What are the measures of angles A and C?

Answer:

0.555km p/h

shown as 555m  p/h

Step-by-step explanation:

First we convert km to meters

6k = 6000m

Time = distance / rate.

20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr

then 3.33 / 6 = 0.555 km  = 555 meters p/h

Answer: 38 is your answer hope this helped

plz make brainly

Step-by-step explanation:

Answer:

Add up the area of all the sides

Step-by-step explanation:

Surface area is the shell of a 3d shape, not the volume so you add the outside of the shape.

Hope this helps! :)

Answer:

1. Multiply the area by 2 and divide the result by the central angle in radians.

2. Find the square root of this division.

3. Multiply this root by the central angle again to get the arc length.

Step-by-step explanation:

Answer:

(x−1)(x+2)

Step-by-step explanation:

The middle number is 1 (1x) and the last number is -2.

Factoring means we want something like

(x+_)(x+_)  

We need two numbers that...

Add together to get 1

Multiply together to get -2  

Try -1 and 2:

-1+2 = 1

-1*2 = -2

Fill in the blanks in

(x+_)(x+_)

with -1 and 2 to get...

(x-1)(x+2)

Hope this helps!

A) First, find the volume of each cube:

V = s³

  = (1/2)³

  = 1/8 ft³

We have a total of 64 cubes, therefore the maximum volume will be:

Vmax = 64 · (1/8) = 8 ft³

B) The volume of a rectangular prism is given by:

V = w × l × h

Therefore any combination of w × l × h = Vmax = 8 will be fine.

Examples:

2 × 2 × 2

4 × 2 × 1

Answer:

The equation of line is

[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]

Step-by-step explanation:

The general equation of line is given as

[tex]y=mx+b[/tex]

where

y is the dependent variable which is yield in this case.

x is the independent variable which is fertilizer in this case

m is the coefficient of the fertilizer whose value is 1.150 from the given values.

b is the constant whole value is 10.100 from the given values.

Thus the equation becomes.

[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]

Answer:

x = 5, y = 5

Step-by-step explanation:

The scale changes from 8 to x+y

to find the change in scale, use the bottom values.

2 + 3 = 5 | 1 + 3 = 4

5/4 = 1.25 (the scale)

8 * 1.25 = 10

x+y = 10

There are 2 possibilities for this, but I feel like it is possibility #1

1. x = 5, y = 5

2. x = 4, y = 6

Answer: 10%

Step-by-step explanation:

Since the shopkeeper purchased 60 pencil boxes for 4,500, he purchased them at the rate of:

= 4500 / 60

= 85 per pencil box

If the shopkeeper sold them at the rate of 4,125 for 50 pencil boxes, then he sold them at the rate of:

= 4125 / 50

= 82.50 per pencil box.

Therefore the percentage profit will be:

= Gain / Cost price × 100

= (82.50 - 75) / 75 × 100

= 7.5/75 × 100

= 10%

Answer:

Answer:

Yes, the limit does exist.

Step-by-step explanation:

By definition, a limit in the form:

[tex]\displaystyle \lim_{x\to a}f(x)[/tex]

Exists if and only if:

[tex]\displaystyle \lim_{x\to a^-}f(x)=\lim_{x\to a^+}f(x)[/tex]

We are given the limit:

[tex]\displaystyle \lim_{x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]

So, in order to prove that this limit exists, we simply have to show that:

[tex]\displaystyle \lim_{x\to 2^-}\frac{x^2+x-6}{x^2-4}=\displaystyle \lim_{x\to 2^+}\frac{x^2+x-6}{x^2-4}[/tex]

Let's do the left-hand side first. We can factor the function:

[tex]=\displaystyle \lim_{x\to 2^-}\frac{(x+3)(x-2)}{(x+2)(x-2)}[/tex]

Simplify:

[tex]\displaystyle =\lim_{x\to 2^-}\frac{x+3}{x+2}[/tex]

By direct substitution:

[tex]\displaystyle =\frac{(2)+3}{(2)+2}=\frac{5}{4}[/tex]

Now, we can evaluate the right-hand side. Again, factor:

[tex]=\displaystyle \lim_{x\to 2^+}\frac{(x+3)(x-2)}{(x+2)(x-2)}[/tex]

Simplify:

[tex]\displaystyle =\lim_{x\to 2^+}\frac{x+3}{x+2}[/tex]

And by direct substitution:

[tex]\displaystyle =\frac{(2)+3}{(2)+2}=\frac{5}{4}[/tex]

Since both the left- and right-hand limits equal 5/4, our original limit does indeed exist.

Answer:

[tex] \huge \purple{ \boxed{ y = \frac{2}{3} }}[/tex]

Step-by-step explanation:

Since, the variables x and y are inversely proportional.

[tex] \therefore \: y \: \: \alpha \: \: \frac{1}{x} \\ \implies \: y = \frac{k}{x} \\ (k = constant) \\ \implies \: xy = k ...(1)\\ plug \: y = 2, \: \: x = 3 \: in \: equation \: (1) \\ we \: find \\ 2 \times 3 = k \\ k = 6 \\ plug \:k = 6 \: in \: equation \: (1) \\ xy = 6 \\ (this \: is \: the \: equation \: of \: variation) \\ when \: x = 9 \: \: y =? \\ \\ 9y = 6 \\ y = \frac{6}{9} \\ \huge \red{ \boxed{ y = \frac{2}{3} }}[/tex]

Answer:

9 - 11 = -2

Step-by-step explanation:

Because 9 is being subtracted by a number greater than itself, the answer has to be a negative and because:

9 + 2 = 11

9 - 11 = (-2)

Answer:

[tex]f^{-1}(x) = (x + 8)^2[/tex]

[tex]x \ge -8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \sqrt x - 8[/tex]

Solving (a): [tex]f^{-1}(x)[/tex]

We have:

[tex]f(x) = \sqrt x - 8[/tex]

Express f(x) as y

[tex]y = \sqrt x - 8[/tex]

Swap x and y

[tex]x = \sqrt y - 8[/tex]

Add 8 to [tex]both\ sides[/tex]

[tex]x + 8 = \sqrt y - 8 + 8[/tex]

[tex]x + 8 = \sqrt y[/tex]

Square both sides

[tex](x + 8)^2 = y[/tex]

Rewrite as:

[tex]y = (x + 8)^2[/tex]

Express y as: [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x) = (x + 8)^2[/tex]

To determine the domain, we have:

The original function is [tex]f(x) = \sqrt x - 8[/tex]

The range of this is: [tex]f(x) \ge -8[/tex]

The [tex]domain[/tex] of the [tex]inverse[/tex] function is the [tex]range[/tex] of the [tex]original[/tex] function.

Hence, the domain is:

[tex]x \ge -8[/tex]

Answer:

4 mins more would be  taken by Ellina

Step-by-step explanation:

Given that

Jasleen answers 4 questions every 30 seconds

And, Ella answers 5 questions every 40 seconds

And, last week Jasleen took exactly 1 hour for answering a large set of questions

We need to find out the number of more minutes taken by Ella

As Jasleen answers four questions every 30 seconds

So, Jasleen answers  8 questions for every 1 minutes

Now

Jasleen answers time taken

=  60 × 8

= 480 questions for every 60 minutes  or 1hr

On the other hand

Ella answers five questions every 40 seconds.

So, 1 questions in 8 sec

Now for 480 Questions , it would take

= 480 × 8 secs

= 480  × 8  ÷ 60  min

= 8 × 8

= 64 mins

Hence 4 mins more would be  taken by Ellina
