Answer:

Given - 1/3 + 2/6

To find - Answer of this

Solution -

1/3 + 2/6

To solve the fraction we need to equalize the denominators,

Taking LCM of the denominators

LCM of 3 and 6 is 6

= 1/3× 2/2 + 2/6× 1/1

= 1 × 2/ 3 × 2 + 2 × 1/6 × 1

= 2 /6 + 2/6

= 2 + 2/6

= 4/6

= 2/3

Alternative method -

1/3 + 2/6

1/3 + 1/3 ( 2/6 on simplifying)

1 + 1/3

2/3

Jon's coin collection consists of quarters, dimes and nickels. If the ratio of quarters to dimes is 5:2, and the ratio of dimes

Margarita [4]

Answer:

The ratio of quarters to nickels is:

15:8

Step-by-step explanation:

To solve the exercise, you must first consider how big is the ratio of each one to the other, when it is mentioned that the ratio of quarters to dimes is 5:2 it means that for every 5 quarters, Jon has 2 dimes, for the more quarters there are with respect to the dimes, we simply divide the larger value by the smaller:

5/2 = 2.5

Thus, we know that there are 2.5 more quarters than dimes. Now the following proportion: the ratio of dimes to nickels is 3:4, which means that for every 3 dimes there are 4 nickels, as the nickels are greater in quantity, we are going to see how many times they are greater in proportion than the dimes making again a division of the major over the minor:

4/3 = 1.33333333333 (we are going to use the fractional number so as not to lose decimals).

As we can see, the nickels are a little more than 1 with respect to the dimes, now we are going to create two formulas with those values:

q = 2.5d
n = 4/3 d

Where:

q = quarters
d = dimes
n = nickels

As you see. We only express the calculated proportions, at first glance you can identify that the number of quarters is greater, but to know how much greater with respect to nickels we are going to divide the two values that accompany "d" in the formulas:

2.5 / (4/3) = 15/8

If we express it in ratio as it is in the exercise, we obtain:

15:8

So, 15:8 is the ratio of quarters to nickels, which means that for every 15 quarters, jon has 8 nickels.

20 points! Identify the solids that form the compos

Troyanec [42]

The composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.

The composite solid's surface area is 225.4 square inches.

Step-by-step explanation:

Step 1:

The given composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.

The surface area of the composite shape is given by summing the individual surface areas.

The composite shape's surface area = The cube's surface area + the cylinder's surface area.

Step 2:

Any cube's surface area is calculated by multiplying 6 with the square of the side length ( $a^2$ ).

The cube's surface area = $6a^2$ = $6(5^{2} )$ = $150$ square inches.

Step 3:

Any cylinder's surface area is calculated with the following formula;

The cylinder's surface area = $2 \pi r h+2 \pi r^{2}$ = $2 \pi (2) (4)+2 \pi (2)^{2}$ = $75.398$ square inches

Step 4:

The composite shape's surface area = The cube's surface area + the cylinder's surface area.

The composite shape's surface area = 150 + 75.398 = 225.398 square inches. Rounding this off, we get the area as 225.4 square inches.

What is the coefficient for 5x + 3 = 18

erik [133]

Answer: 5

Step-by-step explanation: Let's go over a little algebra terminology.

The number in front of your variable is called your coefficient and a variable is just a letter that represents any number.

So here, your coefficient is 5 since it appears in front of the variable, x.
