which equation can be used to find the perimeter of regular with sides if length 12m​

Answer:

For the first question the answer is 50(0.2 + 1)^2 = 72

For the second question it is y = 32

Step-by-step explanation:

In case you need to see how i got it...it's below

For number 1, y is proportional to (x + 1)^2

The equation would be y(x +1)^2 = k(the constant). Then I substituted numbers you gave me in the equation which was : 50(0.2 + 1)^2 = k(72)

For number 2 I used this equation: y (x + 1)^2 = 72. I substituted x for 0.5. The equation will be: y(0.5 + 1)^2 = 72. Then I got 32 for y.

Hope this helps:)

Answer:

Subtract 12

Step-by-step explanation:

Start by subtracting 12

Then multiply both sides by -5

461+1=462

462÷7=66

Your answer is 461

Answer:

461

Step-by-step explanation:

Work backwards.

7 X 66=462

462-1=461

So 461 is the answer

Answer:

It's 4

Step-by-step explanation:

It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.

1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)

Answer:

£0.8

Step-by-step explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

Hence,

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.6 / 2

x = 0.8

Hence, a tin of baked beans cost £0.8

Answer:

£0.80

Step-by-step explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

lol

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.60 / 2

x = 0.80

YES WE GOT IT, a tin of baked beans cost £0.80

Answer:

1. 37

2. 26

3. 26

Step-by-step explanation:

Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.

Answer: y= -17

Step-by-step explanation:

y= 1 - 2x

so when x=9,

y= 1 - 2(9)=1 - 18= -17

Answer:

y=-17

Step-by-step explanation:

y= 1-2x

since x=9, we substitute the x for 9

y= 1-2(9)

then we multiply 2 with 9

y= 1-18

y=-17

Other four Positive whole number is 13

The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.

According to the question

First, we consider that if we add together three equal numbers, the result must be a multiple of three. For example, 7 + 7 + 7 = 21, or 11 + 11 + 11  = 33.

Algebraically, we'd say that n + n + n = 3n.

So this means that if we subtract the first number (the one that's a multiple of 19) from 97, we will have a result that is a multiple of 3.

What could the first number be? 19, 38, 57 or 76 . Any other value is larger than the sum of 7, which is not possible if all the integers are non-negative.

Based on this, we can find all possible sums of the other four numbers, by subtracting each of the numbers above from 96:

96 - 19 = 77

96 - 38 = 58

96 - 57 = 39

96 - 76 = 20

Remember what I said earlier? The other four numbers must add to a multiple of 3. The only one of those sums above that is a multiple of 3 is 39. Therefore, we conclude that the first number is 57, and the other four numbers are each 13 (because 39 / 3 = 13).

Hence, other four number is 13

Answer:

t = 480 seconds

Step-by-step explanation:

Let

Time taken for a water heater to boil water = t

power of the water heater = p

Constant of proportionality = k

t = k/p

240 = k/2000

Cross product

240 * 2000 = k

k = 480,000

Find the time it takes to boil water when the power is reduced to 1000 Watts.

t = k/p

= 480,000/1000

= 480

t = 480 seconds

t = 480 seconds when p = 1000 watts

Answer:

A. 9

Step-by-step explanation:

To solve slope with points, use the equation: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]. In this case it would be: [tex]\frac{7 - (-2) }{-6- (-7) }[/tex]. 7 - -2 is also 7 + 2 or 9. -6 - - 7 is also -6 + 7 or 1. So the final fraction is [tex]\frac{9}{1}[/tex] or 9.
