a.) 20
b.) 22
c.) 24
d.) 26

Answers

Answer 1

Answer:

The answer is B.)22

Step-by-step explanation:

3∗5+5∗3

⇒3∗5=2×3−3×5+3×5

=6−15+15

=6

⇒5∗3=2×5−3×3+3×5

=10−9+15

=16

Therefore,3∗5+5∗3

⇒6+16=22

Thus the ans is 22

Aaron went shopping for a new camera because of a sale. The store was offering a 10% discount. If the price on the tag was $27, what would be the price after the discount but before tax, to the nearest dollar and cent?

Answers

Answer:

$24.30

Step-by-step explanation:

You can do this two ways! One way to do this is to transform the 10% into decimal form. So, move the decimal over to the left 2 places and you get from 10% to .10

Multiply .10 by 27 to get how much money to take off.

.10 x 27 = 2.70

Now, subtract 2.70 (which is your discount) from 27 and you get:

27 - 2.70 = 24.30

The second way you can do this is to multiply what you DO have to pay by 27. Since we're NOT going to pay the 10% since it's a discount, we'll be paying the other 90%. (100% - 10% = 90%) Let's do the same and turn 90% into a decimal, which is .90

Multiply .90 by 27 to get how much money you have to pay.

.90 x 27 = 24.30

Answer:

36π

Step-by-step explanation:

diameter = 6 so radius is 3
[tex]\frac{4}{3}\pi r^{3}[/tex]
r = 3
[tex]\frac{4}{3}\pi *27[/tex]
= 36π

v = 4/3 pi r ^2 (radius squared)

the radius is half of the line you were given so its 3 (6/2=3)

Answers

Answer:

Task 1:

Change the second equation into:

x=3y-12

Then substitute 3y-12 for x in the first equation:

2(3y-12)-6y=5

6y-24-6y=5

-24≠5

no solution

Task 2

We know that the two lines in the system of equations have the same slope. The solution in task 1 means that the two lines have to be parallel, as they do not intersect.

2x - 6y = 5    x - 3y = -12

-2x____-2x___ x - 3(1/3x - 5/6) = -12

Yolanda was pouring glasses of juice for brunch. She used a 48-ounce bottle of apple juice to fill 8 glasses equally, and she used a 35-ounce bottle of orange juice to fill 7 glasses equally. Which contained more juice, a glass of apple juice or orange juice? Explain.

Answers

Answer:

apple juice

Step-by-step explanation:

Divide the bottle of apple juice by the number of glasses to get the amount of juice 1 glass holds:

48 / 8 = 6

Therefore, each glass holds 6 oz of apple juice

Divide the bottle of orange juice by the number of glasses to get the amount of juice 1 glass holds:

35 / 7 = 5

Therefore, each glass holds 5 oz of orange juice

A glass of apple juice contained more juice as 6 > 5

Answer: Apple Juice.

Step-by-step explanation:

You have to divide the bottles of apple juice by the number of glasses to get the amount of juice one glass carries. ( 48/8) which is 6. Then when you divide the bottles of orange juice by the number of glasses to get the the amount of juice a glass carries. (37/7) which is 5.

i don't under stand how to solve this pleas help this is the question -9x -13 =103

Answers

Answer:

[tex]x = -12\frac{8}{9}[/tex] or -116/9

Step-by-step explanation:

Use algebraic manipulation:

Note: Remember, anything you do to one side of the equation you also do to the other side (e.g. +5 on one side, +5 on the other side).

First, multiply the whole equation by -1 to get the x to be positive so you get:

9x + 13 = -103

then subtract 13 from both sides:

9x = -103 - 13

9x = -116

then divide by 9:

x = -116/9

[tex]x = -12\frac{8}{9}[/tex]

Answer is -111/9 or -12.888889

The scatter plot shows the systolic blood pressure of people of several different ages. The equation represents the linear model for this data.



y = x + 95



According to the model, how much does the systolic blood pressure increase for each year of age?


1 mm Hg per year

5 mm Hg per year

15 mm Hg per year

95 mm Hg per year

110 mm Hg per year


A graph measuring systolic blood pressure in relation to age. A line indicates that blood pressure increases as age increases

Answers

Looking at the equation y= x + 95
We can see it is in the format y = mx + b,
where m represents the slope, or the rate of increase.

Since x is alone, it is assumed to be “1x”, with 1 being m, the slope.

Therefore the systolic blood pressure increases by 1 mm Hg per year.

Another way to solve this if you didn’t have the equation:

If we find two easy to pinpoint plots such as:
(0,95) (15,110)

The equation for slope is

x - x / y - y

15-0 / 110-95

= 15/15
= 1

(6 2/5 + 8 6/10) + 7 2/10

Step-by-step explanation:

Brainliest????? :))

(lol jk)

(if you want)

Prediction for the passwords with the probability of first character is consonant is equals to 467passwords (nearest whole number).

What is probability?

" Probability is defined as the mathematical expression which represents the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]

According to the question,

Total numbers used make passwords  from 0 to 9 = 10

Total lower case letters a to z =26

Number of consonant =21 letters

Total characters = 26 + 10

                           = 36

Substitute the value in the formula we get,

Probability first letter to consonant = 21/ 36

Therefore,

Prediction for the number of passwords out of 800 passwords first character is a consonant  

= 800 × ( 21/ 36)

= 466.666..

= 467 passwords( nearest whole number)

Hence, prediction for the passwords with the probability of first character is consonant is equals to 467passwords (nearest whole number).

a loss of $500 dollars in the stock market is worse than a gain of $200 in the stock market. Write an inequality that relates the rational numbers

Answers

Answer:

-500 < 200

Step-by-step explanation:

In inequality,

less than = <

greater than = >

Less than equal to = ≤

Greater than equal to = ≥,

Here, the given sentence is, loss of $500 is worse than a gain of $200

Generally, loss represents by an amount with a negative sign, That is, loss of $ 500 = - $ 500 Also, worse than is equivalent to less than. Thus, the required inequality would be, -500 less than 200 ⇒ -500 < 200
