Answer:
The average change of altitude per minute would simply be the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
average change of altitude = 0.55 mile / minute
Step-by-step explanation:
A garden table and bench cost $655 combined. The garden table cost $45 less than the bench. What is the cost of the bench?
Answer:
$444
Step-by-step explanation:
let the cost of the bench = x
the cost of the garden table is x + 94
so,
x + (x + 94) = 794
2x + 94 = 794
2x = 700
x = 350
The bench costs $350 and the garden table costs 350 + 94 = $444
The cost of the bench for the condition is 4350.
What are Mathematical operators?A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:
Operands: Operands are the numbers that an operator uses. The terms that are given to the operands vary according to the kind of operation.
Given the total cost of the bench and table = $655
The garden table cost $45 less than the bench,
let the cost of the bench be x
cost of table is x - 45
according to the conditions,
x + x - 45 = 655
2x = 655 + 45
x = 722/2
x = $350
Hence the cost of the bench is $350.

A. 7(−10)
B. −7(−10)
C. 7÷10
D. 7÷(−10)
Answer:
A
Step-by-step explanation:
The snake is diving deeper, meaning it is going below the surface which is represented by - numbers... time is never negative, therefore the answer can not be B.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.
Write an expression to represent the water temperature after the submarine’s final dive. Then simplify the expression to find the temperature.
Answer:
At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F
When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}
= \frac{253}{4}-\frac{11}{5}
= \frac{1265-44}{20}
= \frac{1221}{20}
= 61\frac{1}{20}°F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
The required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.
It is the relationship between sets of values. e g y=f(x),
Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as y = - 0.01x + 58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
= 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F
Thus, the required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

What is the total surface area of the right regular pyramid with a square base?
The lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Here,
Given is prism, we need to find the lateral surface and the total surface areas,
Lateral surface area = (perimeter of base) × length
Perimeter of base = 3 × 4 = 12 in
length = 8 in
The lateral surface area = 12 × 8 = 96 in²
Total surface area = (perimeter of base) × length × 2(base area)
= 96 × 2(3×4)
= 96 × 24
= 2304 in²
Hence, the lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.
