Answer: It means that there are 570 chocolate chips in all the 30 cookies

Step-by-step explanation:

The mean also referred to as the average of a data set is calculated by adding all numbers in a data set and dividing by number of values in the set.

Since the mean number of chocolate chips in 30 cookies is 19 chocolate chips, this means that there are:

= (30 × 19) = 570 chocolate chips in the cookies.

Answer:

Step-by-step explanation:

(x +13) + (4x + 2 ) = 180

5x + 15 = 180

Subtract 15 from both sides

5x = 180 - 15

5x = 165

Divide both sides by 5

x = 165/5

x = 33

Check

x + 13 = 33 +13  = 46

And

4x + 2 = 4*33 + 2 = 132 + 2 = 134

Answer:

8.106

Step-by-step explanation:

Use Pythagorean Theorum for this question, a^2+b^2=c^2

If you put the numbers into the equation you get 6.3^2+5.1^2=c^2.

Simplify and get 65.7=c^2

To get rid of the square, you square root both sides, which will get you 8.106=c (since the answer wants round to 3 numbers behind the decimal point)

Therefore the missing length is 8.106cm. (For estimation just write a random number you think it would be before actually solving the problem.

Step-by-step explanation:

Just use the pythagorean thereum for each of the questions to see if the values match up

Answer:

a) y=(300-150)x-2100

b) y=150x-2100

c) y=150(140)-2100

y=18900

Jose was wrong. He did not make 20000 dollars last year.

Answer:

A: ((300-150) * 140) - 2100

B: 21000-2100= $18,900 profit.

Jose made 18,900 dollars worth of profit. He did not make $20,000 worth of profit.

Answer: 12.6 years

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:  

A = P (1 + r/n) nt  

Where:  

A = Future value of investment (principal + interest)  

P = Principal Amount  

r = Nominal Interest Rate (decimal form, 4/100= 0.04)

n= number of compounding periods in each year (1)

t = years

Replacing with the values given  

8200= 5000(1+ 0.04/1)^1(t)

Solving for t

8200 =5000 (1.04)^t

8200/5000 =(1.04)^t

1.64 =(1.04)^t

log 1.64 =log (1.04)^t

log 1.64 = t log (1.04)

log 1.64/ log (1.04) =t

t = 12.6 years

Answer:

k=29

Step-by-step explanation:

(5K-3)+(9+k)=180

6k+6=180  add like numbers

6x=174        subtract 6 from 180

x=29           divide by 6

The solution is : k=29, is the value of k.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

Here, we have,

from the given diagram, we get,

(5K-3)+(9+k)=180

6k+6=180     [add like numbers]

6x=174       [ subtract 6 from 180]

x=29          [ divide by 6]

Hence, The solution is : k=29, is the value of k.

Answer:

19b-4

Step-by-step explanation:

7b+3(4b-2)+6÷3

Bracket comes first so we distribute 3 over the terms in the bracket

= 7b + 12b -6 +6 ÷ 3

First we solve division

= 7b + 12b -6 +6 ÷ 3

= 7b + 12b -6 +2

= (7b+12b)+(-6+2)

= 19b -4

This can't be simplified further as it can't be solved anymore

Answer:

19b - 4

Step-by-step explanation:

Distribute the 3 to (4b - 2), like so:

3(4b - 2)

12b - 6

→ 7b + 12b - 6 +6 ÷ 3

Add like terms:

→19b - 6 + 6 ÷ 3

Following PEMDAS, you divide 6 by 3 first:

→19b - 6 + 2

Add like terms:

→19b - 4

Steps:

Step 1: Simplify both sides of the equation.

4x+3=9

Step 2: Subtract 3 from both sides.

4x+3−3=9−3

4x=6

Step 3: Divide both sides by 4.

4x /4  =  6 /4

Answer:

B

Step-by-step explanation:

From the graph you see point (1, -2) is on f(x)

So substitute x = 1 and the resuult should be -2.

The only function that is valid, is function B.

Answer:

3) The function's leading coefficient is negative.

Explanation:

(1) Is not the answer because when x = 3, f(x) = 0.

(2) Is not the answer because when f(x) = -3,

x = 0.

(4) Is also not the answer because the y-values on both sides of (1, -4) are mirroring each other.

Therefore,

(3) is the answer, by elimination, but also because there is not proof of the leading coefficient being negative, as we don't see the original equation.

Answer: 36

The LCM of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 is 2 × 3 × 2 × 5 × 7 × 2 × 3 × 11 = 27720.

A multiple of 27720 will end in 0, and the sum of its digits will be a multiple of 9.

The largest 6-digit number which is multiple of 9 with last digit of 0 is 999990, and the sum of its digits is 45. 45 is not a multiple of 27720, and there is no other way to get a digit sum of 45.

We now look at the next biggest multiple of 9, 9 × 4

= 36.

The largest 6-digit multiple of 27720 is 27720 × 36 = 997920, and the sum of its digits is 36.

Answer:

x = 18

Step-by-step explanation:

Given

[tex]\frac{3x}{5}[/tex] + 1 = [tex]\frac{4x}{15}[/tex] + 7 ( subtract 1 from both sides )

[tex]\frac{3x}{5}[/tex] = [tex]\frac{4x}{15}[/tex] + 6

Multiply through by 15 to clear the fractions

9x = 4x + 90 ( subtract 4x from both sides )

5x = 90 ( divide both sides by 5 )

x = 18

Answer:

50 songs at $35

Step-by-step explanation:

Answer:

x = 50, y = 35

Step-by-step explanation:

Solve this system of linear equations by using substitution.  Equate the two equations to one another, thus eliminating y:

0.4x + 15 = 0.2x + 25

subtract 0.2x from both sides, obtaining:  0.2x + 15 = 25, or, after combining the constants, 0.2x = 10.

Finally we divide both sides by 0.2, which results in x = 50.

Use the first equation to find y:  y = 0.4(50) + 15 = 20 + 15 = 35

Answer:

H≤7

Step-by-step explanation:

Answer:

Given below

Step-by-step explanation:

M is Mikey and B is Betty in,

Current ages:

M= x

B= 3x (cuz she is 3 times older)

After 5 years

M= x+5

B= 3x+5 (5 years added to present age)

It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))

So,

3x+5 = 2(x+5)

3x+5 = 2x+10

3x -2x = 10-5

x = 5

Therefore,

The current ages are

Betty : 3x = 3*5 = 15

Mikey: 5 (x)

You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)

Answer: The current ages are

Betty : 3x = 3*5 = 15
