Answer:

6.4 oz are left.

Step-by-step explanation:

Start with the bottle being half full.

A bottle that is half full when it started with 16 oz is 1/2 16 oz = 8 oz

If he drinks 1/5 of the remaining amount, it means that he has 4/5 left.

4/5 * 8 = 32/5 = 6.4 oz or 6 oz and 2/5 of an ounce.

Answer:

[tex]\frac{9}{16}[/tex] cups of raisins are in each serving

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity as 1 such as 2 meter per seconds or 4 miles per hour.

As per the statement:

The bake star bakery uses 2 1/4 cups of raisins to make 4 servings of trail mix.

⇒Cup of raisins = [tex]2\frac{1}{4} = \frac{9}{4}[/tex] and number of serving  = 4

We have to find the cups of raisins are in each serving

Then by definition of unit rate we have;

[tex]\text{unit rate per serving} = \frac{\frac{9}{4} }{4} = \frac{9}{16}[/tex] cups of raisins

therefore, [tex]\frac{9}{16}[/tex] cups of raisins are in each serving

[tex]v = u + 5t\\\\5t=v-u\\\\t=\dfrac{v-u}{5}[/tex]

To make t the subject of the formula v = u + 5t, subtract u from both sides and divide by 5.

To make t the subject of the formula v = u + 5t, we need to isolate t on one side of the equation.

First, subtract u from both sides of the equation: v - u = 5t.

Then, divide both sides of the equation by 5: (v - u)/5 = t.

Answer:

11.00

Step-by-step explanation:

To calculate the interquartile range of the data:

5, 5, 6, 7, 9, 11, 14, 17, 21, 23

To calculate the interquartile range we need to lower quartile [tex](X_L)[/tex] and upper quartile [tex](U_L)[/tex].

The lower interquartile [tex](X_L)[/tex] of the data set is: 6.

The upperquartile [tex](U_L)[/tex] of the data set is: 17.

Therefore, the interquartile range is:  [tex](X_U-X_L)=(17-6)=11[/tex].

Step-by-step explanation:

[tex]\sqrt[3]{343x^9v^{12}z^6}=\sqrt[3]{343}\cdot\sqrt[3]{x^{3\cdot3}}\cdot\sqrt[3]{v^{4\cdot3}}\cdot\sqrt[3]{z^{2\cdot3}}\\\\=\sqrt[3]{7^3}\cdot\sqrt[3]{(x^3)^3}\cdot\sqrt[3]{(v^4)^3}\cdot\sqrt[3]{(z^2)^3}=7x^3v^4z^2\\\\Used:\\\\\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\(a^n)^m=a^{nm}\\\\\sqrt[n]{a^n}=a[/tex]

The cube root of 343 is 7, x^9 is x^3, v^12 is v^4, and z^6 is z^2. So the equivalent expression to the cube root of [tex]343x^9v^12z^6[/tex] is 7x^3v^4z^2.

The expression is asking for the cube root of each term. The cube root of 343 is 7 because [tex]7*7*7[/tex]equals to 343. The cube root of x^9 is x^3 because 3*3 equals to 9. Similarly, cube root of v^12 is v^4 because 4*3 equals 12, and cube root of z^6 is z^2 because 2*3 equals 6.

So the equivalent expression is [tex]7x^3v^4z^2.[/tex]

Remember, when dealing with cubic roots and exponential terms, we divide the exponent by 3.

Hi!

Equation: Y = P% * X

X = Y/P%

To determine the size of the home video collection one can save, subtract the used space (122 GB) from the total hard drive capacity (160 GB). The remaining space is 38 GB, which is the maximum size for the home videos that can be saved. The inequality representing the available space in terms of 'a' is: a ≤ 38 GB.

The subject of this question is a practical application of mathematics related to computer storage space.

If the computer's hard drive has a total capacity of 160 GB and you have already used 122 GB, we can determine the remaining available space with a simple subtraction: 160 GB - 122 GB = 38 GB.

So, the size of the home video collection that you can save cannot exceed 38 GB.

To represent this as an inequality where u is the amount used, and a is the amount available, we can write:

u + a ≤ 160 GB

Since you've used 122 GB already, the inequality in terms of a alone is:

a ≤ 160 GB - 122 GB

a ≤ 38 GB

This inequality states that the amount of additional data (home videos) you can save, denoted as a, should be less than or equal to 38 GB, which is the available space remaining on your hard drive.

Final answer:

To determine the available space on your hard drive, subtract the amount used from the total capacity. The possible sizes of the home video collection you can save range from 0GB to a maximum of 38GB. The inequality a ≤ 38GB represents the amount of space available.

Explanation:

To determine the amount of space available, you subtract the amount of space used from the total capacity. In this case, the total capacity is 160GB and the amount used is 122GB, so the amount of space available is 160GB - 122GB = 38GB.

Therefore, the possible sizes of the home video collection you can save range from 0GB (if you don't save any videos) up to a maximum of 38GB (if you save videos that take up the entire available space).

The inequality that represents this is: a ≤ 38GB, where 'a' represents the amount of space available.

5 . x ÷ 7 = 10 or less

5 . 14 = 70 ÷ 7 = 10

The unknown number, when multiplied by five and divided by seven, has to result in a value of 10 or less. To find this number, we solve the inequality 5x / 7 <= 10 and find that x must be less than or equal to 14.

The question is asking for a number that, when multiplied by five and then divided by seven, yields a result of 10 or less. Let's denote the unknown number as x. We can put this into a mathematical inequality:

5x / 7 <= 10

To solve for x, we first multiply both sides by 7 to cancel the denominator on the left side:

5x <= 70

Then, we divide both sides by 5 to isolate x:

x <= 14

Therefore, the number must be less than or equal to 14.

Answer:

15/100

0.15 is 15 hundredths, which can also be written as 15/100. If you say the decimal out loud, and then the fraction out loud, you say them the same.

Remark

There are a couple of ways to do this. The easiest is to take the number of degrees between 42 and - 54 and divide by 12.

Method

the number of degrees is abs(42) + abs(-54) = 42 + 54 = 96

Now divide by 12

Hours = 96 / 12 = 8 hours. I think the answer is A.

Answer:

Step-by-step explanation:

Sales tax paid by Donte = [tex]\frac{5.6}{100} (5)[/tex]

= 0.28

Sales tax paid by Trista = [tex]\frac{7}{100} (5)[/tex]

= 0.35

The extra tax paid by Trista = 0.35 - 0.28 = 0.07.

Hence, Trista paid $0.07 more than Donte.

To calculate the total amount Aleta spent, including the tip, multiply the bill ($36) by the tip percentage (15%) to get the tip amount ($5.40) and add it to the bill to get the total cost ($41.40).

The question asks us to calculate the total amount Aleta spent on dinner including a 15% tip. To find the tip amount, we multiply the bill by the tip percentage in decimal form. The bill is $36, so we calculate 15% of $36 as follows:

0.15 × $36 = $5.40

The total cost of the meal including the tip is $36 (the original bill) + $5.40 (the tip) = $41.40.

Hey there!!

What is slope-intercept form ?

Ans :- y = mx + b

Where ' m ' is the slope and ' b ' is the y-intercept.

Equation given :- y = kx + 2

Now, we know k is m or the slope and 2 y-intercept.

y-intercept can be given as a coordinate.

Hence, y - intercept 2 can be written as ( 0 , 2 )

Now we have 2 coordinates, ( 0 , 2 ) and ( -7 , 12 )

How do we find slopes ?

Ans :- Slope = [tex]\frac{y2- y1 }{x2-x1}[/tex]

Plugging in the values :

Slope = [tex]\frac{12-2}{-7-0}[/tex]

Slope = [tex]\frac{-10}{7}[/tex]

Hence, the value of 'k' is [tex]\frac{-10}{7}[/tex]

Hope my answer helps!

Answer:

k = -10/7

Step-by-step explanation:

1. Plug in (x,y)

2. You would get -7k+2=12
