Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.
The correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
For example:
[tex]0.99 = \dfrac{99}{10^2} = \dfrac{99}{100}[/tex]
(10 raised to power k = 1 followed by k zeroes)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we can see from the image that:
Weight shown = 3 pounds + half more pound + half of 1/10 pound more approx. (as the weight hand is approx between 5 and 6 minor ticks after the big 3 pound mark). In each minor mark, one pound is divided in 10 parts, so each minor tick adds up 1/10 of a pound. Half of 1/10 shows that after 5, the hand is not exactly on 6 but sort of in between them, so approximately half.
Thus, weight shown ≈ 3 + 0.5 (half is written 0.5 too) + 1/10 of 0.5 pounds
= 3 + 0.5 + 0.5/10 = 3.5 + 0.05 = 3.55 pounds
Thus, the weight is approx 3.55 pounds.
Converting it to fraction, we get:
[tex]3.55 = \dfrac{355}{100} = \dfrac{5 \times 71}{5 \times 20} = \dfrac{71}{20}[/tex] pounds.
Thus, the correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

Answer:
343 ft^2 (Closest to Answer D)
Step-by-step explanation:
The triangle on the left has height 24 ft and base 18 ft, and therefore, by the area-of-a-triangle formula A = (1/2)(b)(h), the area of the triangle is
A = (1/2)(24 ft)(18 ft) = 216 ft^2.
The semicircle on the right has radius (18 ft)/2, or 9 ft. Using the area-of-a-semicircle formula A =(pi)(r)^2/2, we find this particular semicircle to have area
A = (pi)(9)^2/2, or approximately 127 ft^2
Adding these two subareas together results in total area
A = (216 ft^2) + (127 ft^2) = 343 ft^2 (Answer D)

Walden gives the pizza delivery person an $8.00 tip, which was 12% of the cost of his pizzas. How much was the total amount that Walden spent? Round your answer to the nearest cent.
ANSWERS WITH WEIRD FILE THINGYS WILL BE REPORTED IMMEDIATLY
Answer:
$17
Step-by-step explanation:
Tip = $8.00
Pizzas cost:
First you have to do 12% of $8.00 which = $0.96
Then you have to add the $0.96 to the $8.00 which = $8.96
Total = $8.00 + $8.96
= $16.96
then round it to nearest cent which is $17
Answer:
$74.67
Step-by-step explanation:
$8 was 12% of the cost of the pizzas, so we have to add that to the initial cost. The initial cost can be found by (8*100)/12, which would be $66.67. Since we need to find the total amount of money spent, we have to add the initial cost of pizzas and the $8 tip, which is 12% of that. Final answer is $74.67

What is the formula for the volume of a trapezoidal prism?
Answer:
Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?
Answer:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.
Step-by-step explanation:
The given is,
One train travels at an average speed of 80 km/hr
The other travels at an average speed of 70 km/hr
Step:1
Formula to calculate the distance traveled by two trains,
Distance traveled by two trains = (Rate of speed of train one +
Rate of speed of other train) × Time
From the given the above equation becomes,
Let, h = Time taken to each the distance
50 = ( 80 + 70 ) h
50 = (150) h
= 0.3333 hours
= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )
h = 20 minutes
Step:2
Check for solution,
From equation (1),
50 = ( 80+70 ) (0.3333)
50 = (150)(0.3333)
50 = 50
Result:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.
