Answer:

the better buy is that from the second store as it is cheaper than that purchased from the first store

Step-by-step explanation:

Given that :

First store :

Amount paid = $12.16

Pounds of shrimps = 4.07

Unit price :

Amount paid / pounds of shrimps

$12.16 / 4.07 = $2.9877

= $2.99 = 299 cents

second store :

Amount paid = $14.99

Pounds of shrimps = 5.11

Unit price :

Amount paid / pounds of shrimps

$14.99 / 5.11 = $2.933

= 2.93 = 293 cents

Hence, the better buy is that from the second store as it is cheaper than that purchased from the first store

Alina is able to swim at a rate of about 2.5 miles per hour. Talia is able to swim at a rate of 1.8 meters per second. Which sta

Remark

Without being given choices, we can get answers but they may not be listed among your. The important think is to be working in the same units

Convert miles/hour to m/sec

$\frac{2.5 mi}{h}*\frac{1 h}{3600 sec}*\frac{1.6 km}{1 mi}*\frac{1000 m}{1 km}$

Now just multiply all the numerators together and divide by all the denominators.

Numerators: 2.5 * 1.6 * 1000 = 4000

Denominators: 3600

numerator/denominator = 4000/3600 m/s = 1.111 m/s

Conclusion

Talia is a much faster swimmer than Alina because 1.8 is greater than 1.11. Both numbers are in m/s.

2.5 miles / hour = 1.

This year, the Start-of-Term feast had three desserts: chocolate eclairs, raspberry tarts, and jam doughnuts. On the dessert tab

Nostrana [21]

Let
x = chocolate eclairs
y = raspberry tarts
z = jam donuts
We write the following system of equations:
z = (2/3) x
x = (6/5) y
x + y + z = 1320
Solving for y:
z = (2/3) (6/5) y
z = (4/5) y
then
(6/5) y + y + (4/5) y = 1320
3y = 1320
y = 1230/3 = 410
answer
there were 410 tarts on the dessert table

Which of the following is equivalent to four raised to the power of negative two.?

AfilCa [17]

To raise a number n to a negative power you simply take the fraction 1/n and raise it to the (positive) power you want.

${n}^{ - m} = { \frac{1}{n} }^{m}$

So 2^-2 is ¼.
