Answer:
9 monthsStep-by-step explanation:
Given the relationship of the dogs weight ang its age modeled by the equation;
w = 6m+4
m represents its age in months, and;
w represents its weight in pounds
Given
w = 58pounds
Required
number of months m before the dog weigh 58pounds;
Substitute w = 58 into the function and get m as shown;
w = 6m + 4
58 = 6m + 4
subtract 4 from both sides
58-4 = 6m+4-4
54 = 6m
divide both sides by 6
54/6 = 6m/6
9 = m
m = 9
Hence it will take 9months before the dog will weigh 58 pounds

Kyra observed that 85% of the students at a library liked reading mystery stories. If 30 students at the library did not like reading mystery stories, the number of students at the library who liked mystery stories was _____. (only put numeric values, no other symbols)
Answer:
The first thing we must do is find the percentage of students who do not like to read mystery stories.
We have then:
Then, to find the number of students who like to read mystery stories, we can make the following rule of three:
15% ----------------> 30 students
85% ----------------> x
From here, we clear the value of x.
We have then:
the number of students at the library who liked mystery stories was 170

the sum in the form a(b+c) such that the integers band chave no common factor.
99 +33
Answer:
33(3+1)
Step-by-step explanation:
Find the GCF of 99 and 33
99=3^2•1133=3•11So the GCF is 3•11=33Factor 33 out
33(3+1)How to use distributive property to find 12 + 20 ?
Answer:
The distributive property states that
a*(b + c) = a*b + a*c
You can use the distributive property in reverse to factor out a common factor from the sum of 2 numbers. If you realize that 12 = 4*3 and 20 = 4*5 then you can write
12 + 20 = 4*3 + 4*5 = 4*(3 + 5)

The cubic polynomial below has a double root at x=-4 and one root at x=6 and passes through the point (2,36) as shown. Algebraically determine it’s equation in factored form.
Answer: P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)
Step-by-step explanation:
The factored form of a polynomial is:
P(x) = A*(x - r₁)*(x - r₂)*(x - r₃)....
Where:
A is a real number.
r₁, r₂,.... etc
are the roots.
In this case, we know that the roots are:
-4, -4, and 6.
Then the polynomial will be:
p(x) = A*(x + 4)*(x + 4)*(x - 6)
Now we also know that this polynomial passes through the point (2, 36)
This means that:
P(2) = 36 = A*(2 + 4)*(2 + 4)*(2 - 6) = A*6*6*(-4) = A*(-144)
36 = A*(-144)
-36/144 = A
-0.25 = -1/4 = A
Then the polynomial is:
P(x) = (-1/4)*(x + 4)*(x + 4)*(x - 6)
Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf, but does not want to put the Steelie and the Tiger next to one another. In how many ways can she do this?
Answer:
Step-by-step explanation:
Oops I meant "there are 3! = 6 ways to permute ABTS that have TS."
There are 12 different combinations to display marvel that doesn't involve Steelie and the tiger.
What are permutation and combination?A permutation is an orderly arrangement of things or numbers. Combinations are a means to choose items or numbers from a collection or set of items without worrying about the items' chronological order.
Given, Zara has a collection of 4 marbles: an Aggie, a Bumblebee, a Steelie, and a Tiger. She wants to display them in a row on a shelf but does not want to put the Steelie and the Tiger next to one another.
We want the number of ways to permute the string ABST that has S and T separated.
Total ways of displaying marbles = 4! = 24
If S and T are together, then the permutation contains the consecutive pair ST or TS somewhere. We can count these possibilities by regarding ST or TS as a single symbol
permutation of getting them together = 2 * 3!
permutation of getting them together = 12
Thus,
total desired combination = Steelie and tiger do not come together
total desired combination = 24 - 12 = 12
therefore, There are 12 possible combinations of displaying marvel without making Steelie and tiger together.

Two parallel lines are crossed by a traversal. What is the value of h?
h=60
h=80
h=100
h=120
Answer:
h=60
Step-by-step explanation:
The angle that is 120 degrees and the angle that is h degrees are called same side interior angles
Same side interior angles are supplementary, meaning that they add to 180 degrees
To find h we can use Measures addition postulate to find the unknown value h
h+120=180
h=60

P(A) = 2/5 P(B) = 1/2 P(A or B) = 9/10
9514 1404 393
Answer:
mutually exclusive
Step-by-step explanation:
The formula of interest is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, we have ...
9/10 = 2/5 + 1/2 - P(A and B)
Solving for P(A and B), we get ...
P(A and B) = 2/5 +1/2 -9/10 = 4/10 +5/10 -9/10
P(A and B) = 0
__
Events are mutually exclusive when they can never happen at the same time. That is, P(A and B) = 0.
The events A and B are mutually exclusive.

Piper is at the grocery store and plans on buying cans of soup and frozen dinners, but
is concerned about their sodium content. Each can of soup has 150 mg of sodium and peach frozen dinner has 450 mg of sodium.
How many milligrams of sodium are there in 4 cans of soup and 2 frozen dinners?
How many milligrams of sodium are there in c cans of soup and f frozen dinners?
Answer:
1,500 mg
150c + 450f
Step-by-step explanation:
Each can of soup has 150 mg of sodium and each peach frozen has 450 mg of sodium.
Piper plans to buy some of each product and wants to know how many milligrams of sodium are there in 4 cans of soup and 2 frozen dinners.
Since each can of soup has 150 mg of sodium, 4 cans have 4*150 = 600 mg of sodium.
Each frozen dinner has 450 mg of sodium, thus 2 of them have 2*450 = 900 mg of sodium.
There are 600 + 900 = 1,500 mg of sodium in this combination.
If Piper buys c cans of soup and f frozen dinners, they will have 150c + 450f milligrams of sodium.

Answer:
The slope is -2!
Step-by-step explanation:
Lets Solve!
3y +6x = 9
First we subtract 6x from both sides
3y = -6x + 9
Next we divide by 3 from both sides.
y = -2x + 3
The slope is -2!
