kPLEASE SOMEONE SOLVE B) I ALREADY KNOW 1. A) Is 75.875m^2
The answer to part A is correct. You basically have to find the area of that L shape, and subtract off the area of the shaded trapezoid.
To get part B, you need to find the perimeter. This is because the trim runs along the bottom edge of the wall. Refer to the diagram below. Adding up the exterior sides gets us:
12+12+4+8+8+4 = 48
So she needs 48 meters of trim.
I'm not sure what your teacher means by "what assumptions do you make". If your teacher is referring to something like making room for a door, then we'll have to subtract some value from that 48. The problem with this though is that we don't have any clue how wide the door is. So you'll have to ask your teacher for clarification.
Luckily, this value 48 is an overestimate of the amount of trim Jennifer needs to buy. In my opinion, it's better to overestimate than underestimate, which saves from having to make another trip to the hardware store.

Navel Laser and Midoriya are doing target practice. In the first round Navel laser scored no points, but in the second round he scored “x” amount of points. In their third round, he scored 8 more points than the second. Now in the last round, he scored three times as many points as the third. Altogether Navel Laser scored 117 points!!! How many points did the Navel Laser score in each round?
Answer:
Round 1 = 0 points
Round 2 = 17 points
Round 3 = 25 points
Round 4 = 75 points
Step-by-step explanation:
Determine how many points will be scored in each round in correspondence to the variable 'x':
Round 1:
0(x)
Round 2:
x
Round 3:
x+8
Round 4:
3(x+8)
We know that the sum of all points made in all rounds is 117. Using this information, we can make an equation:
0(x)+x+(x+8)+[3(x+8)]=117
Now, we solve for x:
x+x+8+3x+24=117
5x+32=117
5x=117-32
5x=85
[tex]\frac{5x}{5} =\frac{85}{5}[/tex]
x=17
Now we substitute the calculated value for x in each round:
Round 1:
0(17)=0
Round 2:
(17)=17
Round 3:
(17)+8= 25
Round 4:
(25)*3= 75
please finish this equation and write the answer
Given:
The equation is:
[tex]2540=\dfrac{22}{7}r^2(20)[/tex]
To find:
The solution for the given equation.
Solution:
We have,
[tex]2540=\dfrac{22}{7}r^2(20)[/tex]
It can be written as:
[tex]\dfrac{2540\times 7}{22\times 20}=r^2[/tex]
[tex]\dfrac{17780}{440}=r^2[/tex]
[tex]\dfrac{889}{22}=r^2[/tex]
Taking square root on both sides, we get
[tex]\sqrt{\dfrac{889}{22}}=r[/tex] [Radius cannot be negative]
[tex]r=6.3568145[/tex]
[tex]r\approx 6.36[/tex]
Therefore, the value of r is about 6.36 cm.

Answer:
29.5 square inches
Step-by-step explanation:
Let's divide the shape into 3 parts to make it easy for us to find the area.
- a wide triangle
- a triangle
- a shorter rectangle
For the wider rectangle, the area is;
A1 = 8 × 2 = 16 in²
For the triangle, the area is;
A2 = ½(7 - 2) × 3
A2 = 7.5 in²
For the shorter rectangle, the area is;
A3 = 3 × 2
A3 = 6 in²
Total area = A1 + A2 + A3 = 16 + 7.5 + 6 = 29.5 square inches
whats the area of this shape?
Answer:
54
Step-by-step explanation:
find the area of each shape. you have a length of 3 and a height of 4.
3 • 4 = 12
you have this shape twice so 12 • 2 = 24
now you have a length of 5 and a height of 6.
5 • 6 = 30
so adding up all of the numbers (24 + 30), you have an answer of 54.

The value of a two digit number whose units digit is u and the sum of the digits is 7
write an algebraic expression
Answer:
The expression is 70 - 9 u .
Step-by-step explanation:
Digit at ones place = u
Let the digit at tens place is y.
Sum of the digits is 7.
y + u = 7
y = 7 - u
So, the number is
10 y + u
= 10 (7 - u) + u
= 70 - 10 u + u
= 70 - 9 u

Answer:
750kmph
Step-by-step explanation:
Average is sum of all parts divided by the number of parts.
Let Stot be average speed for total trip (800kmph).
Let S1 be speed for first quarter of trip (950kmph).
Let S2, S3, and S4 be the speeds of each of the remaining quarters respectively.
Let Sans be the average speed for the remaining three quarters of the trip (a.k.a. The Answer!).
Stot = (S1 + S2 + S3 + S4) / 4
800kmph = (950kmph + S2 + S3 + S4) / 4
3200kmph = 950kmph + S2 + S3 + S4
3200kmph - 950kmph = 2250kmph = S2 + S3 + S4
Divide both sides by 3.
2250kmph / 3 = (S2 + S3 + S4) / 3 = Sans
Sans = 750kmph

Express this to single logarithm
[tex] \frac{1}{2} log_{2}(m) - 3 log_{2}(n) + 2 log(q) [/tex]
Answer: [tex]\log_{2}\left(\frac{q^2\sqrt{m}}{n^3}\right)[/tex]
We have something in the form log(x/y) where x = q^2*sqrt(m) and y = n^3. The log is base 2.
===========================================================
Explanation:
It seems strange how the first two logs you wrote are base 2, but the third one is not. I'll assume that you meant to say it's also base 2. Because base 2 is fundamental to computing, logs of this nature are often referred to as binary logarithms.
I'm going to use these three log rules, which apply to any base.
log(A) + log(B) = log(A*B)log(A) - log(B) = log(A/B)B*log(A) = log(A^B)From there, we can then say the following:
[tex]\frac{1}{2}\log_{2}\left(m\right)-3\log_{2}\left(n\right)+2\log_{2}\left(q\right)\\\\\log_{2}\left(m^{1/2}\right)-\log_{2}\left(n^3\right)+\log_{2}\left(q^2\right) \ \text{ .... use log rule 3}\\\\\log_{2}\left(\sqrt{m}\right)+\log_{2}\left(q^2\right)-\log_{2}\left(n^3\right)\\\\\log_{2}\left(\sqrt{m}*q^2\right)-\log_{2}\left(n^3\right) \ \text{ .... use log rule 1}\\\\\log_{2}\left(\frac{q^2\sqrt{m}}{n^3}\right) \ \text{ .... use log rule 2}[/tex]

If a polynomial function has n degree, then it can have at most (n - 1) ____________ in the graph.
9514 1404 393
Answer:
turning points
Step-by-step explanation:
The number of turning points is the number of real zeros in the derivative polynomial. As you know, the number of real zeros of a polynomial is at most the polynomial degree.
The degree of the derivative is always 1 less than the degree of the polynomial. So, a polynomial of degree n will have at most (n-1) turning points.
