I am three years younger than my brother and I am two years older than my sister my mom's age is 1 less than three times my brothers age when you add all these ages up you get 87 what are our ages
Answers
Answer:my age = 13years,My brother's age =16years,My sister's age=11years,my mom's age =47years
Step-by-step explanation:
Step 1
Let my age be represented as x
My brother's age be represented as x+3
My sister's age =x-2
and my mum's age be 3(x+3)-1 with the total of all our ages = 87 Giving us the equation
x+ x+3+ x-2+ 3(x+3)-1 = 87
Step 2 ---Solving
x+ x+3+ x-2+ 3(x+3)-1 = 87
x+ x+3+ x-2+ 3x+9 -1 = 87
6x + 9= 87
6x= 87-9
6x= 78
x =78/6 = 13
Therefore my age = 13years
My brother's age = x+ 3 = 13+3= 16years
My sister's age = x-2 =13-2 = 11years
my mom's age = 3(x+3)-1= 3(13+ 3)- 1= 3 x 16 - 1 = 47years

Hi, I need help with the EXPLANATION of this question. I have the right answer, but I am unsure why. 50 POINTS
Answers
Step-by-step explanation:
Using Pythagoras' Theorem, we have
x² + 10² = (12√3)²
Therefore x² = (12√3)² - 10²
= (144)(3) - (100) = 332.
=> x = √332 = 2√83. (B)
Residents of three counties were polled to find the percentage of residents who are Republican or Democrat. A 4-column table with 4 rows. The first column has no label with entries county 1, county 2, county 3, total. The second column is labeled Democrat with entries 4,050; 3,925; 2,100; 10,075. The third column is labeled Republican with entries 2,470; 6,010; 5,950; 14,430. The fourth column is labeled total with entries 6,520; 9,935; 8,050; 24,505. Find the following relative frequencies to the nearest tenth of a percent. Republican residents of County 1: % Democratic residents of County 1: % Total Republican residents: % Total Democratic residents: %
Answers
Using the concept of relative frequency, it is found that:
Republican residents of County 1: 37.9%.Democratic residents of County 1: 62.1%.Total Republican residents: 58.9%.Total Democratic residents: 41.1%.----------------------------------
A relative frequency is the number of desired outcomes divided by the number of total outcomes.
To find it as a percentage, we multiply by 100%.
----------------------------------
The table used is the image at the end.
----------------------------------
County 1 has 6,520 residents, out of which 2,470 are Republican.
2470*100%/6520 = 37.9%
Thus:
Republican residents of County 1: 37.9%.
----------------------------------
County 1 has 6,520 residents, out of which 4,050 are Democratic.
4050*100%/6520 = 62.1%
Thus:
Democratic residents of County 1: 62.1%.
----------------------------------
Total of 24,505 Residents, 10,075 Democrats and 14,430 Republicans.
10075*100%/24505 = 41.1%
14430*100%/24505 = 58.9%
Thus:
Total Republican residents: 58.9%.
Total Democratic residents: 41.1%.

Answers
Answer:
4 1/6 cups of almonds left
Step-by-step explanation:
Granola recipe = 2 1/3 cups of almonds
2 1/2 batches of granola = 2 1/3 cups of almonds × 2 1/2
= 2 1/3 × 2 1/2
= 7/3 × 5/2
= (7*5)/(3*2)
= 35/6
= 5 5/6 cups of almonds
A bag of almonds = 2 cups
5 bags of almonds = 10 cups
Cups of almonds left = 10 cups - 35/6 cups
= 60-35/6
= 25/6
= 4 1/6 cups

x = 6 is not a solution to the equation x + 13 = 18.
Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.
Is x = 6 a solution to the equation x + 13 = 18?Given the equation; x + 13 = 18.
We plug x = 6 into the equation
x + 13 = 18
6 + 13 ≠ 18
6 + 13 is not 18
x = 6 is not a solution to the equation x + 13 = 18.
Hence, Option C) No, because 6 + 13 = 18 is not true. is the correct answer.

The revenue from selling x tickets to a concert is the represented by the function r(x)=10x. The cost for buying tickets is represented by the function c(x) = 8x+40. The profit made from selling the tickets is represented by the function p(x) = r(x) - c(x). What is p(100)? *
Answers
Step-by-step explanation:
All these fancy terms is confusing. We just need to substitute the original equations into the final problem statement.
[tex]p(x) = 10x - (8x+40) = 10x - 8x - 40[/tex]
We can then substitute 100 for x and solve.
[tex]p(100) = 10(100) - 8(100) - 40[/tex]

Step-by-step explanation:
Dwight is selling flowers and candles for a school fundraiser. Flowers, x, sell for $7 for a bouquet, and candles, y, sell for $5. each. If he wants to sell at least $200 worth of flowers and candles, which inequality represents the situation where he sells x flowers and y candles?
A: 7x + 5y 200
C: 7x + 5y ≤ 200
D: 7x + 5y ≥ 200
Please explain why the right answer choice is correct. Thanks.
Answers
The Answer is D
Answer:
D: 7x + 5y ≥ 200
Step-by-step explanation:
If flowers sell for $7 and candles sell for $5, we can write those as 7x and 5y. Now, our inequality is 7x + 5y __. The words "at least" can translate to greater than or equal to. The symbol for that is ≥. Now, he wants to sell at least $200 worth of goods. That means we can write our inequality as 7x + 5y ≥ 200.

The parabola in the figure below has an equation of the form
y = ax^2 + bx - 4.
Find the equation of the parabola
Answers
Answer:
y = - x² + 5x - 4
Step-by-step explanation:
Given that the zeros are x = 1 and x = 4 , then the corresponding factors are
(x - 1) and (x - 4) , then
y = a(x - 1)(x - 4) ← a is a multiplier
= a(x² - 5x + 4)
To find a substitute the coordinates of any other point on the parabola into the equation.
Using (2, 2), then
2 = a(4 - 10 + 4) = - 2a ( divide both sides by - 2 )
a = - 1
Thus
y = - (x² - 5x + 4) = - x² + 5x - 4 ( with a = - 1 and b = 5 )
Find the total amount given the original price and tax rate. Round to the nearest cent if necessary.
$15.25,7%
Answers
Given:
Original price = $15.25
Tax rate = 7%
To find:
The total amount.
Solution:
We know that,
Total amount = Original price + Tax
According to the question,
Total amount = 15.25 + 7% of 15.25
[tex]\text{Total amount}=15.25+\dfrac{7}{100}\times 15.25[/tex]
[tex]\text{Total amount}=15.25+1.0675[/tex]
[tex]\text{Total amount}=16.3175[/tex]
Round to the nearest cent (two decimal places).
[tex]\text{Total amount}\approx 16.32[/tex]
Therefore, the total value is $16.32.
solve: x2 + 8x - 9 = 0
please i need it urgently
Answers
Answer:
x = 1 or x = -9
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 8 x - 9 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 9 to both sides:
x^2 + 8 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 16 to both sides:
x^2 + 8 x + 16 = 25
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x + 4)^2 = 25
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x + 4 = 5 or x + 4 = -5
Hint: | Look at the first equation: Solve for x.
Subtract 4 from both sides:
x = 1 or x + 4 = -5
Hint: | Look at the second equation: Solve for x.
Subtract 4 from both sides:
Answer: x = 1 or x = -9

Answers
Answer:
Step-by-step explanation:
we need that theta angle .. soooo.... use SOH CAH TOA to remind yourself how the trig functions fit on the triangle.....
since we have all 3 side any one of the above trig functions would work. as a side note.. Tan is limited to the 1st quadrant on a calculator.. so maybe Cos is a good choice. although it would work in this case....
sooo ....
Cos(Ф) = Adj / Hyp
Ф = arcCos( 24 /25)
Ф ≈16.26°
I don't have csc on my calculator but I know that 1/sin = csc sooo
csc(16.26)=1/sin(16.26) ≈ 3.57
sec(16.26)= 1/cos(26.26) ≈ 1.041
cot(16.26) = cos(16.26) / sin(16.26) ≈3.476
Answer:
csc(0)= 25/7
sec(0)= 25/24
cot(0)= 24/7
