What is the value of x?

Westkost [7]

Answer:

x is equal to 20 in this picture.

Step-by-step explanation:

In order to find this, we need to note that these two angles will be equal to each other. Now we can put their values equal to each other and solve for x.

3x + 50 = 6x - 10

50 = 3x - 10

60 = 3x

20 = x

The length of a bacterial cell is about 3 x 10−6 m, and the length of an amoeba cell is about 4.5 x 10−4 m. How many times small

IrinaVladis [17]

The bacterial cell is 6.67 x 10⁻³ times smaller than the amoeba cell.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the length of a bacterial cell is about 3 x 10⁻⁶ m, and the length of an amoeba cell is about 4.5 x 10−⁻⁴ m.

The size of the cell will be calculated as below:-

B / A = ( 3 x 10⁻⁶ m ) / ( 4.5 x 10−⁻⁴ m )

B / A = 6.67 x 10⁻³

Therefore, the bacterial cell is 6.67 x 10⁻³ times smaller than the amoeba cell.

The cost to print digital photos at a local store is

snow_tiger [21]

<h2>The cost is same for both the options if we purchase 27 photos</h2>

Step-by-step explanation:

Cost of a photo at a local store is $0.25 per photo. This cost can be modeled to be linear in number of photos as $C_{1}(x)=0.25x$ .

Cost of photos purchased online is $0.15 per photo. However there is a shipping cost of $2.70. This can also be modeled to be linear in number of photos as $C_{2}(x)=2.70+0.15x$ .
