Answer:
50 miles
Step-by-step explanation:
60 divided by 30 = 5
5 miles = 10% of the trip
40% of the trip left to go
40% = 20 miles (5 x 4)
30 + 20 = 50
hope this helps!
To find the length of the whole trip, set up a proportion using the given information and solve for the missing variable. The whole trip is approximately 50 miles long.
Explanation:To find the length of the whole trip, we can set up a proportion using the information given. We know that 60% of the trip is equivalent to 30 miles. We can set up the proportion:
60% / 100% = 30 miles / x
By cross-multiplying, we get:
x = (30 miles * 100%) / 60%
Calculating this, we find that the whole trip is approximately 50 miles long.

A student has gotten the following grades on his tests. What is the minimum grade he must get on the last test in order to have an average of 82? 85, 90, 79, 72
Answer:
84
Step-by-step explanation:
Because average is basically the mean, so i used a mean calculator and put in the four grades (numbers) and got an average of 81.5, so then i kept putting an additional other number in and wasn't getting 82, until i put in 84 and all of those numbers together gave me an average of 82.
Answer:
84
Step-by-step explanation:
The average is found by adding all the scores together and dividing by the number of scores
Let the unknown score be x
(85+90+79+72+x) /5 = 82
Multiply each side by 5
(85+90+79+72+x) /5*5 = 82*5
(85+90+79+72+x) = 410
Combine like terms
326+x = 410
Subtract 326 from each side
326+x-326 = 410 -326
x =84

Can you answer these questions? Im doing them on my own but I need to check if they're right
Answer:
I got you.
Step-by-step explanation:
1. If x=5, whats (10x-5)+30:
First, (10x-5)
50-5=45
45+30=75
10x-5+30=75.
2.Inverse operations: 10+5 inverses 10-5, 10*5 inverses 10/5
3. I do: For example: 10x-5=60
Then, you would divide: 60/10 and 10/10
We need to isolate the variable: x-5=6
Leaving x to be 11.
4. That is a hard one but, for an equation to have no solution is that it is impossible to answer or just doesn't have an answer. And for an equation to have infinite solutions it means that it has more than one answer... Infinitely.
5. Using the distributive property for simplify: The distributive property of multiplication is a very useful property that lets you simplify expressions in which you are multiplying a number by a sum or difference. The property states that the product of a sum or difference, such as 6(5 – 2), is equal to the sum or difference of the products – in this case, 6(5) – 6(2).Remember that there are several ways to write multiplication. 3 x 6 = 3(6) = 3 • 3 • (2 + 4) = 3 • 6 = 18.
Is y=x a proportional linear equation
Answer: yes.
Step-by-step explanation:
Graph the equation
y=2(x+1)(x-1)
To graph the equation y = 2(x+1)(x-1), we can start by finding the x-intercepts and y-intercept of the equation.
To find the x-intercepts, we set y = 0 and solve for x:
0 = 2(x+1)(x-1)
0 = 2(x^2 - 1)
0 = 2(x+1)(x-1)
So, the x-intercepts are -1 and 1.
To find the y-intercept, we set x = 0 and solve for y:
y = 2(0+1)(0-1)
y = -2
So, the y-intercept is -2.
Now, we can plot the intercepts on the coordinate plane and sketch the graph of the equation. Since the equation is a quadratic function, the graph will be a parabola.
The x-intercepts are -1 and 1, so we can plot these points on the x-axis. The y-intercept is -2, so we can plot this point on the y-axis.
Next, we can plot a few additional points to help us sketch the graph. For example, we can choose x = -2, -0.5, 0.5, and 2, and find the corresponding y-values:
When x = -2, y = 2(-2+1)(-2-1) = 6
When x = -0.5, y = 2(-0.5+1)(-0.5-1) = 1.5
When x = 0.5, y = 2(0.5+1)(0.5-1) = -1.5
When x = 2, y = 2(2+1)(2-1) = 6
Now, we can plot these points and sketch the graph of the equation, which is a parabola that opens upwards and passes through the points (-2, 6), (-1, 0), (0, -2), (1, 0), and (2, 6).
The graph of the equation y = 2(x+1)(x-1) is shown below:
Graph of y = 2(x+1)(x-1)
Therefore, this is the graph of the equation y = 2(x+1)(x-1).
Look at this check register. Calculate the current balance.
A check register has a balance of 82 dollars and 92 cents. 78 dollars and 24 cents is debited for a phone bill. 125 dollars is deposited for a pay check. 40 dollars is debited from the A T M. 56 dollars and 50 cents is debited for tennis lessons.
The current balance is $
.
Answer:
$33.18
Step-by-step explanation:
$33.18 is the answer because...
Step one first we have the money in the cash register of $82.92. Unfortunately she has to pay a phone bill of $78.24 so we subtract 82.92 and 78.24 which leaves the person with $4.68.Step two so she has $4.68 but now she gets an outstanding $125 paycheck. So we add $4.68 and $125 to get $129.68 as her new balance.Now the person's balance is $129.68 it says in the question she debited $40 from the ATM. So we subtract $129.68 and $40 to get $89.68.Step four she also had to pay $56.50 for the persons tennis lessons so we subtract $89.68 and $56.50 to get our final answer of $33.18Hope this helped :)The current balance is calculated by starting with the initial balance of $82.92 and then subtracting debits and adding credits from various transactions. After all adjustments, the current account balance is $33.18.
To calculate the current balance, we'll start with the first number under Balance and adjust it based on the recorded transactions.
Start with the initial balance: $82.92
Subtract the debit for the phone bill: $82.92 - $78.24 = $4.68
Add the deposit from the paycheck: $4.68 + $125.00 = $129.68
Subtract the ATM debit: $129.68 - $40.00 = $89.68
Finally, subtract the debit for tennis lessons: $89.68 - $56.50 = $33.18
Therefore, the current balance is $33.18.

(x, y) --> (-x , y)
(x, y) --> (x , y + 8)
(x, y) --> (-y , x)
(x, y) --> (x , -y)
Answer: (x, y) —> (-x, y)
Step-by-step explanation:
This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)
(x, y) --> (-x , y)
Step-by-step explanation:
When reflecting across the y-axis, you will want to switch the sign of the x-coordinate. If the x-coordinate is positive, you will want to switch it to negative and vice versa.
Examples:
(3,5) --> (-3,5)
(-6,-2) --> (6,-2)

On a certain hot summer's day, 163 people used the public swimming pool. The daily prices are $ 1.50 for children and $ 2.50 for adults. The receipts for admission totaled $ 312.50 . How many children and how many adults swam at the public pool that day?
Answer: 95 children, 68 adults
Step-by-step explanation:
Let the number of children be y
Let the number of adults be z
The following equation can be gotten from the question:
y + z = 163 ...... equation i
1.5y + 2.5z = 312.5 ....... equation ii
Multiply equation I by 1.5
Multiply equation ii by 1
1.5y + 1.5z = 244.5 ......... equation iii
1.5y + 2.5z = 312.5 ........ equation iv
Then subtract equation iv from iii
-z = -68
z = 68
From equation I
y + z = 163
y = 163 - 68
= 95
95 children and 68 adults swam.

Given PQ | | ST
Triangle P Q R. Side P Q is 16 kilometers and side P R is 24 kilometers. Triangle S R T. Side R T is 33 kilometers.
What is the distance of Line S T?
7 km
StartFraction 128 Over 11 EndFraction km
22 km
49.5 km
The answer is C = 22km
Final answer:
To determine the distance of line ST, we use the fact that triangles PQR and SRT are similar, which allows us to set up a proportion with the given side lengths. Solving this proportion reveals that the length of ST is 22 kilometers.
Explanation:
To find the distance of line ST, we need to recognize that if lines PQ and ST are parallel (PQ | | ST) and we are given the lengths of the sides PQ and PR in triangle PQR and side RT in triangle SRT, we can infer that triangles PQR and SRT are similar by the Angle-Side-Angle (ASA) postulate since they share angle P (or R in triangle SRT) and have proportional corresponding sides.
Using the lengths PQ = 16 kilometers and PR = 24 kilometers from triangle PQR and RT = 33 kilometers from triangle SRT, we can set up a proportion to solve for the unknown length ST.
The proportion based on the similarity of triangles is:
PQ/PR = ST/RT
Substituting the given values, we get:
16/24 = ST/33
Solving for ST, we multiply both sides by 33:
ST = 33 * (16/24) = 22 kilometers.
Therefore, the distance of line ST is 22 kilometers.

A. an = 6n - 8
B. an = -8n + 6
C. an = 8n - 6
D. an = -6n + 8
Answer:
D
Step-by-step explanation:
The terms in the sequence have a common difference d between consecutive terms, that is
d = - 4 - 2 = - 10 - ( - 4) = - 16 - (- 10) = - 22 - (- 16) = - 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
