2 + 5 + 3 = 10 total cookies

event A picking a chocolate chip cookie = 2/10 reduced to 1/5 probability

event B picking a sugar cookie after 1 cookie was already picked = 3/9 reduced to 1/3

probability of both: 1/5 x 1/3 = 1/15 probability

Solve for r.<br> –5 ≥ 5 (r+5)
aleksandr82 [10.1K]

Answer:

-6 ≥ r

Step-by-step explanation:

–5 ≥ 5 (r+5)

Divide each side by 5

Can someone please help me I really need help please help me thank you

Hey there! :)

Answer:

SA = 144 cm².

Step-by-step explanation:

Find the surface area by calculating the areas of each of the lateral sides and bases:

In this instance, the bases are triangles, so the formula A = 1/2(bh) will be used:

Bases:

A = 1/2(bh)

A = 1/2(4·3)

A = 1/2(12)

A = 6 cm².

There are two bases, so:

6 × 2 = 12 cm²

Find the areas of the lateral sides using A = l × w:

5 × 11 = 55 cm²

4 × 11 = 44 cm²

3 × 11 = 33 cm²

Add up all of the areas:

12 + 55 + 44 + 33 = 144 cm².

Slove for x: x+1/3=1/4
lana [24]
Hey!


To solve this problem, we must subtract one over three from both sides of the equation. This will give us x on its own.

<em>Original Equation :</em>
x + \frac{1}{3} = \frac{1}{4}

<em>New Equation {Added Subtract \frac{1}{3} to Both Sides} :</em>
x + \frac{1}{3} - \frac{1}{3} = \frac{1}{4} - \frac{1}{3}

<em>Solution {New Equation Solved} :</em>
x=- \frac{1}{12}

<em>So, this means that in the equation provided</em>,  x=- \frac{1}{12}.

Hope this helps!
