Let the smaller number = X
Then the larger number is 3x+4 ( four more than 3 times the smaller number)
The sum of both numbers = 80
so you have X + 3X+4 = 80
Simplify the left side:
4x+4 = 80
Subtract 4 from each side:
4x = 76
Divide both sides by 4:
X = 76/4
X = 19
The smallest number is 19
The largest number is 80 - 19 = 61 ( check: 3*19 = 57+4 = 61)
The two numbers are 19 and 61
Step-by-step explanation:
We can use the expression (22 x 40) + (22 x 6).
By definition, the arc length is given by:
arc = (theta) * (R)
Where,
theta: central angle
R: radius
Substituting values we have:
arc = (π / 5) * (2.8)
Rewriting we have:
arc = ((3.14) / 5) * (2.8)
arc = 1.7584 cm
Round to the hundredth:
arc = 1.76 cm
Answer:
the arc length is:
arc = 1.76 cm
Given:
one person can produce:
E = <span>300 BTUs of body heat per hour
dimensions of the bedroom is:
V = </span><span>15 ft × 12 ft × 10 ft
required: is the energy per volume if 2 persons sleeps in 7 hours
let T be the total energy produce per volume
T = (</span><span>300 BTU per hour per person) ( 7 hours) ( 2 person) / ( </span> <span>15 ft × 12 ft × 10 ft)
T = 2.3 BTU / ft^3</span>
Answer:
0.08 cubic feet.
Step-by-step explanation:
You have a small marble statue of Mozart that is 10 inches tall and is made of 16 cu. inches of marble.
The original statue in Vienna is 7 feet tall.
First we will convert this to inches as one relation is given in inches.
1 feet = 12 inches
7 feet = 
inches
Let the amount of marble used for 84 inches statue be = x
We can relate both the conditions in the following way:
x = 134.40 cubic inches
Now, 1 cubic inch = 
cubic foot
So, 134.40 cubic inches = 
cubic foot
= 0.0777 cubic feet rounding to 0.08 cubic feet.
