How does dividing mixed numbers compare with dividing fractions?

1 answer:

5 0

Mixed numbers are basically sometimes a sign of division. You need to turn the mixed number into an improper fraction.

Steps:

Multiply the whole number by the denominator of the fraction and then add that product to the numerator. Leave the denominator as it is before.

Example:

2 1/4

2x4=8

8+1= 9

Answer: 9/4

Then you can divide!

HELP PLS 25 POINTS!!!!

Anika [276]

Okay, let me first explain what the equation y = 8.77x + 686 means

y is the hikers elevation

Look at the graph and see what the y and x axis's are labeled as.

x is time.

8.77 is just the slop of the trend line.

686 is just the elevation the hiker starts at, or in technical terms, the y intercept. Y intercept is just where the lines touches the y axis.

The question asks what will be the hiker's elevation at 145 minutes.

To solve, just simply plug in 145 as X in the equation above. Remember x is time.

It will look like this :

y = 8.77 (145) + 686

Then solve.

y = 1271.65 + 686

y = 1957.65

Reminder: They want the nearest whole number!

Round 1957.65 feet to 1958 feet

What is the probability that a number selected at random from the set {2,3,7,12,15,22,72,108} will be divisible by both 2 and 3?

enot [183]

Answer: 3/8
There are only three numbers in there that 2 and 3 can go into evenly.

The probability that you will randomly select one of those numbers is 3/8.

A furniture store is having a sale on sofas and you're going to buy one. The advertisers know that buyers get to the store and t

MrRissso [65]

Answer:

$290

Step-by-step explanation:

We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.

Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.

Thus;

P(x) for expensive sofa = 1/5

P(x) for sofa in sale advertisement = 4/5

Thus, expected value is;

E(X) = (1/5)450 + (4/5)250

E(x) = 90 + 200

E(x) = $290

URGENT!! A student needs 3 pieces of wire for a science project. The second piece must be 3 times as long as the first. The thir

Marianna [84]

Answer:

Part a) The inequality that represent the situation is

$x+(3x)+(6x) \leq 350\ in$

Part b) The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$

Step-by-step explanation:

Let

x------> the length of the first wire

3x---> the length of the second wire

2(3x)=6x -----> the length of the third wire

Part a) WRITE AN *INEQUALITY* THAT MODELS THE SITUATION

we know that

The inequality that represent the situation is

$x+(3x)+(6x) \leq 350$

Part b) WHAT ARE THE POSSIBLE LENGTHS OF THE SHORTEST PIECE OF WIRE?

we know that

The shortest piece of wire is the first wire

Solve the inequality

$x+(3x)+(6x) \leq 350$

$10x \leq 350$

$x \leq 35\ in$

The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$
