how many boys perfer the ferris wheel?

Answers

Answer:

10 Boys

Step-by-step explanation:

10 boys prefer the Ferris wheel because the total amount of boys is 35, but 23 of those 35 boys prefers the Super Slide, meaning what's left is who prefers the Ferris wheel since there are only 2 options for them to choose from.

35 boys - 23 boys (who like the Super Slide) = 10 boys (the remainder who likes the Ferris wheel).

A restaurant customer left ​$ as a tip. The tax was and the tip was ​% of the after tax cost. Which information is not needed to compute the bill after tax and​ tip? What was the total​ bill?

Answers

Complete question :

A restaurant customer left ​$0.90 as a tip. The tax was 8% and the tip was ​10% of the after tax cost. Which information is not needed to compute the bill after tax and​ tip? What was the total​ bill?

Answer:

The tax percentage

9.9

Step-by-step explanation:

Guven that :

Amount of tip left = 0.90

Tip left = 10% of after tax cost

Tax % = 8%

If tip left = 10% of after tax cost; then ;

If after tax cost = x

10% of x = 0.90

0.1x = 0.9

Hence the percentage tax isn't needed :

To obtain the total bill:

Let total bill = y

y = after tax cost and tip

Hence,

y = x + tip

y = x + 0.9

From : 0.1x = 0.9 ; x = 0.9/0.1 = 9

Hence,

Total bill:

y = 9 + 0.9

y = 9.9

I WILL GIVE BRAINLIEST IF CORRECT The area of a square is 49 square centimeters. Find the length of a side. Find the length of the
diagonal

Answers

Answer: 7

Step-by-step explanation:

Since squares have the same side lengths

then you need to find a number that multiplies twice that equals 49

7*7 = 49

Answer: Length of a side: 7 / Length of the diagonal: 9.9

Explanation:

Just square root 49, so it becomes 7. That's the side length. In order, to find the diagonal of the square, just use Pythagorean Theorem, a^2+b^2=c^2. Because it's a quadrilateral, all of the sides should equal 7. a^2 would be 7 and b^2 would be 7. 49+49=98. Square root 98 and you would get 9.899... That would be estimated to 9.9.

Step-by-step explanation:

Let's solve this together!

First you would want to multiply 6 and x:

6×2 = 12

x×2 = 2x

Then you would want to subtract 12 from 3:

Vertical Line Test - Tells us if a graph is a functionVertical Lines - slopes are undefined

Step-by-step explanation:

If the slope m was equal to 0, then it would be a horizontal line rather than a vertical line.

Using the Vertical Line Test, we also know that the graph is not a function.

Usually a vertical line has an undefined slope, as x equals a certain number, and m = unknown.

Answer: It's undefined, because it's vertical
