Find the value of x.

Mathematics

That square in the corner means that this is a right angle (which is 90 degrees). If you make this into an equation you will have...

66 + x + 2 = 90
combine like terms
68 + x = 90
subtract 68 from both sides
x = 22

Hope this helps :)

Answer:

8 1/3% chance (1/12)

Step-by-step explanation:

There are 24 possible rolls (4 shapes * 6 numbers). The heart has 6 numbers, so we are already at 25% chance of getting a heart. Here, it's asking for 4 or 6, so since that's 1/3 of the numbers, multiply 1/3 by 1/4 for 1/12 or 8 1/3% chance.

What is the length in feet of the base of the triangle?
worty [1.4K]

\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ A=\frac{2}{5}\\ h=\frac{6}{5} \end{cases}\implies \cfrac{2}{5}=\cfrac{1}{2}b\left( \cfrac{6}{5} \right)\implies \cfrac{2}{5}=\cfrac{6b}{10}\implies \cfrac{2}{5}=\cfrac{3b}{5} \\\\\\ 10=15b\implies \stackrel{\textit{dividing both sides by 15}}{\cfrac{10}{15}=\cfrac{15b}{15}}\implies \cfrac{10}{15}=b\implies \cfrac{2}{3}=b

In a certain game of dice, two fair dice are rolled. If the total of the faces is 4 or 10, you win. If the total is 2, 3, or 11,
goldenfox [79]
You answer should be 7/12, or aprox. 0.58 (I could be wrong)

You need to divid the number of outcomes that will satisfy your probability (anything that’s not 4,10,2,3, or 11, so there are 7 numbers left) by the total number of outcomes, (12), and that’s your answer

How to round 1,199,495 to the nearest hundredth
ollegr [7]
The next bigger hundredth is 1,199,495.01 .
The next smaller hundredth is 1,199,494.99 .
The number in the question is exactly midway in between those. Neither of them is closer to the number than the other one is. So the number is already at the nearest hundredth.
