Answer:

Shenika invites 7 friends and each one gets 5 cookies.

= 7*5

= 35

Based on above answer, Shenika will need a total of 35 cookies for all.

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

Each box has 12 cookies.

Total cookies = 35

Let the number of boxes be x.

12*x = 35

x = 35/12

x = 2.9

This means she would need 3 boxes.

Answer:

9

Step-by-step explanation:

sum of the terms

mean=------------------------------

number of the terms

The mean of the numbers is 9.

Mean is a measure of central tendency. It is the average of a set of numbers. The value of the mean of a set of numbers can be determined by adding the given numbers together and dividing it by the total number.

Mean = sum of numbers / total numbers

Sum of numbers = 7 + 21 + 2 + 17 + 3 + 13 + 7 + 4 + 9 + 7 + 9 = 99

Total number = 11

Mean = 99 / 11 = 9

x[tex]x=\sqrt{19^2-10^2}=\sqrt{361-100} =\sqrt{261} \approx16.15549\\\approx16.16[/tex]

Step-by-step explanation:

x=\sqrt{19^2-10^2}=\sqrt{361-100}  =\sqrt{261} \approx16.15549\\\approx16.16

The requried measure of length x in the right triangle is 16.15 units.

In a right-angled triangle, its sides, such as hypotenuse, and perpendicular, and the base is Pythagorean triplets.

Here,
For the given right-angle triangle,
Applying the Pythagoras theorem,
hypotenuse² = perpendicular² + base²
19² = 18² + x²
x = √19² - 10²
x = 16.15

Thus, the requried measure of length x in the right triangle is 16.15 units.

Answer:

Step-by-step explanation:

Each movie is $12.00. 10% off of 12% is 12-1.2 = 10.8

The final amount spent is 5%, that means we can multiply the end amount spend by 1.05

The maximum Stan can spend is $95

[tex](10.8m)*1.05\leq 95\\(10.8m)\leq 90.4762\\m \leq \frac{90.4762}{10.8}\\m\leq 8.3774[/tex]

Now, you can't buy 0.3 of a movie, so the most Stan can buy is 8 movies

Step-by-step explanation:

John can mow the same lawn in 3 hours.

In 1 hour he can mow 1/3rd of the lawn.

In 1 hour they can together mow (1/2+1/3)=5/6th of the lawn.

Together they can mow the lawn in 6/5 hours=1.2 hours.

I hope this helped, please mark Brainliest, thank you!!

Time taken to mow the lawn together is 6/5 hours i.e., 1.2 hours.

The correct option is (C).

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

Given:

John can mow his lawn in 3 hours.

Julie can mow same lawn in 2 hours.

In 1 hour = 1/3rd of the lawn.

In 1 hour, together they can mow

= (1/2+1/3)

=5/6th of the lawn.

Hence, time taken to mow the lawn together is 6/5 hours i.e., 1.2 hours.

Answer:

y-y1 = m(x-x1)

y - 2 = 3(x-1)

y=3x-3+2

y=3x-1

Step-by-step explanation:

first you type down point slope formula

then you plug in the information you have point (1,2) 1 is x1 and 2 is y1 m is 3 because m = slope

then you have to distribute the 3 to the x and the -1 and then isolate y

(how to isolate the y) you must do the opposite of -2 which is +2 whatever you do on one side you have to do to the other

then you combine like terms 3x is alone and -3 +2 equals -1

Answer:

62

Step-by-step explanation:

Let the two digit number be XY

X+Y = 8

10X+Y - (10Y+X) = 10Y+X+10

10X+Y-10Y-X=10Y+X+10

8X-19Y=10

8(8-Y)-19Y=10

64-8Y-19Y=10

27Y=54

Y=2

The number is therefore 62.

The required two-digit number with sum of digits as 8 is 62.

Let us say the number is xy

The place value of digits, x and y in the number xy are 10 and 1 respectively.

So the number xy can be written as 10x+y

When the digits are reversed

The new number or reversed number obtained will be yx

So the new number yx can be written as 10y+x

Since the difference between the original number and the reversed number is 10 more than the reversed number.

So, (10x+y) - (10y+x) = 10 + (10y+x)

8x-19y =10.......(1)

Since the sum of digits is 8

So, x+y = 8......(2)

By solving equations (1) and (2) we get

x=6, y=2

So, the required number is xy i.e. 62.

Therefore, The required two-digit number with sum of digits as 8 is 62.
