Answer:
It would be 649
Step-by-step explanation:
118 ÷ 2= 59
59 x 11= 649
In any form, the difference is -9 hundredths.
The hundredths place is the second to the right of the decimal point.
0.01 . . . . one hundredth
0.10 . . . . ten hundredths (also known as one tenth)
In ten hundredths, the 1 digit is moved one place to the left, indicating its value is 10 times its value in 0.01.
The difference is 0.01 -0.10 = -0.09, negative nine hundredths.
If you would like to solve 75% of x peaches is 15 peaches, you can calculate this using the following steps:
75% of x peaches is 15 peaches
75% * x = 15
75/100 * x = 15 /*100/75
x = 15 * 100 / 75
x = 20 peaches
Result: 75% of 20 peaches is 15 peaches.
Answer:
A. 20.81 mph
Step-by-step explanation:
x = speed of the boat in still water.
one part of the trip is 10 miles downstream, where the speed of the boat and the speed of the current add together.
and the other part of the trip is the trip back the 10 miles upstream, where the speed of the current works against the speed of the boat :
10/(x + 15) + 10/(x - 15) = 2
10 + 10×(x+15)/(x-15) = 2×(x+15)
10×(x-15) + 10×(x+15) = 2×(x+15)×(x-15)
20x = 2×(x² - 225)
10x = x² - 225
0 = x² - 10x - 225
solution of a quadratic equation
x = (-b ± sqrt(b² - 4ac)) / (2a)
a = 1
b = -10
c = - 225
(10 ± sqrt(100 - 4×1×-225)) / 2 =
= (10 ± sqrt (100 + 900)) / 2 = (10 ± sqrt(1000)) / 2 =
= (10 ± 31.62) / 2
x1 = 41.62 / 2 = 20.81 mph
x2 is negative and did not make any sense.
Answer:
Part A : Total length of Given 3 side = 
Part B : Length of side 4 = 
Part C : Yes, Part A & Part B shows that Polynomials are closed under addition and subtraction
Step-by-step explanation:
Given: Sides of a quadrilateral, Side 1 =
, Side 2 =
,
Side 3 =
.
Perimeter of Quadrilateral = 
To find: [A] Total length of given 3 sides.
[B] Length of Side 4.
[C] Do part A & B show that the polynomials are closed
under addition and subtraction?
Part A -
Total length of Given 3 side = Side 1 + Side 2 + Side 3
= 
= 
=
= 
= 
Part B -
Length of side 4 = perimeter - total length of 3 sides
= 
= 
= 
= 
= 
= 
Part C -
Yes, Part A & Part B shows that Polynomials are closed under addition and subtraction because after addition and subtraction result is also a polynomial.
