Answer: See explanation: 10, 1, 1, -7

Step-by-step explanation:

I'll assume you are working with Excel. The Product function multiplies all the cells given in the specified range. Here, those are cells A2 through A5. As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2. If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.

Initial: 10, 5, 0, -7 B2=0

Change: 10, 1, 1, -7 B2 = -70

Other combinations are possible.

A store sells sandals for 25% off the regular price. The regular price of the sandals is $32.50. what is the sale?

ozzi

Answer:

$24.375

Step-by-step explanation:

Regular price of sandals = $32.50

Store sells sandals for 25% of the regular price.

Hence selling price =(100-25)% of the regular price.

In other words, selling price = 75% of regular price

= 75% of $32.50

= $\frac{75}{100}*32.50$

= $24.375$

Hence the sale price of the sandals is $24.375

This is $8.125 less than the regular price of the sandal.

Pls answer me this all question

Scorpion4ik [409]

Answer:

a. $5 \frac{21}{40}$

b. $\frac{1}{42}$

Step-by-step explanation:

$a. \: 12 \frac{2}{5} - 6 \frac{7}{8}$

$\frac{62}{5} - \frac{55}{8}$

$\frac{62}{8} \times \frac{8}{8} - \frac{55}{8} \times \frac{5}{5}$

$\frac{62 \times 8 - 55 \times 5}{40}$

$\frac{221}{40}$

$5 \frac{21}{40}$

$b. \: \frac{3}{14} - \frac{4}{21}$

$\frac{3}{14} \times \frac{3}{3} - \frac{4}{21} \times \frac{2}{2}$

$\frac{3 \times 3}{42} - \frac{4 \times 2}{42}$

$\frac{1}{42}$

Hope it is helpful....
