Step-by-step explanation:
BTW i'm probably wrong because my mom says i suck at math but friend me please lol
Answer: 1 19/24 ft
Step-by-step explanation: You multiply the fractions by the numbers needed to get the common denominator of 24 in this case 5/8 (put the two to the side for now.) multiply both top and bottom by 3 which will get you 15/24 then the whole number 2, your going to take it and subtract one from it so now there is only one whole number then with the one you subtracted you multiply (1x24)+15 *for the numerator* so now its 39/24 and for the second fraction 5/6 multiply both top and bottom by 4 now your fraction is 20/24 now...--> 39/24 - 20/24=19/24 and the left over whole number from the beginning goes down in front so the final answer is 1 19/24

Question 5 of 10
Solve 2x + 4 > 16.
O A. x<10
O B. x> 10
O C. x>6
O D. x< 6
Answer:
C
Step-by-step explanation:
2x +4 > 16
If you plug in 6 where the x is, and multiply 2 by 6, you get 12. Add 4 to 12 to get 16. If x is 6 it equals 16, so if x > 6 the answer will be more than 16.

Step-by-step explanation:
A line is defined by the two points lying on an infinitely long straight paths.
From the picture attached,
There are two endless paths 'l' and 'm' which contain (R, U) and (V, T), intersecting at a point S.
Therefore, line 'm' will be represented by VT or TV.
And line 'l' will be represented by RU or UR.

Differentiate y=(sinx)(3x^2) please help please !
Answer:
6xsinx + 3x²cosx
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)(g(x) , then
[tex]\frac{dy}{dx}[/tex] = f(x)g'(x) + g(x)f'(x)
Here f(x) = sinx ⇒ f'(x) = cosx
g(x) = 3x² ⇒ g'(x) = 6x
Thus
[tex]\frac{dy}{dx}[/tex] = 6xsinx + 3x²cosx
SIMPLE QUESTION, 25 PTS: The cities G, H, and I, in respective order, lie approximately in a straight line. The distance from city G to city H is 72 miles. The distance from city G to city I is 92 miles. Find the distance from city H to city I.
Hey there! I'm happy to help!
From G to I is the total distance of the line (92). G to H is the first portion of the line (72) while H to I is the other portion.
To find H to I, simply subtract 72 from 92!
92-72=20
The distance from city H to city I is 20 miles.

Rewrite one side (or both) using the distributive property
Answer:
Step-by-step explanation:
C
Rewrite one side (or both) by combining like terms which is option(C)
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
2x – 1 + 3x = 0
5x – 1 = 0
To get Equation B from A, we would rewrite one side (or both) by combining like terms
2x – 1 + 3x = 0
5x – 1 = 0
This is Equation B

Step-by-step explanation:
A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?
Volume of a cube = (edge)^3
In this problem,
Volume = 216in^2
Edge = ?
Let's plug our values into the formula above.
216in^3 = (edge)^3
Take the cbrt of both sides.
6in = edge
The length of each edge = 6in
Answer:
[tex]\boxed {\tt 6 \ centimeters}[/tex]
Step-by-step explanation:
The volume of a cube can be found using the following formula:
[tex]v=s^3[/tex]
where [tex]s[/tex] is the side length, or edge.
We know the volume is 216 cubic inches. We can substitute 216 cm³ in for [tex]v[/tex], the volume.
[tex]216 \ cm^3 = s^3[/tex]
We want to find the side length. Therefore, we must isolate the variable, [tex]s[/tex].
s is being cubed. The inverse of a cube is the cube root. Take the cube root of both sides of the equation.
[tex]\sqrt[3]{216 \ cm^3} =\sqrt[3]{s^3}[/tex]
[tex]\sqrt[3]{216 \ cm^3} =s[/tex]
[tex]6 \ cm=s[/tex]
The length of each edge of the cube is 6 centimeters.

C. 17 in.
D. 23 in.
Answer:
C. 17
Step-by-step explanation:
I'm assuming you need the hypotenuse so to get that you do
The square root of a^2 + b^2
a squared + b squared
So it becomes square root of 8^2 + 15^2
= square root of 64 + 225
= square root of 289
= 17
