Answer:

3/4 × 2/5 = 3/10

Step-by-step explanation:

3/4 × 2/5 is equivalent to 3/4 of 2/5

First, you have to divide the number line in 5 parts, and locate 2/5 (see figure attached)

Next, you have to divide in 4 parts the segment that represents 2/5, and locate 3/4 of 2/5

If you continue dividing the whole line with the previous segment length, you will divide the whole line into 10 parts.

Then, 3/4 of 2/5 is 3/10.

Hello there can anyone solve this plz (chart is attached):

stich3 [128]

Answer:

$h^\prime(1)=14$

Step-by-step explanation:

We have the function:

$h(x)=f[f(x)]$

And we want to find:

$h^\prime(1)$

So, we will differentiate function h. By the chain rule, this yields:

$h^\prime(x)=f^\prime[f(x)]\cdot f^\prime(x)$

Then it follows that:

$h^\prime(1)=f^\prime[f(1)]\cdot f^\prime(1)$

Using the table, we acquire:

$h^\prime(1)=f^\prime(3)\cdot2$

And using the table again, we acquire:

$h^\prime(1)=7\cdot 2$

Evaluate. Hence:

$h^\prime(1)=14$

Tobias's music store bought a piano at the wholesale price of $550. Tobias marked up the price 35%. What was the amount of marku

Mrrafil [7]

Answer:

A. $58.50

B. $80

C. No. The markup was 33 1/3%

Step-by-step explanation:

You are expected to know the relevant relationship is ...

cost + markup = selling price . . . . also called "store price" in this problem

___

A. The markup is 30% × $45 = $13.50, so the store price is ...

$45 + 13.50 = $58.50

___

B. When the 30% markup is added to the 100% cost, the selling price is 130% of the cost, or 1.30 times the cost. Here you have ...

$104 = 1.30 × cost

$104/1.3 = cost = $80 . . . . . divide by the coefficient of cost

___

C. The markup is $100 -75 = $25, so the markup percentage based on cost is ...

$25/$75 × 100% = 33 1/3%

This is not 30%.
