Why is this not an equilateral triangle?

Answer:

angle 1= 59 degree, angle 2= 61 degree and angle 3 = 119 degree

Step-by-step explanation:

because in the figure angle 2 and 61 degree are alternative angle so they are equal

The exponential equation of the graph is y = 1.59 * 1.26^x

On the graph, we have the following points

(x,y) = (2,1) and (4,4)

An exponential function is represented as;

y = ab^x

So, we have:

ab^1 = 2 and ab^4 = 4

Divide both equations

b^3 = 2

Take the cube root of both sides

b = 1.26

Substitute b = 1.26 in ab^1 = 2

1.26a = 2

Divide both sides by 1.26

a = 1.59

So, we have:

y = ab^x

y = 1.59 * 1.26^x

Hence, the exponential equation of the graph is y = 1.59 * 1.26^x

Answer:

64

Step-by-step explanation:

The information can be written as:

Let Alex's number = x

Winnie's number = y

x = 1.75y

x = y + 48

Substitute 1.75y for x:

1.75y = y +48

0.75 y = 48

3/4 y = 48

y = 64

Step-by-step explanation:

The common difference is 8-5 = 3

The first next term is 11 + 3 = 14

The next (second) term  is 14 + 3 = 17

tn = 5 + (n - 1)*3       This is part c

t20 = 5 + (20 - 1)*3

t20 = 5 + 19*3

t20 = 5 + 57

Answer t20 = 62

Only three are geometric sequences, a which is 3/16, 3/8, 3/4, 3/2, d which is 3,9,27,81 and f which is -4(4/9)^x

A geometric sequence is a sequence of numbers or functions in which successive member differ by a constant term called the common ratio.

Analysis:

For a, the first term is 3/16, second term is 3/8. if we divide the second term by the first we have 2. If we do same with the third and second we still have 2. so this is a geometric sequence

For d, if we divide 9 by 3 we have 3, if we divide 27 by 9 we have 3. so this is a geometric sequence.
For f, if we make x equal to a nonzero integer, we have first term as -16/9, second term as -64/81 and third term as -256/729. if we divide the second term by the first we have -4/9, if we divide the third by the second we have-4/9.

In conclusion, Only three are geometric sequences, a which is 3/16, 3/8, 3/4, 3/2, d which is 3,9,27,81 and f which is -4(4/9)^x

The ratio of the height of shape A to the height of shape C is [tex]\frac{3}{10}[/tex]

Recall that similar figures have the same scale factor squared due to the ratio of its surface area.

Hence,

We would make:

[tex]z^2 = x/y\\z= 2/5[/tex]

Therefore, the ratio of the height of shape A to the height of shape B is = [tex]\frac{hA}{hB} = \frac{2}{5}[/tex]

To find the ratio of the height of shape B to the height of shape C, we would perform a similar operation which is:

[tex]z^3 = 27/64\\z= 3/4[/tex]

The ratio is:

[tex]\frac{hB}{hC} = \frac{3}{4}[/tex]

To find the ratio of the height of shape A to the height of shape C would be:

[tex](\frac{hA}{hB}) (\frac{hB}{hC} )= \frac{hA}{hC}[/tex]

Answer:

$102.75

Step-by-step explanation:

Given the following question:

We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.

Formula to calculate percentages:

[tex]\frac{p\times n}{100}[/tex]

First the disc:

[tex]\frac{10\times 75}{100}[/tex]
[tex]10\times75=750[/tex]
[tex]750\div100=7.5[/tex]
[tex]=7.5[/tex]

Next the tax:

[tex]\frac{7\times75}{100}[/tex]
[tex]7\times75=525[/tex]
[tex]525\div100=5.25[/tex]
[tex]=5.25[/tex]

Last but not least the tip:

[tex]\frac{20\times75}{100}[/tex]
[tex]20\times75=1500[/tex]
[tex]1500\div100=15[/tex]
[tex]=15[/tex]

Finally add:

[tex]75+7.50+5.25+15=102.75[/tex]
[tex]=102.75[/tex]

The total cost after adding the disc, tax, and the tip will be "$102.75."

Answer:Calvin throws 12 sheets of paper up in the air.

He randomly catches one of the sheets as they float down.

Of the 12 sheets of paper, 9 are white and 3 are red.

The probability that Calvin caught a white sheet is = or 75%.

It is likely that this event occurs as above 70% we say that the event is likely and here the probability is 75%.

The probability that Calvin caught a red sheet is = or 25%

This is unlikely to happen. Thus, we can say that it is not likely event.

Return the marble he initially drew from the bag

Step-by-step explanation:

The expression of time in terms of r is T = 85/9r. If he walked at an average speed of 3 miles per hour. Then the time taken by nick to reach the shopping mall will be 3 hours and 60 minutes.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

Nick walked 5 miles to reach his aunt's house.

From there he traveled 8 miles to the shopping mall on a bicycle.

He traveled 80% faster on the bicycle than on foot.

Let r represent his rate of walking in miles per hour. Then the 1.8r will be the rate of cycling in miles per hour.

Then the number of hours nick took to reach the shopping mall in terms of r will be

T = t₁ + t₂

Where t₁ is the time taken to reach his aunt's house and t₂ is the time taken to reach the shopping mall from his aunt's house. Then we have

T = 5 / r + 8 / 1.8r

T = 1/r (5 + 8/1.8)

T = 85/9r

If r is 3 miles per hour, then the time taken by nick to reach the shopping mall will be

T = 85 / (9 x 3)

T = 3.15 hours

T = 3 hours and 9 minutes

Answer:

y = (x+8)(x+3)

Step-by-step explanation:

If you multiply

(x+8)(x+3),

you get x^2 + 3x + 8x + 24

This simplifies to x^2 + 11x + 24, same as the original question.

The graph of y=x² + 11x + 24 is equivalent to the y=(x+8)(x+3).

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Constants and variables are components of a polynomial.

We have Graph whose equation is

y=x² + 11x + 24

Now, factories the above equation using splitting the middle term

y=x² + 11x + 24

y=x² + 8x + 3x + 24

y = x(x+8) + 3(x+8)

y= (x+3)(x+8)
