Answer:+1

Step-by-step explanation: We can substitute the blank as x which will become x-8=-7.

Now our goal is to isolate the x value so we will move over the -8 which will become +8 from crossing over the equal sign.so x=-7+8. The answer to x which is the blank space is +1.

Find the probability of drawing a 10, replacing it, and drawing an ace.

lions [1.4K]

Assuming that you're talking about a standard deck of 52 cards, there are 4 tens and 4 aces.

So, at the beginning, you have probability 4/52=1/13 to draw a ten.

You replace, and you have an identical probability to draw an ace (you still have 4 favourable cases over 52 total cases).

Multiply the two probabilities to find the answer:

$\dfrac{1}{13}\cdot\dfrac{1}{13}=\dfrac{1}{169}$

Express x% of 4 plus y% of 5 as a percentage of 11

djverab [1.8K]

X% of 4 = x*4/100 = 0.04x

y% of 5 = x*5/100 = 0.05y

x% of 4 + y% of 5 = 0.04x + 0.05y

How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %

Then make n = 0.04x + 0.05y

9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%

two concentric circular regions have radii of $1$ inch and $10$ inches. what is the area, in square inches, outside the smaller

Llana [10]

The area, in square inches, outside the smaller region, but inside the larger region is 99π

<h3>How to determine the area, in square inches, outside the smaller region, but inside the larger region?</h3>

The given parameters are:

Radius, r1 = 1 inch

Radius, r2 = 10 inches

The area, in square inches, outside the smaller region, but inside the larger region is calculated as

Area = π(R^2 - r^2)

This gives

Area = π(10^2 - 1^2)

Evaluate the difference

Area = 99π

Hence, the area, in square inches, outside the smaller region, but inside the larger region is 99π
