Answer:

The time it takes to boil 2.2 litres of water is approximately 141 seconds

Step-by-step explanation:

The given parameters are;

The relationship of the variables, T and A is a proportional, therefore, we have;

T ∝ A, or T/A = k = Constant of proportionality

The time it takes to boil 2.8 liters of water = 180 seconds

∴ When A = 2.8 litres, T = 180 seconds, from which we have;

k = T/A = 180 s/(2.8 L) = 450/7 s/L

k = 450/7 s/L

When A = 2.2 litres, we have;

T/A = k

∴ T = k × A

Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;

T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141.[tex]\overline{428571}[/tex] s

The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141.[tex]\overline{428571}[/tex] seconds ≈ 141 seconds given to the nearest second.

Answer:

Side A = 4

Side B = 5

Side C = 6

Step-by-step explanation:

In the following equation, variable a is the length of Side A

a + (a + 1) + (a + 2) = 15

a + a + a + 1 + 2 = 15

3a + 3 = 15

     - 3    - 3

3a (÷ 3) = 12 (÷ 3)

a = 4

Side A = 4

Side B = (a + 1) = (4 + 1) = 5

Side C = (a + 2) = (4 + 2) = 6

Answer:

It might be C if im wrong sorry

Step-by-step explanation:

simple just multiply 10X25X21.5 for A and the same for B

Answer:

the answer is d

Step-by-step explanation:

Answer:

The answer is B, C, and D

Step-by-step explanation:

If you simplify each of those ratios, they'll be equivalent

Answer:

B and C

Step-by-step explanation

The first one is B because 2/8 is 4 and 10/20 is 10

The second one is C because 8x3 is 24 and 20x3 is 60

My teacher always says everything you do to one side you have to do to the other :)

Answer:

[tex]5\frac{1}{8}[/tex]

Step-by-step explanation:

5 3/4 = 23/4

(23/4)2 = 46/8

46/8 - 5/8 = 41/8 = 5 1/8

Answer:

The box would be 14

Step-by-step explanation:

It would be 14 because 7/14 is equal to 1/2. And 2/4 is also equal to 1/2.

Answer:

7/14

Step-by-step explanation:

Have a nice day.....

Step-by-step explanation:

step 1. a12 = -5(12) + 32

step 2. a12 = -60 + 32

step 3. a12 = -28.

Answer:

3) 2[tex]x^{2}[/tex] + 3x - 1

Step-by-step explanation:

A quadratic expression is an expression involving a squared term

It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0

// note that here b and c can be equal to 0

1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0

2) 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.

3) 2[tex]x^{2}[/tex] + 3x - 1 is correct

4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex]  + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

Answer:

2x2 + 3x - 1

Step-by-step explanation:

awnser im believe it is 24 i think

Answer:

20 units square

Step-by-step explanation:

do the Pythagoras theorem

a²=b²+c² ⇒ a=√b²+c²

if b is 4 and c is 2 an a is the unknown

so a=√(4)²+(2)²

a=√20

then get the rule of the area of the square

Area of the square= s²

s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)

so s²=20

Area of the square=20 units square

Answer:

1st time: 50% chance or 8/16 chance

2nd time: 46% chance or 7/15

I can try again if its wrong

Answer:

7/30

Step-by-step explanation:

8/16 that she picks a red cube.

7/15 that she picks another red cube after keeping the first red cube.

multiply 8/16 (1/2) times 7/15 to get 7/30 as your final answer

Answer:

D

Step-by-step explanation:

Every input can only have one output for it to be considered a function. There are repeats of x values with different y values in all of these except for D so D is the correct answer.

Answer:

-1

Step-by-step explanation:

the slope of this one is y=x-21

in order for it to be perpendicular the sign changes and the slope flips

but because the slope is 1 you just change the slope to -1

Answer:

13 1/3 pounds

Step-by-step explanation:

Hi! Each bad weighs 2 2/3 pounds. There were 5 bags bought so we multiply. Here is the expression:

2 2/3 x 5 = x

Now we need to convert 2 2/3 into an improper fraction, which is 8/3.

Easy! Now

8          5         40

-      x    -     =    -

3           1          3

*I tried to set it up like fractions.*

Simplify 40/3 and you get 13 1/3

Answer:
