estimate 21.9 divided by 3

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Answer:

He forgot to flip the second fraction.

Step-by-step explanation:

He has:

−8/9 ÷ 9/8 = −8/9 × 9/8 = −72/72 = −1

He made a mistake. When you change a division to a multiplication, you must use the reciprocal of the second fraction. You have to flipt the second fraction. He did not flip it.

This is correct:

−8/9 ÷ 9/8 = −8/9 × 8/9 = −64/81

Answer:

\( - 2 \frac{3}{5} \div \frac{3}{5} = - \frac{13}{5} \times \frac{5}{3} = - \frac{13}{3} = - 4 \frac{1}{3} \)

\(2 \frac{1}{4} \div \frac{3}{4} = \frac{9}{4} \times \frac{4}{3} = 3\)

\( - \frac{10}{17} \div ( - \frac{15}{17} ) =\)

\( - \frac{10}{17} \times ( - \frac{17}{15} ) = \frac{2}{3} \)

\( 2.75 \div ( - 2.2) = \)

\( 2 \frac{3}{4} \div ( - 2 \frac{1}{5} ) = \)

\( \frac{11}{4} \div ( - \frac{11}{5} ) = \frac{11}{4} \times ( - \frac{5}{11} ) = - \frac{5}{4} = - 1.25\)

3 ⇒ 2 (1/4) / (3/4)

-1.25 ⇒ 2.75 / (-2.2)

2/3 ⇒ (-10/17) / (-15/17)

-4 1/3 ⇒ -2 (3/5) / (3/5)

Hope my answer helps you✌️

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14.  And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.

Answer:

a) If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.

b) If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.

c) If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².

Step-by-step explanation:

a) To solve, set up a proportion. Volume is three-dimensional, so we need to cube.

(7/8)³=1029/x

Now we can solve using cross products to get 1536.

If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.

b) To solve the second one, we also set up a proportion. Height is one-dimensional, so we will not need exponents here.

7/8=14/x

Solve using cross products to get 16.

If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.

c) Now we are solving for area, which is two-dimensional. Therefore, we will need to square.

7/8²=392/x

Solve using cross products to get 512.

If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Answer:

See below

Step-by-step explanation:

We can see that the thick line which outlines the main cable, the base and tower form a triangle

The longest length is the main cable which is 15m

If it is indeed a right triangle. the squares of the sums of the two shorter sides must equal the square of the longer side.

Sum of squares of shorter sides(also called legs) = 9² + 12²

= 81 + 144

= 225

Square of the longer side = 15² = 225

Since 15² = 9² + 12²

the triangle shown is indeed a right triangle with hypotenuse = 15m and the legs of the right triangle  9m and 12m

Answer:

1.) 4 Carriers

2.) 12 boxes

3.) 2 r1 or 2.5

Step-by-step explanation:

1.) 8X = 30

We get the equation 8X = 30 from the fact that there are 8 calculators in each carrier and there are X to hold the 30 calculators.

X = 30/8 = 3.75 = 4 carriers because we can't have portions of carriers

2.) 3X = 34

We get the equation 3X = 34 from the fact that there are 3 toys in each box and there are a total of X boxes to hold the 34 toys.

X = 34/3 = 11.3333 = 12 boxes because we can't have a third of a box
