Find the length of AB
Answer:
B. 25.2Step-by-step explanation:
AB = AC - BCAC/50 = tan(18° + 28°)AC = 50 tan 46° ≈ 51.8BC/50 = tan 28°BC = 50 tan 28° ≈ 26.6AB = 51.8 - 26.6 = 25.2Answer:
B 25.2
Step-by-step explanation:
AB = AC - BC
= 51.8 - 26.6 = 25.2

The sum of three numbers which are in tne ratio 2:5:7 is 28
Then the smallest number is --
Answer:
4
Step-by-step explanation:
Let the numbers be 2x,5x and 7x respectively.
2x+5x+7x=28
14x=28
x=28/14=2
Therefore the numbers are 2(2)=4,5(2)=10 and 7(2)=14
The smallest number is 4
What is the measure of the circumscribed angle?
Answer:
30°
Step-by-step explanation:
The circumscribed angle is half the difference of the intercepted arcs
arc ELD = 360° - 150° = 210° , then
angle = [tex]\frac{1}{2}[/tex] (210 - 150)° = 0.5 × 60° = 30°
Answer:
30

A typical hour of prime-time television shows
three to five violent acts. Linking family
interviews and police records shows a clear
association between time spent watching TV as a
child and later aggressive behavior. This is an

B. A Controlled Experiment
C. A Survey
Answer:
I think it is A. An Observational Study
Step-by-step explanation:
I think it is this because if you are watching something with interviews and stuff like that, it seems like it would be an observation. If I'm wrong, I am SOOOO sorry this just feels like the right answer.
Determine whether a triangle with the given vertices is a scalene, isosceles, or equilateral triangle. Check all that apply.
9514 1404 393
Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.
_____
Additional comment
It is impossible to specify an equilateral triangle using rational coordinates.

Find the AROC for 6x-9 for the interval x=0 to x=2
Answer:
AROC =6
Step-by-step explanation:
Let f(x)=6x-9
When x=2
f(2) =6(2)-9 = 3
When x=0
f(0)=6(0)-9 =-9
So, average rate of change AROC=[tex]\frac{3-(-9)}{2-0} =\frac{12}{2}[/tex] =6
So, AROC=6

PLEASE HELP ME I AM BEING TIMED, I WILL MARK BRAINLIEST TO WHOEVER GETS THIS RIGHT
Answer:
2.5 min
Step-by-step explanation:
We can start with the fact that [tex]d = st[/tex], where d is the distance traveled at a speed of s for some amount of time t. If we want to solve for t, we can divide both sides of the equation by s to get the form [tex]t=d/s[/tex]. Plugging in the values of d = 12.5 m and s = 5 m/min gives us [tex]t=12.5/5=2.5[/tex] min.

The mean number of minutes spent on a
treadmill at the local gym is 28 minutes with a
standard deviation of 8. If Kurt's z-score is
1.75, how much time did he spent on the
treadmill?
Answer:
With a z score of 1.75, mean of 28 and standard deviation of 8
1.75=(Xi-28)/8
14=(Xi-28)
42 = Xi
Kurt was on the treadmill for 42 minutes
Step-by-step explanation:
what is this equal to
[tex] \frac{a + 8}{2} = \frac{a - 4}{8} [/tex]
