Answer: 2^16

Step-by-step explanation:

1. Since its asking for an exponent with a base of 2 turn all the numbers into exponents with the base of 2

16 x 4^3 x 64 -> (2^4) x ((2^2)^3) x (2^6)

2. Use the law of exponents to simplify

*if x, a, and b are variables then...

(x^a)^b -> x^(a*b)

x^a * x^b -> x^ (a+b)

(2^4) x ((2^2)^3) x (2^6)

= (2^4) x (2^(2*3)) x (2^6)

= (2^4) x (2^6) x (2^6)

= (2^(4+6)) x (2^6)

= 2^(10) x (2^6)

= 2^(10+6)

= 2^16

Answer:

2 Sig Figs

Step-by-step explanation:

6 is a significant number (a non-zero). It counts as one sig fig.

Any zero after the decimal is significant. It also counts as one sig fig.

One sig fig + one sig fig = 2 sig figs.

Answer: 2

There are 10 triangles, that represent the number 2. There are 8 circles, that represents the number 1. To make this 1:1, we must add 2 circles.

10:10 = 1:1

The answer to the question is 2 circles.

Hope this helps you!

The number of circles is two that need to be added to make the ratio 1:1

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Given that,

The ratio of the number of circles to the number of triangles in simplest form is 2 : 14

The number 2 is represented by the ten triangles that are visible.

The number 1 is represented by the 8 circles.

So the number of two circles that must be added to get a ratio of 1:1,

Therefore two circles must be added.

Hence, the number of circles is two that need to be added to make the ratio 1:1

Answer:

Simplifying

9 + -3x = y

Solving

9 + -3x = y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + -3x = -9 + y

Combine like terms: 9 + -9 = 0

0 + -3x = -9 + y

-3x = -9 + y

Divide each side by '-3'.

x = 3 + -0.3333333333y

Simplifying

x = 3 + -0.3333333333y

Answer:

y = -1x - 1

Step-by-step explanation:

y = mx + b

Find slope:

m = (y₂ - y₁) / (x₂ - x₁)

   = (3-(-3)) / (-4-2)

   = 6 / -6

m = -1

Find b:

Pick anyone of the two coordinates. Let's use (2, -3).

y = mx + b

-3 = -1(2) + b

-3 = -2 + b

b = -1

Use m and b from above steps to make equation.

y = mx + b

y = -1x - 1

Overdrafting is when you deposit you're money in a bank account so it could either be +75 or -75 both of them might be correct.

The absolute value of Michaels's account overdraft of $75 will be 75.

Absolute values are the value of any digit without considering the sign.

So all negative values will be considered positive for absolute value.

For example, the absolute value of -2 will be 2 and the absolute value of -7 will be 7.

Given the overdrafts of $75.00

The absolute value of $75.00 will be 75 because it is not negative it is a positive quantity.

Hence "The absolute value of Michaels's account overdraft of $75 will be 75".

Step-by-step explanation:

bowling balls without holes = 77  and 35%

find: how many bowling balls in the store?

let x be the total

its a ratio and proportion:

 77   =     x      

 35        100

cross multiply:

35 (x) = 77 (100)

x = 7700 / 35

x = 220   ------>> total number of balls in the store

77 bowling balls without holes are available in a store that sells bowling supplies. 220 bowling balls will be available in the store if 35% of the balls do not have holes.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Given that, there are 77 bowling balls in the bowling alley that don't have holes drilled in them. 35 percent of bowling balls are black holes.

Bowling balls without holes = 77  and 35%

let x be the total its a ratio and proportion:

77/35 = x/100

35 (x) = 77 (100)

x = 7700 / 35

x = 220  

Thus, 77 bowling balls without holes are available in a store that sells bowling supplies. 220 bowling balls will be available in the store if 35% of the balls do not have holes.
