Answer:

The unit rate is accurately $\frac{1}{4}$ (km/minute)

Step-by-step explanation:

(1,1/4) means that the vehicle traveled 1/4 km within 1 minute.

The unit rate for this problem is also known as the speed of the vehicle.

So to find the speed, you need to use distance over time.

---> Unit rate: $\frac{1}{4}\\$ / 1 = $\frac{1}{4}$ (km/minute)

(2,1/2) means that the vehicle traveled 1/2 km within 2 minutes.

Same process:

---> Unit rate: $\frac{1}{2}$ / 2 =

Because of this, the unit rate is accurately $\frac{1}{4}$ (km/minute)

Graph an inequality on a number line: 15>m

barxatty [35]

When the sign is ≤ or ≥ ("less/greater than <u>or equal to</u>"), the dot if filled in.

When the sign is < or >, the dot is not filled in/open circle.

15 > m

[15 is greater than m, or m is less than 15]

Since m is less than 15, the arrow is going to the left (the numbers to the left are less than 15)

You planted 488 acres of corn last season. You sold all your corn: 8,120 bushels in August and 46,100 bushels in September. What

strojnjashka [21]

Add August and September for total amount of bushels:

46,100 + 8,120 = 54,220 total bushels

Divide total bushels by total acres:

54,220 / 488 = 111.1 = 111 bushels per acre

HELP!!!!

Answer:

$8 y^{50}$

Step-by-step explanation:

Given (64 y Superscript 100 Baseline) Superscript one-half.

Let us write it into an equation.

$\left(64 y^{100}\right)^{\frac{1}{2}}$

Apply radical rule: $\sqrt[n]{a}=a^{\frac{1}{2}}$ and $a^{m+n}=a^m+a^n$

$\begin{aligned}\left(64 y^{100}\right)^{\frac{1}{2}} &=\sqrt[2]{64 y^{100}} \\&=\sqrt[2]{8^{2} y^{50} y^{50}} \\&=\sqrt[2]{8^{2}\left(y^{50}\right)^{2}} \\&=8 y^{50}\end{aligned}$

Hence, $8 y^{50}$ is equivalent to (64 y Superscript 100 Baseline) Superscript one-half.
