The average change in temperature per hour is 7.1°.

Given, the temperature in a certain city changed to 34.084°F

over 4.8 hours.

the average change in temperature per hour = ?

average temperature = change in temperature/time taken.

= 34.08/4.8

= 71/10

= 7.1°f

the change in temperature is 7.1°f

Hence the change in temperature per hour is 7.1°f.

Answer:

Incomplete question

...

The measure of FG is 16 units.

The measure of FG can be found as follows:

GE is an angle bisector.

An angle bisector is a bisector that bisect angles into two equal halves.

Therefore,

GE bisect ∠FEH

Hence,

FG = GH

FG = x + 11

GH = 3x + 1

x + 11 = 3x + 1

11 - 1 = 3x - x

10 = 2x

x = 10 / 2

x = 5

Therefore,

FG = x + 11 = 5 + 11 = 16 units

Answer: 104.3

Step-by-step explanation: To divide a decimal by another decimal: Move the decimal point in the divisor to the right until it is a whole number.

The function is increasing over the interval (-3,-1).

A table with x and f(x) values are given as:

x         f(x)

-6         34

-5          3

-4        -10

-3         -11

-2         -6

-1           -1

0           -2

1            -15

We have to check whether this function is increasing or not in the intervals  (–6, –3), (–3, –1), (–3, 0), (–6, –5).

A function is said to be increasing over an interval (x, y), if for x < y, it follows that f(x) < f(y).

Consider the intervals one-by-one.

For (-6, -3), we have the function values in between which are  34 > 3 > -10 > -11. So in this interval the function is not increasing but decreasing over the x-values in (-6, -3).

For (-3, -1), the corresponding function values are -11 < -6 < -1. Here the function values are increasing over the x-values in the interval (-3, -1).

For (-3,0), the corresponding function values are -11 < -6 < -1 >-2. Since we got -1 > -2 in the interval (-3,0), the function is not increasing here also.

For (-6,-5), the corresponding function values are 34 > 3. So the function is not increasing but decreasing.

The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run" (change in y divided by change in x).

slope of the line  = -5/4.

The line pass through the points (-3, 2) and (1, -3)

The formula for finding slope from two points (x₁, y₁) and (x₂, y₂) on a line is m = (y₂ - y₁) / (x₂ - x₁). Here, m = slope of the line

m = -3-2/1 +3 = -5/ 4

Step-by-step explanation:

The volume of the spherical rubber ball to the nearest cubic inch is 87.11 cubic inches.

The capacity of a sphere is its volume. It is the area that the sphere occupies. Cubic measurements for sphere volume include m^3, cm^3, and in^3.

The formula of volume of the sphere is

V = 4/3πr3

given that the radius of spherical rubber ball is 2 3/4

here the radius is given in improper fraction

now convert it into the decimal by following procedure.

first multiply the 2 with 4

2 X 4 = 8

now add 8 to 3. 8 + 3 = 11

The proper fraction of 2 3/4 is 11/4.

so, the decimal number is 2.75

now put r = 2.75 in formula to get the volume.

V = 4/3 X 3.14 X 2.75 X 2.75 X 2.75

V = 1.33333 X 3.15 X 20.7968

V = 87.11 cubic inches

Hence,the volume of the spherical rubber ball to the nearest cubic inch is 87.11 cubic inches.

The probability that a cookie is randomly picked and it does not contain chocolate or nuts will be 0.52

As per the question statement, a box of assorted cookies has 36% of them containing chocolate and 12% containing nuts, and of those, again 8% contain both chocolate and nuts, and we are assuming that the rest of the cookies neither contain chocolate, nor nuts.

Based on the conditions and our assumptions provided in the above mentioned statement, we are required to calculate the probability that a cookie is randomly picked and it does not contain chocolate or nuts.

Considering the total number of cookies in the box to be 100%, since 36% of them containing chocolate and 12% containing nuts and the rest of the cookies are assumed to contain neither chocolate, nor nuts,

The probability that a cookie is randomly picked and it does not contain chocolate or nuts will be [{100 - (36 + 12)}/100]

                                      = [(100 - 48)/100]

                                      = (52/100)

                                      = 0.52

An item is regularly priced at $78. Martina bought it at a discount of 80% off the regular price. Martina paid $15.6

Sales price:  The price that is paid by the buyer at the time when something is sold: People who sold their homes through real estate agents typically did not get a higher sale price than people who sold their homes themselves

The formula for calculating sales price of an item is:

s=p-(p x d)

where,

s is the sales price (which we are going to calculate in this problem)

p is the regular price of the item which is $78

d is the discount rate which is 80%

which means out of 100 = 80/100

substitute the above values in the formula then we get

s=$78-($78 x 80/100)

s=$78-($6240/100)

s=$78-$62.4

s=$15.6

Martina paid $15.6

Step-by-step explanation:

PEMDAS

The PEMDAS rule is an acronym representing the order of operations in math:

Given expression:

72 - 9 ÷ 3 · 2 + 2

Following the order of operations, carry out the multiplication and division first, working from left to right.

Divide 9 by 3:

⇒ 72 - 9 ÷ 3 · 2 + 2

⇒ 72 - 3 · 2 + 2

Multiply 3 by 2:

⇒ 72 - 3 · 2 + 2

⇒ 72 - 6 + 2

Now carry out the addition and subtraction, working from left to right.

Subtract 6 from 72:

⇒ 72 - 6 + 2

⇒ 66 + 2

Add 66 and 2:

⇒ 66 + 2

⇒ 68

72 - 9 ÷ 3 · 2 + 2 = 68

The factorization of the quadratic expression 25x² - 4 gives us (5x + 2)(5x - 2) where; x = -2/5 or 2/5

We are given the quadratic equation as;

25x² - 4

Now, this quadratic equation can be written as;

25x² + 10x - 10x  - 4

We can group this using algebra properties to get;

(25x² + 10x) - (10x + 4)

Collecting like terms gives us;

5x(5x + 2) - 2(5x + 2)

Thus, the factorization is;

(5x + 2)(5x - 2)

The values of x will be;

5x + 2 = 0

x = -2/5

It is listed below whether area or circumference needs to be calculated.

What is circumference?

The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were expanded out and straightened out to a line segment, the circumference would be the length of the arc. The curve length around any closed figure is more often referred to as the perimeter. The term "circumference" can also refer to the circle's actual location, which corresponds to a disk's edge. A sphere's circumference is equal to the length of any one of its great circles. The distance around a circle is its circumference, however this cannot be used as a definition if, as in many introductory presentations, distance is defined in terms of straight lines.
