Answer:
Speed of swimmer = 2.34 m/s (Approx.,)
Step-by-step explanation:
Given:
Distance covered in world record swimming = 50 meters
Time taken by free style swimmer = 21.34 seconds
Find:
Speed of swimmer
Computation:
Speed = Distance / Time taken
So,
Speed of swimmer = Distance covered in world record swimming / Time taken by free style swimmer
Speed of swimmer = 50 / 21.34
Speed of swimmer = 2.34 m/s (Approx.,)

Somebody please help me!
This is my question.
Evaluate 12.3p + 11.7r when p = 6 and r = 7.
And then it’s written like this.
12.3(_)+11.7(_)=_+81.9
=_
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
hope it helps

find the area asap i really need help 30 minutes left plzz
Answer:
45mm
Step-by-step explanation:
First, find the whole area of the square, which is 225 mm squared.
Then, we have to find the area of the shaded trapezoid. Remember, the area of the trapezoid is [tex]\frac{h(b^{1}+b^{2} }{2}[/tex]
We get the area of the trapezoid to be 180 mm.
We subtract 180 from 225 mm to get 45 mm as our answer.

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.
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.

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!!!
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.

y - X=-5
y = 2x2-3x-5
PLEASE HELP AND SHOW WORK
(substitution)
Answer:
Step-by-step explanation:
y - x = -5
y = x-5
y = 2x² - 3x - 5
x-5 = 2x² - 3x - 5
2x² - 4x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2, 0
(x,y) = (2,-3), (0,-5)
The Royal Fruit Company produces two types of fruit drinks. The first type is 35% pure fruit juice, and the second type is 100% pure fruit juice. The company is attempting to produce a fruit drink that contains 45% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 260 pints of a mixture that is 45% pure fruit juice?
Answer:
first type of fruit juice (35%) = 4
second type of fruit juice (100%) = 4
Step-by-step explanation:
4×35 = 140
4×100 = 400
400-140 = 260
a piece of work can be completed in 30 days by 10 men. if the work is to be completed 5 days earlier, how many more men are needed? (assume that the men work at the same rate)
Answer:
so, if 10 men can do it In 30 days, that means a total of 300 "man days".
300 man days divided by 25 days would be 12- so 2 more men.
