Why can you take the cube root of a negative number?
Answer:
you can because the real cube root of any negative real number is negative.
Step-by-step explanation:
Answer: The reason that we can't have the square (or quartic) root of a negative number is that two negatives always cancel to give a plus; so the square root of a negative number is undefined. ... The Real cube root of any negative Real number is negative.bc. a negativ number multiplied by it self 3 time result negativ too

Step-by-step explanation:
The radius of a circle is 15 m. Find its area in terms of
π.
Answer:
A = 225[tex]\pi[/tex] or A = 706.858
Step-by-step explanation:
The formula to find the area of a circle is A=[tex]\pi r^{2}[/tex], with r being the radius.
In this case, 15 is your radius, so you just replace r with 15, like so:
A=[tex]\pi 15^{2}[/tex], then simplify [tex]15^{2}[/tex]
A = [tex]225\pi[/tex]
From here you can leave the answer in its exact form, [tex]225\pi[/tex], or you can simplify it by multiplying 225 times pi. In that case, your answer would be: 706.858 (rounded to the thousanths place).
If radius of a circle is 15 m then the area of circle is 225π square units.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that radius of a circle is 15m.
We have to find the area of the circle.
The formula for area of the circle is A=πr²
Given r is 15
Substitute r=15 in the area formula.
A=π(15)²
=π×15×15
=225π
Hence, if radius of a circle is 15 m then the area of circle is 225π square units.

What is the y-intercept of x = -2?
Answer:
Slope: Undefined
Y-intercept: No y-intercept
Step-by-step explanation:
Since x=-2 is a vertical line, there is no y-intercept and the slope is undefined.
solve the equation for x , x + 4y = 0
Answer:
Step-by-step explanation:
Solving
x+4y+-4y=0+-4y _Add -4y to both sides.
x=-4y
Answer
x=4y
Answer:
1. x=-4 y=1
Step-by-step explanation:
12y=-3x
If 12y's are equal to -3x, then x must equal -4 and y=1 (well lets see if that works because I am doing this in my head rn)

What is the value of x?
Enter your answer in the box.
x =
Answer:
X = 62°
Step-by-step explanation:
Since opposite or vertical angles are equivalent, you can form the equation that 28 + x = 90 (In case you didn't know, right angles are always 90°). Subtract 28 from both sides to find the value of x and you'll get x = 90 - 28 or x = 62°.

If 8 engines consume 12000 kgs. of coal when each running 10
hours per day, how much coal is required for 7 engines out
which 5 are running 12 hours a day and the rest 6 hours a day?
Answer:
11200 for 7 engines for a total of 80 hours
Step-by-step explanation:
You have 8 engines burning 12000 .for 10 hours.
Divide 10 hours into 12000=1200 PER hour.
1200 ÷8 engines = 140 per hour per engine.
140 × # of hours (12)=1680 for 12 hours per engine.
# of engines × 1680 for 12 hour/per engine
5×1680 = 8400 of fuel for 12 hours/5 engine
Then you have 2 that runs 10 hours
2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours
8400. + 2800= 11200 of fuel for 6 engines

3/5 of 5 is 3
So that's correct.
If you still aren't sure you should try that with a different point. Hmm how about :
9 cups of almonds for 15 cups of oats
3/5 of 15 = 45/5 = 9
That's correct as well.

A school cafeteria makes 4 different salads during the week but serves only 2 each day on a rotating basis. The 4 salads are listed below.
• Chicken (C)
• Fruit (F)
• Pasta (P)
• Tuna (T)
Part A: Use the letters C, F, P, and T to list all outcomes of 2 salads.
Part B: A student randomly chooses a day to buy a cafeteria salad without knowing which 2 salads are being served. What is the probability the student chooses a day the cafeteria is serving chicken salad, pasta salad, or both? Show your work or explain your thinking.
(sorry if this is confusing, but I really needed the answer!)
Answer:
A) CF CP CT FP FT PT
B) 5/6 or ~83.3%
Step-by-step explanation:
A) Each letter combination lists the outcomes of 2 salads. Order doesn't matter so CF and FC are the same thing and do not need to be listed twice.
B) Using Part A we know that there are 6 outcomes of 2 salads. 5 out of those 6 outcomes serve chicken, pasta or both. Only the day that serves both Fruit and Tuna is there an outcome that doesn't have Chicken and/or Pasta.
What is the value of (a+b) in the system of equations below?
6(a + b) + 2z = -8
a+b+z = 2
Selett one:
A. 3
O B.-4
O C. - 3
O D.-1
Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3
