Mathematics

Answer:

288

Step-by-step explanation:

First, find how much of the desk each person can finish in 1 hour. Paul can finish 1/12 because he finishes the whole thing in 12 hours and Shawn can finish 1/8 because he finishes the whole thing in 8 hours.

Then find a common denominator and add those together to find how much they could do together in 1 hour.

2/24 + 3/24 = 5/24 So they can finish 5/24 of the desk in 1 hour if they work together.

So to finish 24/24 of the desk, they'll need to do 4 hours (20/24 of the desk) and 48 minutes (4/24 of the desk)

It asked for the number of minutes, so multiply 4 by 60 and add 48 to find the total number of minutes. 4*60 = 240 and 240 + 48 = 288

So it will take them 288 minutes to build the desk together.

you send 12 photos to a company that makes personalized wall calendars the company enlarges the photos and inserts one for each

Assoli18 [71]

Answer:

15 inches

Step-by-step explanation:

We have that,

Length of the photo = 4 inches and Width of the photo = 6 inches

Also, the width of the image on the calendar = 10 inches

Let, the length on the image of the calendar = x inches.

Since, the ratio of the photo and its image will remain same, we get,

$\frac{4}{6}=\frac{10}{x}$

i.e. $x=\frac{60}{4}$

i.e. x = 15

Hence, the length of the image of the photo on the calendar is 15 inches.

Which of the following is a geometric sequence?

iogann1982 [59]

Answer:

Let's start by first remembering what a "geometric sequence" is. A geometric sequence is a sequence of numbers that multiply by the same number each time. For example,

2, 4, 8, 16

is a geometric sequence since each number is multiplied by 2 from one to the next, but

2, 4, 6, 8

is NOT a geometric sequence. We are adding 2 each time, but not multiplying, so it doesn't count. We have to be multiplying to have a geometric sequence.

[A] Let's look at A, are we multiplying by the same thing?

6*3 = 18

18*3 = 54

54*3 = 162

162*3 = 486

Yes! We are multiplying by 3 each time. This is a geometric sequence!

[B] Are we multiplying by the same thing?

2*3/2 = 3

3*3/2 = 9/2 which is not 5.

NOPE

[C] Are we multiplying by the same thing?

2*5/2 = 5

5*5/2 = 25/2 which is not 8

NOPE

[D] Are we multiplying by the same thing?

-4*1/2 = -2

-2*1/2 = -1

-1*1/2 = -0.5

-0.5*1/2 = -0.25

-0.25*1/2 = -0.125

Yep, we are multiplying by 1/2 each time! This is a geometric sequence!

hope this help im not sure tho

Trigonometric ratio: find an angle measure

drek231 [11]

Answer:

$T =56.3$

Step-by-step explanation:

Given

The attached triangle

Required

Measure of T

This is calculated as:

$\cos T = \frac{Adjacent}{Hypotenuse}$

$\cos T = \frac{5}{9}$

Take arccos

$T = \cos^{-1}{(5/9)}$

$T =56.3$
