Answer 1

Answer:

Option A and E

Step-by-step explanation:

Because

2×3²×5 =90

And

2×3×3×5 =90

Answer 2

Answer:

A; 2 * 3^2 * 5

Step-by-step explanation:

Factorization is when you multiply numbers to the lowest form

so to get 90 you can do

45 * 2 = 90

9 * 5 = 45

3 * 3 = 9

2 * 3 * 3 * 5 = 90

What is the prime factorization of 18?

Answers

Answer:

2 x 3 x 3

Step-by-step explanation:

Prime Factorization is finding which prime numbers multiply together to make the original number.

Prime numbers are whole numbers greater than 1 that cannot be made by multiplying other whole numbers: 2, 3, 5, 7, 11, 13, 17, 19 ... etc.

Factors are the numbers you multiply together to get another number.

To find the prime factors of 18:

Start with dividing the number by the first prime number, 2.

So can 18 be divided by 2? Yes: 18 ÷ 2 = 9 ⇒ So 2 is a factor.

However, 9 is not prime number. Can 9 be divided by 2 and give us a whole number? No, as 9 ÷ 2 = 4.5 and 4.5 is not a whole number.

So let's try dividing 9 by the next prime number, 3: 9 ÷ 3 = 3.

We can now stop as we divided by the prime number 3 AND the result is a prime number.

Therefore, the prime factorization of 18 = 2 x 3 x 3

As two of the factors are the same (3) , we can also write this using exponents: 18 = 2 x 3²

Refer to the picture framing problem. A new picture with the dimensions 25 in by 10 in will be framed with fancy that is 15 in by 10 in. What will be the dimensions of frame that will surround the picture? Show all work in finding the solution.

Answers

The difference between values is gotten by subtracting the values

The dimension of the frame that will surround the picture is 10 inches by 0 inches

How to determine the dimension of the picture

The given parameters are:

Picture = 25 inches by 10 inchesFancy = 15 inches by 10 inches

The dimension of the frame is the difference between the dimension of the fancy, and the picture.

So, we have:

Length = 25 inches - 15 inches

Length = 10 inches

Width = 10 inches - 10 inches

Width = 0 inches

Hence, the dimension of the frame that will surround the picture is 10 inches by 0 inches

Answer:

x = -24

Step-by-step explanation:

First, distribute 2 to all terms within the parenthesis:

2(x + 11) =

2 * x = 2x

2 * 11 = 22

2x + 22 = -26

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

First, subtract 22 from both sides of the equation:

2x + 22 (-22) = -26 (-22)

2x = -26 - 22

2x = -48

Next, divide 2 from both sides of the equation:

(2x)/2 = (-48)/2

x = -48/2

x = -24

x = -24 is your answer.

A ball is dropped from a height of 500 m the table shows the height of each bounce write a rule to represent the height of the ball after each bounce how high does the ball bounce of the 6th bounce

Answers

The rule that represents the height of the ball after each bounce is;

H(n) = 400(0.8)^(n - 1)

Geometric Sequence Progression

From online sources, we have that;

After first bounce, height = 400 m

After 2nd bounce, height = 320 m

After 3rd bounce, height = 256 m

Formula for the nth term of a geometric sequence is;

T_n = ar^(n - 1)

First term is 400m

Since second term is 320, then common ratio is;

r = 320/400

r = 0.8

Thus, the 6th bounce which is the 6th term will be;

T_6 = 400 * 0.8^(6 - 1)

T_6 = 131 m

Suzie Chambers sells cars for a living. She earns $450 per week plus a commission of 5% on
sales. One week she sold $9600 worth of cars. How much in total did she earn for that week?

Answers

Answer:

umm so if she makes $50 a week she must have sold special cars, possibly like super cars i guess?

Step-by-step explanation:

The total money Suzie earned in that week is $930.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Suzie Chambers sells cars for a living. She earns $450 per week plus a commission of 5% on sales.

One week she sold $9600 worth of cars.

Now, the total money earned

= 450+5% of 9600

= 450+5/100 ×9600

= 450+0.05×9600

= 450+480

= $930

Therefore, the total money Suzie earned in that week is $930.
