Jillian walked 0.5 miles before she started jogging at an average pace of 5 miles per hour. The equation d = 0.5 + 5t can be use
castortr0y [4]

Answer:

The answer is option 2.

Step-by-step explanation:

In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.

For example,

d = 0.5 + 5t

Let t = 1,

d = 0.5 + 5(1)

d = 5.5 \: miles

Let t = 5,

d = 0.5 + 5(5)

d = 25.5 \: miles

Therfore, as time increases, distance will also increase.

What is the area of this figure?
gladu [14]

Answer:

Step-by-step explanation:

A=B times H

Given: Parallelogram length = 11 cm triangle atop the parallelogram :

short leg = 7 cm : Right triangle inside the parallelogram :

long leg = 9cmArea of parallelogram =

base * heightA = 11cm * 9cmA = 99 cm²

Area of a triangle atop the parallelogram: A = ab/2A = (11cm * 7cm)/2A = 77 cm² / 2A = 38.5 cm²

Total area of the figure 99 cm² + 38.5 cm² = 137.5 cm²

A square pyramid has a base length of 4 inches. The height of each triangular face is 12 inches. What is the surface area of the
Wittaler [7]

Answer:

The surface area of the given pyramid is 112 inches^{2}.

Step-by-step explanation:

Base length of the pyramid = 4 inches

Area of the base = length^{2}

                            = 4^{2}

                            = 16

Area of its base = 16 inches^{2}

Area of one of its triangular surface = \frac{1}{2} x base x height

                                 = \frac{1}{2} x 4 x 12

                                 = 2 x 12

                                 = 24 inches^{2}

Area of all its four triangular surfaces = 4 x 24

                                                       = 96 inches^{2}

surface area of the pyramid = sum of areas of all its surfaces

                                               = 16 + 96

                                       = 112 inches^{2}

The surface area of the given pyramid is 112 inches^{2}.
