the ratio of girls to boys in an astronomy club was 3:2. there were 30 girls. how many total members were there in the club
Answer:
Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42
Step-by-step explanation:
The University of Central Florida is planning to build a new access ramp for wheelchairs at its education building. The main entrance to the building is 4 feet above the sidewalk level. The angle of elevation from where the ramp and sidewalk would meet is 8.1°. Determine the length of the ramp to the nearest tenth of a foot.
Answer:
0.6 feet
Step-by-step explanation:
We solve this question using the Trigonometric function of Tangent.
tan θ = Opposite/Adjacent.
Where:
Opposite = Height /Length of the ramp = ?
Adjacent = Distance from the base of the ramp = 4 feet
θ = 8.1°
Therefore,
tan 8.1° = x/4
Cross Multiply
x = tan 8.1 × 4
x = 0.5692843028 feet
Approximately = 0.6 feet
Length of the ramp = 0.6 feet.

if a car travels 120 miles in 4 hours. what is its speed per hour
Answer:
v = 30 km/h
Step-by-step explanation:
Given that,
Distance covered by a car, d = 120 miles
Time, t = 4 hours
We need to find the speed of the car. The speed of an object is equal to the distance covered divided by the time taken. It can be given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{120\ \text{miles}}{4\ \text{hour}}\\\\v=30\ \text{mph}[/tex]
So, the speed of the car is 30 km/h.

Answer:
[tex] - 3 < x \leqslant 2[/tex]
Answer:
-3<p<2
Step-by-step explanation:
simplify the equations below
Answer:
Problem 1: 1/64x^8
Problem 2: y^8/9x^2
Step-by-step explanation:
In the first problem, you first need to multiply the -2 exponent to everything in the parenthesis. This is equal to 1/64x^4*-2, simplified to be 1/64x^-8. Finally you simplify the x to 1/64x^8.
For the second problem, you do the same in the first one, getting x^-2/9y^4*-2. This can be simplified to be 3x^-2/y^-8. Finally you make sure there is no negative exponents, so you do y^8/9x^2.
Answer:
1/64x^8 and y^8/9x^2
Step-by-step explanation:
hope this helps have a good night :)
Parallel lines j and k are cut by transvesal t . Which statement is true about ∠2 and ∠6
Answer:
They both equal
Step-by-step explanation:
The statement is true about ∠2 and ∠6 is corresponding angles.
What is line?A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
Given:
Parallel lines j and k are cut by transversal t .
We have to find statement is true about ∠2 and ∠6.
According to given question we have
Parallel lines j and k are cut by transversal t .
So,
∠2 = ∠6 ( corresponding angles)
∠1 = ∠5 ( corresponding angles)
Therefore, the statement is true about ∠2 and ∠6 is corresponding angles.

The parabola in the figure below has an equation of the form
y = ax^2 + bx - 4.
Find the equation of the parabola
Answer:
y = - x² + 5x - 4
Step-by-step explanation:
Given that the zeros are x = 1 and x = 4 , then the corresponding factors are
(x - 1) and (x - 4) , then
y = a(x - 1)(x - 4) ← a is a multiplier
= a(x² - 5x + 4)
To find a substitute the coordinates of any other point on the parabola into the equation.
Using (2, 2), then
2 = a(4 - 10 + 4) = - 2a ( divide both sides by - 2 )
a = - 1
Thus
y = - (x² - 5x + 4) = - x² + 5x - 4 ( with a = - 1 and b = 5 )

The black graph is the graph of y=f(x). Choose the equation for the red graph.
Answer:
y-1 = f(x)
Step-by-step explanation:
Here, we want to choose the equation for the ref graph
The red graph as we can see is above the black
This means it is more positive
The difference between the two is just 1 unit
By the addition of 1 to the y-value of the black graph, we get the red
Thus, we have that;
y- 1 = f(x)
Suppose that 18 inches of wire costs 72 cents.

Answer:
[tex]56[/tex] cents
Step-by-step explanation:
If [tex]18[/tex] inches of wire cost [tex]72[/tex] cents, then each inch of wire will cost [tex]\frac{72}{18}=4[/tex] cents. Therefore, 14 inches of wire will cost [tex]14*4=56[/tex] cents. Hope this helps!
Answer:
56 cents
Step-by-step explanation: 72 cents divided by 18= 4 so for one inch of wire it cost 4 cents Then 14 inches times 4= 56 I think thats

Complete the square for the following equation x^2-18x
Answer:
Multiple answers would work
Step-by-step explanation:
From the subtraction sign before the 18x, we can infer that one of the equations has a negative number. So, know we have this:
(x-?) (x+?)
There are multiple answers this could be,
(x-18) (x)
(x-20) (x+2)
You get where I am going...
If you went with the first on (x-18) (x), then you wouldn't have to add anything.
(x-20) (x+2) = x^2 - 18X - 40.
To be honest this one stumped me. Some just have multiple answers. My guess is that you have to fill out the boxes so maybe the first answer wouldn't work.
Sorry I couldn't give a concise answer. Though their probably is one obivious answer that I am missing.
