Answer:
24/5 or 4.8
Step-by-step explanation:
This would be 6/10 multiplied by 8 making it 48/10 and if you simplify that you will get 24/5.
Answer:
4.8
Step-by-step explanation:
6 tenths can be written like this: 0.6
If you were to pretend the 0.6 was a six..
6*8=48
There actually is a decimal point and you must move it back to the left one place because there was one before the six

Solve for t. Express your answer in simplest and exact form.
[tex]z=q_{1}t+t\frac{1}{2}ht^{2}[/tex]
Answer:
t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))
Step-by-step explanation:
Solve for t:
z = (h t^2)/2 + t q_1
z = (h t^2)/2 + t q_1 is equivalent to (h t^2)/2 + t q_1 = z:
(h t^2)/2 + t q_1 = z
Divide both sides by h/2:
t^2 + (2 t q_1)/h = (2 z)/h
Add q_1^2/h^2 to both sides:
t^2 + (2 t q_1)/h + q_1^2/h^2 = (2 z)/h + q_1^2/h^2
Write the left hand side as a square:
(t + q_1/h)^2 = (2 z)/h + q_1^2/h^2
Take the square root of both sides:
t + q_1/h = sqrt((2 z)/h + q_1^2/h^2) or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)
Subtract q_1/h from both sides:
t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t + q_1/h = -sqrt((2 z)/h + q_1^2/h^2)
Subtract q_1/h from both sides:
Answer: t = sqrt((2 z)/h + ((q_1)^2)/(h^2)) - q_1/h or t = -q_1/h - sqrt((2 z)/h + ((q_1)^2)/(h^2))
Pls help I’ll give you 35 points The depths of the
world's deepest oceans
and seas in feet) are:
12,880; 8,685; 13,002;
13,215; 5,468.
What is the median
depth?
Answer:
12,880
Step-by-step explanation:
You put them in least to greatest and then take one off each end, like the smallest and largest go first(5,468 and 13,215). The median is the one left in the middle and there can be more than one, but in this case there is only one and it is 12,880.

−3/5−4/5=
Answer:
-7/5.
Step-by-step explanation:
Leave the denominators the same and subtract only the numerators. Since -3 is negative and 4 is a positive being subtracted, you get -7 as the numerator. So, it's -7/5.
What is the value of f(6)
Answer:
f(6) = 35
Step-by-step explanation:
f(6) means the function value for the x-coordinate 6. To find this, we need to find out which function to use (either 0 or 35x-175). 0≤x≤5 means that f(x)=0 for any value between 0 and 5 and including 0 and 5 themselves. However, we need to find the value for x=6, so we need to use the other function (35x-175). This gives us:
f(6) = 35 * 6 - 175 = 210 - 175 = 35

find three consecutive even intergers such that the sum of the smallest number and twice the middle number is 20 more than the largest number
Answer:
10, 12, 14
Step-by-step explanation:
Hi there!
Let x be equal to the smallest integer.
Let (x+2) be equal to the next even integer.
Let (x+4) be equal to the largest even integer out of the three.
We're given:
⇒ smallest number + (2 × middle number) = 20 + largest number
Construct an equation:
[tex]x+2(x+2)=20+(x+4)[/tex]
Combine like terms:
[tex]x+2x+4=20+x+4\\3x+4=x+24\\2x=20\\x=10[/tex]
Therefore, the smallest integer is 10, making the next two even integers 12 and 14.
I hope this helps!

X+ 5 If m(x) = X-1 and n(x) = x - 3, which function has the same domain as (m×n(x)?
Answer:
Lets start off by clearing up the question,
I'm assuming it's asking m(x) * n(x). Doing so will make you foil it, giving you a quadratic/ polynomial.
Because it is a polynomial, we can assume all real numbers are defined. So really any poly works.
Edit: To clarify, you can make any quadratic equation and it will have the same domain as any polynomial is defined. So for example: x^2 + 2x + 5 works.

Find the distance in units between 1 1/2 and −2 5/6 on a number line.
Answer:
4 1/3
Step-by-step explanation:
Hypothetically, imagine 2 5/6 was postive, you add it to 1 1/2 to get your answer, but you cant do that until the fractions have a common denominator. To get a common denominator of six, you would multiply both the numerator and denominator of 1/2 by 3, giving you 3/6. Now you have 2 5/6 and 1 3/6, adding them together gives you 3 8/6, but we cant stop here, since 8/6 is 1 2/6, add 3+1 and you now have 4 2/6. The last thing you do here is simplyfy the fraction making it 1/3 now instead of 2/6. Giving you a final answer of 4 1/3 units.

im confused on the bottom circle answer its a bit weird it reads "a. (use algebra) Use the diagram at the right. What algebraic expression represents GK?
b. if GK = 30, what are GH and JK?"
Step-by-step explanation:
well you need to add the right expressions for the shorter lines so that there is no overlap. otherwise GK would be too long.
so, how can we combine the 3 red lines to get exactly GK ?
we cannot just add 2 of these lines. the results would always be either too long or too short.
but we see "2x + 3" overlaps a bit with "4x - 3". and hey, the third line "x" is just the length of the overlap of the other 2 lines.
so, we can add the first 2 lines, IF we reduce first one of them by the overlap length.
I picked the second line.
so, we have
2x + 3 - x + 4x - 3 = GK
5x = GK
so, "5x" is the algebraic expression representing GK.
now, if GK = 30, then we know
5x = 30
x = 6
GH = 2x + 3 - x (again, we need to shorten that line by the overlap length to count only to H)
= 2×6 + 3 - 6 = 6 + 3 = 9
JK = GK - GJ = 30 - (2x + 3) (here we need the full line, as we are dealing with J)
= 30 - 2×6 - 3 = 15

Answer:
Step-by-step explanation:
Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that
(x+2)+(x+2)+(2x+3)+(2x+3)=46
Combine like terms to get: 6x+10=46
Subtract 10 from both sides to get: 6x=36
Divide both sides by 6 to get: x=6.
