De un depósito se gasta primero la mitad del agua, y luego la cuarta parte de lo que quedaba. Al final,
quedan 12 litros. Hallar la capacidad del depósito.
Answer:5/8 fraction of the deposit has been spent, which is 20 liters
Let "a" be the initial amount of water, then first half the water is used: then a / 2 of water is used and the other half is left at / 2 * (1/4), then the fourth part is used: then 1/8 * a is used, so now it remains: a / 2 - a / 8 = 3/8 * a, so 5/8 * a has been used, then what remains are 12 liters:
3/8 * a = 12 L
a = 12 L * 8/3 = 32 L
Wasted: 32 L - 12 L = 20 L

The wheel on a car completes
25 revolutions and travels about
35.325 meters. Rounded to the
nearest centimeter, what is the
diameter of the wheel? Use 3.14 for pi.
Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m

what is the median of this data set?
16,21,28,30,34,45,58,60
Answer:
32
Step-by-step explanation:
the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.
this is what it would look like.
16, 21, 28, 30, 34, 45, 58, 60
(basically how it is in the problem lol)
since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30 and 34.
you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)
(30+34)/2
we divide by two because there are two numbers.
(30+34)/2
(64)/2

What are the approximate values of the missing side lengths in the triangle below?
120 m
404
BC 136m, AB 89m
BC 89m. AB 136m
BC 105m, AB 162m
BC 162m, AB 106m
Answer:
BC 136m, AB 89m
Step-by-step explanation:
Find the diagram attached
According to sin rule;
a/sinA = b/sinB = c/sinC
From the diagram;
b = 120m
<B = 60degrees
<C = 40degrees
From the sine formula
b/sinB = c/sinC
120/sin60 = c/sin40
csin60 = 120sin40
c = 120sin40/sin60
c = 120(0.6428)/0.8660
c = 77.1345/0.8660
c = 89.06
c = AB = 89m
Get BC;
According to the sine rule
a/sinA = b/sinB
a/sin(180-100) = 120/sin60
a/sin80 = 120/sin60
asin60 = 120sin80
a = 120sin80/sin60
a = 120(0.9848)/0.8660
a = 118.177/0.8550
a = 136.46
Hence a = BC = 136m

If y varies jointly as x and z and y = 4 when x = 2 and z = 3, what is y when x = -6 and z = 2?
Answer:
Step-by-step explanation:
Y = kxz
Putting values of y x and z in the equation
4 = k(2)(3)
4 = k6
2/3 = k
Now finding y when x = - 6 and z = 2
Y = kxz
= 2/3(-6)(2)
= - 8

What is the total area of each garden bed has a length of 4 feet Amelia
Answer:
48 ft^2.
Step-by-step explanation:
In this case, our formula is known as 3s^2 which can be written out as 3 x s x s or 3(s x s). S is the variable to represent our length and width because the formula for finding the area is l x w which can be written out as length x width. If the total area of each garden bed has a length of 4 feet, our equation would be 3(4 x 4) or 3 x 4 x 4 or 3(4)^2. 4 x 4 or 4^2 is 16. If we multiply 16 by 3, the answer would be 48. That is why the total area of each garden bed would be 48 ft^2.

Pepe compró una caja de chocolates en $5.950, incluido el 19% de IVA. ¿Cuál es el precio de la caja de chocolates sin el IVA?
Answer:
$4819.5
Step-by-step explanation:
Pepe bought a box of chocolates for $ 5,950, including 19% VAT. What is the price of the box of chocolates without VAT?
The price of chocolates = $5,950
VAT = 19%
We need to find the price of the box of chocolates without VAT.
VAT is applied on the Cost price of the object.
Price = $5,950 - 19% of $5,950
[tex]=5950- 5950\times \dfrac{19}{100}\\\\=\$4819.5[/tex]
So, the price of the box without VAT is equal to $4819.5.

christen has to run around the rectangle soccer field during practice. The soccer field measures 60 meters long by 45 meters wide. How far did christen run?
Answer:
210 m
Step-by-step explanation:
Perimeter is the distance around the outside of a two-dimensional shape.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
Christen ran around the soccer field, so she ran around the perimeter.
We can find the perimeter by adding all of the side lengths.
Perimeter=60 m+45 m+60 m+45 m
Christen ran 210m.
