Zola is thinking of a number. If the number is divided by 7.5, the quotient is 62. what is zolas number?

____ [38]

Okay, so I would multiply 62*7.5 to get 465.

To check the solution, make sure it follows the rules as in the word problem.

If you divide 465 by 7.5 you do get 62, so the solution is 465.

Mathematically, the equation would be

x
- = 62
7.5
I would multiply x/7.5 by 7.5/1 (to cancel it out) and 62/1 by 7.5 which is basically the same solution as above.

Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D.

Julli [10]

Answer:

$AB = 6$

Step-by-step explanation:

Given

$BC = 3.8$

$A'B' = 15$

$B'C' = 9.5$

Required

Determine the length of AB

Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:

$A'B' : AB = B'C' : BC$

Substitute values for A'B', B'C' and BC

$15 : AB = 9.5 : 3.8$

Express the ratio as fractions:

$\frac{AB}{15} = \frac{3.8}{9.5}$

Multiply through by 14

$15 * \frac{AB}{15} = \frac{3.8}{9.5} * 15$

$AB = \frac{3.8}{9.5} * 15$

$AB = \frac{3.8* 15}{9.5}$

$AB = \frac{57}{9.5}$

$AB = 6$

Rahul sold a painting at 10% profit. If he had sold it for 240 more, he would have made 15% profit. What is the C.P. of the pain

dangina [55]

Answer:

$4800

Step-by-step explanation:

Let x be the C.P of the painting.

Profit=10% of x

Profit= $\frac{10}{100}\times x=\frac{10x}{100}$

If S.P increase by 240 then

Profit=15% of x= $\frac{15x}{100}$

For first case

S.P=C.P+ Profit

S.P=x+10x/100

S.P= $\frac{100x+10x}{100}=\frac{110}{100}x$

For second case

New S.P $=x+\frac{15}{100}x$

= $\frac{115}{100}x$

According to question

$240+S.P=\frac{115}{100}x$

$240+\frac{110x}{100}=\frac{115}{100}x$

$240=\frac{115}{100}x-\frac{110x}{100}$

$240=\frac{115x-110x}{100}$

$240=\frac{5}{100}x$

$x=\frac{240\times 100}{5}$

$x=4800$

Hence, the C.P of the painting=$4800
