postcard costs $0.25 including tax.
Part A
How can Doug use place-value blocks to
find the total cost of the postcards? What is
the total cost?
The total cost is $1.75
What is Place value?The foundation of our entire number system is place value. In this approach, the value of a digit in a number is determined by where it appears in the number. The digits in the numbers 42,316 and 61,432 are distinct from one another.Given that we've done it:
7 postcards were purchased by Doug's family.Each postcard costs $0.25 after tax.The total price is shown by:
7 x 0.25 = $1.75Now, let's display the following in a number line:
Put all the numbers with a difference of 0.25 on the number line, run it seven times, and the result will appear.There are 7 hops between each step of 0.25 duration to get to the needed answer.So, after seven hops, we arrive at 1.75, which is the correct response.
Hence, the total cost is $1.75

Different liquids freeze at different temperatures, called their freezing points. Liquid acetone, used in nail polish remover, has a freezing point of – 137°F. Water has a freezing point of 32°F. How much warmer is the freezing point of water than the freezing point of acetone? °F
The freezing point of water in relation to the freezing point of acetone, is 169 °F
How to find the difference in freezing points?The difference between the freezing point of water (how much warmer the freezing point of water is) and the freezing point of acetone can be found by the formula:
= Freezing point of water - Freezing point of acetone
Freezing point of water = 32°F
Freezing point of Acetone = – 137°F
In relation to the freezing point of acetone, the degrees warmer that the freezing point of water is:
= 32 - (- 137)
= 32 + 137

Here we have to prove that one angle and two sides of the triangle ABW is equal to the one angle and two sides of the triangle DCW
Consider the triangle ADW,
In the triangle ADW the length of the WA is equal to the length of WD.
Therefore the measure of angle A is equal to the measure of angle D.
So in triangle ABW and the triangle DCW, one side and two angles are equal.

Use the z-distribution table on pages A-1 and A-2 or technology to solve. Suppose a set of data is normally distributed. Below which z-score do approximately 34 of the data lie?
The z-score under which 3/4 of the data lies is of:
Z = 0.675.
Normal Probability DistributionThe z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The z-score under which 75% of the distribution lies is the 75th percentile, hence it is the value of Z with a p-value of 0.75.
Looking at the z-table, this value is of 0.675, as 0.675 is the mean of the p-values of Z = 0.67 and Z = 0.68.

The image of the corresponding to each slope is attached
What is slope?A line's steepness can be determined by looking at its slope.
Slope is determined mathematically as "rise over run" (change in y divided change in x).
assuming slope is m
m = (y₂ - y₁) / (x₂ - x₁) = change in y / change in x
considering the formula
slope is between 0 and 1 when rise (change in y) is so smaller than run (change in x) hence the line is closer to horizontal
slope is greater than 1 then the rise is more than run, in this case the line is approaching vertical line
numbers less than zero are negative hence slope has a negative value
A horizontal line is a line that has a slope of of zero while vertical lines has its slope as infinity

Which equation is the inverse of y = 100-x²?
Oy=± √100-x
O y=10± √√x
Oy=100+√x
Oy=+√x-100
Answer:
y = ±√100-x
Step-by-step explanation:
To work out the inverse of this function :
We solve for x then swap x and y :
Solving for x :
y = 100 - x²
Add x² to both sides :
x² + y = 100
Subtract y from both sides :
x² = 100-y
Square root both sides :
x = ±√100-y
Now we have solved for x. Now swap x and y :
y = ±√100-x
This is our final answer and is the first option.

Which expression uses the commutative property of addition and the associative property of
multiplication to rewrite the expression 3 (28) +7?
O 7+(3-2).8
O 3 (8-2)+7
O 7+3 (16)
O (3-2) 8+7
The expression that uses the commutative property of addition and the associative property of multiplication to rewrite the expression 3 (28) +7 is 7+(3-2).8
The commutative property of addition states that a change in the order of the numbers being added does not affect the sum. We can define commutative property of addition as adding the numbers in any order will give the same answer.
a + b = b + a
3(2x8) + 7 = 7 + 3(2x8)
The associative property of multiplication says that while multiplying three numbers, regardless of the way the numbers are grouped, the end result will always be the same.
a(b x c) = (a x b) c
7 + 3(2x8) = 7 + (3.2)8
Therefore, the expression that uses the commutative property of addition and the associative property of multiplication to rewrite the expression 3 (28) +7 is 7+(3-2).8

same number of new stamps each week to add to his
collection. The equation shown below can be used to
determine the number of stamps (y) in Paul's stamp
collection x weeks after he inherited the stamps.
y = 3x + 40
Based on the equation, which statement is true?
A) The stamp collection had 3 stamps in it when Paul inherited it.
B) So far, Paul has purchased 40 additional stamps for the collection.
C) Since inheriting the collection, Paul has bought 3 new stamps each week.
D) Six weeks after he inherited the collection, Paul's stamp collection contains 18 stamps
Based on the equation y = 3x+40 where y is the number of stamps and x is number of weeks after Paul inherited the stamps, the correct statement is since inheriting the collection, Paul has bought 3 new stamps each week.
According to the question,
We have the following information:
y = 3x+40 where y is the number of stamps and x is number of weeks after Paul inherited the stamps
Now, when we observe this equation carefully, we notice that 3x is added to 40. So, it means that 40 is constant. Then, the number of stamps increasing per week is in the multiplication of 3. Or, in other words, 3 new stamps are bought each week.
For 1st week:
y = 3*1+40
y = 43
For 2nd week:
y = 3*2+40
y = 6+40
y =46
Hence, the correct option is C.
