Damm [24]

Answer:

He can make it with Max's audio goods

44.575 miles < 45 miles

Step-by-step explanation:

The angle of the truck driver = 180 - (60 + 69) = 51°

By using sin Rule:

40/sin51 = Max's auto goods/sin60 = Jimmy's car supply/sin69

∴ Max's auto goods = 40(sin60)/sin51 = 44.575 miles

∴ Jimmy's car supply = 40sin(69)/sin51 = 48.052 miles

∵ The truck driver can travel another 45 miles

∴ He can make it with Max's audio goods because 44.575 < 45

Hey guys ( or gals ) I have no idea what to do please help me.
shepuryov [24]

Answer:

Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.

You would have to find a GCF (greatest common factor) and multiply it out of the radical.

ex.

\sqrt{6} = 2 x 2 x 2

when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2

2\sqrt{2\\}

so \sqrt{6} would be closest to the positive 2 on the number line and 2 notches.

\sqrt{11}

is an irrational number, so it might fall into 3.3 if turned into a decimal.

Find the value of x.
earnstyle [38]

Answer:

110 degrees

Step-by-step explanation:

The sum of all the interior angles of a polygon is always equal to 180(n-2) where n is the number of sides. In this figure, there are 7 sides. This means that the sum of all the interior angles is 180(7-2) = 180 * 5 = 900.

Now, add up all the angles that you know and subtract that from 900 to find the value of x.

900 - (105 + 150 + 140 + 135 + 125 + 135) = 900 - 790 = 110 degrees

Find a formula for the nth term
vlada-n [284]

The formula for a sequence with first term = 1.7 and common difference 0.5 is: a_n = 1.2 + 0.5n

Step-by-step explanation:

The first term and common difference are used to induce a formula for the arithmetic sequence

The explicit formula for a geometric sequence is:

a_n = a_1+(n-1)d

Given

First term = a1 = 1.7

Common Difference = d = 0.5

putting the values in the formula

a_n = 1.7 + (n-1)(0.5)\\a_n = 1.7 + 0.5n-0.5\\a_n = 1.2 + 0.5n

The formula for a sequence with first term = 1.7 and common difference 0.5 is: a_n = 1.2 + 0.5n

Find the value of x.
In-s [12.5K]

Answer:

49

Step-by-step explanation:

angle QPR and angle TPS are alternate angles and their measure is equal to each other:

3x + 1 = 148 subtract 1 from both sides

3x = 147 divide both sides by 3

x = 49
