Pythagorean theorem: A^2 + B^2 = C^2

C is the hypotenuse, the side opposite from the 90 degree angle. So we have C and A.

c^2 - a^2 = b^2

23^2 - 16^2 = b^2

b^2 = 273

b= 16.5

Answer:

478.32

Step-by-step explanation:

1) the basic formula is:

[tex]A=A_{base}+A_{sidesurface}.[/tex]

2) the Area of the base consists of 6 triangles, they are the same. In one triangle: its base is 8 cm., the height is 6.93 cm, - then the Area of one triangle is 0.5*8*6.93=27.72 (cm²);

[tex]A_{base}=6*27.72=166.32(cm^2).[/tex]

3) the Area of the side surface consists of 6 triangles, they are the same. In one triangle: its base is 8 cm., the height is 13 cm, - then the Area of one triangle is 0.5*13*8=52 (cm.²);

[tex]A_{sidesurface}=6*52=312(cm.^2).[/tex]

4) finally, the required Area:

[tex]Area=A_{base}+A_{sidesurface}=166.32+312=478.32(cm.^2).[/tex]

A tree measured 12 1/2 feet tall. Over the next 5 1/2 years it grew to be 51 feet tall. During the 5 1/2 years, what was the average yearly growth rate of the tree?

Answers

Answer:

7 feet

Step-by-step explanation:

Let's find how many feet did the tree gain during 5 1/2 years:

51 - 12.5 = 38.5

Now devide this number by 5 1/2 to find average length tree gained yearly:

38,5 / 5.5 = 7

what is the solution to the equation. first to get it is brainlyist

Answers

Answer:

Third from the top, a=

[tex]3 \frac{1}{3} [/tex]

Answer:

a = 3 1/3

Step-by-step explanation:

We first separate the whole numbers from the fractions

So first we do

5 + 3 = 8

Then we add the fractions together

1/3 + 2/3 = 1

Then, we add the sum of the whole numbers and of the fractions

8 + 1 = 9

Thus, a = 3 1/3

what is the slope of negative 2y plus 6 equals 4x

Answers

Answer:

Step-by-step explanation:

The first step is to convert the equation to slope-intercept form (y = mx+b).

2y+6 = 4x

2y+6-6 = 4x-6

2y = 4x-6

2y/2 = 4x/2-6/2

y = 2x-3

In slope-intercept form (y = mx+b), m is the slope. 2 is m in the equation, so therefore it is the slope.

Joseph found the bike he wanted in the clearance section at walmart. It has the price of $88.99, but is in 30% off section. How much will his total be if the sales tax is 9.7%?

Answers

Answer:

[tex]Total = \$68.34[/tex]

Step-by-step explanation:

Given

[tex]Price = \$88.99[/tex]

[tex]Discount = 30\%[/tex]

[tex]Sales\ Tax = 9.7\%[/tex]

Required

Determine the payable amount.

First, calculate the amount after discount

[tex]Amount = Price - Price * Discount[/tex]

[tex]Amount = Price (1 - PDiscount)[/tex]

[tex]Amount = \$88.99(1 - 30\%)[/tex]

[tex]Amount = \$88.99(70\%)[/tex]

[tex]Amount = \$62.293[/tex]

The total after sales tax is:

[tex]Total = Amount (1 + Sales\ Tax)[/tex]

[tex]Total = \$62.293 (1 + 9.7\%)[/tex]

[tex]Total = \$62.293 (1 + 0.097)[/tex]

[tex]Total = \$62.293 (1.097)[/tex]

[tex]Total = \$68.335421[/tex]

[tex]Total = \$68.34[/tex]

The graph of y = 4x2 - 4x – 1 is show
Use the graph to find estimates for
the solutions of
i) 4x2 - 4x – 1 = 0

Answers

Answer:

Here we have the equation:

y = 4*x^2 - 4*x - 1

And we should have the graph (you can see it below this answer)

Now we want to find the solutions of:

4*x^2 - 4*x - 1 = 0

These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.

Then we need to find the two values of x at which our graph intersects the x-axis.

In the graph, we can estimate the solutions as:

x = -0.2

x = 1.2

To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:

[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*4*(-1)} }{2*4} = \frac{4+ -\sqrt{32} }{8} = \frac{4 +-5.66}{8}[/tex]

Then the two solutions are:

x = (4 + 5.66)/8 = 11.2075

x = (4 - 5.66)/8 = -0.2075

using suitable identity find 231^222-131^2

Answers

Given:

Consider the expression is

[tex]231^2-131^2[/tex]

To find:

The value of given expression using a suitable identity.

Solution:

We have,

[tex]231^2-131^2[/tex]

Using the identity [tex]a^2-b^2=(a-b)(a+b)[/tex], we get

[tex]231^2-131^2=(231-131)(231+131)[/tex]

[tex]231^2-131^2=(100)(362)[/tex]

[tex]231^2-131^2=36200[/tex]

Therefore, the value of the given expression is [tex]231^2-131^2=36200[/tex].

Simple interest to find the ending balance $460 at 13% for
2
years

Answers

Answer:

$568.16

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 13%/100 = 0.13 per year,

then, solving our equation

I = 416 × 0.13 × 2 = 108.16

I = $ 108.16

The simple interest accumulated

on a principal of $ 416.00

at a rate of 13% per year

for 2 years is $ 108.16.
