if y=3 then 14y equals
Answer:
42
Step-by-step explanation:
14(3)
Answer:
42
Step-by-step explanation:
first, substitute 3 for y in 14y. 14y means you are multiplying 14 and y, so when you plug in 3 for y, you're multiplying 14 and 3! :)
14y ⇒ 14(3)simplify by multiplying 14 · 3.
14(3) = 42so, when y = 3, 14y = 42.
you can check the answer by solving for y in 14y = 42.
divide both sides of the equation by 14.
14y/14 = 1y or y42/14 = 3after dividing, you're left with y = 3. that means 14y does indeed equal 42 when y = 3! :)

When building a house, the number of days required to build is inversely proportional to with the number of workers. One house was built in 147 days by 4 workers. How many days would it take to build a similar house with 42 workers?
Answer:
14
Step-by-step explanation:
[tex]147 \times 4 \div 42 = 14[/tex]
It would take 14 days to build a similar house with 42 workers
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that the number of days required to build is inversely proportional to with the number of workers.
One house was built in 147 days by 4 workers.
So,
147 x 4 = 588
Now the days to build a similar house with 42 workers
588/ 42 = 14

I need help with this please
Answer:
x + 12 ft
Step-by-step explanation:
Area = base times height. Here we know the area (x^2 + 9x - 36) and the width (x - 3). Since area = length times width, divide the given area by x - 3.
x^2 + 9x - 36 factors into (x - 3)(x + 12).
Dividing this result by x - 3 yields the length: x + 12 ft
find the measure of angle A
Answer:
35 degrees
Step-by-step explanation:
Sum of angles inside a triangle is 180 degrees.
Right angle is 90 degrees.
180 = 90 + (x + 46) + (x + 66) = 2x + 202
x = -11
A = x + 46 = -11 + 46 = 35

A right triangle has legs measuring 5 feet and 12 feet. If the legs of the triangle were doubled, what would be the difference in the original and enlarged perimeters?
Answer:
[tex]30[/tex]
Step-by-step explanation:
1. Approach
First, use the Pythagorean theorem to solve for the hypotenuse of the given right triangle. Then find the perimeter by adding up the values of all the sides. The problem then has the lengths of the legs doubled. When the legs undergo a scaling factor, the hypotenuse and perimeter undergo the same scaling factor. Here, the legs are doubled, hence the hypotenuse and the perimeter are also doubled. Finally, subtract the new perimeter from the original perimeter.
2. Find the original hypotenuse
Remember the Pythagorean theorem states;
[tex]x^{2}+y^{2}=z^{2}[/tex]
Where (a) and (y) are the legs (or the sides adjacent to the right angle), and (z) is the hypotenuse or the side opposite to the right angle.
Substitute in the given value and solve,
[tex](5)^{2}+(12)^{2}=z^{2}\\\\25 + 144 = z^{2}\\\\169=z^{2}\\\\\sqrt{169}=z\\\\13=z[/tex]
3.Find the perimeter of the original triangle
To find the perimeter of a polygon, one must add up the lengths of all the sides.
[tex]5 + 12 + 13\\\\= 30[/tex]
4. Find the new perimeter
In a right triangle, when both legs undergo a scaling factor, the hypotenuse also has the same change, and the perimeter also undergoes the same change. In this case, the length of the legs is doubled, therefore, the hypotenuse and the perimeter are also doubled.
New hypotenuse; [tex]26[/tex]
New perimeter; [tex]60[/tex]
5. Find the difference
Now all that is left is to subtract the new perimeter from the original perimeter;
(New_perimeter) - (original_perimeter)
= [tex]60 - 30[/tex]
= [tex]30[/tex]

Can y’all help me on this question?
Answer:
134
Step-by-step explanation:
There's 2 blue arrows where 39 is, and the same arrows where 4x+7 are. This means that they are the same length. So, 4x+7 = 39. Perimeter means you add, so 28+28+39+39 = 134.
The diagram shows a 6 ft student standing near a tree. The shadow of the student and the shadow of the tree ends at point A. What is the height of the tree?
Answer: 18ft
Step-by-step explanation: I took the quiz and got 100%
The height of the tree is 8.3 ft.
To solve this problem, we have to find the angle of elevation from the student.
To do this, we have to assume or bring out a right angle triangle and solve for the.
Given that we have the distance of A to F and the point to F
A to F = 5ftE to F = 6angle ?Trigonometric RatioUsing trigonometric ratio,
We can find the tangent of this angle
[tex]tan\theta = \frac{opposite}{adjacent} \\tan\theta = \frac{6}{5}\\ tan \theta = 1.2\\\theta = tan^-^1(1.2)\\\theta = 50.2^0[/tex]
The angle of elevation can be calculated using sum of angles in a triangle is equal to 180 degrees
[tex]180 = 90 + 50.2 + x\\x = 180- 140.2\\x = 39.8^0[/tex]
Assuming a right angle triangle from the point the student is standing, the distance from him to the tree would be
[tex]15 - 5 = 10ft[/tex]
Let's use the tangent of the angle to find the height of the tree.
[tex]tan\theta = \frac{opposite}{adjacent} \\tan 39.8 = \frac{x}{10}\\x = 10 tan39.8\\x = 8.3ft[/tex]
From the calculations above, the height of the tree is 8.3 ft.
