Step-by-step explanation:

$2x + y = 4$

Let's subtitute $x = 1$ for the above equation:

$2(1) + y = 4$

$2 + y = 4$

$y = 2$

The square shown has a perimeter of 32 units. The square is rotated about line k. what is the circumfrence of the base

boyakko [2]

The circumference equal to 25 units

<h3>What is perimeter of square?</h3>

The perimeter of square is 4 times the side.

P= 4* side

The perimeter of the square,

4x = P

Now P is = 32 units then,

32 units = 4(x)

x = 8 inches

So, the diameter of the cylinder formed by the rotation of 8 inches

Now, the circumference of the base is

C = 2πr = πD

If r =8 inches

C = π(8 units) = 8π units

C = 8(3.14) = 25.12 units

Hence, the circumference equal to 25 units

A dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours. At this constant rate, how long does i

Novosadov [1.4K]

Answer:

$\frac{4}{5}$ hour

Step-by-step explanation:

Let x represent time taken by dog to run the 1 and three tenths -mile state fair race.

We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.

We will use proportions to solve our given problem as:

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

We will equate both speeds as:

$\frac{1\frac{3}{10}}{x}=\frac{3\frac{1}{4}}{2}$

$\frac{\frac{13}{10}}{x}=\frac{\frac{13}{4}}{2}$

$\frac{13}{10\cdot x}=\frac{13}{4\cdot 2}$

Cross multiply:

$13\cdot 10\cdot x=13\cdot 4\cdot 2$

$10\cdot x=4\cdot 2$

$\frac{10\cdot x}{10}=\frac{4\cdot 2}{10}$

Therefore, it will take $\frac{4}{5}$ hour to complete $1\frac{3}{10}$ mile state fair race.

What is the value of the shown expression? 33 x 3-2 A) -54 B) -243 C) 243 D) 3

alex41 [277]

We have the following general rule for exponents:

$a^n\cdot a^m=a^{n+m}$

then, in this case we have the following:

$3^3\cdot3^{-2}=3^{3+(-2)}=3^{3-2}=3^1=3$

therefore, the answer is 3
