Answer:

the missing side value is 6.7.

Step-by-step explanation:

so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.

Your cellular phone contract calls for a flat monthly service charge of $10.95 plus $0.12 per minute for calls within a certain

wariber [46]

Answer:

For 100 calls the monthly cost = 10.95 + 0.95(100) = $ 22.95

120 calls = 10.95 + 0.95(120) = $ 25.35

140 calls = 10.95 + 0.95(140) = $ 27.75

160 calls = 10.95 + 0.95(160) = $ 30.15

Therefore it is constant

The answer is B. Yes, the average rate of change is constant

Determine the sample space of all the possible outcomes of choosing a card number 1 to 3 or four and a blue green or yellow marb

Korolek [52]

Answer:

Step-by-step explanation:

Problem A

There are four outcomes for the cards

and three outcomes for the marbles

The total number of outcomes is 3 * 4 = 12

Problem B

Now you need 1 in three chances of getting a blue marble while any card will do. So your chances of drawing a blue marble are 1 in 3 and that is your final outcome because the cards don't affect the outcome.

fourth,sixth and thirteenth term in this sequence A(n)= 6+(n+1)(-2) help me to find and describe the explicite formula

OleMash [197]

Hello,

A(n)=6+(n+1)^(-2)=6+1/(n+1)²

$A_{4} =6+ \dfrac{1}{(4+1)^2} =6+ \dfrac{1}{25}= \dfrac{151}{25} \\

 A_{6} =6+ \dfrac{1}{(6+1)^2} =6+ \dfrac{1}{49}= \dfrac{295}{49} \\

 A_{13} =6+ \dfrac{1}{(13+1)^2} =6+ \dfrac{1}{196}= \dfrac{1177}{196} \\

Find the area of the figure.

Alona [7]

I think letter A because on area you multiply the outside but if you’re doing perimeter you do the inside.
