Find the sum of all three - digit numbers which give a remainder of 5 when they are divided by 7 immediately
Answer: As Devansh Sehta has calculated, there are 82 terms and 82=7×11+5. When each term of S is divided by 7, the remainders, in order are 6, 3, 0, 4, 1, 5, 2, and these repeat.
Step-by-step explanation:
For any arithmetic sequence, record the remainders when successive terms are divided by n. Then the sum of every set of n consecutive remainders is divisible by 7. In this case, the first 77 terms add to a multiple of 7 as do the 5 remaining terms.

What is percentage?A fraction of 100 is a percentage, also known as percent. Percentage, which is defined as "per 100," represents a fraction of a total sum. 45 out of 100 is what is meant by 45%, for instance. The share of a whole expressed in terms of 100 is discovered when a percentage is calculated. Calculators online or on paper can be used to determine it.
In addition to "out of 100" and "for every 100," the word "percentage" can also be used. You could, for instance, say "it snowed 20% of the time" or "it snowed 20 days out of every 100 days."
Here,
We know that,
A pink gold bracelet weight 60 g has 76% gold, 18% copper and 6% aluminum.
Therefore,
In order to calculate the weight of gold
First we obtain its percentage in bracelet
It's percentage given in question is 76%
Thus,
mass of gold will be 76% of 60g which is 0.76 * 60=45.6g
Therefore ,In pink gold bracelet has a weight of 60 g has 45.6g of gold .

Write an equation in slope-intercept form of the line that passes through the points (2, 15) and (5, 21).
The equation of the line that passes through the points (2, 15) and (5, 21) is y = 2x + 11
The coordinates of the first point = (2, 15)
The coordinates of the second point = (5, 21)
The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the values in the equation
The slope of the line = (21-15) / (5-2)
= 6 / 3
= 2
The slope intercept form is
y = mx + b
Substitute the values
15 = 2(2) + b
15 = 4 + b
b = 15 - 4
b = 11
Substitute the values in the equation
y = 2x + 11
Therefore, the equation of the line in slope intercept form is y = 2x + 11

What is displacement?
Displacement is defined as a change in an object's position. An object's displacement is defined as how far it has moved from its starting point. The dependent variable in the displacement time graph is displacement, which is represented on the y-axis, and the independent variable is time, which is represented on the x-axis. Position-time graphs are another name for displacement time graphs.
The displacement curve is given for 0 ≤ t ≤ 18.
We need to find the total distance of the curve, it will be the positive sum of all displacements.
So, total distance = (7-0) + (3-0) + (2+3) + (2+4) + (7-4)
= 7 + 3 + 5 + 6 + 3
= 24
Hence, the total distance is 24 units.

Tiny's Tattoo Parlor sold 389389 tattoos this month. 4343 of those tattoos were arm tattoos. Based on this data, what is a reasonable estimate of the probability that the next customer does not get an arm tattoo?
If the parlor sold 389389 tattoos and 4343 were arm tattoos, then the probability of next customer does not get an arm tattoos is 0.99
Total number of tattoos sold in this month = 389389 tattoos
Number of arm tattoos = 4343
Number of other tattoos = 389389 - 4343
= 385046
The probability = Number of favorable outcomes / Total number of outcomes
Substitute the values in the equation
The probability of next customer does not get an arm tattoos = 385046 / 389389
Divide the terms
= 0.99

What does a simple interest mean?Simple interest is calculated based on the principal of a loan or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay interest on interest that has already accrued.
How is a simple interest calculated?To calculate simple interest, multiply the principal sum by the time period, interest rate, and time period. Simple interest is calculated as follows: "Simple Interest = Principal x Interest Rate x Time." This equation provides the simplest method for calculating interest.

2x - 5 = width
A = length x width = (x)(2x-5) = 943
2[tex]x^{2}[/tex] - 5x - 943 = 0
use quadratic equation to solve for x:

The fracion 12k⁸/4(k⁵)² expressed in its simplest form is the expression 3/k².
How to simply the expression in fractionTo simplify fraction, we need to factorise the denominator and numerator, and then look for common factors in the numerator and denominator and cancel.
Given the fraction;
12k⁸/4(k⁵)² = 3 × 4 × k⁸/k² × 4 × k⁸ {expressed to get a common factor}
12k⁸/4(k⁵)² = 3 × 4k⁸/k² × 4k⁸
4k⁸ is a common factor to the numerator and denominator, so we cancel it out
