Alex777 [14]3 years ago
4 0

Answer:

95

Step-by-step explanation:

Simplify the following:

2×6 - 7 + 9^2 + 45/5

The gcd of 45 and 5 is 5, so 45/5 = (5×9)/(5×1) = 5/5×9 = 9:

2×6 - 7 + 9^2 + 9

2×6 = 12:

12 - 7 + 9^2 + 9

9^2 = 81:

12 - 7 + 81 + 9

<u>Given</u>:

The given graph represents the cost of the Kayak's rental per hour.

The coordinates are (2,30) and (3,45)

We need to determine the unit rate of renting per hour.

<u>Unit rate of renting:</u>

The unit rate of renting can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the coordinates (2,30) and (3,45), we get;

m=\frac{45-30}{3-2}

Simplifying, we get;

m=\frac{15}{1}

Dividing, we get;

m=15

Thus, the unit rate for renting a Kayak is $15 per hour.

Tomtit [17]

Answer:

360in²

Step-by-step explanation:

From the question,

L= Length = 9in

W= Width = 40in

Since, the base of rectangular prism is the same with Area of a rectangle. Then,

base of rectangular prism = ( Length × Width)

Then, Area of the base =( Lenght × Width)= ( 9 × 40)

= 360in²

Hence, area of the base of the cabinet = 360in²
