How do you re write 8 x 54 using distributive property?

artcher [175]

Answer: The expression, 8 x 54, may also be expressed as 8 x 50 + 8 x 4 because by factoring the 8,

8 x (50 + 4) = 8 x 54

Further, it can also be expressed as,

8 x 60 - 8 x 6

because,

8 x (60 - 6) = 8 x 54

Interpret the following sine regression model.

natita [175]

Answer:

The question is incomplete, so I will describe the sine regression model.

The function

y = 0.884 sin(0.245x - 1.093) + 0.400

correspond to the general equation:

y = a sin(bx - c) + d

where:

a = 0.884

b = 0.245

c = 1.093

d = 0.400

The amplitude of the function is computed as follows:

amplitude = |a| = 0.884

The period of the function is computed as follows:

period = 2π/|b| = 25.6456

The phase shift of the function is computed as follows:

phase shift = c/b = 4.4612 to the right (because there is a minus sign before c in the equation)

The vertical shift of the function is computed as follows:

vertical shift = d = 0.400

You have two pieces of string. One is 8 cm long. The other is 20 centimeters long. You want to cut each piece if string into sma

Minchanka [31]

ah, basically what length can you divide each string to get a certain length

factor each

8=2*2*2

therefor:

8=1*8=2*4=4*2=8*1

so you can have 1 length of string 8cm long

2 lengths of string 4cm long

4 lengths of string 2cm long

8 lengths of string 1cm long

20cm string

factor

20=1*2*2*5

so 20=1*20=2*10=4*5=5*4=10*2=20*1

you can have 1 string 20cm long

2 strings 10cm long

4 strings 5cm long

5 strings 4cm long

10 strings 2cm long

20 strings 1cm long

we need greatest common length

in 8cm stirng, we have 1,2,4,8

in 20cm string, we have 1,2,4,5,10,20

greatest common length is 4

answer is 4cm

alternately, you could have done this:

8=2*2*2

20=2*2*5

common grooup is 2*2=4 so 4 is answer

Two complementary angles have measures of s and t. if t is less than twice s, which system of linear equations can be used to de

stealth61 [152]

The required expressions are both equations 1 and 2 as shown:

$s + t = 90 ......... 1$

$t$ .... 2

Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.

According to the question, if two complementary angles have measures of s and t then:

$s + t = 90 ......... 1$

Twice of 's' is expressed as $2s$

If t is less than twice s, this can be expressed as $t$ .... 2

The required expressions are both equations 1 and 2 as shown:

$s + t = 90 ......... 1$

$t$ .... 2
