Jim has 3 cats, 5 dogs, and 2 rabbits. Match each type of ratio to the
correct description of Jim's pets. Drag the items on the left to the
correct location on the right
part-to-part ratio
5 dogs to 10 per
whole-to-part ratio
3 cats to 5 dogs
part-to-whole ratio
10 pets to 2 rab
Answer:
The correct locations are;
Part to part ratio is 3 cats to 5 dogs
Whole to part ratio is 10 pets to 2 rabbits
Part to whole ratio is 5 dogs to 10 pets
Step-by-step explanation:
The given information are;
The number of cats Jim has = 3
The number of dogs Jim has = 5
The number of rabbit Jim has = 2
The total number of pets Jim has = 3 + 5 + 2 = 10 pets
Therefore;
The fraction of the pets that are cats = 3/10
The fraction of the pets that are dogs = 5/10
The fraction of the pets that are rabbits= 2/10
Therefore we have;
Part to part ratio = 3/10 cats to 5/10 dogs = 3 cats to 5 dogs
Whole to part ratio → 10 pets to 2 rabbits
Part to whole ratio → 5 dogs to 10 pets.

Use completing the square to solve for x in the equation (x-12)(x+4x)=9.
Answer:
x = 6 + 3 sqrt(21/5) or x = 6 - 3 sqrt(21/5)
Step-by-step explanation:
Solve for x over the real numbers:
(x - 12) (x + 4 x) = 9
(x - 12) (x + 4 x) = 5 x (x - 12):
5 x (x - 12) = 9
Divide both sides by 5:
x (x - 12) = 9/5
Expand out terms of the left hand side:
x^2 - 12 x = 9/5
Add 36 to both sides:
x^2 - 12 x + 36 = 189/5
Write the left hand side as a square:
(x - 6)^2 = 189/5
Take the square root of both sides:
x - 6 = 3 sqrt(21/5) or x - 6 = -3 sqrt(21/5)
Add 6 to both sides:
x = 6 + 3 sqrt(21/5) or x - 6 = -3 sqrt(21/5)
Add 6 to both sides:
Answer: x = 6 + 3 sqrt(21/5) or x = 6 - 3 sqrt(21/5)

if you graph the system of Inequalities given below, which points would lie in the solution set? Select all the correct answers.
x-y2-4
2x-ys 5
2y+ x>1
Answer:
(-1,3)
Step-by-step explanation:
we need to replace the values x and y for every point and see if the point satisfies all the inequations.
Point (-2,3):
x - y ≥ -4
-2 - 3 ≥ -4
-5 ≥ -4
Then, -5 is not greater than -4, so that point is not a solution.
Point (-1,3):
x - y ≥ 4 2x - y ≤ 5 2y + x > 1
-1 - 3 ≥ 4 2(-1) - 3 ≤ 5 2(3) + (-1) > 1
-4 ≥ -4 -5 ≤ 5 5 > 1
Then, (-1,3) is a solution
Point (0,0):
x - y ≥ 4 2x - y ≤ 5 2y + x > 1
0 - 0 ≥ 4 2(0) - 0 ≤ 5 2(0) + (0) > 1
0 ≥ -4 0 ≤ 5 0 > 1
Then, 0 is not greater than 1, so that point is not a solution.
Point (2,-2):
x - y ≥ 4 2x - y ≤ 5
2 - (-2) ≥ 4 2(2) - (-2) ≤ 5
4 ≥ -4 6 ≤ 5
Then, 5 is not greater than 6, so that point is not a solution.

Answer:
mBC = 96°
mB = 55°
mC = 77°
mAB = 154°
Step-by-step explanation:
The angle mB inscribes the arc mAC, so we have:
[tex]mB = mAC / 2[/tex]
[tex]mB = 110 / 2 = 55\°[/tex]
The sum of internal angles of a triangle is 180°, so in the triangle ABC we have:
[tex]mA + mB + mC = 180[/tex]
[tex]48 + 55 + mC = 180[/tex]
[tex]mC = 180 - 48 - 55[/tex]
[tex]mC = 77\°[/tex]
Using again the property of inscribed angles, we have:
[tex]mAB = 2*mC = 154\°[/tex]
[tex]mBC = 2*mA = 96\°[/tex]
The figure below is formed by 8 identical rectangles and 1 triangle. Find the
area of the shaded triangle
Answer:
Step-by-step explanation:
Base of triangle = length of the rectangle
Since, all are identical rectangles,
Length of a rectangle= 36/2 = 18 cm
Base of triangle = 18 cm
Height of triangle = length of the rectangle + width of the rectangle
Width of 6 rectangles = 36
Width of 1 rectangle = 36/ 6 = 6 cm
Height of the triangle = 18 + 6 = 24 cm
Area of the shaded triangle = [tex]\frac{1}{2}base*height[/tex]
= [tex]\frac{1}{2}*18*24[/tex]
= 9 * 24
= 216 cm²
What are the coordinates of the point that partitions AB according to the part-to-part ratio 4:3?
Answer:
(-1,0)
Step-by-step explanation:
Here, our interest lies in finding the coordinates that splits the points (-5,-8) and (2,6) in the ratio 4:3. Let the point that does the splitting be called point P
The section formula is used here and the point we are having would be;
P = (mx2 + nx1)/(m+n) , (my2 + ny1)/(m + n)
From the question;
m = 4 and n = 3
x1 = -5, y1 = -8
x2 = 2 , y2 = 6
Plugging these values in the equation above, we have;
P = [4(2) + 3(-15)](3+4), [4(6) + 3(-8)]/(3+4)
P = (8-15)/7, (24-24)/7
= -7/7, 0/7
= (-1, 0)
The coordinates of point P is (-1,0)

he salad contains fruits and vegetables. There are at most 8 pounds of fruits and vegetables in the salad. Write the system of inequalities to represent this situation.
Answer:
The system of inequalities to represent this situation is [tex]x+y \leq 8[/tex]
Step-by-step explanation:
Let the amount of fruits be x pounds
Let the amount of vegetables be y pounds
We are given that There are at most 8 pounds of fruits and vegetables in the salad.
This means that there are less than or equal to 8 pounds of fruits and vegetables in the salad.
So,[tex]x+y \leq 8[/tex]
Hence the system of inequalities to represent this situation is [tex]x+y \leq 8[/tex]
x=4y+7 2x-6y=12 System of equations using substitution
Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
The required solution of the given system of equations are x = 3 and y = -1.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
The given system of equations is below as:
x = 4y + 7 ....(i)
2x - 6y = 12 ....(ii)
To solve the equations, use the substitution method.
Substitute the value of equation x = 4y+7 in (ii), and solve for y
2(4y + 7) - 6y = 12
8y + 14 - 6y = 12
8y - 6y = 2y
2y + 14 = 12
Subtract 14 from both sides of the equation
2y = -2
y = -1
Substitute the value of y = -1 in (i), and solve for x
x = 4(-1) + 7
x = -4 + 7
x = 3
Thus, the required solution of the given system of equations are x = 3 and y = -1.

Resource Allocation You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla go 2 eggs and 3 cups of cream. Into each quart of Continental Mocha go 1 egg and 3 cups of cream. You have in stock 500 eggs and 900 cups ofcream. How many quarts of each flavor should you make in order to use up all the eggs and cream?
Answer:
in order to use up all the eggs and cream, the number of quarts of each flavor that should be made is;
Creamy vanilla x = 200 quarts
Continental mocha y = 100 quarts
Step-by-step explanation:
Let x and y represent the number of quarts of Creamy Vanilla and Continental Mocha that should be made in order to use up all the eggs and cream respectively.
For Creamy Vanilla go 2 eggs and 3 cups of cream
For Continental Mocha go 1 egg and 3 cups of cream.
Total number of eggs = 500 eggs
Total number of cream cups = 900 cups.
For the eggs;
2 eggs × x + 1 egg × y = 500
2x + y = 500 .......1
For the cream cups;
3 cups × x + 3 cups × y = 900
3x + 3y = 900
Dividing through by 3
x + y = 300 .......2
Solving the simultaneous equation;
Subtracting equation 2 from 1
(2x + y) - (x+y) = 500-300
2x -x = 200
x = 200
Substituting x = 200 into equation 2;
200 + y = 300
y = 300 - 200
y = 100
Therefore, in order to use up all the eggs and cream, the number of quarts of each flavor that should be made is;
Creamy vanilla x = 200 quarts
Continental mocha y = 100 quarts

Answer:
z =15cm and
y=9.0cm
Step-by-step explanation:
Use sine rule
12/ sin53 = z / sin 90
Z = 12 x sin 90 / sin 53
Z = 15cm
To find y the angle opposite to y will be 180-(90+53)=37º
So
15/sin 90= y/sin37
y= 15 x sin37 /sin 90
y = 9.0cm

In still water, a boat averages 18 miles per hour (mph). It takes the same amount of time to travel 33 miles downstream (with the current) as it takes to travel 21 miles upstream (against the current). What is the rate of the water's current
Answer:
The rate of the water current is 4mph
Step-by-step explanation:
Let c= the rate of the current in mph
18+c= the rate of the boat going downstream in mph
18-c= the rate of the boat going upstream in mph
t = time in hrs for both upstream and downstream trips
Going downstream:
33=(18+c)*t (1)
Going upstream
21=(18-c)*t (2)
From (1)
33=(18+c)*t
t=33/1(8+c)
Substitute t=33/(18+c) into (2)
21=(18-c)*t
21=(18-c)*33/(18+c)
Cross product
21(18+c)=33(18-c)
378+21c=594-33c
21c+33c=594-378
54c=216
Divide both sides by 54
54c/54=216/54
c=4
Therefore,
The rate of the water current is 4mph
