The measure of the reference angle for a -287° angle is 17°.
To measure of the reference angle for a -287° angle
1. Determine the quadrant: First, we need to identify the quadrant in which the angle -287° lies.
- In the standard coordinate plane, angles between 0° and 90° are in the first quadrant, between 90° and 180° are in the second quadrant, between 180° and 270° are in the third quadrant, and between 270° and 360° are in the fourth quadrant.
- Since -287° falls in the third quadrant, we know that the reference angle will be found in the first quadrant.
2. Find the corresponding acute angle: To find the reference angle, we need to find the acute angle that has the same trigonometric values as the given angle.
- To do this, we can add 360° to the given angle (-287° + 360° = 73°). This gives us an equivalent positive angle in the same position.
3. Determine the reference angle: Now that we have the positive equivalent angle (73°), we can find the reference angle by subtracting it from 90° (90° - 73° = 17°).
Therefore, the measure of the reference angle for a -287° angle is 17°.

Every seventh-grade student at Martin Middle School takes one world language class.
One-tenth of the seventh-grade students take French. Eighteen seventh-grade students take French.
Which equation represents s, the total number of seventh-grade students at the middle school?
18 = 0.1 s
18 = StartFraction 10 over s EndFraction
StartFraction s over 0.1 EndFraction = 18
10 s = 18
Option (A) 18 = 0.1s
Step-by-step explanation:
Every seventh-grade student at Martin Middle School takes one world language class.
Now we will form the equation as per statement of the question.
Let total students of seventh-grade = s
" one tenth of seventh grade students take French."
" Students who took French were 18."
So of s = 18
(0.1)s = 18
therefore, Option (A) 18 = 0.1s is the answer.

Eli has a collection of football and baseball cards. In all, he has 360 cards in his collection. Twice the number of baseball cards is 30 less than three times the number of football cards. How many more baseball cards than football cards does Eli have?
Answer:
150 football cards
210 baseball cards
Step-by-step explanation:
b + f = 360
2b = 3f - 30
Change second equation to be: 2b - 3f = -30
Multiply first equation by -2 to get: -2b -2f = -720
Add to get: -5f = -750
f = 150
b = 360-150 = 210

A. Any Length
B.Equal to 10
C.Greater than 10
D.Less than 10
Answer:
C.Greater than 10Step-by-step explanation:
It is because of
Triangle Inequality Property rule:
Measurement of any two sides of the triangle is always greater than the third side.
So,
As per the rule the sum of other two shorter sides of the triangle should be greater than 10.
The two shorter sides must have a sum that is greater than 10.
What is a triangle?A triangle is a polygon with three sides and three angles.
Analysis:
For a triangle, the sum of the two shorter sides is usually greater than the longest side.
In conclusion, the sum of the two shorter sides must have a sum greater than 10.

is Hannah being offered?
A. 11.87%
B. 13.00%
C. 12.93%
D. 12.22%
i believe the answer is A.11.87% because interest rates tend to be lower than APR
If the first 30 days and 12.22% APR afterwards, compounded daily. The effective interest rate is: A. 11.87%
Effective interest rateAfter 1 year the daily percentage rate is compounded for:
(365 days - 30 dyas) = 335 days
Hence:
Effective interest rate=(1+0.1222/365)^335-1
Effective interest rate=(1+0.1222/365)^335-1
Effective interest rate=(1+0.00033479)^335-1
Effective interest rate=(1.00033479)^335-1
Effective interest rate=(1.11866-1)
Effective interest rate=0.11866×100
Effective interest rate=11.87% (Approximately)
Therefore the effective interest rate is: A. 11.87%.

Cindy owns a rectangular lot that is 18 yards long and 45 feet wide.
She is going to cover the lot with square pieces of sod. If the sod costs $12 per square yard, how much will Cindy pay to completely cover the lot with sod?
Answer:
$3240
Step-by-step explanation:
First you need to find the area of that lot. Area of a rectangle = length x width. But you also have mixed units...yards and feet. Since the price of the sod is in square yards, we'll convert the 45 feet to yards. 3 feet = 1 yard, so divide 45 by 3, = 15 yards.
18 x 15 = 270 square yards
then you multiply that by the $12/square yard
270 x 12 = $3,240

Answer:
406
Step-by-step explanation:
Given: product of two positive integers us 2005.
Let the two positive integers be a and b
Now prime factorization of 2005 = 401×5
where both 401 and 5 are prime number and non of them is 1.
So, and b will be 401 and 5 respectively.
Therefore, sum of the two integers a+b = 401+5 = 406
