Solve w^2+13w+42=0 by factoring.
Answer: {-7, -6}
Explanation: When an equation has a squared term in it,
it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to 0, then factor.
Since this equation is already set equal to 0, we can factor the left side.
The left side is a trinomial that can be
factored as the product of two binomials.
The first term in each binomial will be a factor of the w².
Since w² factors a w · w, we use a w as our first term.
For the last terms, we use factors of 42 that add
to 13 and these factors are +7 and +6.
So we have (w + 7)(w + 6) = 0.
So either w + 7 = 0 or w + 6 = 0.
Solving for w in each equation, we find that our solution set is {-7, -6}.

Wezi has sixty-three $5-bills. He takes the $5-bills to the bank to exchange them for $20-bills. How many $20-bills does Wezi get? Is there money left over? Explain.
Answer: 15
Step-by-step explanation:
From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:
= 63 × $5
= $315
We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:
= $315 / $20
= 15 3/4
Therefore, he will get 15 $20 bills

A penny is about 5×10−3 feet thick. The One World Trade Center building is about 2,000 feet tall. How many pennies would be in a stack of pennies as tall as the One World Trade Center building?
Answer:
400000 pennies
Step-by-step explanation:
A penny is about 5×10^-3 feet thick. The One World Trade Center building is about 2,000 feet tall.
The number of pennies that would be in a stack of pennies as tall as the One World Trade Center building is calculated as:
Height of the building ÷ Thickness of a penny
Height of the building = 2000 feet
Thickness of a penny = 5 × 10^-3 feet
Hence:
= 2000feet/ 5 × 10^-3 feet
= 400000 pennies

A five-gallon bucket was completely filled with water. The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes. If the leak continues at the same rate, how long will it take for the bucket to become half full? 1 gal = 128 fl oz
Answer:
600 minutes
Step-by-step explanation:
We start with a bucket that is completely full- it has five gallons of water.
5 gallons of water = 5 (128) fl oz = 640 fl oz
Half of 640 fl oz is 320 fl oz, which is the amount we are looking for.
So, we divide [tex]\frac{320}{8}[/tex] to find how many times it will take for the bucket to become half-full, which is 40 times.
Now, we multiply 40 by 15 minutes, so we get 40 × 15 = 600 minutes
Time for the bucket to become half full is 600 minutes.
Here,
A five-gallon bucket was completely filled with water.
The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.
We have to find the time for the bucket to become half full.
What is Number system?
A number system is defined as a system of writing to express numbers.
Now,
A five-gallon bucket was completely filled with water.
The bucket has a small leak that causes it to lose 8 fluid ounces of water every 15 minutes.
Hence, We start with a bucket that is completely full- it has five gallons of water.
So, Amount of 5 gallons of water = 5 * 128 = 640 fl oz
Now, Half of 640 fl oz = 640/2 = 320 fl oz
So, we divide to find how many times it will take for the bucket to become half-full as;
⇒ 320 ÷ 8 = 40
Now, Time is calculated as to multiply 40 by 15 minutes,
⇒ 40 × 15 = 600 minutes
Hence, Time for the bucket to become half full is 600 minutes.

For this triangle, to find x, we will use the cosine trigonometric function.
cosine functions look like this:
[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]
(The weird looking symbol is called theta, and represents an angle measurement)
Plug in the values into the equation.
cos(42) = [tex]\frac{x}{15}[/tex]
Multiply both sides by 15.

Rearrange x= 3g + 2 to make g the subject
Answer:
g = 1/3 x - 2/3
Step-by-step explanation:
x =3g + 2
Switch sides:
3g + 2 = x
Take away 2 from both sides:
3g = x - 2
Divide both sides by 3:
g = 1/3 x - 2/3
Use the function h(x)=3x-5, for what value of x will h(x)=28
Answer:
x = 11
Step-by-step explanation:
3 x 11 = 33
33-5 = 28
x = 11
Answer:
10
Step-by-step explanation:
Given
h(x) = 3x - 5
h(x) = 25
3x - 5 = 25
3x = 25 + 5
3x = 30
x = 30 / 3
x = 10
What is the solution to -2|2.2x - 3.3| = -6.6?
O x=-3
O x=3
O x=-3 or x = 0
O x = 0 or x = 3
The solution to the equation, -2|2.2x - 3.3| = -6.6, which contain an absolute value, is: D. x = 0 or x = 3.
What is the Solution of an Equation with an Absolute Value?To determine the solution, we have to isolate the value and find its value.
Given the equation, -2|2.2x - 3.3| = -6.6:
-2|2.2x - 3.3| = -6.6
2.2x + 3.3 = 3.3
2.2x = 3.3 - 3.3
2.2x = 0
x = 0/2.2
x = 0
Or
2.2x - 3.3 = 3.3
2.2x = 3.3 + 3.3
2.2x = 6.6
x = 6.6/2.2
x = 3
The solution is: D. x = 0 or x = 3
