Jim began a 146-mile bicycle trip to build up stamina for a triathlete competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 5 hours. If Jim walks at a rate of 4 miles per hour and rides at 40 miles per hour, find the amount of time he spent on the bicycle.
Answer:
3.5 hours
Step-by-step explanation:
Let us represent
The time spent walking as x
The time spent riding as y
Jim began a 146-mile bicycle trip to build up stamina for a triathlete competition. Unfortunately, his bicycle chain broke, so he finished the trip walking. The whole trip took 5 hours.
Hence:
x + y = 5.... Equation 1
x = 5 - y
If Jim walks at a rate of 4 miles per hour and rides at 40 miles per hour,
The formula for Distance = Speed × time. Hence,
4 × x + 40 × y = 146 miles
4x + 40y = 146.... Equation 2
We substitute 5 - y for x in Equation 2
4(5 - y) + 40y = 146
20 - 4y + 40y = 146
Subtract 20 from both sides
20 - 20 - 4y + 40y = 146 - 20
- 4y + 40y = 146 - 20
36y = 126
y = 126/36
y = 3.5 hours
Since the time he spent raiding his bicycle is represented by "y", the amount of time he spent on the bicycle is 3.5 hours

Julio says, " If you subtract 19 from my number and multiply the difference by - 4, the result is - 72." What is julios Number?
Answer:
37
Step-by-step explanation:
If you do the reverse equation, that is -72 divided by -4 which gives you 18. Then you add 19 to that 18 and you get 37.
Answer:
the answer is 37
Step-by-step explanation:
37 - 19 = 18
18 x -4 = -72

if a person is selected at random from this group of 1,000 people, determine the probability that he or she does not wear eyeglasses while driving even though he or she needs to wear it.
The probability is 7/5.
A person is randomly selected from a group of 1000 people.
We have,
440 people use glasses and must wear them.
20 wear glasses but are not required to do so.
140 people who should wear glasses but don't
400 if you don't need to wear glasses, don't wear them.
Therefore, the probability that the person does not wear glasses while driving even though he or she needs to wear them is:
P ( he or she does not wear glasses and needs to wear them / Total number of people surveyed ) = 140 / 100
P = 14 / 10
P = 7 / 5
The probability that he or she drives without wearing eyeglasses despite the fact that they are required is 7 in 5.

The first term of a geometric sequence is 3 and the 4th is 1029. find the two terms between the 1st and the 4th.
Two terms between the 1st and the 4th in the given geometric sequence is 21 and 147.
The formula for the nth term in a geometric sequence is given by:
a(n) = a(1) . rⁿ⁻¹
Where:
a(1) = first term
r = common ratio
Parameters given:
a(1) = 3
a(4) = 1029
Substitute n = 4 into the formula:
a(n) = a(1) . rⁿ⁻¹
a(4) = 3 . r³
1029 = 3 . r³
r³ = 1029/3 = 343
r = 7
Two terms between the 1st and the 4th term is a(2) and a(3).
In a geometric sequence, the following applies:
a(n) = a(n-1) . r
Hence,
a(2) = 3 . r
= 3 . 7 = 21
a(3) = a(2) . r
= 21 . 7 = 147

Can anyone help me pleaseee
an open box of maximum volume is to be made from a square piece of material, 26 centimeters on a side,
Domain of the function is: 0 < x < 12.
Volume of the box = 4x(12-x)²cm^3
Volume of a cuboid:Volume is the measure of how much space a given substance takes up inside a closed, three-dimensional object. A cuboid's volume given by its length (l), breadth (b), and height (h) is as follows:
According to the given data:Side of square = 24cm
(a) Volume of the box
Let the squares used to create a box have a side of "x" cm.
so,
length will be = 2(12 - x)
Width will be = 2(12 - x)
Hight will be = x
Volume of the Square box (V) = l x b x h
= 2(12 - x) * 2(12 - x) * (x)
= 4x(12-x)²cm^3
(b) The domain of the function V(x)
We see that:
x is length, x >0
x cm of the side's length of 24 cm are removed from both ends.
so that 2x<24
Domain of the function is: 0 < x < 12.

In rhombus MNOP, side NO equals 45mm. What is the length of
OP
PM+MN
the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.
We are given a rhombus MNOP
We know that, a rhombus is a quadrilateral in which there are 4 sides and all the sides are equal.
We are given the length of the side NO as:
NO = 45 mm
Now, we need to find the length of side OP.
OP = 45 mm ( as NO = OP)
Also, we need to find PM + MN
PM + MN = NO + NO ( as PM = MN = NO )
= 2 NO
= 2 × 45 mm
= 90 mm
Therefore, we get that, the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.
