Answer:

9x^2

Step-by-step explanation:

It is given that:

x ( x + y ) = 27

If one manipulates the equation, by dividing by x, they get:

x + y = 27/x

It is also given that:

y ( x + y ) = 54

Again, manipulate the equation, only this time, divide by y,

x + y = 54/y

It is obvious that;

x + y = x + y

Yet this was proven;

x + y = 27/x

x + y = 54/y

Therefore, the following has to be true;

27/x = 54/y

To sove the proportion, use cross products;

27/x = 54/y

54x = 27y

Inverse operations:

54x = 27y

/27     /27

y = 2x

Substitute;

(x + y)

y = 2x

= (x + 2x)

= 3x

Now solve:

(3x)^2

9x^2

Step-by-step explanation:

4×10^22

2.9×10^-33

the "e" basically represents 10 raised to some power. that power is the number to the right of it. in this case, that's to the power of 22 and -33, respectively

There are are 100 Natural Terms present there.

given:

12, 13, 14, ......111.

first term, a= 12

d= 13-12= 1

[tex]a_n[/tex] = 11

Now,

[tex]a_n = a+ (n-1)d\\[/tex]

111 = 12 + (n-1) 1

111-12= n-1

n-1 = 99

n= 100

Hence, there are are 100 Natural Terms present there.

Answer:

1/2

Step-by-step explanation:

We do change in y over change in x

Formula for Rate of Change on Slope

y2-y1/x2-x1

For Y

We use coordinate (-2, -4)

-4--2

= -2 - -4

= 2

For X

We use coordinate (0, -4)

0 -- 4

= 0 + 4

= 4

Now we put y over x to find the rate of change in slope

2/4, simplified would be 1/2

Answer:

Step-by-step explanation: 2 plus 5

7 <50

Answer:

x = 22.5

Step-by-step explanation:

2x + 5 > 50.

We do inverse operations sooo:

2x + 5 - 5 > 50 - 5.

50 - 5 = 45.

Then we do 2x ÷ 2 and 45 ÷ 2.

45 ÷ 2 = 22.5.

To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.

Answer:

0; (0, 0); 144; (3, 144)

Step-by-step explanation:

Y = distance (m)

X = time (hr)

X = 48x

If a car travels for 0 hours, it will travel __ mile(s).

y = 48x

Plug in 0 hours for x (time in hours)

y = 48(0)

Any number mutliplied by 0 equals 0

y = 0

If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).

(0, 0) limits our options to graphs B and D

Car travels 144 miles in 3 hours

To find how many miles it travels in 1 hour, divide 144 miles by 3 hours

144 ÷ 3 = 48

In 1 hour, a car travels 48 miles

If 48 × 3 = 144, then 48 × 4 = ?

48 × 4 = 192

When looking at graph D, there are 4 lines above 0

Counting by 48, it perfectly fits 192 by the fourth line

From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting

Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144

Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

Since the question provided the diameter instead of radius, the diameter is 20 feet

Answer: well the diameter would be 20ft. If you meant to ask for the circumference then its 62.857ft

Step-by-step explanation:

Diameter of a circle is 20​ feet.

Hence it's Radius = 20/2 = 10 ft

We know circumference = 2πr

Circumference = 2 × 22/7 × 10 ft

Circumference = 44 × 10/7= 440/7

Circumference = 62.857 ft
