A 10 meter ladder is leaned up against a building. If
the angle of elevation is 60 degrees, what is the
height of the building?
Answer:
8.7
Step-by-step explanation:
Use trigonometry. The ladder and the building form a right triangle with the ground. You are given the length of the hypotenuse and the base angle. You use sine since we are trying to figure out the opposite side from the angle and we have the hypotenuse length. Sin = opposite/hypotenuse. So in this case, sin 60°= x/10. We solve for x by multiplying both sides by 10. Now x= sin 60° (10) = (0.8660)(10) = 8.7 m.
Can multiplying two fractions result in a product smaller than either one of the factors?
Explain your answer using at least three examples.
Answer:
Yes, it can. For example, 2/3 x 1/8 = 2/24; 9/10 x 5/6 = 45/60, and 3/8 x 4/5 = 12/40. These products are less than all the factors of the equations.

13) A Super Bowl Party Sub was cut into 3 equal pieces that were x inches long. Kevin took
6 inches of the sub for himself. There was still 30 inches of the sub when the game started.
How many inches was each of the pieces?
Answer:
12 inches
Step-by-step explanation:
now i am assuming kevin took 6 inches of the sub before the game because it says "there was still 30 inches of the sub when the game started". In that case, add 6 and 30 to get 36. Because the sub was cut into 3 equal pieces, divide 36 by 3 and get 12 inches as your final answer.

What is the value of -x squared -4x-11 if x=-3
Answer:
-32
Step-by-step explanation:

The total area of the two triangles is _____ square inches.
Numerical Answers Expected!
Answer:
140 square inches
Step-by-step explanation:
10 times 6 is 60
and 10 times 80 is 80
and add that equals 140

Answer:
70 square inches
Step-by-step explanation:
Forget the coloring and look at the outline of the figure. You see it is a trapezoid with bases 6 in (top) and 8 in (bottom). The height is given as 10 in.
The area formula for a trapezoid is ...
A = (1/2)(b1 +b2)h
A = (1/2)(6 in +8 in)(10 in) = (1/2)(14)(10) in²
A = 70 in²
The area of the figure is 70 square inches.
_____
Alternate solution
You can add the areas of the two triangles. The area of each is ...
A = (1/2)bh
Gray triangle: A = (1/2)(8 in)(10 in) = 40 in²
Brown triangle: A = (1/2)(6 in)(10 in) = 30 in²
Total area = 40 in² + 30 in² = 70 in²
__
If you're paying attention to the formulas, you see that the "alternate solution" computes ...
A = (1/2)(b1)h + (1/2)(b2)h = (1/2)(b1 +b2)h . . . . . trapezoid formula

What are the 2 answers?
Answer:
7060Step-by-step explanation:
by solving inequality :
x-3 <70x < 73so the value of x should be less than 73.
so required values are 70 and 60
70 and 60 are the correct answers. If you take 70 and subtract 3 you get 67, which is less than 70. If you take 60 and subtract 3 you have 57, which is less thna 70. Basically any number that is 72 or less would be a coorect answer

Qal o valor de G?
6(−2g−1)=−(13g+2)
Answer:
The value of g is [tex]g = 4[/tex](o valor é [tex]g = 4[/tex]).
Step-by-step explanation:
We solve the equality to find the value of G.
First we apply the distributive property, then we isolate g.
[tex]6(-2g - 1) = -(13g+2)[/tex]
[tex]-12g - 6 = -13g - 2[/tex]
[tex]-12g + 13g = -2 + 6[/tex]
[tex]g = 4[/tex]
The value of g is [tex]g = 4[/tex](o valor é [tex]g = 4[/tex]).

Find the 18h term of the arithmetic sequence whose common difference is d=4 and whose first term is a, =3.
Answer:
the 18th term is 71
Step-by-step explanation:
The general form for any term "n" in an arithmetic sequence is:
a(n) = a1 + (n-1) * d
where "d" is the common difference.
So, in our case we have:
a(n) = 3 + (n-1) *4
Therefore, the 18th term will be:
a(18) = 3 + (18 - 1) 4 = 3 + 17 * 4 = 71
