Answer:

True

Step-by-step explanation:

The n th term rule for an arithmetic sequence is

a_{n} = a + (n - 1)d

where a is the first term and d the common difference

here d = 9 - 7 = 2 and a = 7, thus

a_{n} = 7 + 2(n - 1)

If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the
fgiga [73]

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.

The perimeter of the shaded face of this cube is 12 centimeters. What is the volume of the cube in cubic centimeters?
Varvara68 [4.7K]

Answer:

1728

Step-by-step explanation: L(length) H(height) W(width)

volume = l x w x h

perimeter= L + W + L + W

perimeter = 12 + 12  + 12 + 12

volume = 12 x 12 x 12 because it' s a cube, and all sides are equal

= 1728

(i don't know if it's right though...)
