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?
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

If she did not make any free throws, how many 2 point and how many 3 point shots did she make in these two games? Give me the variables and write the two equations I will solve the rest - Thank you
Answer:2
Step-by-step explanation:
help me please - look at pic
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
-6y = -2x +5____ x - 1x + 5/2 = -12
----__-----__---______5/2 = -12
-6___-6_-6________-----___----
__________________ 5/2___ 5/2

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.
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
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]

A computer is used to generate passwords made up of numbers 0 through 9 and lowercase letters. The computer generates 800 passwords one character at a time.
A uniform probability model is used to predict the first character in the password.
What is the prediction for the number of passwords in which the first character is a consonant?
Round your answer to the nearest whole number.
111 passwords
222 passwords
467 passwords
646 passwords
Answer:
c
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).

Answer:
-2 3/8, -2.325, -17/-8
Step-by-step explanation:
- 2 3/8 = -2.375
-17/-8 = 17/8 meaning that it is POSITIVE and that it is the GREATEST
Compare -2.375 and -2.325
2.375 is larger than 2.325
However, since this is negative, -2.375 is smaller.
Therefore, the order is -2 3/8, -2.325, -17/-8.

B (400 ÷ 5) - (600 ÷ 5)
C (4000 ÷ 5) - (60 - 5)
D (4000 ÷ 5) + (600 ÷ 5)
The expression that can be used to solve the given equation 4600 ÷ 5 is; D: (4000 ÷ 5) + (600 ÷ 5)
How to carry out mathematical operations?We are given the equation; 4600 ÷ 5
Now, the individual numbers can be further simplified to get;
4600 = 4000 + 600
Thus, we have;
(4000 + 600) ÷ 5
Thus, by distributive property, we have;

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
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
