What value of x is in the solution set of -5x-15>10+20x

Mae Ling earns a weekly salary of $380 plus a 5.0% commission on sales at a gift shop. How much would she make in a work week if

Margarita [4]

Calculate 5% of how much she sold, then add it to her weekly salary.

5% = 0.05

Commission: 4600 x 0.05 = $230

Total pay: 380 + 230 = $610

Match the following reasons with the statements in the given proof. Prove that if two angles are complementary to the same angle

yulyashka [42]

1. --> d

2. --> b

3. --> a

4. --> c

1 is d because that is the only piece of information that sounds like a given.

2 is b because we know that from the given, m∠1 is complementary to m∠2 and in the first problem, m∠1 + m∠2 = 90, they are added together. The definition of complementary angles is "Two angles with measures that, when added together, equal 90 degrees". Same thing with m∠3 and m∠2.

3 is a because since both of the problems equal 90 degrees, you can just take away the 90 and put an equal sign in between the two problems because they equal the same thing.

4 is c because you are subtracting m∠2 from the problems and ending up with just m∠1 = m∠3.

Hope this helps! :)

Find the volume of the following solid:

Nadya [2.5K]

Answer:

390cm³

Step-by-step explanation:

IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.

All you need to do is solve for the volume of each prism and add them up together.

The formula to use to get the volume of a rectangular prism is:

$V=whl$

Where:

V = Volume

w = width

l = length

h = height

Let's get the first one and double it because you have rectangular prisms with the same dimensions:

$V = wlh\\\\V= (5cm)(2cm)(12cm) = 120cm^3\\\\120cm^3 \times 2=240cm^3$

Next we get the rectangular prism in the middle:

Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.

12cm - (5cm + 2cm)

12 cm - 7cm = 5cm

Then we plug it into the formula

$V = wlh\\\\V= (5cm)(6cm)(5cm) = 150cm^3$
