Answer:

5 divided by (-3)

Step-by-step explanation:

5 3/4 is equals to:

\frac{5*4}{4} + \frac{3}{4} = \frac{23}{4}.

-3 3/8 is equals to:

\frac{-3*8}{8} - \frac{3}{8} = -\frac{27}{8}.

The division of two fractions is the multiplication of the first one divided by the inverse of the second one. So:

\frac{\frac{23}{4}}{-\frac{27}{8}} = -\frac{23}{4}*\frac{8}{27} = \frac{46}{27} = 1.70

As for the answers, we have that:

6 divided by (-3) is -2.

6 divided by (-4) is -1.5.

5 divided by (-3) is -1.67.

5 divided by (-4) is -1.25.

So the best estimation for -1.70 is:

5 divided by (-3)

The value of the solid’s surface area is equal to the value of the solid’s
Katen [24]

Answer:

1. x = 15 in

2. x = 8 m

Step-by-step explanation:

1. Given:

length = 10 in

width = 3 in

height = x in

surface area of the rectangular prism = its volume

Required:

Value of x

Area = 2(wl + hl + hw)

Volume = l*w*h

Therefore:

2(3*10 + x*10 + x*3) = 10*3*x

2(30 + 10x + 3x) = 30x

2(30 + 13x) = 30x

60 + 26x = 30x

Subtract 26x from both sides

60 + 26x - 26x = 30x - 26x

60 = 4x

Divide both sides by 4

60/4 = 4x/4

15 = x

x = 15 in

2. Given:

length = 8 m

width = 4 m

height = x m

surface area of the rectangular prism = its volume

Required:

Value of x

Area = 2(wl + hl + hw)

Volume = l*w*h

Therefore:

2(4*8 + x*8 + x*4) = 8*4*x

2(32 + 8x + 4x) = 32x

2(32 + 12x) = 32x

64 + 24x = 32x

Subtract 24x from both sides

64 + 24x - 24x = 32x - 24x

64 = 8x

Divide both sides by 8

64/8 = 8x/8

8 = x

x = 8 m

Nola Potter earns a salary of $1,200 a month and a commission of 7.5% on all sales over $4,000. This month her sales were $21,40
masya89 [10]

Answer: $5,605

Step-by-step explanation:

Monthly earning = 1200

Commission = 7.5% on sales over 4000

Current month sales = 21400

Total monthly earning :

$4000 + commission on sales over 4000

Total earning for the current month:

$4000 + commission on sales

Commission on current month's sales:

7.5% of 21400

0.075 × $21,400

= $1605

Total amount earned :

$4000 + $1605 = $5,605

Verify -tan^2x+sec^2x?
Mademuasel [1]
We\ know:\\\\\tan x=\dfrac{\sin x}{\cos x}\\\\\sec x=\dfrac{1}{\cos x}\\\\\sin^2x+\cos^2x=1\to \cos^2x=1-\sin^2x\\-----------------------\\\\-\tan^2x+\sec^2x=-\dfrac{\sin^2x}{\cos^2x}+\dfrac{1}{\cos^2x}=\dfrac{-\sin^2x+1}{\cos^2x}=\dfrac{-(1-\sin^2x)}{\cos^2x}\\\\=\dfrac{-\cos^2x}{\cos^2x}=-1
