Answer:
[tex]A=384\ cm^2[/tex]
Step-by-step explanation:
Let the sides of a triangle be 6x,8x and 10x.
Perimeter of the triangle, P = 96 cm
We need to find the area of the triangle.
P = sum of all sides
6x+8x+10x = 96
24x = 96
x = 4
Sides are :
6x = 6(4) = 24 cm
8x = 8(4) = 32 cm
10x = 10(4) = 40 cm
Area,
[tex]A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 24\times 32\\A=384\ cm^2[/tex]
So, the area of the triangle be [tex]384\ cm^2[/tex].

A middle school student reads 48 books in 31/3 years. Find the students reading rate in books per year
Answer: 14 2/5 books per year
Step-by-step explanation:
From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:
= Total books read / Number of years
= 48 ÷ 3 1/3
= 48 ÷ 10/3
= 48 × 3/10
= 144/10
= 14 2/5 books per year

Diego scored 9 points less than Andre in the basketball game. Noah scored twice as many points as Diego. If Noah scored 10 pints, how many points did Andre score?
Answer:
Let andre score be x points.
then Diego's score will be (x-9) points.
Noah's points=2(x-9) points
the equation is 2(x-9) = 10
dividing both sides by 2,
2(x-9)/2 =. 10/2
x-9= 5
adding 9 both sides,
x-9+9= 5+9
x=14.
Step-by-step explanation:
Answer:
Andre score 14 points
Step-by-step explanation:
noah = 2*diego
diego = andre - 9
given noah = 10
noah = 2*Diego
10 = 2*Diego
Diego = 5
diego = andre - 9
5 = andre - 9
andre = 9 + 5
Andre = 14
Given a set of data, what steps would you take to identify whether the data showed linear or exponential growth?
Answer:
See explanation
Step-by-step explanation:
The first thing to do when given a data set is to ensure that the x-values are spaced in equal intervals.
The next is now to determine if the given y-values are increasing by the same amount(a common difference) or by the same ratio(a common ratio).
The data set is linear if the y-values increase by a common difference and the data set is exponential if the y-values increase by a ratio or factor.
Answer:
Which of the following steps did you include? Check all of the boxes that apply.
Make sure that the x-values are spaced apart in equal intervals.
Determine whether the y-values increase by the same amount or by the same ratio.
Decide that the data is linear because the y-values increase by a common difference.
Decide that the data is exponential because the y-values increase by a ratio or factor.

Kathy wants to paint the faces of her standard six-sided die so that each face is either red or blue. However, she does not want all of the faces to be the same color. How many ways are there for Kathy to paint her die?
Answer:
The number of ways Kathy can paint her die is 52 ways
Step-by-step explanation:
The permutation and combination related question is answered as follows;
The number of faces in the six-sided die = 6
The number of colors available for painting the six-sided die = 2 colors
Therefore, we have, the total number of ways Kathy can paint her die, 'n', given as follows;
n = ₆P₂ + 2₄P₄ + 2₄P₃ + ₄P₂
Where;
₆P₂ = The number of ways of arranging 2 objects in 6 spaces = 30
₄P₄ = The number of ways of arranging 4 objects in 4 spaces = 1
₄P₃ = The number of ways of arranging 3 objects in 4 spaces = 4
₄P₂ = The number of ways of arranging 2 objects in 4 spaces = 12
∴ n = 30 + 2×1 + 2×4 + 12 = 52
The number of ways Kathy can paint her die, n = 52 ways.

Complete the equations so that the solution of the system of equations is (−1, −4). y= ?X−11 6x− ? Y=10
Answer:
y = –7x – 11
6x – 4y = 10
Step-by-step explanation:
From the question given above, we obtained:
x = –1
y = –4
y = ?x – 11 ....... (1)
6x – ?y = 10b......... (2)
Let the two unknown be a and b. Thus the above equation becomes:
y = ax – 11 ......... (3)
6x – by = 10 .......(4)
Next, we shall determine the value of 'a' and 'b'. This can be obtained as follow:
For a:
y = ax – 11
x = –1
y = –4
–4 = a(–1) – 11
–4 = –a – 11
Collect like terms
–4 + 11 = –a
7 = –a
Multiply through by –1
a = –7
For b:
6x – by = 10
x = –1
y = –4
6(–1) – b(–4) = 10
–6 + 4b = 10
Collect like terms
4b = 10 + 6
4b = 16
Divide both side by 4
b = 16 / 4
b = 4
Finally, we shall substitute the value of a and be into equation 3 and 4 respectively.
y = ax – 11
a = –7
y = –7x – 11
6x – by = 10
b = 4
6x – 4y = 10
Therefore, the complete equation are:
y = –7x – 11
6x – 4y = 10
Kenny wants to take his dog to obedience school. At Sit and Stay School, 12 lessons cost $96. At Canine Community Center, 25 lessons cost $125. Which is the better deal?
Answer:
25 lessons that cost $125
Step-by-step explanation:
If 8 lessons cost $96
then, 96/12 =8
therefore a lesson costs $8
If 25 lessons costs $125
then, 125/25= 5
therefore a lesson costs $5 which is cheaper.
An average person can type 2,4002,400 words per hour. Trista types at the same rate as the average person and made the double number line below to estimate how long it will take her to type her research paper. Using Trista's double number line, estimate how long it will take her to type her 1,400-word research paper.
Answer:
35 minutes
Step-by-step explanation:
Given that:
Trista:
Average word type per hour = 2400 words /hr
For Trista to type her 1400 word research paper ;
It will take 'h' hour
If
2400 words = 1 hour
1400 words = h
Cross multiply :
2400h = 1400
h = 1400 / 2400
h = 0.5833333 hr
To minutes, it will take :
0.5833333 * 60 = 35 minutes
Hence, it will take Trista 35 minutes or 0.5833333 to type her 1400 words research paper.

if y(x) = 5x-2 and g(x) = 2x + 1, find (f + g)(x).
Answer:
(f + g)(x) = 7x - 1
Step-by-step explanation:
Given : f(x) = 5x – 2 and g(x) = 2x + 1
We have to find (f + g)(x)
Consider (f + g)(x) = f(x) + g(x)
Also, given f(x) = 5x – 2 and g(x) = 2x + 1
Substitute, we have,
f(x) + g(x) = 5x - 2 + 2x + 1
LIKE TERMS are terms having same variable with same degree.
Simplify by adding like terms, we have,
f(x) + g(x) = 5x + 2x - 2 + 1
f(x) + g(x) = 7x - 1
Thus, (f + g)(x) = 7x - 1

The aquarium opened at 8.00 am . In the first hour 140 people purchased admission tickets . In the second hour 25 % more people purchased admission tickets than the first hour . Each ticket cost 15.25 . What was the total amount of money paid for all the tickets purchased in the first two hours please help
Answer:
Total income= $4,083.75
Step-by-step explanation:
First, we need to calculate the total number of people that enter the aquarium in the first two hours.
1st hour= 140
2nd hour= 140*1.25= 175
Total number of people= 315
Now, we can determine the total amount of money earned:
Each ticket cost 15.25.
Total income= 315*15.25
Total income= $4,083.75
