What is the measure of the angle that the ladder makes with the wall?
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°

Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake. His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet. What is the vertical distance between Dan and Jeff? Please show work.
Answer:
The vertical distance between Dan and Jeff is of 26 feet.
Step-by-step explanation:
Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake.
His position is -34 feet.
His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet.
Dives to 40 feet, and descends 20 more feet. So
-(40 + 20) = -60
What is the vertical distance between Dan and Jeff?
|-34 - (-60)| = |-34 + 60| = 26
The vertical distance between Dan and Jeff is of 26 feet.

Answer:
4 times, he bought dinner 4 times
Step-by-step explanation:
if kevin get paid for 3 hours, then you would multiply $14 by 3. you would end up with $42, then the weekly allowance is $21. then by adding $21 to the $42 we have you would get $63. then a bus ride costs $2.50 and since he rode it 6 times you would multiply $2.50 by 6, which would equal $15. Then subtracting $15 from the $63, you would end up with $48, and then by dividing the total amount for the dinner each time bought, so $12/$48 would equal to 4 times.

Scarlett walks along the edges of a
rectangular path from A to B to C to D, a
distance of 38 metres. Jake walks along the
same rectangle, but from B to C to D to A,
a distance of only 31 metres.
What is the area, in square metres, of rectangle ABCD?
D
С
Answer:
168 meters squared
Step-by-step explanation:
So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.
So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m
38-14=24
so now we know that the side is 24 and we can solve for the area
24*7=168
so the answer is 168 meters squared

48 is 12% of what number?
Answer:
I'm not sure but from my calculations,it is 400
Answer:
400
Step-by-step explanation:
In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.
48÷0.12 or 48/0.12 = 400

A classroom is arranged with 6 seats in the front row, 8 seats in the middle row, and 10 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom.
What is the probability that the first student who enters the classroom will be assigned a seat in the front row?
Answer:
[tex] \frac{6}{24} \: or \: 0.25 \: or 25\%[/tex]
Step-by-step explanation:
First add them all up to get the total amount of seats.
6+10+8=24
there are 6 seats in the front row. so that means it will be
[tex] \frac{6}{24} [/tex]
24÷6=0.25
0.25×100=25%
Probability can be answered with a fraction, decimal or a percentage, they are all correct.

Find the 89th term of the arithmetic sequence 25, 35, 45, ...
Answer:
905
Step-by-step explanation:
arithmetic sequence are in form
a(n)=a(0)+d(n-1)
a(0)=25
common difference: d=35-25=10
a(n)=25+10(n-1)
a(89)=25+10(88)=905
Fred's car can travel 36.8 miles on one tank of gas. His gas tank holds 16 gallons. How many miles can Fred's car travel per gallon?What is the solution of the equation below? x+8.63=11.001
Answer:
Answer to Question 1: 2.3 miles per gallon
Answer to Question 2: x = 2.371
Step-by-step explanation:
Question 1 (explanation): 36.8 (miles on one tank of gas) / 16 (gallons of gas that Fred's car hold) = 2.3 (miles that Fred's car can travel per gallon)
Question 2 (explanation): 11.001 - 8.63 = 2.371
