To repair a roof that is 16 feet high, Mr. Ayala leans a 20-foot ladder against the side of the
building. To reach the roof, how far away from the building should he place the base of the
ladder?
1
Answer:
12
Step-by-step explanation:
20 is the hypotenuse and 16 is the leg, first solve 20^2 (20x20) to get 400 and 16^2 (16x16) to get 256, then subtract the leg from the hypotenuse to obtain 144 (400 - 256) then obtain the square root of 144 ([tex]\sqrt{144}[/tex]) then 12 will be the awnser.

Answer:
? = 4.28
Step-by-step explanation:
We know that tan theta = opp side / adjacent side
tan 35 = 3 / ?
Multiply each side by ?
? tan 35 = 3
Divide each side by tan 35
? = 3/tan 35
?= 4.28444402
To the nearest hundredth
? = 4.28

Work out the perimeter of the shaded shape.
If 5x−4y=22 and 3x+6y=30, what is the value of x−5y
Answer:
-4 See Below:
Step-by-step explanation:
When you have a system of equations, you need to solve for one variable, and subsitute that variable into the other equation to solve for the other variables value.
3x +6y = 30 In this case, it would be easier to solve for x.
3x= 30-6y Divide both sides by 3
x= 10-2y
Now we substitute for x in the other equation.
5x- 4y = 22
5(10-2y)-4y=22
50-10y-4y=22
50-14y=22 Add 14y to both sides
50= 14y + 22 Subtract 22 from both sides
28 = 14y Divide by 14 on both sides.
y = 2
Substitute y=2 and solve for x.
x = 10- 2y
x= 10-2*2
x= 10-4
x= 6
Now we know y=2 and x=6, so we can substitute them into x-5y to find its value.
x - 5y
= 6-5*2
=6-10
= -4

Pytagora's Theorem
Step-by-step explanation
a = 4 m
b = 15 m
c = ?
a^2 + b^2 = c^2
√ a^2 + b^2 = c
a^2 = 16 m
b^2 = 225 m

W sklepie spożywczym jest 11,73 kg cukierków czekoladowych. Pierwszy klient kupił 48 dag cukierków. Drugi klient kupił 4/5 pozostałej ilości. Resztę cukierków, w równych ilościach, kupiło trzech ostatnich klientów. Po ile cukierków czekoladowych dostali ostatni klienci?
Answer:
The last costumers got 2.25 kilograms of chocolate candies.Step-by-step explanation:
The question is
There is 11.73 kg of chocolate candies in the grocery store. The first customer bought 48 dag of candies. A second customer bought 4/5 of the remaining quantity. The last three customers bought the same amount of candy. How much chocolate did the last customers get?
Givens
The total amount of chocolate candies is 11.73 kilograms.First costumer bought 48 dag of candies. (1 kg equals 100 dags)Second costumer bougth 4/5 of the remaining.Another three costumers bought the same amount of candy.Let's transform 48 dag to kilograms.
[tex]48dag \times \frac{1kg}{100dag}= 0.48 \ kg[/tex]
Therefore, the first costumer bought 0.48 kilograms of candies.
The remaining amount is: [tex]11.73kg-0.48kg=11.25kg[/tex]
Now, we need to multiply the remaining amount of candies with 4/5
[tex]\frac{4}{5} \times 11.25kg=9 \ kg[/tex]
Therefore, the second costumer bought 9 kilograms of chocolate candies.
At last, we need to find the new remaining part of candies, which is
[tex]11.25-9=2.25 \ kg[/tex]
Therefore, the last costumers got 2.25 kilograms of chocolate candies.

In the first equation in the system of equations, y represents the money collected from selling sweatshirts. In the second equation, y represents the money spent to produce x sweatshirts with team logos on them for a professional sports league. What does the solution of the system represent in this context?
y=35x
y=-0.05(x-400)^2+9,492
the number of sweatshirts that generate the maximum income
the number of sweatshirts that generate the minimum cost
the number of sweatshirts for which the difference between cost and income is greatest.
the number of sweatshirts for which cost and income are equal
Answer:
The number of sweatshirts for which cost and income are equal
Step-by-step explanation:
Let y₁ represent the revenue from selling "x" sweatshirts and y₂ represent the cost of producing "x" sweatshirts, solving the system:
[tex]y_1=35x\\y_2=-0.05(x-400)^2+9,492\\y_1=y_2\\35x=-0.05(x-400)^2+9,492\\-0.05(x-400)^2-35x+9,492=0[/tex]
The solution of the equation above yields the number of sweatshirts for which the cost of production (y₂ ) is equal to the revenue from sales (y₁).
Therefore, the solution represents the number of sweatshirts for which cost and income are equal .
The number of sweatshirts for which cost and income are equal and this can be determined by using the substitution method.
Given :
In the first equation in the system of equations, y represents the money collected from selling sweatshirts. In the second equation, y represents the money spent to produce x sweatshirts with team logos on them for a professional sports league.The following steps can be used in order to determine the solution of the system of the equation:
Step 1 - Write the given system of equations.
[tex]y = 35x[/tex] ---- (1)
[tex]y = -0.05(x - 400)^2+9492[/tex] ---- (2)
Step 2 - Now, substitute the value of 'y' in equation (2).
[tex]35x = -0.05(x - 400)^2+9492[/tex]
Step 3 - Simplify the above equation.
[tex]35x = -0.05x^2-8000+40x+9492[/tex]
Step 4 - Now, write the above equation in generalized quadratic form.
[tex]0.05x^2-5x-1492=0[/tex]
From the above steps, it can be concluded that the correct statement is given by option D).

Explain how you could write a quadratic function in
factored for that would have a veres with an
coordinate of 3 and two distinct roots,
Answer : the vertex lies on the axis of symmetry, so the axis of symmetry is x=3. Find any two x-intercepts that are equal distances from the axis of symmetry. Use those x-intercepts to write factors of the function by subtracting their values from x. For example, 2 and 4 are each 1 unit from x=3, so f(x)=(x-2) (-4) is a possible function.
Answer:
Step-by-step explanation:
The vertex lies on the axis of symmetry, so the axis of symmetry is x=3. This is correct.
Note that the second half of this problem has already been answered correctly. The axis of symmetry is precisely halfway between the two roots and has equation x = 3 in the case of x = 2 and x = 4.

Which of the following is not a step when drawing an angle?
A. Draw perpendicular lines
B. Draw a ray
C. Make a mark at the correct point on the protractor
D. Connect the mark and the vertex with a line
Answer:
A. Draw perpendicular lines
Step-by-step explanation:
Perpendicular lines are lines that intersect at a 90 degree angle. Unless you are constructing a right angle - or 45 degree angle - you would not need to draw perpendicular lines.
Therefore, answer A is correct.
