Answer:

1 2/3

Step-by-step explanation:

x-5x+5=2x-3x

-4x+5= -1x

5=3x

5/3=x

1 2/3=x

-18x

you first times the numbers, which becomes -18

Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)

Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)

-18x

Answer: Select the first one

Step-by-step explanation:

-6 multiplied 3 is -18

AND they both have power x which means  -6x⁸   multiply 3x ⁻⁷

                                                         =  -18 x⁸ ⁺⁽⁻⁷ ⁾(As the have same variable )

                                                         =  -18 x⁸⁻⁷

                                                           =-18 x

Step-by-step explanation:

1 2/3, 1 1/2, 1 1/4 1 7/12 =>

1 8/12 , 1 6/12, 1 3/12, 1 7/12

Answer:

"Certain" Maby I dont know

Answer:

1.37 x 10^-9 F

Step-by-step explanation:

(8.85 x 10^-12) * (0.155) = 1.37 E -12

1.37 E -12 / 0.00100 = 1.37 x 10^-9

Answer:

The right solution is "$1,920,000".

Step-by-step explanation:

Given:

Project cost,

= $1200000

Dr. Leonard sells by

= 60%,

The mark up value will be:

= [tex]\frac{1200000\times 60}{100}[/tex]

= [tex]720,000[/tex] ($)

hence,

The selling price he should put with the bank will be:

= [tex]Project \ cost+Mark \ up \ value[/tex]

= [tex]1200000+720000[/tex]

= [tex]1,920,000[/tex] ($)

Answer:

Step-by-step explanation:

C)   Sarah is trying to say that 72 and 64 are opposite, if 68 is used as the starting point.  So from the point 68,   72 is +4 and 64 is -4.   68 is the "baseline"   or starting point

Answer:

a^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse

90^2 + 120^2 = c^2

8100 + 14400 = c^2

22500 = c^2.....take the sq rt of both sides...this gets rid of the ^2

sq rt 22500 = c

150 = c

so side a = 90 ft, side b = 120 ft, and side c = 150 ft

this is called the pythagorean theorem and it only works on right triangles

done sorry if im wrong

Answer:

i would just round 0.50 to the nearest tenth

Step-by-step explanation:

Now if the lemonade is 1.50 he can only buy two because the total amount is 8.30 so it will be 3.00 and the amount left will be 5.00 and you can only buy one cupcake so you will buy two lemonades one cupcake

Answer:

3

Step-by-step explanation:

You spend $8.30 total. Subtract the $5 for the cupcakes, and you're left with $3.30 to spend on lemonade.

Since you bought the dozen cupcakes, you get the lower price for the lemonade. Lemonade was $1.25, but subtract $0.15 and it's now $1.10/quart

3.30 divided by 1.10 = 3

Answer:

Add those 3 numbers together, it's been awhile since I've done this but you have all 3 numbers so now you add them together

Answer:

SA = 2πr² + 2πrh

Step-by-step explanation:

2πr² will provide the surface area of the top and bottom of the cylinder

2πrh will provide the surface area of the cylinder portion that connects the top and bottom

Answer:

x = -2/15.

Step-by-step explanation:

Finding the second derivative:

f'(x) = 15x^2 +4x - 3

f"(x) = 30x + 4

30x + 4 = 0   for a point of inflection

x = -4/30 =  -2/15

So 30x + 4 is negative up to x =  -2/15 and positive thereafter.

So the curve passes from concave downward to concave upward at x = -2/15.

Answer:

[tex] \displaystyle \left( - \frac{2}{15} , \frac{286}{675} \right)[/tex]

Step-by-step explanation:

to figure out the infection point

take derivative both sides:

[tex] \displaystyle f'(x) = \frac{d}{dx} {5x}^{3} + 2 {x}^{2} - 3x[/tex]

By sum derivation rule we acquire:

[tex] \displaystyle \rm f'(x) = \frac{d}{dx} {5x}^{3} + \frac{d}{dx} 2 {x}^{2} - \frac{d}{dx} 3x[/tex]

apply exponent derivation rule which yields:

[tex] \displaystyle f'(x) = {15x}^{2} + 4{x}^{} - 3[/tex]

take derivative in both sides once again which yields:

[tex] \rm\displaystyle f''(x) = \frac{d}{dx} {15x}^{2} + \frac{d}{dx} 4{x}^{} - \frac{d}{dx} 3[/tex]

remember that, derivative of a constant is always 0 so,

[tex] \rm\displaystyle f''(x) = \frac{d}{dx} {15x}^{2} + \frac{d}{dx} 4{x}^{} - 0[/tex]

by exponent derivation rule we acquire:

[tex] \rm\displaystyle f''(x) = {30x} + 4{}^{} [/tex]

substitute f''(x) to 0 figure out the x coordinate of the inflection point:

[tex] \rm\displaystyle {30x} + 4{}^{} = 0[/tex]

cancel 4 from both sides:

[tex] \rm\displaystyle {30x} = - 4[/tex]

divide both sides by 30:

[tex] \rm\displaystyle {x} = - \frac{2}{15} [/tex]

now plugin the value of x to the given function to figure out the y coordinate of the inflection point:

[tex] \rm \displaystyle f(x) = {5 \left( - \frac{2}{15} \right) }^{3} + 2 {\left( - \frac{2}{15} \right) }^{2} - 3 \left( - \frac{2}{15} \right)[/tex]

By simplifying we acquire:

[tex] \displaystyle f(x) = \frac{286}{675} [/tex]

hence,

the coordinates of inflection point are

[tex] \displaystyle \left( - \frac{2}{15} , \frac{286}{675} \right)[/tex]

Answer:

Step-by-step explanation:

70+85+150+x=360 degree(sum of 4 angles is always 360 degree)

305+x=360

x=360-305

x=55 degree

Answer:

85+1 50+70+x=360{ sum of interior angels of of quadrilateral}

305+x=360

x=360-305

x=55degree

Answer:

Step-by-step explanation:

x+y = 6

y = (6-x)

7x +12y = 52

7x+12(6-x) = 52

7x +72 -12x = 52

-5x = -20

x= 4     4 days at $7  = $28

           2 days at $12 = $24

 28+24 = 52
