Please help!!!!!
Answer:
12
Step-by-step explanation:
if you draw the picture in your copybook you will see that there is a right triangle, we have the Pythagorean theorem i.e c=√a²+b²
15=√9²+x². the trees tall=X
15²=9²+x²
x²= 144
X= 12

3b. If the profile picture of Mark's sister is 3.5 inches tall, how tall is her actual height?
Her actual height is _____ inches.
70
82
59.5
66.5
Step-by-step explanation:
Answer: 19, because all you´re doing for mark is dividing his actual height from the profile picture.
Marks sister: 66.5, because you will take her height (3.5) and you will put x over 3.5 in fraction form. Then you will take marks profile picture height, and put it in fraction form (76 over 4) then you will cross multiply 3.5 and 76 which will give you 266. Then you´ll divide 266 by 4 which would give you 66.5
a bus travels 320 miles in 6.4 hours. if the bus continues at the same rate, which proportion can be used to find m, the number of miles the bus will travel in 9 hours.
Answer:
A
Step-by-step explanation:
Ok first we need to find rate of MILES per HOUR
320/6.4=50
m= miles in 9 hours
9*50=450
Cross Multiplyis your answer
A
(6.4*9)/320m=Hours/miles
Hope this helps!
The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.
We know that speed is the ratio of distance and time. Then we have
The number of miles the bus will travel in 9 hours will be
320 / 6.4 = m / 9
6.4 / 320 = 9 / m
Then the correct option is B.

3x – 4y = 2; 6x – 8y = 1 .
How many solutions PLEASE
Answer:
No solution
Step-by-step explanation:
3x - 4y = 2
6x - 8y =1
Multiply the first equation by -2 so you can eliminate the x's.
-2(3x-4y =2)
6x - 8y = 1
-6x + 8y = 2
6x - 8y = 1
Add the equations so they cancel.
0 + 0 = 3
0 [tex]\neq[/tex] 3, therefore there are no solutions.

Find the slope of the line that passes through (10, 92) and (97, -3).
Answer:
-95/87
Step-by-step explanation:
Formula to find slope: (y2-y1) / (x2-x1)
In this problem y2 is -3 and y1 is 92. x2 is 97 and x1 is 10.
We substitute these numbers into the equation.
(-3-92) / (97-10)
Then we simplify this by subtracting.
-95/87 is our final answer.

Decide whether there is enough information to prove that a∥b. If so, state the theorem you would use.
Answer: C) Yes, Alternate Exterior Angles Converse
The two red angles are on the outside of the lines a and b, so they are considered exterior. They alternate on either side of the transversal line. So we consider those red angles to be alternate exterior angles. We'll use the alternate exterior angles converse to prove the lines parallel. That converse states: "If alternate exterior angles are congruent, then the lines are parallel".
