Answer:

Her pay for the week= $ 611.325

Step-by-step explanation:

Sallie is paid $ 11.40 per hour for regular hours.

The total regular hours worked during the week are

Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours

She works overtime during the week

Monday + Tuesday + Wednesday = 2+ 1/4+  1 1/2=  2+ 1/4 + 3/2

= 8 +1+ 6/4=15/4 = 3 3/4 hours

Over the weekend she works five hours .

So the total pay would be

$ 11.40( 38 ) + $ 11.40( 1.5) (  15/4) + $ 11.40 ( 2) ( 5)

= 433.2 + 64.125 + 114.0

= $ 611.325

An engineer wants to make a 60% cement mixture. How many pounds of an 80% cement mixture must she mix with 14 pounds of a 50% mi
vladimir2022 [97]
In 14 pounds of a 50% mixture we have 0.5*14=7pounds of cement
lets think that we need x pounds of mix of an 80% cement so in that mix we will have 0.8x pounds of cement. If we'll mix both we wiil have (14+x)pounds of mix and  we have (0.8x+7) cement on it.

in mixture mix there are 60% of (x+14)pounds of cement so it is 0.6(x+14) of cement

make equation (sum of mix)
0.6(x+14)=0.8x+7
0.6x+8.4=0.8x+7
0.2x=1.4
x=7

Answer: engineer need 7pounds of 80% mix

P.s. look at the picture it more easy for understanding!

Find the domain and range of y= f() whose graph is given below.<br> (Click on graph to enlarge)
photoshop1234 [79]

Answer:

-8 <_ x < -3

-7 <_ y < -2

Step-by-step explanation:

closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3

and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)

Answer:

x=-2\\x=2

(You only need to give one solution)

Step-by-step explanation:

We have the following equation

(x^2+1)^2-5x^2-5=0

First, we need to foil out the parenthesis

x^4+2x^2+1-5x^2-5=0

Now we can combine the like terms

x^4-3x^2-4=0

Now, we need to factor this equation.

To factor this, we need to find a set of numbers that add together to get -3 and multiply to give us -4.

The pair of numbers that would do this would be 1 and -4.

This means that our factored form would be

(x^2-4)(x^2+1)=0

As the first binomial is a difference of squares, it can be factored futher into

(x^2+1)(x+2)(x-2)=0

Now, we can get our solutions.

The first binomial will produce two complex (Not real) solutions.

x+2=0\\\\x=-2

x-2=0\\\\x=2

So our solutions to this equation are

x=-2\\x=2
