Answer:
186
Step-by-step explanation:
248÷8 = 31
31 miles = 1 hour
31×6 = 186
Answer:
186 miles in 6 hours.
Step-by-step explanation:
Since the problem gives 248m/8h, you would divide 8 into 248 to get the constant speed of 31mph. If you multiple 31 by 6, you get 186 miles after 6 hours.

What is the domain and range for the function graphed to
the left?
Answer:
Domain: (-∞, ∞)
Range: (-∞, -3]
General Formulas and Concepts:
Algebra I
Domain is the set of x-values that can be inputted into function f(x)Range is the set of y-values that are outputted by function f(x)Step-by-step explanation:
We know that the parabola will continue indefinitely, hence we use infinity. Our domain would then be from negative infinity to positive infinity, because we can plug in any number x.
We see the from the graph that the y-value is actually restricted. We have a max value of y = -3, and the graph will never go higher than that. Therefore, our range spans from negative infinity to -3.
Step-by-step explanation: The range of a function
is the set of all y values of the function.
The y values on a coordinate system are the up and down values.
Our parabola is expanding infinitely downwards but
it never goes above the y value of -3.
So we say that the range of this function is {y: y ≤ -3}.
The domain is the set of all x values or left and right values.
Since it's expanding infinitely to the left and right,
we say that the domain is the set of all real numbers or R.

Tom woke up one morning and the temperature was −6° Celsius. The high temperature that day was 6° Celsius. What was the difference between the low temperature and the high temperature that day?
Answer:
12˚C
Step-by-step explanation:
If the high temperature is 6˚ and the low temperature is -6˚, the difference is
6˚-(-6˚)
=6˚+6˚
=12˚.
Zuri quickly solved the problem and told her team, "Hey! I go it m\large \angleA = 93°, m\large \angleB = 63°, m\large \angleC = 36°. Done!" Mikaya and Olivia are suspicious. Does Zuri have the correct answer, or are Mikaya and Olivia correct to be suspicious? Explain completely. Be clear, specific, and detailed.
Answer:
Mikaya and Olivia are correct to be suspicious
Step-by-step explanation:
Sum of the angles of a triangle is always 180
But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180
So, Zuri is wrong

Write a piecewise function for the graph.
Similar to Modulus, but It's separated.
Since both are separated, that means - they are both linear function.
The range is greater than all negative numbers. That means y ≥ 0
( 1 ) For the blue graph,
y = -x-3 {y ≥ 0} ---------- Blue Graph Answer
-x-3=0
-x=3
x=-3
We can clearly see that the slope is -1.
And intercept x-axis at (-3,0)
( 2 ) For the red graph.
y = 2x+6 { y ≥ 0} ---------- Red Graph Answer
Notice that the slope is 2.
And intercept x-axis at (-3,0)
Also intercept y-axis at (0,6)
2x+6=0
2x=-6
x=-3
---------- Only linear function with given y ≥ 0 can draw that. (Only separated graph.) --------------

I have 5 digits. My q is worth q * 10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am l
Answer:
92,776
Step-by-step explanation:
I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?
My 9 is worth 9*10,000 = 9 * 10,000
= 90,000
My 2 is worth 2 thousand = 2,000
One of my 7s is worth 70 = 70
The other is worth 10 times as much = 70 * 10
= 700
My other digit is a 6 = 6
The number is
90,000 + 2,000 + 700 + 70 + 6
= 92,776

A retail store is having a sale on toilet paper. At 2:00 PM, the
store had sold a total of 15 packs of toilet paper. At 5:00 PM,
the store had sold a total of 57 packs.
Assuming that it is positive, what is the average rate of change
between 2:00 PM and 5:00 PM?
Answer:
14.25 packs per hour
Step-by-step explanation:
it is 4 hours from 2:00-5:00 so... 57÷4=14.25 packs per hour
The average rate of change between 2:00 PM and 5:00 PM will be 14 packs per hour.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables. The term "rate of change" refers to the pace at which one quantity changes with respect to another.
Given that, a retailer is offering discounted toilet paper. The shop sold a total of 15 packs of toilet paper around 2:00 PM. The shop has sold 57 packets as of 5:00 PM.
The average rate of change between 2:00 PM and 5:00 PM is obtained by taking the ratio of the change to the number of packs sold to the time elapsed as,
=( 57 - 15 ) / 5 - 2
=42 / 3
= 14 packs per hour.
Thus, the average rate of change between 2:00 PM and 5:00 PM will be 14 packs per hour.

Solve the following equation for x.
5/8x +4 = 3/8x +12
Answer:
x=32
Step-by-step explanation:
8(5/8x+4 = 3/8x+12)
5x+32=3x+96
2x+32=96
2x=64
x=32
Answer:
x = 32
Step-by-step explanation:
5/8x + 4 = 3/8x + 12
subtract 3/8 from both sides
2/8x + 4 = 12
simplify
1/4x + 4 = 12
subtract 4 from both sides
1/4x = 8
multiply each side by the reciprocal of 1/4
4/1 • 1/4x = 8 • 4/1
solve
x = 32

Given that a = -1, b=2 and c= -3 ,find the value of a(b2+c2)
Answer:
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a([tex]b^{2}[/tex]+[tex]c^{2}[/tex])
Just substitute the values given for each variable
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = (-1)([tex]2^{2}[/tex]+[tex](-3)^{2}[/tex]) ; do the exponents first
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = -13 ; and multiply by -1
