Is 18/5 and 7/2 proportional

Answer:

11(7 + 4) = 11 × 7 + 11 × 4

Step-by-step explanation:

11(7 + 4) = _ x 7 + 11 x _

use distributive property:

11(7 + 4) = 7 x 11 + 7 x 11

Answer:

11 * 7 + 11 * 4

Step-by-step explanation:

given 11(7+4)

we need to use distributive property

To do so we multiply 11 by whats inside of the parenthesis

so 11(7+4) is equivalent to 11 * 7 + 11 * 4

Answer: Arithmetic (increasing by constant rate of 20)

Step-by-step explanation:

Arithmetic means the difference between two consecutive terms is constant which it is in this case because it constantly increases by a value of 20.

Geometric means the sequence is changing by a constant ratio or factor

Answer:

x = 110

y = 40

Step-by-step explanation:

m∡5 = 30° because it forms a linear pair with ∡6, which is 150°

x + y = 150  (angles 4 and 6 are alternate-interior and are congruent)

angles 3 and 6 are same-side interior and are supplementary

therefore:  x -2y = 180-150

if x + y = 150 we can say that x = 150 - y

we can plug '150-y' for 'x' in x - 2y = 30

150-y - 2y = 30

-3y = -120

y = 40

x = 110

Answer:

157.1 m

Step-by-step explanation:

Here, we want to calculate the length of the semi-circle

This simply refers to the circumference of the semi-circle

Mathematically, the circumference is half that of a full circle

The circumference of a full circle is;

C = pi * d

For half circle or semi-circle;

It is ;

C = (pi * d)/2

D = 50 m

The circumference is thus;

C = 50 * 3.142

C = 157.1 m

Answer:

1

Combine multiplied terms into a single fraction

6−8=12(4+5)

6−8=1(4+5)2

2

Multiply by 1

6−8=1(4+5)2

6−8=4+52

3

Add

8

888

to both sides of the equation

6−8=4+52

6−8+8=4+52+8

Answer:

[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]

Step-by-step explanation:

1) Use difference of squares: a² - b² = (a + b) (a - b).

[tex]( {x}^{2} - {3}^{2} )(3x + 2)[/tex]

2) Simplify 3² to 9.

[tex]( {x}^{2} - 9)(3x + 2)[/tex]

3) Use The FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]

Therefor, the answer is 3x³ + 2x² + -26x -18.

40 seconds

It will take 40seconds to both the lights to flash at the same time again.

" Least common multiple is defined as the smallest common multiple of the given set of numbers."

According to the question,

Given ,

Time to flash Light A is  every 8 seconds.

Time to flash Light B is every 20 seconds.

Condition given

Both the lights flash at the same time

Least common multiple (8, 20) = 40seconds

Light A flashes in

8seconds , 16seconds , 24seconds , 32seconds, 40seconds

Light B flashes in

20seconds , 40seconds

Hence, both the light flashes at the same time again is at 40seconds.

Step-by-step explanation:

Answer:

The blue line models the data points better than the red line. It is because the data points are all close to the line.

Answer and explanation:

The answer is actually -3. We already know f(x)/y is equal to 0, so the equation is then simplified to 0 = 2x - 6. You do inverse operation, so then -6 = 2x. Then -6 divided by 2 is -3. So -3 = x. Therefore, the zero of the function f(x) = 2x – 6 is -3.
