Janet rolls a regular eight-sided die with numbers 1 to 8.
1/5
1/8
5/8
7/8
Answer:
The correct option is (b).
Step-by-step explanation:
We need to find the probability of getting 5 when Janet rolls a regular eight-sided die with numbers 1 to 8.
The formula for probability of getting an event is given by :
[tex]P=\dfrac{Favourable\ outcome}{Total\ no\ of\ outcomes}[/tex]
Here, favourable outcome = 1
Total outcomes = 8
So,
[tex]P=\dfrac{1}{8}[/tex]
So, the correct option is (b).

Kelly had a part-time job last year. She paid the state $234 in income tax. The state income tax rate is 5.2%. How much did Kelly earn?
Answer:
$4500
Step-by-step explanation:
Find how much she earned by dividing 234 by 0.052
234/0.052
= 4500
So, she earned $4500
Answer: see below
Step-by-step explanation:
Divide 234 by 5.2 to get one percent of her earnings, $45.
Multiply 45 by 100 to get 100% of her earnings, $4,500
If it asking for the gross earnings, leave it at $4,500
If it is asking for net earnings, subtract 234 from 4500 to get $4,266

Step-by-step explanation:
Let's say n is equal to f(x). So "n is equal to g(x) and g(x) is equal to 3c + f(x) - 15 so when
n = 9 and c = 4 when I substitute I get 3(4) + (9) - 15 = 12 + 9 -15 = 21 - 15 = 6
The sum of the measures of two angles is 90° one angle has a measure of 32.8° the other angle is represented by X what is the measure of the second angle
Answer:
x = 57.2
Step-by-step explanation:
Equation:
32.8 + x = 90
x = 90 - 32.8
x = 57.2
Sara invested a total of $1,014 by purchasing shares of two types of stock, stock A and stock B. she purchased 52 shares of stock A and 65 shares of stock B. if the combined cost for one share of stock A and one share of stock B is $17.18 find the cost per share of stock B
Answer: I think the answer might be 9.28.
Step-by-step explanation:
I was also confused with this question so I might be wrong.
Using the information provided above I was able to conclude that two possible equations you can form is A+B=17.18, where there is only 1 stock from company A and 1 stock from company B. The other equation is 52A+65B=1,014 since this is the total amount she spend on the stocks.
You can use Desmos to graph both of the equations or solve it by hand. If solving it by hand chose which method you wanna use wether it is elimination or substitution. (I would explain the process, but I am lazy)

The problem he solved is given. Complete the
four blanks shown for one of his steps and the
solution
Step-by-step explanation:
Here are the steps required for Solving Quadratics by Factoring:
Step 1: Write the equation in the correct form. To be in the correct form, you must remove all parentheses from each side of the equation by distributing, combine all like terms, and finally set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
Example 1 – Solve: x2 + 16 = 10x
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

What is the measure of angle CBD? ° What is the length of segment CD? cm Which trigonometric ratio can be used to compare BC to CD using angle CBD? What is the approximate length of BC? cm What is the approximate length of BD? cm
Answer:
Answer: The measure of ∠CBD is 36°. The length of segment CD is 6 cm.
The trigonometric function gives the ratio of different sides of a right-angle triangle. The length of the segment CD will be equal to 12cm (60/5).
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
1. For a regular pentagon, the measure of an internal angle is equal to 108°, therefore, the measure of ∠ABD is 108°.
2. Since the line CB is bisecting ∠ABD, therefore, the measure of the ∠CBD is 54°.
3. The length of the segment CD will be equal to the length of a side of the pentagon, therefore, the length of the segment CD will be equal to 12cm (60/5).
4. The trigonometric ratio that can be used to compare BC to CD using ∠CBD is Tangent.
5. The approximate length of BC can be determined as,
Tan(54°)=CD/BC
BC = CD/Tan(54°)
BC = 8.719 cm
6. The approximate length of BD can be determined using the Pythgorus theorem,
BD² = CD² + BC²
BD = 10.5835 cm

Calcule el décimo termino de una progresión geométrica que Los términos son 32 , 16 , 8 , 4 ................,
Respuesta:
1/16
Explicación paso a paso:
Dada la secuencia geométrica: 32, 16, 8, 4 ................,
El enésimo término de una progresión geométrica se obtiene mediante la relación:
enésimo término = ar ^ (n-1)
Dónde ; a = primer término = 32; n = enésimo término; r = razón común
r = a2 / a1 = a3 / a2
r = 16/32 = 8/16
r = 1/2
Por lo tanto, el décimo término:
n (10) = 32 * (1/2) ^ (10 - 1)
n (10) = 32 * (1/2) ^ 9
n (10) = 32 * (1/512)
n (10) = 32/512
n (10) = 1/16
Por lo tanto, el décimo término es 1/16

A box contain 10 green pins 3 are blue and 7 are green. Two pins are randomly taken out of the box without replacement work out the probability that both pins are the same color
Answer:
[tex]P(Z)=\frac{8}{15}[/tex]
Step-by-step explanation:
From the question we are told that:
Sample size [tex]n=10[/tex]
Green pins [tex]x=7[/tex]
Blue pins [tex]y=3[/tex]
Generally the probability of getting two green is mathematically given by
[tex]P(2X)=\frac{7}{10}*\frac{6}{9}[/tex]
[tex]P(2X)=\frac{7}{15}[/tex]
Generally the probability of getting two blue is mathematically given by
[tex]P(2Y)=\frac{3}{10}*\frac{2}{9}[/tex]
[tex]P(2Y)=\frac{1}{15}[/tex]
Therefore the probability that both pins are the same color P(Z)
[tex]P(Z)=P(2Y)+P(2X)\\P(Z)=\frac{7}{15}+\frac{1}{15}[/tex]
[tex]P(Z)=\frac{8}{15}[/tex]

De un depósito se gasta primero la mitad del agua, y luego la cuarta parte de lo que quedaba. Al final,
quedan 12 litros. Hallar la capacidad del depósito.
Answer:5/8 fraction of the deposit has been spent, which is 20 liters
Let "a" be the initial amount of water, then first half the water is used: then a / 2 of water is used and the other half is left at / 2 * (1/4), then the fourth part is used: then 1/8 * a is used, so now it remains: a / 2 - a / 8 = 3/8 * a, so 5/8 * a has been used, then what remains are 12 liters:
3/8 * a = 12 L
a = 12 L * 8/3 = 32 L
Wasted: 32 L - 12 L = 20 L

Maleah turned on the water in the kitchen. For every 1 3/4 minute, 1 2/3 gallons of water went into the sink. How many gallons of water filled the sink per minute?
Answer: 20/21 gallons
Step-by-step explanation:
From the question given, we are informed that Maleah turned on the water in the kitchen and that for every 1 3/4 minute, 1 2/3 gallons of water went into the sink.
The number of gallons of water that filled the sink per minute will then be calculated as:
= Amount of gallons of water that went into sink / Number of minutes used
= 1 2/3 ÷ 1 3/4
= 5/3 ÷ 7/4
= 5/3 × 4/7
= 20/21
Therefore, 20/21 gallons of water filled the sink per minute

how do I find the value of a in 30=5a
Answer:
a = 30/5 = 6
Step-by-step explanation:
Answer:
a = 6
Step-by-step explanation:
You need to try to get "a" alone.
So, since the equation shows a is being multiplied by 5, you need to divide it by 5 to get "a" alone.
Whatever you do to one side, you must do the same to the other side.
So basically, you divide both sides by 5 to find "a"
