The radius of a circle is increasing. At a certain instant, the rate of increase in the area of the circle is numerically equal to twice the rate of increase in its circumference. What is the radius of the circle at that instant
Answer: [tex]2\ \text{units}[/tex]
Step-by-step explanation:
Given
Rate of increase in area of the circle is numerically equal to twice the rate of increase to twice the rate of increase in its circumference.
It can be written as
[tex]\Rightarrow \dfrac{d(\pi r^2)}{dt}=2\times \dfrac{(2\pi r)}{dt}\\\\\Rightarrow 2\pi r\dfrac{dr}{dt}=4\pi \dfrac{dr}{dt}\\\\\Rightarrow r=2\ \text{units}[/tex]
A store is having a 20% off sale. The final sale price of the items will include 5% sales tax.
The final sale price of an item can be expressed as 1.05(x – 0.2x), where x is the original price of the item.
Answer:
0.84 and 84
Step-by-step explanation:
1.05 (x -0.2x) = 1.05 (1-0.2)x = 1.05 * 0.8 x= 0.84x
84% of the original price of item
Answers:
first box = 0.84xsecond box = 84=================================================
Explanation:
Think of x - 0.2x as 1x-0.2x. The numbers out front, the 1 and -0.2, combine to 0.8
The 0.8 converts to 80%, meaning that if there's a 20% off sale, then you still have to pay the remaining 80% of the original price.
The 1.05 indicates that we started with 100%, and then add on 5% sales tax, so 100% + 5% = 1 + 0.05 = 1.05
---------------
Simplifying the expression given to us leads to
1.05(x - 0.2x)
1.05(1x - 0.2x)
1.05(0.8x)
(1.05*0.8)x
0.84x
This shows that the final price, after tax, is 84% of the original price.
In circle O, PQ is a tangent and PRT is a secant. If angle P is 56 degrees and arc QT is 192 degrees, what is the measure of arc QR(type in numbers only)
Answer:
80, I got it right so you should get it too
pleaseee helpp im giving away good points
Answer:
x = 1°
Step-by-step explanation:
Bisection means splitting the angle in to 2
So that means 4x-1 = 2x+1
4x-1 = 2x +1
4x = 2x + 2
2x = 2
x = 1°

Answer:
The right answer is "3.33333".
Step-by-step explanation:
The given points in the question are:
[tex]P=(7,-3) = (x_1,y_1)[/tex]
[tex]Q=(x,\frac{3}{6-x} )=(x_2,y_2)[/tex]
Now,
The slope of PQ will be:
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By putting the values, we get
= [tex]\frac{\frac{3}{6-x}+3 }{x-7}[/tex]
= [tex]\frac{3+18-3x}{(6-x)(x-7)}[/tex]
= [tex]\frac{21-3x}{(6-x)(x-7)}[/tex]
= [tex]\frac{3(x-7)}{(6-x)(x-7)}[/tex]
= [tex]\frac{3}{x-6}[/tex]
hence,
x = 6.9
it's slope will be:
= [tex]3.33333[/tex]
2. Brandon has 4 1/2 cups of oats. He uses 3 1/4 cups to make oats for a camping trip. He saves the rest of the oats to feed to his bird, Coco. If Coco needs ¼ of a cup of oats each day, how many days can Brandon feed Coco with the oats he has left? Answer must be a whole number
4 1/2 - 3 1/4
.= 9/2 - 13/4
= 18-13/4
= 5/4 cups
= 5/4 cups ÷ 1/4 cups
= 5/4 × 4/1

Suppose a cookie company has found that the number of cookies it sells is inversely proportional to the price of each cookie. If it sells 50 cookies per day when the price of each cookie is $4, how many cookies would it sell per day if the price of each cookie were $2?
Answer:
Step-by-step explanation:
The inverse proportional formula is
[tex]y=\frac{k}{x}[/tex] where y is the number of cookies sold, and x is the price per cookie. If we fill in the info given, we can find what it is we are being asked.
When x = 4 (the price of each cookie is $4), 50 cookies are sold (y = 50). Filling in to solve for k:
[tex]50=\frac{k}{4}[/tex] so
k = 200. Using that value of k along with a price of 2 (x = 2), we can find the number of cookies sold, y.
[tex]y=\frac{200}{2}[/tex] so
y = 100 cookies sold when the price is $2 per cookie.

what is the slope of the equation -5x + 8y = 30?
Answer:
The slope is 5/8
Step-by-step explanation:
-5x+8y = 30
Add 5x to each side
8y = 5x+30
Divide by 8
8y/8 = 5/8x+30/8
y = 5/8x + 15/4
This is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is 5/8
Answer: 5/8
Step-by-step explanation:
You would first need to put the equation into standard form. so you add 5x on both sides
Then you divide 8 on both sides
that would give you y=5/8x+3.75
The slope is 5/8

were 285 students
chosen at random, and
the following results were recorded. What is the probability that a student who does not have a cell phone is from grade 11?
Using it's concept, it is found that there is a 0.6 = 60% probability that a student who does not have a cell phone is from grade 11.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Researching the problem on the internet, it is found that there are 30 students with no cell phones, and of those, 18 are in grade 11, hence the probability is given by:
p = 18/30 = 0.6.
0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

The slope of line passing through (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
A line passes through (-2, 7) and (3, 2). We need to find the slope.
x₁=-2, x₂=3, y₁=7, y₂=2
substitute the values in formula of slope
m=2-7/3-(-2)
m=-5/5=-1
The slope intercept form of line is y=-x+b
To find b put the values of (-2,7)
7=-(-2)+b
7=2+b
7-2=b
5=b
y intercept is 5
Hence the slope of line passing through (-2, 7) and (3, 2). is -1 and the value of the y-intercept b is 5.
