7/8 cups of sauce are needed to make 1 pizza.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Domino's can make 4 pizzas using 3 1/2 cups of sauce.
Now, for 1 pizza he needed
= (3 1/2) /4
= (7/2)/ 4
= 7/2 x 1/4
= 7/8 cups of sauce.
Hence, 7/8 cups of sauce needed.

Step-by-step explanation:
A conical water tank with vertex down has a radius of 13 feet at the top and is 21 feet high. If water flows into the tank at a rate of 30 ft^3/min, how fast is the depth of the water increases when the water is 17 feet deep?
The depth of the water is increasing at equation editorEquation Editor_____ ft/min.
Answer:
[tex]\frac{dh}{dt}\approx0.08622\text{ ft/min}[/tex]
Step-by-step explanation:
We know that the conical water tank has a radius of 13 feet and is 21 feet high.
We also know that water is flowing into the tank at a rate of 30ft³/min. In other words, our derivative of the volume with respect to time t is:
[tex]\frac{dV}{dt}=\frac{30\text{ ft}^3}{\text{min}}[/tex]
We want to find how fast the depth of the water is increasing when the water is 17 feet deep. So, we want to find dh/dt.
First, remember that the volume for a cone is given by the formula:
[tex]V=\frac{1}{3}\pi r^2h[/tex]
We want to find dh/dt. So, let's take the derivative of both sides with respect to the time t. However, first, let's put the equation in terms of h.
We can see that we have two similar triangles. So, we can write the following proportion:
[tex]\frac{r}{h}=\frac{13}{21}[/tex]
Multiply both sides by h:
[tex]r=\frac{13}{21}h[/tex]
So, let's substitute this in r:
[tex]V=\frac{1}{3}\pi (\frac{13}{21}h)^2h[/tex]
Square:
[tex]V=\frac{1}{3}\pi (\frac{169}{441}h^2)h[/tex]
Simplify:
[tex]V=\frac{169}{1323}\pi h^3[/tex]
Now, let's take the derivative of both sides with respect to t:
[tex]\frac{d}{dt}[V]=\frac{d}{dt}[\frac{169}{1323}\pi h^3}][/tex]
Simplify:
[tex]\frac{dV}{dt}=\frac{169}{1323}\pi \frac{d}{dt}[h^3}][/tex]
Differentiate implicitly. This yields:
[tex]\frac{dV}{dt}=\frac{169}{1323}\pi (3h^2)\frac{dh}{dt}[/tex]
We want to find dh/dt when the water is 17 feet deep. So, let's substitute 17 for h. Also, let's substitute 30 for dV/dt. This yields:
[tex]30=\frac{169}{1323}\pi (3(17)^2)\frac{dh}{dt}[/tex]
Evaluate:
[tex]30=\frac{146523}{1323}\pi( \frac{dh}{dt})[/tex]
Multiply both sides by 1323:
[tex]39690=146523\pi\frac{dh}{dt}[/tex]
Solve for dh/dt:
[tex]\frac{dh}{dt}=\frac{39690}{146523}\pi[/tex]
Use a calculator. So:
[tex]\frac{dh}{dt}\approx0.08622\text{ ft/min}[/tex]

John throws a ball upward at a rate of 22 meters per second from an
initial height of 3 meters. The height of the ball above the ground can
be approximated by h (t) = -16t2 + 22.0 + 3, where t represents
the amount of time, in seconds, since the ball has been released.
How many seconds will it reach the ground?
Answer:
1.5 seconds
Step-by-step explanation:
The height equation is supposed to be ...
h(t) = -16t^2 +22t +3
We want to find the positive value of t where h(t) = 0.
0 = -16t^2 +24t -2t +3 . . . . facilitate factoring
0 = -8t(2t -3) -1(2t -3) . . . . . factor by pairs
0 = -(8t +1)(2t -3) . . . . . . . . complete the factoring
The solutions to this are ...
t = -1/8, 3/2
The ball will reach the ground in 1.5 seconds.

A car travels 32 km due north and then 46 km in a direction 40 degrees west of north. Find the magnitude of the cars resultant vector nearest tenth
Answer:
Step-by-step explanation:
In order to find the magnitude of the car's final displacement (resultant displacement vector), we need the x and y components of each part of the car's journey. We will call them vector A and vector B. The info for the vectors is as follows:
A: magnitude 32 at an angle of 90.0
B: magnitude 46 at an angle of 40.0
The x components are found in the formula
A(x) = magA*cos(angle)
For A(x):
A(x) : 32cos(90.0) = 0.0 and
For B(x) : 46cos(40.0) = 35.2
For A(y): 32sin(90.0) = 32 and
For B(y): 46sin(40.0) = 3.0 × 10¹
To get the x components of the final vector, add the x components of A and B together:
C(x) : 0.0
35.2
35.2
To get the y components of the final vector, add the y components of A and B together:
C(y) : 32
30
62
Now to get the magnitude, throw it into the magnitude formula, which is identical to Pythagorean's theorem:
C(mag) = [tex]\sqrt{(35.2^2)+(62^2)}=71.3 km[/tex]

Mrs.McEnroe 6th grade class has 15 students 9 of which are boys. How would you describe this ratio
Answer:
3 : 2
Step-by-step explanation:
Number of students in the class = 15
Number of boys in class = 9
To describe ratio;
We know that the number girls in the class will be
15 - 9 = 6 students.
Simply in this class, the ratio of boys to girls:
9 : 6 = 3 : 2
In the class, we have 3 boys to 2 girls.

The sum of 3 consecutive even integers is 36. What is the first of the 3
integers? HURRY I NeED HELP I’ll give brainliest
Given that the sum of 3 consecutive even integers is 36, we can define the variables to be:
N, (N + 2), (N + 4)And we can set up the equation as:
[tex]\sf {N + (N + 2) + (N + 4) = 36} \\ \sf{\longrightarrow 3N + 6 = 36} \\ \sf{\longrightarrow 3N = 30} \\ \sf{\longrightarrow N = 10}[/tex]
The first even number which we assumed was N, which is equal to 10.
And hence the answer will be
[tex]\leadsto \underline{\boxed{\sf{\pink{\quad10\quad}}}}[/tex]
Verification:
3 consecutive even no.s :
N = 10N + 2 = 12N + 4 = 14Their sum = 10 + 12 + 14 = 36
Hence, N = 10 is the solution of the question.

Answer:
#2 and #4
Step-by-step explanation:
area is length times width, so to find your answer you must multiply all the lengths and widths given in the table. when you multiply 3x+6 and 4 (for #2) and simplify, you get 12x+24. when you multiply 2x+4 and 6 (for #4) and simplify, you get the same thing: 12x+24.

solve for x
(x/r)+(x/w)+(x/t)= 1
x/r + x/w + x/t = 1
x (1/r + 1/w + 1/t) = 1
x = 1 / (1/r + 1/w + 1/t)
To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, rwt :
x = 1 / (1/r + 1/w + 1/t) • rwt / rwt
x = rwt / (rwt/r + rwt/w + rwt/t)
x = rwt / (wt + rt + rw)

Determine the equation of the line that passes through the points:
(2, 4) and (6, -4)
Fill the the blanks: y = _x + _
Answer:
y = -2x+8
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/(6-2)
= -8/4
= -2
The slope is -2
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point ( 2,4)
4 = -2(2) +b
4 = -4+b
Add 4 to each side
4+4 = -4+4+b
8 = b
y = -2x+8
