Answer:
13 hours and 23 minutesStep-by-step explanation:
We know that:
⇒ When it is noon, the time is 12:00 pm⇒ When it is midnight, the time is 12:00 amTherefore,
The provided time is 1 hour 23 minutes ahead than 12:00 am. It will also take 12 hours for midnight from noon.Thus, we obtained:
⇒ Passed time: 12 hours + 1 hour + 23 minutes⇒ Passed time: 13 hours + 23 minutes⇒ Passed time: 13 hours and 23 minutes
A local dairy has three machines to fill half-gallon milk
cartons. The machines can fill the daily quota in 5
hours, 6 hours, and 7.5 hours, respectively. Find how
long it takes to fill the daily quota if all three machines
are running.
Answer:
Step-by-step explanation:
let's assume the quota is 1
1=the time each machine takes to fill the quota thus;
1=5hrs what about 1hr=1/5
1=6hrs what about 1hr =1/6
1=7.5hr what about 1hr =2/15
add: 1/5+1/6+2/15=1/2 reciprocate
=2hrs
Find the missing length pleaseeee!!!
Step-by-step explanation:

What’s 56,105 minus 15 percent
Answer:
833
Step-by-step explanation:
First find the 15% of 56,105;
[tex]\frac{15}{100}[/tex] * 56,105 = x
0.15 * 56,105 = x
882 = x
Now subtract 15% of 56,105 from 56,105;
15% of 56,105 = 882
now;
56,105 - 882 = 833

Milk Glass A has a diameter of 3.5 inches and a height of 4 inches . Glass B has a radious of 1.5 inches and a height of 5 inches. Which glass can hold more milk
Answer:
Milk Glass A can hold more milk.
Step-by-step explanation:
This problem mostly relies on the diameter of the milk glass.
To solve the problem, we'll find the volume of each glass as though it were a cylinder.
First, we start with the area of the base of each cylinder.
Using the formula [tex]\pi r^{2}[/tex], we can find the area of each base.
Note that r represents radius, which is half of the diameter, d.
The area of the base on Milk Glass A can be found with: [tex]\pi 1.75^2[/tex] which equals 9.62 inches squared.
The area of the base on Milk Glass B can be found with: [tex]\pi 0.75^2[/tex] which equals 1.77 inches squared.
Now that we have the area of each base, we just multiple the area by the height to get the full volume.
The volume of Milk Glass A can be found by multiplying [tex]9.62*4[/tex] which equals 38.48 cubic inches.
The volume of Milk Glass B can be found by multiplying [tex]1.77 *5[/tex] which equals 8.85 cubic inches.
Therefore, the larger answer of 38.48 cubic inches means Milk Glass A can hold more milk.

A force of 61 N is applied to an area of 750 cm2.
Calculate the pressure in N/m2.
Give your answer to the nearest integer.
Step-by-step explanation:
Area750 cm² = 750 × 10^-4 m²
pressure = F/A
= 61 /(750×10^-4)
= 61 × 10⁴/750
= 0.081 × 10⁴
= 810 N/ m²
Answer:
813N/m^2
Step-by-step explanation:
Pressure is defined as the amount of force applied to an area. There are 100cm in a single meter, therefore:
[tex]750cm^2=\sqrt{750} cm\frac{1}{100} \frac{m}{cm} =\frac{\sqrt{750} }{100} m=0.075m^2[/tex]
Pressure formula is:
[tex]P=Force/Area=61N/0.075m^2=813N/m^2[/tex]
a cylindrical water bottle is 15 centimeters tall. it can hold 753.6 of water. What is the radius of water the waterbottle? use 3.14 for
Answer:
The answer is 4cm.
Step-by-step explanation:
Given:
Height= 15cm
The volume of the Cylindrical bottle= 753.6
They have said to use π= 3.14
We are supposed to find r.
-------------------------------------------------------------
Volume of cylinder= πr²h
now substitute teh values given in the formula..we will get:
753.6 = 3.14× r²× 15
After u solve it , you will get
r²= 16
∴r = √16= 4cm
So, the radius of the bottle is 4cm

A scale drawing of Jack's living room is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 6 cm, and the width is labeled as width equal to 4 cm. If each 1 cm on the scale drawing equals 5 feet, what are the actual dimensions of the room? (5 points) Length = 11 feet, width = 9 feet Length = 30 feet, width = 20 feet Length = 8 feet, width = 12 feet Length = 22 feet, width = 20 feet
Answer:
(b) Length = 30 feet, width = 20 feet
Step-by-step explanation:
The scale factor is applied to the drawing dimensions to find the actual dimensions.
__
length = (6 cm) × (5 ft)/(1 cm) = 30 ft
width = (4 cm) × (5 ft)/(1 cm) = 20 ft
_____
Additional comment
You can also write the scale factor as part of a proportion:
5 ft : 1 cm :: x ft : 6 cm
Multiplying by 6 cm gives
(5 ft)(6 cm)/(1 cm) = x ft = 30 ft . . . . as above

Option A, [tex]385.0\ ft^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the base
[tex]A = l * w[/tex]
[tex]A = 11\ ft * 11\ ft[/tex]
[tex]A = 121\ ft^2[/tex]
Step 2: Determine the area of the triangles

[tex]A = \frac{12\ ft * (11\ ft / 2)}{2}[/tex]
[tex]A = \frac{12\ ft * 5.5\ ft}{2}[/tex]
[tex]A = \frac{66\ ft^2}{2}[/tex]
[tex]A = 33\ ft^2[/tex]
There are two of these triangles per side which means that there are 8 of these triangles in total.

A garden is in the shape of an isosceles right triangle. The length of the hypotenuse is 24 feet. What is the area of the triangle?
Answer:
Area = 144 ft^2
Step-by-step explanation:
Remark
Use the Pythagorean theorem to find the length of the legs. Then multiply them together and divide by 2.
Equations
a^2 + a^2 = c^2
Area = (1/2) * a^2
Givens
c = 24
Solution
Remember that an isosceles triangle has 2 equal sides. Both legs of the triangle are equal to a.
a^2 + a^2 = c^2 Combine
2a^2 = 24^2 Expand
2a^2 = 576 Divide by 2
2a^2/2= 576/2
a^2 = 288 You might just as well leave this. go to area
Area = 1/2 (288)
Answer: Area = 144 ft^2
A semicircular window has a diameter of 10m what is the perimeter of the window use 3. 14 for pi ?
Please help it’s worth 20 points!!!
Answer:
25.7 m
Step-by-step explanation:
Semicircles are half circles that are divided at the diameter.
We want to find the semicircle arc.
To do this, just find the circumference of the circle and then divide by 2.
Circumference formula:
2rπ or Dπ
10π = 31.4
31.4 / 2 = 15.7
Now, we have to find the straight line part of the semicircle. The length of that straight line is the diameter. We already know that the diameter is 10.
Add
15.7+10 = 25.7

What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?
Answer:
0.571428571429 grams per cm³
Step-by-step explanation:
density = mass/volume
Let’s calculate the volume V of the pyramid :
V = (1/3)×base×height
= (1÷3)×(5×7)×9
= 105 cm³
Then
The density = mass/volume
= 60÷105
= 0.571428571429
