Help. How do u convert units within a measurement system

1 answer:

4 0

Step 1. Identify the unit you have
Step 2. Identify the unit you want to covert to
Step 3. Count the number of units between them

(If you are going from a larger unit to a smaller unit, you multiply by 10 successively.)

Joshua can purchase tile at one store for $0.99 per tile but he he will have to rent a tile saw for $25 at another store he can

natita [175]

Answer: the number of tiles will be 49

Step-by-step explanation:

Let x represent the number of tiles that Joshua can buy at either stores.

one store for $0.99 per tile but he he will have to rent a tile saw for $25. Let the total cost of buying x tiles in this store be y. Therefore

y = 0.99x + 25

At another store, he can buy a tile for $1.50 per tile and borrow a tile saw for free. Let the total cost of buying x tiles in this store be z. Therefore

z = 1.5x

To determine the number of tiles for which both costs will be the same, we will equate y to z. It becomes

0.99x + 25 = 1.5x

1.5x - 0.99x = 25

0.51x = 25

x = 25/0.51

x = 49

Lela to determine the largest of the following real numbers

Lisa [10]

In ths question, we have a set of numbers, and we have to determine the largest real number

$\sqrt{30}-5 , 3 \sqrt{14}-6 , 6.03, 2 \pi$

First we need to convert each of them in decimal form. That is

$\sqrt{30}-5 =0.477
\\
3 \sqrt{14}-6 = 5.22
\\
6.03=6.03
\\
2 \pi = 2*314=6.28$

So we have

0.477, 5.22,6.03,6.28

And 6.28 is the largest among them. Therefore correct option is 2pi .

How much fencing does she need to buy

kati45 [8]

Its is surprising that no one attempted this question for over a week.

As in all geometry problems, start with a diagram (shown).

Then we realize right away that AB=sqrt(8^2+2^2)=sqrt(68)=2sqrt(17)

BC=sqrt(4^2+1^2)=sqrt(17)

The perimeter is therefore twice the sum of AB+BC=2(2sqrt(17)+sqrt(17))

2(3sqrt(17))=6 sqrt(17) We can estimate sqrt(17)=4.125, so 6sqrt(17)=24.75 which is close enough to get the correct answer choice.

Have a good day.
