Answer:

Step-by-step explanation:

Surface area of the object = 2 (lw + wh + hl) = 2 (10× 6 + 6 × 10 + 10 × 10)

= 2 ( 60 + 60 + 100) = 2 × 220 = 440 ft.²

Answer:

They are saying that they have this conference room mapped out on a poster board kinda like a road map. But if you put something that big on a board it wont fit. So they had to make it small enough to fit it. When they say that 1/2 on the board is equal to 12 feet in the real room, They are tell you the scale you have to go by. So then they give you 3 1/2 inches on the board. You would see how many 1/2 inches there are in 3 1/2, which is 7, and multiply 7 by 12. The answer would be 84 feet. So they are say that 3 1/2 inches on the poster board, represents 84 feet in the real room.

Answer:

$S_{75}=-506.888989761$ X 10^{32}$

Step-by-step explanation:

Given the sequence

$a_1=-\dfrac{1}{3}\\ a_i=a_{i-1}\cdot (-3)$

$a_2=a_{2-1}\cdot (-3)=a_1 \cdot (-3) = -\dfrac{1}{3}\cdot (-3)=1\\a_3=a_{3-1}\cdot (-3)=a_2 \cdot (-3) = 1 \cdot (-3)=-3\\a_4=a_{4-1}\cdot (-3)=a_3 \cdot (-3) = -3 \cdot (-3)=9\\$

Therefore the sequence is:

$-\dfrac{1}{3}, 1, -3, 9, ...$

This is a geometric sequence where the:

First Term, $a_1=-\dfrac{1}{3}$

Common ratio, r =-3

We want to determine the sum of the first 75 terms.

For a geometric sequence, the sum:

$S_n=\dfrac{a_1(1-r^n)}{1-r} \\$

Therefore:

$S_{75}=\dfrac{-\dfrac{1}{3}(1-(-3)^{75})}{1-(-3)} \\\\=\dfrac{-(1-(-3)^{75})}{4*3}\\\\S_{75}=\dfrac{(-3)^{75}-1}{12}\\\\S_{75}=-506.888989761$ X 10^{32}$

use rates are proportions to convert between units of measurements example - 5 yd= inches please show how you got your work and

frutty [35]

The information tells you that:
1yd = 36 in.
You need to find 5yd, so you need to multiply 1yd by 5. We know that if you do something to one side of an equation, you must do it to the other. Therefore, we multiply 36 inches by 5 as well:
1yd = 36 in.
Multiply both sides by 5
5yd = 180 in.
Therefore, the answer is 180 in. 180 in. equals to 5 yards

Triangle JKM with side j across from angle J, side k across from angle K, and side m across from angle M

Virty [35]

j=43.8 ft

Step-by-step explanation:

Given that ∠K =110° and corresponds to side k=70 ft, then applying the laws of sines then

k/sine∠K =j/sine ∠J

70/sine 110° = j/ sine 36°

j= 70 sin 36° / sin 110°

j=43.785

j=43.8 ft
