The temperature at 7 P.M is 32 °F.

Fahrenheit temperature scale, scale based on 32° for the freezing point of water and 212° for the boiling point of water, the interval between the two being divided into 180 equal parts.

Given that,

Temperature at noon = 45 °F

At 7 A.M. the temperature was 17°F colder = 45-17

                                                                      = 28 °F

The temperature at 7 P.M. Was 4°F warmer than at 7 A.M

= At 7 A.M. the temperature was 17°F colder +  4°F

= 28+4

= 32 4°F

Hence, The temperature at 7 P.M is 32 °F.

The number of minutes it takes for the earth to travel one full rotation around the sun is 529, 960

A proportion can simply be described as an equation in which varying elements, or given numbers are set equal to each other.

It is seen as  a mathematical method of comparing two elements or numbers.

It is also defined as a relation that entails comparison on the basis of size or magnitude of numbers, quantities or elements.

From the information given, we have that;

The earth travels for 365. 25 days round the sun.

If 24 × 60 minutes = 1 day

Then x minutes = 365. 25 days

cross multiply, we have;

x = 24 × 60 × 365. 25

Multiply the values

x = 529, 960 minutes

Hence, the value is 529, 960 minutes

At (9, 0), the graph of the equation y = - 2/3 x + 6 intersect the x - axis.

How to create linear equation using two variables?
If an equation is written in the form ax + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Such an equation has a pair of numbers as its solution, one for x and one for y, which further equalizes the two sides of the equation. A specific point on the graph represents the solution of a linear equation in two variables, ax + by = c, where the total of these two values will equal c when the x-coordinate is multiplied by a and the y-coordinate by b. Basically, there are infinitely many solutions to a linear equation with two variables.
The linear equations can be solved using substitution method.

Given, the equation of the graph is : y = (-2/3) x + 6 -(i)
Also, the equation of x-axis is: y = 0 -(ii)
Substituting (ii) in (i), we get,
0 = (-2/3)x + 6 ⇒ (-2/3)x = -6 ⇒ (2/3)x = 6 ⇒ x = 9
Thus, the point where the graph of the equation y = - 2/3 x + 6 intersect the x - axis is (9, 0).

The change received by Dawn will be equivalent to A = 14 + (d - b).

Estimation of a price is a reasonable guess of the actual value to make calculations easier and realistic.

Given is Dawn who bought a magazine for $6 and a book for [b] dollars. She paid for the items with a $20 bill and [d] dollars bills.

The total cost of magazines and books purchased by Dawn [C]= $6 + $b

The total money paid for these items [S] = $20 + d

Amount of change received by Dawn will be [A] = S - C

A = 20 + d - (6 + b)

A = 20 + d - 6 - b

A = 14 + (d - b)

Therefore, the change received by Dawn will be equivalent to A = 14 + (d - b).

Today's expected daytime temperature:

The daytime temperature yesterday in Montana + Expected temperature drop today

But since the temperature of yesterday is negative we will use a negative sign to add the expected temperature of today. A drop in temperature will lead to a more cold temperature

Step-by-step explanation:

The percent recovery of benzoic acid is equal to 80.0 if the mass of purified benzoic acid after recrystallization is 1.611 g.

The percent recovery can be described as the amount of a product available after its production and purification.

The percent recovery of benzoic acid can be calculated by using the following formula:

percent recovery of sample = (Mass of purified sample ÷ Mass of contaminated sample) × 100

Substituting the given values of contaminated and purified benzoic acid in this equation;

percent recovery = (1.611 ÷ 2.014) × 100

percent recovery = 0.7999 × 100

percent recovery = 79.99

Rounding it to the nearest tenth;

percent recovery = 80.0

Hence the percent recovery of benzoic acid is calculated to be 80.0

Step-by-step explanation:

The equation which is best representing the height above ground, y, of the model rocket and x seconds after it reaches the maximum height is 75x + y = 2000.

The height above ground, y, of the model rocket, x seconds after it reaches its maximum height can be represent by a linear equation,

The maximum height is 2000 feet, after this the rocket starts to descend with a rate of 75 feet per second.

Let us say that when the rocket starts descending, our time is started from zero,

So, on plotting these points of graph, we can one point, (0,2000).

The rate of descend is the slope m of the graph,

m = -75 ft/s

We are taking it negative because height is decreasing with time,

We can use the point slope form of equation of line,

It says, if a line passes through (a,b) and has slope m. Then the equation of line is,

(y-b) = m(x-a)

So, our line is passing through (0,2000) and has slope -75 ft/s.

So, equation of the line is,

(y-2000) = -75(x-0)

75x + y = 2000.

This above equation of line is representing the relation between the height above ground and time of the model rocket.

Part A:

Add all the values:

Convert the oz into pounds:

1oz = 16 pounds

Divide each value by 16:

55 oz = 55/16 = 0.3125 pounds

11 oz = 11/16= 0.6875 pounds

14 oz = 14/16 = 0.875 pounds

1 pound = 1 lb

3 3/4lb= 3.75 lb

2 1/4 = 2.25 lb
