Answer:

2.4 or 2 $\frac{2}{5}$

Step-by-step explanation:

Let's set this up:

We have 3/1 $\frac{1}{4}$

That's also 3/1.25

For division, we don't divide if there is a fraction, so we move the decimal place over to the right for <em>both the numbers</em>

300/125

Then you long divide as normal:

And it's really hard to show how to long divide on a computer so I'm just going to go ahead and assume you know how to.

But the answer to that would be 2.4 or 2 $\frac{2}{5}$

Thank you, let me know if you have any questions.

It WILL BE 12/5

3 is 12/4

1 1/4 is 5/4

When you set it up like this 12/4 * 4/5 you can cancel out the 4’s and get 12/5 as the final answer.

Rahul has 5 BLUE BLOCKS, 3 PINK BLOCKS AND 4 GREEN BLOCKS. He wants to count the total number of blocks he is having. In how man

arsen [322]

Answer:

a) He can find the answer in one way

b) We make use of Addition property of mathematics

c) Total number of blocks = 12 blocks

Step-by-step explanation:

a) He can find the answer in one way

b) We make used of addition property of mathematics

c) The total number of blocks he is having is calculated as:

Blue blocks + Pink blocks + Green blocks

Where

Blue blocks = 5

Pink blocks = 3

Green blocks = 4

Hence:

Total number of blocks = 5 + 3 + 4 = 12 block

Which corresponds to the perimeter of triangle ABC?

____ [38]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

A (-5 , -1)

B (-2, 3)

C (6, -3)

Perimeter = ?

Formula

$d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }$

distance AB $d = \sqrt{(-2 + 5)^{2} + (3 + 1)^{2} }$

$d = \sqrt{(3)^{2} + (4)^{2} }$

$d = \sqrt{(9 + (16) }$

$d = \sqrt{25}$

d = 5

Distance BC $d = \sqrt{(-3 - 3)^{2} + (6 + 2)^{2} }$

$d = \sqrt{(-6)^{2} + (8)^{2} }$

$d = \sqrt{36 + 64}$

$d = \sqrt{100}$

d = 10

Distance AC $d = \sqrt{(-3 + 1)^{2} + (6 + 5)^{2} }$

$d = \sqrt{(-2)^{2} + (11)^{2} }$

$d = \sqrt{4 + 121}$

$d = \sqrt{125}$

d = 11.2

Perimeter = 5 + 10 + 11.2

= 15 + $\sqrt{125}$

X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4

Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.

What is 10x+7=147;14,15,16

gizmo_the_mogwai [7]

$10x + 7 = 147$
1st step you subtract 7 from both sides and the 7 get cancelled so you will get
$10x = 140$
2nd step you divide by 10 from both sides so you will get

$x = 14$

3rd step is that you final answer is
$x = 14$

The probability of Elizabeth winning the soccer game is 0.72. What is the probability of not winning the game?

Rom4ik [11]

Answer:

.28 = P( not winning)

Step-by-step explanation:

The probability of winning is .72

The 2 possibilitites are winning and not winning. They must total 1

1 = P(winning) +P( not winning)

1 = .72 + P( not winning)

Subtract .72 from each side

1-.72 = P( not winning)

.28 = P( not winning)
