Answer:
Can you show the drop down choices?
Answer:
Notice that each edge of the cube is 2 yards long, and the height of the pyramid is 2 yards long too.
The slant height refers to the height of a triangle on its face, which forms a right triangle with the height of the pyramid and half side. Using Pythagorean's Theorem, we have
Therefore, the slant height is the square root of 5, in yards units. (A)
The surface of the composite figure is the sum of the surface area of both volumes.
Therefore, the surface of the composite figure is 32.9 square yards. (B)
The concrete needed will fill the empty space between the cube and the pyramid, so we have to find the difference between their volumes.
Therefore, we need 5.33 cubic yards of concrete to make the planter. (C)
So the original price is $800. And there is a 10% discount, so:
10% = 80
90% = $720
And there is also a $150 gift card applied, leaving us with a final balance of $570 (720-150)
Answer:
<u>graphically</u> :
The graph is symmetrical about the origin.
Then it represents an odd function.
<u>symmetry </u>:
The origin is a center of symmetry.
There are 225 women in the race.
Step-by-step explanation:
Total people in the race = 234
Let,
x represents the number of women in race.
y represents the number of men in race.
According to given statement;
x+y=234 Eqn 1
x=25y Eqn 2
Putting x=25y in Eqn 1
Dividing both sides by 26
Putting y=9 in Eqn 2
There are 225 women in the race.
