Answer:

HK=66°

Step-by-step explanation:

Based on the diagram, we know the two sides of the arcs are equal.  So we set up an equation that solves for x, then plug it back into one of the sides, and double it.

x+20=6x-45

65=5x

x=13

x+20=33

33x2=66

14 is the GCF of anumber M and 210. What are possible values of M?
Cloud [144]
<span>14 = GCF of M and 210
M = possible values

GCF = Greatest common denominator
Now, let’s start decomposing
=> 210 | 2
=> 105 | 2
=>  35 | 5
=> 7 | 7
=> 1

Thus, 2 x 3 x 5 x 7 = 210

Now let’s find the factors of 14
=> 14 | 2
=> 7 | 7
=> 1

Thus, 2 x 7 = 14

Notice that’s there’s no 14 in 210 shown factors, but the only GCF found is 7.
Thus, the value of M that we’re looking for is infinite. All numbers that has the GCF of 7 are applicable.</span>

Which of the following is equivalent to the radical expression below? 5^8*13
Bezzdna [24]

Answer:

(d) 5^{8.13} = 5^{8} * 5^{\frac{1}{10}} * 5^{\frac{3}{100}}

Step-by-step explanation:

Given

5^{8.13}

Required

Select an equivalent expression

5^{8.13}

Simplify the power

5^{8.13} = 5^{8 + 0.1 + 0.03}

Apply law of indices:

5^{8.13} = 5^{8} * 5^{0.1} * 5^{0.03}

Express decimal as fractions

5^{8.13} = 5^{8} * 5^{\frac{1}{10}} * 5^{\frac{3}{100}}
