Answer:
750ft^3
Step-by-step explanation:
Given:
Volume of cone a=48ft^3
Radius of a=12 inches
Radius of b=30 inches
Volume of cone b=?
The linear state factor=ratio of the radio
=30/12
=2.5
Volume scale factors=linear state factor^3
=2.5^3
=15.625
Volume of Cone B= volume of Cone A × volume scale factor
=48 × 15.625
= 750 ft^3
Answer:
3(43)=192
192=192
True
Step-by-step explanation:
so my answer is YES
Answer:
a: is false the base is an rectangle
b: is true because you multipluy the hight depth and length. that gives you 81
c: is correct because 9 times 4 is 36
d: is incorrect because you need to double all numbers for the volume to double

Answer:
(0,-5) and (-4,3) are the points to the equations.
Step-by-step explanation:
Solution:
Step 1: Make an equation for y to substitute to the first equation.
x^2+y^2=25
y=-2x-5
Step 2: Substitute the y-value to the first equation.
x^2+(-2x-5)^2=25
x^2+4x^2+20x+25=25
Our x-values would be 0, and -4.
Step 3: Solve for the y-values by substituting 0 and -4 to the equation y=-2x-5.
y=-2(0)-5=-5 and makes the ordered pair (0,-5)
y=-2(-4)-5=3 and makes the ordered pair (-4,3)
Therefore our answers would be (0,-5) and (-4,3)
Answer:
She spend 6y dollars on scarves.
Step-by-step explanation:
The question states that y represents the number of scarves she bought, so the first and second statements would be incorrect. You don't know how much she spent in total, so the fourth statement would also be wrong. So it's the third statement.
Also, you can just do 2*(3y), which is 6y.
