With this question, it's mostly just trial and error.

\sqrt{26}<13 can be converted to 5.09901951<13, which is true.

\sqrt{251}<13 can be converted to 15.8429795<13, which is false.

\sqrt{28561}<13 can be converted to 169<13, which is false.

\sqrt{170}<13 can be converted to 13.0384048<13, which is false.

\sqrt{1}<13 can be converted to 1<13, which is true.

\sqrt{15}<13 can be converted to 3.87298335<13, which is true.

Therefore, A, E and F are true.

**This question involves using inequalities and converting surds to numbers/decimals, which you may want to practice. I'm always happy to help!

Kurt has a collection of 155 United States and Canadian stamps. He has 1.5 times as many United States stamps as Canadian stamps
stealth61 [152]

Kurt has 93 United States stamps in his collection

Step-by-step explanation:

The given is:

  • Kurt has a collection of 155 United States and Canadian stamps
  • He has 1.5 times as many United States stamps as Canadian stamps

We need to find how many United  States stamps Kurt has in his collection

Assume that kart has x Canadian stamps

∵ kart has x Canadian stamps

∵ He has 1.5 times as many United States stamps as Canadian stamps

- That means the number of United States stamps is 1.5 times

   the number of the Canadian stamps

∴ The number of the United States stamps = 1.5 x

∵ Kurt has a collection of 155 United States and Canadian stamps

- Add the two numbers of stamps and equate the answer by 155

∴ x + 1.5 x = 155

- Add like terms

∴ 2.5 x = 155

- Divide both sides by 2.5

∴ x = 62

∵ The number of United States stamps = 1.5 x

∴ The number of United States stamps = 1.5(62)

∴ The number of United States stamps = 93 stamps

Kurt has 93 United States stamps in his collection

Bob the builder is making 480kg of concrete mix
vichka [17]

To answer this item, we are first to determine the common factor between the amounts of the cement, sand, and gravel.


If we let x be this factor, the amount of the cement would be x. Similarly, the amount of sand is 3x, and lastly the amount of gravel is 4x. Then, we establish the equation that would let us relate the amounts.


      x + 3x + 4x = 480


Simplifying,

    8x = 480

     x = 60


Hence, the amount of cement is 60 kg, that of sand is 180 kg. Lastly, the amount of gravel is 240 kg.
