The legth of a rectangle is 15 inches less then twice its width, w. If the perimeter of the rectangle is 96 inches what is the length of a rectangle?
Answers
Answer:
length of the rectangle=27"
Step-by-step explanation:
length be = l; width be = b
2b-15= l
perimeter= 2(l+b)
=2(2b-15+b)=96
=2(3b-15) =96
3b-15 .=48
3b=48+15=63
b=21. Therefore l = (2 x 21) - 15=42-15 =27"
Six multiplication problems involved in solving 325 x 89
Answers
Answer:
(300*80) + (300*9) + (20*80) + (20*9) + (5*80) + (5*9) = 28925
Step-by-step explanation:
Given;
325 x 89
Expand 325 = 300 + 20 + 5
Expend 89.0 = 80 + 9
now multiple to two expanded numbers;
(300 + 20 + 5) x (80 + 9)
distribute the number accordingly as follows;
(300*80) + (300*9) + (20*80) + (20*9) + (5*80) + (5*9), now we have Six multiplication problems.
= 24,000 + 2700 + 1600 + 180 + 400 + 45
= 28925
What is wrong with this "proof"?"Theorem" For every positive integern, ifxandyare positive integers with max(x, y) =n,thenx=y.Basis Step: Suppose thatn= 1. If max(x, y) = 1 andxandyare positive integers, we havex= 1 andy= 1.Inductive Step: Letkbe a positive integer. Assume that whenever max(x, y) =kandxandyare positive integers, thenx=y. Now let max(x, y) =k+ 1, wherexandyare positiveintegers. Then max(x−1, y−1) =k, so by the inductive hypothesis,x−1 =y−1. Itfollows thatx=y, completing the inductive step.
Answers
Answer:
Every step is wrong in the proof theorem
Step-by-step explanation:
The inductive step : whenever max(x, y) = k and x and y are positive integers, then x = y. is wrong because
If max (x,y ) = k + 1 then max ( x-1, y-1 ) = k
and by inductive hypothesis : x-1 = y-1 and x =y
example :
max ( 2, 3 ) = 3 where x = 2 , y =3
and x ≠ y hence the inductive step is wrong
A designer is creating various open-top boxes by cutting four equally-sized squares from the corners of a standard sheet of 8.5 inch by 11 inch paper, and then folding up and securing the resulting 'flaps' to be the sides of the box. Let x represent the varying side length of the square cutouts in inches. Let l , w , and h represent the varying length, width and height of the box (in inches), respectively. Note that the width and length dimensions are such that w < l . Let V represent the varying volume of the box in cubic inches. Write formulas for length, width, and volume of the box, each in terms of x .
Answers
Answer:
L(x) = 11 - 2x
W(x) = 8.5 - 2x
V(x) = 4x³ - 39x² + 93.5x
Step-by-step explanation:
If a square of x sides length is cut from each corner of the sheet, then it meas the length and width of the box a shortened by x inces from each side, giving a total subtraction of 2 times x inches.
FORMULA FOR LENGTH:
Since, Length is the bigger side of the box. Therefore, it will be taken on 11 inches side of the paper:
L(x) = 11 - 2x
FORMULA FOR WIDTH:
Since, width is the smaller side of the box. Therefore, it will be taken on 8.5 inches side of the paper:
W(x) = 8.5 - 2x
FORMULA FOR VOLUME:
Volume is the product of length, width and time:
V(x) = L(x)*W(x)*H(x)
Height must be equal to the side folds which are equal to length of the side of square = x:
H(x) = x
Therefore,
V(x) = (11 - 2x)(8.5 - 2x)(x)
V(x) = (93.5 -22x -17x + 4x²)(x)
V(x) = 4x³ - 39x² + 93.5x

make a second equation because you multiply by 100:
100x = 61.616161 (etc.)
subtract from each other
100x = 61.616161
x = 0.616161

The second angle of a triangle is twice as large as the first angle. The third angle is 35 greater than the second angle. How large is the first angle?
Answers
Answer:
29°
Step-by-step explanation:
Let x represent the first angle. Then the second angle is 2x, and the third angle is 2x+35°. The sum of the angles is 180°, so we have ...
x + 2x + (2x+35) = 180
5x +35 = 180 . . . . collect terms
x +7 = 36 . . . . . . . divide by 5
x = 29 . . . . . . . . . . subtract 7
The first angle is 29°.

in one week katy walks 1,720 meters and runs 1,925 meters. she performs the same workouts for three weeks. how many meters does katy walk and run in three weeks of workouts?
Answers
Answer:
10,935 meters.
Step-by-step explanation:
Find how many meters she walks in 1 week, so you add the 1,720 and the 1,925 and you would get 3,645. If she does the same thing for 3 weeks, you multiply the 3,645 by 3, so you get 10,935 meters

Sam takes a sheet of paper and cuts from one corner to the opposite

the paper is 22 inches long, what is the width of the sheet of paper
(nearest tenth)?
41 in
22 in
width
Answers
Answer:
The width is 34.6
Step-by-step explanation:
You have to assume that the cut is a straight cut.
Givens
c = 41
a = 22
b = ?
Formula
a^2 + b^2 = c^2
Solution
22^2 + b^2 = 41^2
484 + b^2 = 1681 Subtract 484 from both sides
484-484 + b^2 = 1681-484 Combine
b^2 = 1197 Take the square root of both sides.
sqrt(b^2) = sqrt(1197)
b = 3*sqrt(133)
b = 34.598
b = 34.6

The scale of a map is 6 km = 4 mi. What is the length on the map if the actual is 40.1
miles.
Answers
Answer:
60.15 km
Step-by-step explanation:
If 6 km on the map represents 4 mi on land, then we'd get the answer by using the relation
6 km -> 4 mi
x km -> 40.1 mi
Where x km is the length on the map we're looking for. If we cross multiply
6 * 40.1 = 4x
240.6 = 4x
x = 240.6/4
x = 60.15 km.
That is the length we're looking for

Answer:
9
Step-by-step explanation:
Notice that 27 can be factored out as 3 * 3 * 3
and 12 can be factored out as: 2 * 2 * 3
then when we study the ratio 27/12, we can cancel out a factor 3, leaving us with: (3 * 3) / (2 * 2) = 9 / 4
Then 9 is the number you need to type in the box.
