work out the area of this trapezium
6cm
10cm
8cm
17cm
Answer:
(81√15)/4 ≈ 78.43 cm²
Step-by-step explanation:
It can help to draw a diagram.
The base angle at the side of length 6 can be found using the Law of Cosines. Its opposite side is of length 8, and the two adjacent sides are of length 6 and 7. So, we have ...
8² = 6² +7² -2·6·7·cos(α)
cos(α) = (36+49-64)/(84) = 1/4
α = arccos(1/4) ≈ 75.522°
Then the height of the trapezium is ...
6·sin(75.522°) ≈ 5.80948 . . . . cm
__
The area of the trapezium is given by the formula ...
A = 1/2(b1 +b2)h
A = (1/2)(17 +10)(5.80948) . . . . cm²
A ≈ 78.43 cm²
__
Of course, sin(arccos(1/4)) = (√15)/4, so the exact formulation of the area is ...
A = (81√15)/4 cm²

22+n=-12 solve for n
Answer:
n= -34
Step-by-step explanation:
You want to get n alone so you would subtract 22 from both sides and -12 - 22 is -34
Answer:
-34
Step-by-step explanation:
22+n=-12
We move all terms to the left:
22+n-(-12)=0
We add all the numbers together, and all the variables
n+34=0
We move all terms containing n to the left, all other terms to the right
n=-34
What is the measure of angle c?
A. 30°
B. 70°
C. 110°
D. 40°
Answer:
B - 70
Step-by-step explanation:
The angles in a triangle always add up to 180.
70+40=110
180-110=70
Answer:
70 degrees
Step-by-step explanation:
All triangles have 3 angles that add up to 180 degreesHow to solve:40 + 70 + a = 180 // make equation 110 + a = 180 // add like terms- 110 - 110 // subtract 110 on both sides a = 7070 degreesHope this helps :)
Which Statment is True?
a. The data distribution is both symmetric and skewed
b. the data distribution is skewed to the left
c.the data distribution is skewed to the right
d. the data distribution is symmetric
Given Correct Statement is :- The data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. c. The data distribution is skewed to the right.
It is not possible for a data distribution to be both symmetric and skewed at the same time, as these are mutually exclusive characteristics.
A symmetric distribution is one in which the data is evenly distributed around the mean, with the left and right sides of the distribution being mirror images of each other.
A skewed distribution is one in which the data is not evenly distributed around the mean, with one tail of the distribution being longer than the other.
Based on the given options, only one statement can be true.
Option (c) states that the data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. Therefore, the correct statement is:
c. The data distribution is skewed to the right.

Answer:
[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}[/tex]
Step-by-step explanation:
Simplificación de expresiones algebraicas
Tenemos la expresión:
[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}[/tex]
La división de fracciones suele manejarse mejor utilizando la multiplicación del inverso del denominador. Es decir, para dividir la fracción a/b entre la fracción c/d se multiplica a/b*d/c para resultar (a*d)/(b*c).
Apliquemos lo anterior al problema en consideración:
[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{3m^2n^2}{5(m+n)}\cdot \frac{10(m+n)}{12m^4n}[/tex]
Multiplicamos los coeficientes en el numerador y denominador y eliminamos el factor (m+n):
[tex]=\displaystyle \frac{30m^2n^2}{60m^4n}[/tex]
La potencia 2 de la m se simplifica con la potencia 4 y la potencia 2 de la n se simplifica con la potencia 1. Igualmente se simplifica la fracción numérica dividiendo entre 30:
[tex]\boxed{\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}}[/tex]

A team of bakers can roll and form 5 dozen pretzels in 9 minutes. How many pretzels can this team form in 1 hour?
This team can form
pretzels in 1 hour.
Answer:
This team can form 400 pretzels in one hour
Step-by-step explanation:
How many pretzels in 9 minutes?
5(12)=60
Solve as proportion
60 pretzels = 9 minutes
x pretzels = 60 minutes
60(60)=9x
3600=9x
Divide both sides by 9
x= 400 pretzels
This team can form 400 pretzels in 1 hour
Answer:
this team can form 30 pretzels in 1 hour
Step-by-step explanation:
60 minutes are in a hour, and 60 divided by 9 is 6.6. So that means you would have to use 6. So 9 x 6 equals 54. Now do 5 x 6 and that would equal 30.

StartFraction StartRoot 3 EndRoot Over 2 EndFraction
StartFraction 2 StartRoot 3 EndRoot Over 3 EndFraction
Answer:
StartFraction StartRoot 3 EndRoot Over 3 EndFractionStep-by-step explanation:
Find the diagram attached.
From the right triangle XYZ:
XY is the hypotenuse
XZ and YZ are opposite and adjacent
To get value of tan(Y), we will use the SOH, CAH, TOA, trigonometry identity.
According to TOA:
Tan(Y) = XZ/ZY
First let us get XZ
Using SOH
SinY = opp/hyp = XZ/XY
SinY = XZ/4
Sin30 = XZ/4
XZ = 4sin30
XZ = 4(0.5)
XZ = 2units
Next is to get ZY:
Using Pythagoras theorem:
ZY²+XZ² = XY²
ZY² = XY²-XZ²
ZY² = 4²-2²
ZY² = 16-4
ZY² = 12
ZY = √12
ZY = √4*3
ZY = 2√3
Solve for tan(Y):
Since Tan(Y) = XZ/ZY
Tan(Y) = 2/2√3
Tan(Y) = 1/√3
Rationalize
Tan(Y) = 1/√3*√3/√3
Tan(Y) = √3/√9
Tan(Y) = √3/3
Hence the correct option is A. StartFraction StartRoot 3 EndRoot Over 3 EndFraction
