. A bag contains 7 orange beads, 3 red beads, and 5 white beads. What is the probability of
drawing a white bead?
Answer:
Work shown below!
Step-by-step explanation:
White bead = [tex]\frac{5}{15} =\frac{1}{3}[/tex]
Answer:
a 33.3333333% chance
Step-by-step explanation:
we do 7+3+5= 15 (the denominator)
and so the amount of white beads in total is 5/15
5÷15+100= 33.333333333 and so on percent

Write the equation of a line passing through the given point that is
perpendicular to the given line. 3.x – 8y = 16; (-3, 1)
Answer:
-8x-21=3y or -8/3x-7=y or 8x+y+21=0
Step-by-step explanation:
First find the slope of 3x-8y=16.
3x-16=8y (divide both sides by 8 so that y is isolated)
3/8x-2=y The slope is 3/8. The perpendicular slope is the negative reciprocal of 3/8, which is -8/3
Using the points, the equation of the line can be found.
(-8/3=y-1/x-(-3))3(x-(-3) (3(x-(-3) is the common denominator
This equals -8x-24=3y-3, add three to both sides which equals -8x-21=y.
The other answers are written in slope y-intercept form and general form.
*Note: x-(-3) can be written as x+3
Find a formula for the n th term, T n , of the following arithmetic sequence: 13 , 17 , 21 , 25 , . . . Hence, or otherwise, find the value of the 40th term, T 40 .
Answer:
tₙ = 4n + 9 t₄₀ = 169Step-by-step explanation:
17-13=4 and 21-17=4 and 25-21=4 so d=4
[tex]t_n=t_1+d(n-1)\\\\t_1=13\\d=4\\\\t_n=13+4(n-1)\\\\t_n=13+4n-4\\\\\underline{t_n=4n+9}[/tex]

In order to write the equation of the line passing through the point (-2, 2) that is parallel to the line y = 2x + 3 , the next step is to find the y-intercept of the perpendicular line. What is the y-intercept of the perpendicular line through point (-2, 2)?
Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
Answer:
See below.
Step-by-step explanation:
This question makes no sense.
Here is the question. Pay attention to the words in boldface.
"In order to write the equation of the line passing through the point (-2, 2) that is parallel to the line y = 2x + 3 , the next step is to find the y-intercept of the perpendicular line. What is the y-intercept of the perpendicular line through point (-2, 2)?"
Is the question asking for the parallel line or the perpendicular line?

The dividend is 5 1/6
The divisor is 5 1/6
The dividend is second number in this equation.
The quotient is correct.
Step-by-step explanation:
the dividend divided by the divisor equals the quotient
The dividend is [tex]5\frac{1}{6}[/tex] and the divisor is [tex]2\frac{5}{12}[/tex] and the quotient is [tex]2\frac{4}{29}[/tex]. Therefore, option A is the correct answer.
The given equation is [tex]5\frac{1}{6}\div2\frac{5}{12} =2\frac{4}{29}[/tex].
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Here,
[tex]5\frac{1}{6}\div2\frac{5}{12} =2\frac{4}{29}[/tex]
⇒ 31/6 ÷ 29/12 = 62/29
⇒ 31/6 × 12/29 = 62/29
⇒ 62/29 = 62/29
Here, the dividend = [tex]5\frac{1}{6}[/tex] and the divisor = [tex]2\frac{5}{12}[/tex] and the quotient = [tex]2\frac{4}{29}[/tex]
Therefore, option A is the correct answer.

Which shows two expressions that are equivalent to (Negative 7) (Negative 15) (Negative 5) Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go. If Yan made 8 stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan climbed?
Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)
Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years. They both purchased new cars this year. When will they next both purchase new cars in the same year?
Answer:
12 years
Step-by-step explanation:
Given that Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years.
Assuming that they purchase new cars together after n years.
So, n must a multiple of 4 as well as multiple 6, i.e the number n is the lowest multiple (LCM) of 4 and 6.
As LCM od 4 and 6 is 12, so n=12.
Hence, after 12 years they will purchase news cars together.

Answer:
[tex]p=39.4[/tex]°
Step-by-step explanation:
[tex]4a+4+75+p=180[/tex] (The sum of angles on a triangle is [tex]180[/tex]°)[tex]4a+p=180-4-75[/tex]
[tex]4a+p=101[/tex]
[tex]p+9a+2=180[/tex] (Angles of a straight line sums to [tex]180[/tex]°)
[tex]p + 9a = 178[/tex]
Elimination can be used to find the value of one variable:
[tex]p+9a-(4a+p)=178-101[/tex]
[tex]5a = 77[/tex]
[tex]a=15.4[/tex]
Now, the value of [tex]p[/tex] can be found by using substitution:
[tex]4a+p = 101[/tex]
[tex]4(15.4)+p=101[/tex]
[tex]p = 101-61.6[/tex]
[tex]p = 39.4[/tex]

The number of candies in the box is between 80 and 100. It is possible to divide all the candies among 2, 3 or 5 children. How many candies are in the box?
Answer:
90
Step-by-step explanation:
The number of candies can be divided among 2, 3, or 5 children so that is the same as saying: the number of candies must be divisible by 2, 3, and 5. In order for a number to be divisible by 5, it must end in 0 or 5 so we know the number of candies must end in 0 or 5. For a number to be divisible by 2, the number must end in an even number. 5 is not an even number so we know the number of candies must end in 0. If a number is divisible by 3, the digits added are divisible by 3. Go through each number(80, 90, 100) and see which one is divisible by 3. 90 is divisible by 2, 3, and 5.
Proof that 90 is divisible by 2, 3, and 5:
90 ÷ 2 = 45
90 ÷ 3 = 30
90 ÷ 5 = 18
The results are all whole numbers.
Express each rate as a unit rate. Round to the nearest tenth when necessary.
