Find a.
Round to the nearest 10th.
its not 46.5!!
Answer:
a = 24
Step-by-step explanation:
sin 12° / 10 = sin 150° / a
cross-multiply:
a · sin 12° = 10 · sin 150°
a = 5 / sin 12°
a = 24
Answer:
a = 24

When solving this system by elimination, which variable is the most convenient to eliminate,
x or y?
2x + y = 7
3/2 x - y = 7/2
Answer:
Y is the appropriate variable and the most easiest and convenient to eliminate
name 2x + y = 7 as equation i
and 3/2 x - y = 7/2 as equation ii
then add equation i and ii together
(3/2 + 2) x + y - y = (7 + 7/2)
(7/2) x = (21/2)
x = 3
then put in x = 3 in equation i
4 + y = 7
x = 7 - 4
x = 3
Therefore x = 3 and y = 3

Mega Movies hosted a film premiere on Friday night. They charged $7 for adults and $4 for
children. Ninety-four adults and children attended, and $592 was made in ticket sales. How
many children and how many adults went to the film premiere?
Answer:
72 adults
22 children
Step-by-step explanation:
Let c = no. of children
a = no. of adults
Then 4c = total sales for the children and
7a = total sales for the adults
So, a + c = 94 and 7a + 4c = 592
-4a - 4c = -376
3a = 216
a = 72 adults
72 + c = 94
c = 22 children

Find the HCF of terms and factorise: 20x3 – 40x2 + 80x
Answer:
The largest factor that can be pulled out of that expression is 20x, giving you 20x(x² - 2x + 4)
Step-by-step explanation:
20x³ - 40x² + 80x
= 20x(x² - 2x + 4)
Use words and symbols to describe the value of each term as a function of its position. Then find the value of the twelfth term in the sequence.
Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: N + 9
N is equal to 12 in this equation
12 + 9 is 21.
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is 12(12)= 144
Hope this helps!

Find the volume of the sphere.
Either enter an exact answer in terms of pie or use 3.14 for Pie
Please please help me
Answer:
The volume of a sphere is 4/3 * πr³
With a radius of 3, you've got:
4/3 × π3³
= 4/3 × π × 27
= 4 × π × 9
= 45π

Expand and simplify (x+3)(x-4)
Answer:
Step-by-step explanation:
Use FOIL method.
F - First ; O - Outside ; I - inside ; L - last
(x + 3)(x - 4) = x*x + x*(-4) + 3*x + 3*(-4)
= x² - 4x + 3x - 12
= x² - x - 12
2 examples of a commutative property?
Answer:
hope this helps :)
Step-by-step explanation:
Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4.

Write an equation in point-slope form for the line through the given point with the given slope. (3,−4);m=−14
Answer:
y=-14x-4
Step-by-step explanation:
Answer:
y + 4 = - 14(x - 3)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = - 14 and (a, b ) = (3, - 4 ) , then
y - (- 4) = - 14(x - 3) , that is
y + 4 = - 14(x - 3)

The ratio of two supplementary angle is 3:1. Find the measures of both angles.
Answer:
The sum of two angle is 180 (supplementary)
given angle = 3:1
first angle =3x
2 nd angle=1x
3x+1x =180
4x =180
x = 180/ 4
x = 45
so first angle =3x x = 45
= 3×45
= 135 degree
2nd angle = 1x
=45 degree
ans
Both angles are 135 and 45

Carter bought 3/4 yard of fabric for an art project. He used 3/8 yard of the fabric. What fraction of a yard of fabric does Carter have left?
Answer:
3/8
Step-by-step explanation:
He purchased 3/4 yard of fabric, then used 3/8 of it. You would need to subtract the 3/8 from 3/4 because the fabric is being used up.
If f(x)=x+5, what is f-'(x)?
Step-by-step explanation:
Given
f(x) = x + 5
Let
y = f(x)
y = x + 5
Interchanging the roles of x and y we get
x = y + 5
y = x - 5
f^-1 (x) = x - 5

write a short explanation of why the distance formula works and include a discussion of why either point can be point 1 or point 2
Answer:
Finding the distance between two distinct points on a plane is the same as finding the hypotenuse of a right triangle. From this perspective, the distance formula states that the distance of two distinct points on a plane is equal to the square root of the sum of the square of the rise and run.
