What is the missing value?

Answer: [tex]6, 9\ \text{units}[/tex]

Step-by-step explanation:

Given

The Sum of length and width is [tex]15\ units[/tex]

length is 3 units more than the width

width is [tex]x[/tex]

length is [tex]x+3[/tex]

Their sum is 15

[tex]\Rightarrow x+x+3=15\\\Rightarrow 2x=12\\\Rightarrow x=6\ \text{units}[/tex]

Length is [tex]x+3=9\ \text{units}[/tex]

Width is  [tex]x=6\ \text{units}[/tex]

You calculate wall-length like this.

Measure the length of each wall including doors and windows. Find the total square feet of the wall(s) by multiplying ceiling height by total wall length. Subtract areas that will not be covered.

Answer:log1/25=-2.32193

Step-by-step explanation:

Given : Expression log1/25

To find : The solution of the given expression?

Solution:

We have given expression log1/25

If you want me to show my work tell me but it is a long process so yeh but the answer is -2.32193.

Answer:

-2.32193

Step-by-step explanation:

Applying logarithmic property:

[tex]log_ba=\frac{log_ea}{log_eb}=\frac{In\;a}{In\;b}[/tex]

Solve:

[tex]log_\frac{1}{2}5=\frac{In(5)}{In\;\frac{1}{2}}[/tex]

[tex]\frac{In(5)}{In\;\frac{1}{2}}=\frac{1.60943}{-0.69315}[/tex]

[tex]\frac{In(5)}{In\frac{1}{2}}=-2.32193[/tex]

Hence, answer = -2.32193

Answer:

Step-by-step explanation:

The average rate of change in the value of the account for the first 3 years is,  $3.15/year. So Option C  is correct.

Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.

So formula for the rate is,

m = change in one quantity/change in another quantity = Δy/Δx

The average rate of change in the value of the account for the first 3 years can be calculated as follows:

Let t = 0 be the time when the account is opened,

and t = 3 be the end of the third year.

The value of the account at t = 0 is V(0) = 30,

and the value of the account at t = 3 is

V(3) = 30(1.05)³

The average rate of change in the value of the account over the first 3 years is given by the formula:

⇒ (V(3) - V(0)) / (3 - 0)

⇒ (30(1.05)³ - 30) / 3

⇒  $3.15/year

Hence, the average rate of change in the value of the account over the first 3 years is approximately $3.15/year

Answer:

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

26 - 26 = 0

180 - 26 = 154

x = 154°

The value of the x will be 154°.

The central angle and the angle between the tangents are supplementary.

If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to line L.

So,

x + 26° = 180°

Subtract 26° from both sides;

x + 26 - 26 =  180 - 26

x = 154°

Hence, the value of the x will be 154°.

Answer: The answer is 26.

Step-by-step explanation:

Simple, find the unit rate. That's 19.5 / 0.75 = 26.

or using fractions:

19 2/4  divided by 3/4

78/4 divided by 3/4

78 / 3 = 26

4 / 4 =    1

Answer:

Number of $1 coins are 25 and number of 50 cent coins are 30.

Step-by-step explanation:

Let's set up the equations.

Let there are x number of $1 coins

There are y number of 50 cent coins

So, x+y =55

1 x+0.50 y =40

Solve the equations for x and y.

Solve the first equation for y.

y=55-x

Substitute y as 55-x into the second equation.

1 x+0.50(55-x)=40

Solve the equation for 'x'.

Distribute the 0.50 to get rid the ( ).

1 x+27.5-0.50 x= 40

Combine like terms

0.50 x +27.5=40

Subtract both sides 27.5

0.50 x =12.5

Divide both sides by 0.50

x=25

Now, plug in x as 25

y=55-25

y=30

So, number of $1 coins are 25 and number of 50 cent coins are 30.

Answer:

24 unit

Step-by-step explanation:

From the question,

JK = 2×NK.................... Equation 1

Using pythagoras theorem,

a² = b²+ c²................. Equation 2

From the diagram,

a = 15 unit, b = 9 unit, and c = NK

Substitute these values into equation 2

15² = 9²+(NK)²

Solve for NK

225 = 81+(NK)²

(NK)² = 225-81

(NK)²  = 144

NK = [tex]\sqrt{144}[/tex]

NK = 12 unit.

Substitute these value of NK into equation 1

JK = 2×12

JK = 24 Unit.

Answer:

the answer is 221.1

Step-by-step explanation:

The volume of the rectangular prism is 221.1 in³.

The volume of any object defined the capacity of it, how much it can hold something is called its volume.

Given is rectangular prism, we need to find the volume of the same,

So, we know that the volume of a rectangular prism is the product of its dimensions.

V = length × width × height.

[tex]V = 16\frac{3}{4} \times 4\frac{2}{5} \times 3[/tex]

[tex]V = \frac{67}{4} \times \frac{22}{5} \times 3[/tex]

V = 4422/20

V = 221.1

Hence, the volume of the rectangular prism is 221.1 in³.
