y^{-2+4})
= 1/3(1/x)y²
= 1/(3x) × y²
Substituting x = 3 and y = -4
= 1/3(1/3)×(-4)²

= 16/9
Imothy solution is incorrect.
According to Imothy solution, his value of (negative 4) squared should be positive because an even exponent indicates a positive value.
