Answer:
Answer is m∠4=40
Step-by-step explanation:
take note that m∠6 & m∠7 are vertical angles. Vertical angles are equal to each other, therefore m∠6 is equal to m∠7.
m∠6 = m∠7 (vertical angles)
11x + 8 = 12x – 4
12x - 11x = 8 + 4
x = 12
so
m∠6 = 11x + 8
m∠6 = 11(12) + 8
m∠6 = 132 + 8
m∠6 = 140
m∠4 = 180 - m<6
m∠4 = 180 - 140
m∠4 = 40
Answer:
Step-by-step explanation:
21. The exponents cannot be added in the product having bases 12 and 11 because the bases are different. They can only be added if the bases are same.
22. a) (3¹)⁵
b) ⁵√(3²⁵)
c) (3⁵)³ ÷ (3⁵)²
23. The distance from the Earth to moon is 22⁴ miles
The distance from the Earth to Neptune is 22⁷ miles
The distance from the Earth to Neptune is greater by = 22⁷/22⁴ = 22⁷⁻⁴= 22³miles.
It is greater by three times
24. 8³. 8⁻⁵= 8³⁻⁵= 8⁻²= 1/8²= 1/64
1/64 ∠ 1
The student is not correct as 1/64 is less than 1.
6/5 is equal to 1.2, so that is a rational number.
√2 is equal to 1.570796326794
... which is a irrational number.
so ur answer would be the top right answer choice.
hope i helped:)
11.34 so have a great day
