Answer:
y = 6.93
Step-by-step explanation:
Given the Vertex and ficuas of a parabola as :
Vertex (0,0) ; focus(0,2) ; depth = 5 inches
Width of parabolic heater at its widest point :
General equation of a parabola:
4p(x - h) = (y - k)²
(h, k) = Vertex
hence,
h =0 ; k = 0 ; p = 2 ; x = 5
(y - k)² = 4p(x - h)
(y - 0)² = 4*2(6 - 0)
(y-0)(y-0) = 8(6 - 0)
y² = 48 - 0
y² = 48
y = 6.928
y = 6.93

You decide to go to the candy store in the mall. You arrive at the store with $25 and then purchase 3 candy bars. You then buy a giant candy snake for $12.50. When you leave, you have $8.75 left in your wallet. How much did each candy bar cost? Write the equation to represent the scenario. 8.75 - x - 12.50 = 25.00 25.00 - 3x - 12.50 = 8.75 25.00 - 3x - 8.75 = 12.50 25.00x - 12.50 = 8.75
Answer:
The cost of a candy is $1.25Step-by-step explanation:
given the total amount at hand is $25
let the price of candy be x
then the cost of 3 candy will be 3x
the cost of a candy snake is $12.50.
balance at hand after the end of buying $8.75
the total expenses summed up must equal the initial amount at hand which is $25
the expression for the scenario is 3x+12.5+8.75=25
3x+21.25=25
3x=25-21.25
3x=3.75
x=3.75/3
x=$1.25
The cost of a candy is $1.25
An emerald pendant was marked up 150% from an original cost of $488. Last Friday, Cameron bought the emerald pendant and paid an additional 5% in sale tax. What was his total cost?
Given parameters:
Mark up percentage = 150%
Original cost = $488
Sales tax = 5%
Unknown:
His total cost = ?
Solution:
Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.
Since the emerald was marked up by 150%;
New cost = (1 + 1.5) x $488 = $1220
Now, the additional tax was 5%;
Tax = [tex]\frac{5}{100}[/tex] x 1220 = $61
So, the total cost = New cost + tax = $1220 + $61 = $1281

Step-by-step explanation:
Two- fifths
Answer:
The answer is 2/5 (B)
Step-by-step explanation:
1/3 divided by 5/6
To solve, we need to multiply the reciprocal of the divisor (5/6 in this case)
The reciprocal of 5/6 is 6/5
1/3*6/5 = 6/15 which can be reduced to 2/5
The answer is 2/5 (B)

Solve for c.
a (c-b) = d
[tex]a(c - b) = d[/tex]
Divided sides by a
[tex] \frac{a}{a}(c - b) = \frac{d}{a} \\ [/tex]
[tex]c - b = \frac{d}{a} \\ [/tex]
Plus sides b
[tex]c - b + b = \frac{d}{a} + b \\ [/tex]
[tex]c = \frac{d}{a} + b \\ [/tex]
Done.....♥️♥️♥️♥️♥️
Answer:
[tex]c = \frac{ab + d}{a}[/tex]
Step-by-step explanation:
Step 1: Add ab to both sides.
−ab + ac + ab = d + ab
ac = ab + d
Step 2: Divide both sides by a.
[tex]\frac{ac}{a} =\frac{ab + d}{a}[/tex]
[tex]c = \frac{ab + d}{a}[/tex]

Find the value of a and b need help ASAP
Answer:
Step-by-step explanation:
<a = 85° ( Vertically Opposite Angles )
<b = 180 - 85 = 95° ( Adjacent Angles )
Hope this helps
Plz mark as brainliest!!!!!!!!
Answer:
<a=85
<b=95
Step-by-step explanation:
<a is going to be the same as the other angle is across from it. So <a equals 85 degrees. So now since we know that two parts are 85 degrees we add 85 + 85 and we get 170 degrees. Since the whole thing is 360 degrees we need to subtract the 170 degrees that we already have. So 360-170 is equal to 190 degrees. Now since <b is the same as the angle across from it is we just need to divide the remaining degrees in half. So we take the 190 degrees and divide that in half. When you divide that in half you get 95 degrees. So <b is 95 degrees.

Answer:
[tex]\angle 1=39\textdegree[/tex]
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle always equal 180. Therefore:
[tex]\angle 1+\angle Y+102=180[/tex]
Let's subtract 102 from both sides. This yields:
[tex]\angle 1+\angle Y=78[/tex]
Now, notice the that both ∠1 and ∠Y have exactly one arc mark.
Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:
[tex]\angle 1=\angle Y[/tex]
So, we can substitute ∠Y for ∠1 for our equation. This yields:
[tex]\angle 1+\angle 1=78[/tex]
Combine like terms:
[tex]2\angle 1=78[/tex]
Divide both sides by 2. So, the measure of our angle is:
[tex]\angle 1=39\textdegree[/tex]
And we're done!

What is the measure of ZBFA?
D
o
3x+4
2x+16
Ε
F
5x-10
В
A
Idk
Answer:
∠BFA = 50°
Step-by-step explanation:
To find∠ BFA we first have to find ∠BFE this is how we'll do it!
5x-10 + 3x+4 + 2x +16 = 180 (collect like terms)(5x+3x+2x)(-10+4+16)
10x + 10 = 180 (minus 10 on each side)
10x = 170 (divide by 10 on each side)
x = 17
Plug in. (Plug in the rest of the equations)
5(17)-10=75°
3(17)+4=55°
2(17)+16=50°
∠BFA would equal 50 degrees because it is vertical of ∠DFE.
When two angles are vertical to each other they equal the same amount or in other words they're congruent.

The temperature on Monday was 14 degree Celsius. On Tuesday the temperature decreased by 5 degree. On Wednesday, the temperature decreased another 10 degree. On Thursday the temperature increased by 8 degrees. What was the temperature at the end of the day on Thursday?
Answer:
7 degrees
Step-by-step explanation:
The temperature in Monday was 14 degrees
On tuesday the temperature decreased by 5 degrees
On Wednesday it decreased by 10 degrees
On thursday the temperature increased by 8 degrees
Therefore the temperature at the end of the day on Thursday can be calculated as follows
= 14 - 5 - 10 + 8
= 7
Hence the temperature at the end of the day on Thursday is 7 degrees

Answer:
x = 25
Step-by-step explanation:
3x + 5 + 5x - 25 = 180 (collect like terms)
8x - 20 = 180 (add 20 on both sides)
8x = 200 (divide by 8 on both sides)
x = 25
Since they are supplementary that mean together they add up to 180 so that's why I added them together.
