You bought a package of paper for $3 and some pencils for $2 each at the school store. You paid $15 for everything that you bought. How many pencils did you buy?

Answer:

The center:(20,0.05)

Radius: 9 units

Step-by-step explanation:

Rewrite the equation- (x-20)^2+(y-0.05)^2=81

(x-20)^2+(y-0.05)^2=9^2

Answer:

[tex]\displaystyle [20, \frac{1}{20}][/tex]

Explanation:

In a circle equation of [tex]\displaystyle [x - h]^2 + [y - k]^2 = r^2,[/tex]the centre of the circle is represented by [tex]\displaystyle [h, k],[/tex]hence, you have your answer.

x-3 y-4

Step-by-step explanation:

graph the points. It should look like a triangle without the bottom.

Answer:

a) 3/13

b) 1/2

Step-by-step explanation:

a) In a deck of 52 cards there are 4 Kings, 4 Queens and 4 jacks. So the probability of drawing those cards is (4+4+4)/52 = 12/52 = 3/13.

b) 1/2 because the numbers greater than 3 on a dice is 4, 5, and 6 which is half of the available options.

Answer:

Step-by-step explanation:

Here the function is y = 5x.

If x = -2, y = 5(-2) = -10;

If x = 0, y = 5(0) = 0; and

If x = 9, y = 5(9) = 45

And so on

Answer:

x=15

Step-by-step explanation:

Like solving all Algebra equations, it is very important to make sure that the variables (In this case x) are on one side and the numbers are on the other side.

85-3x=40

First, let's subtract 40 on both sides

45-3x=0

Add 3x to both sides

45=3x

Let's divide both side by 3

And we get...

x=15

Step-by-step explanation:

to find a radius of any diameter just find half of the diameter

Answer: it's A

Step-by-step explanation: took the test

Answer:

502.4ft^3

Step-by-step explanation:

Given data

Height= 10ft

radius= 4 ft

Hence the volume for the cylinder can be gotten as

v= πr^2h

v= 3.14*4^2*10

v=3.14*16*10

v=502.4ft^3

Therefore the volume of the cylinder is 502.4ft^3

Answer:

The answer is 18.

Step-by-step explanation:

40 * 0.45 = 18

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

Hope this helps

6x + 18, that is the answer

Answer:

35

Step-by-step explanation:

Create a proportion where x is the number of Warrior fans

[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{21}[/tex]

Cross multiply and solve for x

105 = 3x

35 = x

So, there were 35 Warrior fans

Answer:

[tex] \bf\huge warrior \: fans = 35[/tex]

Step-by-step explanation:

finding the warrior fans

⟼ warrior : laker fans = 5 : 3 = x : 21

⟼ 5 : 3 = x : 21

⟼ [tex]\frac{5}{3} \times \frac{x}{21} [/tex]

⟼ x = 5 × 7

⟼ x = 35.

⟼ warriors fans = 35.

∴ laker fans is 21 and warriors fan is 35.

∴ warriors : laker fans = 5 : 3 = 35:21.

Answer:

14.2604

Step-by-step explanation:

this is because 22% as a decimal would be 0.22, and since this is out of 64.82, you have to multiply 0.22 by 68.82

Answer:

I = $ 1,080.00

Step-by-step explanation:

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.6%/100 = 0.036 per year,

then, solving our equation

I = 7500 × 0.036 × 4 = 1080

I = $ 1,080.00

The simple interest accumulated

on a principal of $ 7,500.00

at a rate of 3.6% per year

for 4 years is $ 1,080.00.

Answer:

33

Step-by-step explanation:

The two angles add up to 180 degrees because a straight line is 180 degrees

Add both equations and set equal to 180

3m + 138 + 7m +12 = 180

Algebra yeet

Simplify

10m +150 = 180

10m = 30

m = 3

Angle DBC is (7m + 12):

Substitute m = 3

7(3) + 12 = 21 + 12 = 33 degrees

Answer:

The probability of landing on 8 twice is 1/64

Step-by-step explanation:

If you spin the spinner once, there are 8 possibilities each time (1-8). The possibility of landing on the number 8 is 1 of these 8 possibilities. Its probability is therefore 1/8

Each spin is independent. In other words, the spins do not affect each other. The number you land on during the first spin does not impact the second spin's number. The probability of landing on 8 the second time is the same as the first time: 1/8

Because the two events are independent, we find the probability of them both occurring by multiplying them together.

1/8 times 1/8= 1/64
