Kara bought two birthday gifts for her twin nephews. Each gift cost $12.50. Sales tax was
8.5%. What was the total cost for the gifts, including tax?
Answers
Answer:
$27.12
Step-by-step:
So, we first need to learn how much money the tax is. We can find it like this
8.5 8.5x12.50
------ x 12.50 = ----------------
100 100
106.25
= ------------- = 1.0625 ~~ $1.06
100
The tax is $1.06
So now, the only thing left is to add
12.50 + 1.06 = $13.56
13.56x2 = $27.12 (for both gifts)
In total, both gifts cost $27.12 with tax.
In total, both gifts cost
Which of these is the standard form of the following function?
f(x) = -9(x + 5)2 + 4
f(x) = 9x2 − 90x − 221
f(x) = -9x2 − 90x − 221
f(x) = 9x2 − 180x + 221
f(x) = -9x2 − 180x − 221
Answers
Answer:
We conclude that the standard form of the given function is:
[tex]f(x)=-9x^2-90x-221[/tex]
Hence, option B is correct.
Step-by-step explanation:
We know that the standard form of the quadratic function is of the form
[tex]f\left(x\right)\:=\:ax^2\:+\:bx\:+\:c[/tex]
Given the function
[tex]f(x)=-9\left(x\:+\:5\right)^2\:+\:4[/tex]
as (x+5)² = x² + 10x + 25
[tex]f(x)=-9\left(x^2+10x+25\right)+4[/tex]
Expanding -9(x² + 10x + 25) = -9x² - 90x - 225
[tex]f\left(x\right)\:=-9x^2-90x-225+4[/tex]
simplifying
[tex]f(x)=-9x^2-90x-221[/tex]
Therefore, we conclude that the standard form of the given function is:
[tex]f(x)=-9x^2-90x-221[/tex]
Hence, option B is correct.

The cost to manufacture a hair clip is $0.50. With a markup of 200%, what is the selling price of this hair clip?
Given data
cost to manufacture a hair clip is $0.50
markup of 200%
Required
The selling price
We know that
Mark up percent= selling-cost/cost*100
200= selling-0.5/0.5*100
200-selling= 50/0.5
200-selling= 100
selling= 200-100
selling = 100
Hence the selling price is $100

Find the value of X.
Answers
Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°

The diameter of a circle is 9 cm. Find its area to the nearest tenth.
Answers
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area
Answer:
63.6
Step-by-step explanation:
1. A = πr²
2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5
3. Now that we know the radius, we plug it into our formula: A = π(4.5)²
4. Simplify: A = 3.14(20.25)
5. A = 63.62
6. Rounding to the nearest tenth makes your answer 63.6
