The percentage increase is 21.4% increase
Given Data
Initial temperature = 12 1/4°F = 49/4 = 12.25°F
Final Temperature = 15 3/5°F = 78/5 = 15.6°F
We know that the expression for percentage increase is given as
Percent Increase = Increase/Final *100
Percent Increase = 15.6-12.25/15.6 *100
Percent Increase = 3.35/15.6 *100
Percent Increase = 0.214 *100
Percent Increase = 21.4%
Hence there is a 21.4% increase

Please help my homework I still struggle
Answer:
[tex]x[/tex] = 12
Step-by-step explanation:
The shape ABCDEF is an irregular polygon.
The sum of the interior angles of any regular or irregular polygon = (n - 2) x 180 (where n is the number of sides of the polygon).
Therefore, the sum of the interior angles of shape ABCDEF = (6 - 2) x 180 = 720°
So to find the value of [tex]x[/tex], we need to add together all the interior angles and equal it to 720, then solve for [tex]x[/tex].
Before we do that, we need to determine angle F.
From inspection, we can see that angle F and 52° are a linear pair. We know that a linear pair of angles add up to 180°, so F + 52 = 180 ⇒ F = 180 - 52 = 128°
Therefore:
A + B + C + D + E + F = 720
(10[tex]x[/tex] - 5) + 108 + (8[tex]x[/tex] - 3) + (14[tex]x[/tex] - 25) + 133 + 128 = 720
Collect like terms:
10[tex]x[/tex] + 8[tex]x[/tex] + 14[tex]x[/tex] - 5 + 108 - 3 - 25 + 133 + 128 = 720
Combine like terms:
32[tex]x[/tex] + 336 = 720
Subtract 336 from both sides:
32[tex]x[/tex] = 384
Divide both sides by 32:
[tex]x[/tex] = 12

The circumference of a circle is
9.42 cm. Determine the radius(r)
given the equation for
circumference is, C =2??r
Answer:
1.5 cm
Step-by-step explanation:
1. To find the radius, we use the equation [tex]r = \frac{C}{2\pi}[/tex]
2. Now, we plug in the values and simplify to get the radius. In this case, we'll use pi as 3.14.
[tex]r = \frac{9.42}{2*3.14}[/tex] [tex]r = \frac{9.42}{6.28}[/tex] [tex]r = 1.5[/tex]Therefore, the radius is 1.5 cm.

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
A parallelogram is shown in figure with two diagonals.
We know that;
In a parallelogram, both diagonal intersect at midpoint of each diagonal,
So, We can formulate;
⇒ 2z + 7 = z + 9
Solve for z as;
⇒ 2z - z = 9 - 7
⇒ z = 2
And,
⇒ 3y - 5 = y + 5
⇒ 3y - y = 5 + 5
⇒ 2y = 10
⇒ y = 5
Thus, The value of z = 2
The value of y = 5

A case of juice holds 108 cans. How many six-packs of
juice does the case hold?
Answer:
18
Step-by-step explanation:
One case = 108 cans
One six-pack of juice = 6 cans
Therefore, to calculate how many six-packs of juice the case can hold, divide the capacity of the case (108 cans) by the number of cans in a six-pack (6):
108 ÷ 6 = 18
Therefore, a case will hold 108 individual cans or 18 six-packs

What is the area of the blue shaded figure if A=3 cm and B=5 cm?
Use 3.14 to approximate π.
The area of the blue shaded figure will be 47.9 cm².
What is Circle?
Circle is a two dimensional figure in which the set of all the points is equidistance from the center.
Given that;
In the figure,
A = 3 cm
B = 5 cm
Since, The area of a circle = πr²
So, For radius of small circle with radius 3 cm,
Area = πr²
Area = 3.14 × 3²
Area = 3.14 × 9
Area = 30.6 cm²
Hence, Area of small circle = 30.6 cm²
And, Area of the big circle with radius 5 cm,
Area = πr²
Area = 3.14 × 5²
Area = 3.14 × 25
Area = 78.5 cm²
Hence, Area of big circle with radius 5 cm = 78.5 cm²
So, The area of blue shaded circle = 78.5 - 30.6
= 47.9 cm²
Thus, The area of the blue shaded figure will be 47.9 cm².
