Answer:
15 m
explanation:
Let AB and CD be the pole and tower respectively. Let CD=h Then ∠DAC=60 ∘ and∠DBE=30 ∘ Now CA CD =tan60 ∘ = 3 ∴CD= 3 CA⇒ 3 h =CA Again BE DE =tan30 ∘ = 3 h ∴(h−10)= 3 BE = 3 CA ...[∵BE=CA] = 3 h/ 3 = 3 h ⇒3h−30=h⇒2h=30⇒h=15
Hence, height of the power =15 m

If I got a 60 on a test , and I have a 92 in that class , what will my grade be ? (please answer i am stressing so much I might get gray hairs)
Answer:
There's no way to answer this question 100% accurately, because we don't know your teacher's grading scale, or how much tests and quizzes are weighted for your grade in the class. That being said, one test shouldn't bring your grade down too much. As the year goes on, and more assignments are put in the gradebook, it will even out. If you get a 100 percent on 3 tests, and a 60 percent on one test, it evens out to a 90 percent.
If you need more help, type in "Rogerhub grade calculator." It's a website that is very helpful in calculating your grade for the year. Hope this helps! :)
I forgot how to divide fractions properly. please send help.
Answer:
2.5 or 10/4
Step-by-step explanation:
2÷4/5
Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,
2/1÷4/5
But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)
2/1×5/4
And tadaa! you get your answer
10/4

write the equation of the line parallel to 2x - 3y = 0 and passes through the point (5, 4).
Answer:
2x - 3y = 2Step-by-step explanation:
Parallel lines have same slope
Given line, in slope intercept form
2x - 3y = 03y = 2xy = 2/3xParallel line is
y = 2/3x + bUsing point (5, 4) to find b
4 = 2/3*5 + bb = 12/3 - 10/3b = 2/3y = 2/3x + 2/3 in slope-intercept form or
2x - 3y = 2 in standard form

A music store is receiving a shipment of Ipads. Each box comes with 12 white, 12 black and 24 grey
Ipads. They already have 23 white, 16 black and 22 grey Ipads. If the store is receiving 5 boxes, how
many of each color Ipad will they have?
Answer:
142 Grey, 83 white, 76 black
Step-by-step explanation:
If you were to take 5 boxes and put 24,12,12 in each, then multiply each number by 5 you wpuld get 120 Grey, 60 white and 76 black. Then you would add what they already have 120 Grey + 22 Grey is 142 grey, 60 white + 23 white is 83 white, and 60 black + 16 black is 76 black.
Two shelters offers dog adoption twice a year ruff had 123 dogs adoption in january 196 fogs adoption in July barks had 78 dogs adoption in January and 135 adoption in July estimates the difference in the number of dogs adoption at each shelter that year
Answer:
106
Step-by-step explanation:
ruff
123 dogs adoption in january
196 dogs adoption in July
Total adoption for the year = 123 + 196
= 319 adoptions
barks
78 dogs adoption in January
135 adoption in July
Total s like adoption for the year = 78 + 135
= 213 adoptions
Difference in the number of dogs adoption at each shelter that year
= Ruff total adoption for the year - Bark's total adoption for the year
= 319 adoptions - 213 adoptions
= 106
The difference in the number of dogs adoption at each shelter that year is 106

Rachel and four friends were going to the movies. Each ticket cost $11 and then they bought 2 popcorns at $3.75 each, and they each bought their own soda at $2.75 each. How much money did they spend total for their trip to the movies? If they decide to split the bill, how much will they each pay?
Answer:
Total amount spent [tex]=\$73.5[/tex]
If they decide to split the bill, amount paid by each of the person [tex]=\$15.25[/tex]
Step-by-step explanation:
Cost of each movie ticket = $11
Cost of 5 tickets = 5(11)= 55
Cost of each packet of popcorns = $3.75
Cost of two packets of popcorns = $2(3.75) = $7.5
Cost of each soda = $2.75
Cost of five sodas = $5(2.75) = $13.75
Total number of persons (Rachel and four friends) = 5
Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]
If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]

PLEASE HELP HELP. I don’t get the 8 and 9
Answer: y=8 m=5
Step-by-step explanation:
Answer:
1. 3.125
2. 4.5
Step-by-step explanation:
1. Since the figures are similar, the number you divide from one triangle to the other is the same, no matter the side length. 5(x) = 8 so 5/x = y. If x = 1.6, then y equals 3.125.
2. The same thing here. 4/x = 3 and 6/x = m. In the first equation x would be 1 1 1/3. 6/ 1 1/3 is the same as 6 x 3/4 which is 18/4 or 4.5.

The distance between two points (-9,2) and (5,-4) is 15.23 units.
What is the distance between two points?The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.
The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².
We have to determine the distance between (-9,2) and (5,-4)
As per the question, substitute the known values in the formula,
d = √ {(-9 – 5)² + (2 – (-4))²}
d = √ {(-14)² + (6)²}
d = √ {196 + 36}
d = √232
d ≈ 15.23
Thus, the distance between the given two points is 15.23 units.

Given:
After driving for 20 minutes, Juan was 62 miles away from his apartment.
After driving for 32 minutes Juan was only 38 miles away.
The time driving and the distance away from his apartment form a linear relationship.
To find:
The independent and dependent variables.
Solution:
If the value of a variable depends on the another, then it is called dependent variables.
If the value of a variable does not depend on the another, then it is called independent variables.
In the given problem, the distance of Juan from his apartment depends on the time he drove. So,
Dependent variable = Distance of Juan from his apartment in miles.
Independent variable = Time he drove

The range of a relation is
A. the output (y) values of the relation
B. the input (x) values of the relation
C. a set of points that pair input values with output values
D. x and y values written in the form (x, y)
A.
Step-by-step explanation:
Range of a function is the value that we get when a function is solved.
Say, f(x) = y.
We say this "set of x is domain" whereas "set of y is range".
Suppose,
set A = {1,2} & set B = {1,2,3} & f(x) = y
Let,
f(1) = 1, & f(2) = 2.
What we get is that there is no x for 3.
We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.

You can find this by using the pythagorean theorem.
The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.
The hypotenuse is the longest side, which is opposite the right angle.
The other 2 sides are the legs.
Here, the hypotenuse is BC which is 17.
AC is one leg. We are trying to find the other leg.
So you set up the equation AB^2+ 15^2 = 17^2.
This simplifies to AB^2 + 225 = 289.
AB^2 = 64.
AB = 8.
