Answer:

9.103

10. 77

11.60

12. 6.4

13. 20

14. 36

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

180 - (47 + 30) = 103

DEG = 180 - 103 = 77 angles on a straight line equals 180

An equilateral triangle has all 3 sides equal

if the sum of angles in a triangle is 180 degrees, each angle measures 180 / 3 = 60

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

5² + 4² = 41

squareroot of 41 = 6.4

b : √(25² - 15²) = 20

√(60² - 48²) = 36

Three cards are dealt from a shuffled standard deck of playing cards. Find the probability that the first card dealt is red, the

harina [27]

There are 52 cards in a deck, half the cards aware red and half the cards are red.

First card being red is 26/52 = 1/2

After the first card is dealt there are 51 cards left and 26 are black so dealing a black card = 26/51

After 2 cards are dealt there are 50 cards left and 25 red ones left. The probability would be 25/50 = 1/2

The probability of all 3 happening = 1/2 x 26/51 x 1/2 = 13/102

Circumference and Area of Circles

yanalaym [24]

Step-by-step explanation:

Area of a circle = #r^2

1256 = 3.14 × r^2

r^2 = 1256/3.14

r^2 = 400

Square root of r = 20

Diameter = 2 × r = 2 × 20 = 40 inches

The model shows the expression 20 + 16. Which expression is equivalent to this sum?

Natali5045456 [20]

Answer:

4(5+4)

Step-by-step explanation:

4(5+4) equals 36, and 20 + 16 equals 36 as well, so therefore 20 + 16 is equivalent to 4(5+4)

Multiply or divide as indicated. x^-8 • x^-2

gladu [14]

ANSWER

$\frac{1}{ {x}^{10} }$

EXPLANATION

The given exponentiial expression is

${x}^{ - 8} \bullet {x}^{ - 2}$

We simplify using the rule:

${a}^{m} \times {a}^{n} = {a}^{m + n}$

We apply this property to get:

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 8 + - 2}$

We simplify to get;

${x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 10}$

We rewrite as a positive index to get;

${x}^{ - 8} \bullet {x}^{ - 2} = \frac{1}{ {x}^{10} }$
