A pile of sand has a weight of 60 kg
The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of the sand in each bag

Answers

Answer 1

Small bag = 2x

Medium bag = 3x

Large bag = 7x

2x + 3x + 7x = 60

12x = 60

x = 60/12

x = 5

Small bag = 2(5) = 10 kg

Medium bag = 3(5) = 15 kg

Large bag = 7(5) = 35 kg

Done.

Answers

Answer:

y = 2327.49 ---> 25 hrs

starting plot points (0,640) and ending (25, 2327.49)

Step-by-step explanation:

b = 640

r = 5.3% = 0.053

t = 25

y = 640 ( 1 + 0.053)^25

y = 640 ( 1.053)^25

y = 2327.49 ---> 25 hrs

Which scenario is best represented by a linear function?
A
The area of a square, A, where the length of each side of the square is represented by
S (A= s?)
The perimeter of a square, P, where the length of each side of the square is
B represented by s
(P = 4s)
The surface area of a cube, A, where the length of each side of the cube is
C represented by s
(A = 6s )
The volume of a cube, V, where the length of each side of the cube is represented by
s(V = $)​

Answers

Answer:

P=6s

Step-by-step explanation:

to understand thisyou need to know about:linear functiontips and formulas:a linear function is function with two variables one dependent another one is independentlet's solve:

since we can see what linear function is

the second condition is the best fit

What is the perimeter of the triangle?

Answers

Answer:

The answer is 36

Step-by-step explanation:

First, suppose that each square is the unit length, and from it the length of the hall can be calculated and we find that it is equal to 10, then to find the value of the other two we drop a column of the vertex of the triangle on the base and find that its length is 12 units and it divides the base into two equal halves, so we determine that each side equals 13 units using Pythagoras and it will be The lengths of the sides of the triangle are 10, 13, 13

Then the perimeter is

your answer dude mark me as brainelist give me thanks

Answer:

5x + 16

Step-by-step explanation:

3(x+2) +2 ( x+5)

divide the expression into 2 separate ones:

3(x + 2) and 2(x + 5 )

Now for  3( x + 2 ) Multiply 3 with x and 3 with 2. This gives:

3x + 6

Now for 2( x + 5 ) Multiply 2 with x and 2 with 5. This gives:

2x + 10

Now since there is a '+' sign between  3( x + 2 ) and 2( x + 5 ), the expression will be:

3x + 6 + 2x + 10

You can simplify the like terms together:

3x + 2x + 10 + 6

= 5x + 16

Answers

Interest is the amount of money added on an amount invested. He have doubled her investment after 18 years

Compound interest

The formula for calculating the compound interest is expressed as

A = P(1+r)^t

Given the following parameters

P = $500

r = 4%= 0.04

A= $1000  (doubled)

Substitute

1000 = 500(1+0.04)^t

2 = 1.04^t

t = ln2/ln1.04

t= 17.67 = 18years

Hence he have doubled her investment after 18 years

Perhaps you think this is a harmless activity - but you are wrong. It can be dangerous. A study revealed that every year about five hundred people end up in a British hospital after an accident involving a biscuit. How on Earth do they do it?Some people fall off their chairs even before they sit down to have tea. How? They stand on the chairs to reach the biscuit tin, and you can guess what happens next. Others are hit in the eye by bits of biscuit flying through the air, and a few hit themselves in the eye with a biscuit. Quite a lot dip their biscuits in hot tea, then burn their mouths - or, if the biscuit breaks in the tea, they burn their fingers. Some people choke, and some break teeth. Some are even bitten (not by the biscuits - but by their pets!).Most of these accidents sound unlikely, but they are all true. However, none of them is as weird as the following one. A man had to be rescued after he tried to pick up a biscuit he had dropped in the street. It had landed in some wet concrete and perhaps you can guess what happened next.That, surely, is the most extraordinary biscuit-related accident ever.Example: Some people can fall off their chairs before they even have their tea and cake.1 Drinking tea in conjunction with eating a cookie has a long tradition in ________________________.2 According to research, about ________________________ people end up in the hospital each year as a result of biscuit-related accidents.3 Reaching for ________________________ can also end unhappy.4 Soaking a cookie in tea can lead to ________________________ or fingers.5 A man needed help after trying ________________________ that fell into wet concrete. 1,2,3,4,5,7,7,7,8,8What is the median What does (4+1)(x+2x) simplify to? 16,000*y=220,000 what does y equal Black Soldiers who fell into the hands of Confederate soldiers were treated as prisoners of war.
