In ΔUVW, u = 44 inches, ∠W=56° and ∠U=117°. Find the length of v, to the nearest inch.
Answers
Answer:
The length of v is 6 inches
Step-by-step explanation:
Here, we want to calculate the length of v to the nearest inch
The best way to go about this is to use the sine rule
But before we proceed, we need the measure of angle V
Mathematically, since we have a triangle
W + U + V = 180
This is the sum of angles in a triangle
56 + 117 + V = 180
V = 180-56-117
V = 7 degrees
so we proceed to use sine rule to get the length of v
Mathematically;
v/Sin V = u/Sin U
Thus;
v/sin 7 = 44/sin 117
v = 44sin 7/sin 117
v = 6.018
This is approximately 6 inches

Find the circumference and the area of a circle with radius 7ft .
Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.
Answers
Answer:
C=43.96 ft.
A=153.86 ft.^2
Step-by-step explanation:
for circumference, use C=2πr
for area, use A=π[tex]r^{2}[/tex]
The circumference and the area of a circle with radius 7 feet are 43.96 feet and 153.86 square feet, respectively.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
And the general formula of the circle,
(x – h)²+ (y - k)² = r²,
where (h, k) is the center and r is the radius of the circle.
Given:
A circle with radius 7 feet.
Then the circumference of the circle,
= 2πr
= 2(3.14)(7)
= 43.96 feet.
The area of the circle,
= πr²
= (3.14) (49)
= 153.86 square feet.
Therefore, circumference is 43.96 feet and area is 153.86 square feet.

Find the coordinates of the point where y-4x=1 crosses the y axis
Answers
Answer:
(a) (-1/4,0)
(b) k = (10-c)/2
Step-by-step explanation:
(a) A point passing through the y-axis is the same as finding the y-intercept.
[Move terms to right-hand side; y = mx + b form]
y = 4x + 1
[Find x, when y = 0]
0 = 4x + 1
-1 = 4x
-1/4 = x
At x = -1/4, y = 0 therefore the point: (-1/4,0) crosses the y-axis.
(b) To find the value of k in (k,10), we need to find x. Given y= 10 x=k c=constant
[Find x by plugging in known values]
Using y = 2x + c,
10 = 2k + c
10 - c = 2k
(10-c)/2 = k

Emma is 10 years old. she asked her father how old he is. her father answered, "when you are my age I will be 70." how old is Emma's father.
Answers
Answer:
40
Step-by-step explanation:
Emma age: yE = 10 + x (x is timeline)
Father age: yF = A + x (x is timeline, A is Father age today)
in time x1: Emma will be A years old, and Father will be 70 years old.
yE (x1) = 10 + x1 = A
yF (x1) = A + x1 = 70
System of equations with unknown values: x1 and A.
substract equation 1 - equation 2:
10 - A = A - 70 ⇒ 80 = 2A ⇒ A = 40
So, father is 40 years old now
Emma's father is 40 years old
Let the age of Emma father be y
Age of emma = 10 years
In x years time;
Emma age will be 10 + xFathers age will be y + xIf in x1 years time, Emma will be y years old and his father will be 70 years old
Emma age: yE = 10 + x (x is timeline)
Emma's current age will be 10 + x = yHis father;s current age will be y + x = 70
Solving both equations simultaneously;
10 - y = y - 70
10+70 = y + y
80 = 2y
2y = 80
y = 80/2
y = 40 years
Hence Emma's father is 40 years old

A dietician gathered data about the amounts of flour, baking powder, and butter used for several different muffin recipes. She used a graphing tool to organize the data in different scatter plots and found the following lines of best fit:
The relationship between the baking powder used, x, and the flour used, y, is modeled by the equation y = 0.13x + 0.92, and the correlation coefficient for the data is 0.953.
The relationship between the baking powder used, x, and the butter used, y, is modeled by the equation y = 0.24x + 0.76, and the correlation coefficient for the data is 0.802.
The relationship between the flour used, x, and the butter used, y, is modeled by the equation y = 0.86x + 0.52, and the correlation coefficient for the data is 0.693. Which line of best fit can the dietician expect to produce the most reliable predictions?
A. the line modeling the baking powder and the butter used
B. the line modeling the baking powder and the flour used
C. the line modeling the flour and the butter used
D. All three lines will give equally reliable predictions.

Step-by-step explanation:
plato master test
On comparing the pairwise R - squared value between the three variables, we find that the line modeling the baking powder and the flour used can be expected to produce the most reliable predictions.
What is R - squared value ?R-Squared value is a quantifiable analysis of how well the line of best fit (linear regression model) fits your data. A value closer to 1 (100%) is usually good.
The coefficient of determination - R - squared value is square of the correlation coefficient.
R - squared value of the relationship between baking powder and flour used = 0.953² = 0.908
R - squared value of the relationship between baking powder and butter used = 0.802² = 0.643
R - squared value of the relationship between flour and butter used = 0.693² = 0.48
Since, on comparing the R - squared values of the three relationships, we find that the R - squared value of the relationship between baking powder and flour used is largest. Thus, line of best fit between baking powder and flour is expected to produce the most reliable predictions.

No, you will not be able to buy 3 more CDs. Question 3 c. Explain your reasoning for part (b). Each CD costs $ at the regular price, so 3 CDs would cost $ .
Answers
Answer:
$7.6 ;
No, you will not be able to buy 3 more CDs
$9.5
$28.5
Step-by-step explanation:
Given that :
Cost of 4 CDs = $30.40
Cost per CD is equal
Sale price = 80% of original price
Price p per CD:
Cost of 4 CDs / number of CDs
$30.40 / 4
= $7.6
2)
No, you will not be able to buy 3 more CDs
If x = original price
80% of x = 7.6
0.8x = 7.6
x = 7.6 / 0.8
x = $9.5
$9.5 * 3 =$28. 5
Hence, $25 can't buy 3 CDs the next day (28.5 > $25)
