Step-by-step explanation:
Lateral surface area of cube = 4a²
4a² = 400
a² = 400÷4
a² = 100
a = √100 = √10*10
a = 10 cm
Total surface area = 6a²
= 6 * 10²
= 6* 100
= 600 cm²

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is is given as
The fraction of bookshelf Kiki painted on Monday = 1 / 5
The fraction of bookshelf Kiki painted on Tuesday = 5 / 6
Now , the equation will be
Therefore , the total bookshelf Kiki painted is = fraction of bookshelf Kiki painted on Monday + fraction of bookshelf Kiki painted on Tuesday
Substituting the values in the equation , we get
The total bookshelf Kiki painted is = 1/5 + 5/6
The total bookshelf Kiki painted is = 11/30
Therefore , the value of A is 11/30
Hence , The total bookshelf Kiki painted is 11/30

Mr. Jones and Mr. Smith both plan to retire in 5 years. Mr. Jones has invested $250 per
month in a 401k retirement account for 20 years, and Mr. Smith has invested $500 a month
in a 401k retirement account for 10 years. Mr. Jones and Mr. Smith invested in the same
accounts yielding the same interest rate. Which statement about the retirement investments
of Mr. Jones and Mr. Smith is most likely to be true?
Mr.Smith will have more money saved because he invested more money each month.
Mr. Smith and Mr. Jones will have the same amount in their retirement funds.
Mr. Jones will have more money because he invested for a longer period of time.
cannot determine
Answer:
i don't know, i just want to know if you got it right
Step-by-step explanation:
The correct statement (C) "Mr. Jones will have more money because he invested for a longer period of time" is correct.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
It is given that:
Mr. Jones and Mr. Smith both plan to retire in 5 years.
From the formula:
The rate of interest is the same for both cases.
The duration for Mr. Jones is 20 years
The Initial investment amount for Mr. Jones = $250
The duration for Mr. Smith is 10 years
The initial investment amount for Mr. Smith = $500
Mr. Jones will have more money because he invested for a longer period of time.
Thus, the correct statement (C) "Mr. Jones will have more money because he invested for a longer period of time" is correct.

If the fraction (352/x-10) is equivalent to -22, find the value of x.
Answer:
The value of x is -6
Step-by-step explanation:
Let us equate the fraction by its equivalent
∵ [tex]\frac{352}{x-10}[/tex] = -22
→ Multiply both sides by (x - 10) to cancel the denominator of the left side
∴ [tex]\frac{352}{x-10}[/tex] × (x - 10) = -22 × (x - 10)
∴ 352 = -22(x - 10)
→ Simplify the right side by multiplying -22 by the bracket (x - 10)
∵ 352 = -22(x) - 22(-10)
∴ 352 = -22x + 220
→ Add 22x to both sides
∵ 22x + 352 = -22x + 22x + 220
∴ 22x + 352 = 220
→ Subtract 352 from both sides
∴ 22x + 352 - 352 = 220 - 352
∴ 22x = - 132
→ Divide both sides by 22 to find x
∴ [tex]\frac{22x}{22}=-\frac{132}{22}[/tex]
∴ x = -6
∴ The value of x is -6

Answer: 11/4 in decimal form 2.75
Step-by-step explanation: 4x−y=10
4x−y=10
Step 1: Add y to both sides.
4x−y+y=10+y
4x=y+10
Step 2: Divide both sides by 4.
4x/4=y+10/4
x=1/4y+5/2 = 11/4= 2.75

13. Nine days ago, the gas tank on Sue's car was filled with 24 gallons of gasoline. Today there are 6 gallons of gasoline.
a. What integer represents the change of gasoline in the past seven days?
b. What is the change in gasoline in gallons per day (if she used the same amount every day)?
Gasoline difference = 24 - 6 gallons
= 18 gallons
9 days = 6 gallons

Find the slope of the line containing the pair of points.
(-11,12) and (7, - 2)

-7/9
Step-by-step explanation:
The slope of the line is -7/9
12+2/-11-7=
14/-18=
7/-9=
-7/9
Answer:
The answer is -7/9
Step-by-step explanation:By using the Slope Formula (y2-y1)/(x2-x1) you label the the points ( y2=-2, y1=12), (x2=7, x1=-11) then you plug the answer into the formula -2-12/7- -11 then when you figure that out you get 14/18 but that's not the answer. You need to simplify it then the correct answer is -7/9

Find the sum to infinity of the infinite G.P.
1-½+¼........
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The sum to infinity of a GP is
[tex]S_{infinity}[/tex] = [tex]\frac{a}{1-r}[/tex] ; | r | < 1
where a is the first term and r the common ratio
Here a = 1 and r = - [tex]\frac{1}{2}[/tex] ÷ 1 = - [tex]\frac{1}{2}[/tex] , thus
[tex]S_{infinity}[/tex] = [tex]\frac{1}{1-(-\frac{1}{2}) }[/tex] = [tex]\frac{1}{1+\frac{1}{2} }[/tex] = [tex]\frac{1}{\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex]
Answer:
2/3
Step-by-step explanation:
1-1/2+1/4.....
[tex]r=\frac{\frac{-1}{2} }{1} =-\frac{1}{2} \\if~|r|<1,then~s_{\infty}=\frac{a}{1-r} ,a=first~term.\\s_{\infty}=\frac{1}{1-(\frac{-1}{2}) } =\frac{1}{1+\frac{1}{2} } =\frac{1}{\frac{3}{2} } =\frac{2}{3}[/tex]

This is an opinion based question so plz don't delete i would actually like to know what people think.
Most of the math we learn in school do you actually think that we use half of it?
Also tell me how to give brainliest in your answer so I can give full points
please actually answer the question this is worth 50 points and i dont want to waste them
Answer:
Some subjects are more important than others. You have to be working in a field where the concepts you learn in school.
I'd say that everything you learn in middle school and Algebra 1 + 2 , maybe a little of geometry you'll use at some point in your life.
Step-by-step explanation:
Everyone has asked themselves: When will I use math? Well, hundreds of careers use skills learned in high school math on a daily basis. The truth is virtually every career you could choose will build on the basic skills learned in High School Math.
But there are a number of craft and fine arts careers that do not require math skills or involve using them regularly, such as being a painter or sketch artist. Craft and fine artists produce original works that will be displayed or sold, and they may work with a range of materials, such as paint, glass or ink.
To conclude I might say that math is important and everyone should know more than just some basic skills in math.Life is long and sometime harsh for most of us and not always we get in life what we want,probably we will end up doing a job that it was not our dream job.
Or our preferences might change depending on different aspects of life.So knowing a 'little bit' from every subject we do in school is not a bad thing,at the end we know all that greatest things are achived will a hard work!So we should learn as much as we can! Math especially!
And all our hard work will be payed at the end,just remember this!
