7/12 divided by 3 3/4
Answer:
The answer is 7/45
Step-by-step explanation:
First you make 3 3 /4 into an improper fraction which becomes 15/4
Next, you do KFC which is keeping 7/12, making the division sign into multiplication, and then finally you flip 15/4 to 4/15.
Your final answer is 7/45

Answer:
C.
Step-by-step explanation:
Answer: C
Step-by-step explanation:
Say we had 2 fractions:
2/4 & 3/6
and we were trying to find out if they were proportional.
An easy way to do this is to divide the numerator of the second fraction by the numerator of the first fraction, then multiply what you get by the denominator of the first fraction. If your final number equals the denominator of the second fraction, then the two fractions are proportional.
Let me demonstrate:
2/4 and 3/6
1. 3 ÷ 2 = 1.5
2. 1.5 × 4 = 6
3. 6 = 6
Therefore, these fractions are proportional.
Let's try another problem:
4/5 and 10/19
1. 10 ÷ 4 = 2.5
2. 2.5 × 5 = 12.5
3. 12.5 ≠ 19
Therefore, these fractions are not proportional.
Hope this helps!
Román preguntó en servicio al cliente si le podían fabricar los Zetas con medidas especiales aló cual respondieron que si él requiere una loseta cuadrada con un aria de 225 m² cuanto miden los lados de la loseta que le fabricaron
Answer:
Los lados de la lista cuadrada que le fabricaron miden 15 m
Step-by-step explanation:
Hola! Sabemos que la loseta tiene área cuadrada y que el área del cuadrado está dada por:
Ac = a²
Donde a es la medida de los lados del cuadrado.
Para hallar la medida de la lista cuadrada despejamos a aplicando raíz cuadrada a ambos miembros:
a = √(Ac)
a = √(225 m²)
a = 15 m
Los lados de la lista cuadrada que le fabricaron miden 15 m
Respuesta: Los lados de la lista cuadrada que le fabricaron miden 15 m

Answer:
57kg
Step-by-step explanation:
We need to find the length of each piece of metal:
We already know that 2 of them are 6m and 8m and this would be the same for the pieces of metal opposite.
So we have four lengths - 6m, 6m, 8m, and 8m
To find the last length, we need to use pythagoras theory
a² + b² = c² where c is the slanted side, or the diagonal
6² + 8² = c²
36 + 64 = 100
c² = 100
c = √100 = 10
So the five lengths are 6m, 6m, 8m, 8m, and 10m and the total is 38m
If:
1m = 1.5kg
38m = ?kg
We have to multiply both sides by 38
1m × 38 = 38m
1.5kg × 38 = 57kg
So, the total weight of metal in the frame is 57kg
7y+3=3x+11
find x and y
Answer:
7y + 3 = 3x + 11
7y = 3x + 11 - 3
7y = 3x + 8
y = 3x + 8 / 7
7y + 3 = 3x + 11
7y + 3 - 11 = 3x
7y - 8 = 3x
x = 7y - 8 / 3

Nick has two pet rabbits. He's Flemish giant rabbit weighs 5 times as much as his Holland lop rabbit.
If Nick's Flemish giant rabbit weighs 11 more pounds than he's Holland lop rabbit, how much does his Flemish giant rabbit weigh?
Taking into account the definition of a system of linear equations, the weigh of Flemish giant rabbit is 13.75 pounds.
System of linear equationsA system of linear equations is a set of two or more first degree equations, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, a solution to a system of two or more linear equations is a solution that simultaneously satisfies all the equations in the system
Flemish giant rabbit weighIn this case, a system of linear equations must be proposed taking into account that:
"f" is the Flemish giant rabbit weigh."h" is the Holland lop rabbit weigh.You know:
Flemish giant rabbit weighs 5 times as much as his Holland lop rabbit.Nick's Flemish giant rabbit weighs 11 more pounds than he's Holland lop rabbit.The system of equations to be solved is
f= 5×h
f= h +11
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, substituting the first equation in the second you get:
5×h= h + 11
Solving:
5×h- h= 11
4×h= 11
h= 11÷ 4
h= 2.75
Substituting this value in the first equation of the system of equations:
f= 5×2.75
f= 13.75
Finally, Flemish giant rabbit weighs 13.75 pounds.

a model of a ship is made to a scale of 1:200
the surface area of the model is 7500 cm²
calculate the surface area of the ship, giving your answer in square meters
The surface area of the ship is 1500000 cm²
Scaling is used to either increase or decrease the size of a figure so as to create an image.
Given a scale of 1:200, this means that it is a scaling down (decrease in size) of the ship to create a model.
The surface area of the model is 7500 cm², hence that of the ship is:
Surface area of ship * (1 : 200) = surface area of model
Surface area of ship = surface area of model * 200 = 7500 * 200 = 1500000 cm²
The surface area of the ship is 1500000 cm²

Identify the 16th term of a geometric sequence where a1 = 4 and a8 = −8,748.
Step-by-step explanation:
The formula used to determine the terms is
an = a1 × rn - 1
It is given that
a1 = 4
a8 = -8,748
Substituting the values in the formula
-8748 = 4 × r8 - 1
r7 = -8748/4
r7 = -2187
r = -3
So the 16th term is
a16 = 4 × 316-1
a16 = -57395628
Therefore, the 16th term is -57395628.
Find the radius of a cube whose volume is 994 cubic centimeters.
Using work to find the radius
Answer:
Side of the cube: 10cm
Step-by-step explanation:
Firstly, I'd like to state that cubes actually do not have a radius, they have sides. Hence, I am going to solve for sides below:
Volume formula for a cube:
v = s³
Since the volume is 994 cm³
s³ = 994
s = [tex]\sqrt[3]{994}[/tex]
= 9.97995986613
≈ 10cm

what is n if k is 99
Answer:
1/4 or 0.25Step-by-step explanation:
k= 100- 4n
what is n if k is 99
-------
99 = 100 - 4n
4n = 100 - 99
4n = 1
n = 1/4 or 0.25
--------------check
99 = 100 - 4 × 1/4
99 = 100 - 1
99 = 99
the answer is good
