Mrs. Lavetan has 45 to complete her writing paper. She spend 10 and 1/8 min to planning her paper and 15 and 1/2 minutes weighti

Flura [38]

Answer: 20 minutes

Step-by-step explanation:

She has 45 mins to complete her writing paper.

She spends: $10\frac{1}{8}$ minutes to plan her paper.

She spends: $15\frac{1}{2}$ minutes writing rough drafts.

How much time left does she have?

$45-(10\frac{1}{8} +15\frac{1}{2})$

$45-(10+15(\frac{1}{8}+\frac{1}{2}))$

$45-(25\frac{(1)(2)+(8)(1)}{(8)(2)})$

$45-(25\frac{2+8}{16} )$

$45-(25\frac{10}{16})$ Simplify the fraction.

$45-(25\frac{5}{8})$

$45-25(\frac{5}{8})$

So she has approximately,

$20\frac{5}{8} =\frac{165}{8}= 20$ minutes.

At 3:30 in the afternoon in mid-September the Kimball Tower casts a shadow about 290 feet long when the sun's rays come down at

ioda

Answer:

203 feet.

Step-by-step explanation:

Please find the attachment.

Let h represent the height of the building.

We have been given that at 3:30 in the afternoon in mid-September the Kimball Tower casts a shadow about 290 feet long when the sun's rays come down at an angle about 35 degrees above the horizontal.

We know that tangent relates opposite side of a right triangle to its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

Upon substituting our given values in above formula, we will get:

$\text{tan}(35^{\circ})=\frac{h}{290}$

$290*\text{tan}(35^{\circ})=\frac{h}{290}*290$

$290*0.70020753821=h$

$h=290*0.70020753821$

$h=203.0601860809$

$h\approx 203$

Therefore, the building is approximately 203 feet high.
