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

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes
For fraction multiplication, multiply the numerators and then multiply the denominators to get

Robin invested $1000 in a 12% simple interest savings deposit for 3
years. He also invested an equal amount in a 10% compound interest
savings deposit for 3 years. At the end of 3 years, how much more
interest did he get from the simple interest deposit?
Step-by-step explanation:
Lets find out,shall we?
Simple interest=(PRT)/100
=$1000×12×3)/100
=$360
Now for compound interest
A=P(1+R/100)^t
A=$1000(1+12/100)^3
A=$1404.928
so interest for compound interest=$(1404.928-1000)=$404.928
Clearly,Robin got more interest by compound interest than simple interest which business people understand lol.
Difference in interest=$404.928-360=$44.928

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.

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.

The standard deviation is approximately 0.10. Lines indicate a distance of 1 and 2 standard deviations above and below the mean.
Answer:
The answer is "1.5".
Step-by-step explanation:
Given value:
[tex]p= 60 \% = \frac{60}{100}= 0.60\\\\\sigma_p = 0.10 \\\\\hat{p} =0.75[/tex]
