When the two crews start working together, what part of all the garbage bins will the first garbage truck empty
Answers
Complete question is;
The city just assigned a second garbage truck to empty the bins in Kat’s neighborhood on trash day. The crew from the first garbage truck used to empty all the bins by themselves in 5 hours. In their training, it took the crew from the second garbage truck 8 hours to empty all the bins. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? To the nearest tenth, the first garbage truck will empty about of all the bins.
Answer:
Part of all bins first garbage truck will empty = 0.6
Step-by-step explanation:
Let the total number of bins emptied be denoted by n.
We are told that the crew from the first garbage truck empties all the bins in 5 hours. Thus
Work rate = (n/5) bins/hr
We are told the second garbage truck empties in 8 hours. Thus;
Work rate = (n/8) bins/hr
When both garbage trucks work together, the total amount of time spent will be denoted by x. Thus;
((n/5) + (n/8))x = n
Divide through by n to get;
x/5 + x/8 = 1
Multiply through by 40 to gwt;
8x + 5x = 40
13x = 40
x = 40/13 hrs
To find the part of all the garbage bins the first garbage truck empty when they work together, we will simply multiply the value of x by the work rate of the first garbage truck. Thus;
Part = (n/5) × (40/13)
Part = (40/65)n = 0.615 of n
To the nearest tenth gives 0.6 of n

It moves in a straight line starting from rest. It travels with a constant acceleration for 3 seconds reaching a velocity of 4 m/s. Then it slows down with a constant deceleration of 0.5 m/s squared for 4 seconds before stopping what is the total distance travelled by the toy car?
Answers
Answer:
The total distance traveled by the toy car is 14 m
Step-by-step explanation:
Given;
initial velocity of the car, u = 0
final velocity of the car, v = 4 m/s
time of motion, t₁ = 3 s
constant deceleration of the car, -a = 0.5 m/s²
time of motion, t₂ = 4 s
The total distance traveled by the car, is the area of triangle ABC (check the image uploaded).
[tex]Total \ distance = Area = \frac{1}{2} |BC| \times H\\\\Total \ distance = \frac{1}{2} \times 4\times 7\\\\Total \ distance = 14 \ m[/tex]

Answers
Answer:
5/28
Step-by-step explanation:
P(oj, then grape) = 2/8 x 5/7 = 10/56 = 5/28
The probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
An ice chest contains 2 bottles of orange juice, 5 bottles of grape juice, and 1 bottle of apple juice, all buried in ice.
The probability of pulling out a bottle of orange juice and then a bottle of grape juice is calculated as below:-
Probability = Number of favorable outcomes / Number of sample
P(orange , then grape) = 2/8 x 5/7 = 10/56 = 5/28
Therefore, the probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.

if c= what is the value of a?
Answers
Answer:
a= 17√3/ 2 or a≈14.72
Step-by-step explanation:
c = 17 and is the side opposite to the angle C
c=AB =17
a= BC because is the side opposite to angle A
sin 60° = opp./hyp = BC / AB = BC/17
sin 60° = BC /17 multiply both sides by 17
BC = 17* sin 60 = 17√3/2 ≈14.72

Ryan runs 1.5 miles on his first day of training for a road race. The next day he increases his distance run by 0.3 miles. The day after that increases the distance run by another 0.3 miles and so on. what is the total number of miles Ryan runs over the course of 18 days?
Answers
Answer:
The answer is 72.9 !!!!
Step-by-step explanation:
Trust I'm taking the same test.
Ryan runs a total of 94.5 miles over the course of 18 days.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
We can approach this problem by using arithmetic progression.
The first term is 1.5 miles, and the common difference is 0.3 miles.
So,
The nth term is given by:
an = a1 + (n-1)d
where a1 is the first term, d is the common difference, and n is the number of days.
We want to find the total distance Ryan runs over 18 days, which is the sum of the first 18 terms of the arithmetic progression:
S18 = (n/2) (a1 + an)
where n is the number of terms and a1 and an are the first and last terms, respectively.
Substituting the values we have:
a1 = 1.5 miles
d = 0.3 miles
n = 18
an = 1.5 + (18-1)0.3 = 6 miles
S18 = (18/2)(1.5 + 6) = 94.5 miles
Therefore,
Ryan runs a total of 94.5 miles over the course of 18 days.

Answers
*see attachement below for the diagram
Answer:
(252π + 20) cm²
Step-by-step explanation:
The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)
✔️Curved surface area of cylinder = 2πrh
r = ½(12) = 6 cm
h = 18 cm
C.S.A = 2*π*6*18 = 216π cm²
✔️Area of 1 base = πr²
r = ½(12) = 6 cm
Area = π*6²
Area = 36π
✔️Slant height of the cone = 10 cm
✅The surface area of the resulting solid = 216π + 36π + 2(10)
= (252π + 20) cm²
