Answer:
165150 is the sum of the multiples of 3 between 100 and 1000.
Step-by-step explanation:
We need to find the sum of multiples of 3 between 100 and 1000.
First we will find the Total number of multiples of 3 between 100 and 1000.
Let a be the first multiple and l be the last multiple of 3
100 is not the multiple of 3.
101 is not the multiple of 3.
102 is the multiple of 3.
Hence first term a = 102
Similarly.
1000 is not a multiple of 3
999 is a multiple of 3
hence last term l = 999
Also d is the common difference.
hence d = 3.
Now by using Arithmetic progression formula we get;
[tex]T_n(l) =a+(n-1)d\\ 999=102+(n-1)3\\999-102=(n-1)3\\897=(n-1)3\\\frac{897}{3}=n-1\\\\n-1=299\\n=299+1\\n=300[/tex]
Hence there are 300 multiples of 3 between 100 and 1000
Now n=300, a=102, l = 999
Hence to find the sum of all the multiples we use the Sum of n terms in AP formula;
Sum of n term [tex]S_n= \frac{n}{2}(a+l)[/tex]
[tex]S_{300}= \frac{300}{2}(102+999)\\\\S_{300}= 150(102+999)\\S_{300}= 150\times 1101\\S_{300}= 165150[/tex]
Hence,165150 is the sum of the multiples of 3 between 100 and 1000.
A company took a survey about its new project. I did the hundred people surveyed, 44 liked the new product. What percentage of the people surveyed like to the new product?
Answer:
The percentage people surveyed like to the new product is 44%.
Step-by-step explanation:
Given:
Company took a survey about its new project, hundred people surveyed, 44 liked the new product.
Now, to find the percentage of the people surveyed like to the new product:
People like new product / Total people surveyed × 100
[tex]\frac{44}{100}\times 100[/tex]
[tex]=0.44\times 100[/tex]
[tex]=44[/tex]

- x - y = 4
x - y = 4
2 x + y = 7
2 x + y = -7
x + y = 4
2 x - y = 7
Answer:
x - y = 4
x + y = 4
Step-by-step explanation:
Substitute x=4 and y=0 in every equation. If both sides of the equal sign are equal, (LS=RS, left side equals right side) then the graph intersects at (4,0).
- x - y = 4
- (4) - 0 = 4
-4 = 4
LS≠RS
x - y = 4
4 - 0 = 4
4 = 4
LS=RS
2 x + y = 7
2(4) + 0 = 7
8 = 7
LS≠RS
2 x + y = -7
2(4) + 0 = -7
8 = -7
LS≠RS
x + y = 4
4 + 0 = 4
4 = 4
LS=RS
2 x - y = 7
2(4) - 0 = 7
8 - 0 = 7
8 = 7
LS≠RS
Only x - y = 4 and x + y = 4 intersect at (4, 0).

Step-by-step explanation:
troop 200 sold cider and donuts to raise money for charity. They sold small boxes of donut holes
for $1.25 and cider for $2.50 a gallon. In order to cover
their expenses they need to raise at least $100. Write and graph an inequality.
Answer:
The equation for the inequality is , c + d = 200
And , $ 2.50 c + $ 1.25 d = $ 100
Step-by-step explanation:
Given as :
The total quantity of cider and donuts for charity = 200
The price of donuts holes =$ 1.25
The price of cider = $ 2.50
The total price money for the cider and donuts = $ 100
Let the quantity of each donuts = d
And The quantity of cider = c
Now, According to question
The total quantity of cider and donuts for charity = 200
Or, The quantity of cider + the quantity of each donuts = 200
Or, c + d = 200 ..........A
And , $ 2.50 c + $ 1.25 d = $ 100 ............B
So, Solving equations
2.50 × ( c + d ) = 2.50 × 200
I.e 2.50 c + 2.50 d = 500
And 2.50 c + 1.25 d = 100
Or, ( 2.50 c + 2.50 d ) - ( 2.50 c + 1.25 d ) = 500 - 100
Or, (2.50 c - 2.50 c ) + ( 2.50 d - 1.25 d ) = 400
Or, 0 + 1.25 d = 400
∴ d = [tex]\frac{400}{1.25}[/tex]
I.e d = 320
The quantity of donuts = 320
Hence The equation for the inequality is , c + d = 200
And , $ 2.50 c + $ 1.25 d = $ 100 Answer
To cover their expenses, the troop needs to raise at least $100. The inequality 2.50x + 1.25y ≥ 100 represents this goal. The primary topic is solving and graphing inequalities in two variables.
Explanation:To write an inequality to represent the troop's goal, we can calculate the minimum amount of money they need to raise. Let x represent the number of gallons of cider sold and y represent the number of boxes of donut holes sold. The total amount of money raised can be given by the inequality 2.50x + 1.25y ≥ 100.
We can graph this inequality on a coordinate plane. Let's assume x represents the horizontal axis and y represents the vertical axis. To graph the inequality, we can first plot the line 2.50x + 1.25y = 100, which represents the equality. Then, since the inequality is ≥, we shade the region above the line to represent all the possible solutions that satisfy the inequality.

Thomas borrowed 4800$ to buy a new car. He will be paying 96$ a each month for the next 60 months. Find the simple interest rate for his car loan.
Final answer:
The simple interest rate for Thomas' car loan is 3.33%.
Explanation:
To find the simple interest rate for Thomas' car loan, we need to use the formula for simple interest:
Simple Interest = Principal x Rate x Time
In this case, the principal (amount borrowed) is $4800 and the monthly payment is $96. The time is 60 months. We can rearrange the formula to solve for the rate:
Rate = Simple Interest / (Principal x Time)
Plugging in the values:
Rate = 96 / (4800 x 60) = 0.0003333
So, the simple interest rate for Thomas' car loan is 0.03333 or 3.33%.

A wooden beam is left parenthesis 6 y squared plus 5 y plus 1 right parenthesis6y2+5y+1 meters long. If a piece of length left parenthesis y squared minus 12 right parenthesisy2−12 meters is cut off, express the length of the remaining piece of beam as a polynomial in y.
Answer:
5y² + 5y - 11
Step-by-step explanation:
The length of a wooden beam is as a function of y
L(y) = 6y² + 5y + 1
and a piece of length y² - 12 is cut off the remaining piece is
6y² + 5y + 1 - y² - 12 = 5y² + 5y - 11
To find the remaining length of the wooden beam, subtract the length of the cut-off piece from the original polynomial. Simplify the expression to get the final answer: 5y² + 5y + 13 meters. This represents the remaining length of the beam.
Finding the Remaining Length of the Wooden Beam:
We start with the original length of the wooden beam given by the polynomial 6y² + 5y + 1 meters.
We need to subtract the length of the piece that was cut off, which is given by the polynomial y² - 12 meters.
First, write down the original length of the beam:
6y² + 5y + 1
Next, identify the length of the piece cut off:
y² - 12
Subtract the second polynomial from the first:
(6y² + 5y + 1) - (y² - 12)
Simplify the expression by combining like terms:
6y² - y² = 5y²
5y remains unchanged.
1 - (-12) = 1 + 12 = 13
So, the remaining length of the beam is:
5y² + 5y + 13
The remaining length of the wooden beam, expressed as a polynomial in y, is 5y² + 5y + 13 meters.

In ∆ABC the angle bisectors drawn from vertexes A and B intersect at point D. Find ∠ADB if:
m∠C = γ
Answer:
155°
Step-by-step explanation:
In Δ ABC, let A = x°
By Angle-sum property,
A + B + C = 180°
But, it is given that C = 130°
So, x + B + 130 = 180
B = 180 - 130 - x
B = 50 - x
Since AD and BD are internal bisectors of A and B,
∠ DAB = x/2 and
∠ DBA =
In Δ ADB, by angle-sum property,
∠ DBA + ∠ DAB +∠ ADB = 180°
+ ∠ ADB = 180°
25 + ∠ ADB = 180°
∠ ADB = 180 - 25 = 155°
Hence, ∠ ADB = 155°
INEQUALITIES-PLEASE HELP! Tricia receives a $5 allowance every week. She also earns $6.50 for every hour that she baby-sits. Next week she wants to earn at least $21.25 to buy a present. Please write an inequality to math this equation.
Answer:
6.50x + 5 = 21.25 is the answer
Step-by-step explanation:
x=2.5
The inequality that represents Tricia's goal to earn at least $21.25 through her $5 allowance and $6.50 per hour from babysitting is E = 5 + 6.50h ≥ 21.25, where h represents the number of hours she babysits.
The student's question asks for an inequality to represent the situation where Tricia receives a $5 weekly allowance and earns $6.50 for each hour she babysits. The goal is to earn at least $21.25 to buy a present.
Let's denote the number of hours Tricia babysits as h. The inequality representing her total earnings E from both her allowance and babysitting will be:
E = 5 + 6.50h ≥ 21.25
This inequality implies that the sum of Tricia's weekly allowance ($5) and her babysitting earnings ($6.50 per hour multiplied by the number of hours h) should be at least $21.25.
Thomas rents a car for his vacation. The mileage include with the rental is 54 miles. For every mile he drives over 54 miles, he needs to pay $1 4/5. If he drives 69 miles, how much extra does he need to pay?
Answer:
Thomas needs to pay additional US$ 27 for the 15 extra miles not included in the mileage.
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Mileage included with the rental = 54 miles
Additional mile over 54 miles = US$ 1 4/5
Distance finally driven by Thomas = 69 miles
2. Let's calculate how much additional money Thomas needs to pay.
Extra miles driven by Thomas = Distance finally driven - Mileage included
Extra miles driven by Thomas = 69 - 54
Extra miles driven by Thomas = 15
Cost of the additional miles = 15 * 1 4/5
Cost of the additional miles = 15 * 1.80 ⇒ 4/5 = 0.80
Cost of the additional miles = 27
Thomas needs to pay additional US$ 27 for the 15 extra miles not included in the mileage.

Step-by-step explanation:

To solve the given system of inequalities, we can solve each inequality separately and then find the intersection of their solution sets. The solution set is x≤5.
Explanation:To solve the given inequality 3x-8≤23 or -4x+26≥6, we can solve each inequality separately and then find the intersection of their solution sets.
For the first inequality, 3x-8≤23, we add 8 to both sides and then divide by 3 to isolate x: 3x≤31, x≤31/3.
For the second inequality, -4x+26≥6, we subtract 26 from both sides and then divide by -4 to isolate x: -4x≥-20, x≤5.
Since x must satisfy both inequalities, the solution set is x≤5 and x≤31/3. Taking the smaller value, we have x≤5.
A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 2 large boxes and 6 small boxes has a total weight of 128 kilograms. A delivery of 5 large boxes and 3 small boxes has a total weight of 137 kilograms. How much does each type of box weigh?
The weight of a large box is 18.25 kilograms and the weight of a small box is 15.25 kilograms.
Explanation:Let's use a system of equations to solve this problem. Let's assume the weight of a large box is 'x' and the weight of a small box is 'y'. Based on the given information, we can set up the following equations:
2x + 6y = 128 (equation 1)5x + 3y = 137 (equation 2)Now, we can solve this system of equations to find 'x' (the weight of a large box) and 'y' (the weight of a small box).
We can start by multiplying equation 1 by 5 and equation 2 by 2 to eliminate 'x':
10x + 30y = 640 (equation 3)10x + 6y = 274 (equation 4)Subtracting equation 4 from equation 3:
24y = 366
Simplifying:
y = 15.25
Substituting the value of 'y' back into equation 1 or 2, we can solve for 'x':
2x + 6(15.25) = 1282x + 91.5 = 1282x = 128 - 91.52x = 36.5x = 18.25Therefore, a large box weighs 18.25 kilograms and a small box weighs 15.25 kilograms.

Find the distance between point A (-9,-3) to line y = x - 6. Round your answer to the nearest tenth.
The distance from the point A(-9,-3) to the line y = x - 6 is calculated using the formula for the distance from a point to a line in the coordinate plane. After substituting the values in the formula, the distance is approximately 8.5 units.
Explanation:To find the distance from point A (-9,-3) to the line y = x - 6, we use the formula for the distance from a point to a line in two-dimensional space. This formula is |Ax1+ By1 + C| / sqrt(A^2 + B^2), where (x1,y1) is the point and Ax+By+C=0 is the equation of the line.
Firstly, we need to rewrite our given equation in the standard form. The equation y = x - 6 becomes x - y - 6 = 0. Therefore, A=1, B=-1, and C=-6.
Substitute A, B, C and the coordinates of point A into the formula, we get the distance as |[1*(-9) - 1*(-3) - 6]| / sqrt((1)^2 + (-1)^2) = |-12| / sqrt(2) = 8.48, rounding this to the nearest tenth, we get 8.5.

The distance from the point A (-9,-3) to the line y = x - 6 is approximately 4.2 units when rounded to the nearest tenth.
Explanation:You asked to find the distance between point A (-9,-3) to the line y = x - 6. The formula to find the shortest distance, d, from a point to a line is given by the absolute value of |Ax1 + By1 + C| divided by the square root of A squared plus B squared, where (x1, y1) are the coordinates of the point and the line equation can be written in the standard form as Ax + By + C = 0. In this case, A = 1, B = -1, C = 6 (because y - x = 6 can be re-written as y - x - 6 = 0). Plugging in the coordinates of point A and the values of A, B, and C into the formula, we get |1*(-9) + -1*(-3) + 6| divided by the square root of [tex](1)^2 + (-1)^2[/tex], which simplifies to |-6| divided by the square root of 2, or 6 divided by sqrt(2). Converted to a decimal and rounded down, this equals approximately 4.2 units. Therefore, the distance from the point to the line is 4.2 units, rounded to the nearest tenth.
