Dave has $15 to

1 answer:

6 0

Hello there! Given Dave only has $15 and the book is $8, we can assume he already paid for the book:

$15 - $8 = $7

Because Dave has $7 left, we can use the following inequality to show that he can spend up to $7 at maximum on both cards:

c = $7

Given Dave buys 2 cards, we can divide 7 by 2 to find how much Dave spends on each card:

7 divided by 2 gives us 3.50

Hence, Dave can spend $3.50 on each card.

Hope this helps!

How many different 7-digit number plates can be made if the first 2 digits are letters and the last 5 digits are numbers, for ex

saw5 [17]

Answer:

We can use seven letters and numbers.

I am assuming that any numeral in the range 0..9 or any letter from the English alphabet A..Z can appear in any position, with no blank spaces allowed and no restrictions on repetition. I am also assuming that plates with fewer than seven letters and numbers are not allowed.

So, for example A879BX8 is acceptable, so are 5555555 and ABCDEFG, but not A.123.ZX or…..7A, where the dot represents a space.

I am also assuming that you can only use upper case letters.

With these restrictions, there are 36 possibilities for each space and the total number of valid number plates would be 36^7 = 78,364,164,096, let's say about 78 billion.

It is estimated that there are about 1.3 billion cars, trucks and buses in the road today. This number plate system therefore allows more than enough unique license plates. I'd even hazard a guess that it might be more than enough for every road vehicle that has ever been built or ever will be.

In practice there would be other restrictions, for example only letters in some positions and only numbers in others. There'd still be plenty to go around.

Determine the length of the missing side in each of the right triangles below using the Pythagorean Theorem: a2 + b2 = c2.

lara31 [8.8K]

The answer is 12
${13}^{2} = {5}^{2} + {b}^{2} \\ {b}^{2} = {13}^{2} - {5}^{2} \\ b {}^{2} = 169 - 25 = 144$
$b = \sqrt{144} = 12$

good luck

Haruka hiked several kilometers in the morning. She hiked only 666 kilometers in the afternoon, which was 25\%25%25, percent les

katen-ka-za [31]

Answer:

She hiked 1,554 kilometers in all.

Step-by-step explanation:

Let the hiking kilometers for morning be x

Given that:

Hiking kilometers in afternoon = 666

According to given condition that afternoon kilometers are 25% less than morning:

x = 666 + 25% of x

By simplifying:

x = 666 + 0.25x

x - 0.25x = 666

0.75x = 666

Dividing both sides by 0.75 we get:

x = 666/0.75

x = 888 kilometers

She hiked 888 kilometers in morning

And

Total = 888 + 666 =1554 km

i hope it will help you!
