Answer:

Step-by-step explanation:

The formula of a surface area of a rectangular prism:

$S.A.=2(lw+lh+wh)$

l - length

w - width

h - height

We have l = 15 mm, w = 3 mm, h = 4 mm. Substitute:

$S.A.=2(15\cdot3+15\cdot4+3\cdot4)=2(45+60+12)=2(117)=234$

Mrs. Cerra planted 4 ⅞ acres of wheat and 1 ⅝ acres of corn. How much more wheat did she plant than corn?

alukav5142 [94]

We can subtract the acres of corn from the acres of wheat.
$4 \frac{7}{8} - 1 \frac{5}{8} = 3 \frac{2}{8} = 3 \frac{1}{4}$
She planted 3 1/4 more acres of wheat than corn.

Polygon a b c d is shown with exterior angles. exterior angle a is 25 degrees, exterior angle b is 146 degrees, and exterior ang

Kaylis [27]

The measure of angle bcd of the polygon abcd is 40°.

Hence, option b) 40° is the correct answer.

<h3>What is a polygon?</h3>

A polygon is simply a two-dimensional a plane shape enclosed by line segments called sides.

The sum of the exterior angles of a regular polygon will always equal 360

Given that;

Exterior angle a = 25 degrees

Exterior angle b = 146 degrees

Exterior angle d = 149 degrees

Exterior angle c = ?

25° + 146° + 149° + c = 360°

320° + c = 360°

c = 360° - 320°

c = 40°

The measure of angle bcd of the polygon abcd is 40°.

Hence, option b) 40° is the correct answer.

Suppose that 2 people exercising in an enclosed room are each generating about 2.400 BTUs of body heat per

noname [10]

Answer:

0.002 BTUs per cubic foot heat is produced per hour

Step-by-step explanation:

Given:

Number of person = 2

Amount of heat produced by one person = 2.400 BTU

Dimension of the room = 20 ft x 12 ft x 10 ft

To Find:

How many BTUs per cubic foot do they produce in 1 hour = ?

Solution:

E = $\frac{ \text{(2400 Btu/ person hr}) (\text{Number of Hours}) (\text{Number of persons }) }{\text {volume of the room}}$

Substituting the values

E = $\frac{ \text{(2400 Btu/ person hr}) (1) ( 2) }{20 ft \times 12 ft \times 10 ft}$

E = $\frac{4.800}{2400}$

E = 0.002 BTU per cubic feet
