The fraction 5/3 as a mixed number is [tex]1\frac{2}{3}[/tex].
To write the fraction 5/3 as a mixed number, we need to find the whole number and the proper fraction parts.
A mixed number is a combination of a whole number and a proper fraction (where the numerator is smaller than the denominator).
Divide the numerator (5) by the denominator (3).
5 ÷ 3 = 1 with a remainder of 2
The quotient (1) represents the whole number part, and the remainder (2) becomes the numerator of the proper fraction.
The denominator remains the same, which is 3.
Hence, the mixed number representation of 5/3 is [tex]1\frac{2}{3}[/tex].

Step-by-step explanation:
The cookies in a jar contain a total of 1000 chocolate chips. All but one of these cookies contains the same number of chips; it contains one more chip than the others. The number of cookies in the jar is between one dozen and three dozen. What is the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip? (Hint: using factorization) (A) 65 (B) 64 (C) 63 (D) 66 (E) 67
Answers
Answer:
65
Step-by-step explanation:
From the given information:
Let consider p to be the total numbers of the cookies
If there are 1000 chocolate chips in the jar;
The number of chocolate chips if we remove one chocolate chips = 1000 -1
= 999
The number of available choco chips on each cookie except for the one having an extra chocolate chip = 999/p
Thus, to achieve a whole number, p is required to be a factor of 999
By factorization of 999, we get:
36 > p > 12; Thus, the value for "p" lies between 36 and 12, and which must be by 999 is 27
Thus, the number of cookies in the jar "p"= 27
However, the number of chocolate chips on with the extra chocolate chip
= 999/p + 1
= 999/27 + 1
= 37 + 1
= 38
Thus, the sum of the number of cookies in the jar + the number of chocolate chips on with the extra chocolate chip
= 27 + 38
= 65

How much does a t-shirt cost?
How much does a hat cost
Answers
Answer:
a T-shirt costs £5
a hat costs £2
Step-by-step explanation:
Suppose
A T-shirt=x
A Hat=y
So the equation is
8x+y=42
3x+y=17
So
8x+y=42
3x+y=17
------------
5x=25
x=5
So a T-shirt costs £5
3.5+y=17
15+y=17
y=2
So a hat costs £2
Answer:
t-shirt: £5
hat: £2

Write the power set of the set A={a,b,c}
Answers
Answer:
P(A) = {{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅}
Step-by-step explanation:
➨ Power Set is the set of all subsets.
First, find the subset of A.
{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅
If you aren't sure that you already have written all subsets or not, use the following formula.
[tex]2^n[/tex] ➩ where n is the number of element/members.
Our number of members are 3, use the following formula.
[tex]2^3=8[/tex]
Thus, our subsets should be 8.
As we've already gathered all subsets, write the braces all whole subsets.
P(A) = {{a},{b},{c},{a,b},{a,c},{b,c},{a,b,c},∅}

$4 + $4 + $4 + $4 = 16, so Sal can afford the gas.
$3 + $3 + $3 + $3 = 12, so Sal cannot afford the gas.

"What is the equation of the line parallel to the given line with an x-intercept of 4?"
y = __x + __
Answers
In the form y=mx+b, m is the slope, so the slope of this new line is y=4x+b.
The x intercept is 4, which is the coordinate (4,0). So plug that in to get b:
0=4(4)+b
0=16+b
B=-16
So in total, the new line is y=4x-16.

Randy wants to attach a 23 foot string of lights to the top of the 13 foot mast of his sail boat. How far from the base of the mast should he attach the end of the light string?
Answers
Answer:
distance from the base where string is attached = 18.97 feet
Step-by-step explanation:
The diagram attached to this solution gives a right-angled triangle formed by attaching the string to the top of the mast. the distance from the base is calculated as follows:
(hypotenuse)² = (opposite)² + (adjacent)²
23² = 13² + d²
529 = 169 + d²
d² = 529 - 169
d² = 360
d = √(360)
d = 18.97 feet

Over 3 days Molly earns $2,568 for a local charity.She earns twice as much money on the first day then the second day. She earns 3 times as much money than the second day on the 3rd day.How much money did Molly earn on the first day?
Answers
Answer:
Molly earned $856 on the first day.
Step-by-step explanation:
From the information given, you know that over 3 days Molly earned $2,568 which is:
x+y+z=2568, where:
x is the amount earned on the first day
y is the amount earned on the second day
z is the amount earned on the third day
Also, you know that she earns twice as much money on the first day then the second day, which is: x=2y and that she earns 3 times as much money than the second day on the 3rd day, which is: z=3y.
Now you can replace x and y in the first equation and solve for y:
2y+y+3y=2568
6y=2568
y=2568/6
y=428
No, you can replace the value of y to find x and z:
x=2(428)
x=856
z=3(428)
z=1284
According to this, the answer is that Molly earned $856 on the first day.
