The length of the rectangle is 16 inches and the width is 7 inches. What is the perimeter of the figure? Use 3.14 to approximate pi.

Perimeter of the rectangle = 2L + 2W

C =2 π r
C = 2 * 3.14 * L/2

Perimeter of the figure = L + 2W + C/2

amid [387]

Answer:

a) $86.11

b) $467.33

Step-by-step explanation:

no. of gallons saved 'n' per year

n = (10000/33) - (10000/36)

n = 2500/99

Amount saved = 3.41×n = 3.41×2500/99

= $86.11

b) over 5 years:

86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )

= 86.11(5.427157431)

= $467.33

A cylinder has a radius of 7 inches and a height of 13 in. What is the volume<br> of the cylinder?
madreJ [45]

Answer:

2,637.18 in^{3}

Step-by-step explanation:

The formula for finding the volume of a cylinder is....

V = π r^{2}h

π = 3.14

Radius = 7

Height = 13

Now that we have what we need, we can substitute the numbers into the equations to get our volume

V = π r^{2}h

V = 3.14 * 7^{2} * 13

V = 3.14 * 49 * 13

V = 202.86 * 13

V = 2,637.18

The volume of the cylinder is 2,637.18 in^{3}

Hope this helped!

Pls help me with this
alexgriva [62]

Answer:

x = 1.5

Step-by-step explanation:

Given

\frac{x}{2} \geq 0.75

\frac{x}{2} < 2.5

Required

Find the value of x.

First, the inequalities need to be rewritten and merged;

if \frac{x}{2} \geq 0.75, then

0.75 \leq \frac{x}{2}

Multiply both sides by 2

2 * 0.75 \leq \frac{x}{2} * 2

1.5 \leq x

Similarly;

\frac{x}{2} < 2.5

Multiply both sides by 2

2 * \frac{x}{2} < 2.5 * 2

x < 5

Merging these results together; to give

1.5 \leq x < 5

This means that the range of values of x is from 1.5 to 4.9999....

From the question, x is the smallest rational number; from the range above (1.5 \leq x < 5), the minimum value of x is 1.5 and 1.5 is a rational number;

Hence, x  = 1.5

Given that D is the midpoint of AB and B is the midpoint of AC which statement must be true a) AD= 1/3AC
garik1379 [7]

Answer:

AD = 1/4AC

Step-by-step explanation:

Given that,

D is the the midpoint of AB

Therefore

AB = AD + DB

Since, D is the midpoint of the AB, therefore AD = DB

AB = AD + AD

AB = 2AD (i)

Similarly, B is the midpoint of AC

Hence,

AC = AB + BC

AC = AB + AB (because B is the midpoint)

AC = 2AB (ii)

By putting the value of AB from equation i to equation ii, we get

AC = 2(2AD)

AC = 4AD

AC/4 = AD

AD = 1/4AC
