What is 71,000,000 converted to scientific notation?
A. 71 x 100,000
B. 7.1 x 100,000
C. 7.1 x 10-7
D. 7.1 x 107

Answers

Answer 1

Answer:

7.1 × 10 7

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 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer 2

Answer:  D)  [tex]7.1 \times 10^7[/tex]

Explanation:

Place the decimal point between the first two digits of the given number. Erase everything after the '1'. So we have 7.1

To get back to 71,000,000 we would need to move the decimal point 7 spaces to the right

So that's why [tex]7.1 \times 10^7 = 71,000,000[/tex]

If the exponent was -7, then we would move the decimal point 7 spaces to the left.

Penguins can swim at a speed of up to 33 ft./s use dimensional analysis to convert the speed to miles per hour 1 mile equals 5280 feet

Answers

Answer:

v = 22.5 miles/hour

Step-by-step explanation:

It is given that,

The speed of Penguins is 33 ft/s.

We need to convert the speed to miles per hour.

We know that, 1 mile = 5280 feet

Speed,

[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]

So, the speed of the Penguins is 22.5 miles/hour.

express the ratio 60cm to 20m
​

Answers

Answer:

3 cm : 1 cm

Step-by-step explanation:

1. 60 : 20

2. divide 10 on both sides = 6 : 2

3. divide by 2 on both sides = 3 : 1

4. 3 cm : 1 cm

I'm so sorry, I just read the ratio is 60 cm to 20 M

So edit:

convert both into a unit, we'll take m.

1 cm = 100 m

so 60 x 100 = 60000 m

= 60000 m : 20 m

= divide by 20 in both sides...

= 3000 m : 1 m

What is a system of equations?

A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.

Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.

If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.

Therefore, the given equation is linear with two variables that will have zero solutions.

Question 3
Mathematics

Answers

The answer is C) -2x+10

When doing the distributive property, multiply -2 and x to get -2x. Then, multiply -2 and -5(remember when you multiply a negative with a negative, you get a positive number) to get 10. Therefore your answer would be -2x+10.

Hope this helps!

The equivalent expression is: -2x + 10. therefore the correct option is C.

What are equivalent expressions?

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

From the distributive property;

-2(x - 5)

Then, multiply -2 and -5

-2 * x = -2x

-2 * -5 = 10

because two negatives make a positive

Therefore the answer would be -2x+10.

Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.
