The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.

Step-by-step explanation:

The cost of cooling 30000 cubic foot house = $7

Cost per cubic foot = 7/30000

=$0.00023

The cost of cooling 25000 cubic foot house= $6.50

Cost per cubic foot=6.50/25000

= $0.00026

The house with 30000 cubic foot costs less to cool per cubic foot than the house with 25000 cubic foot.

Brut [27]

Answer:

Jenny gets €18.

Step-by-step explanation:

Jenny gets 3 of every Laura's 2. First you add together both numbers in the ratio. 3+2=5. Then you divide the constant, 30, by the sum, 5. 30/5=6. Then you multiply each number of the ratio by the quotient. 3 x 6=18.

1. What is the value of h? (1 point)
irinina [24]

The value of h is 11.3.

Solution:

Given data:

The triangle is a right triangle.

θ = 45° and opposite side of θ = 8

The value of sin 45° = \frac{1}{\sqrt{2} }

Using trigonometric formula,

$\sin\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}

$\sin45^\circ=\frac{{8}}{h}

$\frac{1}{\sqrt{2} } =\frac{{8}}{h}

Do cross multiplication.

h = 8\sqrt 2

h = 11.3

The value of h is 11.3.
