Answer:

All figures in Group 1 appear to have at

least one square face

Step-by-step explanation:

Let us examine each statement and see whether they are true or not.

The first statement is not true. Only one of the figures (square pyramid) has at least one triangular face. It has 4 triangular faces, actually.

The second statement is not true. Only one of the figures is a rectangular prism. The remaining two are triangular pyramid and triangular prism respectively.

The third statement is not true also. Only 1 figure is a triangular prism.

The fourth statement is correct. In group 1, all the figures has at least one square face.

What is the measures of the complement and supplement of an angle that measures 35°

vazorg [7]

Answer:

Complement: 55°

Supplement: 145°

Step-by-step explanation:

Complementary angles are any two angles which sum to 90° (a right angle); supplementary angles sum to 180° (a straight angle).

35 + 55 = 90, so 55° is the complement to 35°, while 145° is the supplement, since 35 + 145 = 180.

Find the distance between each pair of points. (-5, -3) and (-5, -6)

Aloiza [94]

Answer:

• Formular for length:

$length = \sqrt{ {(x _{1} - x _{2}) }^{2} + {(y_{1} - y_{2})}^{2} }$

• from points given, x1 is -5, x2 is -5, y1 is -3 and y2 is -6:

• substitute:

$length = \sqrt{ { \{ - 5 - ( - 5) \}}^{2} + { \{ - 3 - ( - 6) \}}^{2} } \\ \\ length = \sqrt{ {0}^{2} + {3}^{2} } \\ \\ length = \sqrt{ {3}^{2} } \\ \\ { \boxed{ \boxed{ \: \: length = 3 \: units \: \: }}}$

Find the three consecutive even integers such that one half of their sum is between 15 and 21. set up and solve a compound inequ

Kay [80]

The even integers are 10,12 and 14.

Concept: An integer is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5+1/2, and √2 are not.

Let x,x+2,x+4 be the least, middle and greatest integer respectively.

According to the question,

15< x+x+2+x+4< 21

(3x+6)/2> 15 and (3x+6)/2< 21

30< 3x+6 3x+6> 42

24<3x 3x<36

8<x x>12

x=10

x+2=12

x+4=14

Hence, The even integers are 10,12 and 14.
