Please Help!!<br> It's urgent :)
Paha777 [63]

Answer:

hope this helps

Step-by-step explanation:

For a.) I would do the simplist example possible and make all 3 angles equal. So you would divide 180° degrees by 3. This gives you 60° for each angle. That is still acute.

b.) complementary angles mean they add up to 90°

If one has to be greater than 45° you can so 68° and 22°.

c.) 100 - 10,10; 20,5; 50,2; 4,25

You can choose any pair for the length and width of the ones I put above. :)

d.) angle ABC can equal 32° and angle CBD can be 10°

artcher [175]

Answer:

Right Triangle, Acute Triangle, and Obtuse Triangle

Step-by-step explanation:

I can't draw it here but the right triangle has a side of 90°.

An acute triangle has a side smaller than 90°.

An obtuse triangle has a side bigger than 90°.

The mass of a proton is approximately 1.67 x 10−24, and the mass of an electron is approximately 9.11 x 10−28. Find the approxim
nataly862011 [7]

Answer:

≈ 1833

Step-by-step explanation:

To find ratio of proton mass to electron mass, we have to divide.

The numbers are given in <em>scientific notation</em>.

Let a number be  a*10^b and another be  c*10^d, when we divide, we will follow the rule shown below:

\frac{a*10^b}{c*10^d}=(\frac{a}{c}*10^{b-d})

Now, we use the information given to find the ratio:

\frac{1.67*10^{-24}}{9.11*10^{-28}}\\=(\frac{1.67}{9.11}*10^{-24--28})\\=0.1833*10^4

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

0.1833*10^4=1833

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]

WILL GIVE BRAINLIEST ASAPP!!!!!
Mademuasel [1]

Step-by-step explanation:

Applying rules of exponents to solve the given problems;

    4^3 x 4^5 =

    5^8 ÷ 5^-2 =

     (6^3 ) ^ 4 =

For these problems, the applicable rules of exponents are;

      aᵇ x aⁿ  = aᵇ⁺ⁿ

      aᵇ  ÷ aⁿ = aᵇ⁻ⁿ

       (aᵇ)ˣ  = aᵇˣ

For the first problem; 4³ x 4⁵

     aᵇ x aⁿ  = aᵇ⁺ⁿ

      4³ x 4⁵  = 4³⁺⁵   = 4⁸

   Second problem: aᵇ  ÷ aⁿ = aᵇ⁻ⁿ

      5⁸ ÷ 5⁻²  = 5⁸⁻⁽⁻²⁾  = 5⁸⁺²  = 5¹⁰

    Third problem;  (aᵇ)ˣ  = aᵇˣ

       (6³)⁴  = 6³ˣ⁴  = 6¹²
