Answer: Lily is Correct.
Step-by-step explanation:
Lily is correct because the product of 15x52 is 15 times bigger than 15, therefore making a product (way larger) than 15. Lily is correct. Tell me if this helped or didn't help, but I hope it did (: !
0= 27x^3 + 125
Please help quickly
Answer:
-5/3 = x
x = 5/6 ± 5 sqrt(3)i /(6)
Step-by-step explanation:
0= 27x^3 + 125
Subtract 125 from each side
-125 = 27 x^3
Divide each side by 27
-125/27 = x^3
Take the cube root of each side
(-125/27 ) ^ (1/3) = x^3 ^ (1/3)
-5/3 = x
This is the only real answer
Let me know if you want the complex solutions
0= 27x^3 + 125 = ( 3x) ^3 + 5^3
a^3 + b^3 = (a+b) • (a^2-ab+b^2)
0 = ( 3x+5) ( 9x^2 - 15x +25)
Using the zero product property
3x+5 =0 9x^2 - 15x +25 =0
3x = -5 9x^2 -15x = -25
x = -5/3 9(x^2 - 5/3x) = -25
Completing the square
(x^2 - 5/3x) = -25/9
x^2 - 5/3x +25/36 = -25/9 + 25/36
( x-5/6) ^2 = -25/12
Take the square root of each side
sqrt( x-5/6) ^2 =± sqrt(-25/12)
( x-5/6) =± 5i/(2 sqrt(3))
Add 5/6
x = 5/6 ± 5i/(2 sqrt(3))
We cannot leave a sqrt in the denominator so multiply by sqrt(3)/sqrt(3)
x = 5/6 ± 5 sqrt(3)i /(2(3))
x = 5/6 ± 5 sqrt(3)i /(6)

Mr. Smith has an online cooking show. Before he films an episode about baking the perfect pound cake, he prepares his ingredients. His recipe calls for 2 1 2 cups of sugar for the cake and 1 1 4 cups of sugar for the vanilla glaze. How many 1 4 -cup scoops of sugar does he need?
Answer:
15
Step-by-step explanation:
There are 4/4 to make a whole so 2 1/2 cups would be 10 'scoops' and 1 1/4 would be 5 'scoops'. Add 10 + 5 to get a total of 15 scoops.
Hope that helps and have a great day!
Which number would complete the equivalent fraction? 4/5 = /80 64, 80, 4 or 320
Answer:
64/80
Step-by-step explanation:
When you put in your calculator 4/5 it spits out ".8".
You are looking for another fraction that spits out 0.8.
One of the choices that gets my attention is 64. Let's test it to see if I was right first try.
Calculator: 64/80 = 0.8; 64/80 is equivalent to 4/5.

The office manager of First Tech Support borrowed $25,000 to purchase new computers for employees. The bank charges 6 percent interest for 4 years. How much interest will the company pay in all?
Given:
Amount borrowed (P)= $25000
Rate of interest (r)= 6%
Time (t)= 4 years.
To find:
The total interest the company pay in all.
Solution:
We know that,
[tex]A=P(1+r)^t[/tex]
where, A is amount, P is principal, r is rate of interest and t is time period.
[tex]A=25000(1+\dfrac{6}{100})^4[/tex]
[tex]A=25000(1.06)^4[/tex]
[tex]A=25000(1.26247696)[/tex]
[tex]A=31561.924 [/tex]
Now,
[tex]I=A-P[/tex]
[tex]I=31561.924-25000[/tex]
[tex]I=6561.924[/tex]
Therefore, the total interest is $6561.924.
Answer: $6,000
Step-by-step explanation:
Most English-speaking countries use the short-scale naming system, in which a trillion is expressed as 1,000,000,000,000. Some other countries use the long-scale naming system, in which a trillion is expressed as 1,000,000,000,000,000,000,000. Express each number as a single-digit integer times a power of ten. How many times greater is the long-scale naming system than the short-scale?
Answer:
Short Scale 10^12 Long Scale 10^18
Step-by-step explanation:
Long Scale and Long Scale are bizzare. As stated most English-speaking countries use the Short Scale. This means we always have to check where the number is coming from. In the long scale, billion means one million million (10^12) and trillion means one million billions (10^18), and so on.
Answer:
1*10^12 and 1*10^21
Step-by-step explanation:
The long scale naming system is 10^9 greater than the short scale system.

Replace * with a monomial so that the trinomial may be represented by a square of a binomial:
6.25a^2+ * + 1/4b^2
Answer:
Since:
a^2-2ab+b^2 = (a-b)^2
and
a^2+2ab+b^2 = (a+b)^2
We need to find value of * which is 2ab
In your equation = [tex]\sqrt{6.25} = 2.5 and \sqrt{1/4} = 0.5\\Now 2ab = 2 * 2.5 * 0.5\\ = 2.5\\\\\\* = 2.5ab[/tex]
From midnight to 6:00 am, the temperature rose 1.05°C each hour. If the temperature at 6:00 am was -5.7°C, what was the temperature at midnight?
Answer:
13.2 C
Step-by-step explanation:
6am the temp is at -5.7
from 6am to 12pm is 18 hours apart
so if the temp rises at 1.05 every hour you multiply 1.05*18= 18.9
18.9-5.7=13.2

Is (1, -3) a solution of f (x) = |x + 2|?
Answer:
No.
Step-by-step explanation:
f(1)=|(1)+2|
f(1)=|3|
=3
x=1 & y=3
Answer: (1,3)
so
(1,-3) is not a solution because "y" is supposed to equal 3 not -3

Hey there!☺
[tex]Answer:\boxed{a<\frac{-1}{6}}[/tex]
[tex]Explanation:[/tex]
[tex]a+\frac{5}{6}<\frac{2}{3}[/tex]
We only have one step in this inequality which is subtract 5/6 from both sides:
[tex]a+\frac{5}{6}-\frac{5}{6}<\frac{2}{3}-\frac{5}{6}\\a<\frac{-1}{6}[/tex]
[tex]a<\frac{-1}{6}[/tex] is our answer.

what equation shows that 9 is a factor of 72
Answer:
9 x 8 = 72
This equation shows that 9 is a factor of 72 because 9 times something is 72 in this equation. Hope it helps!
Answer:
72 / 9 = 8
Step-by-step explanation:
This equation shows that 9 is a factor of 72 because the number at the end comes out as a whole number. If it wasn't a whole number, then 9 would not be a factor of 72. Hope this helps!

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if b c=9, a=7?
Answer
square root of 32
Step-by-step explanation:
in a right triangle we can use Pythagorean theorem to find B
[tex]C^{2} =A^{2}+B^{2} \\\\ 9^{2}=7^{2}+B^{2} \\81=49+B^{2} \\81-49=B^{2} 32=B^{2}\\ B=\sqrt{32}[/tex]we substitute C for 9 and A for 7
