One pump can fill a tank of water in 2 hours. A second tank can fill the same tank in 3 hours. If both pumps are used together, how long will it take to fill the tank? 5/6 hours 6/5 hours 3/2 hours 2/3 hours
Answer:
6/5 hours
Step-by-step explanation:
GIVEN :-
Lets say ,
Pump A takes 2 hours to fill the tank alonePump B takes 3 hours to fill the tank aloneTO FIND :-
Time taken by both pumps to fill the tank when used togetherPROCEDURE :-
In 2 hours , Pump A fills the whole tank.
⇒ In 1 hour , Pump A will fill 1/2 part of tank. (By using Unitary method)
In 3 hours , Pump B fills the whole tank.
⇒ In 1 hour , Pump B will fill 1/3 part of tank. (By using Unitary method)
In 1 hour , when both pumps will be used together , they will fill =
(Part of tank filled by A in 1hr) + (Part of tank filled by B in 1hr)
⇒ [tex]\frac{1}{2} + \frac{1}{3}[/tex]
[tex]=> \frac{5}{6}[/tex] part of tank
5/6 part of tank will be filled by both the pumps in = 1 hour.
Using unitary method, multiplying both the sides with 6/5 -
⇒ 5/6 × 6/5 part of tank will be filled by both the pumps in = 1 × 6/5 hours
⇒ Total tank (or 1 whole tank) will be filled by both the pumps in = 6/5 hours
∴ Both the pumps will take 6/5 hour to fill the tank , when used together.

Answer:
d= 90 degrees
e= 66 degrees
f= 114
Step-by-step explanation:
D is 90 because the measure of the angle on the line is 180 and it shows that the other angle is 90 and 180- 90= 90. E is 66 because opposite angles are congruent. F is 114 because they lie on a straight line which has the measure of 180 and 180- 66= 114
Answer:
d = 90°
e = 66°
f = 114°
Step-by-step explanation:
d = 90°
e = 66°
Reason : Vertically opposite angles
Angles f and 66° are in the linear pair.
f + 66° = 180°
f = ( 180 - 66 )°
f = 114°

Use a formula to find the amount of wrapping paper you need to wrap a gift in the
cylindrical box shown. You need to cover the top, bottom, and all the way around
the box. Use 3.14 for it.
7 in. height to 9 in. radius
Answer:
100.48 square inches
Step-by-step explanation:
Surface area of a cylinder = 2πr(r+h)
r is the radius
h is the height
Given
radius = 9in
height = 7in
π = 3.14
Substitute into the formula
Surface area of the cylinder = 2(3.14)(9+7)
Surface area of a cylinder = 2*3.14*16
Surface area of a cylinder = 100.48 square inches
Hence the amount of wrapping paper you need to wrap a gift in the
cylindrical box is 100.48 square inches
Gia knows that the formula for the surface area of a cube is A = 6s2, where s is the cube's side length. She wants to find the surface area of a cube with sides of length of LaTeX: \frac{1}{4}1 4- foot. What is the surface area of this cube?
Answer:
The area of the cube is equal to [tex]0.375\ \text{foot}^2[/tex].
Step-by-step explanation:
The formula for the surface area of a cube is :
[tex]A=6s^2[/tex]
Where
s is the cube's side length
Put s = 1/4 foot
So,
[tex]A=6\times (\dfrac{1}{4})^2\\A=0.375\ \text{foot}^2[/tex]
So, the area of the cube is equal to [tex]0.375\ \text{foot}^2[/tex].
C. If Stephanie was short of wrapping paper, how much more did she need? If Stephanie had enough wrapping paper, how much of the ten feet was left over?
Complete question :
Stephanie has six identical gift boxes to wrap. Each box is a cube that measures 6 inches on each side. She would like to wrap them all using the same gift wrapping paper. The roll of wrapping paper she has is 30 inches wide and 10 feet long.
Answer:
Left over = 2292 in²
Step-by-step explanation:
Given that :
Gift boxes are identical ;
Each gift box is a cube with side length, s = 6 inches
Area of gift box, Surface area of a cube = 6s²
Area = 6(6²) = 6 * 36 = 216 in²
Area of one gift box = 216 in²
6 gift boxes will be : 216 in² * 6 = 1296 in²
Allowing 2 inches to cover for overlap in each box : 2 inches * 6 = 12 in²
Dimension of wrapping paper = 30 inches by 10 feets
Recall :
1 Feet = 12 inches
Hence ; dimension of wrapping paper becomes :
30 inches by (10*12) inches
30 inches by 120 inches
Area of wrapping paper = 30 * 120 = 3600 in²
Total area of paper - area of gifbox - area of overlap
(3600 - 1296 - 12) in²
= 2292 in²
Leftover = 2292 in²

A cylindrical tank with a radius of 12 inches and a height of 20 inches is full of water. does the tank have enough water to fill 250 spherical shaped water balloons if each of the water balloons has a radius of 2 inches? Explain plz
Answer:
yes It has
Step-by-step explanation:
v of the tank
v= [tex]\pi[/tex]r^2 h
v=3.14*144*20
v=9034
the v of each ballon :
V = 4/3 [tex]\pi[/tex]r^3
v=4/3 * 3.14 .8
v= 33.5
all the ballons v is 250 * 33.5 = 8373
9034-8373 = 661 v of the water in the tank would be left

9. Hallar el perímetro de la figura sombreada.
Lado del cuadrado 6 m. (Las curvas son
semicircunferencias)
M
Respuesta:
Perímetro de la parte sombreada = (6pi + 24)
Explicación paso a paso:
Encuentra el diagrama adjunto
Primero necesitamos encontrar el perímetro de los semicírculos externos que sobresalen
Diámetro del semicírculo = 1/2 de la longitud del lado del cuadrado
Diámetro del semicírculo = 1/2 × 6 m = 3 m
Perímetro de los 4 semicírculos = 4 (pi d)
Perímetro de los 4 semicírculos = 4 × 3,14 × 3
Perímetro de los 4 semicírculos exteriores = 1
2pi cm
Para la parte interior sombreada = Perímetro de todo el cuadrado - Perímetro de semicírculo (2 cuadrantes)
Perímetro del cuadrado entero = 4 (6) = 24m
Perímetro de los 2 cuadrantes = pi d
Perímetro de los 2 cuadrantes = 6pi cm
Para la parte sombreada interior, perímetro = 24-6pi
Perímetro de la parte sombreada = 12pi + 24-6pi
Perímetro de la parte sombreada = (6pi + 24) cm

In conditional probability, the notation P(
AB) is read:
"The probability of event A occurring given that event B has
occurred."
For example: In the following two-way table

P(Take the bus | Sophomore ) = [?]
Round to the nearest hundredth.
The value of the probability represented by P(Take the bus | Sophomore) is 0.83
What are conditional probabilities?Conditional probabilities are probabilities that only occurred because an event has already occurred i.e. they are dependent on the initial event
How to determine the conditional probabilities?From the table of values in the question, we have the following parameters:
Number of students that (Take the bus and Sophomore) = 25Number of students that are (Sophomore) = 2 + 25 + 3The required probability represented by P(Take the bus | Sophomore ) = [?] is then calculated as:
P(Take the bus | Sophomore) = Number of students that (Take the bus and Sophomore) divided by Number of students that are (Sophomore)
Substitute the known values in the above equation
P(Take the bus | Sophomore) = 25/(2 + 25 + 3)
Evaluate the sum in the denominator
P(Take the bus | Sophomore) = 25/30
Evaluate the above quotient
P(Take the bus | Sophomore) = 0.83
Hence, the value of the probability represented by P(Take the bus | Sophomore) is 0.83
