Given:
Consider the below figure attached with this question.
The length of SR is 4 m in the length of ST is 8 m.
To find:
The length of PQ in meters.
Solution:
In the below figure,
[tex]PU=SR=4\ m[/tex]
[tex]QU=ST=8\ m[/tex]
Using Pythagoras theorem in triangle PQU, we get
[tex]PQ^2=PU^2+QU^2[/tex]
[tex]PQ^2=(4)^2+(8)^2[/tex]
[tex]PQ^2=16+64[/tex]
[tex]PQ^2=80[/tex]
Taking square root on both sides, we get
[tex]PQ=\sqrt{80}[/tex]
Therefore, the correct option is A.
A. Square root of 80 m

need some help with question 20
Answer:
l = 420 cm
Step-by-step explanation:
20.
Central angle = 60°
The radius of circle, r = 7 cm
We need to find the length of the arc. We can find it as follows :
[tex]l=r\times \theta\\\\l=7\times 60\\\\l=420\ cm[/tex]
So, the length of the arc is equal to 420 cm.

Answer:
80 in^3
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base, and h is the height of the pyramid. Here, h=8 in.
__
Here, the base is a triangle. The formula for its area is ...
A = 1/2bh
where b is the base segment of the triangle, and h is the height of the triangle perpendicular to the base segment. Here, b=10 in, and h = 6 in.
The triangular base area is ...
A = 1/2(10 in)(6 in) = 30 in^2 . . . . base area "B"
__
Using the above base area and pyramid height, we find the volume of the pyramid is ...
V = 1/3(30 in^2)(8 in) = 80 in^3
The volume of the pyramid is 80 cubic inches.

the mean of 4 8 9 x and 2x is 6 calculate the value of x
Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3

Answer:
y = 5/4 x + 9
y = -5x+4
Step-by-step explanation:
a)The equation of the line in slope intercept form is expressed as y = mx+b
m is the slope
b is the intercept
Given
Slope m = 5/4
y-intercpet = 9
Substitute
y = mx+b
y = 5/4 x + 9
b) Given the coordinates (0,4) and (2, -6)
Slope m = -6-4/2-0
m = -10/2
m = -5
Since the y intercept of the line is (0, 4), hence b = 4
Get the equation
Recall
y = mx+b
y = -5x +4
This gives the required equation

Answer:
rang is 31
Step-by-step explanation:
please help!! I'm very confused
Answer:
119 in
Step-by-step explanation:
you just have to find the area of each shape individually and add them!
As we can see, we have a square base and 4 triangles. each triangle has the same area because the base is a square and they all have a height of 5. so, the area of a triangle is
[tex]a = \frac{1}{2} bh[/tex]
thus, each triangle is
[tex]a = \frac{1}{2}( 7 \times 5) = \frac{1}{2} (35) = 17.5[/tex]
since we have 4 triangles we can add this together 4 times or multiply by four.
[tex]4 \times 17.5 = 70[/tex]
now, we just need to add the area of the base. the area of a square is
[tex]a = {s}^{2} [/tex]
or
[tex]a = s \times s[/tex]
so, the area of the square is
[tex]a = {7}^{2} [/tex]
or
[tex]a = 7 \times 7[/tex]
which both equal 49.
now, we can add 49 to our sum of the area of our triangles, so
70+49= 119in
Hope this helps!

Step-by-step explanation:
The Surface are of a cylinder is 325 inches. The Lateral area is 200 in. What is radius of each base?
Answer:
The radius of each base is 4.46 inches.
Step-by-step explanation:
The surface area (SA) of a cylinder is given by:
[tex]SA = 2\pi rh + 2\pi r^{2} = 325[/tex] (1)
Where:
r: is the radius of each base
h: is the height of the cylinder
Now, the lateral area (LA) is:
[tex]LA = 2\pi rh = 200[/tex] (2)
Hence, by entering equation (2) into equation (1) we have:
[tex] SA = LA + 2\pi r^{2} [/tex]
[tex] 325 = 200 + 2\pi r^{2} [/tex]
[tex] r = \sqrt{\frac{325 - 200}{2\pi}} = 4.46 in [/tex]
Therefore, the radius of each base is 4.46 inches.
I hope it helps you!
50 POINTS FOR THIS MATH QUESTION
Answer:
B; 1
Step-by-step explanation:
Firstly, we need to find the inverse of the given function
Let us have f(x) as y
To find the inverse, we set out to make x the formula subject
Thus;
y = √(3x + 6)
square both sides
y^2 = 3x + 6
3x = y^2 - 6
x = (y^2 - 6)/3
To write the inverse, replace y by x
So we have the inverse of the function as ;
(x^2 - 6)/3
So what we have to do here is to substitute 3 for x in the inverse
We have this as;
(3^2 -6)/3
(9-6)/3
= 3/3 = 1
Answer:
1 ( option B )
Step-by-step explanation:
The given equation is ,
[tex]\implies f(x) =\sqrt{ 3x + 6 }[/tex]
Now substituting y = f(x) , we have ,
[tex]\implies y=\sqrt{ 3x + 6 }[/tex]
For finding the inverse , Interchange x and y , we have ,
[tex]\implies x =\sqrt{ 3y + 6 }[/tex]
Now solve for y , we have ,
[tex]\implies x ^2=3y + 6 \\\\\implies 3y = x^2-6 \\\\\implies y =\dfrac{x^2-6}{3} [/tex]
Now replace y with f-¹(x) , we have ,
[tex]\implies f^{-1}(x) =\dfrac{x^2-6}{3} [/tex]
Now put x = 3 , we have ,
[tex]\implies f^{-1}(3) =\dfrac{3^2-6}{3}\\\\\implies f^{-1}(3) = \dfrac{9-6}{3}\\\\\implies \underline{\underline{ f^{-1}(3) = 1 }} [/tex]

what is the perimeter of the trapezoid
Answer:
P = a + b + c + d
Step-by-step explanation:
Remember that perimeter is the measure of the outer edge of a shape, or otherwise, the sum of the measures of the sides of the trapezoid. Representing the perimeter by P, and the sides as a, b, c and d, our formula is P = a + b + c + d.

Abby earned $600 this past
summer babysitting. She decided
to put this money in a bank that
earns a 5% simple interest rate.
How many years will it take to
double her initial deposit?
do step my step equation or your answer gets reported for false info THANKSSS. I'll mark brainlist
Answer:
2 years
Step-by-step explanation:
5%× 600= $30
$30×2=$60
not sure if you will get what I mean but that's how I worked it out.
Answer:
[tex]I = \frac{PRT}{100}[/tex]
P= $600
R= 5%
[tex]I = \frac{600 \times \ 5 \times T}{100} = 30T\\\\[/tex]
A = double the deposit =2 600= $1200
[tex]A = I + P \\1200 = 30T + 600\\30T = 600\\T = 20[/tex]
The point (6, n) lies on the circle whose equation is (x − 1)2 + (y − 5)2 = 50. Find the values of n
Answer:
n = 0 or 10
Step-by-step explanation:
From the question,
Equation of the circle = (x-1)²+(y-5)² = 50 ............... Equation 1
Coordinate of the circle = (6,n)
From the question
x = 6, y = n
Substitute the value of x and y into equation 1
(6-1)²+(n-5)² = 50
5²+(n-5)² = 50
25+(n-5)² = 50
(n-5)² = 50-25
(n-5)² = 25.
Solving for n
n-5 = √(25
n-5 = ±5
Either,
n-5 = -5
n = -5+5
n = 0
or
n-5 = +5
n = 5+5
n = 10
Answer:
n = 3.16
Step-by-step explanation:
Since the point (6, n) lies on the circle then the coordinates of the point make the equation true.
Substitute x = 6 and y = n into the equation
(6 - 1)² + (n - 5)² = 50, that is, expanding using FOIL
5² + n² - 10n + 25= 50 by simplifying
25 + n² - 10n = 50 ( subtracting 50 from both sides and rearrange )
n² - 10n = 0 ← in standard form
n²=10
n = √10
The values of n is 3.16
Which expression is equivalent to
[tex]{( \sqrt[3]{{x}^{2}})}^{6} = {({x}^{ \frac{2}{3}})}^{6} = {x}^{ \frac{2}{3} \times 6 } = {x}^{2 \times 2} = {x}^{4} \\ [/tex]
So the answer is the second option which is,
[tex] {x}^{4} [/tex]
