Tiffany cells 2 kinds of homemade tomato sauce
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.

A few years ago, a country consumed 19,400,000 barrels of oil per day. That same year, there were about 119,000,000 households in that country. A barrel of oil is 42 U.S. gallons. Estimate how many gallons each household in the country consumed each day that year by rounding down all three numbers. (Round 19,400,000 barrels to 19,000,000 barrels, 119,000,000 households to 115,000,000 households, and 42 gallons to 40 gallons. Round your answer to two decimal places.)
_________ gal/household/day
Calculate the answer without using estimation and compare the two results. (Round your answer to two decimal places.)
___________gal/household/day
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.

brainly.com/question/14798687
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:
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

Combine like terms.
Multiply each side of the equation by 5.
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.
What is an Equation?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

25) The endpoints of the diameter of a circle are (6, 5) and (−2, 3). Which equation represents the circle? A) (x − 2)2 + (y − 4)2 = 9 B) ( x+ 2)2 + (y + 4)2 = 16 C) (x − 2)2 − (y + 4)2 = 16 D) (x − 2)2 + (y − 4)2 = 17
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.

Explain what other reasons might slow or speed up the spread of the virus in any school.
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.
A rectangular prism has a surface area of 448 cm2. It’s length is 14 cm and it’s width is 6 cm. Find the height.
Given:
Length, l = 14 cmBreadth, b = 6 cmArea of rectangular prism ( cuboid ) = 448 cm²To find out:
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

A model for a company's revenue is R = -12p2 + 240p + 10,000, where "p" is the price
in dollars of the company's product. Find the maximum revenue.
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.
A car averages 27 miles per gallon. If gas costs $4.04 per gallon, which of the following is closest to how much the gas would cost for this car to travel 2,727 typical miles? Individual Question $44.44 $109.08 $118.80 $408.04 $444.40
Answer: $408 04
Step-by-step explanation:
Average of the car = 27 miles per gallon
Petrol required to travel 2727 miles = 2727 / 27 = 101 gallons
Cost of petrol = 101 x 4.04 = 408.04
Marcia has two credit cards and would like to consolidate the two balances into one balance on the card with the lower interest rate. The table below shows the information about the two credit cards Marcia currently uses.

12%
Monthly Payment

$28.05
After 4 years, approximately how much will Marcia have saved in interest by consolidating the two balances?
a.
$1,890.24
b.
$133.92
c.
$543.84
d.
$1,346.40
ANSWER IS B
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

B. $133.92
