Answer: adults = $10

Step-by-step explanation:

x = adults

y = children

2x + 2y = 30

2x + 3y = 35

Using the elimination method:

2x + 2y = 30

-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)

Solve for y...

2y = 30

-3y = -35

Add together...

-y = -5

Multiply by -1 to give positive value for y...

y = $5

Plug into one of the original equation to find x...

2x + 10 = 30

2x = 20

x = $10

Answer:

5.50 + 0.88r ≤ 26.00; 24 rides

or 5.50 + 0.88r ≤ 26.00; 23 rides

Step-by-step explanation:

mrk me brainliest plz

i can't explain it i just look at a math problem and auotomatically know the answer

Answer:

(1) 5.50 + 0.88r ≤ 26.00; 23 rides

Step-by-step explanation:

First of all, please understand the equation itself. We are multiplying 0.88 by r, or the number of rides. First, lets determine how many rides Elisha can ride. 0.88 * 23 = 20.24. And 20.24 + 5.50 = 25.74. This is less than 26.00. Now, 0.88 * 24 = 21.12 + 5.50 = 26.7. Though not by much, this is more than 26.00, so, Elisha cannot ride more than 23 rides. That eliminates options (3) and (4). The difference between (1) and (2) is that in (1) we are multiplying 0.88 by r which is correct, however, option (2) is multiplying 5.50 by r which is incorrect. Thus we have our answer. However, please note one important thing. I want you to understand the reason for the "≤" sign as this is very different from <. The sign used here indicates "less than OR equal to" whereas the other is "less than." The sign used indicates that this is the MAX Elisha can spend but he could also spend less. This may seem simple but it is crucial to have a good understanding of this concept as you progress. Any further questions just comment! Hope this helps:) P.S. do not just take the answer! READ, PRACTICE, AND UNDERSTAND.

Answer:

Typically, volume is used to measure the capacity of a container/bottle/etc. It is used alongside measurements for liquids, like mL or L.

Step-by-step explanation:

first we will find angle BED = 180 - 49 = 131 degrees

then find angle BDE = 90 - 64 = 26

then subtract the sum of both from 180

180-26+131=23 degrees

Answer:

Since each card is about $1, the total cost is approximately 3 × 1 = $3.

Step-by-step explanation:

So 3 x 1 = 3

1 > 0.97

0.97 x 3 ≈ 2.91 which if rounded to the nearest WHOLE number it would be approximately 3$

Answer:

The other integer is less than -80

Step-by-step explanation:

The given sum of the two integers < -57

The value of one of the integers = 23

Let 'b' represent the value of the other integer, we are given;

b + 23 < -57

Therefore, we have;

b < -57 - 23 = -80

Therefore, the other integer, b < -80.

Answer:

y = -2x + 150

Step-by-step explanation:

y2 - y1 / x2 - x1

120 - 100 / 15 - 25

20 / -10

= -2

y = -2x + b

100 = -2(25) + b

100 = -50 + b

150 = b

Answer:

[tex]BD = 30[/tex]

Step-by-step explanation:

Given

[tex]AB = 17[/tex]

[tex]AC = 16[/tex]

See attachment

Required

Find BD

If AC = 16, then:

[tex]AO = 16/2[/tex] i.e. half the diagonal AC

[tex]AO = 8[/tex]

The diagonals of a rhombus are perpendicular.

This implies that we can apply Pythagoras theorem.

Using Pythagoras theorem on triangle AOB, we have:

[tex]AB^2 = AO^2 + OB^2[/tex]

[tex]17^2 = 8^2 + OB^2[/tex]

[tex]289 = 64 + OB^2[/tex]

Collect like terms

[tex]OB^2 = 289 - 64[/tex]

[tex]OB^2 = 225[/tex]

Take positive square roots of both sides

[tex]OB = 15[/tex]

To solve for BD, we use:

[tex]OB = \frac{BD}{2}[/tex] --- i.e. half the diagonal BD

[tex]BD = 2 * OB[/tex]

[tex]BD = 2 * 15[/tex]

[tex]BD = 30[/tex]

Answer:

a) $3.50

b) 2,500 cups

c) $6,250

Step-by-step explanation:

a) The number of cups of coffee the student sells, n = 2,000 cups

The price at which the student sells the coffee, P = $4.0

The number of extra cups sold for every $0.1 reduction in price = 100 cups

The cost of making one cup of coffee, C = $1.0

Let 'x' represent the set charge for a cup of coffee, we get;

The number of cups, nₙ = 2,000 + 100 × (4.0 - x)/0.1 = 6,000 - 1,000·x

Therefore, the revenue is given as follows;

Revenue, R = x × (6,000 - 1,000·x) = 6000·x - 1,000·x² = 1,000·(6·x - x²)

The cost, C = 1 × 6,000 - 1,000·x = 6,000 - 1,000·x

The profit, P = Revenue - Cost

∴ Profit = 6000·x - 1,000·x² - (6,000 - 1,000·x) = 7,000·x - 1,000·x² - 6,000

Profit, P = 7,000·x - 1,000·x² - 6,000 = 1,000 × (7·x - x² - 6)

At the maximum profit, we have; , we have;

dP/dx = 0

∴ dP/dx = d(1,000 × (7·x - x² - 6))/d

dR/dx = 1,000·d(7·x - x² - 6)/dx = 1,000 × (7 - 2·x) = 0

x = 7/2 = 3.5

The price that gives the maximum profit, x = $3.50

Therefore, the amount the student center should charge for a cup of coffee to maximize profit, x = $3.50

b) We have;

The number of cups, n = 6,000 - 1,000 × 3.5 = 2,500

The number of cups of coffee the student center sells at the price that gives the maximum profit, n = 2,500 cups

c) The maximum profit, [tex]P_{max}[/tex] = 1,000 × (7 × 3.5 - 3.5² - 6) = 6,250

The maximum profit, [tex]P_{max}[/tex] = $6,250.
