Answer:
Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.
Step-by-step explanation:
Let
Inches = x
Feet = y
Constant of proportionality = k
ratio of feet to inches
x = ky
1 feet = 12 inches
12 = k * 1
k = 12/1
k = 12
Ratio of inches to feet.
y = kx
1 = k * 12
k = 1/12
Jada compared ratio of feet to inches while Lin compared ratio of inches to feet.

2 Which of the following is the equation of the straight line with slope of 2 and with the same y-
intercept as that of the line represented by the equation y = 4x - 2?
F
1
y = 2x +
G
1
y = 4x -
2
Hy = 4x + 2
Jy = 2x - 2
Answer:
y = 2x-2
Step-by-step explanation:
Generally, we have the equation of a straight line as;
y = mx + b
where m is the slope and b is the y-intercept
For the second equation, we can see that the y-intercept value is -2
So using the slope 2, we write the complete equation as;
y = 2x - 2

Do you knows the product of a number and four is 1.08. He says the other factor must be 2.7 because there's only one digit before the decimal point in the product 1.08, so, there must be one digit before the decimal in the factor. Is drew correct
Answer:
Drew is incorrect
Step-by-step explanation:
Drew is incorrect
Let the number be x such that if the product of the number and four is 1.08 then
x * 4 = 1.08
Divide both sides by 4
x = 1.08/4
= 0.27
Drew is incorrect because the result (1.08) has 2 decimal places and not once as deduced by him hence the number of digits before the decimal point for the numbers being multiplied must be 2.
A company receives different types of objects and typically receives 75 new objects on average each month. The company currently has 210
objects in stock, which have a variety of properties. Write
an algebraic equation that describes the relationship between the number of
additional months the company receives objects (m) and the total number of objects in the company (t).
Fill in the blank for
Answer: t= 75m+210
Step-by-step explanation:
Linear equation: y= nx+c
, where n =rate of change of y with respect to x, c= initial value of y
Let m= number of additional months the company receives objects .
t =total number of objects in the company.
Given: Number of objects received per month = 75. (Rate of change of t w.r.t. m)
Current number of objects = 210 (Initial value)
Then, t= 75m+210
Hence, the required algebraic equation: t= 75m+210

In order to determine her pulse rate, June’s nurse counted 18 beats in her pulse in 15 seconds. At this rate, how many beats would she have in 60 seconds?
In this Problem you can use the Cross Multiplication.
If in 15 seconds the nurse counted 18 beats, so in 60 seconds she will count x beats.
15 seconds = 18 beats
60 seconds = x beats
You use the cross multiplication and multiply 60 by 18 and 15 by x, so you get:
15x = 60 * 18
15x = 1080
Then, you divide 15x and 1080 by 15 each, so you get:
x = 72
So, the Nurse counted 72 beats in 60 seconds
Yourwelcome :)
Answer: 72 bmp
Step-by-step explanation: multiply by 4 because 15 goes into 60 4 times

Consider the differential equation dy/dx = xy. Let y = f(x) be the function that satisfies the differential equation with initial condition f(1) = 1. Use Euler's Method, starting at x = 1 with a step size of .1, to approximate f(1.2).
Answer:
[tex]f(1.2)=1.221[/tex]
Step-by-step explanation:
From the question we are told that
[tex]dy/dx = xy[/tex]
Initial condition[tex]f(1) = 1.[/tex]
[tex]x = 1[/tex]
[tex]Step\ Size\ of\ 0.1[/tex]
Generally equation for [tex]y_1[/tex] is given mathematically as
[tex]f_0=F(1,1)=1[/tex]
Therefore
[tex]y_1=y_0+hf_0[/tex]
[tex]y_1=y_0+(0.1)(1)[/tex]
[tex]y_1=1.1[/tex]
Generally the approximation of the solution is mathematically given by
[tex]x=1+h\\x=1+0.1\\x=1.1[/tex]
[tex]y=1.1[/tex]
Generally the [tex]f_1[/tex] is mathematically given by
[tex]F_1=f(1.1,1.1)\\F_1=1.21[/tex]
Generally the [tex]y_2[/tex] is mathematically given by
[tex]y_2=y_1+hf_1\\y_2=1.1+0.121\\y_2=1.221[/tex]
Generally the approximation to the solution
at
[tex]y_2=1.221[/tex]
[tex]x_2=1.1+0.1\\x_2=1.2[/tex]
Therefore
[tex]f(1.2)=1.221[/tex]

Tickets to a freshman basketball game are $5 for students and $8 for adults. Last week 64 tickets were sold to the game for a total of $461. How many of each ticket were sold?
Answer:
Step-by-step explanation:
Let s be number of students and a be number of adults.
a + s = 64 -> 5a + 5s = 320
8a + 5s = 461
(8a + 5s) - (5a + 5s) = 461 - 320
3a = 141
a = 47
a + s = 64 -> s + 47 = 64 -> s = 17
Please thank, rate 5, and give brainliest if helpful!
Answer:
a + s = 64 -> 5a + 5s = 320
8a + 5s = 461
(8a + 5s) - (5a + 5s) = 461 - 320
3a = 141
a = 47
a + s = 64 -> s + 47 = 64 -> s = 17

Annie decided to build a fence around her 15 ft long rectangular flowerbed. How many feet of fencing should she buy if the width of the flowerbed is 4/5 the length?
Answer:
54 ft
Step-by-step explanation:
Length of the rectangular flowerbed = 15 ft
Width of the rectangular flowerbed = 4/5 of the length
= 4/5 × 15
= (4*15)/5
= 60/5
= 12
Width of the rectangular flowerbed = 12 ft
How many feet of fencing should she buy
Perimeter of the rectangular flowerbed = 2(length + width)
= 2(15ft + 12ft)
= 2(27ft)
= 54 ft
Perimeter of the rectangular flowerbed = 54 ft
She should buy 54 ft of fencing
Identify the conclusion of the statement.
If 2n-7 > 25, then n > 16
1- 2n-7 > 25
2- n > 16
3- 2n > 32
4- no conclusion can be made
Answer:
2) n > 16
Step-by-step explanation:
Usually, a statement is written as:
If P, then Q
Where P = hypothesis
Q = conclusion.
And our statement is:
if 2n - 7 > 25, then n > 16
(We can easily solve the inequality to get the thing in the right:
2n - 7 > 25
2n > 25 + 7 = 32
n > 32/2 = 16
n > 16 )
then:
P = (2n - 7)
Q = n > 16
Then the conclusion is: n > 16
The correct option is 2) n > 16

Step 1: Define
8 = a - 2
Step 2: Solve for a
Add 2 on both sides: 10 = aRewrite: a = 10Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: 8 = 10 - 2Subtract: 8 = 8Here we see that 8 does indeed equal 8.
∴ a = 10 is the solution to the equation.
(-1) 1001 integers .solve this
Answer:
-1
Step-by-step explanation:
(-1)^1001
= (-1)^1000 * (-1)^1
Since -1 raise to the power of an even number gives a positive value, then;
(-1)^1000 = 1
(-1)^1000 * (-1)^1 = 1 * -1
(-1)^1000 * (-1)^1 = -1
Hence (-1)^1001 = -1
-⅔ (6x +9) = 18 I really need some help and understanding with this one. Thanks in advance!!
-⅔ (6x + 9) = 18
Apply distributive property. Multipy -⅔ to 6x and 9.
-4x - 6 = 18
Add 6 to both sides so -4x can be alone.
-4x - 6 + 6 = 18 + 6
-4x = 24
To get x alone, divide both sides by -4.
-4/-4x = 24/-4
x = -6
x = -6 is your answer. I hope this helps! Let me know if you need more help or if I got something wrong.

f is inversely proportional to √ g . When f = 8 , g = 25 Work out f when g = 16
Answer:
f = 10
Step-by-step explanation:
find out the constant of variation 'k': F = k/[tex]\sqrt{g}[/tex]
8 = k/ [tex]\sqrt{25}[/tex]
k = 8 · 5
k = 40
f = 40/[tex]\sqrt{16}[/tex]
f = 40/4
f = 10
