Answer:
x = 57.2
Step-by-step explanation:
first : the third angle is (the sum of all angles in a triangle is always 180 degrees) : 180 - 90 - 40 = 50 degrees.
law of sines :
x/sin(50) = 48/sin(40)
x = 48 × (sin(50)/sin(40)) = 57.2

Mrs. Helton is making gift bags as prizes for her math classes. She has 30 little bags of Hershey Kisses and 15 Blow Pops. What is the greatest number of gift bags she can make if all gift bags are the same, and she does not want any left over?
Answer:
15
Step-by-step explanation:
For this we must find the GCF, or greatest common factor, because we cannot have multiples.
Factors of 30:
1 , 2, 3, 5, 6, 10, 15, 30
Factors of 15:
1, 3, 5, 15
GCF = 15
Each bag will have 2 Hershey bags, and 1 Blow Pop

The price of grapes at the grocery store is $1.44 per pound. There are approximately 0.45 kilograms in a pound. To the nearest cent, what is the price of grapes in dollars per kilogram?
$0.65 per kilogram
$0.99 per kilogram
$1.89 per kilogram
$3.20 per kilogram
Answer:
$3.20 / kg
Step-by-step explanation:
$1.44 / pound
so, this is normed to 1 pound = 0.45 kg.
now we want to transform that to have 1 kg as the norming unit.
for this we need to multiply the top and the bottom of the ratio with the same number, so that the value of the ratio remains unchanged, but that the bottom turns into 1 kg.
so, what do we need to turn 0.45 into 1 ?
0.45 × x = 1
x = 1/0.45 = 1/1 / 45/100 = 100/45 = 20/9 = 2.22222...
since we need to multiply top and bottom with the same factor, we get
(1.44/0.45) × (2.222222/2.222222) =
(1.44 × 2.222222) / (0.45×2.222222) =
(1.44 × 2.222222) / 1kg = $3.20 / kg
the answer is number 4 or d

A) (x-1)^3+ 3x(x-4)+2=x^3
B) x^3 +6x +12x +8=0
Answer: I'll solve A) since there is a lot of work to be shown.
Step-by-step explanation:
A)
(x−1)³+3x(x−4)+2=x³
Use binomial theorem to expand (x−1)³
x³- 3x² + 3x - 1 + 3x(x-4) + 2=x³
Use distributive property on 3x(x-4)
x³- 3x² + 3x - 1 + 3x²-12x + 2=x³
Add like terms
x³ −9x + 1 =x³
Subtract x³ from both sides.
x³ −9x +1 -x³ = 0
Add x³ and -x³
−9x+1=0
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
−9x=−1
Divide both sides by -9.
x= 1/9

Answer:
-3
Step-by-step explanation:
You have to bring -16 to the other side by adding.
It would make it: -7a=21
Then you hve to diving the -7.
-7a/-7=21/-7
That would equal -3
Answer:
A= -3
Step-by-step explanation:
-7a - 16 = 5
( -7a - 16) + 16 = 5 + 16
-7a - 16 + 16 = 21
-7a = 21
7a/7 = - 21/7
a = -3

9. Write an equation in slope intercept form that
passes through (6,2) and (-3.0)
Answer:
y = -2/9x+2/3
Step-by-step explanation:
First find the slope
m= (y2-y1)/(x2-x1)
= (0-2)/(-3-6)
= -2 /-9
2/9
The slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = 2/9x+b
Using the point -3,0
0 = 2/9(-3) +b
0 = -2/3+b
b = 2/3
y = -2/9x+2/3

Find x
A. 3√3
B. 6√3
C. 2√3 over 3
D. 3
Answer:
A, 3 root 3
Step-by-step explanation:
The triangle is a 30-60-90 Triangle meaning that the shortest side can be multiplied by 2 to get the hypotenuse or the slanted/longest side.
The second longest side of this triangle will always be the shortest side times root 3. Use the chart as a reference.
Answer:
3√3
Step-by-step explanation:
Angle ratio = 30 : 60 : 90
Side ratio = a : a√3 = 2a
Side opposite to 90° = 2a
2a = 6
a = 6/2
a = 3
Side opposite to 60° = a√3
x = a√3 =3√3

1.Given the function f(x) = -2c + cx - x^2? and f^-1(5) = -1, find c
Here we have a quadratic function and we want to find the value of a constant with a given restriction.
We will find that c = 8.
So we have the function:
[tex]f(x) = -2c + cx - x^2[/tex]
We know that:
[tex]f(5)^{-1} = -1 = \frac{1}{-2c + c\cdot 5 - (5)^2}[/tex]
Notice that the above equation means that:
[tex]-2c + c\cdot5 - (5)^2 = -1[/tex]
Then we just need to solve the above equation for c:
[tex]-2c + 5c - (5)^2 = -1\\\\(-2 + 5)\cdot c - 25 = -1\\\\3\cdot c = -1 + 25\\\\3\cdot c = 24\\\\c = 24/3 = 8[/tex]
So we found that the value of c is 8.
This means that the function is:
[tex]f(x) = -16 + 8\cdot x - x^2[/tex]

Which plane geometry has countless symmetry axis ? (except for circle)
Sorry if there are some grammatical mistakes in my question because English isn't my first language. Thank you very much !
Countless symmetry axis of a parabola is vertical line which divides the parabola into two congruent halves.
The axis of symmetry always passes through vertex of parabola. These will cause the plane to divide into two parts.
The geometric shape may have countless symmetry axis. This actually divides the shape into two halves and creates a mirror like effect.
The x-coordinate of vertex is equation of axis symmetry of parabola. Lets say if we take an example of quadratic equation which is ,

Find the slope (-2,5),(2,9)
Answer:
1
Step-by-step explanation:
Let,
x1 = - 2
y1 = 5
x2 = 2
y2 = 9
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 9 - 5 ) ) / ( 2 - ( - 2 )
= 4 / 4
= 1
Answer:
slope is 1
Step-by-step explanation:
from (-2, 5) to (2,9)
slope m= (y2-y1) / (x2-x1) = (9-5) / (2- -2) = 4 / 4 =1
*
you can think of how do you get from one point to the other
first point (-2, 5) go to second point (2,9)
-first on the y-axis (vertical) you start at 5 and go four up to get to 9
-second on the x-axis (horizontal) you start at -2 and go four right to get to 2
slope = change in y / change in x = four up /four right = 4/4 = 1
-moving down or to the left will make the numbers negative
