Mathematics

8 0

Answer

Decimal is a term that describes the base-10 number system, probably the most commonly used number system. The decimal number system consists of ten single- digit numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The number after 9 is 10. The number after 19 is 20 and so forth. Additional powers of 10 require the addition of another positional digit.

The distance between the two points pictured is d= Vn
katrin [286]

the distance between points is:

d = 7.8 units

 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)

 The ordered pairs are:

 (x1, y1) = (- 3, -2)

 (x2, y2) = (2,4)

 By applying the formula we have:

 d = root ((2 - (- 3)) ^ 2 + (4 - (- 2)) ^ 2)

 d = root (61)

 d = 7.8

Answers:

1.) 18 lemons
2.) 80 minutes

Explanation:

Porportions are a lot like fractions. For the first question, you can make the fraction 6/8, or 3/4 simplified. This means that for every 8 cups of water, you need 6 lemons.

Then, to find the amount of lemons you need if you have 24 cups of water, you need to think about what×8= 24. If we divide 24 by 8, we get 3, so if we multiply our fraction by 3/3, we should get the answer.

If we do 6/8 × 3/3, we get 18/24. This means that we need 18 lemons if we were to use 24 cups of water.

For the next question, our fraction 15/60, for 15 cakes baked in 60 minutes. Now we need to divide 20 cakes by 15.

This question is a little different from the first one because there will be a decimal involved. If we do 20/15, we get 1⅓. This means that this time, we will multiply 15/60 by (1⅓)/(1⅓).

If we multiply 60 by 1⅓, we get 80, which is the number of minutes needed to bake 20 cakes.

Hope this helps :)

Answer:

5\sqrt{8}

24\sqrt{3}

Step-by-step explanation:

To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

\sqrt{200}=\sqrt{25*8}  =\sqrt{25}*\sqrt{8}= 5*\sqrt{8}   =5\sqrt{8}

and

4\sqrt{108}=4\sqrt{27*4}  =4*\sqrt{27}*\sqrt{4}=4* \sqrt{9} *\sqrt{4}*\sqrt{3}    =4*3*2*\sqrt{3}=24\sqrt{3}
