Simplify and solve for d. 1/6d+2/3=1/4(d-2)

Mathematics
1 answer:
Dvinal [7]4 years ago
3 0
1/6d + 2/3 = 1/4(d - 2)
1/6d + 2/3 = 1/4d -1/2
2/12d + 4/6 = 3/12d -3/6
4/6 = 1/12d - 3/6
7/6 = 1/12d
7/6 x 12/1 = d
84/6 = d
14 = d

So d = 14.

Hope I helped.. ^^

What is the measure of an interior angle of a regular polygon iwth 15 sides
KiRa [710]
To find the measure of an interior angle of any regular polygon, we use the formula:

180 * (n-2)  / n, 

where n is the number of sides in the regular polygon.

Therefore, if there are 15 sides in the regular polygon, your answer would be 

180 * (15-2) / 15, 

or when simplified,

180 * 13 / 15

2340 / 15

156 degrees.

Thus, the measure of an interior angle of a regular polygon with 15 sides is 156 degrees.

It takes Max 5.5 minutes to do 60 pull ups which includes a break in between. It takes him 8 minutes to do 120 pull ups which in
Ivahew [28]

Answer: 648 pull-ups

Step-by-step explanation:

Given

Max take 5.5 minutes to do 60 Pull-ups with a break in between

Similarly, it took 8 minutes for 120 pull-ups

Suppose the time taken for a single pull-up and break is x and y  minutes

So, it can be written

\Rightarrow 60x+y=5.5\quad \ldots(i)\\\Rightarrow 120x+y=8\quad \ldots(ii)\\\\\text{Solve (i) and (ii) we get}\\\\x=\dfrac{2.5}{60}\ min \ or\ \ 2.5\ s\\\\y=3\ min

Now, suppose max perform at this rate, and the total pull-ups are P in 30 minutes

\therefore P\times \dfrac{2.5}{60}+3=30\\\\\Rightarrow P\times \dfrac{2.5}{60}=27\\\\\Rightarrow P=648\ \text{Pull-ups}

Triangle QRS has been translated to create triangle Q'R'S'. RS= R'S' = 10 units, angles Q and Q' are both 90 degrees. Which post
RSB [31]

The <em><u>correct answer</u></em> is:

HL

Explanation:

These will both be right triangles, as angle Q and angle Q' are both 90 degrees.

Since Q and Q' are the right angles, this means that RS and R'S' are the hypotenuses of the two right triangles.

Since Q'R'S' was created by translating QRS, a corresponding leg of both triangles will be congruent; this gives us hypotenuse-leg, or HL.
