60/100 * 75 & 0.60 * 75
60% can be rewritten as 0.60, and since 60/100=0.60, this expression is correct as well
The other two are incorrect because 0.60/100 would be 0.6%, and 60*75 would mean she is saving 6000%

2) What is the solution to the system of equations?
A) (6, 10)
B) (9.5)
(10.6)
D) (14.10)
Answer:
D) (14.10)
Step-by-step explanation:
x-y=42x -3y= -2
2. (x-y=4)2
(2x -3y= -2) 1
3. 2x-2y=8 (equation 1)
2x-3y =-2 (equation 2)
4.subtract equation 2 from equation 1 to eliminate x
5. y= 10
6. use either of the initial equations to find x eg.
x-y = 4
x- 10= 4
x = 10 + 4
x= 14
therefore x,y = 14,10

Harrison and Sherrie are making decisions about their bank accounts. Harrison wants to deposit $300 as a principal amount, with an interest of 5% compounded quarterly. Sherrie wants to deposit $300 as the principal amount, with an interest of 3% compounded monthly. Explain which method results in more money after 2 years. Show all work someone please help me i beg
Answer:
Sherrie's method will make more money.
Step-by-step explanation:
They both deposit 300 dollars, since Harrison is compounding at 5% quarterly she will be making $15 every quarter and since there are 4 quarters per yr at the end of the year Harrison will be sitting at $360.
Whereas Sherrie is compounding at 3% per month so she will be making $9 per month and multiply that by 12 she will be sitting at $408 by the end of the year hence Sherrie makes more.

Using proportions, it is found that he should collect 80 signatures in each week.
What is a proportion?A proportion is a fraction of a total amount.
He currently has 520 signatures, and needs 1000, hence he needs to collect more 1000 - 520 = 480 signatures.
He has six weeks to collect the signatures, hence the number he needs to collect each week is given by:
N = 480/6 = 80.

write a function for the line that includes the points (4,-5) and (8,-7)
Answer:
[tex]y = -\frac{1}{2} x - 3[/tex]
Step-by-step explanation:
Answer:
f(x) = -1/2x - 3.
Step-by-step explanation:
The slope of the line = ((-7 - -5) / (8 - 4)
= -2/4
= -1/2.
y - y1 = m(x - x1)
m = -1/2, x1 = 8 and y = -7 so:
y - (-7) = -1/2(x - 8)
y + 7 = -1/2x + 4
y = -1/2x - 3.
Nadia needs one cup of ice cream for every student in her class for their year-end party. the ice cream is only sold in pints. if there are 24 students in her class, how many pints of ice cream will she need? describe how to solve this problem.
Answer:
12 pints
Step-by-step explanation:
There are 24 students & each one gets 1 cup, so you will need 24 cups total. There are 2 cups in a pint. You divided the 24 cups you need by 2 cups in a pint to get the answer of 12 pints.
You can double check: 12 pints converted to cups (2 cups in a pint) is 12 x2 = 24 cups

Step-by-step explanation:
You just add tgem ad yeah
Answer:
Step-by-step explanation:
barrier = parameter, so we add all the sides:
8+3+3+5+5 = 24
24*1.75 = $42.
THEN, we need the area to solve for the mulch.
I would split it up into two parts so the rectangle and then the triangle.
First, 8*3 is 24
now we divide this by four because one bag covers four square feet
so, 6 bags (24/4=6) which is $36 (6*$6).
_______________
Now, the triangle, which a = (hb*b)/2
12 divided by four again so 3
3 * 6 = $18.
Now we add ALL costs up to get
42+36+18 = $96 total for the entire project.

Answer:
x= 1/10
Step-by-step explanation:
First, factor out the common term of 2:
2(4-x)/3 - 2x-3/2 = 4
Multiply both sides by 6(the LCM of 2,3):
4(4-x) - 3(2x-3) = 24
Distribute:
16-4x - 6x + 9 =24
Add like terms:
25-10x=24
Subtract 25 from both sides:
25-10x(-25) = 24-25
-10x=-1
Divide by -10:
-10x/-10 = -1/-10
Solve for x:
x= 1/10

Answer:
see explanation
Step-by-step explanation:
(c)
1 unit right means add 1 to the x- coordinate
2 units down means subtract 2 from the y- coordinate.
A (1, 3 ) → A' (1 + 1, 3 - 2 ) → A' (2, 1 )
B (4, 5 ) → B' (4 + 1, 5 - 2 ) → B' (5, 3 )
C (3, 1 ) → C' (3 + 1, 1 - 2 ) → C' (4, - 1 )

A line passes through the point (-6, 9 and has a slope of 3 Write an equation in point-slope form for this line.
Answer:
y=4/3x+17
Step-by-step explanation:
y-y1 = m(x-x1)
m is the slope
y-9 = 4/3(x-(-6))
y-9 = 4/3(x+6)
y-9 = 4/3x+8
y-9 = 4/3x+8

A tree is struck by lightning and snaps off 34 feet above the ground. The top part of the tree, 117feet long, rests with the tip on the ground whole the broken end rests on the top of the stump. What angle does the top part of the tree make with the ground
Answer:
17 degrees
Step-by-step explanation:
See attached image.
We conclude that the angle at the top measures 65.8°.
What angle does the top part?The whole tree measures 117 ft, and it is broken 34 ft above the ground, forming this way a right triangle.
Then one cathetus of the right triangle measures 34ft, and the hypotenuse measures 117ft - 34ft = 83ft
The angle at the top is θ, the adjacent cathetus to it is the one that measures 34 ft, then to get the angle we can use the relation:
cos(θ) = (adjacent cathetus)/(hypotenuse)
Replacing what we know, we get:
cos(θ) = (34 ft)/(83ft) = 34/83
Solving for θ, we get:
θ = Acos( 34/83) = 65.8°
So we conclude that the angle at the top measures 65.8°.

B.The sum of the measures of the interior angles of a convex polygon is given. What kind polygon is each?
Answer:
Below in bold.
Step-by-step explanation:
The formula for the number of degrees in a convex polygon of side length n is S = 180(n - 2)
Solving for n:
n - 2 = S/180
and n = (S/180) + 2.
1. n = (900/180) + 2 = 5 + 2 = 7 . This is a heptagon.
2. n = (1800/180) + 2 = 12. A duodecagon.
3. n = (2160/180) + 2 = 14 sided polygon.
4. n = (2520/180) + 2 = 16 sided polygon.
5. n = (3420/180) + 2 = 21 sided polygon.

B. False
SUBMIT
Answer: True
Step-by-step explanation:
It passes the vertical line test, no two points are on the same x value
Correct option is A .True . The given graph is of a function by vertical line test
What is a vertical line test for function?The vertical line test is a test that checks whether a given graph is of a function or not. It states that every vertical line passing through the given graph should intersect the graph at most one point .( which comes from the definition of function that that a function takes every point in the input set to a unique image in the codomain set)
For the given graph whenever we will draw a vertical line passing through any point on the domain then it will cut the graph at one point only this can be seen in the attached figure.
Therefore, its true that the given graph represents a function.
∴Correct option is A. True.
