which is largest 3.3 times 10^5 or 3.1 times 10^5

Answers

Answer: 3.3 times 10^5 is bigger

Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.

so 100,000 multiplied by 3.3 = 330,000

or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.

3.3 x 10^5 = 50.3 and 3.1 x 10^5 = 50.1

Jada is making a scale model of the solar system. The distance from Earth to the moon
is about 2.389 × 105 miles. The distance from Earth to the sun is about 9.296x 107
miles. She decides to put Earth on one corner of her dresser and the moon on another
corner, about a foot away. Where should she put the sun?

Answers

Answer:

she should put the sun 2.8 miles away

Step-by-step explanation:

had this question and got it right.

She should place the sun 389.1167 feet away The distance from Earth to moon (2.389*10^5 miles) was represented by a foot of distance.
If we apply a rule of three
1 foot ----------------------- 2.389*10^5 miles
x --------------------------9.296*10^7 miles
x = ( 9.296*10^7 miles * 1 foot) / 2.389*10^5 miles

Answers

Answer: A. 9.4 units

Step-by-step explanation:

       We could use the distance formula, but this problem asks us to use the Pythagorean theorem. This means we will "create" a right triangle and solve for the hypotenuse.

       [1] First, we need to draw our triangle.

-> Please see attached.

       [2] Now, we will count the length of the sides for the formula.

-> Please see attached.

       [3] Lastly, we can use the Pythagorean theorem to solve for the missing side which also known as the hypotenuse. In this case, it is from point R to point S

a² + b² = c²

5² + 8² = c²

25 + 64 = c²

89 = c²

[tex]\sqrt{89}[/tex] = c

c ≈ 9.43

-> Which becomes 9.4 when rounded to the tenths place.

Simplify using the rules of exponents:
b^4 x (b^2) ^6

A) b^12
B) b^48
C) b^16
D) b^68

Answers

Answer:

C

Step-by-step explanation:

Whenever you see a variable with an exponent (in parentheses) with another exponent (outside of the parentheses), you need to multiply them together.

[tex]2 \times 6 = 12[/tex]

Now that we only have b^4 x b^12, you might think we need to multiply the exponents again, but that would be wrong.

The only case where you should be multiplying exponents would be in the case of the first step.

Instead, we need to add them.

[tex] { b}^{4 + 12 = 16} [/tex]

Now we know our answer is C.

Given a right triangle with a leg of 8 and a hypotenuse of 17, what is the length of the other leg?

Answers

Pythagorean Theorem: a2+b2 = c2
where a, b are the sides of the right triangle and c is the hypotenuse

82 + x2 = 172 where x is the other side
x2 = 172 - 82
x2 = 289-64
x2 = 225
x = √225
x = 15

Answer:

a

Step-by-step explanation

bc the legs have 2 b shorter than the hypotenuse

Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).

This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:

2L+2W = 64

Now we know the area enclosed must be 252 so we have:

L* W = 252

Rewriting the second equation we get:

Plug this into first equation to get:

(multiply everything by L)

Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.

Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).
