Is it mathematically correct to say that:

Step2247 [10]

Answer: Yes

Step-by-step explanation:

Since the numerator is multiplying square root 13 by square root 2, we can break them apart.

$\displaystyle \frac{\sqrt{13*2}}{\sqrt{13}} =\frac{\sqrt{13}*\sqrt{2} }{\sqrt{13}}$

You are correct, $\sqrt{13}$ over $\sqrt{13}$ is equal to one, so we can "cancel them out" of our expression.

$\displaystyle \frac{\sqrt{13} }{\sqrt{13}} = 1$

This leaves us with: $\sqrt{2}$

We can also test this by using a calculator:

$\frac{\sqrt{13*2}}{\sqrt{13}} \approx 1.41421356\\\sqrt{2} \approx 1.41421356\\1.41421356=1.41421356$

Shirts are on sale at a price of $50 for 4. How many shirts can be purchased for $125?

mezya [45]

Answer:

10 shirts

Step-by-step explanation:

We can use a ratio to solve

50 dollars 125 dollars

-------------------- = -------------------

4 shirts x shirts

Using cross products

50 *x = 4 * 125

50x = 500

Divide each side by 50

50x/50 = 500/50

x = 10

(i) Challenge: Thembi received 8% discount on an item which cost

Paul [167]

Answer:

$x = 0.25$

Step-by-step explanation:

Given

$Cost\ Price = 6 + x$

$Discount =8\%$

$Amount\ Paid = R6 - x$

Required

Find x

First, we calculate the amount paid in terms of the cost price.

This is calculated using:

$Amount\ Paid = Cost\ Price * (100\% - Discount)$

$Amount\ Paid = (6 + x) * (100\% - 8\%)$

$Amount\ Paid = (6 + x) * 92\%$

Express as decimal

$Amount\ Paid = (6 + x) * 0.92$

Open bracket

$Amount\ Paid = 5.52 + 0.92x$

So, we have:

$Amount\ Paid = 5.52 + 0.92x$ and

$Amount\ Paid = R6 - x$ ---- given

Equate both

$6 - x = 5.52 + 0.92x$

Collect like terms

$- x -0.92x= 5.52-6$

$-1.92x= -0.48$

$1.92x= 0.48$

Solve for x

$x = \frac{0.48}{1.92}$

$x = 0.25$
