James buys 8 tomatoes that have a combined weight of 4.5 pounds. The scale measures to the nearest hundredth of a pound. What is the most precise value of the average weight of the tomatoes that James purchases, given the level of accuracy of the scale?
Answer:
Most precise value of the average weight is 0.56 pounds
Step-by-step explanation:
To get the precise value, we start by getting the average weight
That will be total weight/8
= 4.5 pounds/8 = 0.5625
we are told that the scale records to the nearest hundredth
So we need to express the obtained value in hundredths
That will be 0.56 pounds
If A = {1, 2, 3, 4, 5, 6}, B = {1, 2, 3, 5, 7, 9} and C = {3, 5, 6, 7, 8, 9}, What is the intersection of the set A and set C? {1, 2, 3, 4, 5, 6, 7, 8, 9} {1, 2, 3, 4, 5, 6, 7, 8, 9} {1, 2, 3, 4, 5, 6, 7, 9} {1, 2, 3, 4, 5, 6, 7, 9} {3, 5, 6} {3, 5, 6} {1, 2, 3, 5}
Answer:
[tex]A\,\cap\,C = \{3,5,6\}[/tex]
Step-by-step explanation:
From Set Theory we know that intersection is a binary operation between two sets consisting in labeling the common elements of both sets. If [tex]A=\{1,2,3,4,5,6\}[/tex] and [tex]C =\{3,5,6,7,8,9\}[/tex], then [tex]A\,\cap\,C = \{3,5,6\}[/tex].

What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of a line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
As per the information provided:
The points are collinear (i.e. they lie on a straight line), which means that the function is linear. We can find the equation of the line using the two-point form:
(y - 18)/(x - 10) = (30 - 18)/(18 - 10)
Simplifying this equation gives:
y - 18 = 3/2(x - 10)
y - 18 = 1.5x - 15
y = 1.5x + 3
So the function is linear, but not a direct variation function, and has a slope of 1.5.

The amount of water a washing machine uses varies directly with the number of loads it washes. If a washing machine uses 28 gallons for 2 loads of laundry, how many gallons would it use for 10 loads of laundry?
140 gallons of water would it use for 10 loads of laundry.
What is meant by the term direct proportional?A direct proportion is an arithmetical comparison of two numbers whose ratio is comparable to a constant value. According to the proportion definition, two ratios are in proportion when they are equivalent. The proportions are indicated by the symbol "∝".For the given question;
The amount of water a washing machine uses varies directly with the number of loads it washes.
Let amount of water be 'w'.
The number of loads be 'l'
w ∝ l
w = kl
k = proportionality constant.
For, w = 28 gallons
l = 2 loads of laundry
Put in the equation;
28 = 2 k
k = 14
Now, when l = 10 loads of laundry, w = ?
w = 14 × 10
w = 140
Thus, 140 gallons of water would it use for 10 loads of laundry.

Answer:
22 degrees
Step-by-step explanation:
The total degree of a triangle is 180 degrees.
we are given two degrees already; 90 degrees (from the right angle sign) and 68 degrees from the problem. If we create an equation to reflect this we can find the missing angle:
180 = 90 + 68 + x
180 = 158 + x
x = 22
Step-by-step explanation:
<TSU=68
<STU=90

What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
The data points given are:
(1,2.5), (2,4.2), (4.5,6), (6,7), (8,8.1), (10,11)
Note that the growth seems to be linear, therefore, find a linear equation for the data.
Use (1,2.5) and (2,4.2) to find the slope of the line:
m = (4.2-2.5)/(2-1)
m = 1.7
The equation of the line with slope m = 1.7 and passes through point (1, 2.5) is:
y - 2.5 = 1.7(x - 1)
y = 1.7x - 1.7 + 2.5
y = 1.7x + 0.8
Substitute x = 3 into the above equation:
y = 1.7(3) + 0.8
y = 5.9
Hence, the distance run on day 3 is about 5.9 miles.

what is the equation of the line perpendicular to y=1/2x-3 going through the point P(10,5)?
Answer:
y=-2x+25
Step-by-step explanation:
the slope has to be -2, becauze in perpendicular lines, the slopes are opposite.
put it into y-y1=m(x-x1) form, which is y-5=-2(x-10)
then get rid of the parenthesis by distribution, which gives you y-5=-2x+20 (-10x-2 gives a positive 20)
then isolate y and balance the equation.
y-5+5=-2x+20+5, which gives you
y=-2x+25

how are the particles in a solid piece of ice organized
Answer:
The particles in most solids are closely packed together and do not move around. ... Ice is different from most solids because its molecules are not packed as closely together as they are in liquid water. This means ice takes up a little more space than the same amount of liquid water. This is why ice floats.

Zoey made 9 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4-cup servings. Thirteen people are going on the camping trip. Can Zoey make enough 3/4-cup servings so that each person on the trip has one serving?
Answer:
Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.
Step-by-step explanation:
Zoey made 9 1/2 cups of trail mix for a camping trip.
She wants to divide the trail mix into 3/4-cup servings.
Thirteen people are going on the camping trip.
This means :
1 person = 3/4 cup servings
13 people = x
Cross Multiply
13× 3/4
= 39/4
= 9 3/4 cup
So for Zoey to be able to serve 13 people the trail mix in 3/4 cup servings, she need 9 3/4 cups of the trail mix
From the she made 9 1/2 cups of the trail mix.
Hence, Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.
