Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

Danielle earned $969 last week if she sold $4,400 in electronics merchandise

<h3><u><em>Solution:</em></u></h3>

Given that, Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.

She also earns a base salary of $650 per week.

We have to find how much did she earn last week if she sold $4,400 in electronics merchandise?

Now, we know that, earned amount = base salary + commission

Given that she earns a 7.25% commission on everything she sells

<em><u>So commission earned for selling $ 4400 is given as:</u></em>

commission earned = 7.25 % of 4400

$\text { commission earned }=\frac{7.25}{100} \times 4400=7.25 \times 44=319$

Earned amount = base salary + commission = 650 + 319 = 969

Hence, she earned $969 last week

Find the missing lengths of the sides.

Anarel [89]

Given:

The figure of a right angle triangle.

$a=b$

Hypotenuse = $9\sqrt{2}$ in.

To find:

The missing lengths of the sides.

Solution:

In the given right angle triangle both legs a and b are equal, and hypotenuse is $9\sqrt{2}$ in.

Using Pythagoras theorem, we get

$Hyponteuse^2=Base^2+Perpendicular^2$

$(9\sqrt{2})^2=(a)^2+(b)^2$

$81(2)=(a)^2+(a)^2$ $[\because a=b]$

$81(2)=2(a)^2$

Divide both sides by 2.

$81=(a)^2$

Taking square root on both sides.

$\pm \sqrt{81}=a$

$\pm 9=a$

Side cannot be negative. So,

$9=a$

Thus, the missing side lengths are a=9 in and b=9 in.

Therefore, the correct option is C.

Simplify the expression: –3(–7 + 3z)

aleksandrvk [35]

Hey there! I'm happy to help!

We want to multiply each term inside the parentheses by the number on the outside.

-3(-7)=21

-3(3z)=-9z

Therefore, our expression is 21-9z.

Now you know how to use the distributive property! Have a wonderful day! :D
