Answer:

(c)Rhombus

Step-by-step explanation:

A parallelogram is a quadrilateral (has four sides) in which opposite sides are parallel to each other. Also for a parallelogram, the opposite sides and angles are equal to each other.

A rhombus is a parallelogram (that is opposites sides and angles are equal to each other and parallel) with all sides of equal length. The diagonals of a rhombus bisect each other at 90° to form four equal right angled triangles with the sides of the rhombus as the hypotenuse.

Simplify h= 105sin (0.0698(90+1)) + 105
IrinaK [193]

Answer:

h= 116.616

Step-by-step explanation:

we have

h= 105sin (0.0698(90+1)) + 105

step 1

Solve (90+1)

h= 105sin (0.0698(91)) + 105

step 2

Solve 0.0698(91)

h= 105sin (6.3518) + 105

step 3

Solve sin (6.3518)

h= 105(0.11063) + 105

step 4

Solve 105(0.11063)

h= 11.616 + 105

step 5

Solve 11.616 + 105

h= 116.616

Simplify the expression. Write the answer using scientific notation. (7 × 105)2 a. 4.9 × 1010 b. 4.9 × 1011 c. 4.9 × 109 d. 49 ×
nataly862011 [7]

Answer:

b. 4.9 × 1011

Step-by-step explanation:

Using scientific notation is similar to expressing in standard form. Given that (7 × 105)2

We open the parenthesis. This may first be expressed as

7² × 10⁽⁵⁾²

Then expand,

= 49 × 10¹⁰

To put in scientific notation, 49 = 4.9 × 10

Hence the expression becomes

= 4.9 × 10 × 10¹⁰

Using the laws of indices

= 4.9 ×  10¹¹ in scientific notation

Andrew has $2.00 in quarters in his pocket, including three state quarters. He takes two quarters out of his pocket. What is the
Zolol [24]
$2.00 in quarters is 8 quarters, since 1 quarter is 25 cents.
Out of those 8 quarters, only 3 are state quarters.
That means 5 are not state quarters.
So there is a 5/8 chance that the first quarter he takes out is not a state quarter.
If it is not, then there are 3 state quarters and 7 total quarters left, which means a 4/7 chance that the second quarter is not a state quarter.
To find the probability of both of these quarters not being state quarters, multiply the probabilities by each other.
4/7 • 5/8 = 20/56
Now simplify:
20/56 = 10/28 = 5/14
5/14 is in simplest form, so it is the answer.
So the answer is D. 5/14.
