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). -100
B). -10
C). -3
D). 3
E). 10

Answers

Answer:

2 ( 3m -10) (3m+10)

Step-by-step explanation:

18m^2-200

Factor out 2

2 ( 9m^2 -100)

We recognize that this is the difference of squares ( a^2 -b^2) = (a-b)(a+b)

2 ( ( 3m)^2 - 10^2)

2 ( 3m -10) (3m+10)

Sheila is taking medicine to help fight an infection. The function f(x) = 12(0. 82)^x models the amount of a 12-mg dose of antibiotic left in her bloodstream after x hours.

About how many mg are left in her bloodstream after 2 hours?

Answers

Given:

[tex]f(x)=12(0.82)^x[/tex]

where, f(x) is the amount of a 12-mg dose of antibiotic left in her bloodstream after x hours.

To find:

The remaining mg in her bloodstream after 2 hours.

Solution:

The amount of a 12-mg dose of antibiotic left in her bloodstream after x hours is represented by the function

[tex]f(x)=12(0.82)^x[/tex]

Putting x=2, we get the remaining mg in her bloodstream after 2 hours.

[tex]f(2)=12(0.82)^2[/tex]

[tex]f(2)=12(0.6724)[/tex]

[tex]f(2)=8.0688[/tex]

Therefore, the remaining mg in her bloodstream after 2 hours is 8.0688 mg.

2(6-x)=3 please help

Answers

It’s impossible what are you doing Distributed property or solving for x?

Answer:

x = 4.5

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:

3+12 = 9

Then divide 9 by 2:

9÷2 = 4.5

x=4.5

That's it!

Hope this helped! :)

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.

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

At the baseball game, the Gregory's bought 5 hot dogs and 2 hamburgers and paid $27.00. The Hart's purchases 3 hot dogs and 4 hamburgers and paid $29.50. How much does 1 hot dog cost?

Answers

Answer:

1 hot dog costs $3.50

Step-by-step explanation:

Represent Hot dog with x and Hamburger with y

Gregory's purchase:

[tex]5x + 2y = 27[/tex] --- (1)

Hart's purchase:

[tex]3x + 4y = 29.5[/tex] ---- (2)

Required

Find x

To do this, we'll make use of the elimination method of solving simultaneous equation.

Start by multiplying (1) by 2

2 * ([tex]5x + 2y = 27[/tex])

This gives:

[tex]10x + 4y = 54[/tex] ---- (3)

Subtract (2) from (3)

[tex]10x + 4y = 54[/tex]

- ([tex]3x + 4y = 29.5[/tex])

-------------------------

[tex]7x = 24.5[/tex]

Solve for x

[tex]x = \frac{24.5}{7}[/tex]

[tex]x = 3.5[/tex]

Hence:

1 hot dog costs $3.50
