Answer:

plz make it brainlisted

Step-by-step explanation:

Since the total is 300 and the ratio is 4:1,

Let us suppose the number of adults be 4x and children be x;

According to the question,

4x+x=300

or,5x=300

or,x=(300/5)

or,x=60

So, 60 students attended the show.

Answer:

75

Step-by-step explanation:

4:1 children meaning 1/4 of the population of 300 is 75

Answer:

When I did this in middle school, the teacher made it unnecessarily difficult     (-_-), so here`s my own method for you.

Finding 1%:

If 9 is 3%, then 3 is 1%. This method only works when the sides are divisible.

You can use the 1% to find the total, which is 100%.

3 stores (or 1%) x 100 = 300.

There are 300 stores in the shopping district.

Answer:

b

Step-by-step explanation:

It will take [tex]\frac{20}{9}[/tex] hours as per linear equation to complete the wall.

A linear equation is an equation where the variable of the equation has the highest power of degree one.

Given, the 1st bricklayer build a complete wall of certain size in 5 hours.

Therefore, that bricklayer build [tex]\frac{1}{5}[/tex]th of the complete wall in 1 hour.

Similarly, the 2nd bricklayer build a complete wall of certain size in 4 hours.

Therefore, that bricklayer build [tex]\frac{1}{4}[/tex]th of the complete wall in 1 hour.

If they work together, in 1 hour they build a total of ([tex]\frac{1}{5}[/tex]+[tex]\frac{1}{4}[/tex])th = [tex]\frac{9}{20}[/tex] of the complete wall.

Hence, they will complete the wall in (1÷[tex]\frac{9}{20}[/tex]) hours = [tex]\frac{20}{9}[/tex] hours.

Answer:

I would have to say 5/13 and if I'm wrong I'm sorry just trying to help you out

The question is incomplete. The complete question is :

A sine function that has an amplitude of 16 units, a period of 5 units,a vertical displacement of 3 units up and a phase shift of 2.5 units left. Graph this function and show each step.

Solution :

The standard form of the sine function is

y = a sin (bx - c) + d

Here given :

Amplitude, a = 16

Period :   [tex]$\frac{2 \pi}{|b|} = 5$[/tex]

            ⇒ [tex]$b = \frac{2\pi}{5}$[/tex]

Phase shift :  [tex]$\frac{c}{b} = 2.5$[/tex]

                   [tex]$\Rightarrow \frac{c}{2 \pi/5}=\frac{5}{2}$[/tex]

                  ∴ [tex]$c = - \pi$[/tex]

The vertical displacement : d = 3 units up

Now substituting a, b, c and d values in the standard form gives :

[tex]$y = 16 \sin \left( \frac{2 \pi}{5}x -(- \pi)\right) + 3$[/tex]

[tex]$y = 16 \sin \left( \frac{2 \pi}{5}x + \pi\right) + 3$[/tex]

The graph is attached below.

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

From the question we have

[tex]m = \frac{ - 22 - - 2}{ - 4 - - 4} = \frac{ - 22 + 2}{ - 4 + 4} = - \frac{20}{0} \\ [/tex]

Any number divided by zero is undefined so the slope of the line is undefined.

Hope this helps you

Answer:

Step-by-step Explanation:

We need to find the slope of the line joining the points (-4, -2) and (-4, -22).

We know that, Slope is the difference of abcsissa (x - coordinate) / difference of ordinates (y-coordinate)

[tex]m = \dfrac{y2 - y1}{x2 - x1} [/tex]

Here:

Plugging these values:

[tex]m = \dfrac{ - 22 - ( - 2)}{ - 4 - ( - 4)} [/tex]

This can be written as:

[tex]m = \dfrac{ - 22 + 2}{ - 4 + 4} [/tex]

[tex]m = \dfrac{ - 20}{0} = \infty [/tex]

Here, The slope of the line is infinite or undefined. An undefined slope (or an infinitely large slope) is the slope of a vertical line!

Answer:

1,000 miles

Step-by-step explanation:

set up the equation as

100x = d

where x equals the number of half inches between two points on the map

and d equals the distance between those points in real life

5 inches = 10 half inches so, plugged in the equation looks like

100(10) = d

simplify it to

1000 = d

and bam, the real distance is 1,000 miles

Answer:

9/40

Step-by-step explanation:

He needs 5/8, he already has 2/5, so still needed is 5/8-2/5.

To add or subtract fractions, the denominators must be equal.

Simplest approach is to multiply them. 8 times 5 is 40, so 40 is the new denominator we need for both fractions.

So first we convert 5/8 to 25/40.

Then we convert 2/5 to 16/40.

Now we can subtract them:

25/40 - 16/40 = 9/40.

9/40 cannot be simplified so this is the final answer.

Answer:

f(x) = -2x + 1

Step-by-step explanation:

Triangle ABC is a right triangle. The length of the legs are 3 in and 6 in, how long is the hypotenuse? (Round to the nearest tenth if necessary)

When the two legs are given, the hypotenuse is found by using the Pythagorean Theorem, which states that:

[tex]\displaystyle a^{2} +b^{2} =c^{2}[/tex]

In the theorem, a and b are the two legs, and c is the hypotenuse. Since you are given the length of the two legs, substitute it into the equation.

[tex]a=3\\b=6[/tex]

[tex]3^{2} +6^{2}=c^{2}[/tex]

Now, you need to square both 3 and 6. When you square a number, you're basically multiplying the number by itself.

[tex]3^{2} =3 \times 3=9\\6^{2}=6 \times 6=36[/tex]

Substitute the numbers into the equation.

[tex]9+36=c^{2}[/tex]

Add:

[tex]45=c^{2}[/tex]

You're looking for the value of c, not c squared. To remove the square, you need to square root it.

[tex]\displaystyle \sqrt{45}=\sqrt{c^{2} }[/tex]

Using a calculator, find the square root of 45.

[tex]\displaystyle \sqrt{45}=\sqrt{c^{2} }\\c \approx 6.7[/tex]

The answer to your question is B) 6.7 inches.

Answer: A

Step-by-step explanation:

Use Pythagorean Theorem in order to solve this:

[tex]a^{2} + b^{2} = c^{2}[/tex]

(c is the hypotenuse)

So that would be:

[tex]3^{2} + 6^{2} = c^{2}[/tex]

If you solve this, you would find that:

[tex]c^{2} = 45[/tex]

[tex]c = 3\sqrt{5}[/tex]
