$283.50

Step-by-step explanation:

210x0.35=73.5

73.5+210=283.5

Answer: $283.50

Step-by-step explanation:

Okie dokie! All you have to do is Multiply 210 by 135%, since 135% is a markup of 35%. Make sure to convert your percent's to decimals.

210 x 1.35 = 283.50.

Answer:

Rs. 1315

Step-by-step explanation:

He bought 300 saris

0.7(300) were sold at 1500 / piece

0.3(300) were sold at 1350/ piece

210 were sold at 1500/ piece = 315000

90 were sold at 1350/piece = 121500

Total amount  = 315000+121500 = 436500

Profit = 42000

Subtract:

436500 - 42000 = 394500

394500 is the price for 300 saris

Divide by 300

394500 / 300 = 1315

He purchased one sari at 1315

Answer:

A) [tex]x = y^{2}[/tex]

Step-by-step explanation:

An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:

[tex]y = f(x)[/tex] (1)

Where [tex]y[/tex] is the dependent variable.

According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.

Answer: D is right

Step-by-step explanation:     time is 4 hours when there are 7 electricians.

the answer is a

Step-by-step explanation:

a is .75 shaded in then there are 5 sections in the shaded area

Answer:

D is the correct option.

Step-by-step explanation:

I used the elimination method to solve this. so we can see that there is 100 boxes and we need to 75 to be shaded. only C and D have 75 squares shaded so we can eliminate A and B. now we have to divide by 5. Square C is divided 3 times while square D is divided 5 times, so square D is correct.

Step-by-step explanation:

There are 2.4 cups of sugar in the gallon of sweet tea.

The conversion of fluid measure takes a standard analysis where the assumed container of a particular fluid is related to another container.

here, we have,

For example, we have two containers here:

The glass cup

The gallon

We need to know how many glass cups that are present in a gallon. From standard conversion rates:

1 gallon = 16 cups

However,

We learned that 1 cup contains 15% of sugar; Therefore, 16 cups will contain:

= 16 × 0.15

= 2.4 cups of sugar

Answer:

subject?

Step-by-step explanation:

Answer:

Solution given:

here

base[b]=x

perpendicular [p]=9√3

hypotenuse [h]=y

we have

sin 30=p/h

1/2=9√3/y

y=18√3 or 31.176

again

cos 30°=b/h

√3/2=x/18√3

x=3×18/2=27

x=27

The equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].

Equivalent expressions are expressions that work the same even though they look different.

According to the given question.

we have an expression [tex]w^{4} -36[/tex]

The equivalent expression of the above expression can be given by

[tex]w^{4} -36[/tex]

⇒ [tex](w^{2}) ^{2} -(6)^{2}[/tex]

⇒[tex](w^{2}-6)(w^{2} +6)[/tex]      (by using the property [tex]a^{2} -b^{2} = (a-b)(a+b)[/tex] )

Hence, the equivalent expression of [tex]w^{4} -36[/tex] is [tex](w^{2} -6)(w^{2} +6)[/tex].

Thus, option D is correct.

Answer: 384 ft. squared

Step-by-step explanation:

Hey!

So for this problem we first need to convert our scale lengths to feet. Since 4 in. equals 8 ft. that would make the 12 in side 24 ft. long because 12 divided by 4 is 3 and 3 time 8 is 24. We do this because we need to figure out how many times 4 inches are in each length because that how many time the 8ft is in the real length.

Next, we would do the same for the next side and divide 8 by 4 which is 2 and then we multiple 8ft by 2. We then get 16 ft which is our other side length.

After that, we just do our area formula which is length x width or in this case 16 x 24. This gets us 384 and then we add our unit and squared at the end and have our answer.

Hope this helped! :D
