Oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. What was the total average speed?
Answer:
46.6666667
Step-by-step explanation:
we need to know the TOTAL average speed. To do that, we need to know how to get the speed, which is distance/time. Now we have to substitute. The equation we get is: s= (90+120)/(1.5+3). After solving, you should get s= (210miles)/(4.5hrs). Now all we have to do is divide, which equals 46.6666667.
Hope this helps! (:
The required average speed of Oliver is 46.67 miles per hour.
Given that,
Oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours, what was the total average speed is to be determined.
Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.
What is average?The average of the values is the ratio of the total sum of values to the number of values.
Here,
Total distance traveled = 90 + 120 = 210 miles
Total time taken = 1.5 + 3 = 4.5 hours
Average speed = distance / time
= 210 / 4.5
= 46.67 miles per hour
Thus, the required average speed of Oliver is 46.67 miles per hour.

Answer:
The slope is -3/2
The y intercept is (0, -5) :)
Step-by-step explanation:
the slope is whatever is times by x
the y intercept is what’s being subtracted by it
The values of m and b from the equation of the given line are;
m = -3/2 and b = -5
Slope intercept formWe are given the equation;. y = -(3/2)x - 5
Now, the general form of an equation of a line in slope intercept form is;
y = mx + b
Where;
m is slope
b is y-intercept
Thus, comparing the general form to our given equation, we can see that;
m = -3/2 and b = -5

Complete the table for the given rule.
Rule: y is 1 less than 2 times x
According to the rule, the table is:
x|y
2|3
3|5
4|7
The translation of the rule to a math expression is:
[tex]y = 2x - 1[/tex]
Then, for x = 2:
[tex]y = 2(2) - 1 = 4 - 1 = 3[/tex]
For x = 3:
[tex]y = 2(3) - 1 = 6 - 1 = 5[/tex]
For x = 4:
[tex]y = 2(4) - 1 = 8 - 1 = 7[/tex]
Thus, the table is:

Which is more, 9 pints or 16 cups?
Answer:
9 pints
Step-by-step explanation:
there are two cups in a pint, so we need to divide 16 by 2 to convert the cups to pints.
16 ÷ 2 = 8
9 is greater than 8, so 9 pints.
The scale of a map says that 4 cm represents 5 km. a. what distance on the map (in centimetres) represents an actual distance of 4 kilometres? b. What is the actual number of kilometres that is represented by 5 centimetres on the map?
Answer:
a. 3 cm
b. 6 km
Step-by-step explanation:
to be completely honest, I just shoot my answer based on the pattern.
if you notice that when the scale is 4 cm, the actual distance is 5 km. When the distance is 4 km, the scale should probably be 3 cm. It's the same with the 5 cm scale, then the distance should be 6 km
Step-by-step explanation:
Use ratios to solve it
a)
4 cm → 5 kmx cm → 4 kmx = 4*4/5 = 3.2 cm
b)
4 cm → 5 km5 cm → x kmx = 5*5/4 = 6.25 km

5. Kathy plans to purchase a car that
depreciates (loses value) at a rate of 14% per
year. The initial cost of the car is $21,000.
How much will the car be worth
in 6 years?
Answer:
At the end of the 1st year you have 21,000-0.14(21000)
= (1-0.14)21000 = 0.86(21,000)
So after three years you have 21000(0.86)(0.86)(0.86)
= 21000(0.86)^3
Answer:
3360
Step-by-step explanation:
Find 14% of 21,000 then multiply by six which gives you 17,640. Then you subtract 21,000-17640. that is your answer.

If a seed is planted, it has a 95% chance of growing into a healthy plant.
If 7 seeds are planted, what is the probability that exactly 3 do grow? Round to 4 decimal places.
If 7 seeds are planted, the probability that exactly 3 do grow is;
P(X = 3) = 0.0002
This is a binomial probability distribution problem where;
P(X = x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾
We are given;
p = 95% = 0.95
q = 1 - p
q = 1 - 0.95
q = 0.05
Thus If 7 seeds are planted, the probability that exactly 3 do grow is;
P(X = 3) = ⁷C₃ × 0.95³ × 0.05⁽⁷ ⁻ ³⁾
P(X = 3) = 35 × 0.857375 × 0.00000625
P(X = 3) = 0.000187
To four decimal places gives;
P(X = 3) = 0.0002
