Step-by-step explanation:
...............
Answer:
A. 8/15
B. 36/-12 = 3/-1 (-3)
C. -15/-7 (15/7)
D. -30/3 = -10/1 (-10)
Step-by-step explanation:
To find the quotient of two fractions, change the equation from division to multiplication.
Each time you divide fractions, remember this:
SAME, CHANGE, RECIPROCAL (FLIP)
For example, 2/5 ÷ 3/4
SAME: Keep 2/5 as it is.
CHANGE: Change the division to a multiplication sign.
RECIPROCAL (FLIP): Switch the numerator and denominator; 3/4 would become 4/3.
2/5 x 4/3
(Multiply the numerators and denominators).
2/5 x 4/3 = 8/15.
Now, repeat this with other equations.
9/4 ÷ -3/4
9/4 x 4/-3 = 36/-12 = 3/-1 (-3)
-5/7 ÷ -1/3
-5/7 x 3/-1 = -15/-7 = (15/7)
-5/3 ÷ 1/6
-5/3 x 6/1 = -30/3 = -10/1 (-10)
Da solución al siguiente sistema de ecuaciones utilizando el método de igualación. X + y =82 , 5x + 10y = 500 por favor es para hoy.
Answer:
X = 64
Y = 18
Step-by-step explanation:
Para resolver un sistema de ecuaciones de dos incognitas por igualacion:
- Se despeja en ambas sub ecuaciones una incognita y se igualan, para determinar la respuesta del otro valor desconocido
Despejemos la Y en ambas operaciones:
Y = 82 - X
Y = (500 - 5X) 1/10
Y = 50 - 1/2X
Ahora igualamos
82 - x = 50 - 1/2x
82 - 50 = -1/2x + x
32 = 1/2x
x = 32 . 2
x = 64
Volvemos a las dos sub ecuaciones
Y = 82 - 64 → 18
Y = (500 - 5 . 64) / 10
Y = (500 - 320) / 10
Y = 180 / 10 → 18
If a rock weighs 3.24 pounds on Saturn, what will it weigh on Earth?
Answer:
weight on saturn = (weight on earth/9.8) x 10.44
So,
3.24 = (x/9.8) x 10.44
0.3103 = x/9.8
x = 3.0409
The rock would weigh 3.0409 pounds on Earth! :)

If it snows tomorrow, the probability is 05 that John will practice his trombone. If it does not snow tomorrow, there is only a 0.6 chance that John will practice. Suppose the chance of snow tomorrow is 70%. What is the probability that John will practice his trombone?
Answer:
54 percent
Step-by-step explanation:
The final probability is a weighted average of the going to play probabilities determined for each weather scenario:
P(John performs cello; provided that it rains) * P(it rains) + P(it rains) + P(it rains) + P(it rains) + P(it rains) +
If it doesn't rain, P(John plays cello) * P(it doesn't rain) =
0.54 = 0.6 * 0.7 + 0.4 * 0.3
The likelihood is 54 percent.

There are two vendors at the fair sleeping snow cones for the same price. If the containers are completely filled and then leveled off across their tops, what is the difference in the amount of snow cone each will hold
Answer:
[tex]d = 787.81cm^3[/tex]
Step-by-step explanation:
Given
See attachment for the containers
Required
The difference in the amount of snow cone they hold
The amount they hold is determined by calculating the volume of the containers.
The traditional snow cone has the following dimension
Shape: Cone
[tex]r=4cm[/tex] --- radius
[tex]h = 13cm[/tex] --- height
The volume is calculated as:
[tex]Volume = \frac{1}{3} \pi r^2h[/tex]
So, we have:
[tex]V_1 = \frac{1}{3} \pi * 4^2 * 13[/tex]
[tex]V_1 = \frac{208}{3} \pi[/tex]
The snow cone in a cup has the following dimension
Shape: Cylinder
[tex]r=8cm[/tex] --- radius
[tex]h = 5cm[/tex] --- height
The volume is calculated as:
[tex]Volume = \pi r^2h[/tex]
So, we have:
[tex]V_2 = \pi *8^2 * 5[/tex]
[tex]V_2 = \pi *320[/tex]
[tex]V_2 = 320\pi[/tex]
The difference (d) in the amount they hold is:
[tex]d = V_2 - V_1[/tex]
[tex]d = 320\pi - \frac{208\pi}{3}[/tex]
Take LCM
[tex]d = \frac{3*320\pi -208\pi}{3}[/tex]
[tex]d = \frac{960\pi -208\pi}{3}[/tex]
[tex]d = \frac{752\pi}{3}[/tex]
Take [tex]\pi = 22/7[/tex]
[tex]d = \frac{752}{3} * \frac{22}{7}[/tex]
[tex]d = \frac{752 * 22}{3*7}[/tex]
[tex]d = \frac{16544}{21}[/tex]
[tex]d = 787.81cm^3[/tex]

⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️If the area of a circle is 113.04 sq ft, what is the diameter of that circle?
Answer:
12ft
Step-by-step explanation:
A=π r^2
113.04 = π r^2
113.04/ π = π r^2/ π
35.98=r^2
√35.98 =√r^2
r= 5.998
d=r*2
d=5.998*2
d=11.9969 rounded to 12 i guess

I bought a 5lb bag of sugar. I used 1 2/3 for cookies and 2 3/4 for cake. How much sugar do I have left?
Answer:
7/12lb
Step-by-step explanation:
5-1 2/3-2 3/4
=5-5/3-11/4
=10/3-11/4
=40/12-33/12
=7/12lb
Answer:
[tex]\frac{7}{12}[/tex]
Step-by-step explanation:
There was an initial amount of 5 lbs.
[tex]1\frac{2}{3}+2\frac{3}{4}=4\frac{5}{12}[/tex]
4 (5/12) of the sugar was used.
[tex]5 - 4\frac{5}{12}=\boxed{\frac{7}{12}}[/tex]
(7/12) of sugar should be remaining.

Carl ordered a refrigerator that weighs 192 pounds. It was shipped to him inside a box and
surrounded by packaging material. The total weight of the refrigerator, box, and packaging
material was 205 pounds.
What is the weight of the box and packaging material?
Enter your answer in the box.
pounds
Answer:
13 pounds
Step-by-step explanation:
We know that the total weight of everything is 205 pounds, and the fridge itself is 192 pounds. So we need to calculate the weight of everything that is not a fridge, which would be:
205 - 192 = 13 pounds
That means that the box and the packaging is 13 pounds. Hope this helps!
