how can i answered this​

Let the lawn seats purchased by the business be : L

Let the reserved seats purchased by the business be : R

Given :

⊕   Cost of each lawn seat : $10

⊕   Cost of each reserved seat : $25

⊕   Sponsoring business has given the $375 to purchase seats

⊕   School purchased 30 seats using all of the money

⇒   L + R = 30         ---------- (1)

⇒   10L + 25R = 375             ----------- (2)

Multiplying equation (1) with 10, we get :

⇒   10L + 10R = 300       ------------- (3)

Subtracting equation (3) from equation (2), we get :

⇒   10L + 25R - (10L - 10R) = 375 - 300

⇒   25R - 10R = 75

⇒   15R = 75

⇒   R = 5

Substituting R = 5 in equation (1), we get :

⇒   L + 5 = 30

⇒   L = 25

Answer: The Business purchased 25 lawn seats and 5 reserved seats

Answer:

253.90

Step-by-step explanation:

Answer:

For each unit increase in x ; y decreases by 2 units.

Step-by-step explanation:

A negative relationship between two variables, X and Y is depicted d on a scatter plot by a negative trend line or slope. A negative relationship is interpreted as the decrease in variable X as Y increases or vice versa.

The scatter plot attached is related by the linear model :

y = - 2x + 110

Here, the slope of the plot is - 2 ; this means that for every unit increase in x - axis, then the y values decrease by 2 units.

Answer:

[tex]Area = 138in^2[/tex]

Step-by-step explanation:

Given

[tex]L = 9; W =3; H =3\frac{1}{2}[/tex]

Required

The surface area

This is calculated as:

[tex]Area = 2(LW + LH + WH)[/tex]

So:

[tex]Area = 2(9*3 + 9*3\frac{1}{2} + 3*3\frac{1}{2})[/tex]

[tex]Area = 2(27 + 31\frac{1}{2} + 10\frac{1}{2})[/tex]

[tex]Area = 2*69[/tex]

[tex]Area = 138in^2[/tex]

Answer:

60 different permutations of these letters can be made.

Step-by-step explanation:

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

How many different permutations of these letters can be made if no letter is used more than once?

3 letters from a set of 5. So

[tex]P_{(5,3)} = \frac{5!}{(5-3)!} = \frac{5!}{2!} = 5*4*3 = 60[/tex]

60 different permutations of these letters can be made.

Answer:

<V = 40

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

20x = 60+7x+5

Combine like terms

20x = 7x+65

Subtract 7x from each side

20x -7x = 7x+65-7x

13x = 65

Divide each side by 13

13x/13 = 65/13

x = 5

<v = 7x+5 = 7*5+5 = 35+5 = 40

answer:

it's U = 60°

V = 50°

T = 70°

Answer:

6

Step-by-step explanation:

In a circle equation, the radius can be found by taking the square root of the r² value.

In this equation, the r² value is 36.

Take the square root:

√36

= 6

So, the radius is 6.

Step-by-step explanation:

the other answer is correct.

just for a little bit of explanation :

the first position after the decimal point is for tenths. the second position for hundredths. the third for thousandths. then ten-thousandths, hundred-thousandths, millionths, ...

so, you would need 1000 thousandths to have a 1 at the first position before the decimal point. everything less than that has to be a number after the decimal point. and thousandths have to end (writing from left to right) with the thousandths-position. hundredths with the hundredths-position and so on.

Answer:

1.5

Step-by-step explanation:

Let's begin by dividing each side by 4.

You get 18/4 or 4.5.

m+3=4.5

Now subtract 3 to each side.

m=1.5

Answer:

[tex]4(m + 3) = 18 \\ 2(m + 3) = 9 \\ 2m + 6 = 9 \\ 2m = 3 \\ m = \frac{3}{2} \\ m = 1.5[/tex]

Answer:

The speed is 60 mph.

Step-by-step explanation:

distance = 42 miles

Let he drove with speed v and time is t.

distance = speed x time

42 = v t ..... (1)

42 = (v + 10)(t - 1/10) ..... (2)

[tex]42 = 42 -\frac{v}{10}+ 10 t - 1\\\\t =\frac{10+v}{100}\\\\Put in (1)\\\\42 = \frac{v(10+v)}{100}\\\\v^2 + 10 v - 4200 = 0 \\\\v = \frac{-10\pm \sqrt{100+4\times 4200}}{2}\\\\v =\frac{- 10 \pm 130}{2}\\\\v =- 70 mph, 60mph[/tex]

So, the speed cannot be negative so the speed is 60 mph.

Step-by-step explanation:

If there are 3 red marbles, 5 green marbles, and 2 blue marbles, we can find the probability of finding one of them easily.

1. If we add these numbers up, we get 10, so the red marbles plus the green marbles = 8 and then there are 2 blue ones. This means that there is an 80% chance of pulling a red or a green marble. Number one is correct.

2. The probability of drawing a red marble followed by a green marble depends on each individual probability. For a red marble, that is [tex]\frac{3}{10}[/tex] = 30% chance, and a green marble is [tex]\frac{5}{10}[/tex] = 50% chance. Since we are drawing out of 20 marbles (Two sets of ten), we can conclude that the chances for red are [tex]\frac{6}{20}[/tex]; green's chances are [tex]\frac{10}{20}[/tex], and blue's chances are [tex]\frac{4}{20}[/tex]. Assuming that we draw a red marble first, there is a [tex]\frac{6}{20}[/tex] chance of that. There is a [tex]\frac{10}{20}[/tex] chance of drawing a green, so we can conclude that the probability of drawing a red marble followed by a green marble is [tex]\frac{4}{20}[/tex] ([tex]\frac{10}{20}[/tex] - [tex]\frac{6}{20}[/tex]), witch is not [tex]\frac{1}{6}[/tex]. Number two is incorrect .

3. The probability of drawing a blue marble is 20%, so the probability of not drawing a blue marble is 80%. Number three is incorrect.

4. The probability of drawing a green marble is 50% and the probabilities of red and blue combined are equal to 50% (3 red + 2 blue = 5, and their are 5 green marbles therefore 50 50 chance). Number four is correct.

Answer:

The probability of randomly drawing a red marble(red 3) and then a green (green 5) marble is [tex]\frac{1}{6}[/tex] .

The probability of drawing a green marble is the same as the probability of drawing either a red or a blue marble.

The probability of randomly drawing either a red marble or a green marble is 80%.

Answer:

idfk lol hehe hope this helps

Step-by-step explanation:

Answer:

0.0181 = 1.81% probability of drawing a suit first, and then a face card.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of drawing a suit first:

4 out of 52 cards are suits, so:

[tex]P(A) = \frac{4}{52} = \frac{1}{13}[/tex]

Followed by drawing a face card:

Considering a suit was drawn, there will be 12 faces in the 51 remaining cards. So

[tex]P(B|A) = \frac{12}{51}[/tex]

What is the probability of drawing a suit first, followed by drawing a face card?

[tex]P(A \cap B) = P(A) \times P(B|A) = \frac{1}{13} \times \frac{12}{51} = \frac{12}{13*51} = 0.0181[/tex]

0.0181 = 1.81% probability of drawing a suit first, and then a face card.

Answer:

5940

Step-by-step explanation:

The first '6' represents '6000' and the second represents '60.'

Thus the difference of the values of the two '6s' is 6000 - 60 = 5940.

Answer:

12.4

Step-by-step explanation:

to get radius divide diameter by 2

9514 1404 393

Answer:

  49.3 feet

Step-by-step explanation:

Shadow lengths and object heights are considered to be proportional, so we have ...

  tree height/(tree shadow) = Andrew's height/(Andrew's shadow)

  height / (85 ft) = (5.8 ft)/(10 ft)

  height = (85 ft)(5.8/10) = 49.3 ft

The tree is 49.3 feet tall.
