The length of a side of an equilateral triangle is 40 centimeters.
What is the length of the altitude of the triangle?
Answer:
34.64 cm
Step-by-step explanation:
sin 60 = [tex]\frac{x}{40}[/tex]
sin 60 (40) = x
34.64 = x
equilateral triangles have 60° angles.
sin Ф = [tex]\frac{opposite}{hypotenuse}[/tex]
hypotenuse is 40. All sides are 40.
x = opposite or height of triangle.

Tomaz realized that the tip of a second hand on a clock rotates about the center of the clock. He watched the second hand rotate around the center of the clock for 15 seconds. Which describes the rotation he observed?
270 degrees clockwise rotation
90 degrees clockwise rotation
180 degrees rotation
90 degrees counterclockwise rotation
Answer:
Step-by-step explanation:
Second hand on a clock rotates at rate 360 degrees per 60 seconds.
360 degrees - 60 sec
x degrees - 15 sec
90 clockwise rotation (none hand of a clock rotates counter-clockwise :))
Answer:

Como Determinar a equação da reta que passa pelos pontos A(-1, -2) e B(5,2)
Answer:
A equação da reta é dada por: [tex]y = \frac{2}{3}x - \frac{4}{3}[/tex]
Step-by-step explanation:
Equação de uma reta:
A equação de uma reta tem o seguinte formato:
[tex]y = ax + b[/tex]
Em que a é o coeficiente angular e b é o coeficiente linear.
Coeficiente angular:
Com posse de dois pontos, o coeficiente angular é dado pela mudança em y dividida pela mudança em x.
A(-1, -2) e B(5,2)
Mudança em y: 2 - (-2) = 2 + 2 = 4
Mudança em x: 5 - (-1) = 5 + 1 = 6
Coeficiente angular: [tex]m = \frac{4}{6} = \frac{2}{3}[/tex]
Então:
[tex]y = \frac{2}{3}x + b[/tex]
Coeficiente linear:
Substituindo um ponto na equação, encontra-se o coeficiente linear.
B(5,2)
Quando [tex]x = 5, y = 2[/tex]. Então:
[tex]y = \frac{2}{3}x + b[/tex]
[tex]2 = \frac{2}{3}5 + b[/tex]
[tex]b = 2 - \frac{10}{3} = \frac{6}{3} - \frac{10}{3} = -\frac{4}{3}[/tex]
Então:
[tex]y = \frac{2}{3}x - \frac{4}{3}[/tex]

Use the elimination method to solve the system of equations
2x+3y=8
x-y=9
Answer:
Step-by-step explanation:
Answer: x = 7 and y = -2
Step-by-step explanation:
2x +3y = 8 ----------------(1)
x-y = 9 ----------------------(2)
multiply (2) by 2
2x-2y = 18--------------------(3)
subtract (2) from (3)
-5y = 10
Divide bothside by -5
y = -2
Similarly, multiply (2) by 3
3x-3y = 27-----------------------(4)
add (1) and (4) together
5x = 35
Divide bothside by 5
x= 7
Therefore, x =7 and y= -2
(-6)^-1 multiply by x = 27^-1. find x

Finish solving the system of equations.
x – 5y = 6
–x + 2y = –3
–3y = 3
What is the value of y?
Substitute the value of y back into one of the original equations to find the value of x. What is the value of x?
Answers: x = 1 and y = -1
Explanation:
Start where your teacher left off, which is -3y = 3.
We solve for y by dividing both sides by -3
That turns -3y = 3 into y = -1
Then we use this y value to find x
x - 5y = 6
x - 5(-1) = 6
x + 5 = 6
x = 6-5
x = 1
The solution is (x,y) = (1, -1)
Answer:

A main purpose of doing an experiment over an observational study is to learn whether a certain _____ causes a certain response.
Answer:
condition
Step-by-step explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
On the other hand, an observational study can be defined as a type of study in which a researcher observes and measures the effect of a diagnostic test, risk factors, or treatments on individuals without intervening, changing or manipulating who are or aren't exposed to it (controlled conditions).
Hence, the main purpose of doing an experiment over an observational study is to learn whether a certain condition causes a certain response.
Cause and effect can be defined as the relationship between two things or events in which an occurrence of one (cause) leads to the occurrence of another (effect).
if a/b = 2 /5, b/c = 3 /8, a/c =??
Answer:
3/20
Step-by-step explanation:
By question it's given that ,
[tex]\implies \dfrac{a}{b}=\dfrac{2}{5}[/tex]
[tex]\implies \dfrac{b}{c}=\dfrac{3}{8}[/tex]
And we need to find out the value of a/c .For that Multiply both of them , we have ;
[tex]\implies \dfrac{a}{b} \times\dfrac{b}{c}=\dfrac{2}{5}\times \dfrac{3}{8} \\\\\implies \dfrac{a}{c}= \dfrac{3}{20}[/tex]
Hence the required answer is 3/20 .

Step-by-step explanation:
1. What does each expression equation represent in this situation? Q(18) b. Q(30) = 27.5
Answer:
Step-by-step explanation:
Q(18) is a direction. It means that wherever you see a variable like x on the right, you put an 18 in for it. For example Suppose the right looked like
Q(x) = x^2 + 10 Then Q(18) would mean
Q(18) = 18^2 + 10
Q(18) = 324 + 10
Now we come to the second equation (b)
What that means is that after you do all the calculations, your answer is
27.5
So for the first question(a) Q(18) = 334
A is the direction of what to do. It is the question.
B is the answer

Hey is there any chance anyone could help me with this question ASAP?? Tysm :)
Answer:

Step-by-step explanation:
A = π. r²
36π = π. r²
eliminate π, we get:
36=r²
r=√36
r = 6
Answer:
r = 6
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Given A = 36π , then
πr² = 36π ( divide both sides by π )
r² = 36 ( take the square root of both sides )
r = [tex]\sqrt{36}[/tex] = 6
An on-demand movie company charges 52.95 per movie plus a monthly fee of $39.95. Which expression represents
the yearly cost for x movie rentals?

39.95x295
2958-39 95(12)
295x3995(12)
Hurry I'm being timed !
Answer:
52.95x + 39.95(12)
Step-by-step explanation:
Answer:
52.95 x + 39.95 (12)
Step-by-step explanation:
cost per movie = 52.95
a monthly subscription is 39.95 and there are 12 months in a year so it would be 39.95 x 12
the x would be dependent on the amount of movie rentals and therefore the cost of the rentals = 52.95 x
