A class has 12 girls and 18 boys. What is the probability that a boy raises his hand and asks to go to the bathroom given a girl already left the room to go to the bathroom?

Answers

Answer 1

Answer:

The answer is  [tex]\frac{18}{29}[/tex]

Explanation:-

Total number of students = 12 + 18 = 30

Total number of students after one girl left = 29

Number of boys = 18

Probability that a boy raises his hand and asks to go to the bathroom =

Number of boys divided by total number of students

[tex]\frac{18}{29}[/tex]

A 25 foot ladder is set against the side of a house so that it reaches up 15 feet. If Camden grabs the ladder at its base and pulls it 3 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 12 ft.) Round to the nearest tenth of a foot.

Answers

Answer:

The ladder will reach a height of 9.8 foot

Step-by-step explanation:

Given

Initial Position

[tex]L = 25ft[/tex] --- Length of the ladder

[tex]h = 15ft[/tex] --- height against the wall

New position

[tex]L = 25ft[/tex] --- Length of the ladder

[tex]B = 3ft[/tex] --- 3 feet farther from the wall

Required

Determine the new height the ladder will reach

The question is illustrated using the attached image.

Where

[tex]\triangle ABC[/tex] represents the initial position of the ladder

[tex]\triangle DBE[/tex] represents the new position of the ladder

The new height is represented with BD

Using Pythagoras theorem on [tex]\triangle DBE[/tex]

[tex]DE^2 = BE^2 + BD^2[/tex]

[tex]BE = BC + CE = 20 + 3 = 23[/tex]

[tex]BD = x[/tex]

[tex]DE =25[/tex] --- length of the ladder

So, the expression becomes

[tex]25^2 = 23^2 + x^2[/tex]

[tex]625 = 529 + x^2[/tex]

Collect like terms

[tex]x^2 = -529 + 625[/tex]

[tex]x^2 = 96[/tex]

Take positive square roots of both sides

[tex]x = \sqrt{96[/tex]

[tex]x = 9.8ft[/tex] --- approximated

Answer:

9.8 FT

Miko's work is not shown in this question. Regardless, her process of using multiplication to check her work is correct. When performing a division problem, you can multiply the quotient by the divisor and the product of this multiplication process should be equal to the dividend of the division problem. For example,

Tori has a cell phone plan that charges $0.09 for each text message sent. Tori plans to spend no more than $40 per month on texting bill each month. If c(t) = 0.09t represents the total
mumber of text (that you send each month.
The domain of the function is x

Answers

Answer: [tex]t<444.44[/tex]

Step-by-step explanation:

Given

Texting bill is given by [tex]c(t)=0.09t[/tex]

Spending must be less than [tex]\$40\ \text{per month}[/tex]

So, text billing must be less than $40

[tex]\therefore 0.09t<40\\\\\Rightarrow t<\dfrac{40}{0.09}\\\\\Rightarrow t<444.44[/tex]

he levels of mercury in two different bodies of water are rising. In one body of water the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year.

Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury?

0.05 – 0.1y = 0.12 – 0.06y
0.05y + 0.1 = 0.12y + 0.06
0.05 + 0.1y = 0.12 + 0.06y
0.05y – 0.1 = 0.12y – 0.06
