1) Note that Mike bought 12 1/2 lbs and the dogs ate 3/5 of those 12 1/2 lbs. So let's first rewrite that mixed number into an improper fraction for convenience:
\(12\frac{1}{2}=\frac{2\times12+1}{2}=\frac{25}{2}\)Note that we kept the denominator.
2) So now, let's calculate how much food did the dogs eat by multiplying
3/5 by this 25/2
\(\frac{3}{5}\times\frac{25}{2}=\frac{75}{10}=\frac{15}{2}=7.5lbs\)Note that we simplified that fraction to get an irreducible number

Use the drop-down menus to explain your answer. The has the greater volume because the fits within the with extra space between the two figures.
The rectangular prism has a greater volume than the cylinder.
Volume of shapesThe rectangular prism has a greater volume than the cylinder. This is because the rectangular prism fully occupies the space within its boundaries, while the cylinder has empty space above and below it.
The cylinder's rounded shape leaves gaps between its curved surface and the boundaries of the rectangular prism.
Therefore, the rectangular prism can hold more volume than the cylinder as it utilizes the entire space within its shape efficiently.

a student spends 18 out of 35 of his pocket money on transport and fruit what is the fraction left?
To find the fraction of pocket money left after spending on transport and fruit, we need to subtract the amount spent from the total pocket money and express it as a fraction.
The student spends 18 out of 35 of his pocket money, which means he has (35 - 18) = 17 units of his pocket money left.
Therefore, the fraction of pocket money left can be written as 17/35.

If one wanted to solve the equation below using the quadratic formula, what would be the b value used to substitute into the quadratic equation.
3x 2 − 2 = - 5x
Answer:
b = 5
Step-by-step explanation:
All quadratic equations are formed in the format of \(a^{2}\) + bx + c = 0
Using this formula, we can re-arrange the equation to fit the given format.
\(3x^{2}\) - 2 = -5x
\(3x^{2}\) + 5x - 2 = 0
5 is plugged in for "b" in this equation, therefore b = 5.

There was a carton of 27 bottles of water at the beginning of a sports meet. The carton, with 27 bottles of water in it, weighed 11.53 kg. After the sports meet had ended, there were 24 bottles of water left in the carton. The carton then weighed 10.33 kg. What would be the mass of the carton in grams if it were to be empty?
Answer:
is the ans 0.73
Step-by-step explanation:
is the ans 0.73 gram and time xa ra
The mass of the carton in grams if it were to be empty is 530 g
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let us find the weight of one bottle of water.
We have to subtract the weight of the carton with 27 bottles from the weight of the carton with 24 bottles
11.53 kg - 10.33 kg = 1.20 kg
So, the weight of 3 bottles of water is 1.20 kg.
Divide 1.2 by 3 to find the weight of one bottle of water
1.20 kg / 3 = 0.4 kg
Now the weight of the empty carton
Subtract the weight of 27 bottles from the weight of the carton with 27 bottles:
11.53 kg - 27(0.4 kg) = 0.53 kg
Convert the weight of the empty carton from kilograms to grams:
0.53 kg × 1000 g/kg = 530 g
Therefore, the mass of the carton in grams if it were to be empty is 530 g

Referring to the figure, the two rectangles shown have
equal areas. Find the value of x.
Answer:
x = 2
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × breadth
given the rectangles have equal areas then equating the two areas gives
4x × 9 = 4(6x + 6) , that is
36x = 24x + 24 ( subtract 24x from both sides )
12x = 24 ( divide both sides by 12 )

Solve the equation 2x-4y=4 for y
Answer:4-2x/4
Step-by-step explanation:
The equivalent value of the expression is y = ( 1/2 )x - 1
Given data ,
Let the equation be represented as A
Now , the value of A is
2x - 4y = 4
On simplifying the equation , we get
2x - 4y = 4
So , the left hand side of the equation is equated to the right hand side by the value of ( 4 )
Adding 4y on both sides , we get
2x = 4y + 4
Subtracting 4 on both sides , we get
4y = 2x - 4
Divide by 4 on both sides , we get
y = ( 2x - 4 ) / 4
On simplifying , we get
y = ( 1/2 )x - 1
Therefore , the value of y = ( 1/2 )x - 1
Hence , the expression is y = ( 1/2 )x - 1

Let U be the universal set consisting of all the letters in the English alphabet. Let A be the subset of U consisting of all the consonants. Find Ac. Write your answer in proper set notation, for example {a,b,c,d,e}.
Do not write Ac= in your answer.
Answer:
{a, e, i, o, u}
Step-by-step explanation:
Since U is the universal set of all the letters in the English alphabet = {a, b, c, ......, x, y, z}
and A is the subset containing all the consonants,
Ac which is the complement of set A must be all the letters that are not consonants.
This would be the set of all vowels
a, e, i , o, u
No distinction made between upper and lowercase letters
Given that U is the Universal set and we are to find the subset that is not the consonants then the values that we would have would be the vowels {a, e, i, o, u}
What is set in mathematics?This is the term that is used to refer to the collection of different elements in the field of mathematics and statistics.
The Universal set here would be all of the alphabets
This would be
U= {a, b, c ,d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z}
The consonant is a subset of the universal set U.
This would be
A= {b, c ,d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z}
The we have another subset that is defined as Ac, these are the values that are not contained in the set A.
Hence the value would be {A, e, i, o, u} That is the vowels in the alphabet.

The number of different choices of eleven questions that a student can make on an exam with sixteen questions is 4,096.
This number can be calculated by the combination formula. The combination formula is used to calculate the number of combinations of a certain size that can be made from a larger set. In this case, the larger set is sixteen questions and the smaller set is eleven questions. The combination formula, written as C (n,r) is equal to n! / (r! (n-r)!), where n is the size of the larger set and r is the size of the smaller set. Applying this formula to the problem at hand, 16! / (11! (16-11)!), yields 4,096.

A bag contains 10 green,8 blue, and 2 white balls. Naomi seclets 2 balls from the bag at random, one at a time, without replacing them. What is the probability that she selects all two white balls?
E.) 2/95
F.) 1/95
G.) 1/190
H.) 1/380
To find the probability that Naomi selects both white balls, we need to consider the total number of possible outcomes and the number of favorable outcomes.
Total number of outcomes:
Naomi selects 2 balls without replacement, so the total number of outcomes is the number of ways she can choose 2 balls out of the total number of balls in the bag. This can be calculated using combinations:
Total outcomes = C(20, 2) = (20!)/(2!(20-2)!) = (20 * 19)/(2 * 1) = 190
Number of favorable outcomes:
Naomi needs to select 2 white balls. There are 2 white balls in the bag, so the number of favorable outcomes is the number of ways she can choose 2 white balls out of the 2 white balls in the bag:
Favorable outcomes = C(2, 2) = 1
Probability = Favorable outcomes / Total outcomes = 1/190
Therefore, the correct answer is (G) 1/190.

In digging a hole, the construction crew records the depth of the hole relative to the ground level. The starting depth is zero feet. The table shows the proportional relationship between the depth of the hole and the number of hours digging. Find the constant of proportionality. How many hours of digging does it take for the depth of the hole to reach −35.75 feet?
We want to know how hepth is the hole after one work hour.
From the two first lines we can see that they dig a hole from -8.25 to -13.75, then
Δdepth = depth₂ - depth₁ = -13.75 +8.25= -5.5 feet in two hours
Then if we dive we will have the depth each hour
-5.5/2 = -2.75 depth each hour
Constant of proportionality: -2.75
We want to know how many hours correspond to reach -35.75 feet. In order to do so, we divide it by the depth they reach each hour:
-35.75/-2.75 = 13 hours
Answer: it takes 13 hours of diggingPicture included!
Find the unknowns in the graph below:
All the values of x, y and z are,
z = 12.99
y = 7.01
x = 28.3 degree
We have to given that;
In a triangle,
Two angles are, 61.7 degree and 90 degree
And, One side is, 14.76.
Now, We can formulate;
sin 61.7° = Perpendicular / Hypotenuse
sin 61.7° = z / 14.76
0.88 = z / 14.76
z = 0.88 x 14.76
z = 12.99
And, By Pythagoras theorem we get;
14.76² = z² + y²
14.76² = 12.99² + y²
217.85 = 168.74 + y²
y² = 217.85 - 168.74
y² = 49.1
y = 7.01
And, By sum of all the angles in triangle, we get;
x + 61.7 + 90 = 180
x + 151.7 = 180
x = 180 - 151.7
x = 28.3 degree
