Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?"
Answer:
My age is 13
My brother's age is x+3= 13+3 = 16
My sister's age is x-2=13-2=11
My mother's age is 3(x+3)-1=3(13+3)-1=47
Look at image shown simplify expression and write answer without negative exponents please
Answer:
The expression without a negative exponent will be:
[tex]\frac{8x^{-4}y^{-8}}{-2xy^5}=-\frac{4}{x^5y^{13}}[/tex]
Step-by-step explanation:
Given the function
[tex]\frac{8x^{-4}\:y^{-8}}{-2xy^5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{-b}=-\frac{a}{b}[/tex]
[tex]\frac{8x^{-4}\:y^{-8}}{-2xy^5}=-\frac{8x^{-4}y^{-8}}{2xy^5}\\[/tex]
[tex]\mathrm{Divide\:the\:numbers:}\:\frac{8}{2}=4[/tex]
[tex]=-\frac{4x^{-4}y^{-8}}{xy^5}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=\frac{1}{x^{b-a}}[/tex]
[tex]=-\frac{4y^{-8}}{x^5y^5}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=\frac{1}{x^{b-a}}[/tex]
i.e. [tex]\frac{y^{-8}}{y^5}=\frac{1}{y^{5-\left(-8\right)}}[/tex]
so the expression becomes
[tex]\frac{8x^{-4}\:y^{-8}}{-2xy^5}=-\frac{4}{x^5y^{5-\left(-8\right)}}[/tex]
[tex]=-\frac{4}{x^5y^{13}}[/tex]
Therefore, the expression without a negative exponent will be:
[tex]\frac{8x^{-4}y^{-8}}{-2xy^5}=-\frac{4}{x^5y^{13}}[/tex]

If the random variable, X, has a Poisson distribution with a mean of 4 events per minute, the mean number of events per hour is:__________.
Answer:
240 events
Step-by-step explanation:
Given that:
Mean = 4 events per minute
The mean number of events per hour :
Number of Events per minute * (number of minutes per hour)
Number of minutes per hour = 60
Hence, mean number of events per hour :
4 * 60 = 240
Krystal is comparing two Internet service plans. Plan 1 costs $34.99 per month. Plan 2 costs $134.97 every 3 months. If Krystal plans to stay with one service for 1 year, which should she choose? How much will she save?
mark as brainlist pls, answer:
She should choose plan 1 because it is cheaper even in the long run.
plan 1: 34.99 x 12 = 419.88
plan 2: 134.97 x 4 = 539.88
-
419.88 < 539.88
Answer:
Work shown below!
Step-by-step explanation:
1 year = 12 months
Plan 1 = $34.99 per month
Plan 2 = $134.97 per 3 months
Plan 1: $34.99(12) = $419.88
Plan 2: $134.97(4) = $539.88
She would save $120 if she chooses Plan 1

the 6th term of a GP is 2000. Find its first term if it's common ratio is 10
so ar^ = 2000 and you told me r = 10
a(10^5) = 2000
a = 2000/100000 = 1/50
the 6th term of a GP is 2000 is 0.02 then the first term of GP is 0.02
What is a GP(Geometric Progression)?A geometric progression, also known as a geometric sequence, is a non-zero number sequence in which each term after the first is found by multiplying the previous one by a fixed, non-zero number known as the common ratio.
Geometric Progression (GP) is a type of sequence in which each succeeding term is produced by multiplying the previous term by a fixed number known as a common ratio. This progression is also known as a pattern-following geometric sequence of numbers.
Therefore,
The general form of a GP is a, ar, ar², ar³,...., arⁿ where a is the first term and r is the common ratio.
Given r=10
6th term of a GP = 2000
We know that nth term of a GP = [tex]ar^{n-1}[/tex]
[tex]ar^5[/tex] = 2000
a × ([tex]10^5[/tex]) = 2000
a = 2000/100000
a = 1/50 = 0.02
Therefore, the first term of GP is 0.02

Write an equation in Standard Form. A store sells t-shirts for $12 each and
sweatshirts for $15 each. You plan to spend $120 on t-shirts and sweatshirts.
Answer:
12x + 15y = 120
Step-by-step explanation:
x= t shirts
y= sweatshirts
x+y=total
12x + 15y = 120
(I got this question on a quiz and I got it right!)
I hope this helps!
The equation 12x + 15y = 120 represents the total number of t-shirts and sweatshirts bought if spend $120
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The price for t-shirts = $12 each
The price for the sweatshirt = $15 each
Let's suppose x number of t-shirts and y number of sweatshirts bought.
Then,
12x + 15y = 120
The equation represents the total number of t-shirts and sweatshirts bought if spend $120
Thus, the equation 12x + 15y = 120 represents the total number of t-shirts and sweatshirts bought if spend $120

julie opens a bank account with $500.she deposits $60 each month.write a function that represents the amount that is in julies account after x months
Answer:
[tex]f(x) = 500 + 60x[/tex]
Step-by-step explanation:
Given
[tex]Ope\ ning\ Balance = 500[/tex]
[tex]Deposits = 60[/tex] --- monthly
Required
Write as a function
Represent the number of months with x and the balance at any month with f(x)
f(x) is calculated as thus:
Opening Balance + Deposits * Number of Months
So, we have:
[tex]f(x) = 500 + 60 * x[/tex]
[tex]f(x) = 500 + 60x[/tex]
Hence, the function that represents the scenario is
[tex]f(x) = 500 + 60x[/tex]

Answer: AD = 9cm
Step-by-step explanation: This is a 30-60-90 triangle, so the hypotenuse is equal to twice the length of the short side of the right angle.
BC is the short side of the large triangle, so AB, the hypotenuse of the large triangle is 2×6, 12 cm
BC is also the hypotenuse of the small triangle, ΔBCD, so it is twice the length of BD, to that makes BD = 6/2= 3
Subtract BD from AB.
That's 12 - 3 = 9 the length of AD
Allison’s cupcake and cookie budget for her party is $105. She would like to have at least 40 cupcakes and cookies combined, and would like to have at most 5 more cupcakes than cookies. If cupcakes sell for $2.50 and cookies for $1.50, which system of inequalities could help Allison determine possible numbers of cupcakes (a) and cookies (b) that she should buy? ( a ≥ 0 , b ≥ 0 )
Answer:
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Step-by-step explanation:
We are told she would like to have at least 40 cupcakes and cookies combined.
If a is number of cupcakes and b is number of cookies, then this inequality is;
a + b ≥ 40
Secondly, we are told she would like to have at most 5 more cupcakes than cookies.
Thus, the inequality is;
a + 5 ≤ b
Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50
Thus, the inequality is;
2.50a + 1.50b ≤ 105
Finally, the 3 inequalities are;
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Shade the model to show the decimal 0.674 with 100 blocks. Please help!!
Answer:
0.674 means that it 674/1000
Step-by-step explanation:
which mean that if the model consist of 1000 squares, you have to shade 674 of the squares.
If the model consist of 100 squares, you have to shade 337 of the squares ( you get the number after dividing both 674 and 1000 with 2)
