Answer: The surface area of the planter will be 120.5 square feet.

In our shape, we will have 5 sides. The base and the four sides going up from each edge of the base.

The base will be 7 x 5 = 35 square feet.

The front and back side will each be 7 x 0.75 = 5.25 square feet.

The left and right side will each be 5 x 0.75 = 3.75 square feet.

If we add up the 5 faces we get:
35 + 5.25 + 5.25 + 3.75 + 3.75 = 120.5 square feet

Need help with problem 40,41 and 42! 15 points

vovikov84 [41]

Answer:

40) w = 32/3

41) x = 23/4

42) w = 1/12

Step-by-step explanation:

40) Real world problem:

If Lisa takes $7\frac{3}{8}$ of the pie from a total of $w$ slices, then the remaining pie is $3 \frac{7}{24}$ . Find w.

So, the equation would become:

$w - 7 \frac{3}{8} = 3 \frac{7}{24}$

$\implies w = 3 \frac{7}{24} + 7 \frac{3}{8}$

This can be written as:

$w = 3 + \frac{7}{24} + 7 + \frac{3}{8}$

This is equivalent to $3 + \frac{7}{24} + 7 + \frac{9}{24}$

Since, the denominator is the same, the numerators can be added now.

$\implies w = 10 + \frac{16}{24}$

$\implies w = 10 + \frac{2}{3}$

$i.e., w = 10 \frac{2}{3} = \frac{32}{3}$

Hence, the answer is 32/3.

41) The given equation is: $2 \frac{1}{2} + x = 8\frac{1}{4}$

$2 \frac{1}{2} = \frac{5}{2}$ and

$8 \frac{1}{4} = \frac{33}{4}$

So, $x = \frac{33}{4} - \frac{10}{4}$

$\implies x = \frac{23}{4}$

The answer is 23/4.

42) The given equation is $$ w - \frac{1}{3} = \frac{5}{12}$

$\implies w = \frac{5}{12} - \frac{1}{3}$

$w = \frac{5}{12} - \frac{4}{12}$

$w = \frac{1}{12}$

The answer is 1/12.

Insert five geometric means between 1/8 and 8. There are supposed to be 2 answers

AnnyKZ [126]

Answer:

Step-by-step explanation:

In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a = 1/8

n = 7 terms

Since the last term is 8, then

8 = 1/8 × r^(7 - 1)

Multiplying through by 8, it becomes

64 = r^6

Taking the 6th root of both sides of the equation, then

r = 2

The 5 geometric means would be

1/8 × 2 = 1/4

1/4 × 2 = 1/2

1/2 × 2 = 1

1 × 2 = 2

2 × 2 = 4

The sequence is

1/8, 1/4, 1/2, 1, 2, 4, 8

70 sixth-graders had an average weight of 90 pounds. 30 seventh graders had an average weight of 100 pounds. What was the averag

Brrunno [24]

We know that 70 sixth graders had an average weight of 90 pounds, and 30 seventh graders had an average weight of 100 pounds.

We know that the weight of all 70 sixth graders will be 70*90, since we're multiplying the total amount of students by the average.

Using this same logic tells us that the total weight for the 30 seventh graders is 30*100

The average weight for all 100 students will be the total weight of the sixth graders (which is 70*90) added with the total weight of the seventh graders (which is 30*100), then finally divided by the total amount of students in the sample space (which is 100).

$\dfrac{70(90)+30(100)}{100}$

$=\dfrac{6300+3000}{100}$

$=\dfrac{9300}{100}$

$=93$

The average of all 100 students is 93 pounds.

Let me know if you need any clarifications, thanks!
