Answers

The number of the blue leashes will be 240.

What are linear equations?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

It is given that:-

A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.

The number of the blue leashes will be calculated as:-

L     =    320

B   +    P   +   g   =   320

{ (320  x   0.3 ) } + 0.7 ( B  +  g ) =  320

( 96 )  +   ( 2.8g )   =   320

2.8g   =   320 / 96

g   =   222  /  2.8  =  80

Now  B  =   3  x  g

B   =   3   x   80

B   =   240

Therefore the number of the blue leashes will be 240.

What is the sales tax on a refrigerator priced $1269, if the sales tax rate is 6.7%?

Answers

Answer:

sales tax: $85.023

Explanation:

Original or actual price is always of 100%

Solving:

100% = $1269

Find the unit percent :

1% = $(1269/100) = $12.69

Find the sales tax :

$12.69 × 6.7 = $85.023

$1269 X 0.067 (6.7% : 100) = 85.023

Answers

Answer: 6 more games

Step-by-step explanation:

Let’s review what we know:

The red team’s probability of winning is 70% (0.7).The blue team’s probability of winning is 65% (0.65).There are a total of 120 games.


To find the amount of games each team will statistically win, we multiply the percentage by the number of games.


Red Team: 0.7 x 120 = 84 games.

Blue Team: 0.65 x 120 = 78 games.


84 - 78 = 6 games.
Therefore, the red team will statically win 6 more games than the blue team.

Answer: A=9

Step-by-step explanation:

The equation for this table is x+16 =Y.

To solve for Y, we must plug in. (in other words, substitute the letters with (known) numbers).

A is in the 3rd row under the Y column. Hence, we will use the X value found in the same row, which is 3.

A= x+16

The bar graph shows the results of spinning a spinner 100 times. Use the bar graph to find the experimental probability of not spinning a 5.
PLEASE QUICK

Answers

Answer:

81%

Step-by-step explanation:

1.

We know that the probability of spinning a five is 19% since:

19/100 = 0.19 = 19%

However, we are looking for the probability of NOT spinning a five.  So, we will have to find the probability sum of the remaining numbers (1, 2, 3 and 4).

2.

- The probability of spinning a one is 20% since:

20/100 = 0.2 = 20%

- The probability of spinning a two is 18% since:

18/100 = 0.18 = 18%

- The probability of spinning a three is 22% since:

22/100 = 0.22 = 22%

- The probability of spinning a four is 21% since:

21/100 = 0.21 = 21%

3.

Now we will add all of these probabilities together to find the total probability of NOT spinning a five!

20% + 18% + 22% + 21% = 81%

Therefore, the probability of not spinning a five is 81%.

(While writing all of this down, I realized it was completely unnecessary)

Basically, the total probability of all of these numbers is equal to 100%.  The probability of spinning a five is 19% as we inquired above.  Therefore, all we need to do is subtract 19% from 100%!

100% - 19% = 81%

According to the graph, there is a 81% chance of not rolling the 5. If it is 19% 5’s then 100 - 19 = 81.

(PLS HELP MY TEACHER WANTS ME TO PASS THIS!) Which line on the graph is the image of the line y = 2x after a transition of 3 units along the x-axis and 4 units along the y-axis?

Answers

The answer is line a

Line y=2x ==> No matter what value Y gets, X is always half of it

But X was transitioned by 3 units and Y by 4, so let's pull them back down

==> y-4 = 2x-3

Upon verifying each of the lines with y = 6:

A. 6-4 = -4-3 ==> 2 = -7. A falls

B. 6-4 = 4-3 ==> 2 = 1. B falls, but this one's the closest to truth

C. 6-4 = 8-3 ==> 2 = 5. C and D will obviously fail because X is so far ahead.

Out of testing, B is the only correct answer, despite the answers being close instead of true

Good luck! Hope this helps!

Answer:

the answer for this question should be 6 because remember we need to substitue n by -3 so first we need to solve the exponent one so we replace it.

-3^2= 9

-3 times -3= 9 and remember this rule when we multiply an negative times a negative is positive so it would be 9 for n^2 so we need to add 9+-3 and we get an answer of 6 so 6 is the correct answer and remember if the base is an negative and the exponent is even the answer is positive but if it is odd it would be negative.

hopefully 6 is the correct and have a great day.
