The total cost of a tablet device comprises the cost of material, labour and overheads in the ratio 3:4:1. The cost of material is $315. What is the total cost of the tablet?
Answers
Answer:
$840
Step-by-step explanation:
Given data
The cost of material is $315
The ratio is
3:4:1
The total number of part is
3+4+1= 8
Let us apply the part to all method
let the total cost be x
hence
3/8=315/x
cross multiply
3x= 8*315
3x= 2520
divide both sides by 3
x= 2520/3
x= $840
Hence the total money is $840

Extra Example 3: Hazel has $23.28 in her purse. She has $5.60 more than Nixon.
Paul says that Nixon has $28.88. Yolanda says that Nixon has $17.68. Who is
correct?
Answers
Answer:
Yolanda is correct.
Step-by-step explanation:
If Hazel has $23.28 and $5.60 more than Nixon, then Nixon will have $17.68 because 23.28-5.60 is 17.68.
The only way Paul would be right is if Nixon has $5.60 more than Hazel because 23.28+5.60 is 28.88.
Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 2 inches, and the larger gear has a radius of 7 inches.
Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation?
Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear?
Show all work.
Answers
Answer:
Let r represent the radius of the smaller circle and R the radius of the larger circle.
Apply ratios: the radius of smaller circle to radius of larger circle, i.e.
r: R = 3 : 7.
I complete rotation = 360 degrees.
Part 1:
For one complete rotation of the smaller circle, the larger circle is rotated through: (3/7)*(360) = 154.3 degrees
Part 2:
For one complete rotation of the larger circle, the larger circle is rotated through: (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios:
The number of rotations = R/r = 7/3 = 2.3 rotations

Answer:
Step-by-step explanation:
for smaller gear circumference=2π×2=4π inches
for larger gear
l=4π
θ=l/r
θ=(4 ×180)/7=720/7=102 .9°
for larger gear circumference=2π×7=14π
number of rotations=(14π)/4π=7/2=3.5 rotations or 3 1/2 rotations.

The Dial and the Lewis families when to Taco Box for dinner. The Dials bought 3
burrito meals and 4 taco meals for $48. The Lewis' bought 6 burrito meals and 2
taco meals for $60. How much does a burrito meal cost? How much does a taco
meal cost?
Answers
Answer:
A burrito costs $8, while a taco costs $6.
Step-by-step explanation:
Given that the Dial and the Lewis families when to Taco Box for dinner, and the Dials bought 3 burrito meals and 4 taco meals for $ 48, while the Lewis' bought 6 burrito meals and 2 taco meals for $ 60, to determine how much does a burrito meal cost and how much does a taco meal cost make the following calculations:
3B + 4T = 48
3B = 48 - 4T
6B + 2T = 60
6B = 60 - 2T
3B = 30 - 1T
30 - 1T = 48 - 4T
30 = 48 - 4T + 1T
30 - 48 = -3T
-18 = -3T
-6 = -T
6 = T
3B + 4x6 = 48
3B + 24 = 48
3B = 24
B = 24/8
B = 8
6x8 + 2x6 = 60
48 + 12 = 60
60 = 60
Thus, a burrito costs $ 8, while a taco costs $ 6.

Equation: y = -x + 1/4
Step-by-step explanation:
You start by finding the slope using the slope formula. Then after finding the slope you use one of the pairs to substitute in the equation y = mx+b then after doing that you solve for your b since it will be the only missing variable. Then you have your equation.
