Answer:

12/16 is greater than 0.12.

Step-by-step explanation:

0.12 = 12/100 = 6/50 = 3/25

12/16 = 3/4.

So, 12/16 is greater than 0.12.

Answer:

12/16 is greater than

12/16 as a decimal would be .75 so its greater than .12

Answer:

y = 4x - 8

Step-by-step explanation:

(-1, -12) & (4, 8)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(8 - (-12)) / (4 - (-1))

Simplify the parentheses.

= (8 + 12) / (4 + 1)

= (20) / (5)

Simplify the fraction.

20/5

= 4

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = 4x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (4, 8). Plug in the x and y values into the x and y of the standard equation.

8 = 4(4) + b

To find b, multiply the slope and the input of x(4)

8 = 16 + b

Now, subtract 16 from both sides to isolate b.

-8 = b

Plug this into your standard equation.

y = 4x - 8

This is your equation.

Check this by plugging in the other point you have not checked yet (-1, -12).

y = 4x - 8

-12 = 4(-1) - 8

-12 = -4 - 8

- 12 = -12

Your equation is correct.

Hope this helps!

Answer:

£6368

Step-by-step explanation:

You can start by making a formula, which will be:

100/100=1

1.5/100=0.015

1+0.015=1.015 (your multiplyer)

6000*1.015^n= your money after 4 years

(n represents the number of years)

Now you just put in the number of years:

6000*1.015^4=6368.181304

Now round:

Answer:

B. 12.5%

Step-by-step explanation:

Find how much was unused:

120 - 105

= 15

To find what percent this is, divide it by 120:

15/120

= 0.125

Multiply this by 100:

0.125(100)

= 12.5

So, 12.5% of the wire went unused

The correct answer is B. 12.5%

Step-by-step explanation:

the explanation is given in the pictures...

The road roller is turning at the rate of [tex]18.3rev/minute[/tex]

To get our answer, first note that

[tex]speed=\dfrac{distance}{time}[/tex]

since the distance travelled by the road roller can be gotten by

[tex]distance= circumference\times revolutions[/tex]

our speed formula can be expressed as

[tex]speed=\dfrac{circumference\times revolutions}{time}[/tex]

making the number of revolutions the subject of the formula, we get

[tex]revolutions=\dfrac{speed \times time}{circumference}[/tex]

carrying out the following substitutions

[tex]speed=3miles/hour=\frac{3\times63360}{60}inches/minute=3168inches/minute\\time=1minute\\circumference=2\times3.14\times\frac{55}{2}=172.7inches[/tex]

we can now calculate the number of revolutions

[tex]revolutions=\dfrac{speed\times time}{circumference}\\\\=\dfrac{3168\times 1}{172.7}\approx18.3rev/minute\text{ (to the nearest tenth)}\\\\[/tex]

Answer:

£469

Step-by-step explanation:

So 6 years mean it has depretiatied to 5.5*6 = 33% meaning the car is worth 67% of what it was originally worth

First do 700 / 100 to find what the car is equal to when it's 1% which is 7, after than multiply its new value of 67%,

so 7*67 = £469

Answer:

$469

Step-by-step explanation:

To find the amount of money that the car loses in value every year, multiply the price of the car by the rate its value depreciates at in decimal form.

The car depreciates at a rate of 5.5% per year. To find 5.5% in decimal form, move the decimal point to left twice. So, 5.5% in decimal form is 0.055.

700 * 0.055 = 38.5

The car loses $38.50 in value every year, so the car's value will depreciate by 6 times that amount in 6 years.

$38.50 * 6 = $231, so the car will lose $231 in value after 6 years.

700 - 231 = 469

The car will be worth $469 in 6 years.

============================================================

Work Shown:

1/4 = 0.25

7/10 = 0.70 = 70%

We are told that 0.25 gallons of water fills 70% of the pool

We want to find how many gallons of water (call it x) are needed to fill 100% of the pool.

Set up the proportion below and solve for x

(0.25 gallons)/(70% filled) = (x gallons)/(100% filled)

0.25/70 = x/100

0.25*100 = 70x ....... cross multiply

25 = 70x

70x = 25

x = 25/70

x = (5*5)/(5*14)

x = 5/14 gallons

----------------------------------------

An alternate method:

1/4 gallons = 7/10 pools filled

(10/7)*(1/4 gallons) = (10/7)*(7/10 pools filled)

(10*1)/(7*4) gallons = (10*7)/(7*10) pools filled

10/28 gallons = 1 pool filled

(5*2)/(14*2) gallons = 1 pool filled

5/14 gallons = 1 pool filled

In the second step, I multiplied both sides by 10/7 so that the "7/10" turns into "1".

----------------------------------------

Yet another alternate method:

1/4 = 10/40

7/10 = 28/40

We need 10/40 gallons of water to fill 28/40 of one pool. We can multiply both fractions by 40 to indicate that 10 gallons of water will fill up 28 pools.

So we have this ratio

10 gallons : 28 pools

Dividing both parts by 28 tells us how many gallons are needed for one pool

10 gallons : 28 pools

10/28 gallons : 28/28 pools

10/28 gallons : 1 pool

5/14 gallons : 1 pool

Answer:

a) 2 + 1 = 3

Formula of area

AREA = LENGTH (multiply) BREATH

Answer:

The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.

In this case, 4 is the base, and 7 is the height.

So we have: Area = 1/2(4)(7)

Simplifying: Area = 2(7), Area = 14.

The area of the triangle is 14 meters squared.
