Answer 1

Answer: This is simple.

= $3(3)/(5)$ ÷ $4(1)/(2)$
change the mixed fractions to improper ones.
$(18)/(5)$ ÷ $(9)/(2)$
Multiply $(18)/(5)$ by the reciprocal of $(9)/(2)$ which is $(2)/(9)$

= $(18)/(5)$ × $(2)/(9)$
= $(36)/(45)$

Since it can be simplified further, we get the answer
$(4)/(5)$

How?
There is a common multiple 9
$(36/9)/(45/9)$
= $(4)/(5)$
Answer= B. $(4)/(5)$

There are 4 queens in a standard deck of 52 CARDS. You pick one card at random. What is the probablity of not picking a queen?

Answers

Find the number of cards that are not queens by subtracting 4 from 52, which equals 48. So 48 cards out of 52 cards are not queens. This can be written as 48/52. Simplify this fraction. (48/4 / 52/4) = 12/13. The probability of not picking a queen is 12/13. Another, simpler, way to solve it is this: if you know there are 13 suites in a deck of cards, excluding one suite, in this case queens, will give you 12 out of 13 suites left that are not that suite.

48/5224/2612/13So the probability of not choosing a queen is 12/13

7 copies of the sum of 8 fifths and 4

Answers

Answer:

39.2

Step-by-step explanation:

We need to find the solution of 7 copies of sum of 8 fifths and 4.

Now, 8 fifths = $(8)/(5)$

Then, sum of 8 fifths and 4 = $(8)/(5)+4$ = $(28)/(5)$

Now, 7 copies of $(28)/(5)$ means that we meed to multiply $(28)/(5)$ 7 times

i.e. 7 copies = $7* (28)/(5)$

i.e. 7 copies = $(196)/(5)$

i.e. 7 copies = 39.2

Hence, 7 copies of sum of 8 fifths and 4 is 39.2

39¹/₅ or 39.2

Further explanation

The Problem:

7 copies of the sum of 8 fifths and 4.
Write an expression to match, and then evaluate.

The Process:

Here are some early expressions that need attention.

8 fifths is $\boxed{(8)/(5)}$
the sum of 8 fifths and 4 is $\boxed{(8)/(5) + 4}$

7 copies of the sum of 8 fifths and 4 mean that we have to multiply 7 with the sum of 8 fifths and 4. The term of "the product" is synonymous with multiplication.

Let us write an expression to match for '7 copies of the sum of 8 fifths and 4'.

$\boxed{\boxed{ \ 7 * \bigg((8)/(5) + 4 \bigg) \ }}$

Let us calculate the operation in parentheses at first.

$\boxed{ \ (8)/(5) + 4 \ }$

$\boxed{ \ (8)/(5) + (20)/(5) \ }$

$\boxed{ \ (28)/(5) \ }$

And now we solve the full expression.

$\boxed{ \ = 7 * \bigg((8)/(5) + 4 \bigg) \ }$

$\boxed{ \ = 7 * (28)/(5) \ }$

$\boxed{\boxed{ \ (196)/(5) \ }}$

In mixed fraction:

$\boxed{ \ (196)/(5) = \ ? \ }$

$\boxed{ \ = (195)/(5) + (1)/(5) \ }$

$\boxed{ \ = 39 + (1)/(5) \ }$

$\boxed{\boxed{ \ 39(1)/(5) \ }}$

In decimal:

$\boxed{ \ 39(1)/(5) = \ ? \ }$

$\boxed{ \ = 39(1 * 2)/(5 * 2) \ }$

$\boxed{ \ = 39(2)/(10) \ }$

$\boxed{\boxed{ \ 39.2 \ }}$

Thus, the result is $\boxed{\boxed{ \ 39(1)/(5) \ or \ 39.2 \ }}$ .

Elena bought 320 tropical fish for a museum display. She bought 7 times as many triggerfish as parrotfish. How many of each type of fish did she buy?

Which is a system of equations to model the problem if x represents the number of parrotfish Elena bought and y represents the number of triggerfish she bought?

A.
x + y = 320
y = 7x

B.
x + 7y = 320
y = 7x

C.
x – y = 320
y = 7x

D.
x + y = 7
y = 320x

2. Michael and Kathryn bowl together and their combined total score for one game was 425 points. Michael’s score was 70 less than twice Kathryn’s. What were their scores?

Which is a system of equations to model the problem if x represents Kathryn’s score and y represents Michael’s score?

A.
x + y = 70
y = 2x – 425

B.
x – y = 425
y = 2x – 70

C.
x + y = 425
y = 2x – 70

D.
x + y = 425
y = 2x + 70

5.A collection of quarters and dimes is worth $12.40. There are 67 coins in all.

How many of each coin are there?

quarters.___?_____
dimes.___?____

Answers

1. A.
x parrot fish + y triggerfish = 320 total fish.
y = 7x shows that there are 7 times as many triggerfish.
2. C
x + y shows a total score of 425.
y = 2x - 70 shows that Michael's score, y, is 70 less (minus) than twice Kathryn's
3. write two equations
x + y = 27 total feet
2x + 3 = y
Substitute 2x + 3 for y in the first equation
x + (2x + 3) = 27
3x + 3 = 27
3x = 24
x = 8
Substitute 8 in to either equation to find the other length.
8 + y = 27
y = 19
The shorter piece is 8 and the longer piece is 19
4. x + y = 3200 people -> y = 3200-x
8x + 12y = 33,040 dollars
8x + 12(3200 - x) = 33040
8x + 38400 - 12x = 33040
-4x = -5360
x = 1340 (1340 children)
1340 + y = 3200
y = 1860 adults
5. I don't think the numbers for this were put in correctly because I get a decimal and a negative number when I solve for it but hopefully if you do get the correct cost/amount of coins you will understand this well enough to do it on your own. Hope I helped!
