If matherens bannanas cost $1.98 for 3lbs. At winn dixie bannanas cost $2.97 for 4lbs. Which store has the better price. Please
Natasha_Volkova [10]

Answer: Matherens has the better price

Step-by-step explanation:

To find the better price, all we have to do is divide the price by the number of pounds to find how much one pound is for each store.

Matherens: 1.98 ÷ 3 = 0.66

That means 1 pound of bananas at Matherens is 66 cents.

Winn Dixie: 2.97 ÷ 4 = 0.74

That means 1 pound of bananas at Winn Dixie is 74 cents.

This means that Matherens is charging less per pound of banana.

Mildred’s salary has increased from £24,600 to £25,338. By what percentage has her salary increase?
Illusion [34]

Answer:

<h3>The answer is 3%</h3>

Step-by-step explanation:

To find the percentage increase we use the formula

Percentage  \: change =  \frac{ change}{original \: quantity}  \times 100

To find the change subtract the smaller quantity from the bigger one

From the question

original price = $24,600

Current price = $ 25,338

Change = $25,338 - $ 24,600

Change = $ 738

So the percentage increase is

\frac{738}{24600}  \times 100

=  \frac{3}{100}  \times 100

We have the final answer as

<h3>Percentage increase = 3%</h3>

Hope this helps you

A man drove 11 mi directly east from his home, made a left turn at an intersection, and then traveled 9 mi north to his place of
ludmilkaskok [199]

Answer: 14 miles

Step-by-step explanation:

In the attached figure we can see the two segments the man drove, where the d is the distance of a road that goes from the man's home directly to his work.

It should be noted that dis also the hypotenuse of the righ triangle formed. Hence, we can use the Pithagorean theorem to find this distance:

d=\sqrt{(11 mi)^{2} + (9 mi)^{2}}

Then:

d=14.21 mi \approx 14 mi
