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.

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
This high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards
What is the area of one of the semicircles at either end
The school decided to cover the semicircles with grass to create a space for stretching and other activities. How many square yards of grass will the school need to cover the entire circle
What is the distance around one of the semicircles at either end of the soccer field
What is the distance around the inner lane of the track the lane closest to the soccer field
PLEASE HELP!

Answer:
Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.
The school decided to cover the semicircles with grass to create a space for stretching and other activities.
To Find: area of one of the semicircles at either end of the track
How many square yards of grass will the school need to cover the entire circle?
Solution:
Diameter of semicircle = 70 yards
Radius of semicircle = 70/2 = 35 yards
Area of semicircle at one end = (1/2)πr²
= (1/2)(22/7)35²
= 1,925 sq yards
area of one of the semicircles at either end of the track = 1,925 sq yards
square yards of grass will the school need to cover the entire circle
= 2 x 1,925
= 3850 sq yards
distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards
distance around the inner lane of the track = 100 + 100 + 110 + 110
= 420 yards

This pattern follows the rule divide by 3, then add 7. What are the next two numbers?
294, 105, 42, ________, ________
Question 8 options:
14, 7
21, 14
38, 34
49, 56
Answer:
21, 14
Step-by-step explanation:
by dividing 3 from 42 you get 14, and by adding 7 you get 21. And finally by devifing 3 from 21 you get 7 and by adding 7 to 7 you get 14.

If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?
Answer:
120/100 a = 80/100 b
12/10 a = 8/10 b
10 (12/10) a = 10 (8/10) b
12a= 8b
3a= 2b
a+b in terms of a
b = 3/2×a
a+ 3/2×a = 5/2×a
a+b in terms of b
a = 2/3×b
b + 2/3.b = 5/3×b

distance can't be negative so its 99
Which equation is a function of x?
x = 5
x = y squared + 9
x squared = y
x squared = y squared + 16
Answer:
x squared = y
Step-by-step explanation:
FunctionsThings can get more complicated, but based on the examples given, for an equation to be a function of x, it must have a single y, where the y is not raised to a power.
Option 1: x=5
This equation doesn't have a y, so it isn't a function of x.
Option 2: x = y squared + 9
This equation has y raised to a power, so it isn't a function of x
Option 3: x squared = y
This equation has a y, and the y isn't raised to a power. This is a function of x.
Option 4: x squared = y squared + 16
This equation has y raised to a power, so it isn't a function of x
Determining functions graphicallyIf the equations are graphed, the graphs must pass a vertical line test (a vertical line drawn anywhere should not intersect the graph more than once).
Option 1: x=5
x=5 represents a vertical line, so it fails the vertical line test (the vertical line would overlap and intersect it infinitely many times).
Option 2: x = y squared + 9
x = y squared + 9 is a sideways parabola. A vertical line will cross it twice in several places
Option 3: x squared = y
x squared = y is a parabola that opens upward. It will pass the vertical line test
Option 4: x squared = y squared + 16
x squared = y squared + 16 is a hyperbola (fancy graph shape) that won't pass the vertical line test.
