<h2>Answer:</h2>

[1] Area of base = 13 × 13 = 169in².

Area of faces = 4 (1/2 × 13 × 8) = 208in².

Surface area = (169 + 208)in² = 377in².

[2] Area of base = 1/2 × 5.2 × 4.5 = 11.7in².

Area of faces = 3 (√3/4 × 5.2²) = 35.1in².

Surface area = (35.1 + 11.7)in² = 46.8in².

[3] Area of base = 7 × 10 = 70in².

Area of faces = 2(1/2 × 7 × 6) + 2(1/2 × 10 × 4.8)

= 98in².

Surface area = (70 + 98)in² = 168in².

the inequality |t-57|<7 describes the range of monthly average temperature, T, in Degrees Fahrenheit, for san Francisco, Cali

Y_Kistochka [10]

<u>Solution</u> is: $50\leq T\leq 64$ and it means, the minimum temperature is 50° Fahrenheit and the maximum temperature is 64° Fahrenheit.

<u><em>Explanation</em></u>

Given inequality is: $|T-57|\leq 7$

As this is absolute inequality, so we will get two different inequalities-- one for positive and another for negative. So.....

$T-57\leq 7\\ \\ T\leq 7+57\\ \\ T\leq 64$

and

$-(T-57)\leq 7\\ \\ -T+57\leq 7\\ \\ -T\leq 7-57\\ \\ -T\leq -50\\ \\ T\geq 50$

So, the final combined solution will be: $50\leq T\leq 64$

<em>It means that the minimum temperature for San Francisco, California is 50° Fahrenheit and the maximum temperature is 64° Fahrenheit.</em>

You are helping your dad build a rectangular dog park. The length of the dog park in feet can be represented by 8 + 2 and the wi

Goryan [66]

Answer:

74 feet and 6 feet

Step-by-step explanation:

Mentioned that

The Length of the dog park is = (8x + 2)............(i)

And,

The Width of the park is = (2x -12)..................(ii)

Perimeter = 160 feet

Now here we use the perimeter formula which is

Perimeter is

= 2 (length + width)

160 = 2 (8x + 2 + 2x - 12)

160 = 2 (10x - 10)

160 = 20x - 20

180 = 20x

x = 9

Now put the x value into the equation 1 and equaton 2

For the equaton 1, the length us

= 8x + 2

= 8(9) + 2

= 74 feet

And, the width is

= 2x - 12

= 2(9) - 12

= 18 - 12

= 6 feet

A triangular section of land is fenced off due to contamination. Two sides of the triangle are each 16 meters ( 16m) longer than

Sphinxa [80]

Answer: the shortest side is 30m

Step-by-step explanation:

Let the shortest side be a meters

If side 2 is 16m longer than the shortest side, then it is (16+a)meters.

The same goes with side 3.

Then,

a + (16+a) + (16+a) = 122m

32 + 3a = 122m

Collecting like terms together,

3a = 122 - 32

3a = 90

Divide by coefficient of a

3a/3 = 90/3

a = 30 meters

Check:

30 + (16+30) + (16+30)

30 + 46 + 46 = 112

Round 100.9052 to the nearest hundredths

Bas_tet [7]

To round 100.952 to the nearest tenth consider the hundredths’ value of 100.952, which is 5 and equal or more than 5. Therefore, the tenths value of 100.952 increases by 1 to 0.

100.952 rounded to the nearest tenth = 101.0
