The Sugar Sweet Company is going to transport its sugar to market. It will cost to rent trucks, and it will cost an additional for each ton of sugar transported. Let represent the total cost (in dollars), and let represent the amount of sugar (in tons) transported. Write an equation relating to . Then use this equation to find the total cost to transport tons of sugar.
Answer:
C(11) = 9975
Step-by-step explanation:
Let C represent the total cost (in dollars),
and let S represent the amount of sugar (in tons) transported
equation:
C(s) = 225s + 7500
find the total cost to transport 11 tons of sugar.
C(11) = 225(11) + 7500
C(11) = 2475 + 7500
C(11) = 9975

a mechanic repairs mr. estes' car. the amount for parts is $48.00 and the rate for the mechanic is $40.00 per hour. write and solve an equation to find the total cost of repairs to mr. estes' car if the mechanic works for 1.5 hours
Step-by-step explanation:
Total cost of repairs = the amount for parts + (40 × repair hours)
the amount of parts = y
the hours = x
Total cost = y + 40x
= 48 + (40 × 1.5)
= 48 + 60 = 108 $
5(w + 4 x 10^3)= 6 x 10^4
Answer:
w = 8000
Step-by-step explanation:
5(w+4*10^3) = 6(10^4)
5(w+4*1000) = 6(10000)
5(w+4000) = 60000
5w + 20000 = 60000
5w = 40000
w = 8000

Find the value of x and y
Answer:
x = 10 and y = 15
Step-by-step explanation:
The arrows on lines AB and CD indicate that they are parallel. This means that we have to look for Z-angles (I don't know if they are called the same where you're from but I hope you recognise the term). This means that ∠ABC = ∠BCD
5x - 20° = x + 20°
4x = 40°
x = 10°, which gives us the first answer.
The angle formed by points ACE (a straight line) is 180 degrees. Lets refer to this as angle ACE. We also know this angle consists of angle ACB, BCD and DCE. This gives us the following equation:
angle ACE = angle ACB + x + 20° + y + 20° = 180°
angle ACB + x + y + 40° = 180°
angle ACB = -x - y + 140°
Inserting the x we found earlier this gives
∠ACB = - y + 130°
Now we can find a second equation to describe ACB by looking at the triangle it is inside. The angles in a triangle always add up to 180°, giving the following expression:
4y - 25° + 5x - 20° + ∠ACB = 180°
Substituting x again gives
4y - 25° + 50° - 20° + ACB = 180°
ACB = 180 - 4y - 5° = 175° -4y
Combining the two expressions for ACB gives the final equation to solve:
175° - 4y = -y + 130°
-3y = -45
y = 15

Kennedy has a bag that contains strawberry chews, apple chews, and lime chews. She
performs an experiment. Kennedy randomly removes a chew from the bag, records
the result, and returns the chew to the bag. Kennedy performs the experiment 38
times. The results are shown below:
A strawberry chew was selected 18 times.
A apple chew was selected 11 times.
A lime chew was selected 9 times.
Based on these results, express the probability that the next chew Kennedy removes
from the bag will be a flavor other than apple as a decimal to the nearest hundredth.
Answer:
0.71
Step-by-step explanation:
Based on what we see here, we can deterime the probability of each flavor being drawn.
Apple: 11/38
Strawberry: 18/38
Lime: 9/38
So the probability of an apple NOT being drawn is 27/38. This is about 0.71.

Rewrite the equation in slope-intercept form. Then identify the slope and the y intercept of the line
4x + y = 1
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x + y = 1 ( subtract 4x from both sides )
y = - 4x + 1 ← in slope- intercept form
with slope m = - 4 and y- intercept c = 1

Alyssa bought 2 packs of football cards for $4.52 each, and a deck of Digimon cards

40-20.51= 19.49 before change in pocket
+7.72 =27.21 post change in pocket
Hello :D
2 x $4.52 = $9.04
$9.04 + $11.47 = $20.51
2 x $20 = $40.00
$40.00 - $20.51 = $19.49
With change:
$40.00 + $7.72 = $47.72
$47.72 - $20.51 = $27.21
9. A teacher places seven cards, lettered A-G, on
a table. Which cards show irrational
numbers?
Answer:
Cards C and E
Step-by-step explanation:
Remember that irrational numbers cannot be written as a fraction of two integers:
Is 10 irrational? No, because 10 can be written as a fraction (ex. 10/1, 20/2, etc.)
Is 6/5 irrational? No, because it is a fraction.
Is π irrational? Yes, because it can't be written as a fraction as its digits continue infinitely without repetition.
Is 11/4 irrational? No, because it is a fraction.
Is 8.25635... irrational? Yes, because the ellipsis shows the digits continue infinitely without repetition, otherwise there would be a bar over the digits to show repetition
Is -7 irrational? No, because it can be written as a fraction (ex. -7/1, -14/2, etc.)
Is 6.31(bar) irrational? No, because the bar shows that the digits 3 and 1 repeat.
Therefore, only cards C and E are irrational.
The cards that represent irrational numbers are C (π) and possibly E (8.25635), as π is a well-known irrational number and E is a decimal with multiple digits. The other options represent rational numbers.\
The cards that show irrational numbers are:
C. π (pi) - π is an irrational number representing the ratio of a circle's circumference to its diameter.
E. 8.25635 - This number is not known to be irrational based on the given information, but as it is a decimal with multiple digits, it could potentially be irrational.
The other options, A, B, D, F, and G, represent rational numbers, either whole numbers or fractions, and are not considered irrational.

if you make $391 for 17 hours how much would you make in 13 hours
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.

[tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1
Step-by-step explanation:
By subtracting x³ - 3x² + x - 1 , that is
[tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - (x³ - 3x² + x - 1) ← distribute by - 1
= [tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - x³ + 3x² - x + 1 ← collect like terms
= [tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1
Step-by-step explanation:
x⁴ + 5x³ - 6x² - 5x - 2
should become
x³ - 3x² + x -1
so, what do I need to subtract from the top terms to get the bottom terms ?
because we can only look from one x- term to the next. we can only combine them, when they have the same x exponent.
so, we see there is no x⁴ in the desired result.
therefore, we know as a first item that x⁴ had to be subtracted.
the next x exponent is 3.
we have 5x³ on the top, and x³ on the bottom.
so, clearly, we need to subtract 4x³ as second term.
the next x exponent is 2.
we have -6x² on the top, and -3x² on the bottom.
so, we should actually add 3x². and how do we do this in a subtraction ? by subtracting a negative value, which actual adds it.
so, we need to subtract -3x² as third term.
the next x exponent is 1 (just x).
we have -5x on the top and x on the bottom.
so, the same trick as before, as we need to add something.
so, we need to subtract -6x as fourth term.
and finally, the x exponent 0, which just shows the constant numbers.
we have -2 on the top and -1 on the bottom.
again the same trick to actually add 1.
we need to subtract -1 as fifth term.
so, in total, this is what we need to subtract from the top line to get the bottom line :
x⁴ + 4x³ - 3x² - 6x - 1
