I believe the answer is .09625 hours

Explanation: first you do 2.2 x 105= 231
Then you do 231/40=5.775 to get how many minutes it takes to type 231 words. Then u divide 5.775/60 to get how many hours it would take.

ABCD is a parallelogram. Determine the measure of ZB.<br> A) 78°<br> B) 52°<br> C) 39°<br> D) 96°
vovikov84 [41]

\huge\fbox{Answer ☘}

☆ given that ,

ABCD is a parallelogram

☆ we know that ,

opposite angles of a parallelogram are equal.

Therefore ,

\bold\blue{∠B \:= \:∠D}

\pink{3x = x + 52} \\ \pink{3x - x = 52 }\\\pink{ 2x = 52 }\\\pink{ x =  \frac{52}{2}}  \\ \\ \bold\blue{x = 26}

therefore , ∠B = 3x = 3 ( 26° ) = 78°

\fbox{∠B \: = \: 78°}

thus option ( A ) is correct ~

hope helpful~

Finger [1]

Answer:

1)4.51×10^-3

2) .00632

Step-by-step explanation:

1.Which of the following is equivalent to 0.00451?

= \frac{451}{100000}

=\frac{4.51}{1000}

=\frac{4.51}{10^3}

= 4.51×10^-3

Therefore the answer is (a)

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

Which of the following is equivalent to 6.32 x 10-*3?

In order to find the answer to this question you can just put the notation into standard form which means they will be equivalent to each other.

The exponent is negative so you move to the left:

6.32=.00632

=.00632

Therefore 6.32*10^-3 is equivalent too (c) .00632
