Ms. KC ate 1/2 of 3/4 of a sicilian pie. Did Ms. KC eat more or less than 3/4 of
the pie? Explain.

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].

7 / 10 < 11 / 12

Step-by-step explanation:

cross multiply

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.

Step-by-step explanation:

B only

cos B = a/c

Answer:

2

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.

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

Answer:

So the answer is $3.99 / 12 = $0.3325 per can = 33.25 ¢ per can.

Answer:

[tex]4^{3}[/tex]

Step-by-step explanation:

Its in exponential form already the exponent is 3.

4 × 4 × 4 (standard form)

And then the actual answer will be 64....4 × 4 × 4 = 16 × 4 = 64

Answer:

5. b  6. c  7. d  8. a

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

A. x = 6; v = 42

Step-by-step explanation:

Strategy : Guess and Check

Let's start with A:

If x = 6, then the first rectangle would be 12 + 42 + 6  + 12 + 42 + 6 = 120

Let's see if this checks out with the second rectangle.

6 + 42 + 42 +  6 + 42 + 42 = 180

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]

$68.34 will be paid

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]

Answer:

195.6

Step-by-step explanation:

area of base= 1/2 * 8 * 6.9 = 27.6

area of lateral face= 1/2 * 8 * 14 = 56

total surface area = 27.6 + 56 + 56 + 56 = 195.6

Step-by-step explanation:

hope this helps have a great night❤️❤️❤️❤️

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

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
