The total of 24 and a number x as an algebraic phrase
Answer:
24+x
Step-by-step explanation:
We need to find the expression for the following phrase i.e. the total of 24 and a number x.
Total means we need to add two numbers.
i.e.
Expression = 24+x
Hence, this is the required solution.

Write an equation in standard form of the line that passes through the point (9, 2) with a slope of 1/3
Answer:
y=1/3x-1
Step-by-step explanation:
You want to find the equation for a line that passes through the point (9,2) and has a slope of 1/3.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 1/3. So you can right away fill in the equation for a line somewhat to read:
y=1/3x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(9,2). When x of the line is 9, y of the line must be 2.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (9,2).
So, why not plug in for x the number 9 and for y the number 2? This will allow us to solve for b for the particular line that passes through the point you gave!.
(9,2). y=mx+b or 2=1/3 × 9+b, or solving for b: b=2-(1/3)(9). b=-1.
The equation of the line that passes through the point (9,2) with a slope of 1/3
is
y=1/3x-1
what is the measure of angle 8?
9514 1404 393
Answer:
135°
Step-by-step explanation:
Angle 8 and the one marked 45° are a linear pair, so are supplementary.
angle 8 = 180° -45°
angle 8 = 135°

The Heat (H) required to melt copper is proportional to the copper’s mass in grams (g). Suppose the number of calories to melt 1 gram of copper is represented by c . Which statements are true for this situation
Answer:
H = cg The number of calories to melt one gram is the constant of proportionality. Heat = calories(mass) Write as y = kx, where k is the constant of proportionality → H = cg → c is the constant of proportionality
Step-by-step explanation:
Write the linear inequality shown in the graph. The gray area represents the shaded region. y ≤ –x + 4 y ≤ –x – 4 y ≥ –x – 4 y ≥ –x + 4
For Example:
Write the linear inequality shown in the graph. The gray area represents the shaded region.
A. y ≤ 3x + 4
B. y ≤ 3x – 4
C. y ≥ 3x + 4
D. y ≥ 3x – 4
Answer: C
Step-by-step explanation:
1. The graph indicates that the line intersect the y-axis at -4.
2. Then, you must choose any point that are located within the region and replace them to see if the inequality is satisfied. Therefore, you have:
Point (0,2)

A camp needs 100 students to help with 4-year-old campers. Eight students from 4 different classes have agreed to help. How many more students are there needed?
Answer:
64
Step-by-step explanation:
Determine whether each of these sets is countable or uncountable. For those that are countably in nite, exhibit a one-to-one correspondence between the set of positive integers and that set. (a) integers not divisible by 3. (b) the real numbers with decimal representations consisting of all 1s.
Answer:
a) Countably Infinite
b) Countably Infinite
Step-by-step explanation:
To find - Determine whether each of these sets is countable or uncountable. For those that are countably infinite, exhibit a one-to-one correspondence between the set of positive integers and that set.
(a) integers not divisible by 3.
(b) the real numbers with decimal representations consisting of all 1s.
Proof -
a)
Let
A be the set of integers that are not divisible by 3
Now,
A is countably infinite.
The one-to one correspondence between the set to positive integers and A be -
f(n) = 3(n/4 - 1) + 1 if n is divisible by 4
= 3(n-1)/4 + 2 if n - 1 is divisible by 4 and n ≥ 1
= -[ 3(n-2)/4 + 1] if n - 2 is divisible by 4 and n ≥ 2
= -[ 3(n-3)/4 + 2] if n - 3 is divisible by 4 and n ≥ 3
b)
Let B be the set of the real numbers with decimal representations consisting of all 1s.
Now,
B is countably infinite.
The one-to one correspondence between the set to positive integers and B be -
When the function listed positive number, then we will list the corresponding negative number immediately after it before listing the next positive number.
Now,
The set of real number starts with 1, 11, 111, ... and the decimal representation consisting all 1s is -
1.1, 1.11, 1.111, 1.1111 .........(countable)
11.1, 11.11, 11.111, 11.1111 ........(countable)
111.1, 111.11, 111.111, 111.1111 ......(countable)
and so on
So,
There are countable infinite elements

Find the value of k.
Round to 2 decimal values.
Answer:
The normal distribution is explained for the solution of this question.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean = 25, Standard Deviation = 3.8
This means that [tex]\mu = 25, \sigma = 3.8[/tex]
So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{X - 25}{3.8}[/tex]
If P(X > k) = a
We have to find [tex]X = k[/tex] when Z has a pvalue of 1 - a.
If P(X < k) = a
We have to find [tex]X = k[/tex] when Z has a pvalue of a.

Solve and explain. Sue orders pictures from her photographer. Each picture costs $8. A one-time shipping fee of $7 is added to the cost of every order. The total cost of Sue’s order is $31. How many pictures did Sue order?
Answer:
3 pictures
Step-by-step explanation:
Please see the attached pictures for the full solution.
☆ Since the shipping fee is a one-time fee, for an order, Sue only pays $7 once and the rest of the cost would be due to the number of pictures she ordered.
Point S is between points R and T. Given that
RS ST and RS = 16, what is RT?
Answer:
32
Step-by-step explanation:
Reason: point S is between points are and t
Meaning that Line RS≅ST
So if RS=16 then ST=16
To find RT we just add ST and RS
16+16=32
Therefore RT=32

What is the surface area of the prism?
Answer:
Step-by-step explanation:
Since we know the total surface area of a prism is equal to the sum of all its faces, i.e., the floor, walls, and roof of a prism. Therefore, the surface area of a prism formula is given as: Total surface area of a prism = 2 x area of the base + perimeter of the base x Height.

find the area of an equilateral triangle with sides 6m.
Answer: 12 m²
Step-by-step explanation:
Find height first:
It would be a 3-4-5 triangle, (or you could use Pythagorean theorem) so the height would equal 4.
Equation:
[tex]\frac{1}{2}bh[/tex] = [tex]\frac{1}{2}[/tex](6)(4) = 12 m²
