Answer:

The answer will be: C: 2t + 10

Step-by-step explanation:

You can check the answer by replacing t with any number.

Example:

I want to find the perimeter for 3 triangles. Here's how I would write the equation.

2(3) + 10 = 6 + 10 = 16

We can check by adding all the sides for three triangles.

2 + 2 + 2 + 5 + 5 = 16

Hope this helped :)

Ludmilka [50]

Well let’s see if there’s a least common multiple of 5 and 8. Since 40 is the least common mult. We will multiply 40 x .90 and 40 x 1.25 . 40x.90 is 36 while 40x1.25 is 50. It’s better to buy eight pounds for 1.25!

Find the area of the following geometric figure

romanna [79]

The area of the triangle is 90 m²

Explanation:

Given that the base of the triangle is 15 m

The altitude of the triangle is 12 m

Area of the triangle:

The area of the triangle can be determined using the formula,

$Area=\frac{1}{2}bh$

where b is the base and h is the altitude

Thus, we have,

$b=15$ and $h=12$

Substituting the values in the above formula, we get,

$Area=\frac{1}{2}(15)(12)$

Multiplying the terms, we get,

$Area=\frac{180}{2}$

Dividing, we get,

$Area=90 \ m^2$

Therefore, the area of the triangle is 90 m²

Katyanochek1 [597]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

$Box \ average =\frac{1}{6} \\\\SD = \frac{1}{6} \times \frac{5}{6} = \frac{5}{36} \approx 0.373\\\\Expected \ value= 1000 \times \frac{1}{6} \approx 166.7\\\\SE = 1000 \times 0.373 \approx 11.8\\\\$

The total number of aces is approximately 167, 12 or more. The SE is 12 out of 1000, which is 1.2 percent.

The percentage of aces is expected to be around 16.67% , or 1.2%.
