The least amount of water 1/4 full
To get from 1/4 to 3/4, you multiply by 3:
[tex]\frac{1}{4} * \frac{3}{1} = \frac{3}{4}[/tex]

Triangle E B C is shown with its exterior angles. Line E C extends through point F. Line C B extends through point A. Line B E extends through point D. Which statements regarding the diagram of ΔEBC are true? Select three options. ∠BEC is an exterior angle. ∠DEC is an exterior angle. ∠ABE and ∠EBC are supplementary angles. ∠BCF and ∠DEC are supplementary angles. ∠BEC is a remote interior angle to exterior ∠BCF.
Answer:
2, 3, 5 are true statements
Step-by-step explanation:
A diagram of the geometry is helpful. Our understanding of your description is shown in the first attachment. The second attachment shows how the various angles relate to each other. An exterior angle and its adjacent interior angle are a linear pair, so are supplementary.
__
1. BEC is an exterior angle -- False, it is an interior angle
2. DEC is an exterior angle -- True
3. ABE and EBC are supplementary -- True, they are a linear pair
4. BCF and DEC are supplementary -- False, they are unrelated exterior angles

I don't really get alot of help but help me on this one Find the volume pls
Answer:
C. 112 cubic inches
Step-by-step explanation:
Two solve this weird-looking house problem, first let's see what it is made of.
Split the area into two volumes.
V = 1/3lwh is the volume for a triangular prism and V = lwh is the volume for a rectangular prism.
Let's now solve for the triangular prism.
The length and width are the same as that of the cube. The cube's length and width is 4 in.
V = 1/3(4)(4)(6) = 32 cubic inches
Now Solve for the cube.
V = lwh = 4(4)(5) = 80 cubic inches
Total Volume = 80 + 32 = 112 cubic inches
There are 9 students in a service club. The club is making gift baskets for children in a hospital. Each club member donated 4 children’s books for the baskets. Each club member also donated an equal number of toys. A total of 63 items were collected for the baskets. Which linear equation can you use to find how many toys each club member donated?
Answer:
9x + 36 = 63
Step-by-step explanation:
Let x represent the number of toys that each club member donated.
There are 9 students in a service club.
If each club member donated 4 children's books for the baskets, it means that the total number of books donated by the club members would be
9 × 4 = 36
If each club member also donated an equal number of toys. It means that the total number of toys donated by the club members would be
9 × x = 9x
A total of 63 items were collected for the baskets. Therefore, the linear equation that you can use to find how many toys each club member donated would be
9x + 36 = 63

The intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. Suppose intensity is 8000 units at a distance of 2 miles. What will the intensity be at a distance of 12 miles? Round your answer to the nearest unit. A. 205 units b. 222 units c. 248 units d. 186 units.
The intensity of soundwave at a distance of 12 miles is 222.22 miles.
What is Directly proportional and inversely proportional?
The link between two variables whose ratio is equal to a constant number is known as a direct proportional, while the multiplication of two variables whose ratio is equal to a constant number is known as an inversely proportional.
It is given that the intensity of a radio signal from the radio station varies inversely as the square of the distance from the station. therefore, the relation between the intensity of the radio wave(I) and distance(r) can be written as,
[tex]I\propto \dfrac{1}{r^2}\\\\\\I=k \dfrac{1}{r^2}[/tex]
Now, it is stated that the intensity of the radio wave at a distance of 2 miles is 8000 units, therefore, substituting the value in the above equation to get the value of the constant,
[tex]I=k\dfrac{1}{r^2}\\\\8000=k\dfrac{1}{2^2}\\\\8000=k\dfrac{1}{4}\\\\k = 8000 \times 4 = 32,000\rm\ units[/tex]
Thus, the value of the constant k is 32,000 units, and the equation of the intensity of the radio signal can be written as,
[tex]I=\dfrac{32,000 }{r^2}[/tex]
Further, the intensity of soundwave at a distance of 12 miles will be equal to,
[tex]I=\dfrac{32,000 }{r^2}\\\\I=\dfrac{32,000 }{12^2}\\\\I=\dfrac{32,000 }{144}\\\\I = 222.22\rm\ units[/tex]
Hence, the intensity of soundwave at a distance of 12 miles is 222.22 miles.

the sum of ages of Jamal and his father is 40 years.After 4 years,the age of the father will be triple the age of his son.Find the age of Kamal and his father
Answer:
The age of Jamal is 8 years.
And the age of his father is 32 years.
Step-by-step explanation:
=> let the age of Jamal be x and his father's age be y
=> so , A.T.Q ,
x+y = 40....i)
Find the value of y from here , that's y = 40-x .....
Now, After 4 years ,
=> 3(x+4) = (y+4)
=> 3x+12 = y+4
=> 3x+8 = y ...ii)
putting the value of y in equation ii)
=> 3x+8 = 40-x
=> 3x+x = 40-8
=> 4x = 32
=> x = 8
now ,
=> y = 40-x
=> y = 40-8
=> 32
A set of pens sells for $3. 75 and costs $1. 50 to make. Thirty percent of the profit (the difference between the purchase price and the amount it costs to make) from each set of pencils goes to a school. If 600 sets are sold, what is the amount of money that will go to the school?
Answer:
$405
Step-by-step explanation:
3.75-1.50=2.25
2.25 x 600 = 1350
30 % of 1350 is 405 so it would equal $405

Step-by-step explanation:
using the tangent ratio in the right triangle and the exact valu
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{19\sqrt{3} }[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
[tex]\sqrt{3}[/tex] × y = 19[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
y = 19
--------------------------------------------------
using the cosine ratio in the right triangle and the exact value
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{19\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
[tex]\sqrt{3}[/tex] × x = 38[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
