Answer:
There are 9 geese and 18 horses.
Step-by-step explanation:
Step 1: Make equations.
g ... number of geese
h ... number of horses
First equation: There are 27 animals in the barn.
g + h = 27
Second equation: There are 90 legs in all.
We know geese have two legs and horses 4.
2g + 4h = 90
Step 2: Solve the system of equations.
g + h = 27 (first equation)
2g + 4h = 90 (second equation)
Let's express g in terms of h in first equation.
g + h = 27
g = 27 - h
Now let's substitute g in second equation with g in first equation.
2g + 4h = 90
2(27 - h) + 4h = 90
And solve for h.
54 - 2h + 4h = 90
54 + 2h = 90
2h = 90 - 54
2h = 36
h = 18
Let's substitute the value of h back to first equation to get g.
g = 27 - h
g = 27 - 18
g = 9

Draw a quadrilateral that has two 60 degree angles and two 120 degree angles.
Answer:
Step-by-step explanation:
Draw a straight line.
Then draw 2 lines of equal length from the 2 ends of the line at angles of 120 degrees going up and apart.
Then draw the fourth line joining the ends of these 2 lines.
The 2 angles formed will equal 60 degrees.
The quadrilateral formed is a trapezoid.

Consider the summary statistics from the previous question. The residents pay $0.015 per gallon of usage. What is the standard deviation of the amount paid for monthly water usage
The standard deviation of the amount paid for monthly water usage is $35.25
How to determine the standard deviation?From the summary statistics, we have:
Standard deviation, σ = 2350
Rate = $0.015
The standard deviation of the amount is calculated using:
σ = Standard deviation * rate
This gives
σ = 2350 * $0.015
Evaluate
σ = $35.25
Hence, the standard deviation of the amount paid for monthly water usage is $35.25

For function f(x), which pair of limits would verify the existence of a vertical asymptote at x = –1?
This shows that for the function f(x), the pair of limits that would verify the existence of a vertical asymptote at x = –1 is expressed as:
[tex]\lim_{x \to -1^+} a_n = \lim_{x \to -1^-} a_n =f(c)[/tex]
Limit of a functionFor the limit of a function to be continuous at a point x = a, the left hand limit of the function must be equal to the right hand limit.
Mathematically, the expression below must be true

Which of the following inequalities matches the graph?
Answer:
y ≥ 1
Step-by-step explanation:
The graph of an inequality is illustrated, with a solid horizontal line passing through point (0, -1) and shading above the line.
It indicates that the line equation is:
For various x values, y=-1.
Also, because the darkened region is above the line, i.e. towards the origin, it must pass the 0-test.
As a result, the inequality is:
y≥-1

Answer:
The correct answer is dilate by a scale factor of 2 and reflect over the x-axis.
Step-by-step explanation:
We can clearly see that there was no rotation or translation between the 2 triangles so we can deduct the second and fourth answer. We can also see that the triangle reflects over the x-axis and not the y-axis so the second answer is incorrect. Leaving the first one, which is the correct answer.

Tim is 5 feet tall and casts a shadow that is 2 feet long. He stands next to a tree that is 30 feet tall. How long is the shadow the tree casts?
Answer:
12 ft
Step-by-step explanation:
Tim Height: Tim Shadow
5ft : 2ft
Tree Height: Tree Shadow
30ft : ?ft
Using this knowledge, we can compare Tim's Height to the Tree's Height. The tree's height is 6 times more than Tim (5x6=30). We can find the shadow of the tree if we multiple tim's shadow by 6.
Therefore, 2ft x 6 = 12ft
The Tree's Shadow is 12ft.

Answer:
396 = 341q-333
Step-by-step explanation:
396 is (396 =)
the quantity q times 341 (341q)
333 subtracted from (-333)
Answer:
341q - 333 = 396
Step-by-step explanation:
multiply q and 341, you get 341q
a number that is subtracted from another number is the same as saying 2 is subtracted from 5 gives you 3, which can be laid out as 5 - 2 = 3
therefore your equation will be 341q - 333 = 396
extra information :
341q = 396 + 333
341q = 729
q = 729/341
q = 2.137829912

Abc is isosceles. ab=3x-4 and bc=5x-10 what is ab
Answer:
AB=5
Step-by-step explanation:
3x-4=5x-10
-4=2x-10
6=2x
3=x
AB= 3(3)-4
9-4
5
Answer:
ab = 5.
Step-by-step explanation:
As the 2 sides are equal in length:
3x - 4 = 5x - 10
3x - 5x = -10 + 4
-2x = -6
x = 3.
So ab = 3x-4 = 3(3)-4
= 5.
