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:)

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:

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:

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: 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

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.

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

Step-by-step explanation:

Red marble probably currently: 12/32 = 3/8

Guess and check (using the multiple choice answers):

F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5

G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5

H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5

J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5

K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5

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
