7. A cone has a volume of 942 cubic inches
and a height of 9 inches. What is the radius of
the cone?
Answer:
Step-by-step explanation:
V of a cone V=3.14* r^2*h/3
942=3.14*r^2*9/3
r^2=942/(3.14*3)=100
r=sqrt100=10
The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.
Calculation of the radius of the cone;
Since there is a volume of 942 cubic inches and a height of 9 inches
We know that
Volume of a cone V=[tex]3.14* r^2*h/3[/tex]
So,
[tex]942=3.14*r^2*9/3\\\\r^2=942/(3.14*3)=100[/tex]
r =[tex]\sqrt 100[/tex]
=10
hence, The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

how to calculate the volume of a cylinder if the height is 9.25 cm and the base is 6.5 cm
Answer:
306.94 cm
Step-by-step explanation:
The formula for volume of a cylinder is pi×r^2×h. Im assuming that you mean that the base is 6.5 cm in diameter so in this case you would plug in the values and do pi×3.25^2×9.25 and get 306.94 cm

Step-by-step explanation:
Answer:
the value of 7x-y is -14.
Step-by-step explanation:
When x=2 and y=4,
To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.
7x - y = 7(2 - 4)
14 - 28
= -14.

Joey is building a doghouse. He measures the lengths of two sides and the hypotenuse to make sure the boards create a right triangle.
Which of the measurements below could be used to create the right triangle?
5 in, 7 in, 12 in
8 in, 12 in 14 in
5 in, 9 in, 11 in
6 in, 8 in, 10 in
pleasee help mee
Answer: 6in, 8in, 10in
6 squared + 8 squared equals to the radical of 100, which equals to 10 because 10 squared is.. 100
The measurements that can be used to build a right-angled triangle are
[tex]6 in, 8 in, 10 in[/tex]
The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship
[tex]x^2+y^2=z^2[/tex]
The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since
[tex]5^2+7^2=74\ne12^2[/tex]
The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since
[tex]8^2+12^2=208\ne14^2[/tex]
The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since
[tex]5^2+9^2=106\ne11^2[/tex]
The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since
[tex]6^2+8^2=100=10^2[/tex]
So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

What is the solution to the system of equations below?
y- x-3 and x = -10
0 (-10,-7)
0 (-10,-1)
0 (-7, -10)
0 (-1,-10)
Answer:
(-10,-7)
Step-by-step explanation:
the given equations: y=-3 and x=-10
we can substitute the x in the first equation as -10.
y=(2/5×-10)-3
simplify
y=(2/1*-2)-3
y=-4-3
y=-7
the y value is -7
we actually have the x value given as -10 (in the system)
So the answer is (-10,-7)

Irene says the equation 9x+15=3x+15 has no solution because 9x is greater then 3x. is he right yes or no and explain why
Answer:
This equation has one solution, if x = 0
Step-by-step explanation:
Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.
Answer:
X=0
Step-by-step explanation:
If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

Which expression represents the area of the vegetable garden in square yards?
8x2 + 54x + 27
12x2 - 27
8x2 + 60x - 27
12x2 + 48x - 27
Answer:
I think is 12x2 +48x-27 but I'm confused
Answer:
[tex]A=12x^2+48x-27[/tex]
Step-by-step explanation:
Area of a Rectangle
The image shows a rectangular vegetable garden with different crops.
The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.
The area of a rectangle is:
A = WL
[tex]A=(2x+9)(6x-3)[/tex]
Operating:
[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]
[tex]A=12x^2-6x+54x-27[/tex]
Simplifying:
[tex]\boxed{A=12x^2+48x-27}[/tex]
