What is right triangle?Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
What is Pythagoras theorem?A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular² + base² = hypotenuse²
Given,
Side length of each triangle = 4 feet
Hypotenuse of each triangle = 9 feet
Shared side = x
Given the triangles are right angled,
According to Pythagoras theorem,
a² + b² = c²
Here, a = 4 , b = x , c= 9
Substitute the values in Pythagoras theorem,
4² + x² = 9²
16 + x² = 81
x² = 81 - 16
x² = 65
Taking square root on both sides
x = √65
x = 8.062
x = 8.1 (Rounding nearest tenth)
Hence, the center height of tent is 8.1 feet.

Answers
The scores on a university examination are normally distributed with a mean of 62 and a standard deviation of 11. if the bottom 5% of students will fail the course, what is the lowest mark that a student can have and still be awarded a passing grade? give the answer that is closest to the exact number.
Answers
the z-score is given by:
z=(x-μ)/σ
where:
σ-standard deviation
μ- mean
we are required to evaluate for x, given that P(x<X)=0.05
The value of z that corresponds to 5% will be:
z=-1.65
thus plugging our values we obtain:
-1.65=(x-62)/11
solving for x we get:
-18.15=x-62
thus
x=-18.15+62
x=43.85
x~44
Thus the lowest score is 44
The lowest marks that a student can have and still be awarded a passing grade is 44.
Step-by-step explanation:
Given :
Mean, [tex]\mu = 62[/tex]
Standard Deviation, [tex]\sigma = 11[/tex]
Calculation :
z score is given by,
[tex]z = \dfrac{x-\mu }{\sigma}[/tex] ----- (1)
Value of z corresponds to 5% is,
[tex]z =-1.65[/tex]
from equation (1) we get,
[tex]-1.65=\dfrac{x-62}{11}[/tex]
[tex]x=43.85[/tex]
[tex]\rm x = 44 \;\;(Approx)[/tex]
The lowest marks that a student can have and still be awarded a passing grade is 44.

m∠1=32°
Find: m∠S, m∠T, m∠Q
Answers
__________________________________________________________
Explanation:
__________________________________________________________
To find "m∠Q" :
Consider the triangle formed by ∠D , ∠1, and ∠Q ;
Given m∠1 = 32° ;
and m∠D = 90° (a "right triangle" ; as shown in "image attached" ;
and by definition, all triangles have 3 angles and 3 sides; and all 3 angles of a triangle add up to 180° ;
→ m∠Q = 180 − (90 + 32) = 180 − 122 = 58 ;
_______________________________________________________
Since this is an "isosceles triangle" ;
→ m∠S = m∠Q = 58° .
Since all angles of any triangle add up to " 180° " ;
→ m∠T = 180 − (58 + 58) = 180 − 116 = 64 ;
____________________________________________
Answer: m∠S = 58 ° ; m∠T = 64 ° ; m∠Q = 58 ° .
____________________________________________
Answer:
s=58 degrees, Q=58 degrees, T=64 degrees
Step-by-step explanation:
Consider the triangle formed by ∠D , ∠1, and ∠Q ;
Given m∠1 = 32° ;
and m∠D = 90° (a "right triangle" ; as shown in "image attached" ;
and by definition, all triangles have 3 angles and 3 sides; and all 3 angles of a triangle add up to 180° ;
→ m∠Q = 180 − (90 + 32) = 180 − 122 = 58
Sunny's garden has 9 tomato plants, 5 pepper plants, 3 squash plants, and 6 pumpkin plants. For every 3 tomato plants in Sunny's garden, there is 1 ____ plant.
Answers
from the list of plants there are 3 squash plants
3 squash plants x 3 tomato plants = 9 total tomato plants
the answer is Squash Plants
Answer: Squash plant is the right answer to fill the blank.
Step-by-step explanation:
Since we have given that
Number of tomato plants = 9
Number of pepper plants = 5
Number of squash plants = 3
Number of pumpkin plants = 6
Since the ratio of tomato plants to squash plants is 9 : 3 = 3 : 1.
So, for every 3 tomato plants in Sunny's garden, there is 1 squash plant.
Hence, Squash plant is the right answer to fill the blank.

replace f(x) with y
y = 1/2x+4
switch x and y
x = 1/2y +4
solve for y
multiply both sides by 2
2x = y+8
subtract 8 from both sides
2x-8 = y
rewrite with y on the left side: y = 2x-8
replace y with f(x)^-1 (inverse notation)
f(x)^-1 = 2x-8
solve for f^-1(4)
replace x with 4 in the equation and solve:
2(4) -8 = 8-8 = 0
Given a mean of 24.5 and a standard deviation of 1.7, within how many standard deviations of the mean do the values 24, 23, 28, 23, 24, and 25 fall?
Answers
Given mean = 24.5 and standard deviation = 1.7
Within 1 standard deviations, x ∈ [24.5 - 1.7 , 24.5 + 1.7] or [22.8 , 26.2].
Within 2 standard deviations, x ∈ [24.5 - 2(1.7) , 24.5 + 2(1.7)] or [21.1 , 27.9].
Within 3 standard deviations, x ∈ [24.5 - 3(1.7) , 24.5 + 3(1.7)] or [19.4 , 29.6].
Given values are 24, 23, 28, 23, 24, and 25.
So {24, 23, 23, 24, 25} fall within 1 standard deviation and {28} falls within 3 standard deviations.

How would you solve 1/8 divided by 6
Answers
The required 1/8 divided by 6 is equal to 1/48.
To solve 1/8 divided by 6, we can rewrite it as a fraction. The reciprocal of 6 is 1/6, so the division problem becomes (1/8) * (1/6). To multiply fractions, we multiply the numerators together and the denominators together.
Step 1 is given as:
= (1/8) * (1/6)
Step 2(simplification) is given as:
= 1 * 1 / 8 * 6
= 1/48
Therefore, the required 1/8 divided by 6 is equal to 1/48.

T-Shirts R Us advertises shirts as shown below. mc002-1.jpg Which quantities in the advertisement represent a unit rate?
Answers
Answer:
C.) $10 per shirt
Step-by-step explanation:
have a nice day
The option C is more simplified answer for given condition, unit rate is $10.
What is unit rate?When comparing two different kinds of numbers with distinct units, a rate is a ratio that is employed. The unit rate, on the other hand, shows how many units of one quantity are equal to one unit of another. When the rate's denominator is 1, we refer to the rate as a unit rate.
Given
There are 5 shirts in the image given to us composed of 3 white shirts and 2 black shirts.
A rate with 1 as its denominator is known as a unit rate.
Option A: A ratio of 3:2 or a fraction of 3/2 is indicated by 3 white shirts and 2 white black shirts.
The denominator is not 1, hence this cannot be a unit rate.
Option B: 5 white shirts to 2 black shirts. This cannot be a unit rate because the fraction 2/5 will not have 1 as the denominator.
Choice C: $10 for each shirt. Because it represents a ratio of 10:1 or a fraction of 10/1, this rate is a unit rate. Therefore, the price of 5 shirts will be $50.
D: $50 for each shirt. Because option C has provided us with a more straightforward sum of $10, which we must accept as we are dealing with unit rates, this would not be a unit rate in this question.
Hence Option C is most suitable answer.
