Find the degree measure of each angle in the triangle

Mathematics
1 answer:
Karo-lina-s [1.5K]3 years ago
4 0

Answer:

∠L = 43°

∠M = 121°

∠N = 16°

Step-by-step explanation:

<u>Start by setting all sides equal to 180</u>

3x - 5 + 7x + 9 + x = 180

<u>Add like terms</u>

11x + 4 = 180

<u>Solve for x</u>

11x + 4 = 180

      - 4     - 4

      11x = 176

     / 11     /11

        x = 16

<u>Now, plug in 16 for all instances of x on the triangle and solve.</u>

∠L = 43°

∠M = 121°

∠N = 16°

The edge of each cube used to build this rectangular prism is 13
kolbaska11 [484]

Answer:

\frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3

====================================================

Step-by-step explanation:

The question is missing the attached figure.

The edge of each cube used to build this rectangular prism is 1/3 inch long. Based on the attached figure.

the volume of the prism = length × height × width

length = 3 * \frac{1}{3} = \frac{3}{3}

height = 3 * \frac{1}{3} = \frac{3}{3}

width = 2 * \frac{1}{3}= \frac{2}{3}

So the volume of the prism = \frac{3}{3} *\frac{3}{3} *\frac{2}{3} =\frac{2}{3} \  in^{3}

∴ The equation that shows the volume of the prism, in cubic inches

= \frac{3}{3} * \frac{2}{3} *\frac{3}{3} =\frac{2}{3} \ in^3

I need the answer to 7 please
bija089 [108]

7. a

Given,

Diameter = 16 feet

So, radius = 16 feet/2 = 8 feet

Circumference = 2πr

So, circumference of this circle

= 2πr

= 2 × 3.14 × 8 feet

= 3.14 × 16 feet

= 50.24 feet

b.

Given,

Diameter = 16 feet

So, radius = 16 feet/2 = 8 feet

Area = πr²

So, area of this circle

= 3.14 × (8 feet)²

= 3.14 × 64 feet²

= 200.96 feet²

ATM personal identification number (PIN) codes typically consist of four-digit sequences of numbers. Find the probability that i
oksian1 [2.3K]

Answer:

(a) 0.0001 or 0.01%

(b) 0.01 or 1%

Step-by-step explanation:

Since there are 10 possible numeric digits (from 0 to 9), and there is only one correct digit, there is a 1 in 10 change of getting each digit right.

The probability that if you forget your PIN, then you can guess the correct sequence

(a) at random:

P=(\frac{1}{10})^4=0.0001=0.01\%

(b) when you recall the first two digits.

P=(\frac{1}{10})^2=0.01=1\%

The diagram shows a circular pond, of radius r metres, surrounded by a circular path.The circular path has a constant width of 1
Alenkasestr [34]

The formula for calculating the area of a circle is expressed as;

A = πr²

  • Area of the pond = πr²
  • Area of the path = Area of the path + pond - area of pond
  • Area of path = π(r+1.5)² - πr²

Since the  area of the path is equal to the area of the pond, hence;

π(r+1.5)² - πr² = πr²

Add πr² to both sides

π(r+1.5)² - πr² + πr² =  πr² + πr²

π(r+1.5)² = 2πr²

(r+1.5)² =   2r²

Expand the parenthesis

r²+3r + 2.25 = 2r²

r²+3r + 2.25 - 2r² = 0

-r² + 3r + 2.25 = 0

r² - 3r - 2.25 = 0

Multiply through by 2

2r² - 6.0r - 4.5 = 0

<em>This proves the required equation</em>
