Which fraction below represents a repeating decimal?

Answer:

x = 10; y = 6

Step-by-step explanation:

Let's list the factors of 60 because the product of those numbers is 60.

The following possibilities of x and y are possible using (x × y = 60):

Let's check each possibilities using the equation (x - y = 4):

Thus, the values of x and y are 10 and 6 respectively.

Step-by-step explanation:

f(-1) = 4(2)^-1 ≈ 4 × 1/2 = 2

(x, f(x)) = (-1, 2)

f(0) = 4(2)⁰ = 4×1 = 4

(x, f(x)) = (0, 4)

f(1) = 4(2)¹ = 4×2 = 8

(x, f(x)) = (1, 8)

f(2) = 4(2)² = 4×4 = 16

(x, f(x)) = (2, 16)

Step-by-step explanation:

Step-by-step explanation:

I never learned this (for good reasons, I say). for me this is the strangest thing in math. math is precise. we are not guessing around when we can actually calculate things.

this is definitely ok, when just trying to decide, if one fraction is larger than the other, but to use that for an actual operation among fractions, is the biggest nonsense I have ever seen in math lessons (and not simpler than doing the precise calculation). again, math is a precise thing. the only valid level of imprecise answers is rounding, but only for the end result, not for intermediate results, because the rounding errors are rarely compensating for each other, they mostly pile up making the end result even less precise.

enough with the venting ...

benchmark fractions are the simple fractions (and their multiples)

1 (=1/1), 1/2, 1/3, 1/4, 1/5, 1/6

and then in steps of 2 :

1/8, 1/10, 1/12, ...

we try to find the closest simple fractions to our actual fractions and use them to estimate the actual result.

the simplest (but also normally the least precise) benchmark approach is using 1/2 as benchmark unit and 0, 1/2, 1 as benchmarks.

so, is 10/12 closest to 0, to 1/2 or to 1 ?

we know that 0 in 12ths would be 0/12, 1/2 would be 6/12, and 1 would be 12/12.

so, out of these 3 values 10/12 is closest to 12/12 (=1), so that is what you are choosing as representation.

is 3/8 closest to 0, 1/2 or to 1 ?

we would have 0/8, 4/8, 8/8.

and 3/8 is closest to 4/8 (= 1/2), and that is what we are choosing here as representation.

and the estimated result of 10/12 - 3/8 = 1 - 1/2 = 1/2 or 4/8 or 6/12.

let's pick 1/4 as benchmark unit.

so, are the numbers closest to

0, 1/4, 2/4, 3/4 or 1 (4/4) ?

for 10/12 we get then

0/12, 3/12, 6/12, 9/12, 12/12

and 10/12 is closest to 9/12 (3/4), which we pick as representation.

for 3/8 we get

0/8, 2/8, 4/8, 6/8, 8/8

if equidistant, we have to round up, so, we get 4/8 (2/4), which we pick as representation.

and the estimated calculation is

10/12 - 3/8 = 3/4 - 2/4 = 1/4

which is really horrible ...

2 and 4 are factors of 12 and 8. all smaller benchmark fractions (<1/4; so, e.g. 1/5, 1/6, 1/8. ...) are not meeting that criteria, making the benchmark finding much harder. so, I would not try that.

the real result is

the LCM of 12 and 8 is 24 (2×12 and 3×8).

so, we have

20/24 - 9/24 = 11/24 (almost 1/2).

so, actually, the benchmark unit of 1/2 is giving the best result here.

but to just do the exercise of benchmark units that are not factors of both denominators, let's pick 1/6

so, are the numbers closest to

0, 1/6, 2/6, 3/6, 4/6, 5/6 or 1 (6/6) ?

for 10/12 we get (all nicely)

0/12, 2/12, 4/12, 6/12, 8/12, 10/12, 12/12

so, 10/12 is closest to 10/12 (of course) = 5/6, which we pick as representation.

for 3/8 we get (ugh, we have to go for 24ths here too as 4×6 and 3×8)

0/24, 4/24, 8/24, 12/24, 16/24, 20/24. 24/24

3/8 = 9/24

so, the closest number to 9/24 is 8/24 (= 2/6), which we pick as representation.

and the estimated calculation is

10/12 - 3/8 = 5/6 - 2/6 = 3/6 = 1/2

did I say already that I don't like this ? that I don't see the advantage to the actual calculation ?

so, just in case : I don't like this (ugh) !

Answer:

The total number of caramel apples are covered with sprinkles is 20 and this can be determined by using the arithmetic operations.

Step-by-step explanation:

Given :

Maya has 120 caramel apples to sell. Each caramel apple is covered with one topping.

1/5 of the caramel apples are covered with peanuts.

1/3 of the caramel apples are covered with chocolate chips.

3/10 of the caramel apples are covered with coconut. The rest are covered with sprinkles.

The following steps can be used in order to determine the total number of caramel apples are covered with sprinkles:

Step 1 - The arithmetic operations can be used in order to determine the total number of caramel apples are covered with sprinkles.

Step 2 - Let 'n' be the number of caramel apples are covered with sprinkles.

Step 3 - So, the value of 'n' is calculated as:

Step 4 - Simplify the above equation.

120 = 24 + 40 + 36 + n

n = 20

Answer:

There are 20 caramel apples that are covered with sprinkles.

Step-by-step explanation:

First we should make all of these have a common denominator. We could make these be 1/5 = 6/30, 1/3 = 10/30, 3/10 = 9/30. Now we can add them all up. 6 + 10 + 9 = 25/30. Now, to figure out how many apples is 1/30. 120 divided by 30 = 4. Now we can do 4x25 because that's how many non sprinkle apples there are. This is 100. 120 - 100 = 20. You could have also done 4x5 because there were 5/30 sprinkle apples, and gotten the same answer.

       so, there are 20 caramel apples that are covered with sprinkles.

The triangles ABC and EDC have corresponding sides

The triangles ABC and EDC are similar

The given parameters are:

ED = 8, DC = 10, EC = 12, AB = 12

BC = 15 and AC = 21

To determine that the triangles are similar, we simply divide the corresponding sides to determine the scale factor (k).

So, have:

k = AB/ED = BC/DC

This gives

k = 12/8  = 15/10

Evaluate the quotients

k = 1.5 = 1.5

The scale factors are equal

Hence, the triangles ABC and EDC are similar

Answer:

Choice C

Step-by-step explanation:

This is like a matching question. Here's what I mean by this. We know Triangle BCA and Triange JKL are congruent. So, what we have to do is match the side lengths together.

So the first side of BCA matches with JKL, the second side of BCA matches with JKL, the third side of BCA matches with JKL.

So first side:

BC is congruent  to JK

So second side:

CA is congruent  to KL

So third side:

JL is congruent  to BA

The third side is one of our answer choices.

That answer choice is C.

Answer:

257mm^2

Step-by-step explanation:

18*(3+15)/2 = 162

4*(15+5) =80

3+5 = 15

total = 257 mm^2

Answer:

Step-by-step explanation:

Area of composite figure:

Shape I:

Shape I is an triangle

base= 3 + 15 + 5 = 23 mm

height =  18 mm

[tex]\boxed{\text{Area of traingle = $\dfrac{1}{2}base*height$}}[/tex]

                          [tex]= \dfrac{1}{2}*18*23\\\\= 9*23\\\\= 207 \ mm^{2}[/tex]

Shape 2:

Shape 2 is an rectangle.

length = 15 + 5 = 20 mm

width = 4 mm

[tex]\boxed{\text{Area of rectangle = length * width}}[/tex]

                             = 20 *4

                             = 80 mm²

Shape 3:

length = 5 mm

widht = 3 mm

Area of shape 3 = 5 * 3 = 15 mm²

Area of the composite shape = 207 + 80 + 15

                                                   = 302 mm²
