Answer:
the answer is 32:1
Step-by-step explanation:
288 divided by 9 = 32 9 divided by 9 = 1 288:9=32:1The ratio of 288 divided by 9 is 32:1 .
Given,
288/9
Here
288 divided by 9
Firstly divide by the smallest factor of 288 and 9 .
Thus the smallest factor will be 3 .
So,
288/3 = 96
9/3 = 3
Now further simplify,
96/3
The resultant will be
96/3
=32/1
So the ratio will be,
288:9=32:1

If Θ is between 0° and 90° and tanθ = 7/8 find cosθ
Since 0° < θ < 90°, you know that cos(θ) > 0.
Recall that
1 + tan²(θ) = sec²(θ)
and also that
sec(θ) = 1/cos(θ)
So if cos(θ) > 0, we also have 1/cos(θ) = sec(θ) > 0.
Then
sec(θ) = + √(1 + tan²(θ))
sec(θ) = √(1 + (7/8)²)
sec(θ) = √113 / 8
so that
cos(θ) = 1 / (√113 / 8) = 8 / √113

If a² + b² = c², then which of the following are also true? Select all that apply
Options
a² - b² = c²
b² + a² = c²
c² + a² = b²
c² - a² = b²
c² - b² = a²
Answer:
Option 2 , 4 & 5 are true.
Step-by-step explanation:
● Option 2 is equivalent to a² + b² = c².
● Option 4 & 5 can be found by :-
Substracting a² from both the L.H.S. & R.H.S. (It will match with Option 4)Or substracting b² from both the L.H.S & R.H.S. (It will match with Option 5)

Answer:
x = 55
Step-by-step explanation:
First set the equations to equal eachother since theyre corresponding.

D. P(-4,4) and S(-3,-2)
9514 1404 393
Answer:
D. P(-4,4) and S(-3,-2)
Step-by-step explanation:
The first coordinate is the number of units right of the vertical y-axis. Point P is 4 units left, so has an x-coordinate of -4. (Eliminates choices A and B)
The second coordinate is the number of units above the horizontal x-axis. Point P is 4 units up, so has a y-coordinate of +4. (Eliminates choice C)
The coordinates of points P and S are ...
P(-4,4) and S(-3,-2) . . . . . matches choice D
Answer:the answer is D. P(-4,4) and S(-3,-2)

Given:
The quadratic equation is
[tex]y=3x^2-18x+15[/tex]
To find:
The x-coordinate and y-coordinate of the vertex.
Solution:
If a quadratic function is defined by [tex]f(x)=ax^2+bx+c[/tex], then the vertex is defined as:
[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]
If [tex]a<0[/tex], then the function has a maximum at the vertex and ff [tex]a>0[/tex], then the function has a minimum at the vertex.
We have,
[tex]y=3x^2-18x+15[/tex]
Here, [tex]a=3,b=-18,c=15[/tex].
Since [tex]a=3>0[/tex], therefore the function has a minimum at the vertex. So, fill min in first blank.
Now,
[tex]\dfrac{-b}{2a}=\dfrac{-(-18)}{2(3)}[/tex]
[tex]\dfrac{-b}{2a}=\dfrac{18}{6}[/tex]
[tex]\dfrac{-b}{2a}=3[/tex]
Putting x=3 in the given function, we get
[tex]y=3(3)^2-18(3)+15[/tex]
[tex]y=27-54+15[/tex]
[tex]y=-12[/tex]
Therefore, the vertex is at point (3,-12).

3. (2 marks) A real estate agent has 8 keycards to open new model homes. Only one keycard will open any specific model home. If 40% of these homes are usually left unlocked, what is the probability that the real estate agent can get into a specific home if the agent chooses 3 keycards at random before leaving the office
Answer:
0.625
Step-by-step explanation:
We are told that the agent has 8 keycards.
We are also told that only one of the keycards can open each home.
Now, if the agent took 3 out of the 8 keycards with him, it means that;
Probability of opening by the keycards = ⅜
We are told that 40% or 0.4 of these homes were left unlocked.
This means that 60% or 0.6 are those that will require a key card.
Thus, probability of agent getting into a specific home is;
P(agent getting into a specific home) = 0.4 + 0.6(⅜)
P(agent getting into a specific home) = 0.4 + 0.6(0.375) = 0.625

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 122 and standard deviation of 22 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. a. Around what percentage of adults in the USA have stage 2 high blood pressure
Answer: 4.27% of adults in the USA have stage 2 high blood pressure.
Step-by-step explanation:
Let x be a random variable that denotes a person with high blood pressure .
Given: Average blood pressure: [tex]\mu=122[/tex]
Standard deviation: [tex]\sigma=22[/tex]
Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher.
The probability that an adult in the USA have stage 2 high blood pressure:
[tex]P(x\geq160)=P(\dfrac{x-\mu}{\sigma}}\geq\dfrac{160-122}{22})\\\\=P(z\geq1.72)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.72)\\\\=1-0.9573\ \ [By\ p-value\ table]\\\\=0.0427=4.27\%[/tex]
Hence, 4.27% of adults in the USA have stage 2 high blood pressure.

plz help 20 points if you get it right and I will give you brainliest
Answer:
The first one cannot be simplified
reason: usually when simplifying an expression you combine like terms but in the given expression there are no like terms
An example of like terms would be 6a and 9a
Essentially what i am saying is that the variables have to be the same in order for them to be combined
The second one is 36r
This is the answer because they tried to combine like terms that aren't similar
r and f are not the same variable therefore they cannot be combined

using algebra, what is the first step in solving the following equation for the value of x;
8x + 12 = 52.
a) perform the inverse of multiplying by 8 (divide by 8) b) subtract 12 to form the identity (0) and cancel the 12. c) using the property of equality and do the same thing on both sides of the equal sign.
d) isolate the variable
Answer:
subtract 12 to form the identity (0) and cancel the 12.
Step-by-step explanation:
Subtract 12 from both sides.
8x=52−12
2 Simplify 52-1252−12 to 4040.
8x=40
3 Divide both sides by 88.
x=\frac{40}{8}
40/8
simplify 40 over 8 to 5
x=5
Answer:
×=5
Step-by-step explanation:
-12 both sides
then divide 8 both sides
40/8 =5
