Find the exact sum or difference.

7/15+9/10

A. 7/9

B. 1 13/15

C. 2 2/9

D. 1 1/15

Answers

Answer 1
Ok so to solve this question you need to find the least common denominator of both fractions which is 30. To get 15 to 30 you have to multiply it by 2. So multiply both sides of the fraction by 2 and you get 14/30 + 9/10
Do the same thing with 9/10 but multiply it by 3
That gives you 14/30 + 27/30 which = 41/30 which is 1 and 11/30
So none of these answers are correct
Answer 2
if you add it’s 1 11/30 and if you subtract it is -13/30 . so therefore they had a typo in the answers or you asked the question wrong sorry. have a great day ! :)

What is the measure of an interior angle of a regular decagon?

144°

180°

36°

Answers

Answer: 180

Step-by-step explanation:

Answer:

Step-by-step explanation:

A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.

Given the equation 6x + 18 = 72:

Part A: Write a short word problem about a purchase made to illustrate the equation. (6 points)

Part B: Solve the equation showing all work. (4 points)

Answers

Answer:

Part A: You are buying candy bars online. They cost $6 each and there is an $18 shipping fee. You have $72 to spend. How many candy bars can you get?

Part B: x=9

Step-by-step explanation:

6x + 18= 72

You want to get x alone:

Subtract 18 from both sides

Rewrite:

6x= 72-18

Now, subtract 72-18

Rewrite:

6x= 54

Divide 6 from both sides

So, that would be 54/6

Step-by-step explanation:

You would simply multiply $0.09 and 12.  Decimals are frequently multiplied by treating them as whole numbers before placing the decimal point in the result. Where the decimal point is placed in the solution depends on how many digits are present in the factors following the decimal points. For instance, 0.3 x 0.8 equals 0.24.

PLEASE HELP ASAP THIS IS DUE IN 1 HOUR I GIVE BRAINLIEST, FIVE-STAR RATING, A HEART, AND 50 POINTS TO ANYONE WHO CAN HELP ME WITHIN THE NEXT 45 MINUTES!!!

Answers

Answer:

First, simplify the parentheses. Then, do exponents. Next, multiply. Finally, add and subtract from left to right.

Step-by-step explanation:

Answer:  You always complete multiplication and division before addition and subtraction, working left to right inside the parentheses first.

For example, if your equation was:

23 + (12 x 5 + 6 -7), then you would first complete the multiplication (12 x 5), then add 6 (+6), then subtract 7 (-7), and lastly add 23 (+23) which is outside the parentheses.

Your example:

40 ➗ 1 + 3 - (3 x 7) + (7 - 5)

First: (3 x 7)

second: (7 - 5)

third 40 / 1

fourth: 40 + 3

fifth: 43 - 21

sixth: 22 + 2

=24

Step-by-step explanation:

You should always follow the order of operations rule that follows a sequence of evaluation steps for a given expression. Remember the order using PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right). Therefore, you first complete work in the parentheses for multiplication & division (working left to right) and then addition and subtraction (working left to right). Then you complete any math (following the same order) outside the parentheses.

A large box of cereal has 26 ounces and costs $5.20. What is the unit rate price per ounce for the large box of cereal?

Answers

Answer:

$0.20

Step-by-step explanation:

Hey! Let's help you with your question here!

So, let's start with what we are trying to find and that's the unit rate price per ounce of a large box of cereal. Now, let's focus on what we're given.

Information we know:The large box of cereal is 26 ounces.The cost of the box of cereal is $5.20

Explanation:

Alright! We've figured out what we know and what we need to find! Now, we can start figuring out how to solve it! Now how do we do that? Well in order to figure out the unit rate price, we need to take the price and divide it by the total quantity. In a formula, it looks like this:

[tex]Unit Rate=\frac{cost}{quantity}[/tex]

If we plug everything into the formula, it would look like this:

[tex]UnitRate=\frac{5.20}{26}[/tex]

[tex]UnitRate=0.20[/tex]

Conclusion:

Therefore, we can conclude that the unit rate price per ounce for the large box of cereal is $0.20 per ounce.

um what does this mean. Which number has factors besides 1 and itself?

Answers

Answer:

A composite number is a number that has at least one factor besides 1 and itself, or any number which is not prime (although the number 1 is neither prime nor composite). For example, 91 is a composite number. To determine whether a number is composite, determine whether or not it is prime.

Step-by-step explanation:

I don't know if this is the right answer or thread equation but here

"Which number has factors besides 1 and itself?"

Answer: Composite Number

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.[3][4]

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.

The composite numbers up to 150 are:

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134, 135, 136, 138, 140, 141, 142, 143, 144, 145, 146, 147, 148, 150.

a equals negative 37 over 24

Step-by-step explanation:

-a-(7/8)=2/3

Add 7/8 to 2/3.

Multiply the numerator and denominator of each fraction by the other's denominator. This keeps the same value for each fraction but makes them easier to add because they have the same denominator.

(7*3)/(8*3)+(2*8)/(3*8)

(21/24)+(16/24)

Add the fractions (add the numerators and keep the denominator).

(21/24)+(16/24)=37/24 or 1 13/24

-a=37/24

Divide 37/24 by -1.

Answers

Answer:13

Step-by-step explanation:

Calculate the quotient in the brackets (if you follow PEMDAS/BEDMAS, brackets come first.)

-4/12 = -0.33

-2/15 = -0.133

This gives you (-0.33)(-0.133)

Next, multiply both brackets together.

(-0.33)(-0.133) = appx. 0.044

Now that you have the product of the two brackets, calculate 5/6

5/6 = 0.833

Finally, sum it all up. Since the last two numbers are negative, we subtract them.

0.833 - 0.33 - 0.133 =

Therefore, the answer is 0.37

Answer:

Step-by-step explanation:

you don't have the option to what the drop downs say so I'm giving my best guess as to what they all say based on context.

-----------------------------------------------------------------------------------

Data Set B has distant outliers, so it has a lower MAD.

The smaller MAD of Data Set A suggests that most of the data is less than the mean that is in Data Set B

However, most of the data in Data Set A is (unknown) spread out from the mean than in Data Set B

Therefore, MAD is not reliable when there is an outlier.

Since we have 19x on both sides, whatever else we do is moot because you can't take 19x from 19x without completing getting rid of the variable.

S:{−5}
S:{3}
S:{12}
S:{42}
I WILL GIVE BRAINIEST FOR THIS ONE!!

Answers

Answer:

The integer that makes the inequality false is D, 42

Step-by-step explanation:

Start the problem by expanding the inequality.

[tex]3\left(n-6\right) = 3n-3\times 6\\=3n-18\\----------\\2\left(n+12\right) = 2n+2\times 12\\=2n+24\\----------\\= 3n-18 < 2n+24[/tex]

Add 18 to both sides. When doing inequalities, always add the singular number or coefficient on the left side. Afterwards, simplify.

[tex]=3n-18+18 < 2n+24+18\\=3n\left(-18+18\right)\\=-18 + 18\\=3n-\left(0\right) < 2n+24+18\\=2n\left(24 + 18\right)\\=24 + 18\\=42\\=3n-\left(0\right) < 2n+42\\=3n < 2n+42[/tex]

Subtract by 2n, the coefficient on the right side.

[tex]3n-2n < 2n+42-2n\\=3n-2n < \left(2n+(42)-2n\right)\\= \left(2n+(-2n)\right)\\=3n-2n < 0+42-0\\3n-2n = 3-2\\= 1\\= "n"\\= 1n\\= 1\times n\\= 1\:or\:"n"\\= n < 42[/tex]

Given that n is less than 42, we can conclude that 42 would make the inequality false.

Hope this helps!
