Answer:

180 square inches

Step-by-step explanation:

Area, A is given by A=0.5bh where b is base and h is height. Since both of these dimensions are provided then we substitute the given figures into the formula. Substituting 12 inches for base, b and 30 inches for height, h then the area will be equivalent to

A=0.5*12*30=180 square inches.

Therefore, the area of the described triangle is 180 square inches.

Which models show 40%? Check all that apply. A model with 4 shaded sections and 6 unshaded sections. A model with 40 shaded sect

Amanda [17]

Answer:

A model with 4 shaded sections and 6 unshaded sections.

A model with 40 shaded sections and 60 unshaded sections.

Step-by-step explanation:

Required:

Which models shows 40%

(a) 4 shaded and 6 unshaded

First, we calculate the total sections

$Total = 4 + 6$

$Total = 10$

The percentage of the shaded section is:

$Shaded = \frac{4}{10} * 100\%$

$Shaded = 0.4 * 100\%$

$Shaded = 40\%$

(b) 40 shaded and 60 unshaded

First, we calculate the total sections

$Total = 40 + 60$

$Total = 100$

The percentage of the shaded section is:

$Shaded = \frac{40}{100} * 100\%$

$Shaded = 0.4 * 100\%$

$Shaded = 40\%$

(c) 2 shaded and 8 unshaded

First, we calculate the total sections

$Total = 2 + 8$

$Total = 10$

The percentage of the shaded section is:

$Shaded = \frac{2}{10} * 100\%$

$Shaded = 0.2 * 100\%$

$Shaded = 20\%$

Hence, (a) and (b) shows 40%

Answer:

∠U = 40°

Step-by-step explanation:

in order to find the missing angle of U we need to know the two other angles.

We know that ∠T is 65° and we know that ∠TSF is 105°. Because ∠TSF is an exterior angle, we can subtract 180 to get the interior angle. This would mean that ∠S is 75°.

Using this we can add 65 to 75 then subtract the total from 180 to get ∠U.

This would mean that ∠U is 40°
