What is (12x - 32) in simplest form as an expression?

Answer: 109.48 U.S dollars.

Step-by-step explanation:

Given : A camera cost 115 Canadian dollars.

Also, The value of each Canadian dollar = 0.952 U.S dollars.

Then, 115 Canadian dollars=[tex]115\times0.952=109.48\text{ U.S dollars}[/tex]

Therefore, the cost of camera in  U.S dollars = 109.48

Hence, the camera costs 109.48 U.S dollars.

The equation that has an a-value of 1, a b-value of -3, and a c-value of -5 is x^2 - 3x - 5 = 0.

The student is asking for the equation of a quadratic in the form ax^2 + bx + c = 0, where the coefficients match the given values: a = 1, b = -3, and c = -5. Therefore, the equation that fits these criteria is x^2 - 3x - 5 = 0.

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).

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

[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

Set builder notation is elements of solution set of inequality is greater than 4.

The given inequality is 9t - 4 > 32.

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.

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]

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
