A car travels 450km at 100km/h and 90km at 60km/h. Find its average speed?
Answer:
Average speed = 90 km/h
Step-by-step explanation:
Given that:
Distance covered at 100 km/h = 450 km
Time = [tex]\frac{Distance}{Speed}[/tex]
Time = [tex]\frac{450}{100}=4.5\ hours[/tex]
Distance covered at 60 km/h = 90 km
Time = [tex]\frac{90}{60}=1.5\ hours[/tex]
Total distance travelled = 450 + 90 = 540 km
Total time taken = 4.5 + 1.5 = 6 hours
Average speed = [tex]\frac{Total\ distance}{Total\ time}[/tex]
Average speed = [tex]\frac{540}{6}[/tex]
Average speed = 90 km/hr
Hence,
Average speed = 90 km/h

(15, 0) = (movies, games)
Step-by-step explanation:
If the goal is to purchase as many items as possible, that is best reached by spending all of the money on the least-expensive items. Purchase of 15 movies (at $20 each) will do what Lane wants.
(movies, games) = (15, 0)

Peter is typing an essay for his science class. The essay needs to be 8,100 words long. Peter can type 25 words per minute. If Peter has 600 words typed so far, how many hours will it take for Peter to finish typing the essay
Answer:
5 hours or 300 minutes
Step-by-step explanation:
If Peter has already written 600 words, he has 7,500 words left to write. If he can write 25 words per minute, it will take 300 minutes for him to finish because 7,500/25=300. 300 minutes can be converted to 5 hours.
Find 4/9 of 6:9 in simplest form
Answer:Change values to whole numbers.
Convert any mixed numbers to fractions.
Convert 3 1/8
3 1/8 = 25/8
We now have:
5 : 3 1/8 = 5 : 25/8
Convert the whole number 5 to a fraction with 1 in the denominator.
We then have:
5 : 3 1/8 = 5/1 : 25/8
Convert fractions to integers by eliminating the denominators.
Our two fractions have unlike denominators so we find the Least Common Denominator and rewrite our fractions as necessary with the common denominator
LCD(5/1, 25/8) = 8
We now have:
5 : 3 1/8 = 40/8 : 25/8
Our two fractions now have like denominators so we can multiply both by 8 to eliminate the denominators.
We then have:
5 : 3 1/8 = 40 : 25
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 40 and 25 is 5
Divide both terms by the GCF, 5:
40 ÷ 5 = 8
25 ÷ 5 = 5
The ratio 40 : 25 can be reduced to lowest terms by dividing both terms by the GCF = 5 :
40 : 25 = 8 : 5
Therefore:
5 : 3 1/8 = 8 : 5

B. By translating the graph of f(x) five units to the up
C. By translating the graph of f(x) five units to the left
D. By translating the graph of f(x) five units to the down
Answer:

Step-by-step explanation:
Consider the function f(x)=x^3+7. What is the inverse of f(x)?
Step-by-step explanation:
f(x)=x^3+7
y=x^3+7
x=y^3+7
y^3=x-7
y=cube root (x-7)
f(x) inverse=cube root of x-7
The inverse function of the given function is [tex]y=\sqrt[3]{(x-7)}[/tex].
The given function is f(x)=x³+7.
What is the inverse function?Inverse function is represented by [tex]f^{-1[/tex] with regards to the original function [tex]f[/tex] and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
Now, f(x)=x³+7 can be written as y=x³+7
⇒ x=y³+7
⇒ y³=x-7
⇒ [tex]y=\sqrt[3]{(x-7)}[/tex]
Therefore, the inverse function of the given function is [tex]y=\sqrt[3]{(x-7)}[/tex].

At Grocery Mart, tomatoes are $2.75 per pound, or you can buy a 5
pound box for $11.
a) What is the unit price for the first tomato option?
b) What is the unit price for the second tomato option?
c) Based on price, which is the better value option?
HELP ME PLEASE ITS TIMEDDDD
Answer:
a) $2.75
b) $2.2
c) Second tomato option is better value option.
Step-by-step explanation:
First option to buy tomatoes = $2.75 per pound
Second option to buy tomatoes:
To buy a box which is a 5 pound box and the price is $11.
To find:
a) Unit price for the first tomato option.
b) Unit price for the second tomato option.
c) Better value option on the basis of price.
Solution:
Let the consider the unit here to be a pound.
So, we will find the price of tomato per pound to find the unit price of tomato.
a) Unit price of the first tomato option is : $2.75 per pound
b) Unit price of the second tomato option:
Price for 5 pounds = $11
Dividing both sides with 5 to find the price of 1 pound or unit price.
Price for [tex]\frac{5}{5}[/tex] = 1 pound = [tex]\frac{\$11}5 = \$2.2[/tex]
c) To find the better value option, we can compare the unit prices of the two tomato options.
Here, we have the two tomato options with unit prices as:
$2.75 and $2.2
Second tomato option has a lower unit price, therefore, second option is better value option on the basis of price.

3n + 33 = 4n + 4
33 = n + 4
29 = n
Which of the following methods can be used to find the derivative of y = arcsin x with respect to z ?
|. Use the quotient rule to differentiate
II. Use the chain rule to differentiate sin(arcsin x) = 2.
III. Use implicit differentiation to differentiate the function y in the relation sin y = x with respect to z.
A) I only
B) Ill only
C) II and III only
D) I, II, and III
Answer:
B) Ill only
Step-by-step explanation:
This is because y = arcsin x can be re-written as sin y = x, We then differentiate sin y = x implicitly with respect to z to obtain
d(siny)/dz = dx/dz
(cosy)dy/dz = dx/dz
dy/dz = (1/cosy)dx/dz

The larger of two numbers is 10 more than three times the smaller number the sum of the two numbers is 54 find the two numbers
Answer:
x = 11
y = 43
Step-by-step explanation:
x = small number
y = large number
Set up a system of equations:
y = 10 + 3x
x + y = 54
Solve system by substitution: x + 10 + 3x = 54
4x + 10 = 54
4x = 44
x = 11
x + y = 54
11 + y = 54
y = 54 - 11
y = 43

which of the following statements are true about the points (5,3) and (5,-3) is true
A. is in the same quadrant
B. is a reflection of each other over the y-axis
D. is a reflection of each other over the x-axis
C. reflections over both axis
Answer:
we can say that the points are reflection of each other over the x-axis.
Option D is correct option.
Step-by-step explanation:
We need to find which of the following statements are true about the points (5,3) and (5,-3) is true.
We are given a point (5,3)
and other point (5,-3)
We know that refection over x-axis states that the value of y-coordinate will be negated while x-coordinate value remain same.
In our case, first point (5,3) the coordinates are: x=5, y=3
The other point (5,-3) the coordinates are: x=5, y=-3
The x-coordinate value remains same while, y-coordinate value is negated (negative)
So, we can say that the points are reflection of each other over the x-axis.
Option D is correct option.
Answer: Option D is the correct option.
Step-by-step explanation:
We need to find which of the following statements are true about points (5,3) and (5,-3) is accurate.
We are given a point (5,3)
and another point (5,-3)
We know that reflection over the x-axis states that the value of the y-coordinate will be negated while the x-coordinate value remains the same.
In our case, for the first point (5,3) the coordinates are x=5, y=3
The other point (5,-3) the coordinates are: x=5, y=-3
The x-coordinate value remains the same while, the y-coordinate value is negated (negative)
So, we can say that the points are reflections of each other over the x-axis.
