Answer:
proportional
Step-by-step explanation:
so if 1/2 is 20, 1/4 is 10, and 1 whole mile is 40.
40 + 40 + 40 + 10 + 10 + 10 = 150
because we used the reasoning from the first part and it turned out correct, it is proportional
A saleswoman earns 20% commission on all the merchandise that she sells. Last month she sold $400 worth of merchandise. How much commission (in dollars) did she earn last month
Answer:
$80 in commission

Find her commission by multiplying 400 by 0.2:
400(0.2)
= 80
So, last month, she earned $80 in commission
Jemima filled one fourth of a barrel with compost on Saturday. Then she filled the remaining space with 4,200g of compost on Sunday. How many kilograms of compost are in the barrel
Answer: 5.6kg
Step-by-step explanation:
Since Jemima filled one fourth of a barrel with compost on Saturday, then the remaining space will be:
= 1 - ¼ = ¾
Since the remaining ¾ space is filled with 4200g of compost, then the compost in the barrel will be
¾ × x = 4200g
0.75 × x = 4200g
0.75x = 4200g
x = 4200g/0.75
x = 5600g
Since 1000g = 1kg
5600g = 5600/1000 = 5.6kg
There is 5.6kg of compost in the barrel.

HELP ASAP!!! Identify the factored form of each polynomial
Answer:
9x2 +42x + 24 is (x + 4) (9x + 6)
9x2 + 30x + 24 is (3x + 6) (3x + 4)
9x2 + 58x + 24 is (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)

Find the distance between the pair of points.
(2, -2), (-5, -2
Answer:
7
Step-by-step explanation:
Answer:
7 units
Step-by-step explanation:
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Plug in what you know.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 - (-2))^2 }[/tex]
Evaluate the double negative.
[tex]d = \sqrt{(-5 - 2)^2 + (-2 + 2)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(-7)^2 + (0)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(49) + (0) }[/tex]
Add.
[tex]d = \sqrt{(49)[/tex]
Evaluate the radical.
d = ±7
Since distance cannot be negative, our answer is 7.
The distance between the two points is 7 units.
Hope this helps!

Can someone help me plz I need both the area and perimeter thank you
Answer:
Step-by-step explanation:
do this in parts, take the rectangle in the middle and then the two ends as a whole circle. :)
the rectangle: perimeter : 2*10 ft + 2* 6ft= 32ft
the area: 10*6 = 60 [tex]ft^{2}[/tex]
The circle: perimeter: circumference of circle = 2[tex]\pi[/tex]r or diameter[tex]\pi[/tex] (same thing)
6[tex]\pi[/tex] =18.84955592 ft
area: area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
[tex]\pi[/tex][tex]3^{2}[/tex] = 28.27433388 [tex]ft^{2}[/tex]
add the two part for the totals
total perimeter is: 32 +18.84955592 = 50.84955592 ft
total area is: 60 + 28.27433388 = 88.27433388 [tex]ft^{2}[/tex]

One number is 8 more than another, and their sum is 80. What is the smaller number?
34
36
38
40
========================================================
Work Shown:
x = smaller number
x+8 = larger number, since it's 8 more than the smaller value
Add up those two expressions, and set the sum equal to 80.
Then solve for x.
x+(x+8) = 80
2x+8 = 80
2x = 80-8 ... subtract 8 from both sides
2x = 72
x = 72/2 .... divide both sides by 2
x = 36
The smaller value is 36 while the larger value is x+8 = 36+8 = 44
Note how 36+44 = 80 to help verify the answer.
Answer:
34.
Step-by-step explanation:
80 = (34 + 8) + x
80 = 42 + x
38 = x
^^ that is an answer, but the question asks for the SMALLER number... Which is up at the beginning of my equation.
I hope this helps. I'm not entirely sure if it's correct, but it's worth a shot... lol
Which expression is equivalent to 7x^2-(8x-5)+(5x-3x^2)?
Answer:
your mo- (3x^5 + 8x^3) - (7x^2 - 6x^3) = 3x^5 + 8x^3 - 7x^2 + 6x^3 = 3x^5 + 14x^3 - 7x^2

Which sentence is true about equilateral triangle .
A.only 2 sides are the same length
B.only 2 angels have the same measure
C. Each side is a different length
D. All sides are the same length
E. Each angel has a different measure
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Equilateral triangles.
Since, from the name itself, equilateral triangles have all sides and angles equal.
Hence the correct answer is
==> D. All sides are the same length.
What is partial fraction decomposition?
Can you explain it and give an example of it please?
thank you :)
Answer:Partial-fraction decomposition is the process of starting with the simplified answer and taking it back apart, of "decomposing" the final expression into its initial polynomial fractions. To decompose a fraction, you first factor the denominator. ... "Partial-Fraction Decomposition: General Techniques."

Finding a final amount in a word problem on exponential growth or decay
The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 185 grams of a radioactive isotope, how much will be left after 3 half-lives?
Use the calculator provided and round your answer to the nearest gram.
Answer:
25 grams
Step-by-step explanation:
Three half live
1/2 * 1/2 * 1/2 = (1/2)³ = 1/8
There would be 1/8 of the original amount left
185 * 1/8 = 23.125
Rounded
25 grams

Linda walked a total of 26 1/4 miles during a 4 day period. The distances she walked are described below.
• She walked 6 1/3 miles the first day.
• On the second day, she walked 9 1/2 miles
• She walked 5 1/4 miles on the third day.
How far did she walk on the fourth day?
[tex]1st \: day + 2nd \: day + 3rd \: day + 4th \: day = 26\frac{1}{4} \\ 6\frac{1}{3} + 9\frac{1}{2} + 5\frac{1}{4} + x = 26\frac{1}{4} \\ \frac{253}{12} + x = \frac{105}{4} \\ x = \frac{105}{4} - \frac{253}{12} \\ x = \frac{31}{6} = 5\frac{1}{6} [/tex]
