Given:

[tex]\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]

To find:

The missing value.

Solution:

Let x be the missing value.

We have,

[tex]\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}[/tex]

[tex]\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}[/tex]

Subtract [tex]\dfrac{9}{10}[/tex] from both sides.

[tex]\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{15-9}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{6}{10}[/tex]

[tex]\dfrac{x}{5}=\dfrac{3}{5}[/tex]

Multiplying both sides by 5, we get

[tex]x=3[/tex]

So, the missing value is 3.

Therefore, the correct option is C.

Sell price = purchase price x Mark up

Sell price = 140 x 220%

Sell price = 140 x 2.2 = 308

Sell price = $308

Answer:

Total weight = 1,500 tons

Step-by-step explanation:

Given:

l = 5 ft

b = 5 ft

h = 6 ft

One cubic foot weighed = 0.1 tons

Find:

Total weight

Computation:

Volume = lbh

Volume = (5)(5)(6)

Volume = 150 ft³

Total weight = Volume / 0.1

Total weight = 150 / 0.1

Total weight = 1,500 tons

Answer:  [tex]\frac{8x^3}{27y^6}[/tex]

This is the fraction 8x^3 all over 27y^6

On a keyboard, we can write it as (8x^3)/(27y^6)

===========================================================

Explanation:

The exponent tells you how many copies of the base to multiply with itself.

We'll have three copies of [tex]\left(\frac{2x}{3y^2}\right)[/tex] multiplied with itself due to the cube exponent on the outside.

So,

[tex]\left(\frac{2x}{3y^2}\right)^3 = \left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)*\left(\frac{2x}{3y^2}\right)\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2x*2x*2x}{(3y^2)*(3y^2)*(3y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{(2*2*2)*(x*x*x)}{(3*3*3)*(y^2*y^2*y^2)}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{9y^6}\\\\[/tex]

-------------------

Or another approach you could take is to cube each component of the fraction. The rule I'm referring to is [tex]\left(\frac{a}{b}\right)^c = \frac{a^c}{b^c}[/tex]

Applying that rule will lead to:

[tex]\left(\frac{2x}{3y^2}\right)^3 = \frac{(2x)^3}{(3y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{2^3*x^3}{3^3*(y^2)^3}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^{2*3}}\\\\\left(\frac{2x}{3y^2}\right)^3 = \frac{8x^3}{27y^6}\\\\[/tex]

Either way you should get 8x^3 all over 27y^6 as one fraction.

Answer:

249x + 1y = 250

Step-by-step explanation:

Answer:

5x + 2y = 250 pencils

Step-by-step explanation:

5 represents the amount in each small box.

2 represents the amount in each large box.

Therefore once you multiply by 5 and x, then multiply by 2 and y you should get the total amount of pencils for the pencils in small boxes and the amount for large sepretally. Then you'd add both of the digits to get the total pencils in all

Answer:

14. -g + 10, 15. 12k + 3

Step-by-step explanation:

I'm assuming you want to simplify the equation. For 14, we distribute -2. This gets us -2g + 10 + g. We can simplify that to -g + 10. We can't simplify that, so our answer is complete. For 15, we combine 8k and 4k to get 12k + 3. That can't be simplified, so we are done.

Answer:

103.125

Step-by-step explanation:

110.00 times 15% = 16.5

16.5 times 6.25% = 103.125

Answer - 103.125

Answer:

With the coupon and sales tax, the bicycle costs $100.38.

Step-by-step explanation:

First, we need to find 6.25% of $110.

110 x 0.0625 = 6.88

Now, let's add this to the total, or $110.

110 + 6.88 = $116.88

After that, we need to find 15% of this total.

116.88 x 0.15 = 17.53

Now, we need to subtract this from the total, which is now $116.88.

116.88 - 16.5 = $100.38

Now, with the coupon and sales tax, the bicycle costs $100.38.

Hope this helps! :D

Answer:

B

Step-by-step explanation:

Answer:

Option (4)

Step-by-step explanation:

From the graph attached,

A, B and C are the points based at the heights and valleys of the given curve.

y-coordinates of these points always decide, whether the point is a local maxima or local minima.

y-coordinate of A → -4

y-coordinate of B → 0

y-coordinate of C → -4

Ends of the curve are moving towards infinity, so the absolute maximum is not defined.

Local minimum → -4

Local maximum → 0

Therefore, point representing local maximum is B(0, 0).

Points representing local minimum are A(-2, -4) and C(2, -4).

Option (4) will be the correct option.

Answer:

[H^+] = Antilog[-6]

Step-by-step explanation:

Even though the question is incomplete, let us try to correctly derive the equation used to find the hydrogen ion concentration.

pH=−log[logH^+]

-pH = log[H^+]

[H^+] = Antilog[-pH]

Since pH =6

The equation is;

[H^+] = Antilog[-6]

Answer:

logH=−6

Step-by-step explanation:

Substituting the given value into the formula: 6=−logH; −6=logH; 10−6=H; H=0.000001. The equation logH=−6 is a step in the process of finding the H value.

Answer:

[tex]m = - \frac{3}{5}[/tex]

Step-by-step explanation:

The slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).

The slope of the line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two points on a line—Point 1 and Point 2.

Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

Given,

The line passes through the points (-3,1) and (2,-2)

We have,

x₁ = -3, y₁ = 1

x₂ = 2, y₂ = -2

∵ Slope m = (y₂ - y₁)/(x₂ -x₁  )

Substitute the above values in the formula, and we get

The slope of the line = (-2 - 1) / (2 - (-3))

The slope of the line = (-2 - 1) / (2 +3)

The slope of the line = -3/5

Thus, the slope of the line is -3/5 which line passes through points (-3,1) and (2,-2).

Answer:

p= −x^3−x^2c+4x−3/x−3

c= p/x− 3p/x^2 +x +4/x−3/x^2

Step-by-step explanation:

I hope this helps!!! I have no idea what you were trying to find so I put the value of p and c so I hope this helps you :)

Answer:

c=4

Step-by-step explanation:

Find the value of c so that the polynomial p(x) is divisible by (x−3)

p(x)=−x^3+cx^2 −4x+3

if p is p(3)=-(3)^3 +c(3)^2 -4(3) +3

simplify p(3)= -27+9c -12 +3

combine p(3)=-36+9c

get c alone -9c=-36

divide c=4

Answer:

The ship arrived at 5 am on Saturday

Step-by-step explanation:

Here, we want to know at what time and day the ship arrive the second port

we simply need to add the time it left the first port and the amount of time the journey took

Mathematically, that will be;

22:45 + 7 1/4

1/4 is same as 60/4 = 15 minutes

So we have;

22:45 + 7:15

= 5 am on Saturday
