Mathematics
1 answer:
Troyanec [42]3 years ago
6 0

Answer:

The value of x is 62°.

Step-by-step explanation:

It's 62° because it's a right angle (from the small box) . So you would do the given measurement (28°) and subtract that from 90°.

A machine paints 34o toy boats im 3/4 of an hour how many boats can he make per hour
leonid [27]
Here, we can set up a proportion:

34 ÷ 3/4 = ? ÷ 1
34*1 = 34
34÷3/4 = the time needed to build one toyboat

34/3/4 = 45.3333333333

45.3 repeating is not a whole number, so we need to approximate. 

45 is the closest whole number, 

So.. a machine can paint 45 toy boats per hour. 

I really hope that helped! :)

How should the decimal point in 34.05 be moved to determine the product 34.05 × 10 to the power of 6?
Ray Of Light [21]

Answer:

The decimal point should be moved Six places to the right side because there are Six zeros in 10 to the power of 6.

Step-by-step explanation:

As we have to represent the number in the form of 10^{6} we need to move the decimal Six places towards left because there are Six zeros in 10^{6} i.e. 1000000. For this purpose we will add four zeros to the left of the number.

So the number in the format mentioned in question will look like -

0.00003405 × 10^{6}.

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp. Jackie wants to manipulate the
Sauron [17]

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.

calculates three times a year, not just once a year.

f(x)= 4(4)^x

3 times a year

so x becomes 3x

f(x)= 4(1+r)^{3x}

4(4)^x=4(1+r)^{3x}

Take log on both sides

log(4)^x=log(1+r)^{3x}

log(4)^x=log(1+r)^{3x}

Use log property and move exponent before log

xlog(4)=3xlog(1+r)}

Divide both sides by x

log 4 = 3 log(1+r)

Solve for '1+r'

log 4 = log(1+r)^3

Remove log from both sides

4 = (1+r)^3

take cube root on both sides

1.584740= 1+r

1+r = 1.59

f(x)= 4(1+r)^{3x}

so equation becomes

f(x)= 4(1.59)^{3x}

1+r = 1.59

subtract 1 from both sides

So r= 59 = 59%

So growth factor is 59%

Answer is option C
