Answer:
A. 12
Step-by-step explanation:
TU and CV are two chords of the circle that intersects at point w.
Thus,
[tex] x*3 = 9*4 [/tex] (two intersecting chords theorem)
Solve for x
[tex] 3x = 36 [/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{36}{3} [/tex]
[tex] x = 12 [/tex]

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
Answers
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
what is half the sum of x and y decreased by one-third y as a algebraic expression
Answers
Answer:
1/2(x+y) - 1/3
Step-by-step explanation:
I think this may be the answer based on the info you've given
Answer:
[tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex]
Step-by-step explanation:
We can translate these words into an expression by just reading them and interpreting them.
Half the sum of x and y.
We know that it's going to include [tex](x+y)[/tex], and if we're taking half of that, we multiply that by [tex]\frac{1}{2}[/tex], so [tex]\frac{1}{2}(x+y)[/tex]
We also know that one third of y will be multiplying y by [tex]\frac{1}{3}[/tex], so [tex]\frac{1}{3}y[/tex].
Since we are decreasing [tex]\frac{1}{2}(x+y)[/tex] by [tex]\frac{1}{3}y[/tex], there's a minus sign between the terms.
So, [tex]\frac{1}{2}(x+y) - \frac{1}{3}y[/tex].
Hope this helped!

45% of the pizzas in the freezer in the store are cheese pizzas. There are 120 pizzas in the
freezer. How many of them are cheese pizzas?
Answers
Answer:
54 cheese pizzas
Step-by-step explanation:
We know that there are 120 pizzas in the freezer, and 45% of them are cheese pizzas.
We want to find out how many cheese pizzas are in the freezer, so we should multiply 45% and 120.
45% * 120
Convert 45 % to a decimal. Divide 45 by 100 or move the decimal place 2 spots to the left.
45/100= 0.45 or 45.0 --> 4.5 ---> 0.45
0.45 * 120
Multiply 0.45 and 120
54
54 cheese pizzas are in the freezer.
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.
Answers
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)

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.
Answers
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

Step-by-step explanation:
To evaluate the expression, follow the rule of PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
[tex]20 \div (5-3) +5^2(3)[/tex]
Solve inside the parentheses first by subtracting 3 from 5.
5-3 = 2
[tex]20 \div (2) +5^2(3)[/tex]
Next, evaluate the exponent.
5² = 5*5= 25
[tex]20 \div 2+25(3)[/tex]
Next, multiply 25 and 3.
25 *3 =75
[tex]20 \div 2+75[/tex]
Then, divide 20 by 2.
20/2=10
[tex]10+75[/tex]
Finally, add 10 and 75.

The expression [tex]20 \div (5-3) +5^2(3)[/tex] evaluated is 85.

Answers
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]

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?
Answers
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!

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

The line $x = 4$ is an axis of symmetry of the graph of $y = ax^2 + bx + c.$ Find $\frac{b}{a}$.
Answers
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
