Answer:
Step-by-step explanation:
3/5 = 0.6
1 - 0.6 = 0.4 students left
Multiply the amount of students remaining by the fractional amount that take German
0.4 x 1/4 = 0.1
1 - 0.6 - 0.1 = 0.3
0.3 x 100 = 30%
Therefore 30% of students take French

Harold cut 1812 inches off a rope that was 60 inches long. How is the length of the remaining rope in inches written in decimal form
Answer:
0.42
Step-by-step explanation:
The computation of the length of the remaining rope in inches is shown below:
Length Remaining = Length - the piece he cut off
Length Remaining = 60 - 18
60 - 18 = 42
To turn 42 into a decimal, you have to divide by 100 ↓
42 ÷ 100 = 0.42
The length of rope remaining is 0.42 inches long

Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.
Answer:
x ≈ 9.5 , y ≈ 15.3
Step-by-step explanation:
sin32° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{18}[/tex] ( multiply both sides by 18 )
18 × sin32° = x , then
x ≈ 9.5 ( to the nearest tenth )
cos32° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{18}[/tex] ( multiply both sides by 18 )
18 × cos32° = y , then
y ≈ 15.3 ( to the nearest tenth )

Answer:
3x and 8x
Step-by-step explanation:
They both share the same variable unlike 8 and 3y which have different variables. Once simplified, the expression should equal 11x + 8 + 3y
Answer:
3x and 8x
You see 3x and 8x are both like terms because they both have x
but..
The other 3 does not have a x it has a y

Make r the subject - picture underneath
Answer:
The answer is r = 6a / (5m² - 1).
Step-by-step explanation:
The steps are :
[tex]m = \sqrt{ \frac{6a + r}{5r} } [/tex]
[tex] {m}^{2} = \frac{6a + r}{5r} [/tex]
[tex]5r {m}^{2} = 6a + r[/tex]
[tex]5r {m}^{2} - r = 6a[/tex]
[tex]r(5 {m}^{2} - 1) = 6a[/tex]
[tex]r = \frac{6a}{5 {m}^{2} - 1 } [/tex]
Answer:
r = [tex]\frac{6a}{5m^2-1}[/tex]
Step-by-step explanation:
Given
m = [tex]\sqrt{\frac{6a+r}{5r} }[/tex] ( square both sides )
m² = [tex]\frac{6a+r}{5r}[/tex] ( multiply both sides by 5r )
5rm² = 6a + r ( subtract r from both sides )
5rm² - r = 6a ← factor out r from each term on the left side
r(5m² - 1) = 6a ← divide both sides by (5m² - 1)
r = [tex]\frac{6a}{5m^2-1}[/tex]
Find the answer to this question
Answer: B
Step-by-step explanation:
does anyone know the answer??
Answer:
rational
Step-by-step explanation:
Any rational number can be expressed in the form
[tex]\frac{a}{b}[/tex] ← where a and b are integers
Given
[tex]\sqrt{4}[/tex] = - 2 or + 2
Since - 2 = [tex]\frac{-2}{1}[/tex] and 2 = [tex]\frac{2}{1}[/tex] ← both in rational form, then
[tex]\sqrt{4}[/tex] is rational

A shelf is 36 inches long. How many DVD’s can I place on it if each one is 5/8 inches thick?
You can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick. To determine the number of DVDs that can fit on a shelf, we need to divide the length of the shelf by the thickness of each DVD.
The shelf is 36 inches long, and each DVD is 5/8 inches thick.
Dividing the length of the shelf by the thickness of each DVD:
36 inches / (5/8) inches
To divide by a fraction, we multiply by its reciprocal:
36 inches * (8/5 inches)
Simplifying the multiplication:
288 inches / 5 inches
Now we can divide:
288 inches / 5 inches = 57.6
Therefore, you can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick.
