5/12 cups of dog food are recommended for a 25-pound adult dog by using the proportion.
We are given that:
The relationship between x and y
We need to find the dog food for the 25-pound adult dog
The weight of the adult dog (X) is proportional to the amount of dog food in cups are proportional.
x = k y
k = x / y
k = 10 / 1/6
k = 10 (6)
k = 60
Let the dog food recommended for the 25-pound adult dog be y.
Weight of the dog = x = 25 pounds
Cups of dog food recommended = y
k = 60
Using the equation for the given relationship:
25 = 60 × y
y = 25 / 60
y = 5 / 12
Therefore, 5/12 cups of dog food are recommended for a 25-pound adult dog by using the proportion.

in june 2012, a gallup poll asked u.s. adults whether immigration was a good thing or a bad thing for the country. out of 1004 respondents, 663 said it was a good thing.
The 95% confidence interval for the proportion who believe immigration is a good thing is 0.631< p < 0.689.
What is immigration?Immigration is the term used to describe the international movement of individuals to a country of destination where they do not have nationality or ancestry in order to settle as citizens or permanent residents. The definition of immigration or migration excludes commuters, tourists, and other short-term visitors; seasonal labor immigration is occasionally included, though.
Research indicates that migration has favorable economic impacts for both the sending and receiving countries. The majority of the time, according to research, immigration benefits the native people economically. However, there is some debate over whether low-skilled immigration has a negative impact on low-skilled natives.
Given that,

What is the slope-intercept form of the equation of the line that passes through the point (-6, 1) and is perpendicul
to the graph of 2x + 3y = -5?
y=-x-8
y=-3x+1
y=x+1
y = x + 10
The equation of the line as it passes through the point (-6, 1) is
y = 3x/2 + 10
How to Calculate a Slope ?Slope is the same as gradient which is the ratio of change in y to change in x. That is,
gradient m = Δy / Δx
Given that the equation of the line passes through the point (-6, 1) and is perpendicular to the graph of 2x + 3y = -5
Let us first find the slope, 3y = -2x - 5
y = -2x/3 - 5/3
Slope m = -2/3
Let us use the formula Mm = -1
M = -1/m
M = -1 × -3 /2
M = 3/2
The equation of the line as it passes through the point (-6, 1) will be
M = (Y - Y1) / (X - X1)
3/2 = (y - 1) / (x + 6)
Cross multiply
2(y - 1) = 3(x + 6)
2y - 2 = 3x + 18
Collect the like time
2y = 3x + 18 + 2
2y = 3x + 20
y = 3x/2 + 10
Therefore, the equation of the line as it passes through the point (-6, 1) is y = 3x/2 + 10

Evaluate expression if r=3, q=1 , and w=-2 .
r w-6
The result of evaluating the expression r w-6 is equal to -12.
To evaluate an expression is a term used in maths that generally means to come up with a solution to an equation and if it is not possible then reduce it to a smaller equation by exchanging the variables with the given numerical values.
We can evaluate the given expression as follows:
Since r = 3 and w = -2, we can substitute r and w in the expression, r w-6, with 3 and -2 respectively.
r w - 6 = 3 (-2) - 6
3 (-2) - 6 = -6 -6 = -12.
Hence if we evaluate the expression r w-6, the result will be -12.

Her friend bought the same T - shirt for $ 17.5 after 30 % discount.
We are given that a girl bought a T- shirt for $ 25.
Selling price = $ 25
Now, her friend bought the same T- shirt for 30 % off.
Discount rate = 30 %
Let the discounted price at which her friend bought the t - shirt be x.
So, we get that:
x = $ 25 - 30 % of $ 25
x = $ 25 - 30 / 100 × 25
x = $ 25 - $ 7.5
x = $ 17.5

Given the area, the lengths of the diagonals p and q of the rhombus are 4√7 cm and 12√7 cm respectively.
What are the lengths of the diagonals of the rhombus?A rhombus which is called an equilateral quadrilateral is simply a quadrilateral whose all four sides have the same length.
The area of a rhombus is expressed as;
A = ( p × q )/2
Where p and q are the diagonals
Given the data in the question;
Let one of the diagonal be x.
Area of the rhombus = 168cm²Diagonal p = xDiagonal q = 3xPlug in the given values into the equation above and solve for x.
A = ( p × q )/2
168 = ( x × 3x )/2
168 = ( 3x² )/2
3x² = 168 × 2
3x² = 336
Divide both sides by 3
x² = 112
Take the square root of both sides
x = ±√112
x = ±4√7
Since the dimension of the rhombus cannot be negative,
x = 4√7
Hence, the length of the diagonals are;
Diagonal p = x = 4√7 cm
Diagonal q = 3x = 3( 4√7 ) = 12√7 cm

find the measure of each lettered angle. a=, b=, c=, d=, e=
Answer:
a= 20
b= 70
c= 20
d=70
e=110
Step-by-step explanation:
a + the 70 degree angle have to equal 90 degrees (the right angle marking) and the same with b + a. So to ind a, you do 90-70 and to find b, because you now have the value of a, you do 90-20.
a+b+c+70 is equal to a 180 degree angle, so since you know the value of a and b, now you can figure out c by doing 180-(70+20+70).
d and the 70 degree angle are vertical angles so they are equal to each other.
lastly for e, d+e is equal to 180 degrees so since you know the value of d, you just do 180-70 to find e.
Answer:
a = 20°
b = 70°
c = 20°
d = 70°
e = 110°
Step-by-step explanation:
Angle A is complementary with 70°, so they add together to = 90° (as indicated by the 90° mark).
90° - 70° = 20°
Angle A = 20°
Angle B is complementary with angle A, 20°, so they also add together to = 90°.
90° - 20 = 70°
Angle B = 70°
Although not indicated by a 90° mark, Angle C and Angle B are complementary since they share a straight line with the complementary angles A and 70°. This means Angles C + B = 90°
90° - 70° = 20°
Angle C = 20°
Angle D is vertical to 70°, so Angle D = 70°
Angle E is supplementary to 70°, so they should combine to = 180°
180° - 70° = 110°
Angle E = 110°
