Answer:
Let x = the number
A negative number is 42 less than its square ⇒
x = x2 - 42
x2 - x - 42 = 0
(x - 7)(x + 6) = 0
x = 7 or -6
But since it is given that x is negative, the final answer is x = -6.
Is 3/7 and 10/21 proportional ? 15 points
Answer:
NOT proportional.
Step-by-step explanation:
Get a common denominator of 21 by multiplying 7 and 3 by 3.
[tex]\frac{3}{7}(\frac{3}{3})=\frac{9}{21}[/tex]
When both fractions have the same denominator, their numerators are different. Therefore, they are NOT proportional.

Step-by-step explanation:
If i got the points correct, (0,3) and (5,0) i couldnt tell what the other point is so i assumed it was 5.
Equation of the line: (if needed)
y = -0.6x + 3
or

The lcm of 5^3 and 5^2 is?
Answer:
5³
Step-by-step explanation:
5³ is the answer since it's the greater between the two numbers
Answer:
125
Step-by-step explanation:
This is because 5^2 *5 is 125 and 5^3 * 1 = 125 and the findings are both numbers have to be multiplied by a whole number to quantify a same identical multiple total number - we can check this by dividing by the smallest 125/5^2 = 5 and then the largest is 125/5^3 = 1 and we know there could not be a smaller whole number - The other workings would be to do a prim e factor tree of 125 = 5 25 5 and 5 = 5^3 and here we are told 5^3 is a multiple of 125 and 5^2 is also a multiple of 5^3 as it square fits 5 times into 125 as 5*25 is 125

Find the volume of the following cone.
Round your answer to one decimal place.
Answer:
429.4 cubic units
Step-by-step explanation:
Volume of a cone = pi*r^2*(h/3)
height = 9
radius = 6.75
pi*6.75^2*(9/3) = pi*45.5625*3 = 136.6875pi
136.6875*pi is around 429.416 -> rounded = 429.4
Answer:
See answer below.
Step-by-step explanation:
[tex]V = \frac{1}{3} \pi r^2h[/tex]
[tex]V = \frac{1}{3}\pi (6.75)^2(9)[/tex]
[tex]V = 3\pi (6.75)^2[/tex]

Answer:
it's 3. how could u not know that 0.4 x 3 = 1.2 duh
The value of the expression is 3.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
1.2 ÷ 0.4
= 1.2 / 0.4
The decimal point gets canceled.
= 12/4
= 3
Thus,
The value of the expression is 3.

*What is the correct value of b?
~50/100 = b/28
-b=14
-b=20
-b=10
*What is the value of n?
~25/100 = 7/n
-n=28
-n=24
-n=32
Answer:
-b = 14
-n = 28
Step-by-step explanation:
For b
50/100=b/28 cross-multiply
1400= 100b divide both sides by hundred
-b = 14
For n
25/100= 7/n cross multiply
25n = 700 divide both sides by 25

actual answer: 1.39 x 10^12
Step-by-step explanation:
If it was addition, then she’d be correct;
6.75x10^6 + 0.2x10^6
= (6.75 + 0.2)x10^6
= 6.95x10^6
But really, it was a multiplication, meaning the answer really is;
