Answer:
x^2 + y^2 = 3^2
Step-by-step explanation:
Start with (x - h)^2 + (y - k)^2 = r^2.
If the center is at (0, 0), we then have x^2 + y^2 = r^2.
If this circle passes through (0, 9), then 0^2 + 9^2 = r^2, and r must be 3.
Then the standard equation of this circle i
x^2 + y^2 = 3^2
What is the area of kite ABCD?

Area=
[tex]\pi \times r {}^{2} [/tex]
1)To find radius diameter/2
21.5÷2=10.75
[tex]10.75 {}^{2} \times \pi = 362.87[/tex]
area =362.87cm
2)
[tex]\pi \times 13.2 {}^{2} = 547.39[/tex]
area=547.39cm
a)
Area = pie × ( 21.5 / 2 )^2
Area = pie × ( 10.75 )^2
Area = pie × 115.5625
Area = 3.14 × 115.5625
Area = 362.86625 cm^2

Answer:
16 kg/cm^2
Step-by-step explanation:
200cm^3=32kg/cm^2
1cm^3=32/200 kg per cm^2
So,100cm^2 =(32/200)x100
=16cm/kg^2

Answer:126m2
Step-by-step explanation:
Since they are both rectangles, use the area of a rectangle equation to find it which is length times width. What I would do first is find the area of the big rectangle which is 10*15 which is 150. Then I would find the area of the white space which is 6*4 which is 24. Since the white space is not part of the question, subtract 24 from 150 which gets you 126m2. Hope this helps :)
Aaron, Bonny and Connor are playing a game with cards.
Aaron has some cards.
Bonny has twice as many cards as Aaron.
Connor has 6 cards more than Bonny.
They have a total of 101 cards.
Work out how many cards Aaron has.
Let the number of cards Aaron has : A
Given :
⊕ Bonny has twice as many cards as Aaron
⊕ Connor has 6 cards more than Bonny
⊕ Total cards : 101
⇒ Number of cards Bonny has : 2A
⇒ Number of cards Connor has : 2A + 6
⇒ Aaron cards + Bonny cards + Connor cards = 101
⇒ A + 2A + 2A + 6 = 101
⇒ 5A = 101 - 6
⇒ 5A = 95
⇒ A = 19
Answer : Aaron has 19 Cards
Find The number to the angle QPR
Step-by-step explanation:
you know that QPS adds up to 47
so the sum of RPS and QPR shoukd = 47
(3x - 38) + (7x - 95) = 47
you then solve for x then you can use that to find QPR

HURRY IM BEING TIMED! The line of best fit for this scatter plot shows the relationship between the average temperature and the monthly electricity bill at Jenny’s house.
Answer:
[tex]y = \frac{11}{8}x + 50[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
The line of best fit
From the attached plot, we have:
[tex](x_1,y_1) = (0,50)[/tex]
[tex](x_2,y_2) = (80,160)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{160 - 50}{80-0}[/tex]
[tex]m = \frac{110}{80}[/tex]
[tex]m = \frac{11}{8}[/tex]
The line of best fit is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = \frac{11}{8}(x - 0) + 50[/tex]
[tex]y = \frac{11}{8}x + 50[/tex]
Answer:
The electricity bill will be about $200 when the average temperature reaches 100°F.
Round 8.157 to the nearest hundredth.
Answer:
I believe the answer is 8.16 pardon me if it's wrong.
Answer:
8.18
Step-by-step explanation:
First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 8
Fractional Part: 175
To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.
We use the following rules to round 8.175 to the nearest hundredth:
A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.
B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.
C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.
D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.
With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

An A grade will be given to students having at least 370 total test points. There is one more test to take before the semester is over. Lesha wants to know what she needs to score on the next test to finish with an A. Write and solve an equation to determine what score she needs to get. Explain your reasoning.
Answer:
95 points
Step-by-step explanation:
Given
[tex]n = 370[/tex] --- expected point
See attachment for points
Required
An inequality to determine the points needed
First, we calculate the points (p) Lesha has already accumulated.
[tex]p = Test\ 1 + Test\ 2 + Test\ 3[/tex]
[tex]p = 75 + 100 + 100[/tex]
[tex]p = 275[/tex]
Let the number of points needed be t.
So:
[tex]p + t = 370[/tex] ---- i.e. She must score a total of 370
Make t the subject
[tex]t = 370 -p[/tex]
Substitute 275 for p
[tex]t = 370 -275[/tex]
[tex]t = 95[/tex]

Last summer milo sold water bottles at the park to raise money for his baseball team he made the table below does the table shows a proportional relationship how do you know
Answer:
No
Step-by-step explanation:
For a proportional relationship :
y = kx
Where , k = constant of proportionality
Taking the first set of data:
x = 50 ; y = 10
10 = 50k
k = 10/ 50 = 1/5
Hence, the proportional equation or relation is :
y = 1/5x
Check if this is true for other data points on the data :
Taking the second data point :
x = 85 ; check if y will be 20
From :
y = 1/5x
y = 1/5*85
y = 85/5
y = 17
Since ;
y value from the equation isn't the same as that in the table, then the table does not show a proportional relationship.

Caculate the temperature change if 3456 J of thermal energy was transferred into 3.0 kg of lead? The specific heat of lead is 128 J/kgo C.
Answer:
9°C
Step-by-step explanation:
quantity of heat energy absorbed is expressed as;
Q = mcΔt
m is the mass
c is the specific heat capacity
Δt is the change in temperature
Substitute the given values
3456 = 3 * 128 Δt
3456 = 384Δt
Δt = 3456/384
Δt = 9°C
Hence the temperature change is 9°C
