The areas of two similar triangles are 18cm^2 and 8cm^2. One of the sides of the first triangle is 4.5cm. What is the length of the corresponding side of the other triangle? Please answer ASAP!!! Thank you!!!
Answer:
3 cmStep-by-step explanation:
The area is the product of two dimensions, therefore the scale factor is:
A/A' = (b*r*h*r)/(b*h) = r²r² = 18/8r = √9/4 = 3/2 = 1.5The length of the corresponding side will be:
a/a' = ra' = a/ra' = 4.5 / 1.5 a' = 3 cmFind the point of intersection of the lines x-3 = 0 and y-5 = 0.
Answer:
x = 3 and y = 5
Step-by-step explanation:
Given equations are :
x-3 = 0 ....(1)
y-5 = 0 ....(2)
We need to find the point of intersection of the lines.
Add 3 both sides in equation (1).
x-3+3=3
x = 3
Now, add 5 to both sides of the equation.
y-5+5=0+5
y = 5
Hence, the required point of intersection of the lines is x = 3 and y = 5.

Find x in the following triangle
Answer:
hope it helps, twanks you (owo)
Step-by-step explanation:
Solving for X in a Right Triangle
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X
Does 100cm equal 1m
Answer:
True
100cm = 1m ✔️
Step-by-step explanation:
The cm (centimeters) has the key word unit cent in it, which means 100. Like how a century is 100 years, 100 cents are in a dollar, there is 100 percent in 1 whole number, etc.
Based on background knowledge (or from searching it up too), every meter has a hundred centimeters, since the unit cent means 100.
Hence,
100 centimeters does equal 1 meter

Professor Rogers has found that the grades on the nursing final exam are normally distributed with a mean of 64 and standard deviation of 11. a) If the passing grade is 54, what percent of the class will fail
Answer:
18.165%
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ
From the Question above , we are asked to find the percent of the class that will fail if the passing grade is 54.
The percent of the class that would fail is the percent of the class that has a grade less than(<) 54
Hence,
x is the raw score = 54
μ is the population mean = 64
σ is the population standard deviation = 11
For x < 11
z = 54 - 64/11
z = -0.90909
Probability value from Z-Table:
P(x<54) = 0.18165
Converting to percentage
= 0.18165 × 100
= 18.165%
Therefore, If the passing grade is 54, the percent of the class that will fail is 18.165%
I'll mark you brainiest ---- find the range of possible values for the third side of a triangle if given two side lengths. 9yd, 32yd
Answer:
The third side of the triangle must have a length between 23 yd and 41 yd.
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We have to side lengths: y=32 yd and z = 9 yd, thus the range of possible values for the third side x is:
32 - 9 < x < 32 + 9
23 < x < 41
The third side of the triangle must have a length between 23 yd and 41 yd.
3/4(x + 3) = 9
How do I solve this
Answer:
x = 10
Step-by-step explanation:
so first distribute the 3/4 to everything on the inside
3/4x + 1 1/2 = 9
now subtract 1 1/2 on both sides
3/4x = 7 1/2
Now divide both sides by 3/4
x = 7 1/2 divided by 3/4
x = 15/2 divided by 3/4
x = 15/2 times 4/3
x = 5/1 times 2/1
x = 10

Question: A restaurant gets an average of 5.3 complaints per day from its patrons. Use the Poisson distribution formula to find the probability that on a given day the restaurant will receive exactly 4 complaints
Answer:
[tex]P(X=4) = 0.164125[/tex]
Step-by-step explanation:
Given
[tex]\bar{x} = 5.3[/tex] -- average
Required
Determine the probability of receiving 4 complaints in a day
Since, it follows a poisson distribution, the probability is calculated as:
[tex]P(X=x) = \frac{\bar{x}^x * e^{-\bar{x}}}{x!}[/tex]
In this case:
[tex]x = 4[/tex]
So, we have:
[tex]P(X=4) = \frac{5.3^4 * e^{-5.3}}{4!}[/tex]
[tex]P(X=4) = \frac{789.0481 * 0.004992}{4*3*2*1}[/tex]
[tex]P(X=4) = \frac{3.939}{24}[/tex]
[tex]P(X=4) = 0.164125[/tex]
Hence, the probability of exactly 4 complaints is 0.164125 .
