Find the value of x.
F) 6m
G) 7.5m
H) 15m
I) 21m
Answer:
x = 6 m
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here A = 60, h = 8, a = 9 and b = x , thus
[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is
4(9 + x) = 60 ( divide both sides by 4 )
9 + x = 15 ( subtract 9 from both sides )
x = 6 m
what is the measure of one interior angle of the regular 32 gon?
Answer:
180°
Step-by-step explanation:
A polygon that has 32 sides is called a triacontadigon or a triacontakaidigon.
The angles of a triacontadigon add up to 5760°.
5760÷32=180°

Given the general form: ax + by = c How can we rewrite this general for the equation of a line, so that it is in slope intercept form? (a, b, and c are real numbers other than 0.) Hint: Substitute in values for a,b,c if you are confused) YOUR FINAL ANSWER SHOULD HAVE a,b,c in it. *
Answer:
[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex] or [tex]y = \frac{c-ax}{b}[/tex]
Step-by-step explanation:
Slope intercept form is y = mx + b, so you rewrite it to equal y.
ax + by = c
by = c - ax
y = (c - ax) / b
[tex]y = \frac{c}{b} - \frac{ax}{b}[/tex]
In the image, all the lines overlap. This proves that all the equations are equal to each other.
Fabian bought 223 feet of wood to build
wooden boxes. He estimates it will take 2
feet per box. How many boxes will Fabian be
able to build?
Answer:
111 boxes
Step-by-step explanation:
He bought 223 feet of wood
Each box will take 2 feet
To determine the total number of box he'll make from 223,
1 box = 2 feet of wood
X box = 223 feet of wood
X = (223 × 1) / 2
X = 111.5 box approximately 112 boxes
But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left
A piece of land is in the shape of a sector. Its area is 900 sq ft, while its arc length is 30 ft. What is the measure of the angle between the two radii of the sector?
Answer:
C= 2 radians.
Step-by-step explanation
Length of arc = r C where r = the radius and C is the angle in radians.
Area of the sector = 1/2 r^2 C
So we have:
30 = rC and
900 = 1/2 r^2 C
From the first equation we have r = 30/C so substituting for r:
900 = 1/2 (30/C)^2 * C
900 = 0.50 (900/C^2) * C
900 = 450/C
C= 2 radians.

Answer:
no 6^2 + 8^2 ≠ 12^2 so this is not a right triangle
Step-by-step explanation:
The Pythagorean theorem tells you if you have a right triangle
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + 8^2 = 12^2
36+64 = 144
100 = 144
This is not true so this is not a right triangle

Answer:
A. [tex]11 + 3\frac{5}{8}[/tex]
Step-by-step explanation:
Subtracting a positive number is like adding a negative number, as in you move to the left on a number line. A negative number is the opposite of the positive, so you move to the right instead, which is equivalent to adding.
Make sure there are parenthesis around the negative number, otherwise, you might be seeing one minus sign as two!
Hope this helps!

1/2 (3)(4 + 2) =
The Answer Is 9
Step-by-step explanation:
0.5(3)(6)
1.5(6)
9
Answer:
9
Step-by-step explanation:
I chose 9 because first you have to add 4+2 because it's in parenthesis and the other with parenthesis has no other numbers so 4+2 first then 4+2 is 6 then you multiply 6 by the 3 in the parenthesis because it is in the parenthesis then divide by 2 because 1/2 is basically dividing by 2

What is the exponential form of the following equation? logb3 = -8
assuming b is the underscript of log, the formula is log _b_3=-8.
the formula for log is usually log_b_x=n, and to convert it to exponential would be the same as b^n=x
just fill in the numbers, b is still b, and -8 will be the in place of n, equal to 3.
b^-8=3
Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams? y = a * (.5) ^ (1/7)
Answer:
[tex]t \approx 50.4\,min[/tex]
Step-by-step explanation:
The time constant of the element X is:
[tex]\tau = \frac{13\,min}{\ln 2}[/tex]
[tex]\tau = 18.755\,min[/tex]
The decay function has the following form:
[tex]\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }[/tex]
[tex]t = -\tau \cdot \ln \frac{m}{m_{o}}[/tex]
[tex]t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)[/tex]
[tex]t \approx 50.4\,min[/tex]

convert 20 m\s into km\hr ?
HELPPP!! PLEASEEE!
AND THANK YOUUUU
Answer: 72 km / hour
Step-by-step explanation:
Answer:
72 km/hr
Step-by-step explanation:
First, convert from meters to kilometers. 20 meters is 0.02 kilometers.
Now that you have km/s, convert 0.02 km/s into km/h by multiplying it by the number of seconds in an hour. There are 3,600 seconds in an hour. Multiply 0.02 km/s by 3,600 secs/h to get 72km/h!
