Look at the incomplete multiplication problem below.
USPshnik [31]
So I'm assuming the answers have to be the same?? if that's the case, 457×32=15904 so you would subtract 994 from 15904. That means the answer is 14,910. I hope this helped!

What is the surface area of a triangular pyramid if each face has an area of 30 mm2?
coldgirl [10]
The answer must be 120\quad m{ m }^{ 2 } since the triangular pyramid has 4 faces and each has an area of 30 m{ m }^{ 2 } we should multiply that by 4 , so :

4\cdot 30\quad m{ m }^{ 2 }=\quad 120\quad m{ m }^{ 2 }

I really need this answer to be correct
Fed [463]
It is unchanged because the same number would still be in the middle and there would still be the same amount of numbers

if
11,15,21,22,23,27,30 before 22 is the median

if
11,15,21,22,23,27,30 after 22 is still the median

The median is unchanged

A positive integer from one to six is to be chosen by casting a die. Thus the elements c of the sample space C are 1, 2, 3, 4, 5
Alex_Xolod [135]

Answer with Step-by-step explanation:

We are given that six integers 1,2,3,4,5 and 6.

We are given that sample space

C={1,2,3,4,5,6}

Probability of each element=\frac{1}{6}

We have to find that P(C_1),P(C_2),P(C_1\cap C_2) \;and\; P(C_1\cup C_2)

Total number of elements=6

C_1={1,2,3,4}

Number of elements in C_1=4

P(E)=\frac{number\;of\;favorable \;cases}{Total;number \;of\;cases}

Using the formula

P(C_1)=\frac{4}{6}=\frac{2}{3}

C_2={3,4,5,6}

Number of elements in C_2=4

P(C_2)=\frac{4}{6}=\frac{2}{3}

C_1\cap C_2={3,4}

Number of elements in (C_1\cap C_2)=2

P(C_1\cap C_2)=\frac{2}{6}=\frac{1}{3}

C_1\cup C_2={1,2,3,4,5,6}

P(C_1\cup C_2)=\frac{6}{6}=1

Alicia walks 4 miles in 1 hour and can speed walk 5 miles in 1 hour. What percent of Alicia's average speed walking rate is her
RSB [31]

Answer:

The % Alicia speed walking is 125 % of average walking

Step-by-step explanation:

Given as :

Distance cover by Alicia while walking = 4 miles

Time taken                                               = 1 hour

So, Speed of Alicia while walking = \frac{Distance}{Time}

Or,                                            S 1  =  \frac{4 miles}{1 hour}

I.e                                              S 1  =  4 mph

And

Distance cover by Alicia while speed walk  = 5 miles

Time Taken                                                      = 1 hour

So, Speed of Alicia while speed walking = \frac{Distance}{Time}

Or,                                            S 2  =  \frac{5 miles}{1 hour}

I.e                                              S 2  =  5 mph

Or,   % Rate = \frac{5}{4} ×100 = 125

Hence The % Alicia speed walking is 125 % of average walking  Answer
