Answer:

9 hours

Step-by-step explanation:

Renting a bike costs $14 plus $6 per hour .

Keith paid $68

Hours paid for by Keith is therefore

$68 - $14

= $54

That’s amount left after renting the bike .

Hours paid for = $54/6 since an hour costs $6

= 9

Keith paid for 9 hours

Determine the length of the legs in the right triangle below.

Marysya12 [62]

Answer:

x = 14

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (14 $\sqrt{2}$ )²

2x² = 392 ( divide both sides by 2 )

x² = 196 ( take the square root of both sides )

x = $\sqrt{196}$ = 14

Thus the congruent legs are 14 cm

What is equivalent to <img src="https://tex.z-dn.net/?f=%283%5E6%293" id="TexFormula1" title="(3^6)3" alt="(3^6)3" align="absmid

kherson [118]

For this case we must indicate an expression equivalent to:

$(3 ^ 6) ^ 3$

For properties of powers we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So, the above expression can be rewritten as:

$(3 ^ 6) ^ 3 = 3^{6*3} = 3^{18}$

Thus, the resulting expression is: $3^{ 18}$

Answer:

$3^{ 18}$

I need help finding the answer , it would also be nice if you could explain it. Thank you

Hello!

First you have to find the values that you can

Angles that are across each other are the same

So the one across 80 is 80 and the angle across 70 is 70

You know 4 of the 6 angles

You add these up together

80 + 80 + 70 + 70 = 300

All the angles together make a circle

A circle has a area of 360

So you do 360 - 300 = 60

Since there are 2 angles left you do

60/2 = 30

The answer is 30

Hope this helps!

Find two consecutive positive integers such that the square of the first decreased by 17 equals 4 times the second.

Zina [86]

Answer:

The two consecutive positive integers are 7 and 8

Step-by-step explanation:

Let

x ----> the first positive integer

x+1 ----> the second consecutive positive integer

we know that

$x^{2} -17=4(x+1)$

Solve for x

$x^{2} -17=4x+4\\ \\x^{2}-4x-21=0$

Solve the quadratic equation by graphing

The solution is x=7

see the attached figure

Find the value of x+1

x+1=7+1=8

therefore

The two consecutive positive integers are 7 and 8
