Step-by-step explanation:
let the amount that Krutika gets be x, therefore, gets him the amount that jim get will be x +40
therefore 3/1=x+40/x
hence 3x=x+40
therefore x=40/2
x=20
Step-by-step explanation:
let the amount that Krutika gets be x, therefore, gets him the amount that jim get will be x +40
therefore 3/1=x+40/x
hence 3x=x+40
therefore x=40/2
x=20
Rapid Rental Car charges a $55 rental fee, $20 for gas, and $0.65 per mile driven. For the same car, Capital Cars charges $55 for rental and gas and $0.75 per mile.
Answer:
200 miles
Step-by-step explanation:
Given data
Rapid Rental Car
charges a $55 rental fee
$20 for gas, and
$0.65 per mile driven
let the number of miles be x, the total charges y
y=55+20+0.65x
y= 75+0.65x----------1
Capital Cars
charges $55 for rental and gas and
$0.75 per mile.
let the number of miles be x, the total charges y
y=55+0.75x
y= 55+0.75x----------2
Required
The number of miles driven before the two Rental companies charge the same amount
equate 1 and 2
75+0.65x= 55+0.75x
collect like terms
75-55= 0.75x-0.65x
20= 0.1x
x= 20/0.1
x= 200miles
Hence the distance will be 200 miles for the charges to be the same

Libby earns $10 each hour for babysitting. Let m = the money she earns, and t = the time in hours she is babysitting. What equation represents this proportional relationship?
Answer:
$10t=m
Step-by-step explanation:
If for each hour is $10.
She would earn the number of hours times $10.
Example: She did babysitting for 4 hours this weekend. The equation is $10(4)=m or $10 x 4 = m. m=40
Explain why the product of a non-0 rational number and an irrational number is irrational?
Answer:
An irrational number is a number that can not be written as the quotient of two integer numbers.
Then if we have:
A = a rational number
B = a irrational number.
Then we can write:
A = x/y
Then the product of A and B can be written as:
A*B = (x/y)*B
Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.
(x/y)*B = (m/n)
If we isolate B, we get:
B = (m/n)*(y/x)
We can rewrite this as:
B = (m*y)/(n*x)
Where m, n, y, and x are integer numbers, then:
m*y is an integer
n*x is an integer.
Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.
Then the product of an irrational number and a rational number different than zero is always an irrational number.
We need to add the fact that the rational number is different than zero because if:
B is an irrational number
And we multiply it by zero, we get:
B*0 = 0
Then the product of an irrational number and zero is zero, which is a rational number.

SHOW YOUR WORK!!!
Answer:
45/8 or 5 5/8
Step-by-step explanation:
2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8. you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.
Answer:
45/8 or 5 5/8
Step-by-step explanation:
When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.
Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.
Numerators: 9 x 5 = 45
Denominators: 4 x 2 = 8
So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.
I don't know how you wanted me to show my work, but I tried the best I could to explain.

Step-by-step explanation:
Given
5x + 2y = 16 .....i)
x + 2y = 4 .....ii)
Subtracting equation I) and ii) we get
5x + 2y = 16
x + 2y = 4
- - -
4x = 12
x = 3
Putting x = 3 in equation ii)
3 + 2y = 4
2y = 4 - 3
y = 1/2
x =3 and y = 1/2
Hope it helps :)

If the circle below is cut from the square of plywood below, how many square inches of plywood would be left over? Use π = 3.14, and round your answer to the nearest hundredth
Answer:
86in²
Step-by-step explanation:
Find the complete question attached
Area of the circle = πr²
Area of the square = L²
Length of the side of the square
r is the radius of the circle
r = L/2 = 20/2 =10in
Given
Length of the side of the circle = 20in
Area of the square = 20²
Area of the square = 400in²
Area of the circle =π(10)²
Area of the circle = 3.14(100)
Area of the circle= 314in²
Amount of plywood left over = 400in²-314in² = 86in²
Which of these expressions is equivalent to log (92)? O A. log (2) • log (9) O B. log (2) – log (9) OC. log (2) + log (9) OD. 2 • log (9)
Correct question is;
Which of these expressions is equivalent to log (9^2)?
Answer:
D: 2•log 9
Step-by-step explanation:
From log rules, we know that;
log(a^n) = n•log(a)
Applying that rule to this question, we can simplify log (9^2) as;
log (9^2) = 2•log 9
Looking at the options, the correct one is Option D
What is the surface area
Answer:
red) area = 59.2 km²
Step-by-step explanation:
area of bottom 4 x 4 = 16
area of 4 sides = 4 (1/2)(4)(5.4) = 43.2
16 + 432 = 59.2 km²
Answer:
Step-by-step explanation:
lateral area = 2(base)(slant height) = 2·4·2 = 16 km²
base area = base² = 4² = 16 km²
surface area = 16 + 16 = 32 km²

Answer:
slope: 2/3 or 0.6666...
Step-by-step explanation:
find two points on the line : (1,2) and (0,-2) and do rise over run. Rise = 2 and Run = 3, so you put it in rise over run form. Rise/Run = 2/3. The graph is positive.
Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4
Answer:
y =-5x + 7
Step-by-step explanation:
y = -5x + 4
Slope = -5
Parallel lines have same slope
Slope of the parallel line to this line = -5
(1 , 2)
y -y1 =m(x - x1)
y - 2 = -5(x - 1)
y -2 = -5x + 5
y = -5x + 5 + 2
y = -5x + 7

2. a) Write the next two terms of the following sequence and write the rule. ( /3)
11, 15, 19, 23, 27, ______, ______
Rule: ___________________________________________________
b) Write an example of a Fibonacci sequence.
__________________________________________________________ no wronge ans or report
Answer:
See answers below
Step-by-step explanation:
Given the sequence
11, 15, 19, 23, 27, ______, ______
nth term is expressed as Tn = a +(n-1)d
a= 11
d = 15-11 = 19-15 = 4
n = 6 and 7
for the sixth term,
T6 = 11 +5d
T6 = 11 + 5(4)
T6 = 20
for the 7th term,
T7 = 11 +6d
T7 = 11 + 6(4)
T7 = 11+24
T7 = 35
Rule used Tn = a + (n-1)d
b) Example of a Fibonacci sequence is 1,1, 2, 3, 5, 8, 11...
The sum of the two previous term of a Fibonacci sequence gives the next term. That is how the sequence was constructed

Five less than twice the value of a number is equal to three times the quantity of four more than ½ the number. What is the number?
Step-by-step explanation:
(2x-5) = 3(4+x/2) then solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x=34
Checking the left side, (2x-5) = 2(34) - 5 = 63.
Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.
