There are 12 red marbles in a bag. The ratio of the total number of marbles in the bag to the number of red marbles in the bag is 5:2. How many marbles are in the bag?

Answer:

Step-by-step explanation:

slope (m) = 1

y-intercept (c) = - 1

Writing in slope intercept form

y = mx + c

y =  x - 1

Answer:

5 minutes

Explanation:

.5x + 2 = y

.2x + 3.8 = y

.5x + 2 = .2x + 3.8

-.2x         -.2x          

.3x + 2 = 3.8

      -2      -2          

.3x = 1.8

.3     .3

x = 5

After 5 minutes, both bikes will be at the same price.

Answer:

Step-by-step explanation:

[3x-2]÷4=2x-8

3x-2 = 4·(2x-8)

3x-2 = 8x-32

-2 = 5x-32

30 = 5x

x = 6

Answer:

(3x-2)/4= 2x-8  x=6

Step-by-step explanation:

(3x-2)/4 times 4= 2x-8

Multiply both sides by 4

3x-2/4 times 4= 2x  times 4-8 time 4

Simplify

3x= 8x = 8x-30-8x

Subtract 8x from both sides

3x-8x=8x-30-8x

Simplify

-5x=-30

Divide both sides by -5

-5x/-5 = -30/-5

Simplify so you get x=6

[tex]\large\boxed { \ ANS = \sqrt{5} }[/tex]

Step-by-step explanation:

Irrational numbers are numbers that cannot be written as simple fractions. All the numbers listed above except for [tex]\sqrt{5}[/tex] cannot be written as fractions.

• [tex]\frac{7}{3}[/tex] is already a fraction

• [tex]\frac{-9}{5}[/tex] is also already a fraction

• [tex]\sqrt{9}[/tex] is 3 and 3 can be written as [tex]\frac{3}{1}[/tex]

• [tex]\sqrt{5}[/tex]  is an irrational algebraic number and cannot be written as a simple fraction since it is equal to

Answer:

D. 12, 15, 25

Step-by-step explanation:

The triangle leg rule states that the smaller two lengths must add up to be greater than the largest length.

This means that the first two values must add up to be greater than the final value.

12 + 15 = 27

27 > 25

So, your answer is D

Step-by-step explanation:

The two quadrilaterals LMNR and PQNO are not similar. Timo tried to map one figure onto the other using rotation and dilation methods. He concluded that they are not similar because the rigid transformations like rotation preserve congruence and dilation will not change the shape but it changes its size. So, this results in no congruence.

Here Timo used rotation and dilation on the two quadrilaterals LMNR and PQNO. So, this resulted in a change in the size of the quadrilaterals. Because of this, Timo concluded that "it's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations, so the quadrilaterals are not similar".

Answer:

3 with the power of 2

Step-by-step explanation:

This is greater because when you multiply 3 by 3 you get 9, and when you multiply 2 x 2 x 2 you get 8

Answer:

See below.

Step-by-step explanation:

STEP 1:  If you write the given terms all with denominators of 16, they are 28/16, 25/16, 22/16, 19/16, __, ____, ____, 7/16, 4/16.

STEP 2: The terms decrease by 3/16 for each step.

RULE: Term 1 = 7/4 and term (n + 1) = term 'n' - 3/16

The operation for increasing by the same amount every step is addition.

The operation for decreasing by the same amount every step is subtraction.

STEP 3: The rule is that the terms decrease by 3/16 at each step.

So the next 3 terms after 19/16 will be 16/16, 13/16, and 10/16.

Reformat them and you have 1, 13/16, 5/8.

So now the completed sequence is 1&3/4, 1&9/16, 1&3/8, 1&3/16, 1, 13/16, 5/8, 7/16, 1/4.

Answer:

207400%

Step-by-step explanation:

Look at the decimal number 2074 as 2074 out of one. Furthermore, percent means per hundred. So the task is to convert 2074 out of one to 2074 out of one hundred.

The equation to solve the problem is displayed below where x is the 2074 as a percentage.

2074

Answer:

c.

Step-by-step explanation:

The solution is Option C.

Sample space is  set A = { blue , blue } , { blue , green } , { blue , red }

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the sample space be represented as set A

Now , the equation will be

The number of blue cars = 2 blue cars

The number of green cars = 1 green car

The number of red cars = 1 red car

So , the total number of cars = 2 + 1 + 1 = 4 cars

Now , Andy removes 2 race cars from the toy box without looking

Let the first removed car be a blue car

So , the second car can have any value including a blue , green or white

And , the sample space is given by set A

Set A = { blue , blue } , { blue , green } , { blue , red }

Hence , the set is { blue , blue } , { blue , green } , { blue , red }

Step-by-step explanation:

The formula for volume of a sphere is: [tex]\frac{4}{3} \pi r^{3}[/tex]. In this case, the radius is 12.3. 12.3 cubed is: 1860.867. 1860.867 x 4 is 7443.468. 7443.468 divided by 3 is 2481.156. Since we haven't multiplied by pi yet, the answer would be 2481.156[tex]\pi[/tex].
