Use the number line to show and explain why 4/10 ÷ 2 and 4/10 × 1/2 both equal 2/10

Answers

Step-by-step explanation:

When you divide by a number, you basically are multiplying by the reciprocal

The reciprocal of 2 is 1/2

4/10 ÷ 2 = 4/10 × 1/2 = 2/10

4/10 × 1/2 = 2/10

Using a number line,

Start at 4/10 and move down by 2 until you reach 0

Start at 4/10 and move up by 1/2 from 0 until you reach 4/10

pls help asap! what's the area?

Answers

Answer:

519 meters square

Step-by-step explanation:

16 x 16 = 256

256 / 2 = 128

11.5 + 34 = 391

128 + 391

100 + 300 = 400

20 + 90 = 110

8 + 1 = 9

400 + 110 + 9 = 519

Answer:

I believe the answer is 519m

Step-by-step explanation:

first you seperate the triangle from the rectangle then solve the area for the rectangle 11.5•34=319  then solve the area for the triangle 16•16=256    

256÷2=128    then add 128+391= 519     i hoped this helped you :-)

a cone is a solid made from a disc, a point not in the same plane as the discs and all points between them. true or flase?

Answers

Answer:

False.

Step-by-step explanation:

A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.

Mathematically, the volume of a cone is given by the formula;

[tex] V = \frac{1}{3} \pi r^{2}h[/tex]

Where;

V is the volume of the cone.

r is the radius of the base of the cone.

h is the height of the cone.

Members of a baseball team raised $1479.25 to go to a tournament. They rented a bus for $800.50 and budgeted $45.25 per player for meals. Write and solve an equation which can be used to determine pp, the number of players the team can bring to the tournament.

Answers

Answer:

15 players

Step-by-step explanation:

First, you might want to exclude out how much it cost to rent a bus.

1479.25 - 800.50 = 678.75

After that, the remaining amount of money is how much money is spent altogether for the basketball player's meal, since each player had the same budget for the meal, it made the question easier.

678.75 ÷ 45.25 = 15

Answers

Answer:

784000J or 784KJ

Step-by-step explanation:

Kinetic energy (KE) can be represented with the formula

KE = 1/2(MV²)

where

M = Mass of object (Kg) =2000kg

V = velocity or speed of object in metre per second (m/s or ms^-1) = 28m/s

therefore

KE = 1/2(mv²) becomes

KE = (1/2) X 2000 X 28 X 28

KE = 784000Joules

Write the equation for a circle with the center (90,195) and a radius of 88

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the Circles.

The centre of the circle is given as, (h, k)

The equation in form of centre and radius of the circle is given as,

===> (x-h) ^2 + (y-k) ^2 = r^2

hence, the equation would be,

===> (x-90)^2 + (y-195)^2 = (88)^2
