Answer: AB=DE=6 units

$m\angle{F}=m\angle{C}=50^{\circ}$

Step-by-step explanation:

Given: ∆ABC ≅ ∆DEF

We know that if two triangles are congruent then their corresponding sides and angles are congruent. [By CPCTC]

Now, AB≅DE=6 units

Therefore, AB= 6units

EF≅BC=4 units and AC=DF

$m\angle{D}\cong m\angle{A}=30^{\circ}\\\Rightarrow\ m\angle{D}=30^{\circ}$

$m\angle{F}\cong m\angle{C}=50^{\circ}\\\Rightarrow\ m\angle{F}\cong50^{\circ}$

you are rolling a 10-sided die with sides numbered 1-10. you keep rolling the die until you roll a prime number and then stop. l

The formula for E(x) would be SUM[ X(n)P(n)] from n = 1 to n = infinity until we get the prime number

In the given problem, a 10-sided die with 1-10 numbers is rolled until we get a prime number

Prime numbers between 1-10 = 2,3,5,7 (4 prime numbers)

Non - prime numbers = 1,4,6,8,9,10( 6 non-prime number)

Let X be the number of times the die is rolled

The probability of getting a prime =

$P(Prime) = \frac{4}{10}$

Now, the value of

E(X)=∑x.P(x) [ x-> {1, infinity}]

= P(1)X(1) +P(2)X(2)+P(3)X(3)+P(4)X(4)........+ P(n)X(n)

= 1. $\frac{4}{10}$ + 2. $\frac{6}{10}$ . $\frac{4}{10}$ + 3. $\frac{6}{10}$ . $\frac{6}{10}$ $\frac{4}{10}$ + 4. $\frac{6}{10}$ . $\frac{6}{10}$ . $\frac{6}{10}$ . $\frac{4}{10}$ .......

Hence, this is the value of E(x)

Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches

area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches

10 times as many as _ hundreds is 60 hundreds or _ thousands

Vikentia [17]

10 x 6 = 60
so 10 times as many as 6 hundreds is 60 hundreds or 60 thousands

(i think this is correct, sorry if i'm wrong ((:)
