Answer:

  7 1/8 yd

Step-by-step explanation:

The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.

  P = 3·(2 3/8 yd) = 6 9/8 yd  . . . . .  9/8 = 1 1/8

  P = 7 1/8 yd

The perimeter is 7 1/8 yards.

Answer:

[tex]perimeter \: of \: the \: triangle \\ = 2 \frac{3}{8} +2\frac{3}{8} + 2 \frac{3}{8} \\ = 3 \times 2 \frac{3}{8}\\= 3 \times \frac{19}{8} \\ = \frac{57}{8} \: yd \\ = 7 \frac{1}{8} \: yd[/tex]

Answer:

3 1/4

Step-by-step explanation:

Laura walked 6 1/2 laps of a circular path in 2 hours. At that rate, she walk circular path in one hour is, 3 1/4 laps.

Rate is a ratio of change in one quantity w.r.t. change in another quantity.  The net change in one quantity  is written as, Δy and the net change in another quantity is written as, Δx.

So formula for the rate is,

m = change in one quantity/change in another quantity = Δy/Δx

Given that,

Laura walked 6 1/2 laps of a circular path in 2 hours,

Suppose, she walked at constant speed

So, we can say that

Whatever, distance she walked in 2 hour that will be double of the distance she walked in 1 hour,

Therefore, laps of the path she did  walk in one hour is (13/2)/2 =13/4

Hence, laps she walked is 3 1/4

Answer:

93 Sq.ft

Step-by-step explanation:

Formula for total surface area of a cylinder is;

TSA = 2πr² + 2πrh

In the question, we have Half cylinder, thus; TSA for half cylinder is;

TSA_½ = (2πr² + 2πrh)/2

TSA_½ = πr² + πrh

r = 3/2 = 1.5 ft

h = 5 ft

Thus;

TSA_½ = π(1.5)² + π(1.5 × 5)

TSA_½ = 30.63 Sq.ft

Surface area of rectangular prism is;

SA = 2(lw + lh + wh)

We have;

l = 5 ft

h = 2 ft

w = 3 ft

Thus;

SA = 2((5 × 3) + (5 × 2) + (2 × 3))

SA = 2(15 + 10 + 6)

SA = 62 Sq.ft

Thus, surface area of treasury is;

S.A_t = TSA_½ + SA

S.A_t = 30.63 + 62

S.A_t = 92.63 approximately 93 Sq.ft

Answer:

2.24units

Step-by-step explanation:

Let the coordinate be A(3, -5) and A'(2, -3)

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

AA' = √(2-3)²+(-3-(-5))²

AA' = √(-1)²+(-3+5))²

AA' = √1+2²

AA' =√5

AA' = 2.24 units

Note that the coordinate points are assumed

Answer:

Step-by-step explanation:

It should be $2; the cost per muffin

The cost of one muffin is $2.  

Subtraction is mathematic operation. Which is used to remove terms or objects in expression.

Given, $15 is delivery cost of muffins.

That means the if x is the cost of one muffin then

Total cost = nx + $15

,where n is the number of muffins.

Now,

for n = 1

The total cost of one muffin is :

17 = x + 15

x  = 2

Therefore, the cost of one muffin is $2.
