Simone applied the distributive property using the greatest common factor to determine the expression that is equivalent to 24 + 56. Her work is shown below.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
24 + 56 = 8 (4 + 7)
What statement best describes Simone’s error?
Simone did not use the correct factors for 24 in the equation.
Simone did not use the correct factors for 56 in the equation.
Simone did not use the greatest common factor in the equation.
Simone did not use the correct operations in the equation.

Answer:P2,700,000
Step-by-step explanation:
P100,000 must be added to the purchase price every year from 2009 to 2021. A formula calculating the value, V, as a function of time, t, where t is years since 2009, would be:
V(t) = P1,500,000 + (t - 2009)*(100,000)
V(2021) = P1,500,000 + (2021 - 2009)*(100,000)
V(2021) = P2,700,000

Answer:
[tex]\boxed{\sf x=-3\frac{3}{20}}[/tex]
Step-by-step explanation:
[tex]\sf -4\cfrac{2}{5}=x-1\cfrac{1}{4}[/tex]
Multiply Both sides by 20, Which is the LCM of 5, 4:
[tex]\mapsto \sf (4\times 5+2)=20x-5(4+1)[/tex]
Multiply 4 and 5= 20, and add 20 +2 =22
[tex]\mapsto \sf -4\times 22=20x-5(4+1)[/tex]
Multiply -4 * 22 = -88, and then add 4+1=5:
[tex]\mapsto \sf -88=20x-5\times 5[/tex]
Multiply -5 *5 = -25:
[tex]\mapsto \sf -88=20x-25[/tex]
Now, swap sides:
[tex]\mapsto \sf 20x-25=-88[/tex]
Add 25 to both sides:
[tex]\mapsto \sf 20x=-88+25[/tex]
[tex]\mapsto \sf 20x=-63[/tex]
Divide both sides by 20:
[tex]\mapsto \sf x=\cfrac{-63}{20}[/tex]
Now, convert an improper fraction to a mixed number: →
[tex]\mapsto \sf x= -3\cfrac{3}{20}[/tex]

Answer:
12 2/5 or 12.4
Step-by-step explanation:
Find the sum
[tex]\sum_{k=1}^{\infty}\sum_{n=1}^{\infty} \frac{k}{ {2}^{n + k} } . \\ [/tex]
Correct answer will be mark as brainliest answer.
[tex] \large\underline{\sf{Solution-}}[/tex]
Given series is
[tex]\rm \longmapsto\:\displaystyle\sum_{k=1}^{\infty}\rm \displaystyle\sum_{n=1}^{\infty}\rm \frac{k}{ {2}^{n + k} } [/tex]
can be further rewritten as
[tex]\rm \: = \: \:\displaystyle\sum_{k=1}^{\infty}\rm \displaystyle\sum_{n=1}^{\infty}\rm \frac{k}{ {2}^{k} . {2}^{n} } [/tex]
can be further rewritten as
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \bigg[\dfrac{k}{ {2}^{k}}\displaystyle\sum_{n=1}^{\infty}\rm \dfrac{1}{ {2}^{n} } \bigg][/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \dfrac{k}{ {2}^{k} }\bigg(\dfrac{1}{2} + \dfrac{1}{ {2}^{2} } + \dfrac{1}{ {2}^{3} } - - - \infty \bigg) [/tex]
So, its an infinite GP series with
[tex] \purple{\rm \longmapsto\:a = \dfrac{1}{2}}[/tex]
[tex] \purple{\rm \longmapsto\:r = \dfrac{1}{2}}[/tex]
We know,
Sum of infinite GP series with common ratio r ( - 1 < r < 1 ) and first term a is given by
[tex]\boxed{\tt{ \: \: S_ \infty = \frac{a}{1 - r} , \: \: provided \: that \: |r| < 1}}[/tex]
So, 1using this, we get
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }\bigg( \frac{ \frac{1}{2} }{1 - \frac{1}{2} }\bigg)[/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }\bigg( \frac{ \frac{1}{2} }{ \frac{2 - 1}{2} }\bigg)[/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }\bigg( \frac{ \frac{1}{2} }{ \frac{1}{2} }\bigg)[/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }[/tex]
[tex]\rm \: = \: \dfrac{1}{2} + \dfrac{2}{ {2}^{2} } + \dfrac{3}{ {2}^{3} } + \dfrac{4}{ {2}^{4} } + - - - \infty [/tex]
Let assume that
[tex]\rm \longmapsto\:S_ \infty = \: \dfrac{1}{2} + \dfrac{2}{ {2}^{2} } + \dfrac{3}{ {2}^{3} } + \dfrac{4}{ {2}^{4} } + - - - \infty [/tex]
Now, its an infinite Arithmetico Geometrico Series, So multiply by 1/2 we get
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{1}{ {2}^{2} } + \dfrac{2}{ {2}^{3} } + \dfrac{3}{ {2}^{4} } + \dfrac{4}{ {2}^{5} } + - - - \infty [/tex]
On Subtracting above two equations, we get
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{1}{2} + \dfrac{1}{ {2}^{2} } + \dfrac{1}{ {2}^{3} } + \dfrac{1}{ {2}^{4} } + - - - \infty [/tex]
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{ \dfrac{1}{2} }{1 - \dfrac{1}{2} } [/tex]
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{ \dfrac{1}{2} }{ \dfrac{1}{2} } [/tex]
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: 1[/tex]
[tex]\bf\implies \:S_ \infty = 2[/tex]
Hence,
[tex] \\ \rm \longmapsto\:\boxed{\tt{ \: \: \: \: \displaystyle\sum_{k=1}^{\infty}\rm \displaystyle\sum_{n=1}^{\infty}\rm \frac{k}{ {2}^{n + k} } = 2 \: \: \: \: }} \\ [/tex]

There are 3 teaspoons in 1 tablespoon. How many teaspoons are there in 6 tablespoons?
Answer:
18
Step-by-step explanation:
we can solve this as a ratio, from teaspoons to tablespoon is 3:1. if the tablespoon is 6 then the ratio becomes ?:6. Since we multiplied 1 by 6 we have to multiply 3 by 6 making the ratio 18:6.

A sloth crawled 6 cm in one second. What was its speed in km/h? (1 hr =
3600 s) (1 km = 100,000 cm)
Step-by-step explanation:
it was measured that the south crawled 6cm in 1 second.
that gets expressed by the ratio
6 cm/sec or formally correct 6/1 cm/sec.
to get that speed in km/h (kilometers per hour), we need to transform the denominator of that ratio to 1 hour.
the only way we can manipulate a fraction or ratio without changing its value is by multiplying numerator and denominator (top and bottom) by the same factor.
like x/y × 3/3 = 3x/3y.
the driver behind a question of this kind is again the denominator. we want the denominator to appear as 1 hour.
so, what do I need to multiply 1 second with to get 1 hour ?
the problem definition tells us : 3600, as there are 3600 seconds in 1 hour.
so, we need to multiply
6/1 × 3600/3600 = (6×3600)/3600 = 21600/3600 =
21600cm/1 hour.
and now, how many km are 21600 cm ?
1 km = 100000 cm
so,
21600cm = 21600/100000 km = 0.216 km
therefore, or full answer is
the sloth's speed was 0.216 km/h

Type the integer that makes the following addition sentence true: 9 + what = 2
I believe the answer to be (-7)
Answer:
-7
Step-by-step explanation:
Step 1: Make an equation.
[tex]9 + x = 2[/tex]Step 2: Subtract 9 from both sides.
[tex]9 + x - 9 = 2 - 9[/tex] [tex]x = -7[/tex]Step 3: Check if solution is correct.
[tex]9 + (-7) = 2[/tex] [tex]9 - 7 = 2[/tex] [tex]2 = 2[/tex]Therefore, the integer that makes the addition sentence true is -7.

A shipping container is in the shape of a right rectangular prism with a length
of 13.5 feet, a width of 11 feet, and a height of 5-5 feet. The container is
completely filled with contents that weigh, on average, 0.93 pound per cubic
foot. What is the weight of the contents in the container, to the nearest
pound?
Answer:760 lbs
Step-by-step explanation:
The volume of a right rectanglar prism (i.e., a box) is length*width*height.
Volume = (13.5)*(11)*(5.5) = 817 ft^3
Density = 0.93 lb/ft^3
Weight of container contents = (817 ft^3)*(0.93 lg/ft^3) = 760 lbs
