Answer:
B. 4
Step-by-step explanation:
The formula for this equation is (x-h)²+(y-k)²=r²
So 16 is represented by r² in that equation
All you have to do is find the square root of 16, which is 4, so the answer is B. 4
The radius of the circle represented by the equation (x + 7)² + (y + 7)² = 16 is 4 units.
Explanation:In mathematics, specifically in coordinate geometry, the standard form to represent a circle's equation is (x-h)² +(y-k)² = r², where (h,k) are the coordinates of the circle's center and r is the radius. Looking at the provided equation, (x + 7)² + (y + 7)² = 16, you can recognize this as following the same format. Here, h = -7, k = -7, and r² = 16. Therefore, the radius of the circle is the square root of 16, which equals 4. Therefore, the length of the radius of circle O is 4.

20. Helen and Carla live in states that have
different sales tax rates. They each bought
a new bicycle. Helen paid $14 for a 5.6%
sales tax on her bicycle. Carla paid $12 for
a 4.8% sales tax on her bicycle. Who paid
more for their bicycle, not including sales
tax?
Answer: Helen paid $250 for the bike
Carla paid $250 for the bike.
They both paid the same amount
Step-by-step explanation:
Final answer:
By calculating the pre-tax prices of the bicycles using the provided sales tax amounts and rates, we determine that both Helen and Carla's bicycles cost $250 before tax, meaning neither paid more for their bicycle excluding the sales tax.
Explanation:
To determine who paid more for their bicycle excluding the sales tax, we need to calculate the pre-tax price of each bicycle using the sales tax amounts given. This requires us to work backwards from the sales tax paid to the original cost of the item.
For Helen, we know that the sales tax was $14, and the rate was 5.6%. We find the pre-tax price by dividing the sales tax paid by the sales tax rate (converted into decimal form):
Pre-tax price for Helen = $14 / 0.056 = $250
For Carla, the sales tax was $12, and the rate was 4.8%. The pre-tax price calculation is similar:
Pre-tax price for Carla = $12 / 0.048 = $250
Since both pre-tax prices are equal, neither Helen nor Carla paid more for their bicycle when we do not include the sales tax.

Jordan went to the store to buy a bicycle that was advertised for $50. When he arrived, he learned that the model he wanted was sold out, but there was another bicycle available that cost 15% more. How much did the available bicycle cost before taxes? $7.50 $57.50 $65.00 $15.00
Answer: 57.50
Step-by-step explanation:
50*.15=7.50
50+7.5=57.50
B - $57.50
Step-by-step explanation:
To find the cost of the available bicycle before taxes, we need to add another 15% to the original $50. To do that, all you do is multiply $50 by 15%, and then re-add the $50. Work is shown below:
First, change 15% into a decimal:
15% -> 15/100 -> 0.15
Next, lets find the cost of the available bicycle:
x = 50 (0.15)
x = 7.5
Now add the $50 back 7.5:
50 + 7.5 = 75.50
So your answer is B = $57.50
What is the slope and x-intercept of y=2x+1?
Answer:
slope: 2
x-intercept = -1/2
Step-by-step explanation:
The equation is in y = mx + b form. m = slope. The slop is equal to 2.
To find the x-intercept set y equal to 0 and solve for x.
0 = 2x + 1
-1 = 2x
x = -1/2
Answer:
slope= 2
x intercept=-0.5 or -1/2
Step-by-step explanation:
y= mx+b
m is the slope, therefore 2 is the slope of the equation.
X-intercept
substitute 0 to y
0=2x + 1
Subtract 1 from both sides
0-1=2x+1-1
-1=2x
Divide both sides by 2
-1/2=2x/2
x=-1/2 or -0.5

The price of 8 citrons and 9 fragrant wood apples is 145 units. The price of 9 citrons and 8 fragrant wood apples is 144 units. Find the price of a citron and the price of a wood apple.
Answer:
The price of a citron is 8 and the price of a wood apple is 9
Step-by-step explanation:
First of all we make two equations that represents the problem
c = citrons price
w = wood apples price
8c + 9w = 145
9c + 8w = 144
we clear c in the first equation
8c + 9f = 145
8c= 145 - 9w
c = (145 - 9w) /8
c = 145/8 - 9w/8
we replace c by (145/8 - 9w/8) in the second equation and solve
9(145/8 - 9w/8) + 8w = 144
163.125 - 10.125w + 8w = 144
163.125 - 144 = 10.125w - 8w
19.125 = 2.125w
19.125/2.125 = w
9 = f
now we replace w in the first equation
8c + 9w = 145
8c + 9(9) = 145
8c + 81 = 145
8c = 145 - 81
8c = 64
c = 64 / 8
c = 8
The price of a citron is 8 and the price of a wood apple is 9

Find the equation of the hyperbola centered at the origin that satisfies the given conditions: x-intercepts = +,-4 and asymptote at y=3/4x
Answer:
The equation of the hyperbola is presented as follows;
[tex]\frac{x^2}{16} - \frac{y^2}{9} =1[/tex]
Step-by-step explanation:
Here we have the standard equation of an hyperbola given as follows;
[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} =1[/tex]
Where:
a = x intercept
The asymptote is ±(b/a)x
Since the intercept, a is ± 4, the vertices are (-4, 0) and (4, 0)
We are given the asymptote as y = 3/4x, therefore, since the genral form of the asymptote is ±(b/a)x, comparing, we have;
±(b/a)x ≡ 3/4x
We have a = ±4, therefore, b = 3
Hence the equation of the hyperbola is found by putting in the values of a and b in the general form as follows;
[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} =1 \Rightarrow \frac{x^2}{4^2} - \frac{y^2}{3^2} =1[/tex]
The equation of the hyperbola = x²/16 - y²/9 = 1.

Write your answers in simplest form.
slope:
E
Undefined
y-intercept:
Answer:
Y-intercept:3
slope: -6
Step-by-step explanation:
because the slope ends with x because that's what will go on the x line of a graph.and the y-intercept ends with y because that's how the number will increase.Hope it helps:)!
The equation -6x + 3y = -9 is rearranged to y = 2x - 3. The slope (m) is 2, and the y-intercept (b) is -3.
To find the slope and y-intercept of the line represented by the equation -6x + 3y = -9, we need to rearrange it into the slope-intercept form (y = mx + b), where m is the slope, and b is the y-intercept.
Step 1: Rearrange the equation:
-6x + 3y = -9
Add 6x to both sides:
3y = 6x - 9
Step 2: Solve for y:
Divide both sides by 3 to isolate y:
y = (6/3)x - (9/3)
y = 2x - 3
Now, the equation is in the slope-intercept form. The slope (m) is the coefficient of x, which is 2, and the y-intercept (b) is the constant term, which is -3.

Cost to store: $75
Percent of Markup:
Selling price: $112.50
Answer:
15%
Step-by-step explanation:
pretty sure thats right
Final answer:
The student's question involves a business math concept of calculating the percent markup from the cost and selling price, resulting in a 50% markup for this example.
Explanation:
The question involves calculating the percent markup based on the cost to store an item and its selling price.
To find the percent of markup, you subtract the cost to store from the selling price and then divide by the cost to store.
Finally, multiply by 100 to get the percentage.
For example, if an item costs $75 to store and sells for $112.50, the markup is ($112.50 - $75) / $75 = 0.50, or 50%.
This is an example of a basic markup calculation commonly covered in business and economics classes in high school.

James had a peach that was 98 mm in diameter. One day he watered it with a magical solution, and it grew to 188,869 mm
in diameter.
Approximately how many times as large did the diameter of the peach become after James watered it?
To determine how many times larger the peach got, you will divide the new diameter by the original diameter length.
188869/98 = 1927.2
The new diameter is approximately 1927 times longer.
To convert this to scientific notation, move the decimal point from the end (on the right) to between the 1 and the 9 to get 1.927.
Then count the number of decimal places you moved to get there, because this represents how many groups of 10 you adjusted your place value by and then becomes your exponent in scientific notation.
1.927 x 10^3 times is the answer in scientific notation.

A pedestal on which a statue is raised on is a rectangular concrete solid measuring nine
feet long, nine feet wide, and six inches high. How much is the cost of the concrete in the
pedestal, if concrete costs $70 per cubic yard?
Answer:
The cost of the rectangular concrete solid is $104.87Step-by-step explanation:
If the pedestal on which a statue is raised on is a rectangular concrete solid measuring nine feet long, nine feet wide, and six inches high, the volume of the rectangular concrete solid will be expressed as shown;
Volume of the rectangular concrete solid = Length * Width * Height
Given Length = 9ft, Width = 9ft and Height = 6inches
Converting all the units to yards
Given 1ft = 0.333yard
Length = 9 * 0.333 = 2.997yards
Width = 9* 0.333 = 2.997yards
Also given 1inch = 0.0278yard
Height = 6 * 0.0278yards = 0.1668yards
Volume of rectangular concrete solid in cubic yards = 2.997*2.997*0.1668
Volume of rectangular concrete solid in cubic yards = 1.4982cubic yards
If concrete costs $70 per cubic yard, the cost of the rectangular concrete solid will be 1.4982 *$70 = $104.87
