Write an absolute value equation to represent the maximum and minimum weight for the bags of sand. b. Solve the equation and interpret the result.
From the situation described, we have that:
a. The absolute value equation is: |w - 35| = 8.
b. The solutions are w = 27 and w = 43, meaning that the minimum weight is of 27 pounds and the maximum weight is of 43 pounds.
What is the missing information?A home improvement store sells bags of sand, which are labeled as weighing 35 pounds. The equipment used to package the sand produces bags with a weight that is within 8 pounds of the labeled weight.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.
For this problem, the difference between the weight w and 35 pounds is of 8 pounds, hence the equation is:
|w - 35| = 8.
From the definition, the solutions are given as follows:
w - 35 = -8 -> w = 27.w - 35 = 8 -> w = 43.The solutions are w = 27 and w = 43, meaning that the minimum weight is of 27 pounds and the maximum weight is of 43 pounds.

According to the question, Adelaide is the employee and she has to select a reward from four gifts. And those are 6 coffee mugs, 7 DVDs, 10 CDs and 3 gift baskets.
Now, calculate the probability that the gift is either a coffee mug or CD.
Let us assume, ‘G’ represents the gift card, ‘C’ represents the coffee mug and ‘D’ represents the CD.
The total number of items are [tex]4+6+7+10+3 = 30[/tex] items
P(G or C or D) = P(G) + P(C) + P(D)

The measure of an inscribed angle is one-half the measure of the central angle.
What is the inscribed angle and the circumscribed angle?An inscribed angle in geometry is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle formed by two given points on a circle at a given point on the circle.
The measure of an inscribed angle is one-half the measure of the central angle. The measure of a circumscribed angle is 180 degrees minus the measure of the central angle.
Given: P lies outside
m ∠ABC = m ∠DBC – m ∠DBA ( Addition Postulate, Subtraction Property of Equality)
m ∠DBC = m 1/2(arc DC)
m ∠DBA = m 1/2(arc DA) (The measure of an inscribed ∠ whose side diameter is half the measure of the intercepted arc (Case 1)).
m ∠ABC = m 1/2 (arc DC) – m 1/2(arc DA) (Substitution)

Take has a square-shaped garage with 32 square meters of floor space. she plans to build an addition that will increase the floor space by 50%. what will be the length of one side of the new garage?
The length of one side of the new square-shaped garage is 4√3 meters.
A square is a two dimensional figure that has 4 equal sides. The area of a square can be solved by multiplying the length of its side by itself.
A = s^2
where s = side length
If the initial square-shaped garage has an area of 32 square meters and will be increased by 50%, then the new area should be 50% more than the initial area.
new floor area = 50% initial area + initial area
new floor area = 50%(32) + 32
new floor area = 16 + 32
new floor area = 48 square meters
If the new garage has a floor area of 48 square meters, using the formula for the area of a square, solve for the length of its side.
A = s^2

What is the mass of gasoline (density = 0.680 g/cm3 ) in a 94.6 l gasoline tank?
A 94.6 L gasoline with a density of 0.680 g/cm^3 has a mass of 64328 g.
Density is defined as the ratio between the mass of a substance and the volume it occupies. Denoted by ρ, density is mass per unit volume and the formula is given below:
ρ = mass / volume
Converting first the volume from L to cm^3.
1 L = 1000 cm^3
94.6 L = 94.6(1000 cm^3)
94.6 L = 94,600 cm^3
Given the density of the gasoline and its volume, solve for the mass of the gasoline using the formula for the density.
ρ = mass / volume
0.680 g/cm^3 = mass / 94,600 cm^3
mass = 0.680 g/cm^3 (94,600 cm^3)
mass = 64328 g

f(x) = f(x) + k
This is a translation transformation that shifts the original function f(x) either k units up or k units down. If k is more than 0 then k shifts up. If k is less than 0 then k shifts down.
Here, k = -5<0

Let h(x) be the reflection of f(x)=3 x+3 in the x -axis. What is a function rule for h(x) ?
The function rule for h(x) = -3x -3.
In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value. If it is reflected around the y-axis, it will stay the same, which gives h(x) = 3x + 3. Flipping around the x-axis (assuming y = 0) has the y-axis as the axis of symmetry, but it is concave down.
The function rule around the x-axis gives a complementary sign of the value of the function, so
h(x) =-3x-3 will be reflection of f(x) =3x+3

Let

be an arithmetic series.
Then, the nth term will follow the formula:
a(n) = a(1) + (n-1) . d
where d = the common difference.
The value of d is:
d = a(2) - a(1) = a(n) - a(n-1).
The series given is:
-5+2+9+16+ . . . . . . . +261+268
This is an arithmetic series with a(1) = -5 and
d = 2 - (-5) = 7
Substitute these parameters into the formula of the nth term:
a(n) = a(1) + (n-1) . d
a(n) = -5 + (n-1) . 7
a(n) = 7n - 12
Let a(n) = 268, then:

Katherine is very interested in cryogenics (the science of very low temperatures).
With the help of her science teacher she is doing an experiment on the affect of low
temperatures on bacteria. She cools one sample of bacteria to temperature of -51°C
and another to -76°C. What was the temperature difference in the two experiments?
Temperature difference of experiments is -25°C.
Step-by-step explanation:
Given that
Katherine is very interested in cryogenics (the science of very low temperatures).With the help of her science teacher she is doing an experiment on the affect of low temperatures on bacteria.She cools one sample of bacteria to temperature of -51°C and another to -76°C.To find
Temperature difference in the two experimentsSo, according to the question
we have,
Temperature of 1st experiment = -51°C, andTemperature of 2nd experiment = -76°CWe have to find Temperature difference of experiments
So, we can say that
Temperature difference of experiments
= Temperature of 2nd experiment - Temperature of 1st experiment
Now, putting the all given values,
We, will get
Temperature difference of experiments = -76 - (-51)
= -76+51
= -25°C,
Answer:
So, Temperature will fall 25°C,To learn more about Temperature difference, please click on the link:
