What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
From the given diagram,
63 + (15x - 3) = 180° (sum of angles on a straight line)
15x = 120
x = 8
m∠1 = 8x + 7. (opposite angles are equal)
m∠1 = 8(8) + 7 = 71°.

A) 21
B) 33
C) 54
D)

Answer:
33
Step-by-step explanation:
Usatestprep
The length of AC is 33. The correct option is B) 33
The diagram that illustrates the question is shown in the attachment below:
From the question,
We are to determine the length of AC.
To determine the length of AC,
First, we will determine the value of x.
From Triangle proportionality theorem,
We have that
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
Then, from the diagram, we can write that
[tex]\frac{x-3}{x-7}=\frac{x+12}{x}[/tex]
Now, we will solve for x
[tex]\frac{x-3}{x-7}=\frac{x+12}{x}[/tex]
This becomes
[tex]x(x-3) = (x-7)(x+12)[/tex]
Clearing the brackets
[tex]x^{2} -3x = x^{2} +12x-7x-84[/tex]
Simplifying, we get
[tex]x^{2} -3x = x^{2} +5x-84[/tex]
Subtract x² from both sides
[tex]x^{2}-x^{2} -3x = x^{2}-x^{2} +5x-84[/tex]
[tex]-3x = 5x-84[/tex]
Then, subtract and 5x from both sides
[tex]-3x-5x = 5x-5x-84[/tex]
[tex]-8x = -84[/tex]
Now, divide both sides by -8
[tex]\frac{-8x}{-8}=\frac{-84}{-8}[/tex]
∴ [tex]x = 10.5[/tex]
From the diagram, we can observe that the length of AC is
AC = x +12 +x
Put the value of x into the above equation
That is,
AC = 10.5 + 12 + 10.5
∴ AC = 33
Hence, the length of AC is 33. The correct option is B) 33

Alvin has a prism-like water tank whose base area is 0.9 square meters and height is 0.6 meters. He wants to
buy guppy fish, and the pet store owner tells him to make sure their density in the tank isn't more than 5 fish per
cubic meter.
How many fish can Alvin get, at most?
Answer:
Step-by-step explanation: The answer is 2 fish
Alvin can have at most 2 fish in his tank to ensure the density doesn't exceed 5 fish per cubic meter.
To find out how many guppy fish Alvin can get for his water tank, we need to calculate the volume of the tank first. Given that the tank is prism-like with a base area of 0.9 square meters and a height of 0.6 meters, we can use the formula for the volume of a prism:
Volume = Base Area × Height
Substituting the given values:
Volume = 0.9 m² × 0.6 m
Volume = 0.54 cubic meters
Now, since the pet store owner advised Alvin not to exceed a density of 5 fish per cubic meter, we can calculate the maximum number of fish Alvin can get by multiplying the volume of the tank by the maximum density:
Max number of fish = Volume × Maximum density
Max number of fish = 0.54 m³ × 5 fish/m³
Max number of fish = 2.7 fish
However, since we can't have a fraction of a fish, Alvin can have at most 2 fish in his tank to ensure the density doesn't exceed 5 fish per cubic meter.
With which values of the argument the function acquires a value equal to144
[tex]y = \frac{1}{9x {}^{2} } [/tex]
Answer:
[tex]x=\frac{1}{36} \, \,and\,\, x=-\frac{1}{36}[/tex]
Step-by-step explanation:
To find at which values of the argument the function renders 144, we need to solve for "x" in the equation when y is 144:
[tex]y=\frac{1}{9\,x^2}\\144=\frac{1}{9\,x^2}\\144\,x^2=\frac{1}{9} \\x^2=\frac{1}{9\,(144)} \\x^2=\frac{1}{1296} \\x=+/-\sqrt{\frac{1}{1296} } \\x=+/-\frac{1}{36}[/tex]
Therefore there are two solutions: one is 1/36 and the other one is its opposite; -1/36
Answer:
Step-by-step explanation:
hello :
solve : 1/9x² = 144
x² = 144×9
x² =(12×3)² means : x² =36²
so : x=36 or x= -36
j+2 = 3k+5 in terms of k
Answer:

Given:
m∠APB = 19°
To find:
The arc measure of DBC.
Solution:
∠APB and ∠DPC are vertical angles.
By vertical angle theorem:
m∠APB = m∠DPC
m∠DPC = 19°
DB is the diameter of the circle.
Angle measure of diameter = 180°
m∠DPB = 180°
m∠DPC + m∠CPB = m∠DPB
19° + m∠CPB = 180°
Subtract 19° from both sides.
19° + m∠CPB - 19° = 180° - 19°
m∠CPB = 161°
The measure of central angle is equal to the measure of intercepted arc.
m∠CPB = m(ar CPB)
m(ar CPB) = 161°
The arc measure of DBC is 161°.

A freight elevator has a maximum weight limit of 3,200
pounds. The elevator is being loaded with crates that each
weigh 300 pounds. The forklift being used to move the
boxes weighs 175% as much as one crate. How many
crates can fit onto the freight elevator? Select all that
apply.
A. 6 crates
B. 8 crates
C. 10 crates
D. 12 crates
Answer:
A and B
Step-by-step explanation:
Firstly you must establish the weight of the forklift.
You can do this by multiplying 300 by 1.75
This is 525 pounds
Now subtract 525 from 3200
This gives you 2675
Now you must Divide 2675 by 300
Then round down to find out the total number of crates that can be loaded
This is 8
So the Answer is A and B
The maximum number of crates that can fit onto the elevator is 8, given the weight constraints. Here option B is correct.
Maximum weight limit of the elevator = 3,200 pounds.
Weight of each crate = 300 pounds.
Weight of the forklift = 175% of the weight of one crate = 1.75 * 300 = 525 pounds.
To find out how many crates can fit onto the elevator, we need to consider both the weight of the crates and the weight of the forklift.
Let's denote the number of crates as x. The total weight on the elevator can be represented by the equation:
300x + 525 ≤ 3200
Solving for x:
300x + 525 ≤ 3200
300x ≤ 2675
x ≤ 8.92
Since we can't have a fraction of a crate, the maximum number of crates that can fit onto the elevator is 8. Here option B is correct.

a pizzeria stores flour in a 5-gallon container. Each pizza they make uses 7 cups of flour. can the cook at pizzeria make 12 pizzas without refilling the canister?
the canister holds cups and they need cups of flour to make 12 pizzas?
Answer:
The cook CANNOT make 12 pizzas without refilling the canister
Step-by-step explanation:
Please see the attached files for explanation
The pizzeria cook can make 12 pizzas without refilling the flour container.
The pizzeria stores flour in a 5-gallon container. Each pizza uses 7 cups of flour. To determine if the cook can make 12 pizzas without refilling, we need to calculate if 5 gallons of flour is enough.
Calculation:
5 gallons = 640 cups (since 1 gallon = 128 cups)
12 pizzas x 7 cups/pizza = 84 cups needed for 12 pizzas
Since the canister holds 640 cups and only 84 cups are needed for 12 pizzas, the cook can indeed make 12 pizzas without refilling.

a rectangle container messuring 20cm by 14.5cm by 10.5cm is filled with filled with water to its brim. if 300cm are drained out of the container, what will be the hight of the water level?
Correction
If 300cm3 are drained out of the container,
Answer:
9.47 cm
Step-by-step explanation:
Volume of the container is given by, V= lwh where l is the length of the container, w is width and h is height.
When filled with water, taking l as 20cm, width as 14.5 cm and height as 10.5cm, the volume of container is
V=20*14.5*10.5=3045 cm3
When 300 cm3 is drained, the remaining volume is 3045-300=2745 cm3
Since the length and width is constant but height varries, the new height will be
20*14.5*H=2745
H=2745/290=9.4655172413793
Rounded off, H=9.47 cm
A=1/2 h(b+c) solve for b
Answer:
b = [tex]\frac{2A-hc}{h}[/tex]
Step-by-step explanation:
Given
A = [tex]\frac{1}{2}[/tex] h(b + c)
Multiply both sides by 2 to clear the fraction
2A = h(b + c) ← distribute
2A = hb + hc ( subtract hc from both sides )
2A - hc = hb ( divide both sides by h )
[tex]\frac{2A-hc}{h}[/tex] = b
