Madeline bought a hybrid car that averages 46 miles per gallon. How much gas will she need for a 350-mile trip? Select the equation and the solution (2 answers).
Group of answer choices
350 x 46 = n
46n = 350
approximately 7.61 gallons
approximately 8.75 gallons
Answer:
46n = 350approximately 7.61 gallonsStep-by-step explanation:
1 gallon = 46 miles
350 miles = 350 ÷ 46
46n = 350=7.60869565217 gallons
approximately 7.61 gallonsthe length of a rectangle is 3 m longer than it’s width. if the perimeter of the rectangle is 58 m, find its length and width
Answer:
length is 16m
width is 13m
Step-by-step explanation:
width, w =?
length, l = 3+ w
perimeter =2(l+w)
58=2[(3+w) +w]
29=3+2w
26=2w
w=13
l= 16
For every 15 bicycles seen in Harlem, there were 60 cars. How many cars will we need for 33 bicycles?
Answer:
132 bicycles
Step-by-step explanation:
The ratio of bicycles to cars is 15:60. Before anything, we need to simplify this ratio. 15/15 = 1, and 60/15 = 4. So, now we have 1:4. Since the question asks for 33 bicycles, we multiply the number of bicycles, 1, by 33. Since we are multiplying the bicycles, we also need to multiply the cars. 4 x 33 = 132.
33:132. We need 132 cars.
Theo is driving with his mom to Paso Robles. It took Theo 4 hours to drive 228 miles. Lex drove with his dad to San Luis Obispo. Lex drove 186 miles in 3 hours. a. How far does Theo drive in 1 hour? How far does Lex drive in 1 hour? b. Who drove faster? Explain how you know.
Answer:
A. Theo drove 57 miles and Lex drove 62 miles in 1 hour.
B. Lex drove faster. We know this because in order to figure out how many miles each drove per hour you need to find there individual rate. Which is 228/4 and 186/3. You want to divide using the hours so you generate a response where 1 hour is the only thing left. Thus giving you mph (miles per hour). Lex is drove 5 miles more in an hour than Theo leading us back to who drove faster. Lex did.

Bridget, Cassie, and Hannah are discussing the results of their last math test. Hannah shows Bridget and Cassie her test, but Bridget and Cassie don't show theirs to anyone. Cassie says, 'I didn't get the lowest score in our class,' and Bridget adds, 'I didn't get the highest score.' What is the ranking of the three girls from highest to lowest?
Answer:
Based on this I would say Cassie got the highest, then Hannah, then Bridget.
Step-by-step explanation:
Cassie saying that she didn’t get the lowest means that her’s is higher than Hannah’s. The Bridget saying that she didn’t get the highest probably means she got lower than Hannah.
━━━━━━━☆☆━━━━━━━━━━━━━━☆☆━━━━━━━
《Answer》
If Hannah did better than Cassie, there would be no way she could know for sure that she didn't get the lowest score in the class. Therefore, Hannah did worse than Cassie. Similarly, if Hannah did worse than Bridget, there is no way Bridget could have known that she didn't get the highest in the class. Therefore, Hannah did better than Bridget, so our order is
Cassie, Hannah, Bridget

The sum of two numbers is -32. One number is 2 less than the other.
The numbers whose sum is negative 32 will be negative 15 and negative 17.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The sum of the two numbers is -32. One number is 2 less than the other.
Let the two numbers be x and y. Then the equation is given as,
x + y = - 32 ...1
x = y - 2 ...2
From equations 1 and 2, then the value of y will be
y - 2 + y = - 32
2y = - 30
y = - 15
Then the value of x will be given as,
x - 15 = - 32
x = - 17
The numbers whose sum is negative 32 will be negative 15 and negative 17.

Guys what is the definition of consecutive numbers? Anyone know? 20 points for first answer!!
They are integers that follow one right after another. For example the set {1,2,3,4,5} represents consecutive numbers. Another example would be {9,10,11,12,13}
In general, if x is some integer, then x+1 is the next integer right after x, and x+2 is right after x+1 and so on. The list is {x, x+1, x+2, x+3, ...} representing any general set of consecutive numbers.

inverse of the letter a
Answer:
We have the function f(x) = 2x + 3
the processes which take place in this function are
we take x [x]
we multiply it by 2 [2x]
we add 3 to it [2x + 3]
To get the inverse of this function, we will do exactly the opposite of it
we will take the output of the initial function [y]
we will subtract 3 from it [y-3]
we will divide it by 2 [(y-3)/2]
We get the function:
[tex]f^{-1}[/tex](y) = (y-3) / 2
Inverse functions are used to get the initial value used in the function bu using the output of the function
[tex]f^{-1}[/tex](0) = (0-3)/2
[tex]f^{-1}[/tex](0) = -3/2
Therefore, the input of the function is -3/2 when the output is 0

Question 4! Need help
A college cafeteria pays student cashiers $7.70 per hour. Cashiers earn an additional $1.70
per hour for each hour worked over 35 hours per week. A cashier worked 41 hours one
week and 39 hours the second week. How much did this cashier earn in this two-week
period?
Answer:
$633
Step-by-step explanation:
Overtime:
(41 - 35 + 39 - 35) hours = 10 hours
Overtime rate: ($7.70 + $1.70)/hour = $9.40/hour
Regular time:
(35 + 35) hours = 70 hours
Regular rate: $7.70/hour
total pay = regular pay + overtime pay
total pay = $7.70/hour × 70 hours + $9.40/hour × 10 hours
total pay = $633

Find the 48th term.
The sequence 5,12, 19, ... is an arithmetic sequence
The 48th term is 334
How to determine the 48th term?The sequence is given as:
5,12, 19, ...
The above sequence is an arithmetic sequence with the following parameters:
First term (a) = 5
Common difference (d) = 7
The nth term of an arithmetic sequence is:
Tn = a + (n - 1) * d

What is the equation of a line parallel to y=7x-8 that passes through (5, -2)?
Answer:
The required line is Parallel to y = 7x - 8
This means their slopes are equal
So m = 7
Now writing the equation of straight line,
[y - (-2)] = m(x - 5)
y + 2 = 7(x - 5)
y + 2 = 7x - 35
7x - y - 37 = 0
