Answer:

160

Step-by-step explanation:

you need to multiply the ounces of gas by 4 like you did to the oil.

Answer:

160 oz

Step-by-step explanation:

However, I personally think this does not make sense. A leaf blower should take more gas than oil, right? For this reason, I will provide an additional answer.

If the ratio of gas to oil is 40:1, then you would multiply by 4 to get 4 oz oil and 160 oz gas.

Alternate answer:

If the ratio of oil to gas is 40:1, then you divide by 10 on both sides to get 4 oz oil and .1 oz gas.

Alt answer: .1 oz

Answer: 1:21

Step-by-step explanation:

We know that if they say students they mean both boys and girls so we add 11 and 10 to make 21 and since its, (COACH,) and then student we do 1:21 and not 21:1!

1/21

Step-by-step explanation:

First we need to figure out how many students are in the class.

10 + 11 = 21

Then we need to make a ratio

1/21

For every 21 students there is 1 coach

If you look at the question it says from coach to students so we do 1 coach to 21 students which is why 21/1 is wrong

By analyzing the quadratic function, we can see that:

Here we have the quadratic function:

f(x) = (x + 6)*(x + 2)

Let's analyze each statement to see which ones are correct.

1) "The vertex is the maximum value."

True, the leading coefficient is positive, so the parabola opens up, meaning that the vertex is the minimum.

2) " The axis of symmetry is x= -4."

The two roots are x = -6 and x = -2, the axis of symmetry is right between these two values, so it is at x = -4, so this is true.

3) "The domain is all real numbers."

For all quadratic functions, this is true.

4) "The function is increasing over (-0, -4)"

(I don't know what -0 means, the segment (-0, -4) does not exist, so i will take this as false).

5) "The function is negative over (-6, -2)."

This is true, the two roots are at -6 and -2, so between these values the function must be negative.

Answer:

a=12 ft, b=12 ft

Step-by-step explanation:

-Length A and length B are equal since the right angle triangle is also an isosceles triangle.

-We use the Law of sines to calculate the two lengths:

[tex]\frac{a}{Sin \ A}=\frac{b}{Sin \ B}=\frac{12\sqrt{2}}{Sin\ 90\textdegree}\\\\a=b=12\sqrt{2} \ Sin \ 45\textdegree\\\\a=b=12\ ft[/tex]

Hence, length a is equal to length b which is equal to 12 ft

Answer:

1. M = C*1.018^t

After 15 years: M = 4965.93

2. After 3 years: M = 2249.728

After 18 years: M = 4051.633

Time to achieve 3000: t = 10.338 years

Step-by-step explanation:

1. Since the money gets increased every year at a rate of 1.8% after one year it'll be the initial amount multiplied by 1.018, so:

After one year:

M = C*1.018

After two years:

M = C*1.018*1.018 = C*(1.018)²

After three years:

M = C*(1.018)²*1.018 = C*(1.018)³

And so on, therefore:

M = C*(1.018)^t

Where M is the final amount, C is the initial amount and t is the time elapsed in years. For this case we have:

M = 3800(1.018)^15 = 4965.92626

2. Applying the same line of thought as above, we have:

M = C*(1.04)^t

After 3 years:

M = 2000*(1.04)^3 = 2249.728

After 18 years:

M = 2000*(1.04)^18 = 4051.633

To obtain 3000:

3000 = 2000*(1.04)^t

2000*(1.04)^t = 3000

1.04^t = 3000/2000

1.04^t =1.5

log(1.04^t) = log(1.5)

t*log(1.04) = log(1.5)

t = log(1.5)/log(1.04) = 10.338 years

Step-by-step explanation:

We can use the following formula to solve:

[tex]A=P(1-r)^t[/tex]

P = principal value

r = rate (decimal)

t = time (years)

First, change 9% into a decimal:

9% -> [tex]\frac{9}{100}[/tex] -> 0.09

Now, just plug the values into the equation:

NOTE: THIS IS AN EXAMPLE

Step-by-step explanation:

Let the Yellow Marbles be “X” and Red Marbles be “Y”

Total is 65, so X+Y = 65

Since we know that Yellow Marbles are 5 more than 4 times red marbles, let us convert that in terms of X and Y as well.

i.e, X = 4Y+5

Now replace X with (4Y+5) in the first equation we wrote above.

(4Y+5)+Y = 65

i.e, 5Y+5 = 65

5Y = (65–5),

5Y = 60

Therefore Y = 60/5 = 12

we know total is 65

So X= 65-Y

X=65–12 = 53

Therefore, the number of Yellow Marbles are 53 and the Red ones are 12.

Answer:

Frank, Vanessa, Lois have 34, 17, 64 disks respectively

Step-by-step explanation:

In this question, we are to calculate the number of disks each of the 3 has.

Let the number of disks owned by Frank be x

for vanessa, she has half of what frank has and that would be x/2

Lois has 4 less than 2 times what Frank has, that would be 2x - 4

adding the 3, we have a total of 115 disks

This means that;

x + x/2 + (2x-4) = 115

Multiply throughout by 2;

that gives;

2x + x + 4x - 8 = 230

7x -8 = 230

7x = 230+ 8

7x = 238

x = 238/7

x = 34 disks

Frank has 34

Vaness has 34/2 = 17

Lois have 2x - 4 = 2(34) - 4 = 68 - 4 = 64 disks

Answer:

So Frank has 34 CDs, Vanessa has 17 CD's and Lois has 64 CDs

Step-by-step explanation:

Let's call the amount of CDs that Frank has by 'F', that Vanessa has by 'V' and that Lois has by 'L'. Then, we can write the following equations:

F = 2*V

L = 2*F - 4

F + V + L = 115

If we use the values of F and L in the third equation, we have that:

2*V + V + 2*(2*V) - 4 = 115

7*V = 119

V = 17 CD's

Now we can find F:

F = 2*V = 34 CDs

And then we find L:

L = 2*F - 4 = 68 - 4 = 64 CDs

So Frank has 34 CDs, Vanessa has 17 CD's and Lois has 64 CDs

Answer :

The weight of a sedans in tons is 2.1 tons.

Step-by-step explanation:

Given : Equations [tex]T=s+0.50[/tex] and [tex]T=0.25s+1.70[/tex] where T and s represents the weight in tons of a sedan and of a truck, respectively.

To find : What is the weight of a sedan in tons ?

Solution :

Solving equations,

[tex]T=s+0.50[/tex] ......(1)

[tex]T=0.25s+1.70[/tex]  .....(2)

As LHS is equate we equate RHS,

[tex]s+0.50=0.25s+1.70[/tex]

[tex]s-0.25s=1.70-0.50[/tex]

[tex]0.75s=1.2[/tex]

[tex]s=\frac{1.2}{0.75}[/tex]

[tex]s=1.6[/tex]

Substitute in equation (1),

[tex]T=1.6+0.50[/tex]

[tex]T=2.1[/tex]

Therefore, the weight of a sedans in tons is 2.1 tons.

Answer:

2500 Square meters

Step-by-step explanation:

Given the garden area (as a function of its width) as:

[tex]A(w)=-w^2+100w[/tex]

The maximum possible area occurs when we maximize the area. To do this, we take the derivative, set it equal to zero and solve for w.

A'(w)=-2w+100

-2w+100=0

-2w=-100

w=50 meters

Since Marquise has 200 meters of fencing to build a rectangular garden,

Perimeter of the proposed garden=200 meters

Perimeter=2(l+w)

2(l+50)=200

2l+100=200

2l=200-100=100

l=50 meters

The dimensions that will yield the maximum area are therefore:

Length =50 meters

Width=50 meters

Maximum Area Possible =50 X 50 =2500 square meters.

Answer:

995 general admission tickets and 260 reserved seat tickets

Step-by-step explanation:

We can solve this by using Simultaneous equations.

General admission is $4.00 and each Reserved seat is $4.50.

Let g represent the number of General admission tickets and r represent the number of Reserved seat tickets.

The total amount paid for 1255 tickets is $5150.00.

This means two things:

1. The total number of tickets is 1255, which means if we add the general admission tickets and the number of reserved seat tickets, we will get 1255:

g + r = 1255 ________________ (1)

2. The total price of all tickets is $5150.00, which means if we multiply the number of general admission tickets by the price of general admission tickets and we multiply the number of reserved seat tickets by the price of reserved seat tickets and add them up, we will get $5150:

(4.00*g) + (4.50*r) = 5150 _________(2)

=> g + r = 1255 __________________(1)

   (4.00*g) + (4.50*r) = 5150  _________(2)

From (1):

g = 1255 - r _______ (3)

Putting (3) in (2):

{4.00*(1255 - r)} + (4.50*r) = 5150

5020 - 4.00r + 4.50r = 5150

5020 + 0.50r = 5150

=> 0.50r = 5150 - 5020

0.50r = 130

r = 130 / 0.50 = 260

Putting the value of r in (3):

g = 1255 - 260 = 995

Hence, 995 general admission tickets and 260 reserved seat tickets were sold.

Final answer:

To find the number of general admission and reserved seat tickets sold, set up and solve a system of equations using the given information.

Explanation:

Given:

General admission tickets cost $4.00.

Reserved seat tickets cost $4.50.

Total receipts were $5150.00 for 1255 paid admissions.

To solve:

Let x be the number of general admission tickets sold.

Let y be the number of reserved seat tickets sold.

Form the equations: x + y = 1255 and 4x + 4.50y = 5150.

Solve the system of equations to find x and y.

Answer: 705 general admission tickets and 550 reserved seat tickets were sold.
