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

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:

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:

£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:

???? is there more information?

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: 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

Step-by-step explanation:

Because of all the variables in the side lengths, we don't have enough information to use side-angle-side similarity.

We do have two angles of one triangle congruent to two corresponding angles of the other triangle, so we can use angle-angle similarity.

Sides AE and AD are corresponding sides. Sides AC and AB are corresponding.
