Answer:

5 4/9

Step-by-step explanation:

our equation is 4 2/3+7/9

2/3=6/9.

So we have 4 6/9+7/9

Simplify:

4 13/9

5 4/9

Part (a)

4, read it off the diagram.

Part (b)

(4 in)(1 ft/12 in) = 1/3 ft

Part (c)

(60 ft)(20 ft)(1/3 ft)=400 cu ft

Part (d)

(66 ft)(26 ft)(1/3 ft)=572 cu ft

Part (e)

572 cu ft - 400 cu ft = 172 cu ft

well, we can simply divide 210 by (3 + 4) and then distribute accordingly

Answer:

James- 90 and John- 120

Step-by-step explanation:

Since you want to divide 210 with a ratio of 3:4. It's easiest to first add your 3 and 4. This =7. Now you know you have to divide 210 by 7 before you give them to James and John. 210 divided by 7 = 30. Now do 30 times each ratio.

James has 30 x 3 and John has 30 x 4

this leaves you with 90 and 120

The statement that least-squares solution of a x = b is the vector in the column space of a closest to b  is; true

One  method for computing a least-squares solution of Ax = b is;

Now, If b is in the column space of A then it tells us that there is at least one exact solution to the system Ax = b. In this case, it means that every solution to the system minimizes |Ax − b| (makes it zero) and as such  is a least squares solution.

The ratio of the area of the two squares is 9:16.

A square has four corners and is a closed, two-dimensional (2D) object. A square has equal and parallel sides on all four sides.

A square is a closed object with four sides that are all the same length, and its interior angles are all 90 degrees. A square can have many different characteristics. The following list includes some of a square's key characteristics.

If it is square:

The ratios of the sides of two squares = 3:4

Let the common multiple of the above ratio be x.

So, side of one square = 3x

and side of the other square = 4x

Area of square = (side)²

Area of square with side 3x = (3x)² = 9x²

Area of square with side 4x = (4x)²= 16x²

Ratio of the areas of the two squares = Area of square with side 3x/Area of square with side 4x = 9x²/16x² = 9/16 = 9:16

Therefore, the ratio of the area of the two squares is 9:16.

The correct dividend of 76 is required to yeild a quotient of 25 and a remainder of 1 when divided by 3.

We can know the dividend, the quotient and the remainder of the division using the division formula: (Divisor x Quotient) + Remainder = Dividend

Divisor = 3

Quotient = 25

Remainder = 1

(3 × 25) + 1 = 75 + 1

The required percentage change in the number of teen births between 2000 and 2015 is 52.5%.

Given that,
In 2000, there were 47,000 teen births in the United States. In 2015, there were 22,300 teenage births. The percent change in the number of teen births between 2000 and 2015 is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Number of teens in the year 2000 = 47,000
Number of teens in the year 2015 = 22300
Percentage change = 47000-22300/47000 × 100 = 52.5%

Thus, the required percentage change in the number of teen births between 2000 and 2015 is 52.5%.
