Answer:
The report is 960 words long.
Step-by-step explanation:
The handwritten book report is 4 pages long and the typed report is 3 pages long.
Now, it is given that typing at a steady rate of 20 words per minute, it takes 48 minutes to enter the report into soft copy.
So, the required number of words of the report is (20 × 48) = 960 words.
Hence, the report is 960 words long. (Answer)
Answer:
p = 10.8
Step-by-step explanation:
Given that p is directly proportional to (p-1)² and p is always positive, then;
q = k (p-1)²
If q = 30 and p = 7
30 = k(7-1)²
30 = 6²k
30 = 36k
5 = 6k
k = 5/6
To get p when q = 80
q =k (p-1)²
80 = 5/6((p-1)²
480 = 5(p-1)²
480/5 = (p-1)²
(p-1)² = 96
p-1 = √96
p-1 = 9.8
p = 9.8 + 1
p = 10.8

By definition, the area is given by:
A = w * l
Where,
w: width
l: length
We have two expressions for the length:
L = 14\\L = 5 + 3c
Since the length is the same, we equate both expressions:
5 + 3c = 14
From here, we clear the value of c:
3c = 14 - 5\\3c = 9
c = \frac{9}{3}\\c = 3
Then, we have that the width is given by:
W = 6c-8
Substituting the value of c we have:
W = 6 (3) -8\\W = 18-8\\W = 10
Finally, the area is given by:
A = w * l\\A = 10 * 14\\A = 140 ft ^ 2
Answer:
he should order 140 square feet
25. 3y+15
26. 15k+20
27. 21n+7p
28. 60w+20x
Also, you got number 19, number 21, and number 24 wrong.
D+D+D+D+D = 5D, not D⁵
S+S+S = 3S, not S³
N+N+N+N = 4N, not N⁴
Remember, repeated addition, (n+n+n) is 3n. Repeated multiplication, (n•n•n) is n³.
Hope this helps.
Do you know how to use calculator to find fast answer?
1) press mode 3 times
2)then u find 'EQN'then press 1
3)then u can see 'UNKNOWS'but dont use the 'UNKWOWS' you must press to tge right i u can see 'DEGREE' then if you already find the DEGREE you press number 2
4)Then the 'a?' will out u can put 1 stand for X^2 then equal
5) next the 'b?' come out you put 6 stand for 6x then equal
6)final the 'c?'will come out and you put -27 then equal
7) then the answer will come out
it will be x1=3 and x2=-9
8) but if you want to put in bracket the x1=will be -3 and the x2= will be 9
so final answer
(x-3)(x+9)
