All you have to do is divide and you do that for all of them. Also did you know quotient means the answer to a division question. Wow! Also, if you see that all I did was add another zero in the middle of the decimals is because That is Decimal Place value. Here is a picture of that just in case. The last answer for the very bottom one is what I just said about decimal place value so here is the reflection: When dividing by tens using decimals always be sure to use place value.

Find the product of (x 5)(x − 5). X2 − 10x 25 x2 10x 25 x2 − 25 x2 25.
Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex](x+5)(x-5) = x^2 - 25[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is obtained as:
[tex](x+5)(x-5) = x(x - 5) + 5(x - 5) \\\\(x+5)(x-5) = x^{1+1} - 5x + 5x - 25 = x^2 - 25[/tex]
Thus,
The product of [tex](x+5)(x-5) = x^2 - 25[/tex]

The sides of One World Trade Center in New York City form
eight isosceles triangles, four of which are 200 ft long at their base BC. The
length AC of each sloping side is approximately 1185 ft.
The value of ∠BAC in the isosceles triangle is 9.7°
Cosine rule
Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:
a² = b² + c² - 2bc*cos(A)
where a, b, c are the sides of the triangle and A, B, C are the angles opposite the sides.
AB = AC = 1185 (isosceles), BC = 200, let ∠BAC = x°, hence:
200² = 1185² + 1185² - 2(1185)(1185)cos(x)
2(1185)(1185)cos(x) = 2808450
cos(x) = 0.9857
x = 9.7°

The denominator is positive for any value of x.
So we solve the numerator:
5ˣ - 1 > 05ˣ > 15ˣ > 5⁰x > 0Suppose the measure of <4 was 105º. Which
answer choice below represents is the measure of
<1?
A. 180°
B. 105°
C. 75°
D. 15°
Answer:
C
Step-by-step explanation:
Angle 1 and angle 4 sit on the same straight line which means
<1 + <4 = 180
We are given that <4 = 105 degrees. So the equation above becomes.
<1 + 105 = 180 Subtract 105 from both sides
<1 = 180 - 105
<1 = 75

Answer:
x = 30
y = 114
Step-by-step explanation:
considering DC || AB the sum of angle <D and angle <A must be equal to 180 because they are supplementary:
5x + x = 180 add like terms
6x = 180 divide both sides by 6
x = 30
Same goes for angle <C and angle <B:
y + 2.2x = 180 we know the value of x is 30
y + 2.2*30 = 180
y + 66 = 180 subtract 66 from both sides
y = 114

Mr. McKinney is planning to purchase new carpet for his large family room. The dimensions of the room are shown in the diagram. How much carpet will he need?
Answer:
204 ft²
Step-by-step explanation:
Let's split the room to make it look like there are two squares.
We can make it to where one square is 14 ft long and 10 ft wide.
The other square can be 16 ft long and 4 ft wide
Find the areas of those two squares by multiplying width and length
14 x 10 = 140
16 x 4 = 64
Add those two together

7. Arrival of the Normandy Train
Claude is waiting to meet the train from Normandy at Gare Saint-Lazare in Paris. He
tells Marie the hour of the train's arrival and he tells Jean at which minute it arrives. He
also tells them both that the train arrives between 0600 and 1000.
They consult the timetable and find the following services between those times:
0620, 0639, 0650; 0717, 0746; 0825, 0839; 0917, 0925, 0950.
Marie then says, “I don't know when Claude's train arrives, but I'm sure that neither does
Jean."
Jean replies, “I didn't know his train, but now I do."
Marie responds, “Now I do as well!"
When is Claude's train and how do you know?
Answer:
0839
Step-by-step explanation:
First of all, let's cancel 0620 and 0746, because they dont have any other number that has the same last 2 digits as them. Jean would've immediately known the train number if it was one of these two.
Now, when Marie says "I'm sure that neither does Jean", it means she is guaranteed Jean doesn't know the train number. It mean she couldnt've gotten 06 or 07, as 0620 and 0746 have it.
We're left with 0825,0839,0917,0925 and 0950
When Jean replies he knows the train number, it means he couldnt've gotten 25, as it's repeated.
And when Marie responds she knows as well, she couldnt've gotten 09, as it's also repeated.
We can cancel 0825,0917,0925 and 0950
So, the train number is 0839
The MRA volleyball team decides to raise some extra money for their trip by horganizing a cookie sale. The cost to make the cookies is $45 and the team is charging $0.25 a cookie. How many cookies must be sold to make a profit of at least $100? write an inequality.
Answer:
Inequality:[tex]0.25x\geq 145[/tex]
Answer: At least 580 cookies
Step-by-step explanation:
Lets say they sell x cookies.
Now, that means they will make 0.25x as their income(the price multiplied by the number of cookies).
We know that totally they need to make 100+45 dollars, because that is what will give them a $100 profit. So they need to make $145
Now just set 0.25x equal to $145.
[tex]0.25x=145[/tex], and now solve
[tex]x=145*4[/tex]
[tex]x=580[/tex]
For an inequality, we could just say that:
[tex]0.25x\geq 145[/tex]
-5 (2b+7) + b < -b -11
Answer:
b > -3
Step-by-step explanation:
-5(2b+7) + b< -b - 11
Distribute -5
-10b - 35 + b < - b - 11
Combine like terms.
-9b - 35 < - b - 11
Add b to both sides.
-8b - 35 < -11
Add 35 to both sides.
-8b < 24
Divide by -8. REVERSE THE SYMBOL!! because dividing by a negative number.
b > -3
graph the equation.
- 5/4 (x-1)(x+3)
Answer:
Step-by-step explanation:
So, to graph a parabola we must have at least 3 points, the x intercepts and the turning point. Currently the equation is in x intercept form which means that we know straight away (assuming the equation =0) that the x intercepts are:
(1,0) and (-3,0)
Now we have to find the turning point and we can do this by putting the equation into turning point form:
-5/4([tex]x^{2} +2x-3[/tex])
-5/4(([tex](x+1)^{2} -3-1[/tex])
-5/4[tex](x+1)^{2}+5[/tex]
Now we can figure out the turning point which is:
(-1,5)
Graph those three points and you should get a parabola shape
