URGENT !! I NEED HELP PLS

Answer:

Total tickets = 70

Total cost = $550

Adult's ticket = $9

Child's ticket = $5

Difference = 9 - 5 = $4

Assume all 70 are child's tickets

5 x 70 = 350

But the total cost was 550

550 - 350 = $200

The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50

So there are 50 adult's tickets.

70 - 50 = 20

And there are 20 child's tickets.

Answer:

950 km

Step-by-step explanation:

1 cm = 250 km

3.8 * 250  = 950

Answer:

950 km

Step-by-step explanation:

[tex]\frac{1}{250} = \frac{3.8}{x}[/tex]

(cross multiply)

250(3.8)= 950

(divide both sides by 1)

950/1=950

Answer:

4/5

Step-by-step explanation:

There are four quadrants in a coordinate geometry.

The value of cos(A - B) is 84/85

The given parameters are:

[tex]\mathbf{cos(A) = \frac{15}{17}}[/tex]

[tex]\mathbf{cos(B) = \frac{4}{5}}[/tex]

Using trigonometry ratio, we have:

[tex]\mathbf{sin^2(A) + cos^2(A)= 1}[/tex]

Substitute [tex]\mathbf{cos(A) = \frac{15}{17}}[/tex]

[tex]\mathbf{sin^2(A) + (\frac {15}{17})^2 =1}[/tex]

Expand

[tex]\mathbf{sin^2(A) + \frac{225}{289} =1}[/tex]

Collect like terms

[tex]\mathbf{sin^2(A) =1 - \frac{225}{289}}[/tex]

Evaluate fraction

[tex]\mathbf{sin^2(A) =\frac{64}{289}}[/tex]

Take square roots of both sides

[tex]\mathbf{sin(A) =\pm\frac{8}{17}}[/tex]

The angle is in the fourth quadrant.

So, we have:

[tex]\mathbf{sin(A) =-\frac{8}{17}}[/tex]

Also,

Substitute [tex]\mathbf{cos(B) = \frac{4}{5}}[/tex] in [tex]\mathbf{sin^2(B) + cos^2(B)= 1}[/tex]

[tex]\mathbf{sin^2(B) + (\frac 45)^2= 1}[/tex]

[tex]\mathbf{sin^2(B) + \frac{16}{25}= 1}[/tex]

Collect like terms

[tex]\mathbf{sin^2(B) = 1 - \frac{16}{25}}[/tex]

Simplify fraction

[tex]\mathbf{sin^2(B) = \frac{9}{25}}[/tex]

Take square roots

[tex]\mathbf{sin(B) = \pm \frac{3}{5}}[/tex]

The angle is also in fourth quadrant

So, we have:

[tex]\mathbf{sin(B) = - \frac{3}{5}}[/tex]

To calculate cos(A - B), we make use of:

[tex]\mathbf{cos(A - B) = cos(A)cos(B) + sin(A)sin(B)}[/tex]

So, we have:

[tex]\mathbf{cos(A - B) = \frac{15}{17} \times \frac{4}{5} + \frac{-8}{17} \times \frac{-3}{5}}[/tex]

Evaluate

[tex]\mathbf{cos(A - B) = \frac{60}{85} + \frac{24}{85}}[/tex]

Take LCM

[tex]\mathbf{cos(A - B) = \frac{60+24}{85}}[/tex]

[tex]\mathbf{cos(A - B) = \frac{84}{85}}[/tex]

Hence, the value of cos(A - B) is 84/85

Answer:

x = -4

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

x + 13 = 9

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 9 does indeed equal 9.

∴ x = -4 is a solution of the equation.

Answer:

x=-4

Step-by-step explanation:

So when solving a one-step algebraic equation you need to remember what you do to one side you have to do to the other side. In the problem x + 13 = 9 you need to subtract 13 from both sides to isolate x. So your problem should look like x = 9 - 13. Now all you have to do is solve 9 - 13 which is -4. So x = -4.

I hope this helped.

Answer:

R = 2524 quarts/s

Step-by-step explanation:

Water flows through a pipe at a rate of 8600 cubic meters per hour.

We know that,

1 m³ = 1056.69 quarts

1 hour = 3600 s

Rate of flow of water = 8600 cubic meters per hour

[tex]R=8600\ \dfrac{m^3}{h}\\\\=8600\times \dfrac{1056.69\ \text{quarts}}{3600\ s}\\\\=2524.311\ \text{quarts/s}[/tex]

or

R = 2524 quarts/s

So, the rate of flow of water is 2524 quarts/s.

Answer:

the cafe served 6 regular coffees

Step-by-step explanation:

to get your answer you can multiply the percentage times the amount served in total

Total regular coffees served = 6.

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given,

Total coffees served = 20

No. of regular coffees = 30% of 20

                                     = 30/100 × 20

No. of regular coffees = 6

Hence, Kelly's café served 6 regular coffees.

-4/9 is a rational number

Step-by-step explanation:

Rational numbers are the numbers you can make by dividing one integer by another, so in other words a fraction.

Answer

4/9 belongs to rational numbers (D).

Explanation

(Lol moderator deleted everyone's answers so I'm gonna answer).

First I'll give you a definition of each choice.

Integers: Integers don't include decimals or fractions. Integers are positive and negative numbers. So basically it's this; (..., -3, -2, -1, 0, 1, 2, 3, ...). The '...' means numbers from infinity to the next number. I hope this makes sense Imao.

Whole numbers: whole numbers are integers, except they don't include negative numbers. Whole numbers include 0 (zero)... (0, 1, 2, 3, ...)

Natural numbers: natural numbers are whole numbers but they don't include 0 (zero)... (1, 2, 3, ...)

Rational numbers: rational numbers are numbers that can be expressed as a fraction. This includes repeating decimals such as 0.333 repeating. Rational numbers also include integers, because if you put the number over one, that is a fraction. Rational numbers are basically every number except for the radicals of some numbers (such as the square root of 3) and pi.

So now let's just see which one 4/9 is.

Well, 4/9 is not an integer, whole number, or natural number because it is a fraction.

But 4/9 can be expressed as a fraction (well, it already is one) meaning it is a rational number.

You graph it here

Answer:

Step-by-step explanation:

Alright, so this is basically just another equation, but then you see the greater than or equal to sign. How do I solve this? You may be asking. Well, treat it like an equation and worry about the sign later.

4x - 5 [tex]\geq[/tex] 7

Solve for x.

Add 5 to each side, then divide by 4 to each side.

4x [tex]\geq[/tex] 12

x [tex]\geq[/tex] 3  <----This is the answer.

Now for the graph. Look at the picture below:

That's what the graph should look like. Since it has a greater than or equal to sign, the line will be solid.

The graph is basically saying that anything that is greater than 3 (including 3) is counted, which is why that entire right side of 3 is shaded in.

Also, the way you should technically graph it is on a number line. So make a number line.

     -2   -1     0     1     2    3     4     5    6    7     8    9    10

<-----|-----|-----|-----|-----|-----€-----|-----|-----|-----|-----|-----|-----|----->

(Pretend € is the filled in dot).

So, the above number line is what it should look like when graphed. The € circle is filled in because we are including the 3.
