Answer:
m∠L + m∠M = 90°
sin(L) = 0.66913
sin(M) = 0.74314
Step-by-step explanation:
The sum of the two angles is ...
m∠L + m∠M = 42° +48° = 90°
__
A calculator can show you the sines of these angles.
sin(42°) ≈ 0.66913
sin(48°) ≈ 0.74314
_____
The two acute angles of a right triangle always have a sum of 90°.

Answer: B
Step-by-step explanation: Step 1: Subtract 3x from both sides.
4x−5−3x=3x−10−3x
x−5=−10
Step 2: Add 5 to both sides.
x−5+5=−10+5
x=−5
hope this help
Answer:
B. x-5
Step-by-step explanation:
Step 1: Subtract 3x from both sides.

Answer:
3 6/12
Step-by-step explanation:
1 1/3 goes to 1 4/12
2/3 goes to 8/12
3/4 goes to 9/12
3/4 goes to 9/12 (again)
1 4/12 + 8/12= 2
9/12 + 9/12= 1 6/12
1 6/12 + 2 = 3 6/12

Answer:
x = 27°
Step-by-step explanation:
Each exterior angle is equal to the sum of the remote interior angles.
6x = 90° +(180° -4x)
10x = 270° . . . . . add 4x
x = 27° . . . . . . . . divide by 10
_____
Check
6x = 162°, so the adjacent interior angle of the triangle is 180° -162° = 18°.
4x = 108°, so the adjacent interior angle of the triangle is 180° -108° = 72°.
The interior angles of the triangle are complementary, as they should be.
18° +72° = 90°

2x-15y=6
x-6y=-1
Step-by-step explanation:
2x-15y=6---->1
x-6y=-1
x=-1+6y----->2
use substitution
substitute 2 in 1
2(-1+6y)-15y=6
-2+12y-15y=6
-3y=6+2
-3y=8
y=-8/3
x=1+6(-8/3)

Mr. Parker wants to rent a cargo van for a day. It will cost the daily fee of $50.00 plus $0.35 per mile driven.
Let m = the number of miles Mr. Parker drives for the day. Write an algebraic expression that shows the amount he will pay for the van.
Answer:
50d * 0.35m
Step-by-step explanation:
so I don't normally do it like this it would normally be 50 * 0.35x. but the days also had a fee unless she doesn't have it for 2 days and only has it one but d is the days she has it and m is the miles driven the * is times
you would have to find out the days she has it unless you don't have that is would be the answer above (if I am wrong I'm sorry)

A class has 30-40 students. Each boy in the class bring 15 chocolate bars for a class party to celebrate Teacher's Day. The chocolate bars are shared equally among the 20 girls of the class and their form teacher with no leftovers.
(i) How many students are there in the class?
Detailed steps please!
9514 1404 393
Answer:
34
Step-by-step explanation:
In order to divide some multiple of 15 chocolate bars evenly by 21, the number of bars must be a multiple of the LCM of 15 and 21, which is 105. That number is 7 times 15, indicating the number of boys in the class must be a multiple of 7. The only number between 30-20 = 10 and 40-20 = 20 that is a multiple of 7 is 14.
There must be 14 boys in the class, so 34 students in total.
__
The boys brought a total of 210 chocolate bars, so each girl and the teacher received 10 of them.
A dilation with a scale factor of 1/3 is a reduction. A dilation with a scale factor of 2 is a reduction . which is true and which is false
Answer:
True: A dilation with a scale factor of 1/3 is a reduction.
False: A dilation with a scale factor of 2 is a reduction.
Step-by-step explanation:
A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.
On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.
So, the statement that a dilation with a 1/3 scale factor is a reduction is true.
The other statement is false, which says a dilation with a scale factor of 2 is a reduction.
