Answer:

What is the missing term in the series 9, 27, 31,155, 161, 1127?

First number = 9

Second number = 9*3 = 27

Third number = 27+4 = 31

Fourth number = 31*5 = 155

Fifth number = 155+6 = 161

Sixth number = 161*7 =1127

Seventh number =1127+8 = 1135

Eighth number = 1135*9 = 10215

Ninth number = 10215+10 = 10225

Tenth number = 10225*11 =112475

3(t-7) =6. Solve for the and show steps

Taya2010 [7]

$3(t -7) = 6 \\ 3(t) + 3(-7)\\ 3(-7) = -21 \\ 3t = 3t \\ 3t - 21 = 6 \\Add21: 3t - 21 + 21 = 6 +21 \\ 3t = 21: Divide3 \\ \frac{3t}{3} cancel = \frac{27}{3}keep \\ t = 9$
________________________________________________________________
$8(h - 9) = 8 \\ 8h - 9 = 9 \\ 8h = 8h \\ 8(-9) = -72\\ 8h + (-72) = \\ 8h - 72 = 8 \\ Add72: 8h - 72 + 72 \\ = 8 + 72 \\ divide8 : \frac{8h}{8}cancel = \frac{80}{8} (keep) \\ h = 10$
________________________________________________________________
$9 + 2(z - 2) = 15 \\ 9+2(z)+ 2(-2)= 15 \\ 2(-2) = -4 \\ 9 +2z = ? \\ 9 +2z+4 = 15\\ Subtract5: 2z + 5 -5 \\ = 15 -5 \\ Divide2: 2z = 10 \\ \frac{2z}{2}cancel = \frac{10}{2} = 5 \\ z = 5$

jayden and chandra are cleaning the house. it has 12 rooms, and each room is about the same size. when jayden cleans by himself,

sergij07 [2.7K]

Jayden's work rate is twice Chandra's work rate, and, the rooms cleaned

by Jayden is twice the number of rooms cleaned by Chandra.

Response:

<u>Jayden cleans 8 rooms while Chandra cleans 4 rooms</u>

<h3>Which method can be used to find the number of rooms cleaned by Jayden and Chandra?</h3>

Number of rooms in the house = 12

The time that Jayden takes to clean the house = 6 hours

Time that it takes Chandra to clean the house by herself = 12 hours

Time it takes both of them to clean the house = 4 hours

Required:

The number of rooms that Jayden clean and the number of rooms that

Chandra cleans when they work together.

Solution:

Given that the time it takes Jayden to clean the house is half the time

taken by Chandra.

Therefore;

The number of rooms Jayden cleans in 4 hours is twice the number of rooms cleaned by Chandra, which gives;

Ratio of the number of rooms cleaned by Jayden to the number cleaned by Chandra is 2 : 1

Total number of rooms cleaned = 12

$Number \ of \ rooms \ cleaned \ by \ Jayden = \dfrac{2}{2 + 1} \times 12 = \underline{8 \ rooms}$

The number of rooms cleaned by Chandra = 12 - 8 = <u>4 rooms</u>

How do you find the area of a rectangular prism?

LuckyWell [14K]

Hey there!

Let's first define what area means. Area is for two-dimensional shapes, and expressions how big something is and to what extent. There are formulas that can measure area because these shapes are totally flat, and there's nothing more to measure.

However, when we have three-dimensional figures such as rectangular prisms, we use surface area. Surface area measures the total area that the object takes up, and is a sum of the areas of all the faces. The formula for surface area of a rectangular prism is:

2(lw + wh + lh)

So if we had:

L = 5
W = 6
H = 3

We would have:

A = 2(5×6 + 6 × 3 + 5×3) =
2(30 + 18 + 15) =
2(48 + 15) =
2(63) =
A = 126 units cubed

Notice how it's units cubed because there's 3 dimensions.

Hope this helps!
