1/2 mile in 1/26 hour

aleksandr82 [10.1K]

Answer:

1 hour = 13 miles

Step-by-step explanation:

For every 1/26 hours, you travel 1/2 miles

How many miles will you travel in 1 hour?

Well, let's find out!:

1/26 hours = 1/2 miles

1 hour = 1/2 ÷ 1/26

1 hour = 1/2 • 26

1 hour = 13

For every hour, you travel 13 miles :)

Hope this solves your question! :)

Which of the following trigonometric inequalities has no solution over the interval 0 ≤ x ≤ 2pi radians?

valentinak56 [21]

Answer:

A .cos(x)<1

Step-by-step explanation:

According to the first inequality

cos(x)<1

x < arccos 1

x<0

This therefore does not have a solution within the range 0 ≤ x ≤ 2pi

x cannot be leas than 0. According to the range not value, 0≤x which is equivalent to x≥0. Thus means otvis either x = 0 or x> 0.

For the second option

.cos(x/2)<1

x/2< arccos1

x/2<0

x<0

This inequality also has solution within the range 0 ≤ x ≤ 2pi since 0 falls within the range of values.

For the inequality csc(x)<1

1/sin(x) < 1

1< sin(x)

sinx>1

x>arcsin1

x>90°

x>π/2

This inequality also has solution within the range 0 ≤ x ≤ 2pi since π/2 falls within the range of values

For the inequality csc(x/2)<1

1/sin(x/2) < 1

1< sin(x/2)

sin(x/2)> 1

x/2 > arcsin1

X/2 > 90°

x>180°

x>π

This value of x also has a solution within the range.

Therefore option A is the only inequality that does not have a solution with the range.

katie is going to purchase a table for 255 a rug for 158 and 4 chairs for 97 each how much money will she spend all together

wlad13 [49]

$255 for table
$158 for rug
$97 per chair

First find the amount for 4 chairs.

97 × 4 = 388
$388 for 4 chairs

Add:-

255 + 158 + 388
413 + 368
781
$781

Katie will spend $781 all together.
