In the video Mouse Count, Miss Ashley read a book about a snake that captured mice and placed them one-by- one in a jar for his

spin [16.1K]

Based on the fact that the snake was placing the mice one - by - one into a jar, this is A. Combining sets.

<h3>What does combining sets entail?</h3>

When sets are combined, it means that numbers from a certain set of variables are combined with those from another set.

The snake had captured the mice separately which means they were in different sets. Putting them into one jar means they are being combined so this is combining sets.

Find b, given that a = 20, angle A = 30°, and angle B = 45° in triangle ABC

Kamila [148]

<span>The side b is opposite to the angle B, applying the law of the sines, we have:

</span> $\frac{a}{sinA} = \frac{b}{sinB}$
$\frac{20}{sin30^0} = \frac{b}{sin45^0}$
$\frac{20}{ \frac{1}{2} } = \frac{b}{ \frac{ \sqrt{2} }{2} }$
$20* \frac{ \sqrt{2} }{2} = b* \frac{1}{2}$
$\frac{20 \sqrt{2} }{2} = \frac{b}{2}$
$2*b =2*20 \sqrt{2}$
$2b = 40 \sqrt{2}$
$b = \frac{40 \sqrt{2} }{2}$
$\boxed{b = 20 \sqrt{2} }$

Write and solve an equation for the following word problem. Define your variable.

marshall27 [118]

Answer:

The variable is the number of clothes sold 'x'.

The equation is: $118.50=100+0.25x$

The number of clothes sold by Lynn are 74.

Step-by-step explanation:

Let the number of pieces of clothes sold be 'x'.

Given:

Earning of Lynn per cloth is $0.25.

Fixed earning of Lynn per day is $100

Total earning after selling 'x' clothes is $118.50.

Variable: Number of clothes 'x'.

Equation:

Earning of Lynn for 1 cloth = $0.25

∴ Earning of Lynn for 'x' clothes = $0.25\times x=0.25x$

Now, total earning of Lynn is the sum of fixed earning and earning from selling 'x' clothes. Therefore,

Total earning = Fixed earning + Earning for 'x' clothes

⇒ $118.50=100+0.25x$

Solution:

Add -100 both sides and then divide the result by 0.25 both sides. This gives,

$118.50-100=100-100+0.25x\\0.25x=18.50\\x=\frac{18.50}{0.25}=74$

Therefore, the number of clothes sold by Lynn are 74.
