Answer:

5.29

Step-by-step explanation:

1. Set up the equation 2.3x2.3 on top of eachother like so,

[tex]2.3\\ x2.3[/tex]

We will be working right to left.

2. Then we must create the first line of numbers.

a. Mulitply 3x3=9

b. Multiply 3x2=6

This makes the  first line of numbers 69.

3. For the second line of number do much of the same.

a. First add a zero under 9 to offset this new line.

b. Then multiply 2x3=6

c. Then 2x2=4

4. Finally add the two number together.

[tex]69+460=5.29[/tex]

5. Count up the decimal places in both factors combined, then moved the decimal sign left that many times.

This will result in our answer 5.29.

Step-by-step explanation:

what do we need to do ?

just solve the system of 2 equations ?

as we have x and -x in the equations, we simply add both equations, get one summary equation just in y, solve for y, and then use one of the original equations to solve for x :

y = x - 4

y = -x + 2

----------------

2y = 0 - 2

2y = -2

y = -1

-1 = x - 4

3 = x

x = 3

y = -1

4x + 3x= 7x

7x is the total sq.cm which is 300

7x= 300

x= 300/7

= 42.8

length= 4x

= 4 × 42.8

= 171.42

breadth= 3x

= 3 × 42.8

= 128.4

Answer:

Step-by-step explanation:

Since both AC and DB are diameters, angle 3 is central angle.

Angles 1 and 3 are vertical angles, hence are of equal value.

Since the central angle has same value as the intercepted arc, we have:

Correct choice is A

As

m<3 is opposite to m<1 both the angles are equal

Now

m<3=m<1

He recieved 8 ticket (even number) per day for 7 days. 8×7=56

56 tickets ÷ 7 days

would equal to him receiving 8 tickets every one of the 7 days.

The equation that can be used to find how many hours, h, it will take to drive m miles at her constant speed = m/65 = h.

Speed is defined as the rate at which an object moves from one place to another with respect to time.

The formula for speed = distance (m)/time (h)

The speed = 65miles/ h

The distance = m

The time = h

To find the time, make h the subject of formula;

h(time) = distance (m)/speed (65)

h = m/65.

Answer:

B) 2.8 with line on top

Step-by-step explanation:

Here I will show you step-by-step with detailed explanation how to calculate 26 divided by 9 using long division.

Before you continue, note that in the problem 26 divided by 9, the numbers are defined as follows:

26 = dividend

9 = divisor

Step 1:

Start by setting it up with the divisor 9 on the left side and the dividend 26 on the right side like this:

[tex]\sqrt[9]{26}[/tex]

Step 2:

The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

[tex]\\ \sqrt[9]{26} ^0[/tex]

Step 3:

Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.

       0    

   9 ⟌ 2 6  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

       0    

   9 ⟌ 2 6  

     - 0    

       2    

Step 5:

Move down the 2nd digit of the dividend (6) like this:

       0    

   9 ⟌ 2 6  

     - 0    

       2 6  

Step 6:

The divisor (9) goes into the bottom number (26), 2 time(s). Therefore, put 2 on top:

       0 2  

   9 ⟌ 2 6  

     - 0    

       2 6  

Step 7:

Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:

       0 2  

   9 ⟌ 2 6  

     - 0    

       2 6  

      1 8  

Step 8:

Subtract the result in the previous step from the number written above it. (26 - 18 = 8) and write the answer at the bottom.

       0 2  

   9 ⟌ 2 6  

     - 0    

       2 6  

     - 1 8  

         8  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 26 divided by 9 calculated using Long Division is:

Answer: 5 3/4

Step-by-step explanation:

Answer:

41.13 sq m

Step-by-step explanation:

area of square = 4² = 16

there are two quarter-circles which equals one semicircle

area of semi-circle is πr²/2

A = 4²π/2 = 8π = 25.13

add together: 16 + 25.13 = 41.13

Answer:

41.13m

Step-by-step explanation:

To find the area of a circle, use A= πr²

A(of circle) = π * 4²

A(of circle) = π * 16

A(of circle) ≈ 50.2655

Because you only have 2 quarters of a circle, you multiply it by 2/4

A(of 2/4 circle) ≈ 25.13275

A of rectangle = l * w

A(of rectangle) = 4 * 4

A(of rectangle) = 16

16+25.13275 = 41.13275

or 41.13
