The number of 5p, 10p, and
20p coins in a jar are in the
ratio 7:4:3. If there are
5p coins are worth 70p
calculate the total value of
the money in the jar.

Answers

Answer 1

Answer:

Step-by-step explanation:

70p/5=14

14*4=56*10=560p

14*3=42*20=840p

840+560+70=1470

=1470p or (£14.70)

Answer 2

The total value of money in the jar is 270p.

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

The number of 5p, 10p, and 20p coins in a jar are in the ratio 7:4:3.

That means,

Number of 5p coins are 5x, 10p coins are 4x and 20p coins are 3x.

And 5p coins are worth 70p.

That means, x = 70p/5p

x = 14

So,

The total worth of coins are,

= 70p + 80p + 120p

= 270p

Therefore, the worth of the coins are 270p.

Solve for x
2^x= 0.0625(X is an integer)

Answers

Answer:

there you go:)

..................

Answer=x=-4

This question is to do with logs and indices

2^x =0.0625

we know that 2³=8
And log2(8) = 3

*using this form we can solve for x*

2³=8
2^x =0.0625

log?(?) = ?

Both indices have a base of 2 so the log2 stays the same

Instead of 8 we put the 0.0625 in the bracket

So we get
log2(0.0625) = ?
Put this in your calculator and you should get

log2(0.0625) = -4

The universal set is U = {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}. If A = {Monday, Tuesday,Wednesday, Thursday, Friday} and B = {Friday, Saturday, Sunday}, find the indicated set.

A intersect B '

Answers

Answer:

{Monday, Tuesday, Wednesday, Thursday}

Step-by-step explanation:

First we need to get the complement of B i.e B'

B' are the set in the Universal set but that are not in B

B' = {Monday, Tuesday, Wednesday, Thursday}

A= {Monday, Tuesday, Wednesday, Thursday, Friday}

A intersect B ' are the days of the week that are common to both sets;

A intersect B ' = {Monday, Tuesday, Wednesday, Thursday}

Green crescent should be 11
2+2+11=15
Pink trapezoid should be 15
30-15=15
15=15

Answer:

Pink Trapezium = 30   as 30 x 1 = 30

Purple Diamond = 2    as 2 x 2 = 4

Green Moon = 7.5     as it shares the line with 4 it goes 4 x 7.5 = 30

The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.

When we show the values see below. We have 30 also for the second line so both lines are equivalent

Step-by-step explanation:

I would multiply as addition is just too easy.

Pink Trapezium is 1 x 30 = 30  = 30/1 = 30 value

Purple diamond = 2 x 2 = 4  = 4/2 = 2 value

Green Moon is 30/4 = 7.5 value

So, Christian has a collection of 18 shark teeth. He identified them as 6 tiger shark teeth, 8 sand shark teeth, and the rest as bull shark teeth, I don’t get the 2nd question, can anyone help??

Answers

Answer:

So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.

Step-by-step explanation:

So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.

Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.

Let x represent the number of bull shark teeth.

So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.

18 = 6 + 8 + x

18 = 14 + x

subtracting 14 from both sides, we have

18 - 14 = 14 - 14 + x

4 = 0 + x

4 = x

x = 4

So, the number of bull shark teeth is 4.

The mean of the numbers 22,18,(2y+1),10 and 20 is 15.
find the median.​

Answers

Answer:

Median is 18

Step-by-step explanation:

Firstly you have to fine y by using your mean

Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15

22+18+2y+1+10+20 over 5 =15

71+y over 5 =15

Cross multiple

71+y=75

y=4

22,18,9,10, 20

Rearrange

9,10,18,20,22

The median is 18
