Someone please help me with this question. I've been stuck on it for almost 40 minutes. Here's the question. Lauren was standing

on the lifeguard stand on the beach trying to find her sister. She spotted her at the water's edge at an angle of depression of 12 degrees. If the stand is 5 yards above the sand, how far down the beach is Lauren's sister? Round your answer to the nearest yard.

Answer:

24 yd

Step-by-step explanation:

Treat x as the desired quantity.  This x is the side of the triangle adjacent to the lower 12 degree angle.  The side opposite this angle is 5 yds.  Using the definition of the tangent,

tan 12 degrees = opp / adj = 5 yds / x

Then x = (5 yds) / (tan 12 degrees), or x = (5 yds) / 0.213

Then x =  24 yds (to the nearest yd)

Hitman42 [59]

Answer:

7999 \div 4\# lies between 163.245 and 199.975

Step-by-step explanation:

Given

2 digit = 4#

Required

The range of 7999 \div 4\#

Let

\# = 0 --- the smallest possible value of #

So:

7999 \div 40 = 199.975

Let

\# = 9 --- the largest possible value of #

So:

7999 \div 49 = 163.245

<em>Hence, </em>7999 \div 4\#<em> lies between 163.245 and 199.975</em>

Hi! Could you help me me out and solve these two problems? "eight less than the product of seven and xxx", and "the sum of six a
Ann [662]

Given:

The given statement are:

a. Eight less than the product of seven and x.

b. The sum of six and the product of three and d.

To find:

The expression for the given statements.

Solution:

a.

Product of 7 and x is 7×x = 7x.

Eight less than the product of seven and x is 7x - 8.

Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.

b.

Product of 3 and d is 3×d = 3d.

The sum of six and the product of three and d is 6+3d.

Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.

Round 4.645 to the nearest whole number! Please explain step by step to get marked
Gemiola [76]

Step-by-step explanation:

to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.

4.645 rounded to the nearest whole number = 5

Write the recursive formula for -34, -38, -42, -46, -50 ...
Alex787 [66]

Answer:

-30 - 4n

Step-by-step explanation:

-34, -38, -42, -46, -50 ...

the sequence first term is -34

a= -34

Common difference (d) = T2 - T1 = T3 - T2

d = -38- -34 = -42 -  - 38 = -38+34

d = -4

Formula for nth term

Tn = a + (n-1)d

Tn = -34 + (n -1)-4

Tn = -34 -4n + 4

Tn = -30 - 4n

= -30 - 4n

I hope this was helpful, please mark as brainliest
