Answer:
A
Step-by-step explanation:
multiply $17.95 by 40% to get the discount ($17.95 x .4), which equals $7.18.
the sale price is the initial price of the book less the discount ($17.95-$7.18), which equals $10.77.
Estimate, and then find the quotient. Use your estimate to check for reasonableness. 9,157÷32
Answer:
9,157 divided by 32=286.15625
9,157 rounded is 9.000
32 rounded is 30
9,000 divided by 30 equals the quotient of 300
our original answer 286, would round up to 300

may 3rd -> july 15th = 73 days
500*0.06 = 30
30 = how much he makes in one day (so he has 530 after 1 day)
30*73 = 2190
500 + 2190 = 2690
9.
210/7 = 30
1% for 3 years = 30
1% for 1 year = 10
100% for 1 year = 1000
2000*0.06 = 120
11.
54,000*0.08 = 4320
54,000/4320 = 12.5

will someone please tell me what I got correct and what I got incorrect
Answer:
all correct
Step-by-step explanation:
Answer:
What you got right:
0.5 - Possible
48 - Possible
-6 - Not possible
0 - Not possible
BUT....
3 is possible
Step-by-step explanation:
When we want to know the side lengths of a rectangle and we have possible choices, we want to look at if it's in the realm of possibility. That is, if it's physically possible. You have 5/6 correct, so I think you've done a good job so far. But what you got wrong was the statement that 3 is not possible.
3 is possible, because 24 is divisible by 3. The length would then be 8. So, what you should have put is that 3 is Possible.
(my comment on someone else's answer is incorrect, you only got one wrong, my bad)

Solve for J MUST SHOW WORK
j/-2 + 7 = -12
thx!!
Answer:
j=38
Step-by-step explanation:
j/-2 +7=-12, subtract 7 from both sides of the equation and you get j/-2 = -19, then you multiply j/-2 by -2/1 and multiply -19 by -2/1 to get j= 38

Step-by-step explanation:
state whether the following statement is true or false: y= -x2 + 6x - 10 does not intersect the x-axis.
Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis
A car dealership sold 236 car in 4 months. At what rate did the dealership sell cars in per month ?
Using a starting position p, a speed s, and a time t, write two expressions for an ending position. One expression should show the result of moving right, and one expression should show the result of moving left.
going right:
going left:
Answer:
Step-by-step explanation:
We can use signed numbers to represent the position of an object along a line. We pick a point to be the reference point, and call it zero. Positions to the right of zero are positive. Positions to the left of zero are negative.
When we combine speed with direction indicated by the sign of the number, it is called velocity. For example, if you are moving 5 meters per second to the right, then your velocity is +5 meters per second. If you are moving 5 meters per second to the left, then your velocity is -5 meters per second.
If you start at zero and move 5 meters per second for 10 seconds, you will be 5⋅10=50 meters to the right of zero. In other words, 5⋅10=50 .
If you start at zero and move -5 meters per second for 10 seconds, you will be 5⋅10=50 meters to the left of zero. In other words,
−5⋅10=−50
In general, a negative number times a positive number is a negative number.

You're going on a 1211-mile trip, and your car gets about 29 miles per gallon. Gas prices along your route average $3.40. Estimate the cost of gasoline for this trip by rounding the distance to 1200 miles, the mileage to 30 miles per gallon, and the cost of gas to $3.00 per gallon. Calculate the answer without using estimate and compare the two results. (Round your answers to the nearest cent.)
Answer:
Using the estimate:
The car has to go for 1,200 miles but it consumes a gallon of gasoline for every 30 miles. The number of gallons it will need is therefore:
= 1,200 / 30
= 40 gallons
Each gallon costs $3.00 so the total cost is:
= 40 * 3
= $120
Without using the estimate:
The car has to go for 1,211 miles but it consumes a gallon of gasoline for every 29 miles. The number of gallons it will need is therefore:
= 1,211 / 29
= 41.76 gallons
Each gallon costs $3.40 so the total cost is:
= 41.76 * 3.40
= $141.98
Using the estimate provides a lower cost of gasoline for the trip.

Show that the quadrilateral is a parallelogram.
9514 1404 393
Answer:
opposite sides have the same slope, so it is a parallelogram
Step-by-step explanation:
A parallelogram has opposite sides that are parallel. Here, one pair of opposite sides consists of horizontal lines. Both have zero slope, so are parallel.
The other pair of lines each has a "rise" of 3 units for each "run" of 2 units, so the lines have a slope of 3/2. Both lines have the same slope, so are parallel.
Since opposite sides are parallel, the figure is a parallelogram.
