Answer:

The remaining area of the circle is 196.06 cm².

Step-by-step explanation:

(area of circle) - (area of triangle) = remaining area of the circle

πr² - ½bh

3.14(8)² - ½(3)(4)

3.14(64) - ½(12)

202.06 - 6

= 196.06

Answer:

195.06 cm²

Step-by-step explanation:

First let's find the area of the circle

[tex]\pi r^{2}[/tex]

[tex]\pi *8*8[/tex]

[tex]64\pi[/tex]

= 201.06 cm²

Now let's find the area of the triangle

[tex]\frac{1}{2} *base*height[/tex]

[tex]\frac{1}{2} *3*4[/tex]

= 6 cm²

Now let's find the area of the shaded region

[tex]201.06-6=195.06\: cm^{2}[/tex]

Hope this helps you.

The temperature in Grand Junction was 73° warmer then Breckenridge that morning. I know this because I started off thinking about how I could get from -28 to 45. I then decided to subtract -28 from 45. This left me with 73°, which is the change in temperature.

Answer:

LCD = 8

Equivalent Fractions with the LCD

3/8 = 3/8

1/2 = 4/8

Solution:

Rewriting input as fractions if necessary:

3/8, 1/2

For the denominators (8, 2) the least common multiple (LCM) is 8.

Therefore, the least common denominator (LCD) is 8.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

3/8 = 3/8 × 1/1 = 3/8

1/2 = 1/2 × 4/4 = 4/8

The least common denominator (LCD) is; 8.

A fraction represents a part of a number or any number of equal parts.

WE need Equivalent Fractions with the LCD;

Now Rewriting input as fractions if necessary:

3/8, 1/2

For the denominators (8, 2) the least common multiple (LCM) would be; 8.

Therefore, the least common denominator (LCD) is; 8.

To Calculate the original inputs as equivalent fractions with the LCD:

3/8 = 3/8 × 1/1 = 3/8

1/2 = 1/2 × 4/4 = 4/8

Answer:

y = -x-4

y+4 = -1(x-0)

Step-by-step explanation:

since its perpendicular to y = x - 2 its slope would be -1 because you have to find the negative reciprocal of 1

then you would just plug every thing into the point slope formula which would look like this

[tex]y + 4 = - 1(x - 0)[/tex]

then to find it in slope intercept form you would do

[tex]y + 4 = - x[/tex]

[tex]y = - x - 4[/tex]

im bo.red so there ya go

Answer:

52 degrees.

Step-by-step explanation:

You can see it is going up 5 and right 10. The slope would be 5/10 (or 1/2).

Since we need to go left 100 units because the x-intercept is (100,0), we will need to repeat the down 5 left 10, 10 times.

-5*10/-10*10 = -50/-100. We will go down -50 times and left -100 which would hit the y-axis. The y-intercept would be -50.

f(x) or y = 1/2x - 50

Double check your work.

y = 1/2 (100) - 50

y = 50 - 50

y = 0 √

  $50,000 in stocks

  $40,000 in bonds

  $25,000 in CDs

Step-by-step explanation:

Let c represent the amount invested in CDs. Then the amount invested in bonds is (c+15000) and the amount invested in stocks is (115000 -c -(c+15000)) = (100000 -2c). The total interest earned is ...

  0.04c +0.053(c +15000) +0.062(100,000 -2c) = 6220

  -0.031c +795 +6200 = 6220

Answer:

820 centimeter :3

Step-by-step explanation:

8.2 meters

move the decimal back twice because of KiloHecaDecaBase (m,l,g)DeciCentiMilli

As we know 1 meter is equal to 100 centimeters so the height of the tree 8.2 meters is equal to 820 meters

The same attribute is expressed using a unit conversion but in a different unit of measurement.

For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.

A conversion factor is a mathematical equation that facilitates an equal exchange of feet for chains.

Given, The height of a tree is 8.2 meters, now we know 1 meter is equal to 100cm so to convert some quantity from meters to centimeters we multiply by 100.

∴ 8.2 meters is equal to (8.2×100) = 820 centimeters.

is m, given by the slope formula below:

[tex] m = \dfrac{y_1 - y_2}{x_2 - x_1} [/tex]

2) a. (30, 32) and (18, 16)

[tex] m = \dfrac{y_1 - y_2}{x_2 - x_1} [/tex]
