It is about a 425-mile drive from San Jose to
Los Angeles down CA-1, and about a 320-
mile drive from San Jose to Santa Barbara
along the same route.
If you stop in Santa Barbara, you can take a
walk along the water front, or visit the Santa
Barbara Zoo.
How far is the drive from
Santa Barbara to Los Angeles?
Answer:
105
Step-by-step explanation:
425 - 320 = 105 miles
Final answer:
The drive from Santa Barbara to Los Angeles is 105 miles, which is the difference between San Jose to Los Angeles (425 miles) and San Jose to Santa Barbara (320 miles).
Explanation:
The question asks how far it is to drive from Santa Barbara to Los Angeles. To determine this distance, we utilize the total distance from San Jose to Los Angeles and subtract the distance from San Jose to Santa Barbara. Starting with the overall distance of San Jose to Los Angeles, which is 425 miles, we deduct the San Jose to Santa Barbara distance of 320 miles. This calculation will provide us with the distance from Santa Barbara to Los Angeles.
By subtracting 320 miles from 425 miles, we find that the distance from Santa Barbara to Los Angeles is 105 miles.
There are four accent walls that need to be painted: cafeteria, gym, auditorium, and entrance. The art class is going to paint either a forest or an ocean nature scene on one of them. What is the probability that the ocean scene is painted in the gym?
Answer:
12.5%
Step-by-step explanation:
There are 4 walls to choose from, and 2 scenes to choose from. So the number of combinations is 2×4=8. One of those is the ocean scene on the gym wall. So the probability is:
P = 1/8
P = 12.5%

Step-by-step explanation:
Alex completed 7 homework problems in class. The function p(m) relates the
time (in minutes) Alex spent on his homework at home to the total number of
problems he completed. The input is the number of minutes worked. The
output is the number of problems completed.
p(m)=m/4+7
Which equation represents the inverse function m(p), which uses problems
completed as the input and gives minutes worked as the output?
The answer is:
D. [tex]m(p)=4p-28[/tex]
Why?Inversing a function consists of switching the function (name) and the variable, so, where we have the variable (m for this case) we should rewrite it as the function (p(m)), and then, isolate the function in order to know the inverse function.
So, we are given the function:
[tex]p(m)=\frac{m}{4}+7[/tex]
We know that:
[tex]p(m)^{-1}=m(p)[/tex]
Then, rewriting and calculating, we have:
[tex]p(m)=\frac{m}{4}+7[/tex]
[tex]p=\frac{m(p)}{4}+7\\\\p-7=\frac{m(p)}{4}\\\\m(p)=(p-7)*4=4p-28[/tex]
Hence, we have that the answer is:
D. [tex]m(p)=4p-28[/tex]

Which table of ordered pairs represents a proportional relationship?
Answer:
The correct option is 3.
Step-by-step explanation:
We need to find a table of ordered pairs that represents a proportional relationship.
Proportional relationship: It means y-values are proportional to x-values.
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
For table 1,
[tex]\frac{y_1}{x_1}=\frac{8}{4}=\frac{2}{1}[/tex]
[tex]\frac{y_2}{x_2}=\frac{11}{7}[/tex]
[tex]\frac{2}{1}\neq \frac{11}{7}[/tex]
Table 1 does not represents a proportional relationship.
Similarly,
For table 2,
[tex]\frac{25}{5}\neq \frac{49}{7}[/tex]
Table 2 does not represents a proportional relationship.
For table 3,
[tex]\frac{3}{6}=\frac{5}{10}=\frac{7}{14}=\frac{1}{2}[/tex]
Table 3 represents a proportional relationship.
For table 4,
[tex]\frac{6}{3}\neq \frac{11}{8}[/tex]
Table 4 does not represents a proportional relationship.
Only table 3 represents a proportional relationship. Therefore the correct option is 3.
Use the substitution method to solve the system of equations. Choose the correct ordered pair. 2x + y= 8 and y= -x + 5
Answer:
The ordered pair is (3, 2).
Step-by-step explanation:
y = -x + 5
2x + y = 8
Substitute y = -x + 5 in the second equation:
2x + (-x + 5) = 8
x + 5 = 8
x = 3.

G. -10
Step-by-step explanation:
Let one number = x
Let the second one = y
Equations
y = 5x
x + y = -60
Solution.
Put 5x in for y in the second equation.
x + 5x = -60 Combine like terms on the left
6x = -60 Divide by 6
6x/6 = -60/6 Do the division
x = -10

The digits 1,2,3 and 4 are used to make a 3 digit number. Each digit can be repeated. What is the total number of 3 digit numbers that can be made using these digits?
Answer:
24 ways
Step-by-step explanation:
4P3 = 4*3*2
=24
Final answer:
The total number of three-digit numbers that can be made using the digits 1, 2, 3, and 4 with repetition allowed is 64. This is computed by multiplying the number of digit options available for each place value in a three-digit number (4 options each for hundreds, tens, and ones).
Explanation:
To determine the number of possible three-digit numbers that can be created using the digits 1, 2, 3, and 4, with the possibility of repeating digits, we need to consider that each place value (hundreds, tens, and ones) can be filled by any of the four digits available.
Therefore, for the hundreds place, there are 4 options (1, 2, 3, or 4). The same is true for the tens and ones place, since repetition is allowed, giving 4 options for each. We calculate the total number of combinations by multiplying the number of options for each place value:
Hundreds place: 4 options
Tens place: 4 options
Ones place: 4 options
The total number of possible numbers is 4 (for the hundreds) × 4 (for the tens) × 4 (for the ones) = 64 numbers.

In an '80% off' sale, an oven was £112. Work out the original price.
Answer:520
Step-by-step explanation:
Suppose the original prize is=x
If the discount is of 80%,the selling prize is of 20%
20% of x=112
20x/100=112
X=520
Its the original prize...
Answer:
£560
Step-by-step explanation:
80% off means that the sale price is 20% of the original price.
The original price is represented by 100%
Divide the sale price by 20 to find 1% then multiply by 100 to obtain the original price
original price = [tex]\frac{112}{20}[/tex] × 100 = £560

Vanesa earns a base salary of $400.00 every week with an additional 5% commission on everything she sells. Vanessa sold $1650.00 worth of items last week.
What was Vanessa’s total pay last week?
Answer:
$482.50
Step-by-step explanation:
x=1650×5/100
x=16.5×5
x=82.50
400+82.5=482.5
Answer:
482.50
Step-by-step explanation:
Her base is 400. If she sells nothing, that's her take home.
Take home = 400 + 5% of what she sells.
Take home = 400 + (5/100) * 1650
Take home = 400 + (0.05) * 1650
Take home = 400 + 82.50
Take home = 482.50

If you have an average 90. Give two numbers other than 90 that would make the average 90
Answer:
The numbers 180 and 0 would make the average 90
Step-by-step explanation:
we know that
To find the average of two numbers, add the numbers and then divide by two.
Let
x ----> one number
y ----> the other number
The average is equal to
(x+y)/2
For x=180 and y=0
the average is equal to
(180+0)/2=90
therefore
The numbers 180 and 0 would make the average 90
Lin multiplies 7/8 times a number.the product is less than 7/8 . Which could be Lin’s number ?
Answer:
Any number less than 1
Step-by-step explanation:
Let x be the number Lin multiplies by 7/8. So, we have:
(7/8)*x < 7/8
We need to find the possible values for x. Lets start by dividing both sides of our inequality by (7/8) in order to get x alone on the left side.
(7/8)*x / (7/8) < (7/8)/(7/8)
Reordering:
(7/8) / (7/8) * x < (7/8)/(7/8)
As any number divided by itself (except from 0) is equal to 1:
x < 1
So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.
So, such number is less than 1. Any number less than 1 could be Lin's number.

the national flag of scotland has a white diagonal on a blue backround Tracy is sewing a scottish flag she knows that the length of one diagonal will be 15 feet and the flag will be 9 feet high to the nearest foot how long will the scottish flag be
Answer:
12 feet
Step-by-step explanation:
By Pythagoras theorem, a²+b²=c², where c represents the diagonal and a and b represents the other sides of a right angled triangle
As a flag is a rectangle, the two triangles cut would be right angled triangles
Therefore, a²+9²=15²
a²+81=225
a²=144
a=√144
a=12 feet
Final answer:
To calculate the length of the Scottish flag, the Pythagorean theorem is applied. With a diagonal (hypotenuse) of 15 feet and a height of 9 feet, the length is found to be 12 feet.
Explanation:
The question involves calculating the length of the Scottish flag given the length of one diagonal and the flag's height. To find the length of the Scottish flag, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Here, we know the length of the diagonal (hypotenuse) is 15 feet and the height (one side) is 9 feet.
Let x be the length of the Scottish flag (the other side of the right-angled triangle). According to the Pythagorean theorem, [tex]x^2 + 9^2 = 15^2.[/tex]
Solving for x, we get:
[tex]x^2 + 81 = 225[/tex][tex]x^2 = 225 - 81[/tex][tex]x^2 = 144[/tex][tex]x = \sqrt144[/tex]x = 12Therefore, the length of the Scottish flag will be 12 feet to the nearest foot.

the set of ordered pairs represented by the graph below can be described as which of the following
a relation only
a function only
both a relation and function
neither a relation or function
ANSWER
a relation only
EXPLANATION
The given graph shown in the attachment represents only a relation and not a function.
The reason is that, a vertical line drawn across this graph will intersect this graph at more than one point.
Since the graph fails to pass the vertical line test, the ordered pair represented by this graph represents a relation only.
Answer: First option.
Step-by-step explanation:
By definition, a relation is a function if each input value (value of "x") has only one output value (value of "y").
In the figure you can observe that each x-coordinate has more than one y-coordinate. Then, since each input value (value of "x") does not have only one output value (value of "y"), you can say that it is not a function, but a relation only.
Therefore, the conclusion is:
The set of ordered pairs represented by the graph, can be described as a relation only.
