Find (8.4×108) ÷ (1.2×103). Express your answer in scientific notation.

Answers

Answer 1

Answer: 7.33980582 x 10^0

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.

Answer 2

The expression in scientific notation is 7 ×10^5

What is the basic arithmetic operations?

The four basic mathematical operations are Addition, subtraction, multiplication, and division.

Given that the terms are;

(8.4×10^8) ÷ (1.2×10^3)

Step 1: Divide the numerical parts:

8.4 ÷ 1.2 = 7

Step 2: Subtract the exponents:

10^8 /10^3 = 10^5

Now Putting the numerical part and the exponent together, we get:

7 ×10^5

Hence, the result of the expression in scientific notation is; 7 ×10^5

120°

Answers

Answer:

115 degrees

Step-by-step explanation:

We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.

Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees

Answer:

choice 3) W = 115 degrees

Step-by-step explanation:

all triangle interior angles add up to 180 degrees

180 = 45 + 70 + X

X = 65 degrees

Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)

W = 180 - 65 = 115 degrees

Why is it a problem to find the square root of a negative number, for example √-4?

Answers

Answer:

It is not possible because no number times itself can equal a negative number.

Answer:

Taking the square root of a negative number is a problem because this technically does not follow the rules of a square root. A square root is made of a number times itself, and therefore, is impossible to have a negative times a positive to make a negative total (An example would be √4, as the answer can be 2 (because 2 x 2 = 4) or -2 (because -2 x -2 = 4)).

This means that in order to solve √-4, you must use imaginary numbers. This is represented by "i."

For the example of √-4, your answer would be 2i. These imaginary numbers are used whenever you are square rooting a negative number in order to show that it is breaking the real rules of roots.

There are some flowers in a shop.

Each flower is either red or yellow.

Each flower is either a tulip or a rose.

For these flowers

number of tulips : number of roses = 6:5

number of red tulips : number of yellow tulips = 3:4

Work out the proportion of the flowers that are red tulips.

Nyour answer

Answers

Answer:

Proportion of the flowers that are red tulips = [tex]\frac{2.57}{11}[/tex]

Step-by-step explanation:

Given - There are some flowers in a shop.  Each flower is either red or

             yellow.  Each flower is either a tulip or a rose.  For these flowers

              number of tulips : number of roses = 6:5  and number of red tulips :    

             number of yellow tulips = 3:4

To find - Work out the proportion of the flowers that are red tulips.

Proof -

Let Total number of flowers in a shop = 11x

As given, number of tulips : number of roses = 6:5

⇒Total number of tulips in a shop = [tex]\frac{6}{11}.11x[/tex] = 6x

   Total number of roses in a shop = [tex]\frac{5}{11}.11x[/tex] = 5x

Now,

As given, number of red tulips : number of yellow tulips = 3:4

⇒Total number of red tulips = [tex]\frac{3}{7}.6x[/tex] = 2.57x

   Total number of yellow tulips = [tex]\frac{4}{7}.6x[/tex] = 3.43x

∴ we get

Proportion of the flowers that are red tulips = [tex]\frac{2.57x}{11x}[/tex] = [tex]\frac{2.57}{11}[/tex]

Solve the simultaneous equations
2y - 5x = 9
4y + 3x = 5
Do not use trial and improvement

Answers

Answer:

y = 2, x = -1

Step-by-step explanation:

2y - 5x = 9

2y = 9+5x

y = (9+5x) /2

4y + 3x = 5

4((9+5x) /2) + 3x = 5

13x + 18 = 5

13x = -13

x = -1

y = (9+5x) /2

y = (9+5(-1)) /2

y = 2

Answer:

x = -1, y = 2

Step-by-step explanation:

2y - 5x = 9

4y + 3x = 5

eliminate one of the variables by multiplying the equations and then adding them together.

3(2y - 5x = 9)

5(4y + 3x = 5)

6y - 15x = 27

20y + 15x = 25

26y = 52

y = 2

now input the value of y into one of the original equations to find x.

8 + 3x = 5

8-5 = 3

x = -1

15 lb ≈ ? kg

Answers

Answer:

6.82 kg

Step-by-step explanation:

set up a proportion based on 2.2 lbs in 1 kg

2.2/1 = 15/x

cross-multiply:

2.2x = 15

x = 6.82

The value of 15 lb in kg is 6.81 kg.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We know that;

⇒ 1 lb = 0.454 kg

Hence, We get;

⇒ 1 lb = 0.454 kg

⇒ 15 lb = 15 × 0.454 kg

            = 6.81 kg

Thus, We get;

⇒ 15 lb = 6.81 kg

there 6 more girls than boys in a class there 44 students in the class in all how many boys are there

Answers

Answer:  28 boys and 16 girls

Step-by-step explanation: Divide 44 by 2 to get 22 subtract 22 by 6 to get the girls and add 6 to 22 to get the boys.

Answer:

44% of the students of a class are girls. If the number of girls is 6 less than the number of boys, how many students are there in the class?

let x be the number of boys, so (x - 6) will be number of girls.

total number of students will be boys plus girls : x + (x - 6) = 2x - 6

now 44% are girls which come from formula no. of girls divide by total students into 100: (x - 6)/(2x-6)*100 = 44

by solving we get x = 28 (where x is number of boys)

now x - 6 = 28–6 = 22 (number of girls)

add both we get total number of students = 28 + 22 = 50
