Answer:

The new value after an increase

of £258 by 43 will be: 368.94

Step-by-step explanation:

As we have to increase £258 by 43 using the multiplier method.

Let 'n' represent the new value after the increase of £258 by 43 using the multiplier method.

Using the formula

n = 258 + percentage increase

   [tex]=258+\left(43\%\:258\right)[/tex]

   [tex]=258\:+\:43\%\:\times 258[/tex]

Factoring out 258

    [tex]=\left(1\:+\:43\%\right)\:\times \:258[/tex]

as 1 = 100 / 100 = 100%

so

   [tex]=\left(100\%\:+\:43\%\right)\:\times \:258[/tex]

   [tex]=143\%\:\times \:258[/tex]

    [tex]=\frac{143}{100}\times 258[/tex]

    [tex]=\:\frac{143\times 258\:\:}{100}[/tex]

    [tex]=\:\frac{36,894\:\:}{100}[/tex]

    [tex]=368.94[/tex]

Therefore, the new value after an increase

of £258 by 43 will be: 368.94

Answer: 18.5227272727

Step-by-step explanation:

1630/44 = 37.0454545455

Therefore 37.0454545455 to 2 decimal places = 37.05

1630/44 divided by 2 » (1630/44) ÷ 2 » 37.0454545455 ÷ 2

= 18.5227272727

Answer:

3704.54545455

Answer:

201.06 in

Step-by-step explanation:

I'm guessing you meant πr² because that's what you use to find the area of a circle.

Anyways, we know what the radius is, it's 8, so now we just need to plug it in.

π8² = 201.06

or you can do

3.14(8²) = 200.96

Using π just makes it more exact.

Answer:

201.1 in (approx.)

Explanation:

ok x so first I will multiply 8^2 by pi, that gives me an infinite decimal.. but after rounding it up to 1d.p, we get 201.1 inches which is your answer

Answer:

Yes, the table shows a proportional relationship

The value of y when x is 11 is 1331

Step-by-step explanation:

Let us check the relation between x and y in the table

∵ x = 4 and y = 64

∵ 64 = 4³

∴ y = x³

∵ x = 5 and y = 125

∵ 125 = 5³

∴ y = x³

∵ x = 6 and y = 216

∵ 216 = 6³

∴ y = x³

∵ x = 10 and y = 1000

∵ 1000 = 10³

∴ y = x³

∵ All the values on the table give the same relation

∴ x and y are proportion

∴ The table shows a proportional relationship

∵ y = x³

∵ x = 11

∴ y = (11)³

∴ y = 1331

∴ The value of y when x is 11 is 1331

Answer:

y = 2x + 4

Step-by-step explanation:

y = mx+b

m represents the slope, and b is the y-intercept

The slope is 2 as it's going up 2 unit squares each time, and the b is 4 because that's where the y-axis gets intercepted.

so the answer is y = 2x + 4

Answer: 32w

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given data

for train one

speed= 50miles per hour

for train two

speed= 60miles per hour

the total distance between both trains=275miles

Step two:

the expression for speed= distance/time

so that, distance= speed*time

let the time be t

we are going to combine both distances

train one distance =50t

train two distance =60t

Hence total distance

50t+60t=275

110t=1=275

t=275/110

t=2.5 hours

It will take 2.5 hours
