Answer:
Height: 8.471
Volume: 2245.641cm3
Step-by-step explanation:
To solve this problem we need to find the volume of the cone, then the volume of the semi sphere, and then, sum all together.
To obtain the volume of the cone, we need to focus our attention in the triangle that already was given to us, since its height is the same as the height of the cone.
We can use the tan(26,7) since it relates the radius of the cone, and its height.
This gives us. h=9/tan(27,9)= 8.471 cm
The volume of the cone is then. 718.629cm3
The volume of the spehere is 1527.012 cm3
FInally the volumen of the toy is the sum of both volumes previously obtained:
2245.641cm3.
Refer the attached picture for a more detailed procedure.
Answer:
$9 is the part, 15% is the percent, and $60 is the whole.
Step-by-step explanation:
$9 is %15 of the whole. This means $9 is the part, 15% is the percent, and the whole is the total cost of the shoes after the discount. The total cost of the shoes after the discount is 60.
Answer:
x=0 and y=−2
keep scrolling it is kind of long
Step-by-step explanation:
−2x+2y=−4,3x−2y=4
−2x+2y=−4for x:
−2x+2y=−4
−2x+2y+−2y=−4+−2y
−2x=−2y−4
-2x/-2=-2y-4/-2
x=y+2
Substitute y +2 for x in3x−2y=4:
3x−2y=4
3(y+2)−2y=4
y+6=4
y+6+−6=4+−6
y=−2
Substitute −2 for y in x=y+2:
x=y+2
x=−2+2
x=0
x=0 and y=−2
Answer:
is 132 enough? We need more info.
Step-by-step explanation:
His projects would need 84+(12*4) inches of rope. This means he needs 132 inches of rope. Do you know how much rope he has?

Perpendicular lines have slopes that are negative reciprocals.
Since the slope of line FG is 3/4, you are looking for a slope that is -4/3.
the slope formula is m= (y₂-y₁)/(x₂-x₁)
you are given one point of the formula (6, -6) so you just need to plug in the options until you get an answer of -4/3
A) (-6 , 10)
m= (10-(-6)/(-6-6)
m = 16/-12
m= -4/3
after getting a slope of -4/3 you can conclude that the answer is
A) (-6, 10)
hope this helped!
