A rectangular prism has a length of 16in, a height of 15in, and a width of bin. What is
its volume, in cubic in?
Answer:
volume = 240b in³
Step-by-step explanation:
Width is b in
Volume = length * height * width
then:
volume = 16in * 15in * bin
volume = 240b in³

If (3a + 3b + 1) (3a + 3b - 1) = 80, then what is a + b?
Answer: a + b = 3 - maybe
Step-by-step explanation:
( 3a + 3b + 1 )( 3a + 3b - 1 ) = 80
Expand
9a² + 9ab - 3a + 9ab + 9b² - 3b + 3a + 3b - 1 = 80
Simplify
9a² + 9b² + 18ab - 1 = 80
move the 1 over
9a² + 9b² + 18ab = 81
divide by 9
a² + b² + 2ab = 9
not really sure after this part
move the 2ab over
a² + b² = 9 - 2ab
square root both sides
a + b =
simplify
a + b = 3 -
Find angle x and y. Please show step by step process.
Answer:
x = 60, y = 25
Step-by-step explanation:
Δ ABC has 3 congruent sides and is equiangular, thus
the 3 angles are congruent, all 60°
x = 60
∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then
∠ CBD = 180° - 60° = 120°, so
y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle
y = 25

Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation
Answer:
To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.
Step-by-step explanation:
Consider the provided information.
Roots of the equation is x-intercepts or zeros of the given equation.
So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.
Thus, we can find the roots of a quadratic function, by putting f (x) = 0.
Now, let (x-a)(x-b) is the factor of any quadratic equation.
To find the roots of the quadratic function we will put our factor equal to 0.
[tex](x-a)(x-b)=0[/tex]
Now by the zero product property either x-a=0 or x-b=0
[tex]x-a=0[/tex] then [tex]x=a[/tex]
or
[tex]x-b=0[/tex] then [tex]x=b[/tex]
So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Trisha has $100 to spend on presents for 4 friends. She wants to spend the same amount on each friend. Write and solve an inequality to determine how much can she spend on each friend?
Answer:
4x<=100
Step-by-step explanation:
she has 4 friends to spend the 100 dollars on because she wants to spend the same amount on each friend you can multiply 4x. you can't spend more than 100 but you can spend 100$ so it would be <=100
Solve the system of linear equations by elimination.
9x+y=2
−4x−y=−17
Answer: x = -3 y = 29
Step-by-step explanation:
9x + y = 2
-4x - y = -17
5x = -15
Divide both sides by 5
x = -3
9x + y = 2
Substitute -3 for x
9 (-3) + y = 2
-27 + y = 2
Add 27 to both sides
y = 29

Answer:
Second Choice.
Step-by-step explanation:
The shifting of graph depends on value of b.
[tex]y = mx + b[/tex]
If b > 0, the graph shifts up.
If b = 0, the graph passes origin point.
If b < 0, the graph shifts down.
The only thing that's matter if the graph shifts up or down is about if the value of b is in negative or positive.
Henry has q5 lawns mowed out of total 60 lawns what percent of the laws does. Henry still have to mow
Answer:
Henry still has to mow 75% of the laws.
Step-by-step explanation:
It is given that Henry has 15 lawns mowed out of a total of 60 lawns.
We need to find: What percent of the lawns do Henry still have to mow?
Henry has 60 lawns in total.
He mowed 15 out of them.
The percentage of lawns mow = [tex]\frac{15}{60} \times 100=25 \%[/tex]
Henry mowed 25% of total lawns.
The percent of laws still have to mow = 100%-25%
The percent of laws still have to mow = 75%
Hence, Henry still has to mow 75% of the laws.
