Look at this prism and its net. Rectangular prism with length labeled 5 meters, width labeled 7 meters, and height labeled 12 meters. Net of the same rectangular prism with the same dimensionsn labeled. What is the surface area of this rectangular prism?

Answers

There will be three pairs of matching sides: one pair 5x7, one pair 5x12 and one pair 12x7. We can compute the are of each side (in pairs) and then add up the total:

$A_(surf)=2*(l * w)+2*(l * h)+2*(h * w)$
$A_(surf)=2*(5*7)+2*(5*12)+2*(12*7)$
$A_(surf)=2*35+2*60+2*84$
$A_(surf)=70+120+168$
$A_(surf)=358$
$A_(surf)=358m^(2)$

only 6 of the 75 trees in the park are at leat 30 feet tall. what percent of the trees are over 30 feet?

Answers

Answer:

8 %

Step-by-step explanation:

To find the percent of trees that are over 30 ft tall, take the number of trees that are over 30 ft tall over the number of tree

Percent = trees over 30 ft tall/ total number of trees

=.08

Change this to a percent by multiply by 100%

.08 * 100%

8 %

What is the name of the relationship between 1 and 4? Parallel Lines and Transversals A. corresponding angles B. alternate interior angles C. obtuse angles D. adjacent angles

Answers

The correct answer is B. alternate interior angles. Both angles are on the inside of the two parallel lines, making them interior angles, and they are alternate because they're not on the same sides of the transversal line (the line that cuts through the parallel lines). A is incorrect because corresponding angles are those that are in the same position on both parallel lines, C is incorrect because it's impossible to tell with the information given if the angles are obtuse, and D is incorrect because adjacent angles are those that are next to each other.

Answer:

The correct anwser is B hope this helps :)
