The unknown variable, h of the equation is 18
How to find variable in an equation?A variable is a number represented by a letter in an equation.
The unknown variable in the equation is variable h.
Therefore, let's find the value of h.
A = 1 / 2 h(B + b)
where
A = 153B = 10b = 7Therefore, let's substitute the known values in the equation.
153 = 1 / 2h(10 + 7)
153 = 1 / 2 h(17)
153 = 17 / 2 h
cross multiply
153 × 2 = 17h
306 = 17h
divide both sides by 17
h = 306 / 17
Therefore,
h = 18

for a population with a standard deviation of σ = 6, what is the z-score corresponding to a score that is 12 points above the mean?
The z-score corresponding to a score that is 12 points above the mean is 2.
The z-score is a numerical measurement used in statistics to determine the sample data value's relationship to the mean of a group of values, measured in terms of standard deviation from the mean. It is measured as the difference of the sample data value and the sample mean over the standard deviation, such that
z-score = (x – μ) / σ
where x = sample data value
μ = mean
σ = standard deviation
If the sample score is 12 points above the mean, then (x – μ) = 12.
(x – μ) = 12
σ = 6
Substitute the values to the z-score formula.
z-score = (x – μ) / σ
z-score = 12/6
z-score = 2

[tex]\begin{cases}s + h = 40\\18s + 14h = 700 \end{cases}[/tex]
Step-by-step explanation:
Given information:
40 = Total number of scarves and hats sold.$700 = Total amount made from the sale.$18 = Charge for each scarf.$14 = Charge for each hat.Define the variables:
Let s = number of scarves sold.Let h = number of hats sold.Create an equation for the total number of scarves and hats sold:
⇒ s + h = 40
Create an equation that represents the total amount made from sales considering the cost per item:
⇒ 18s + 14h = 700

Directions: Write the slope form of the equation with the given information.
13) through (3,4) and (5,-2)
Answer:
y=-3x+13
Step-by-step explanation:
step one you will need to find the slope by the Y2 minus y1 all over x2 minus X1 formula. so you would have -2 - 4 all over 5 - 3 . you will get -6 over 2 which is equal to -3 . that means that -3 is the slope .
Step 2 you can find the equation with the point slope form formula . the point slope form formula is y-y1=m(x-x1). by substituting your values into these equation you can find the equation of this line . you can substitute any point into it as long as it is on the line . let's use (3,4) where 3=x1 and 4=y1.
step 3. simplify. you will get y-4=-3(x-3). keep in mind I substituted -3 into the equation because -3 is the slope.
you can simplify this if you want to . you will get y=-3(x-3)+4. it becomes through foiling, y=-3x+9+4. it simplifies to y=-3x+13.

Answer:
∠ 2 = 140°
Step-by-step explanation:
the left base angle in the triangle and 110° are a linear pair and sum to 180°
base angle + 110° = 180° ( subtract 110° from both sides )
base angle = 70°
the 2 sides of the triangle are congruent so Δ is isosceles with base angles congruent.
the vertex of the Δ is then
(180 - 70 - 70)° = 180° - 140° = 40°
the vertex and ∠ 2 are a linear pair and sum to 180° , that is
∠ 2 + 40° = 180° ( subtract 40° from both sides )
∠ 2 = 140°

How many toys would Patricia build in 10 hours if she built 5 toys
every 6 minutes?
Answer:
500
Step-by-step explanation:
she can build 5 in 6 minutes. 6 × 10 is 1 hour
so you would do 5 × 10 = 50
then multiply 50 × 10 hours = 500 toys
Answer:
Patricia will build 500 toys in 10 hours
Step-by-step explanation:
5 toys ? toys
--------- = ----------
6 minutes 10 hours
so we would turn the hours into minutes which would be
600 minutes.

what is a set of relations
The relation is the relationship between two or more sets of values. Suppose, x and y are two sets of ordered pairs. If set x has a relation with set y, then the values of set x are called domain whereas the values of set y are called range. A relation from a set A to a set B is a subset of A×B. Hence, a relation R consists of ordered pairs (a,b), where a∈A and b∈B. If (a,b)∈R, we say that is related to, and we also write aRb. A connection between the elements of two or more sets is a relation. The sets must be non-empty. A subset of the Cartesian product also forms a relation R. A relation may be represented either by the Roster method or by the Set-builder method.

Roaring Zoo has 68 different species of birds. Because of cold weather, only 24 species stayed at the zoo, while the others were transported to the barn until warmer weather returned.
Which equation shows how many species of birds were transported?
b + 68 = 24
b − 68 = 24
b + 24 = 68
b − 24 = 68
Answer: b + 24 = 68
Step-by-step explanation:
we are told the zoo has 68 different species of birds so the equation will be = 28. The answers showing = 24 are already wrong.
transported means they are taken away, so we have to subtract 24 (animals that stayed in the zoo) to find b which are the remaining species moved to the barn.
b + 24 = 68
- 24 -24
b = 44 (transported to the barn)
24 ( stayed in the zoo)
68 ( total number of species of birds)
The correct expression to show the species of transported birds will be;
⇒ b + 24 = 68
Where, b is the number of transported birds.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Total number of birds in Roaring Zoo = 68
Number of stayed birds in Zoo = 24
Let number of transported birds = b
Then, We can formulate;
Total number of birds = Stayed birds + Transported birds
Substitute all the values, we get;
⇒ 68 = 24 + b
Therefore,
The correct expression to show the species of transported birds will be;
⇒ b + 24 = 68

Find the slope of the line that contains the given point
Answer:
(2, 1) and (4, 2): [tex]\frac{1}{2}[/tex]
(-4, 5) and (-3, -7): [tex]-12[/tex]
Step-by-step explanation:
Hello! Let's help you with that problem there!
So we know that in a slope intercept form, it is depicted as [tex]y=mx+b[/tex]. There are two ways to essentially find m, which is slope in this case. The first method is the [tex]\frac{rise}{run}[/tex] method. This is typically used when you have a graph to look off from and it's just a matter of counting the displacement from one point to another.
However, there is another way to find the slope given 2 points and that is what we are going to do here, since we have no graph to reference and have all the relevant information to find the slope using this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
With this formula, we can plug in the coordinate values and solve for the slope!
(2, 1) and (4, 2):
[tex]m=\frac{2-1}{4-2}[/tex]
[tex]m=\frac{1}{2}[/tex]
Therefore, the slope of these points is [tex]m=\frac{1}{2}[/tex]
(-4, 5) and (-3, -7):
[tex]m=\frac{-7-5}{-3-(-4)}[/tex]
[tex]m=\frac{-12}{1}[/tex]
[tex]m=-12[/tex]
Therefore, the slope of these points is [tex]m=\frac{-12}{1}[/tex] or [tex]m=-12[/tex]
A straight line, L2, is parallel to the straight line L1 and passes through the point (0,-5).
Find an equation of the straight line L2.
Based on the straight line being parallel to the line, L1, and the gradient, the equation of the straight line L2 is y = 2x - 5
How to find the equation of the line?The equation of a straight line takes the form:
y = mx + b
Where:
m = slope
b = y - intercept
The slope is the same as the gradient and parallel lines have the same gradient. The gradient of L2 is therefore 2 as well.
Use this gradient and the point (0, -5) to find the y - intercept:
-5 = 2(0) + y - intercept
y - intercept = -5
The equation of the line is:
y = 2x - 5

How many cows and chickens does the farmer have in the farm?
Each chicken has two legs and each cow has four legs. The farmer has a total of 216 legs among all the animals, which are 80. Then, we can represent the situation with the following system of linear equations:
x + y = 80
4 · x + 2 · y = 216
Where:
x - The number of cows.y - The number of chickens.The system can be solved easily by some algebraic handling:
x = 80 - y
4 · (80 - y) + 2 · y = 216
320 - 4 · y + 2 · y = 216
320 - 2 · y = 216
