A sports apparel company surveyed the market about the size of T-shirts people most frequently buy, small, medium, large, or extra-large. The
table shows the survey results.
T-Shirt Size Number of responses
small
11
mediurn
37
large
83
extra-large
19
To help Its sales, the company should focus on producing size
T-shirts. Approximately % of T-shirts the company
makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000,
of these will likely be size small.
Answer:
To help Its sales, the company should focus on producing Large
T-shirts. Approximately 80% of T-shirts the company
makes should be medium and large T-shirts to match the market preference. If the total number of T-shirts sold in a month is 45,000, 3,300
of these will likely be size small.
Step-by-step explanation:
In the survey, Large t-shirts are most frequently bought so they should be the primary focus if the company is trying to make more money.
To find the percentage of shirts that the medium and large shirts make up, first you find the total amount of shirts (11+37+83+19=150), then you will find how many mediuma and large shirts (37+83=120). Percentage is (120/150)*100=80%
To find the number of small shirts you can set up a proportion.
[tex]\frac{11}{150} =\frac{x}{45,000}[/tex], then cross multiply
150x=11*45,000
150x=495,000
x=3,300

an angle measure 23 degrees more than the measure of its complementary angle . what is the measure
Answer:
67 degrees or 113 degrees.
Step-by-step explanation:
The other angle is 67 degrees because a complementary angle adds up to 90 degrees. It could also be 113 because that is 23 degrees more than a complementary angle.

On the coordinate plane shown below, points G and I have coordinates (6,4) and (3,2), respectively.
1. Design a strategy in which the Pythagorean theorem is used to calculate the straight line distance between points G and I on a coordinate plane. Use complete sentences to describe the strategy.
2. Use the Pythagorean theorem to determine the distance between the two points on the coordinate plane. In your final answer, include all of your calculations.
3. Use the distance formula and the coordinates of points G and I to prove that the Pythagorean theorem is an alternative method for calculating the distance between points on a coordinate plane. In your final answer, include all of your calculations.
Answer:
points G and I have coordinates (6,4) and (3,2)
Use Pythagorean theorem to calculate the straight line distance between points G and I
points G and I have coordinates (6,4) and (3,2)
Draw a line parallel to y axis passing through G
Draw a line parallel to x axis passing through I
Intersection point K ( 6 , 2)
IK = 6 - 3 = 3
GK = 4 -2 = 2
ΔIKG right angled triangle
Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.
GI² = IK² + GK²
=> GI² = 3² + 2²
=> GI² = 13
=> GI = √13
using distance formula
G (6,4) and I (3,2)
= √(6 - 3)² + (4 - 2)²
= √3² + 2²
= √9 + 4
= √13
Step-by-step explanation:
Answer:
Step-Answer:Given : points G and I have coordinates (6,4) and (3,2)
To Find : Use Pythagorean theorem to calculate the straight line distance between points G and I
Solution:
points G and I have coordinates (6,4) and (3,2)
Draw a line parallel to y axis passing through G
Draw a line parallel to x axis passing through I
Intersection point K ( 6 , 2)
IK = 6 - 3 = 3
GK = 4 -2 = 2
ΔIKG right angled triangle
Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.
GI² = IK² + GK²
=> GI² = 3² + 2²
=> GI² = 13

A circular garden has a circumference of 138 yards. Lars is digging a straight line along a diameter of the garden at a rate of 11 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for π and round the diameter to the nearest whole number, if necessary
Answer:
4 hoursStep-by-step explanation:
Circumference formula:
C = πdUse the given value and find the diameter:
138 = 3.14dr = 138/3.14r = 43.94 ≈ 44 yardsTime required to dig across the garden:

When given a system of equations in slope-intercept form, is graphing or substitution the most efficient method to solve? Explain.
Choose the best answer below.
A.
Substitution is the only method that should be used if the answer involves integer values. If the answer involves values that are not integers, graphing would be more efficient because an exact answer can be obtained. It is easier to read graphs when the point of intersection does not occur at integer values.
B.
Graphing is the only method that would be appropriate to use here because it is not possible to use the substitution method if both equations are in slope-intercept form.
C.
Substitution is the only method that would be appropriate to use here because it is not possible to use the graphing method if both equations are in slope-intercept form.
D.
Graphing and substitution are appropriate to use if the answer involves integer values. If the answer involves values that are not integers, substitution would be more efficient because an exact answer can be obtained. It can be difficult to read graphs if the intersection point does not have integer values so this would be an inefficient method to solve with.

D. Graphing and substitution are appropriate to use if the answer involves integer values. If the answer involves values that are not integers, the substitution would be more efficient because an exact answer can be obtained. It can be difficult to read graphs if the intersection point does not have integer values so this would be an inefficient method to solve with.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, a system of equations in slope-intercept form y₁ = m₁x₁ + b₁ and
y₂ = m₂x₂ + b₂.
We can use both substitution and graphing depending on the numerical values of the variables.
If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.
