Answer: x=0, y=56
Step-by-step explanation:
If both triangles are proportional, plug in the equations.
As you can see, you have two equations to work with.
10x+y=56
3x+6=9
get rid of x as a variable first by multiplication.
30x+3y=168
30x+60=90
3y=168
168/3=56
y=56
Now solve for x.
10x+(56)=56
10x=0
x=0

Part B
Please find attached the graph of the inequality created with Microsoft Excel
Part C
1) 4 pounds of apples + 8 pounds of bananas
2) 8 pounds of apples + 6 pounds of bananas
Step-by-step explanation:
Part A
The amount Tony has to buy apples and bananas = $14
The cost of apples per pound = $2
The cost of bananas per pound = $1
Let 'a' and 'b' represent the number of apples and bananas Tony buys respectively, we have;
2·a + b ≤ 14
Part B
In order to plot the inequality, we make one of the variables the subject of the inequality as follows;
b ≤ 14 - 2·a
The above inequality can be plotted with Microsoft Excel and the feasible region shaded as shown in the attached diagram
Part C
Two possible combinations of pounds of apples and bananas that Tony can buy are;
1) 4 pounds of apples and 8 pounds of bananas which gives 2 apples and 8 bananas
2) 8 pounds of apples and 6 pounds of bananas which gives 4 apples and 6 bananas

-3/4x + 1/4
Step-by-step explanation:
Given equation of line: y = mx+c,
where m = slope and c = y-intercept
given m = -3/4,x = -5, y=4,
[tex]4 = ( - \frac{3}{4} )( - 5) + c \\ c + 3.75 = 4 \\ c = 0.25 \: or \frac{1}{4} [/tex]
therefore equation of line :

Once upon a time I weighed 120 pounds. Now I weigh 225 pounds. What is the percent change?
Answers
Answer:
The percent change is 87.5%. (You're one chonky boi lol)
Step-by-step explanation:
To find the percent change, calculate the difference between the new weight and the old weight and divide that value by the old weight and multiply by 100% to find the percent change. In this case, the equation would be [tex]\frac{225-120}{120}[/tex] * 100% = [tex]\frac{105}{120}[/tex] * 100% = 0.875 * 100% = 87.5%, so the correct answer is a percent change of 87.5%.
Answer:
[tex]53\frac{1}{3}[/tex] %
Step-by-step explanation:
[tex]\frac{120}{225} =\frac{y}{100}[/tex]
225 × y = 120 × 100
225y = 12000
225y ÷ 225 = 12000 ÷ 225
[tex]y=53\frac{1}{3}[/tex]

Answers
Answer:
-4, no real solutions
Step-by-step explanation:
b^2 is 16 since b is -4
4ac = 4*1*5 = 20
16 - 20 is -4
no real solutions since you cant get the squareroot out of a negative number (at least not real numbers)
Answer:B
Step-by-step explanation: The discriminant is −4, so the equation has no real solutions.

What is the total volume of metal that makes up the cylinder? Leave your answer in terms of \large \pi and round to the nearest hundredth if necesarry. V = \large \pi mm3
Answers
Answer:
Answer is in picture and explanation below.
Step-by-step explanation:
Continuing from the picture,
Area of Metal base = Area of Bigger Circle - Area of Hollow Circle
=
[tex]1156\pi {mm}^{2} - 225\pi {mm}^{2} \\ = 931\pi {mm}^{2} [/tex]
Volume of Cylinder = Area of Metal base x Height (Length in this case)
=

Find the slope of the line through (4,−5) and (−2,1).
Answers
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (- 2, 1)
m = [tex]\frac{1+5}{-2-4}[/tex] = [tex]\frac{6}{-6}[/tex] = - 1
Answer:
-1
Step-by-step explanation:
To find the slope, plug the values of x and y into the slope formula.
y2 - y1 / x2 - x1
1 - (-5) / - 2 - 4
6 / -6
= -1

Answer: 16+4+4
Step-by-step explanation: The answer is 16, 4, and 4.
Square values in 24 are 4,9, and 16.
You can take a look at this and see that a factor of 24 is 4.
You can do 16+4+4.

In the given rectangle
US = 4x - 16 and RO = x + 2, find RT.
Show all the work
Answers
Answer:
RT = 24
Step-by-step explanation:
Diagonals of rectangles bisects each other and equal in length (congruent) to each other.
Thus
US = RT
US = 2(RO)
4x - 16 = 2(x + 2)
4x - 16 = 2x + 4
2x = 20
x = 10
RT = 2(RO)
= 2(x+2)
= 2(10 + 2)
= 2(12)
= 24
