Answer:
Solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] and find value of k
Solving:
[tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex]
Convert mixed fraction into improper fraction
[tex]\frac{2}{5}K-\frac{7}{2}K =15[/tex]
Taking LCM of 5 and 2 we get 10
[tex]\frac{2*2K-7*5K}{10} =15\\\frac{4K-35K}{10} =15\\\frac{-31K}{10} =15[/tex]
Divide both sides by -31/10
[tex]\frac{-31K}{10}*\frac{-10}{31}=15* \frac{-10}{31}\\K=\frac{-150}{31} \\K=-4\frac{26}{31}[/tex]
So, solving the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] we get [tex]\mathbf{K=\frac{-150}{31} \ or \ \ K=-4\frac{26}{31} }[/tex]
Jonathan is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months. Write an equation for C,C, in terms of t,t, representing the total cost of the gym membership over tt months.
Answer:
C(t) = 25+34.37t
Step-by-step explanation:
It is given that,
The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months.
We need to write an equation for C in terms of t representing the total cost of the gym membership over t months.
At t=0, Jonathan pays $25 as joining fee.
Equation will be :
C(t) = Co+kt
Initially, Co = 25
C(t) = 25
At t = 8,
C(8) = 25 + k(8) = 300
8k = 275
k = 34.37
⇒ C(t) = 25+34.37t
Hence, this is the required equation.

Find the value of x and y in the parallelogram. Helpp
Answer:
The answer is D.
Step-by-step explanation:
In a parallelogram, lengths are parallel to each other so we can assume that AB is parallel to CD and AD is parallel to BC. In order to find the value of x and y, you have to compare the expressions :
AB // CD
x - 2 = 24
x = 26
AD // BC
y = 11
There is a word problem and idk how to do it here's the word problem [Kari is making copies at a local store of the program for her school play she makes 52 copies and the total is $6.24. How much did the store charge her per copy] this is in math
Answer:
Unitary cost per copy= $0.12
Step-by-step explanation:
Giving the following information:
Total number of copies= 52 copies
Total cost= $6.24
We need to calculate the unitary cost of each copy. To do that, we will use the following formula:
Unitary cost per copy= total cost / number of copies
Unitary cost per copy= 6.24/52
Unitary cost per copy= $0.12
One species of fish in a fishery had an initial population
of 255 fish and after 9 seasons, the population had grown to
480 fish. A second species that was being overfished started
with an initial population of 450 fish, and after the same 9
seasons, it had a new population of 90 fish. Assuming a
linear growth, write the equations for the population of
•each species. Graph your equations in the coordinate plane.
Find the point in the graph which represents when the two
populations will have the same number of fish. After how
many seasons will the second population be eliminated?

Answer:
y = 25x +255y = -40x +450(3, 330)11 1/4 seasonsStep-by-step explanation:
The 2-point form of the equation of a line is useful for these problems. It is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
__
a) The two points are (0, 255) and (9, 480). The equation is ...
y = (480 -255)/(9 -0)(x -0) +255
y = 25x +255
__
b) The two points are (0, 450), (9, 90). The equation is ...
y = (90 -450)/(9 -0)(x -0) +450
y = -40x +450
__
c) The point where both populations are the same is (3, 330).
__
d) The second population will be eliminated after 11 1/4 seasons.

Eugene ate 20% of the Christmas cookies his
grandmother made. If he ate 8 cookies, how
many are left?
Answer:
There are 32 cookies left
Step-by-step explanation:
There are c cookies when we started
c* 20% = 8 cookies
Change to decimal form
c * .20 = 8
Divide each side by .2
c * .2 / .2 = 8/.2
c =40
There are 40 cookies when we started
40 -8 = 32
There are 32 cookies left

Rhombus JKLM with vertices J(-4,7), K(0,8), L(-1, 4), and M(-5,3): (x, y) ------> (x + 2, y - 2)
Answer:
J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, dilation and translation.
Translation is the movement of a point either up, down, left or right on the coordinate plane. If a point A(x,y) is translated a units right and b units up, the new point is at A'(x + a, y + b) while a point A(x,y) is translated a units left and b units down, the new point is at A'(x - a, y - b).
Rhombus JKLM has vertices at J(-4,7), K(0,8), L(-1, 4), and M(-5,3). If a transformation of (x, y) ------> (x + 2, y - 2) is done, i.e. 2 units right and 2 units down, the new points would be at:
J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)

The volume of a single layer in a rectangular prism is 9 cubic centimeters. There are 6 layers in the rectangular prism. What is the total volume, in cubic centimeters, of the rectangular prism?
Answer:
Total volume of the rectangular prism = 54 cubic centimeters
Step-by-step explanation:
Volume of a single layer in a rectangular prism = 9 cubic centimeters
There are 6 layers in the rectangular prism
What is the total volume, in cubic centimeters, of the rectangular prism?
Total volume of the rectangular prism = Volume of a single layer in the rectangular prism × number of layers in the prism
= 9 cubic centimeters × 6 layers
= 54 cubic centimeters
Total volume of the rectangular prism = 54 cubic centimeters

Jason rowed 1/3 of a mile down the river.Jane rowed 2/6 of a mile down the river. Jude rowed 2/9 of a mile down the river.What is the total distance that jason Jane jude rowed down the river in total?
Answer:
8 / 9 miles
Step-by-step explanation:
Given that:
Jason's distance = 1/3 mile
Jane's distance = 2/6 miles
Jude's distance = 2/9 miles
The total miles rowed down the river by all 3 :
(1/3 + 2/6 + 2/9) miles
The L. C. M of the denominator (3, 6, 9) = 18
(6 + 6 + 4) / 18
16 / 18 miles
8 / 9 miles

Heather works at the library. Her weekly income is directly proportional
to the number of hours she works. Last week she worked 16 hours and
earned $116. How much would she earn if she could work 20 hours?
Answer:
$145
Step-by-step explanation:
When you do this type of problem, you want to find the unit rate. In order to do that you divide $116 by 16, and you get $7.25 (how much she make in one hour). Then you multiply $7.25 by 20, and get $145.

A: Miami gets 0.78 more inches of rain.
B:Tampa gets 5.13 more inches of rain.
C: Miami gets 6.12 more inches of rain.
D: Miami gets 5.35 more inches of rain
Miami gets 6.12 more inches of rain.
What is mean by Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
We have to given that;
The average rainfall in inches in Miami from January to May is 1.61, 2.24, 2.99, 3.15, 5.35, and 9.68
While it is 2.24, 2.8, 3.03, 2.05, 2.09, and 6.69 during the same period in Tampa.
Hence, For Miami;
= 1.61 + 2.24 + 2.99 + 3.15 + 5.35 +9.68
= 25.02
For Tampa;
= 2.24 + 2.8 + 3.03 + 2.05 + 2.09 + 6.69
= 18.90
Thus, Find difference as;
= 25.02 - 18.90
= 6.12
Therefore, Miami gets 6.12 more inches of rain.

If is an isosceles triangle, with base AC, AB = 3x+2, BC = 7x-6, and AC = 10x – 10, find the value of x and the length of each side of the triangle.
Answer:
Step-by-step explanation:
If is an isosceles triangle, with base AC, AB = 3x+2, BC = 7x-6, and AC = 10x – 10, find the value of x and the length of each side of the triangle.
The sum of angles in a triangle = 180°
AB + BC + AC = 180°
3x + 2 + 7x - 6 + 10x - 10 = 180°
20x -14 = 180°
20x = 180° + 14
20x = 194
