WITCHER [35]

Answer:

Money made by you =$55

Money made by your friend = $33

Step-by-step explanation:

Given:

The ratio of the amount of money you make to the amount of money your friend makes = 5:3

The total amount made = $88

To find money made by each of them using tape diagrams.

Solution:

The tape diagram for the given situation is shown below.

Money mad by you is represented by 5 rectangles

Money mad by your friend is represented by 3 rectangles

Total number of rectangles = $5+3$ = 8

Thus, 8 rectangle represent a total of $88.

We have

$8\ rectangles =\$88$

Dividing both sides by 8, we have:

$\frac{8}{8}\ rectangles =\$\frac{88}{8}$

$1\ rectangle =\$11$

So, money made by you will be:

$5\ rectangles =5\times \$11=\$55$

Money made by your friend will be:

$3\ rectangle =3\times \$11=\$33$

Scarllet selects a card at random from a deck that contains 18 red 12 yellow and 20 blue cards what is the probablity that she d

Romashka [77]

Answer:

18/25

Step-by-step explanation:

Probability is number of outcomes of interest/total number of outcomes

This said we can first find the number of outcomes of interest.

This means the number of cards that are not red.

12+20=32

There are 32 non red cards.

Next we find the total number of outcomes. This is the total number of cards.

18+12+20=50

So the probability that she does not select a red card is 32/50

We can simpify that by dividing both the numerator and denominator by 2.

Help please, i can't do this math problem

P= -1/6

You need to combine all like terms on each side first. -5p+14=16+7p Then you get all the same terms on each side by inverse operation. -2=12p Then you do the inverse operation by dividing both sides by 12.
