Step-by-step explanation:

The second event is dependent on the first.

Answer:

Maximum revenue is 11200 at price p=10.

Step-by-step explanation:

If a quadratic function is defined by [tex]f(x)=ax^2+bx+c[/tex] and a<0, then it is maximum at [tex](\frac{-b}{2a},f(\frac{-b}{2a}))[/tex].

The revenue model of a company is

[tex]R=-12p^2+240p+10,000[/tex]

Here, [tex]a=-12, b=240,c=10000[/tex].

So,

[tex]-\dfrac{b}{2a}=-\dfrac{240}{2(-12)}=10[/tex]

It means, revenue is maximum at price 10.

Substitute p=10 in the revenue function.

[tex]R=-12(10)^2+240(10)+10000[/tex]

[tex]R=-1200+2400+10,000[/tex]

[tex]R=11,200[/tex]

Therefore, maximum revenue is 11200 at price p=10.

Following are the calculation to fill in the blank:

For Part a)

Each home in this town consumed

[tex]\to 40 \times \frac{19000000}{115000000}\\\\\to 40 \times \frac{19}{115}\\\\\to 40 \times 0.165\\\\\to 6.6 \ \text{gallons of oil per day}[/tex]

For Part b)

Without completing the sentence,

[tex]\text{Total consumption = 19200000 barrels}\\\\\text{Total number of households = 118000000}[/tex]

As a result, each household consumed.

[tex]\to \frac{19200000}{118000000} \\\\\to \frac{192}{1180} \ (barrels)\\\\[/tex]

In the given scenario, each barrel includes 42 gallons of oil. Therefore, every household consumed [tex]42 \times \frac{192}{1180} = 6.83 \ gallons[/tex] oil each day.

Hence, each household will consume 6.60 gallons per day.

Total Households of that country =115000000 (approx.)

Total barrels used per day =19000000 (approx.)

Given 1 barrel = 40 gallons (approx.)

So total gallons used per day = 19000000 x 40 =760000000

So each household will consume gallons per day = total gallons used per day / Total household of that country

=[tex]=\frac{760000000}{ 11500000}[/tex]

=6.60 gallons/household/day

So each household will consume 6.60 gallons per day.

Answer:

b

Step-by-step explanation:

Let x represent the number of quarts of Tuscan sauce and

y represents the number of quarts of marinara sauce Tiffany makes.

A quart of Tuscan sauce requires 6 tomatoes and 1 cup of oil

x quarts requires 6x tomatoes and 1x cups of oil

A quart of her marinara sauce requires 5 tomatoes and 1.25 cups of oil

y quarts requires 5y tomatoes and 1.25 y cups of oil

She has 45 tomatoes and 10 cups of oil on hand.

So the constraints are

6x+5y≤45

1x+1.25y≤10

x>=0 and y>=0

After drawing a diagram of what's required to make 1 quart of Tuscan and 1 quart of Marinara sauce, you can more clearly choose answer choice (B) 6x + 5y < (or equal to) 45, x + 5/4y < (or equal to) 10, x>(or equal to)0, y>(or equal to)0.

Answer:

Sports, Class, Bathrooms

Step-by-step explanation:

When playing sports it is near impossible to social distance. Tackling contact, you name it. Sitting in class, sharing desks with the classes that come before. Especially that student that hides gum under the table. Everyone shares bathrooms. It can't be cleaned as soon as someone uses it. All of these are reasons for the virus to spread.

Answer:

A large body of students could prove to be very dangerous, given how contagious the virus in question is. Students and teachers make contact with each other constantly, and that will surely infect nearly 70% of the facility's occupants.

Answer:

Option D.

Step-by-step explanation:

It is given that the endpoints of the diameter of a circle are (6, 5) and (−2, 3). So, midpoint of these end point is the center of the circle.

[tex]Center=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Center=\left(\dfrac{6+(-2)}{2},\dfrac{5+3}{2}\right)[/tex]

[tex]Center=\left(\dfrac{4}{2},\dfrac{8}{2}\right)[/tex]

[tex]Center=\left(2,4\right)[/tex]

So, center of the circle is (2,4).

Length of diameter of the circle is the distance between (6, 5) and (−2, 3).

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d=\sqrt{(-2-6)^2+(3-5)^2}[/tex]

[tex]d=\sqrt{(-8)^2+(-2)^2}[/tex]

[tex]d=\sqrt{64+4}[/tex]

[tex]d=\sqrt{68}[/tex]

[tex]d=2\sqrt{17}[/tex]

So, radius of the circle is

[tex]r=\dfrac{d}{2}=\dfrac{2\sqrt{17}}{2}=\sqrt{17}[/tex]

Standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where, (h,k) is center of the circle and r is radius.

Substitute h=2, k=4 and [tex]r=\sqrt{17}[/tex] in the above equation.

[tex](x-2)^2+(y-4)^2=(\sqrt{17})^2[/tex]

[tex](x-2)^2+(y-4)^2=17[/tex]

Therefore, the correct option is D.

Answer:

Option B ,$133.92  is correct

Step-by-step explanation:

By consolidating both balances in Card B,APR of 12% would apply to funds in card A as well

Let us approach the question by solving for monthly payment of  Card A using   12% APR as follows while making use of excel pmt formula:

=pmt(rate,nper,-pv,fv)

rate is the monthly rate on the card which is 12%/12=1%

nper is the number of months of payment which is 12 months * 4 years=48

pv is the current balance in the card which is $1,389.47

fv is the total amount of monthly repayment which is taken as zero

=pmt(1%,48,-1389.47,0)=$ 36.59  

Using 16% monthly payment is $39.38  which is given already

Total monthly payments for 16%=$39.38*48=$1890.24

Total monthly payments for 12% APR=$36.59*48=$1756.32

savings in total repayments=savings in interest=$1890.24 -$1756.32 =$133.92

Answer:

its Combine like terms sorry the answer is kind of late

Step-by-step explanation:

The first step in solving the given equation is Combine the like terms.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given is an equation,

gx + 3x + 2 = 57

Like terms are terms which are having the same variable or they are constants.

Here gx and 3x are like terms since both of then has the variable x.

2 and 57 are constants.

gx + 3x + 2 = 57

Combine the like terms.

(g + 3)x = 57 - 2

(g + 3)x = 55

Hence the first step is combining like terms.

Find the height, h ?

Formula used :

Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )

Solution:

We know that that,

Area of rectangular prism ( cuboid ) = 2 ( lb + bh + hl )

=> 448 = 2 ( 14 × 6 + 6 × h + h × 14 )

=> 448 = 2 ( 84 + 6h + 14h )

=> 448 = 2 ( 84 + 20h )

=> 448 = 168 + 40h

=> 40h = 448 - 168

=> 40h = 280

=> h = 280/40

=> h = 7 cm

Answer:

Option C.

Step-by-step explanation:

Given: In [tex]\Delta OPQ,m\angle O=107^{\circ},m\angle P=28^{\circ} [/tex].

In [tex]\Delta OPQ[/tex],

[tex]m\angle O+m\angle P+m\angle Q=180^{\circ}[/tex]    (Angle sum property)

[tex]107^{\circ}+28^{\circ}+m\angle Q=180^{\circ}[/tex]

[tex]135^{\circ}+m\angle Q=180^{\circ}[/tex]

[tex]m\angle Q=180^{\circ}-135^{\circ}[/tex]

[tex]m\angle Q=45^{\circ}[/tex]

Now,

[tex]m\angle O>m\angle Q>m\angle P[/tex]

In a triangle, the greatest angle has largest opposite side and smallest angle has smallest opposite side. So, we conclude that

[tex]PQ>OP>QO[/tex]

Therefore, the correct option is C.
