Answer:

Krutika

Step-by-step explanation:

Lets convert each person's typing rate to words/min.

Krutika:

80 minutes = 6000 words

1 minute = (6000/80) words

= 75 words

Typing Rate: 75 words / min

Mark:

60 minutes = 4200 words

1 minute = (4200/60) words

= 70 words

Typing Rate: 70 words / min

David:

90 minutes = 5850 words

1 minute = (5850/90) words

= 65 words

Typing Rate: 65 words / min

From the above, we can see Krutika has the fastest rate of words per minute.

the measure of the seven angles in a nonagon measure 138, 154, 145, 132, 128, 147 and 130. if the two remaining angles are equal

mars1129 [50]

A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143

What is the area of the shaded region?

saveliy_v [14]

Answer:

Answer is 330

Step-by-step explanation:

$area \: of \: shaded \: region \: = \pi {r}^{2} - \pi( {x}^{2} \\ here \: r = 11 \: cm \: and \: x = 4 \: cm \\ area \: of \: a \\ shaded \: regoin \: = \pi( {r}^{2} - {x}^{2} ) \\ = \pi( {11}^{2} - {4}^{2} ) \\ = \pi(121 - 16) \\ = \pi(105) \\ = \frac{22}{7} \times 105 \\ = 22 \times 15 \\ = 330 \: {cm}^{2}$

AREA OF SHADED REGION =330

Which of the following is a Recursive Formula for an Arithmetic Sequence?

In-s [12.5K]

The Recursive formula for an Arithmetic Sequence is a1 = -3, an = an-1 + 6.

<h3>What is Arithmetic sequence ?</h3>

An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.

Given:

an = -3 + 6(n – 1)

a1= -3

a2= 3

a3 = 9

Here the common difference is 6 and first term is -3

Hence, the recursive formula is a1 = -3, an = an-1 + 6.

Eliana is reading a 934 page book. She reads 16 pages per day in the book. If x represents the number of days Eliana has spent r

Aleks [24]

On the first day she wen from 934 - 16 pages. Then everyday after that means it would x - 16 pages = PL (PL = Pages Left) so the answer is x - 16 = PL

Students on the CARE Team are selling puppies, yes, puppies! They earn $0.40 on each puppy they sell. Their goal is to earn more

cricket20 [7]

0.4 x >= 327 Divide by 0.4
x >= 327/0.4 which is not going to be an even number.
x >= 817. 5 puppies. So they need to sell 0.5 more puppies. Better round this quickly before someone decides to do something stupid to get the extra 1/2 puppy. For us it's simple. Just add a 1/2 puppy more.

x >= 818 puppies <<<<==== answer.
