Sal was asked by his teacher to
compare the numbers 153.098 and
153.408. Which is the correct way to
compare these two numbers?
A. 153.098 > 153.408
B. 153.098 = 153.408
C. 153.408 < 153.098
D. 153.408 > 153.098
Answer:
153.098
153.408
When we look at these numbers, we want to see which one has the greatest digit.
Shown below, I'm going to compare both numbers and start from the hundreds place and gradually go further into the other digits until we've seen which number is the greatest.
153.098:
1
153.408:
1
153.098:
15
153.408:
15
153.098:
153
153.408
153
153.098:
153.0
153.408
153.4
Now, we can automatically know that 153.408 is the greatest because the 4 in the tenths place is bigger than 0 in the tenths place in the other number.
So 153.408 > 153.098, D is your answer.

B.
The function is an odd function because .
C.
The function is an even function because .
D.
The function is an odd function because its graph is symmetric about the y-axis.
Answer:
B. The function f(x) = tan(x) is an odd function because f(-x) = -f(x)
Step-by-step explanation:
The function f(x) = tan(x) is odd as [tex]f(-x) = -f(x)[/tex] so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.
What are functions?The function is a relation used to determine a value f(x) for a given x using an expression in x.
What are even functions?An even function is when f(x) = f(-x). It is symmetric along the y-axis.
What are odd functions?An odd function is when f(-x) = -f(x). It is symmetric along the x-axis.
How do we solve the given question?We are dealing with the function f(x) = tan(x).
We calculate f(-x) = tan(-x) = -tan(x) = -f(x).
∴ The function f(x) = tan(x) is an odd function, and odd functions are symmetric about the origin.
∴ The function f(x) = tan(x) is odd as [tex]f(-x) = -f(x)[/tex] so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.

Two squares have sides of 3 & 6. what is the ratio of their perimeter
Answer:
Step-by-step explanation:
Square with side (s) = 3
P = 4s
s = 3
P = 4*3
P = 12
Square with side (s) = 6
P = 4s
s = 6
P = 4 * 6
P = 24
Answer
It is asking for the ratio of P(with side = 3)/ to P(with side = 6)
P(3) /P(6) = 12/24 = 1/2s(3) / s(6) = 3/6 = 1/2So the perimeter ratio is 1/2
The side ratio is 1/2
They are the same.

Two angles are supplementary. The measure of the larger angle is 12 less than 3 times the measure of the smaller angle.Find the measure of each angle
Answer:
48 , 132
Step-by-step explanation:
Let smaller angle = x
Larger angle = 3x - 12
x & (3x - 12) are supplementary
So, x + 3x - 12 = 180°
4x - 12 = 180
4x = 180 +12
4x = 192
x = 192/4
x = 48°
Larger angle = 3*48 - 12 = 144 - 12 = 132
Answer: The measure of the smaller angle is 48,and the larger angle is 132.

Part 3: Construct a prism from the above regular hexagon. The height of the hexagonal prism is 5 feet. Find the surface area and the volume of this prism.
The volume of the hexagonal prism is the amount of space in it.
The surface area is 369.9 square feetThe volume is 831.4 cubic feetHow to determine the surface area?From the complete question, we have:
Length (l) = 8
Height (h) = 5
The surface area of the hexagonal prism is:
[tex]A=6lh+3l^2\sqrt 3[/tex]
So, we have:
[tex]A=6*8*5+3*5^2\sqrt 3[/tex]
Evaluate
[tex]A = 369.9[/tex]
Hence, the surface area is 369.9 square feet
How to determine the volume?The volume of the hexagonal prism is:
[tex]V = \frac{3\sqrt 3}{2} * l^2h[/tex]
So, we have:
[tex]V = \frac{3\sqrt 3}{2} * 8^2 * 5[/tex]
Evaluate
[tex]V = 831.4[/tex]
Hence, the volume is 831.4 cubic feet

Marina babysits her neighbors' kids once a week and earns $40 each night. She loves coffee so she treats herself three times a week by buying a $5 latte at her favorite coffee shop. Marina wants to buy a new laptop for herself which will cost $800 and has already saved $200. If she continues her spending habits, how many months will it take Marina to save enough money to buy the laptop?
Answer:
24weeks
Step-by-step explanation:
So if she spends 5$ three times a week she spends 15$ a week
She babysits once a week for 40$
That means that she saves 25$ from babystitting each week
As she already has saved 200$, she only lacks 600$ for the purchase
600$ / (25$/week) = 24 weeks
If she stops buying coffee it will instead only take her 15 weeks to buy a new laptop

Ollie has installed security lights on the side of his house that are activated by a sensor. The sensor is located at point C directly above point D. The area covered by the sensor is shown by the shaded region enclosed by triangle ABC. The distance from A to B is 4.5 m and the distance from B to C is 6 m. Angle AĈB is 15°.
Answer:
20.19°
Step-by-step explanation:
Find the diagram to the question attached. We are to look for <CAB
Applying sine rule on ΔABC:
[tex]\frac{4.5}{sin15^0} = \frac{6}{sin<CAB}[/tex]
cross multiply
[tex]4.5 * sin<CAB =6 sin15^0\\\\sin<CAB = \frac{6sin15^0}{4.5}\\ \\sin<CAB = \frac{6*0.2588}{4.5}\\ \\sin<CAB = \frac{1.5529}{4.5}\\\\sin<CAB = 0.3451\\\\<CAB = sin^{-1}0.3451\\[/tex]
[tex]<CAB = 20.19^0\\[/tex]
Hence the angle <CAB is 20.19°
The angle ∠CAB is 20.19° and the distance (d) Ollie is from the entrance to his house when he first activates the sensor is 5.77 m.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
Ollie has installed security lights on the side of his house that is activated by a sensor.
The sensor is located at point C directly above point D.
The area covered by the sensor is shown by the shaded region enclosed by triangle ABC.
The distance from A to B is 4.5 m and the distance from B to C is 6 m.
The angle ACB is 15°.
The ∠CAB is ∠A.
We know that the sine rule
[tex]\dfrac{a}{\sin A} =\dfrac{b}{\sin B} = \dfrac{c}{\sin C}[/tex]
We have
[tex]\dfrac{AB}{\sin C} \ \ = \dfrac{BC}{\sin A} = \dfrac{AC}{\sin B}\\\\\\\dfrac{4.5}{\sin 15^o} = \dfrac{6}{\sin A} = \dfrac{b}{\sin B}[/tex]
From the first two, we have
[tex]\dfrac{4.5}{\sin 15^o} = \dfrac{6}{\sin A} \\\\\sin A = \dfrac{6}{4.5} \times \sin 15^o\\\\A \ \ \ \ = 20.19^o[/tex]
We know that the sum of the angle is 180 degrees. Then we have
∠A + ∠B + ∠C = 180°
20.19° + ∠B + 15° = 180°
∠B = 144.81°
Then the value of b will be
[tex]\dfrac{4.5}{\sin 15^o} = \dfrac{b}{\sin 144.81^o}\\\\\\b \ \ \ = 10.02[/tex]
Then the distance (d) Ollie is from the entrance to his house when he first activates the sensor will be
d = b × sin 144.81°
d = 10.02 × sin 144.81°
d = 5.77 m

Marshall works at an animal shelter. He makes sure all the cats are vaccinated. In July, 56 of the cats entering the shelter had already been vaccinated. Based on this result, he predicts that if 100 cats entered the shelter, 80 of the cats would have already been vaccinated. How many cats entered the animal shelter in July?
Answer: 70 animals
Step-by-step explanation:
Since Marshall predicted that if 100 cats entered the shelter, 80 of the cats would have already been vaccinated . This means that 80/100 = 4/5 of the animals that enter the shelter are vaccinated.
Let the animals that enter in July be y. This will be:
4/5 × y = 56
0.8y = 56
y = 56/0.8
y = 70
70 animals entered in July
