Hello!

To find 78% of 50, you must first convert 78% to decimal form. This is done by moving the decimal two times to the left which will result in 0.78.

Then, multiply 0.78 to 50 to result in 39.

Therefore, your final answer is 39.

Hope this helps!

Hey there!!

Okay so let's start simplifying this :D

-| -2 + 9|  <---- remember that the "vertical bars" are absolute value signs

Absolute value signs will make any values within them into a positive value even if it was negative in the first place

-|  7 |   <---- first simplify what is within the absolute value signs

<u>- 7</u><u />  <----- this is your final answer!!!


I hope this helps you! ^__^

EF is the median of trapezoid ABCD.
BARSIC [14]

Answer:

Part A) x = 11

B) length of BC =  x + 12 =  x + 12 = 11 + 12 =23

length of EF =  4x - 18 =  4(11) - 18 = 44 - 18 =26

length of AD =  3x - 18 =  3(11) - 4 = 33 - 4 =29

Step-by-step explanation:

Median of trapezium is m=\frac{base1+base2}{2}

In provided figure, base1 is x+12 and base2 is 3x-4

A) solve for value of x

calculate the median m=\frac{base1+base2}{2}

4x-18=\frac{x+12+3x-4}{2}

4x-18=\frac{4x+8}{2}

4x-18=2x+4

2x-18=4

2x = 18 + 4

2x = 22

x = 11

B) To find the length of BC, AD and EF , put the value of x in equation of lines

length of BC =  x + 12 =  x + 12 = 11 + 12 =23

length of EF =  4x - 18 =  4(11) - 18 = 44 - 18 =26

length of AD =  3x - 4 =  3(11) - 4 = 33 - 4 =29

If A is a 5 by 7 matrix, what is the maximum rank that A can have?
amm1812

Answer:

5

Step-by-step explanation:

Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.

Then, if A is a matrix 5\times 7 the maximum number of pivots that can have is one by row, that is, 5.

Then the maximum rank that A can have is 5.
