Answer:

50,000 + 3,000 + 200 + 70 + 4

Step-by-step explanation:

Expand. Set all non-zero digits by itself:

53,274 = 50,000 + 3,000 + 200 + 70 + 4

Remember to fill in 0 for all digits. They must keep their value.

Max built a skateboarding ramp that is 16 inches high. The angle formed by the ramp and the ground is 21 . What is the length of

natali 33 [55]

Answer:

41.68 or 42 (rounded)

Step-by-step explanation:

Presuming you are working on right triangles, you can use the Soh Cah Toa theorems.

Because angle A = 21 and side a = 16 you can use Toa or $A=\frac{a}{x}$

$21=\frac{16}{x}$

Plugged into a calculator, you get 41.68 and some change.

If this is NOT a right triangle question, please let me know so that I can revise my answer.

Giving branliest pls help

Natasha2012 [34]

Answer:

${( \frac{ {2x}^{4} {y}^{4} }{ {4x}^{2} } )}^{3} \\$

open the bracket:

$= \frac{ {2x}^{(4 \times 3)} {y}^{(4 \times 3)} }{ {4x}^{(2 \times 3)} } \\$

simplify:

$= \frac{ {2x}^{12} {y}^{12} }{ {4x}^{6} } \\$

group x terms together:

$= ( \frac{ {2x}^{12} }{ {4x}^{6} } ) \times {y}^{12} \\ \\ = (\frac{ {x}^{(12 - 6)} }{2} ) \times {y}^{12} \\ \\ = \frac{ {x}^{6} }{2} \times {y}^{12}$

factorise out power 6:

${ \boxed{= \frac{ {(xy {}^{2}) }^{6} }{2} }}\\$

Suppose that 1 month before the election a random sample of 500 registered voters are surveyed. From this sample 270 indicate th

Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = $\frac{270}{500}$ = 0.54

Confidence level = 95%

now,

standard error, SE = $\sqrt{\frac{p(1-p)}{n}$

SE = $\sqrt{\frac{0.54(1-0.54)}{500}$

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]

For the function v(t) = 10(1-4^t)show why v(0)=0

IgorLugansk [536]

4^0=1
1-1=0
10*0=0
since when something is brought to the power of 0, it equals 1. Then when put into the equation the brackets = 0 therefore the whole equation equals 0
