Should be pretty easy to answer, I just need a refresher. I forgot how to solve for triangles...
Answers
Answer:
25.734
Step of explanation:
tanjent =opposite/adjacent
cosine =adjacent /hypotenuse
sine =opposite /hypotenuse
this use tangent because the opposite number is there and we want to find adjacent
so t =opposite /adjacent
tan25 °=12/ a
a=12/tan25
=25.734

[tex]372100[/tex]
Step-by-step explanation:
A number to the [tex]x[/tex] power represents [tex]x[/tex] amount of times the number is multiplied by itself. To the second power means that the number is multiplied by itself twice.
[tex][(20\times30)+10]^2 = 610^2[/tex] (first work on terms inside parentheses)

If 16 horses eat 5 stacks of hay in 35 days, how many horses can eat 4 stacks of hay in 8 days? Math question
Answers
Answer:
The number of horses that can eat 4 stacks of hay in 8 days = 56 horses
Step-by-step explanation:
The given parameters are;
The time it takes 16 horses to eat 5 stacks = 35 days
Therefore;
The time it takes 16 horses to eat 5/5 stacks (1 stack) = 35 days/5 = 7 days
The time it takes 16 horses to eat 1 stack of hay = 7 days
The time it takes 16 horses/16 to eat 1 stack of hay = 7 days × 16 = 112 days
Therefore;
The time it takes 1 horse to eat 1 stack of hay = 112 days
The time it takes 1 horse to eat 4 × 1 stack of hay = 112 days × 4 = 448 days
The time it takes 1 horse to eat 4 stacks of hay = 448 days
Therefore, given that (448 days)/(8 days/horse) = 56 horse, we have;
The number of horses that will eat 4 stacks of hay in 8 days = 56 horses.

Solve the system of equations by elimination.
2x - y + 3z=-1
x + 2y - 4z=-1
y – 2z=0
Answers
Answer:
x = -1, y = 2 and z = 1
Step-by-step explanation:
The given system of equations are :
2x - y + 3z= -1 ....(1)
x + 2y - 4z = -1 ......(2)
y – 2z = 0 .....(3)
Equation (3) can be written as :
y = 2z
Use y = 2z in equation (2)
x + 2(2z) - 4z = -1
x + 4z - 4z = -1
x = -1
Put the value of x in equation (1) :
-2 -y +3z = -1
-y+3z = 1 ....(4)
Adding equation (3) and (4)
y-2z+(-y+3z)=1
z = 1
Now put z = 1 in equation (4)
-y+3=1
-y = -2
y = 2
Hence, the values of x,y and z are -1, 2 and 1 respectively.
I’m helping my brother with his homework and I’m confused. Would this be split into 1/2 for each pizza or 1/4 like shown in the photo?
Answers
Answer:
1/2
Step-by-step explanation:
1/2 because if you divide 2 pizzas into 4 then you can get 4 1/2s.
if you slice the pizza into fourths then each person will get 2/4rts and which is the same thing as 1/2 only 1/2 is simplified.

The length of each side of an equilateral triangle is 74 mm, correct to the nearest millimetre.
Calculate the smallest possible perimeter of the triangle.
Answers
Answer:
222mm
Step-by-step explanation:
The perimeter of a triangle is the sum of all of the sides. This triangle is equilateral, which means that all sides are equal and in this case, each side is 74mm. So to find the perimeter of this triangle add each, 74+74+74, which equals 222. Therefore, the answer must be 222mm.
Answer:
the answer is 222 mm.

You are painting your room. You mix 1/4 cup of red paint for every 1/2 cup of paint.
A.If you need to make 3 gallons of purple paint, how much red paint will you add?
B. How much blue paint would you need?
C. Make a ratio table to show the amounts of red and blue paint that can be added to make different amounts of purple paint.
Answers
Answer:
a- 2/5 + 1/4=.65 mixture of red and blue paint
(2/5) / .65 X 1.625=1 gallon of red paint
(1/4) / .65 X 1.625=5/8 gllaons of blue paint, because
1 + 5/8=1 5/8 gallons of purple paint.
b-1/10 + 2/5 + 1/4=.75 mixture of white, red and blue paint
(1/10) / .75 X 3/8= 1/20 gallons of white paint
(2/5) / .75 X 3/8=1/5 gallons of red paint
(1/4) / .75 X 3/8=1/8 gallons of blue paint, because
1/20 + 1/5 + 1/8=3/8 gallons of lighter purple paint.

help me: [tex]\int\limits^\pi _0 sin({x}) \, dx[/tex]
Answers
Answer:
[tex]\int^{\pi}_{0}sin(x)dx = 2[/tex]
Step-by-step explanation:
To solve for the value of [tex]\int^{\pi}_{0}sin(x)dx[/tex], we need to first find the antiderivative of [tex]sin(x)[/tex].
Since the derivative of [tex]cos(x)[/tex] is [tex]-sin(x)[/tex], therefore the derivative of [tex]-cos(x)[/tex] is [tex]sin(x)[/tex]. With this:
[tex]\int^{\pi}_{0}sin(x)dx = -cos(\pi)-(-cos(0))[/tex]
[tex]=-cos(\pi)+cos(0)[/tex]
[tex]=-(-1)+1[/tex]
[tex]=2[/tex]
∴ [tex]\int^{\pi}_{0}sin(x)dx = 2[/tex]
