Answer: The largest angle is 7x
Step-by-step explanation:
Their sum is 180, so
3x + 5x + 7x = 180
5x = 180 --> x = 12
The largest angle is 7x, which is 7(12) = 84
For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric
temperature can be described by the formula t = -0.0035a +g, in which t is the atmospheric
temperature in degrees Fahrenheit, a is the altitude, in feet, at which the atmospheric temperature is
measured, and g is the ground temperature in degrees Fahrenheit. Solve the equation for a. If the
atmospheric temperature is -17.4°F and the ground temperature is 40 °F, what is the altitude?
The equation for a is a =
If the atmospheric temperature is -17.4 °F and the ground temperature is 40 °F, then
a= feet.
Answer:
a=16400 feet
Step-by-step explanation:
t = -0.0035 a +g
-17.40 = -0.0035 a+40
-17.40-40=-0.0035a+40-40
-57.40=-0.0035a
a = -57.40/-0.0035
a=16400 feet

Which of the following functions describes the sequence 4, –2, 1, –12, 14, . . .? A. f(1) = 4, f(n + 1) = –2f(n) for n ≥ 1 B. f(1) = 4, f(n + 1) = f(n) – 2 for n ≥ 1 C. f(1) = 4, f(n) = 12f(n + 1) for n > 1 D. f(1) = 4, f(n) = –12f(n – 1) for n > 1
Answer: D. [tex] f(1) = 4,\ \ f(n+1)=\dfrac{-1}{2}f(n) [/tex]
Step-by-step explanation:
The given sequence: [tex]4, -2,1,\dfrac{-1}{2},\dfrac14,....[/tex]
Here, first term: [tex]f(1)=4[/tex]
Second term: [tex]f(2)=-2[/tex]
Third term : [tex]f(3)=\dfrac{-1}{2}[/tex]
It can be observed that it is neither increasing nor decreasing sequence but having the common ratio.
Common ratio: [tex]r=\dfrac{f(2)}{f(1)}=\dfrac{-2}{4}=\dfrac{-1}{2}[/tex]
So, [tex]f(n+1)=\dfrac{-1}{2}f(n)[/tex] [as in G.P. nth term= [tex]a_{n+1}=ar^n[/tex]]
Hence, correct option is D. [tex] f(1) = 4,\ \ f(n+1)=\dfrac{-1}{2}f(n) [/tex]
If the marked price of an article is Rs. x, discount amount is
Rs. y and the VAT amount is Rs. 2, Calculate the selling
price of the article including VAT.
Answer:
Rs. (x - y + 2)
Step-by-step explanation:
The marked price is the price that a product is to be sold. The product can be sold at a discount which is below the marked price of the product.
The marked price of the article is Rs. X. The discount is Rs. y, therefore the article price = marked price - discount = x - y.
But since the article is sold with a VAT of Rs. 2, the VAT is added to the price, therefore the selling price of the article including VAT is Rs. (x - y + 2)

The San Andreas fault separates the pacific plates from the North America plate. The pacific plate moved northward relative to the North American plate at a rate of 5.7 cm/year. Currently LA and San Francisco are about 470km away from each other, how long will it take for LA and SF to be next to each other? Answer in years
Answer:
8.2 million years
Step-by-step explanation:
The time can be found from ...
time = distance/speed
time = (47.0×10^4 m)/(5.7×10^-2 m/yr) = 8.2×10^6 yr
It will take about 8.2 million years for LA to have the same latitude as SF.

3/2x+1 = 13
find x.
What is x?
Answer:
8
Step-by-step explanation:
Please write this as (3/2)x + 1 = 13.
Start the process of solving for x by subtracting 1 from both sides:
(3/2)x = 12
Eliminate the fractional coefficient by multiplying both sides by 2/3:
(2/3)(3/2)x = (2/3)(12), or
x = 8
10. While at the beach, Daniel buys lunch for
his family from a food stand. He purchases
one hot dog for $2.50 and 3 hamburgers. If he
spent $ 13 total, write and solve an equation to
find h, the amount each hamburger cost.
Answer: Each hamburger cost $3.50
Step-by-step explanation:
He spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equation,
2.50 + 3h = 13 Now solve for x
-2.50 2.50
3h = 10.50
h = 3.50
Check:
2.50 + 3(3.50) = 13
2.50 + 10.50 = 13
13= 13

In a city, the record monthly high temperature for March is 56 degrees Fahrenheit. The record monthly low temperature is -4 degrees Fahrenheit. What Is the range of temperature for March?
Answer:
60 degrees.
Step-by-step explanation:
In mathematics, a "range" is described as the difference between the lowest and highest numbers in a data set. To find the range, we must subtract. (This is what the word "difference" indicates in math)
56 - (-4) =
56 + 4 = 60 (the negative signs cancel out)
Thus, the range of temperature for March is 60 degrees :) Hope this helped!
God bless and stay safe.
Which function is not defined at 0? Please help urgent
Answer:
b and g
Step-by-step explanation:
a. is y = 0³ = 0
b. is y = ln(0), which is undefined because ln(x) is only defined for x > 0
c. is y = 1 / (1 + e^-0) = 1 / (1 + 1) = 1/2
d. is y = 0
e. is y = 0² = 0
f. is y = sin(0) = 0
g. is y = 1/0, which is undefined because division by 0 is undefined
h. is y = e^0 = 1
i. is y = |0| = 0
j. is y = √0 = 0
Someone help me solve this expression please
Step-by-step explanation:
To solve, we have to remember PEMDAS (Parenthesis, Exponent, Multiply / Divide, Add or Subtract).
Here, the curly brackets act as parenthesis, so we solve that first.
• 3 + 7 = 10
Then, we multiply by 4.
• 10 • 4 = 40
Finally, we add 6 to 40.
• 40 + 6 = 46.
Our final answer: 46
Answer:
46
Step-by-step explanation:
We are asked to evaluate the expression. Remember to solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
[tex]6+4 * (3+7)[/tex]
Solve inside the parentheses. Add 3 and 7.
⇒3+7=10
[tex]6+4*(10)[/tex]
Multiply 4 and 10.
⇒4*10=40
[tex]6+40[/tex]
Add 6 and 40.
⇒6+40=46
[tex]46[/tex]
When the expression 6+4*(3+7) is evaluated, the result is 46.

Problem Solving
D A farmer watered 10/82 of a field. What decimal is
equivalent to the fraction of the field the farmer
watered?
type here
Answer:
0.1219512195122
Step-by-step explanation:
To write 10/82 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 10 by 82 what we write down as 10/82 and we get 0.1219512195122
The line $x = 4$ is an axis of symmetry of the graph of $y = ax^2 + bx + c.$ Find $\frac{b}{a}$.
Answer: b/a = -8
Step-by-step explanation:
When we have a quadratic equation:
y = a*x^2 + b*x + c.
The vertex of this function (and the axis of symetry) is located at:
x = -b/2a
Now, we know that the axis of symmetry is at x = 4.
then we have:
4 = -b/2a
And we want to find b/a.
Then we start with:
-b/2a = 4.
first we multiply by 2 in each side:
2*(-b/2a) = -b/a = 2*4 = 8.
now we multiply by -1 in each side:
-1*(-b/a) = b/a = -1*8.
Then we have: b/a = -8
If you had 6 million dollar and you divided that by 1 billion what would you get. Then once you find that multiply your answer by 10. What do you get.
Answer: You get 0.06 which is 6 cents in terms of money.
Step-by-step explanation:
6 millions could be written as 6,000,000 and 1 billion could also be written as 1,000,000,000 so using this set up a fraction to divide it.
[tex]\frac{6000000}{1,000,000,000}[/tex] = 0.006
0.006 * 10 = 0.06
Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three the distance from point P to point R
Answer:
7/3
Step-by-step explanation:
The distances have the ratio ...
(Q -P) = (2/3)(R -P)
Q = P +(2/3)R -(2/3)P = (2R +P)/3
Qy = (2Ry +Py)/3 = (2·0 +7)/3 = 7/3
