A pizza place has pizzas in 2 different sizes, with 8 different flavors for the crust, and 8 different toppings.
How many one-topping pizzas can be ordered?
Use multiplication:
[tex]2\text{ sizes}*8\text{ flavors}*8\text{ toppings}=\large\boxed{128\text{ pizzas}}[/tex]
This question is basically the same as the other question of yours that I answered, so the explanation is very similar:
You can imagine the possibilities as leaves on a tree. Your tree has 2 large branches to represent the two possible sizes. Each of those branch off into 8 smaller branches, each representing a crust flavor. Each one of the smaller branches has 8 leaves to represent a different topping. Each leaf is a combination of a size, a crust flavor, and a topping, so it represents a complete pizza. Your job is to calculate the number of leaves.
Solven/6 =24/36, for the unknown quantity,n.
n=192
n=144
n=108
n=4
Answer:
n = 4
Step-by-step explanation:
[tex]\frac{n}{6} =\frac{24}{36}[/tex]
cross multiply
24*6 = 144
n * 36 = 36n
144 = 36n
divide both sides by 36
n = 4
answer is D
n=4
simplify the fraction on the right to get 4/6
n/6 = 4/6
since denominators are same, you can cancel those
therefore, your answer will be n=4

two siblings are 55 years old combined the youngest sibling is 9 years younger than the oldest sibling how old is the youngest sibling
To solve systems of equations word problems, we can delegate certain variables to subjects mentioned in the word problem. From there, we can form equations based on the given values.
Solving the QuestionLet a be the older sibling's age and b be the younger sibling's age.
We're given:
a + b = 55 years oldb + 9 years = aAll we've done so far is translate the given sentences into equations. Now, we have to solve for b, which is the age of the youngest sibling. Solve using substitution:
[tex]a+b=55\\(b+9)+b=55\\b+9+b=55\\2b+9=55\\2b=46\\b=23[/tex]
Therefore, the younger sibling is 23 years old.
Answer23 years old.

What is the height of a cylinder with a volume of 384 pi cubic inches and a radius of 8 inches? Round to the nearest tenth of an inch.
inches
Answer: 1.9 inches
Step-by-step explanation:
- the equation to find the volume of a cylinder is V = π r^2 h
- so we can just change this equation around to H = V / π r^2
- so H = 384/ π 8^2 = 1.91 or 1.9

Schweser Satellites Inc. produces satellite earth stations that sell for $115,000 each. The firm's fixed costs, F, are $3 million, 50 earth stations are produced and sold each year, profits total $600,000, and the firm's assets (all equity financed) are $4 million. The firm estimates that it can change its production process, adding $3 million to assets and $500,000 to fixed operating costs. This change will reduce variable costs per unit by $12,000 and increase output by 15 units. However, the sales price on all units must be lowered to $110,000 to permit sales of the additional output. The firm has tax loss carryforwards that render its tax rate zero, its cost of equity is 13%, and it uses no debt.

Swap only the right-hand sides of both equations
2) Based on the previous answer, are the systems equivalent? In other words, do they have the same solution?
CORRECT (SELECTED)
No
For the given systems we have:
1) Swap the right sides of both equations in system A.
2) No, the systems are not equivalent systems.
How can we get System B from System A?
The two systems are:
A:
-10x - 4y = 0
-2x + 7y = 8
B:
-10x - 4y = 8
-2x + 7y = 0
Notice that the only different thing between the systems is that the right sides are inverted. So, if we invert the right side of A, we will get system B.
2) Are the systems equivalent?
No, the systems are not equivalent because to go from system A to system B we only modified the right side of system A, the systems would be equivalent only if modifying both sides of A gave system B, but this is not the case.

What is the equation of the quadratic function shown in the graph?
The equation of the quadratic function shown in the graph y - 8 = -2(x + 1)².
How to illustrate the graph?The vertex of this parabola is (-1, 8). It opens downward, so the x² term has a negative coefficient. The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).
Through the vertex form of the equation of a parabola we get:
y - (8) = a(x - (-1)) + 7, or.y - 8 = a(x + 1)².
Find coefficient a by substituting the coordinates (-3, 0) in this equation:
0 - 8 = a(-3 + 1)^2, or
-8 = a(-2)² or a = -2
The desired equation is y - 8 = -2(x + 1)^2

tommy starts walking from school to home at the same time that his dad starts walking home to school the both depart at 300pm tommy is walking at a speed of 1.35meters pr second and his dad is walking at a speed of 1.65 meters per second. the distance between home and school is 720 meters at what time wil they meet
Tommy and his father will meet after 2400 seconds or 40 minutes. So they will meet at 3:40 pm.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.
Given that:-
Tommy starts walking from school to home at the same time that his dad starts walking home to school they both depart at 300pm Tommy is walking at a speed of 1.35meters per second and his dad is walking at a speed of 1.65 meters per second. the distance between home and school is 720 meters at what time will they meetThe time will be calculated by using the relative speed concept.
Relative speed = Speed of father - Speed of Tommy
Relative speed = 1.65 - 1.35
Relative speed = 0.3 meter per second
Relative speed = Distance / Time
0.3 = 720 / Time
Time = 720 / 0.3
Time = 2400 seconds = 2400/ 60 = 40 minutes
We know that both departed at 3 pm they will meet at 3:40 pm.
Therefore Tommy and his father will meet after 2400 seconds or 40 minutes. So they will meet at 3:40 pm.

Answer:
They will meet at 3:04 p.m
Step-by-step explanation:
Since they are walking toward each other, that means we should add their speed together:
speed = 1.35 m/s + 1.65 m/s
= 3 m/s
Now that we have found the speed, we can calculate the time:
time = 720 meters / 3 m/s
= 240 seconds
= 4 minutes ( 240 seconds is 4 minutes)

What is a truth table?A truth table is a mathematical table which shows the truth values for a given set of arguments and tells if the argument is valid or invalid.
Analysis:
Argument 1( P)= if a person is on this reality show(true) T
Argument 2(Q) = the person is self absorbed true(T)
Laura is not self absorbed = False(≈Q)
Laura wont be on the reality show = False(≈P)

$10
$20
$30
$100
Work Shown:
i = P*r*t
i = 200*0.05*2
i = 20
A quick mental shortcut is to double the 5% interest to get 10%, since this occurs over 2 years. Then taking 10% of something is the same as moving the decimal point one spot to the left. So we go from 200 to 20
