Find a radical expressions for the perimeter of the shaded triangle Simplify the expression.
Answer:20+4√17
Step-by-step explanation:
2 of 3 sides are 16 and 4 units . The angle between them is 90 degrees.
So we can find the length of the third side using Pitagor theorem.
c= SQRT( 16²+4²)= sqrt (256+16)= sqrt (272)
So the perimeter of the shaded triangle is equal to
P= 4+16+sqrt(272)=20+4√17
The radical expressions for the perimeter of the shaded triangle is 20 + 4√17
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a rectangle shown in the picture with dimensions.
Using Pythagoras theorem;
The inclined length = √(4²+16²) = √272 = 4√17
The perimeter of the shaded region = 16 + 4 + 4√17
Perimeter = 20 + 4√17
Thus, the radical expressions for the perimeter of the shaded triangle is 20 + 4√17

Your friend has a mold that holds 3/4 of a cup of root beer if she has six cups of root beer how many popsicles can she make
Answer:
8
Step-by-step explanation:
If you turn 8 into a fraction you'll get 24 / 4
then you divide 24/4 by 3/4 you'll get 8
Answer:
Your friend can make 8 popsicles
Explanation:
Convert any mixed numbers to fractions. Then your initial equation becomes:
6/1 ÷ 3/4 = ?
Applying the fractions formula for division (flip the second fraction and multiply):
6/1 x 4/3 = 24/3
Simplify 24/3, the answer is:
8 popsicles

g Find two positive numbers whose sum is 380 and whose product is a maximum. You MUST use optimization methods to solve this.
Answer:
The first number is 190 and the second number is also 190
Step-by-step explanation:
let the first number = x
let the second number = y
The sum of the numbers is given by;
x + y = 380
y = 380 - x
The objective function is given by;
F = xy
F = x(380 -x)
F = 380x - x²
Take the derivative of the function;
F' = 380 - 2x
Find the critical points;
380 - 2x = 0
2x = 380
x = 380 / 2
x = 190
Determine the second number, y;
y = 380 - x
y = 380 - 190
y = 190

what is 1 3/8 divided by 1/2?
Answer:
2.75 or 2 3/4
Step-by-step explanation:
Answer:
11/4
Step-by-step explanation:
First start by writing the equation using only fractions:
11/8 / 1/2 =
Next, change the sign to multiplication by taking the reciprocal of the second number:
11/8 * 2 =
Then multiply the two numbers together:
22/8 =
And finally, simply the fraction:
11/4
If (Triangle)ABC is similar to (Triangle)EDC, what is the value of x?
Answer:
37.5 (G)
Step-by-step explanation:
Set up a proportion:
[tex] \frac{40}{100} = \frac{15}{x} [/tex]
Next cross multiply
[tex](15)(100) = (40)(x)[/tex]
[tex]1500 = 40x[/tex]
Lastly solve for x by dividing both sides by 40
[tex]\frac{1500}{40} = \frac{40x}{40} [/tex]
[tex]x = 37.5[/tex]

3(x-2)+7=16 simplified
9514 1404 393
Answer:
3x +1 = 16
Step-by-step explanation:
"Simplified" usually means parentheses are eliminated and like terms are combined.
3(x -2) +7 = 16 . . . . . given
3x -6 +7 = 16 . . . . . . parentheses eliminated using the distributive property
3x +1 = 16 . . . . . . . . . constants are combined (simplified equation)

You can solve this in 2 steps:
3x = 15 . . . . subtract 1
x = 5 . . . . . . divide by 3

Answer:
circumference = 150.72cm
area = 1808.64cm²
Step-by-step explanation:
the formula for circumference = 2πr
the formula for area = πr²
24cm is the radius (r)
so therefore
circumference = 2(3.14)(24)
= 150.72cm
area = (3.14)(24)²
= 1808.64cm
im not too great at math- but I think this is correct ^^

A medical school claims that more than 28% of its students plan to go into general practice. To test this claim, a random sample of 130 of the school's students is selected. Of these, 32% of them plan to go into general practice. Find the P-value for this test of the school's claim.
Answer:
The p-value of the test is 0.1314.
Step-by-step explanation:
In this case we need to test the claim made by a medical school that more than 28% of its students plan to go into general practice.
The hypothesis can be defined as follows:
H₀: The proportion of students planning to go to general practice is 28%, i.e. p = 0.28.
Hₐ: The proportion of students planning to go to general practice is more than 28%, i.e. p > 0.28.
The information provided is:
n = 130
[tex]\hat p=0.32[/tex]
Compute the test statistic value as follows:
[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]=\frac{0.32-0.28}{\sqrt{\frac{0.28(1-0.28)}{130}}}\\\\=1.12[/tex]
The test statistic value is 1.12.
Compute the p-value as follows:
[tex]p-value=P(Z>1.12)\\[/tex]
[tex]=1-P(Z<1.12)\\\\=1-0.86864\\\\=0.13136\\\\\approx 0.1314[/tex]
The p-value of the test is 0.1314.

(1 1/2,1) (4,6) (18,12) (0,0) (2 1/2. 3 3/4 )
Answer:
[tex]2.\ \ (4,6)[/tex]
[tex]4.\ \ (0,0)[/tex]
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Step-by-step explanation:
Given
[tex]y = 1\frac{1}{2}x[/tex]
Required
Determine if the given points is on the graph
First,, we rewrite [tex]y = 1\frac{1}{2}x[/tex] as
[tex]y = \frac{3}{2}x[/tex]
[tex]1.\ \ (1\frac{1}{2},1)[/tex]
This can be interpreted as:
[tex]x = 1\frac{1}{2}[/tex]
[tex]y = 1[/tex]
Substitute [tex]x = 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{3}{2}[/tex]
[tex]y = \frac{9}{4}[/tex]
This isn't equal to the given value of y.
Hence: [tex](1\frac{1}{2},1)[/tex] is not a point on the graph
[tex]2.\ \ (4,6)[/tex]
Here,
[tex]x = 4[/tex]
[tex]y = 6[/tex]
Substitute [tex]x = 4[/tex]
[tex]y = \frac{3}{2} * 4[/tex]
[tex]y = \frac{3 * 4}{2}[/tex]
[tex]y = \frac{12}{2}[/tex]
[tex]y = 6[/tex]
This point is on the graph
[tex]3.\ \ (18,12)[/tex]
Here,
[tex]x = 18[/tex]
[tex]y = 12[/tex]
Substitute [tex]x = 18[/tex]
[tex]y = \frac{3}{2} * 18[/tex]
[tex]y = \frac{3 * 18}{2}[/tex]
[tex]y = \frac{54}{2}[/tex]
[tex]y = 27[/tex]
This isn't equal to the given value of y.
Hence: [tex](18,12)[/tex] is not a point on the graph
[tex]4.\ \ (0,0)[/tex]
Here, we have
[tex]x = 0[/tex]
[tex]y = 0[/tex]
Substitute [tex]x = 0[/tex]
[tex]y = \frac{3}{2} * 0[/tex]
[tex]y = 0[/tex]
Hence:
This point is on the graph
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Here
[tex]x =2\frac{1}{2}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Substitute [tex]x =2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{5}{2}[/tex]
[tex]y = \frac{15}{4}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Hence:
This point is on the graph

To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $5.70 per hour. The film club
wants to spend less than $67.50 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
t<5
39 + 5.7t < 67.5
-39
5.7t < 28.5
divide by 5.7
t < 5
Brain weights are normally distibuted with mean 1400.48 grams and standard deviation 106.33 grams. Find the 80th percentile of this distribution.
Answer:
The 80th percentile of the distribution is 1,490.01 grams
Step-by-step explanation:
Here, we want to find the 80% of the distribution
80% means 80/100 = 0.8
We need to get the z-score equivalent to 80th percentile;
This is equal to 0.842
Mathematically;
z-score = (x - mean)/SD
we want to calculate x here;
0.842 = (x - 1400.48)/(106.33)
106.33(0.842) + 1400.48 = x
x = 1,490.00986 which is 1,490.01 grams to 2 decimal places
