Here is some information from the practice round for several new Click Bots.
Determine the missing values. Enter them in the table.
Then describe your strategy.
Answer/Step-by-step explanation:
✅Azure:
Clicks = 17
Time (secs) = 2
Unit rate (clicks/sec) = [tex] \frac{17}{2} = 8.5 [/tex]
✅Bronze:
Clicks = 38
Time (secs) = 4
Unit rate (clicks/sec) = [tex] \frac{38}{4} = 9.5 [/tex]
✅Camson:
Clicks = 26
Time (secs) = ? = x
Unit rate (clicks/sec) = 10.4
Thus: [tex] \frac{26}{x} = 10.4 [/tex]
Multiply both sides by x
[tex] 26 = 10.4*x [/tex]
Divide both sides by 10.4
[tex] \frac{26}{10.4} = x [/tex]
[tex] 2.5 = x [/tex]
Time (secs) = x = 2.5
✅Desert:
Clicks = ? = x
Time (secs) = 4.2
Unit rate (clicks/sec) = 8.33
Thus: [tex] \frac{x}{4.2} = 8.33 [/tex]
Multiply both sides by 4.2
[tex] x = 8.33*4.2 [/tex]
[tex] x = 34.986 [/tex]
Clicks = x ≈ 35
✅ Emerald:
Clicks = 3
Time (secs) = ? = x
Unit rate (clicks/sec) = 7.5
Thus: [tex] \frac{3}{x} = 7.5 [/tex]
Multiply both sides by x
[tex] 3 = 7.5*x [/tex]
Divide both sides by 7.5
[tex] \frac{3}{7.5} = x [/tex]
[tex] 0.4 = x [/tex]
Time (secs) = x = 0.4
✅Fuschia:
Clicks = ? = x
Time (secs) = 0.75
Unit rate (clicks/sec) = 8
Thus: [tex] \frac{x}{0.75} = 8 [/tex]
Multiply both sides by 0.75
[tex] x = 8*0.75 [/tex]
[tex] x = 6 [/tex]
Clicks = x ≈ 6

Amita's kitchen is rectangular with an area of 3 and 3/4 square meters the width of the kitchen is 1 and 1/2 m what is the length in meters of Anita's kicthen
Answer:
2 1 ÷ 2
Step-by-step explanation:
Given that
The kitchen of Amita would be a rectangular area contains 3 and 3 ÷ 4 square meters
And, the width of her kitchen is 1 and 1 ÷ 2 meter
So based on the above information, the length of Amita kitchen is
Here you divide the rectangular area by the width
= (3 and 3 ÷ 4) ÷ (1 and 1 ÷ 2)
= 2 and 1 ÷ 2
Hence, the length in meters of Anita's kitchen is 2 and 1 ÷ 2

Answer:102.22
Step-by-step explanation:
Answer:
2.22%
Step-by-step explanation:
Recall that year 1, the base year, has a CPI of 100.
From question 1, we know that the CPI of year 2 is 102.22.
To find the rate of inflation, find the percent change from year 1 to year 2:
102.22-100= 0.0222, or 2.22%

A seesaw is in balance when a weight times its distance on one side of the fulcrum is equal to another weight times its distance on the other side of the fulcrum. In the diagram, the 20-lb. weight is 5 feet from the fulcrum and another weight is 8 feet from the fulcrum. Using the in-balance seesaw shown, find the number of pounds in the weight represented by N.
Answer:
12.5
Step-by-step explanation:
The 20 lbs on the left side time the 5 feet is equal to 100.
You need the weight on the right side to equal 100 when it is multiplied to it's length from the fulcrum, which is 8.
All you need to do is divide 100 by 8, to get 12.5.

Jason invests $325 in a bank account. The bank has an annual
interest rate of 24%. How much interest did his investment earn
after one year?
The amount of interest earned by Jason is $78.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.
Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.
Given that Jason invests $325 in a bank account. The bank has an annual interest rate of 24%.
The interest will be calculated as:-
SI = ( P x R x T ) / 100
SI = ( 325 x 24 x 1 ) 100
SI = $78
Hence, the simple interest is $78.
