In the diagram below, which pair of angles is complementary?

Answer:

Please see the detailed answers below:

Step-by-step explanation:

Solution 1:

Sandwich = $9.25

Salad = $4.35

Tax = 7.5%  

=> ($9.25 + $4.35) x 7.5 / 100 = 13.6 x 0.075 = $1.02

The amount of Tax on Veena's meal is $1.02

Solution 2:

Book read by Christian = (1/4) / (2/3) = (1/4) x (3/2) = 3/8

Christian will read 3/8 books per week.

Solution 3:

Sale Price = (100 - Discount Rate) x Cost Price

Let Y = Sale Price

By Putting the values in above equation:

Y = (100 - 45) x $650

Y = 0.55 x $650

Y = $357.5

Hence the Sale Price of the bicycle will be $357.5

Solution 4:

Percent error = [(Experimental Value - Accepted Value) / Accepted Value] x 100

Percent error = [(15.5 - 14.5) / 14.5] x 100

Percent error = [1 / 14.5] x 100

Percent error = 2.2%

Hence the percent error in Mark's estimate is 2.2%

Answer:

The maximum rate of change is between second 15 and second 19.

Step-by-step explanation:

See the attached table.

The table shows the total distance a spider traveled after a light was turned on.

Now, the average rate of change between two consecutive times in the table is given by  

= [tex]\frac{\textrm {Total change in Distance in feet}}{\textrm {Total change in Time in seconds }}[/tex]

Therefore, between second 5 and second 11, the average rate of change = [tex]\frac{7 - 4}{11 - 5} = 0.5[/tex]

Between second 11 and second 15, the average rate of change = [tex]\frac{13 - 7}{15 - 11} = 1.5[/tex]

Between second 15 and second 19, the average rate of change = [tex]\frac{20 - 13}{19 - 15} = 1.75[/tex]

Between second 19 and second 28, the average rate of change = [tex]\frac{24 - 20}{28 - 19} = 0.44[/tex]

Therefore, the maximum rate of change is between second 15 and second 19. (Answer)

Answer:

[tex]x=-2\sqrt5\ and\ x=2\sqrt5[/tex]

Step-by-step explanation:

Given:

The given equation to solve is:

[tex]x^2=20[/tex]

In order to solve the above equation, we take square root on both the sides.

While taking square root on both sides, we must consider both positive and negative values. So, this gives:

[tex]\sqrt{x^2}=\pm\sqrt{20}[/tex]

From the definition of square root function, we have

[tex]\sqrt{a^2}=a[/tex]

Therefore,

[tex]x=\pm\sqrt{20}[/tex]

Now, writing 20 into the product of its prime factors, we have

[tex]20=2^2\times 5[/tex]

Therefore, [tex]x=\pm\sqrt{2^2\times 5}[/tex]

We also know, [tex]\sqrt{a\times b}=\sqrt{a}\times\sqrt{b}[/tex]

So, [tex]\sqrt{2^2\times 5}=\sqrt{2^2}\times \sqrt{5}=2\sqrt5[/tex]

Therefore, [tex]x=\pm2\sqrt5[/tex]

So, there are two values of 'x'. They are:

[tex]x=-2\sqrt5\ and\ x=2\sqrt5[/tex]

Answer:

x = 3

Answer: 138

Step-by-step explanation:

Let the first number be x , the second number be x + 2 and the third number be x + 4 since they are consecutive even numbers.

Their sum implies:

x + x + 2 + x + 4 = 408

3x + 6 = 408

subtract 6 from both sides

3x + 6 - 6 = 408 - 6

3x = 402

divide through by 3

3x/3 = 402/3

Therefore x = 134.

The numbers are :

134 , 136 and 138 , this means that the largest number is 138

Answer:

g(x) = - (x² + 3x + 2) = - x² - 3x - 2

Step-by-step explanation:

The graph represents the function f(x) = x² + 3x + 2.

Now, g(x) is the function which is obtained by reflecting f(x) across the x-axis.

While a graph of a function reflects across x-axis then its y-values will change sign for a fixed value of x.  

Therefore, the function g(x) will be given by  

g(x) = - (x² + 3x + 2) = - x² - 3x - 2 (Answer)

In this question, we're trying to make an equation for the given scenario and answer a couple of leading questions.

We know that Aiko types at a rate of 70 words per minute

We would represent this as 70x

x = minutes

We are also given more information that he types 210 words in 3 minutes, that still follows our "70x" scenario.

So our equation would be:

y = 70x

The slope of the linear equation would be 70 or 70/1

The slope would be 70 because this is the change that's happening each minute.

A point on a graph would be at (1 , 70)

You would put this equation into a graph, and you would grab a point that's on the linear line. I'll insert a picture of the graph

The linear equation would be written as: y = 70x

The beginning point would be at 0, since Aiko doesn't type anything for 0 minutes.

Answer:

1 The slope of the linear equation is  70

2 One point on the graph of a linear equation will be 3, 210

3,This linear equation can be written as  y-210=70(x-3)

Answer:

[tex]Rs\ 4,296[/tex]

Step-by-step explanation:

step 1

Find out the lateral area of the pillars

we know that

The lateral area of a rectangular prism is equal to

[tex]LA=PH[/tex]

where

P is the perimeter of the base

H is the height of the prism

Determine the perimeter of the base

[tex]P=4(1)=4\ ft[/tex] ----> is a square base

[tex]H=6\ ft[/tex]

The lateral area is equal to

[tex]LA=4(6)=24\ ft^2[/tex]

Remember that the number of pillars is 2

so

[tex]LA=2(24)=48\ ft^2[/tex]

step 2

Find the cost of tiling the pillars at the rate of  Rs 52 per square feet

Multiply the lateral area of the two pillars by the rate

so

[tex]48(52)=Rs\ 4,296[/tex]

Answer:

The value of log  43is 1.633

Step-by-step explanation:

Explanation:

Suppose you know that:

[tex]\begin{array}{l}{\log 2 \approx 0.30103} \\{\log 3 \approx 0.47712}\end{array}[/tex]

Then note that:

[tex]43=\frac{129}{3} \approx \frac{128}{3}=\frac{2^{7}}{3}[/tex]

So

[tex]\log 43 \approx \log \left(\frac{2^{7}}{3}\right)=7 \log 2-\log 3 \approx 7 \cdot 0.30103-0.47712=1.63009[/tex]

We know that the error is approximately:

[tex]\log \left(\frac{129}{128}\right)=\log 1.0078125=\frac{\ln 1.0078125}{\ln 10} \approx 0.00782 .3=0.0034[/tex]

So we can confidently give the approximation:

Please see pic

Step-by-step explanation:

Go two places to the right (on x axis), then four places down (on y axis)

Sorry it would not let me attach a pic

It would have a greater slope and perhaps start higher on the y axis.

Step-by-step explanation:

I assume you can choose your own numbers as long as they are higher than the current. This means the numbers on your y axis will change but not the numbers on your x axis because that determines the time. So let's change the y axis numbers from going by 20 and make them go by 25. You could technically keep the dots in the same place as long as you change the y axis numbers because you are still earning more money.

Skippy should invest $ 7500 in account offering 4 % interest and $ 2500 in account offering 8 % simple interest

Solution:

Given that Skippy has a total of $10,000 to split between two investments

One account offers 4% simple interest, and the other account offers 8% simple interest

Total interest earned = 500

Number of years = 1

Let the principal with rate of interest 4 % is x

So the principal for rate of interest 8 % is 10000 - x

Total interest earned = simple interest for 4 % interest + simple interest for 8 % interest

Simple interest is given as:

[tex]S.I = \frac{pnr}{100}[/tex]

Where "p" is the principal and "r" is the rate of interest and "n" is the number of years

Therefore,

[tex]\text{ Total interest earned } = \frac{x \times 1 \times 4}{100} + \frac{10000-x \times 1 \times 8}{100}[/tex]

[tex]500 = 0.04x + (10000 - x)0.08\\\\500 = 0.04x + 800 - 0.08x\\\\-300 = -0.04x\\\\x = 7500[/tex]

Therefore skippy should invest $ 7500 in account offering 4 % interest

And skippy should invest (10000 - x) = (10000 - 7500) = $ 2500 in account offering 8 % interest

#SPJ2

Answer:

line c

Step-by-step explanation:

Answer: x = 6

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is -3x.

Since 28 is being added to -3x, we subtract 28 from both sides of the equation to isolate the -3x. On the left, the +28 and -28 cancel out and on the right 10 - 28 is -18 so we have -3x = -18.

Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and we have x. On the right, -18 divided by -3 is 6 so we have x = 6 which is the solution to our equation.

Which polynomial is equal to  (-3x^2 + 2x - 3) subtracted from  (x^3 - x^2 + 3x)?

The polynomial equal to (-3x^2 + 2x - 3) subtracted from  (x^3 - x^2 + 3x) is [tex]x^3 + 2x^2 + x + 3[/tex]

Given that two polynomials are: [tex](-3x^2 + 2x - 3)[/tex] and [tex](x^3 - x^2 + 3x)[/tex]

We have to find the result when [tex](-3x^2 + 2x - 3)[/tex] is subtracted from  [tex](x^3 - x^2 + 3x)[/tex]

In basic arithmetic operations,

when "a" is subtracted from "b" , the result is b - a

Similarly,

When [tex](-3x^2 + 2x - 3)[/tex] is subtracted from  [tex](x^3 - x^2 + 3x)[/tex] , the result is:

[tex]\rightarrow (x^3 - x^2 + 3x) - (-3x^2 + 2x - 3)[/tex]

Let us solve the above expression

There are two simple rules to remember:

So the above expression becomes:

[tex]\rightarrow (x^3 - x^2 + 3x) + 3x^2 -2x + 3[/tex]

Removing the brackets we get,

[tex]\rightarrow x^3 - x^2 + 3x + 3x^2 -2x + 3[/tex]

Combining the like terms,

[tex]\rightarrow x^3 -x^2 + 3x^2 + 3x - 2x + 3[/tex]

[tex]\rightarrow x^3 + 2x^2 + x + 3[/tex]

Thus the resulting polynomial is found
