Find the variable of each ............

Mathematics
1 answer:
QveST [7]3 years ago
4 0

Answer:

The answer is option d.

To find a we have to first find b

sin 60° = b / 10

b = 10 sin 60°

b = 5√3

sin 30° = b / a

b = 5√3

a = 5√3 sin 30°

a = 10√3

cos 30° = c / a

a = 10√3

c = 10√3 sin 30°

c = 15

cos 60° = d /10

d = 10 cos 60°

d = 5

a = 10√3 , b = 5√3 , c = 15 and d = 5

Hopethis helps.

A carton measures 3 feet by 2 feet by 2 feet. A machine can fill the carton with packing material in 3 seconds. How long would i
True [87]
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³

Therefore: 
A machine can fill 12 ft³ in 3 seconds.

2) we calculate the volume of the second carton. 
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

12 ft³---------------------3 seconds
120 ft³--------------------      x

x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.

answer: 30 seconds.

(Algebra 1) I HAVE BEEN STUCK ON THIS PROBLEM AND I NEED YOUR HELPPPP!!!!!!
larisa [96]

Answer:

d = (1/20) t + 2

Step-by-step explanation:

∵ The equation of Monika is:

  d = (1/15)t + 1 ⇒ linear equation

∴ The slope of the line = 1/15 ⇒ speed of Monika

∵ The speed of Mark is 3/4 as fast as Monika

∴ The speed of Mark = 3/4 × 1/15 = 1/20

∵ Mark starts a mile behind her

∵ at t = 0 ⇒ her distance is 1

∴ at t = 0 ⇒ his distance is 2

∴ His equation is d = (1/20) t + 2

How do i add 6.75 & 3.75?​
Stella [2.4K]

Answer:

It's like adding whole numbers, but with a dot. add 75+75=150

Because 150 is more than 100, you add the 1 to the whole numbers, the 6 and the 3. Add 3+6+1=10

So your answer is 10.5
