Suppose there is a 1.1 degrees Fahrenheit drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 59.7 degrees Fahrenheit, what will be the temperature at the altitude of 11000 ft?
Answer:
47.6 Degree Fahrenheit
Step-by-step explanation:
Given:
The Airplane is on the ground level at a temperature 59.7 Fahrenheit. Every 1,000 feet there will be drop in temperature which is 1.1 degrees Fahrenheit.
Initial Temp = 59.7 Fahrenheit
Distance Covered = 11,000 Ft
Explanation:
This means the Ground level is zero feet as the Airplane stands there.
Later, it climbs into the sky with 11,000 altitude.
That is [tex]11 * 1000[/tex]
For every 1,000 there is decrease in temperature of 1.1 degree Fahrenheit
Therefore, 11 times the temperature will decrease
That is [tex]11 * 1.1[/tex]
12.1 Degree temperature will drop at 11,000 feet
Therefore
Temperature at 11,000 feet will be [tex]59.7 - 12.1[/tex]
47.6 Degree Fahrenheit
Answer:47.6
Step-by-step explanation:the airplane is on ground level at a temperature of 59.7 f every 1000 deggres will drop

The explanation provides a step-by-step process to determine the minimum trips required for the miners to cross the river.
To determine the minimum number of trips required for the miners to cross the river, we need to carefully consider the constraints given.
First, A and B can cross together because the maximum combined weight of their cargoes is 90 kg (40 + 50) which is less than 100 kg.
Then, A returns alone, carrying B's cargo, leaving B and C on the other side. B and C cross together as the combined weight of their cargoes is 40 kg (20 + 20) which is less than 100 kg.
Finally, B returns and takes A's cargo, crossing with C's cargo. In total, the minimum number of trips needed is 9 (Option A).

Multiply.
[tex](3.5 \cdot 10^{-5})(3 \cdot 10^{-10})[/tex]
To multiply it we apply exponential property
First we multiply the number 3.5 and 3
3.5 times 3 is 10.5
Now we apply exponential property to multiply the exponents
[tex]a^m \cdot a^n = a^{m+n}[/tex]
[tex]10^{-5} \cdot 10^{-10}= a^{-5-10}=10^{-15}[/tex]
[tex](3.5 \cdot 10^{-5})(3 \cdot 10^{-10})[/tex]
[tex]10.5 \cdot 10^{-15}[/tex]
To get the expression in scientific notation we move the decimal point 1 units to the left

A neighbor pays you and two friends $90 to paint her garage. You divide the money three ways in the ratio 2:3:5.
Answer:
First friend gets $18, second friend gets $27, third friend gets $45
Step-by-step explanation:
The ratio means that each person get different quantity.
The total amount must be divided between the 3 persons in the following way
First person gets 2 parts
Second person gets 3 parts
Third person gets 5 parts
If we add all parts, we get 10 parts,if we divide the total payment we get how much is each part, in this case $90 / 10 , so $9
Each part is $9. To get how much will get each friend , we multiple the quantity of parts by the value of them.
First person gets 2 parts, that means $18
Second person gets 3 parts that means $27
Third person gets 5 parts that means $45

The math team sold 42 hamburger meals and 15 ribs meals at the pep rally for a total of $243. At the game that night, they sold 36 hamburger meals and 30 ribs meals for a total of $294. What is the cost of 1 rib meal?
Answer:
$5.
Step-by-step explanation:
Let h be the cost of each hamburger meal and r be the cost of each rib meal.
We have been given that the math team math team sold 42 hamburger meals and 15 ribs meals at the pep rally for a total of $243. We can represent this information in an equation as:
[tex]42h+15r=243...(1)[/tex]
We are also told that math team also sold 36 hamburger meals and 30 ribs meals for a total of $294. We can represent this information in an equation as:
[tex]36h+30r=294...(2)[/tex]
We will use substitution method to solve our system of equations. From equation (1) we will get,
[tex]h=\frac{243-15r}{42}[/tex]
Substituting this value in equation (2) we will get,
[tex]36(\frac{243-15r}{42})+30r=294[/tex]
[tex]6(\frac{243-15r}{7})+30r=294[/tex]
[tex]\frac{1458-90r}{7}+30r=294[/tex]
Now let us have a common denominator.
[tex]\frac{1458-90r}{7}+\frac{7*30r}{7}=294[/tex]
[tex]\frac{1458-90r}{7}+\frac{210r}{7}=294[/tex]
[tex]\frac{1458-90r+210r}{7}=294[/tex]
[tex]\frac{1458+120r}{7}=294[/tex]
[tex]\frac{1458+120r}{7}\times 7=294\times 7[/tex]
[tex]1458+120r=2058[/tex]
[tex]1458-1458+120r=2058-1458[/tex]
[tex]120r=600[/tex]
[tex]\frac{120r}{120}=\frac{600}{120}[/tex]
[tex]r=5[/tex]
Therefore, the cost of 1 rib meal is $5.

Write the solution to the inequality in set builder notation.
9t - 4 > 32
Set builder notation is elements of solution set of inequality is greater than 4.
The given inequality is 9t - 4 > 32.
What is set builder notation?A set-builder notation describes the elements of a set instead of listing the elements. For example, the set {5, 6, 7, 8, 9} lists the elements. We read the set {x is a counting number between 4 and 10} as the set of all x such that x is a number greater than 4 and less than 10.
The solution to the inequality 9t - 4 > 32 can be solved as follows:
Add 4 on both the sides of the inequality.
That is, 9t - 4 + 4 > 32 + 4
⇒ 9t > 36
Divide 9 on both the sides of the inequality.
That is, 9t ÷ 9 > 36 ÷ 9
⇒ t > 4
Set builder notation is elements of solution set is greater than 4.
Therefore, set builder notation is elements of solution set of inequality is greater than 4.
