Answer:
Recognize that both 0.96 and 0.144 are divisible by 12:
(0.96/12) / (0.144/12) = 0.08 / 0.012. This reduces to 0.02 / 0.003, or
20/3 or approx. 6.666.
You could also begin by eliminating the decimal fractions. Mult. 0.96 and 0.144 each by 1000 results in 960/144.
Since both 960 and 144 can be divided evenly by 24, we get 40 and 6.
40/6 = 20/3, or approx. 6.666, as before.

A publisher estimates their costs of publishing a book is from $980,000 to $1,240,000. So far, they have spent $824,000. Which compound inequality correctly expresses how much more the publisher can spend?
$155,850 ≥ x ≤ $415,850
$155,850 ≤ x ≥ $415,850
$155,850 ≥ x ≥ $415,850
$155,850 ≤ x ≤ $415,850
Answer:
[tex]155,850 \leq x \leq 415,850[/tex]
Step-by-step explanation:
A publisher estimates their costs of publishing a book is from $980,000 to $1,240,000.
Let x be the amount publisher can spend
So, [tex]980000\leq x \leq 1240000[/tex]
Now we are given that So far, they have spent $824,000
So, [tex](980000-824000)\leq x \leq (1240000-824000)[/tex]
[tex]156000\leq x \leq 416000[/tex]
So, Option D is true
Hence compound inequality correctly expresses how much more the publisher can spend is [tex]155,850 \leq x \leq 415,850[/tex]

Car X leaves Northtown traveling at a steady rate of 55 mph. Car Y leaves 1 hour later following Car X, traveling at a steady rate of 60 mph. Which equation can be used to determine how long after Car X leaves Car Y will catch up?
The equation that can be used to determine how long after Car X leaves Car Y will catch up is D. 55x = 60(x - 1).
To determine when Car Y will catch up to Car X, we need to find the time it takes for Car Y to cover the same distance as Car X. Since Car Y leaves 1 hour later, it will travel for (x - 1) hours, where x represents the time Car X has been traveling. So, the equation would be:
D. 55x = 60(x - 1)
This equation accounts for the distance traveled by both cars over the same time frame, considering Car Y started an hour later.
Complete question : Car X leaves Northtown traveling at a steady rate of 55 mph. Car Y leaves 1 hour later following Car X, traveling at a steady rate of 60 mph.

Gio is solving the quadratic equation by completing the square 5x^2+15x-4=0 What's should gio do first?
Gio should first complete the square by adding and subtracting [tex]\((\frac{3}{2})^2\)[/tex], leading to the equation [tex]\((x + \frac{3}{2})^2 = \frac{25}{4}\).[/tex]
To solve the quadratic equation [tex]\(5x^2 + 15x - 4 = 0\)[/tex] by completing the square, Gio should follow these steps:
1. Make the Coefficient of [tex]\(x^2\) 1:[/tex]
Divide the entire equation by the coefficient of [tex]\(x^2\)[/tex] to make it equal to 1. In this case, divide the equation by 5:
[tex]\[x^2 + 3x - \frac{4}{5} = 0.\][/tex]
2. Move the Constant to the Other Side:
Move the constant term to the other side of the equation:
[tex]\[x^2 + 3x = \frac{4}{5}.\][/tex]
3. Complete the Square:
Add and subtract [tex]\((\frac{3}{2})^2\)[/tex] inside the parentheses to complete the square:
[tex]\[x^2 + 3x + (\frac{3}{2})^2 = \frac{4}{5} + (\frac{3}{2})^2.\][/tex]
4. Factor the Perfect Square Trinomial:
Factor the left side, which now is a perfect square trinomial:
[tex]\[(x + \frac{3}{2})^2 = \frac{25}{4}.\][/tex]
5. Solve for (x):
Take the square root of both sides and solve for (x):
[tex]\[x + \frac{3}{2} = \pm \frac{5}{2}.\][/tex]
6. Isolate (x):
Isolate (x) on one side to find the solutions:
[tex]\[x = -\frac{3}{2} \pm \frac{5}{2}.\][/tex]
Therefore, Gio should first complete the square by adding and subtracting [tex]\((\frac{3}{2})^2\)[/tex], leading to the equation [tex]\((x + \frac{3}{2})^2 = \frac{25}{4}\).[/tex]

write an expression 13+ 19+ 17 using mental math
Explanation:
It is convenient to regroup the numbers, and adjust two of them to "make a ten".
= 13 + 17 + 19 . . . . rearrange (swap the order of 17 and 19)
= (10 + 3) + (-3 + 20) + 19 . . . . "make a ten" by adding or subtracting a small number. Here, those adjustments cancel—which is the point of doing it.
= 10 + 20 + 19
= 30 + 19

The cost of renting a car is $35/wk plus $0.25/mi traveled during that week. An equation to represent the cost would be y = 35 + 0.25x, where x is the number of miles traveled. If your cost was $51.25, how many miles were you charged for traveling?
To find the number of miles traveled when the total cost is $51.25, subtract the base cost from the total and divide by the per-mile rate, resulting in 65 miles traveled.
Explanation:The question asks how many miles were traveled if the total cost for renting a car was $51.25. According to the equation y = 35 + 0.25x, where y represents the total cost and x represents the miles traveled, we first need to subtract the base cost of $35 from the total cost to find out how much is charged for the mileage.
Here is how you calculate it:
Subtract the weekly rental cost from the total cost: $51.25 - $35 = $16.25. Divide the remaining cost by the cost per mile: $16.25 / $0.25 = 65 miles.
Therefore, you were charged for traveling 65 miles.

Solve 11kx + 13kx = 6 for x.
A. X= 1/4k
B. X= 4k
C. X= 4/k
D. X= k/4
Answer:
Option (a) is correct.
[tex]x=\frac{1}{4k}[/tex]
Step-by-step explanation:
Given: Equation 11kx + 13kx = 6
We have to solve for x and choose the correct option from the given options.
Consider the given equation 11kx + 13kx = 6
Taking kx common, we have,
kx (11+13) = 6
Simplify, we have,
24kx = 6
Divide both side by 24, we have,
[tex]kx=\frac{6}{24}[/tex]
Simplify, we have,
[tex]kx=\frac{1}{4}[/tex]
Divide both side by k, we have,
[tex]x=\frac{1}{4k}[/tex]
Thus, Option (a) is correct.
Margaret uses 1 3/4 teaspoons of vanilla to make 12 cupcakes. She to wants make 30 cupcakes. how much vanilla will Margaret use?
To make 30 cupcakes Margaret needs 4.375 cups of vanilla.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
Margaret uses 1 3/4 teaspoon of vanilla to make 12 cupcakes
So,
1 3/4 teaspoon vanilla ⇒ 12 cupcakes
(4×1 + 3)/4 teaspoon ⇒ 12 cupcakes
7/4 teaspoon vanilla ⇒ 12 cupcakes
Divide by 12 into both sides,
7/(4×12) teaspoon vanilla ⇒ 1 cupcake
Now multiply by 30 on both sides,
(7 × 30)/(4 × 12)teaspoon vanilla ⇒ 30 cupcake
30 cupcakes ⇒ 4.375 teaspoon vanilla.
Hence "To make 30 cupcakes Margaret needs 4.375 cups of vanilla".
