Answer:

See Explanation

Step-by-step explanation:

Given

Red:Blue = 2 : 3

Required

Determine the possible number of blue and red marbles

This question requires options. Since none were given, I'll answer on a general term.

To get the possible amount of each marble, we simply multiply the ratio by the same factor.

Take for instance.

Multiply ratio by 15

Red:Blue = 2 : 3

Red:Blue = 2 *15: 3*15

Red:Blue = 30: 45

This means that:

Red = 30 and Blue = 45

Another possible amount is: <em>multiply by 10</em>

Red:Blue = 2 : 3

Red:Blue = 2 *10: 3*10

Red:Blue = 20: 30

This means that:

Red = 20 and Blue = 30

<em>So, all you need to do is to multiply by the same factor</em>

Answer:

80*

80*

75*

120*

Step-by-step explanation:

both angle 1 and 2 for the first image have the same value as  the other angle of 80* because it is a set of parallel lines and one line going through it.

1 on the next set of images is 75* because is is an alternate exterior angle.

2 of the last set of images is 120* because it is same side interior angles.

-5= s<br> —<br> 18<br> Someone help please I’m stuck
Vlad1618 [11]

-5=s/18

Pretend that s/18 is 1/18s

-5=1/18s

Multiply by 18/1 for both sides

-5(18/1)=1/18(18/1)s

Cross out 1 and 1, divide by 1 and then is one.

Cross out 18 and 18, divide by 18 and then is one.

s=-90

Answer: s=-90

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).
Anastaziya [24]
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36

Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.

Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x

FIND THE SUM OF 20 TERMS OF THE ARITHMETIC SERIES IN WHICH 3rd TERM IS 7 AND 7th TERM IS 2 MORE THAN THREE TIMES ITS 3rd TERM
algol13

Answer:

740

Step-by-step explanation:

The n th term of an arithmetic series is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₃ = 7 and a₇ = (3 × 7) + 2 = 21 + 2 = 23 , then

a₁ + 2d = 7 → (1)

a₁ + 6d = 23 → (2)

Subtract (1) from (2) term by term

4d = 16 ( divide both sides by 4 )

d = 4

Substitute d = 4 into (1)

a₁ + 2(4) = 7

a₁ + 8 = 7 ( subtract 8 from both sides )

a₁ = - 1

The sum to n terms of an arithmetic series is

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ] , thus

S_{20} = \frac{20}{2} [ (2 × - 1) + (19 × 4) ]

     = 10(- 2 + 76) = 10 × 74 = 740
