10 cm 8 cm 14 cm 7 cm 6 cm 15 cm What is the total area of the figure ?

A 373cm2
B 338cm2
C 303cm2
D 268cm2

Answer:

w+6=8 and w=2

Step-by-step explanation:

2(w+6) = 16

divide by two on both sides to remove the 2

w+6=16/2

w+6=8

  -6 (remove six from both sides)

w=2

Answer:

Answer is D. 75 cm2

Answer:

5

Step-by-step explanation:

In the case when we multiplied 0.014 by 100,000 so it comes

= 0.014 × 100,000

= 1,400

Since The value 0.014 were times by 5 zeros.

Therefore the decimal point would move 5 places to the right

Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

The together rate is the sum of each separate rate.

In this problem, the rates are:

Hence, applying the equation for the together rate:

[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]

[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]

[tex]2x + 6 = 3x[/tex]

[tex]x = 6[/tex]

It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

Answer:

The answer is 4

Step-by-step explanation:

You just divide 80 by 15.

She can jump rope 20 times in 15 seconds

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that Jen can jump rope 80 times in 60 seconds.

We have to determine the number of jumps can she make in 15 seconds.

Let the number of jumps would be x she can make in 15 seconds

Since she jumps at a constant ratio of seconds to jumps

So according to proportionality,

⇒ 80/60 = x/15

⇒ x = 15(80/60)

⇒ x = 20

Hence, she can jump rope 20 times in 15 seconds.

Answer: 9 and 8?

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

= f (x) = -2 log 4 (x + 5) - 4

= 4 (-2 + 5) - 4

= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3

= So now you have 4 (3) - 4

= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.

= 4 (3) which is the same as 4 × 3 which is 12.

= then you do 12 - 4 which is 8.

= 8 is your answer.

Step-by-step explanation:

Answer:

11. A) 12

12. D)11

Step-by-step explanation:

11. We substitute x with 12 in 3(x)-11.

3(12)-11=

36-11= 25

We substitute x with 12 for the second equation (x+13).

12+13=25

Both answers match so the answer for #11 is 12.

12.We substitute x with 11 in 4(x)-4.

4(11)-4=

44-4=40

We substitute x with 11 for the second equation (2(x)+18)

2(11)+18=

22+18=40

Both answers match so the answer for #12 is 11.

Step-by-step explanation:

To find - How can you determine the number of solutions of a system

              of linear equations by inspecting its equations?

Proof -

There exists three types of solution for a system of linear equations.

1. No solution.

2. Unique solution.

3. Infinite many solutions.

Now,

Let the 2 linear equations are as follows :

y = ax + b

y = cx + d

1. For no solution -

a = c and b ≠d

For example-

y = -2x + 5

y = -2x  - 1

Subtract first equation from second , we get

y - y = -2x - 1 - ( -2x + 5)

⇒0 = -2x - 1 + 2x - 5

⇒0 = -6

Not possible

So, There exist no solution.

2. For unique solution -

a ≠ c and b , d can be any value

For example -

If b and d are same ,

y = 2x - 4

y = -3x - 4

Subtract equation 1st from 2nd , we get

y - y = -3x - 4 - ( 2x - 4)

⇒0 = -3x - 4 - 2x + 4

⇒0 = -5x

⇒x = 0

⇒y = 2(0) - 4 = -4

∴ we get

x = 0, y = -4

If b and d are different

y = 2x - 4

y = -3x + 5

Subtract equation 1st from second

y - y = -3x + 5 - 2x + 4

⇒0 = -5x + 9

⇒-5x = -9

⇒x = [tex]\frac{9}{5}[/tex]

⇒y =2([tex]\frac{9}{5}[/tex]) - 4 = [tex]\frac{18}{5} - 4 = \frac{18 - 20}{5} = -\frac{2}{5}[/tex]

∴ we get

x = [tex]\frac{9}{5}[/tex] , y = [tex]-\frac{2}{5}[/tex]

3. Infinitely many solution -

a = c and b = d

For example -

y = -4x + 1

y = -4x + 1

Subtract equation first from equation second

y - y = -4x + 1 - ( -4x + 1)

⇒0 = -4x + 1 + 4x - 1

⇒0 = 0

Satisfied

So, Infinite many solution possible.

For the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The figures are given in the picture:

For the red figure: Translate 1 unit down then 3 units left.

For the yellow figure: translate 5 units down and then 2 units right

For the blue figure: Reflect the figure at the y-axis.

Answer:

It would be 10 units

you can use the midpoint formula.

Step-by-step explanation:

dn means the difference (meaning what do you add/subtract to get the next number)

T0 means the term before the first one you got.

Tn = dn + T0

Tn = 2n + 0

Therefore our equation will be

Tn = 2n

Answer:

t is a regular hexagon of side 2′. So it can be divided into 6 triangles equal in all respects.The sum of all interior angle of hexagon =(n-2)*180 = (6–2)180 =720 deg. each interior angle =720/6 =120 deg.Side of the triangle divides this angle into two equal halves each = 60 deg.when two base angles of each triangle are 60 and 60 third angle will also become 60 making it as equilateral triangle. N ow the area of hexagon =6*the area of each equilateral triangle of base 2 ft.=6*1/2*2*h. h is the altitude of the triangle=2/2*tan 60 = rt3 =1.732 .NOW area of hexagon =6*1.732 = 10.392 sq.ft
