Wezi has sixty-three $5-bills. He takes the $5-bills to the bank to exchange them for $20-bills. How many $20-bills does Wezi get? Is there money left over? Explain.

Answers

Answer: 15

Step-by-step explanation:

From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:

= 63 × $5

= $315

We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:

= $315 / $20

= 15 3/4

Therefore, he will get 15 $20 bills

If you take the problem and divide into two rectangles by drawing the line up from the bottom 4.

You end up with one rectangle that is

and a second thats

4x6.

The area is then calculated by taking the length and multiplying by the width of the first (8 x 4) and adding to the same process of the second (4x6)

Thus

The subject 'x' in terms of 'y'

[tex]x = \sqrt{\frac{y+2}{3} }[/tex]

Step-by-step explanation:

Explanation:-

Given subject in terms of 'x'

 y = 3 x² - 2

Adding '2' on both sides, we get

y + 2 = 3 x² - 2 +2

y+2 =  3 x²

Dividing '3' on both sides, we get

The diagram below models the diameter of the bicycle wheel
21.75
Which of the following is closest to the distance of the length when the bicycle wheel
makes 1 revolution?
A7 inches
B 25 inches
C34 inches
D69 inches


Can anyone help me!!

Answers

Answer: (21.75 / 2) * 2 * pi = 68.42...in, answer D.

Explanation: one revolution from a wheel will be a 360 degree rotation, meaning that if you had laid your finger on the outside of the wheel as it made its full rotation, your finger would have touched the entire circumference of the wheel. Thus, we can represent the length of 1 revolution as the circumference. Thus we take the diameter, and divide it by 2 to get the radius. Then we simply multiply by 2 * pi * r (r = radius). This is the formula for the circumference of a circle.

Above lone woodland ways that led To dells the stealthy twilights tread The west was hot geranium red; And still, and still, Along old lanes the locusts sow With clustered pearls the Maytimes know, Deep in the crimson afterglow, We heard the homeward cattle low, And then the far-off, far-off woe Of "whippoorwill!" of "whippoorwill!"II. Beneath the idle beechen boughs We heard the far bells of the cows Come slowly jangling towards the house; And still, and still, Beyond the light that would not die Out of the scarlet-haunted sky; Beyond the evening-star's white eye Of glittering chalcedony, Drained out of dusk the plaintive cry Of "whippoorwill," of "whippoorwill."III. And in the city oft, when swims The pale moon o'er the smoke that dims Its disc, I dream of wildwood limbs; And still, and still, I seem to hear, where shadows grope Mid ferns and flowers that dewdrops rope, Lost in faint deeps of heliotrope Above the clover-sweetened slope, Retreat, despairing, past all hope, The whippoorwill, the whippoorwill.Whippoorwill - a nocturnal bird with a distinctive call that is suggestive of its nameQuestion 1Part AWhat is a theme of The Whippoorwill?People sometimes long for what they cannot have.In order to move forward, people must leave the past behind.Nature soothes the heart and calms the mind.There is a balance between nature and the city.Question 2Part BHow does the theme in Part A develop in the poem?The woeful sound of the whippoorwill echos the despair the speaker feels living in the city.The speaker thinks he hears the sound of the whippoorwill while walking in the city.The city sky is filled with cloudy, gray smoke and it makes the speaker feel sad that the moon is hidden.The speaker recalls his fondest memories of nature while living in the city.
