Evaluate 12.3p + 11.7r when p = 6 and r = 7.
And then it’s written like this.
12.3(_)+11.7(_)=_+81.9
=_
Answers
Method:
First place the replace of p and r using brackets.
= 3(6) + 11.7(7)
3 times 6 is 18 and 11.7 times 7 is 81.9
= 18 + 81.9
add one and one together you get
= 99.9

A cone has a volume of 98 cm.
The radius of the cone is 5.13 cm.
Work out an estimate for the height of the cone.
Answers
Answer:
3.56 cm.
Step-by-step explanation:
1/3 π r^2 h = V
1/3 π (5.13)^2 h = 98
h = 98 / (1/3 π (5.13)^2)
= 98 / 27.55899
= 3.556.
Cone is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
If the volume and radius of a cone are 98 cm and 5.13 cm.
The height of the cone is 3.56 cm.
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3πr²h.
Example:
The cone has a radius of 2 cm and a height of 3cm.
The volume of a cone:
= 1/3 x 3.14 x 4 x 3
= 12.56 cm³
We have,
Cone:
Volume = 98 cm
Radius = 5.13 cm
Height of the cone = h
The volume of a cone:
V = 1/3πr²h
98 = 1/3 x π x (5.13)² x h
[ Take π = 3.14 ]
98 = 1/3 x 3.14 x 26.31 x h
Multiply 3 on both sides.
98 x 3 = 3.14 x 26.31 x h
Divide both sides by (3.14 x 26.31).
h = (98 x 3) / (3.14 x 26.31)
h = 294 / 82.61
h = 3.56 cm
Thus,
If the volume and radius of a cone are 98 cm and 5.13 cm.
The height of the cone is 3.56 cm.

What is the answer?
Answers
Answer: D
Step-by-step explanation:
First, you have to multiply 2 by 7, because m=7. Then you have to multiply7 by -1 because n=-1. So on the top, you will get 14- -7. Now on the bottom, its just 7 + -1, which is 6. When there is a minus sign and a negative sign next to each other, for example 14- -7, you have to add. Next, you had 14 and 7 to get 21. Finally, you have to divide 21/6 and you get 3.5, which as a fraction is 7/2.

2/3 + 3/4 + 4/2. If a fraction appears in your answer, it should be in simplified form.
Answers
2/3 * 4/4 = 8/12
3/4 * 3/3 = 9/12
4/2 * 6/6 = 24/12
we can then add the numerators of each fraction
8 + 9 + 24 = 41
so our answer is 41/12
we can not simplify any further and thus get

A scoop of ice cream in the shape of a whole sphere sits in a right cone. the radius of the ice cream scoop is 2.5 cm and the radius of the cone is 2.5 cm. How tall must the height of the cone be to fit all the ice cream without spilling if it melts? SHOW ALL YOUR WORK!!!
Answers
Answer:
(At least) 10 centimeters.
Step-by-step explanation:
The radius of the ice cream scoop is 2.5 cm and the radius of the cone is also 2.5 cm.
We want to determine the height of the cone such that it will fit all of the ice cream when it melts without any spilling.
First, we will find the volume of the ice cream scoop. The volume for a sphere is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Since the radius is 2.5 cm, the volume of the full ice cream scoop is:
[tex]\displaystyle V=\frac{4}{3}\pi (2.5)^3[/tex]
Use a calculator:
[tex]V\approx 65.4498\text{ cm}^3[/tex]
The volume of a cone is given by:
[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]
The radius of the cone is 2.5 cm. Therefore:
[tex]\displaystyle V=\frac{1}{3}\pi(2.5)^2h=\frac{1}{3}\pi(6.25 h)=\frac{6.25\pi}{3}h[/tex]
The volume of the cone should be equal to the volume of the scoop. So:
[tex]\displaystyle 65.4498=\frac{6.25\pi}{3}h[/tex]
Solve for h:
[tex]\displaystyle h\approx 65.4498\Big(\frac{3}{6.25\pi}\Big)=10\text{ cm}[/tex]
The height of the cone should be (at least) 10 cm.
