Answers

Answer:

D

Step-by-step explanation:

The problem is put in different fractions to make it more confusing.

1 1/15 miles+ 1 3/5 miles+ 1 2/3 miles

We can find the common denominator of all of the fractions.

[tex]1 \frac{1}{15} + 1 \frac{9}{15} + 1 \frac{10}{15} \\= 3+\frac{20}{15} =4 \frac{5}{15}\\\\=[/tex]4  1/3

given:

[tex]monday = 1 \frac{1}{15} [/tex]

[tex]tuesday = 1 \frac{3}{5} [/tex]

[tex]wednesday = 1 \frac{2}{3} [/tex]

to find:

the total number of miles Kenya ran in 3 days.

solution:

[tex] \frac{16}{15} + \frac{8}{5} + \frac{5}{3} [/tex]

[tex] = \frac{16}{15} + \frac{8 \times 3}{5 \times 3} + \frac{5 \times 5}{3 \times 5} [/tex]

[tex] = \frac{16 + 24 + 25}{15} [/tex]

[tex] = \frac{65}{15} = \frac{13}{3} [/tex]

[tex] = 4 \frac{1}{3} [/tex]

therefore, the correct answer is option D.

The diameter of a wheel is 150 cm, if the wheel travels 376.8 m, how many times does the wheel rotate?

Answers

Answer:

79.94

Step-by-step explanation:

First, let us find the circumference of the wheel (circle).

For that, let us use the below formula.

C = π × d

Given that,

d ⇒ diameter ⇒ 150 cm ⇒ 1.5 m

Let us find now.

C = π d

C = 3.142 × 1.5

C = 4.713

And now to find the number of times that the wheel rotates, you have to divide the total distance that wheel traveled by it's circumference.

Let us find now.

No. of times that wheel rotates = 376.8m ÷ 4.713m

No. of times that wheel rotates = 79.94

Approximately, the wheel will rotates 80 times.

Answers

Answer:

the last answer is correct, lim as it aproaches 33- is -6, and as it aproaches 33+ is -15

Step-by-step explanation:

The limit as the function approaches 33+ means the limit as the function approaches 33 from the right side, and the table shows it approaches 15 from x is above 33.

When x is slightly below 33, it aproaches -6.

The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,

⇒ - 6 and 15

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

Table shown the relation between x and g (x).

Now, By table we get;

At x = 32.999;

g (x) = - 6.01

At x = 33.001;

g (x) = - 15.01

Thus, The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,

⇒ - 6 and 15

The triangle is formed by placing a line directly from the y-axis to the x-axis.

The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].

your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.

Your coordinates for B are (100;0)
