Answer:

2.61 pounds of apples are left.

Step-by-step explanation:

Amount of green apples is 3.42 pounds and amount of red apples is 2.19 pounds.

So, the total amount of the two types apples will be:  [tex](3.42+2.19)pounds = 5.61[/tex] pounds.

Simone uses 3 pounds of apples to make a pie.

Thus, the amount of of apples left will be:  [tex](5.61-3)pounds= 2.61[/tex] pounds.

[tex]2-3(x+4)=8\qquad|\text{use distributive property}\\\\2+(-3)(x)+(-3)(4)=8\\\\2-3x-12=8\\\\-3x+(2-12)=8\\\\-3x-10=8\qquad|\text{add 10 to both sides}\\\\-3x=18\qquad|\text{divide both sides by (-3)}\\\\\boxed{x=-6}}\to\boxed{a.}[/tex]

All you have to do is simplify the equation, then isolate x to find its value:

2 - 3 ( x + 4 ) = 8

- 3 ( x + 4 ) + 2 = 8

- ( 3x + 12 ) = 2 = 8

-3x - 12 + 2 = 8

-3x - 10 = 8

-3x = 18

x = [tex]\frac{18}{-3}[/tex]

x = -6

The answer is A= -6

The equation that models the value of the coin, t years after 2016, is [tex]Y = 75(1 + 0.04)^t.[/tex] It demonstrates an exponential growth where the coin's value increases at a rate of 4% each year since 2016.

The value of the coin changes at an annual rate of 4%, which suggests an exponential growth model. The general form of an exponential growth equation is  [tex]Y = P(1 + r)^t[/tex], where Y is the future value, P is the initial (or present) value, r is the rate of interest, and t is time in years. In this case, we know the present value (P) as of 2016 is $75, the rate of interest (r) is 4% or 0.04 per year, and the time (t) indicates the number of years since 2016.

Therefore, the equation that models the value of this coin, t years after 2016, should be  [tex]Y = 75(1 + 0.04)^t.[/tex] This equation can be used to estimate the future value of an 1858 flying eagle penny given the past rate of appreciation.

The equation that models the value of the coin in dollars, t years after 2016, is A = 75(1 + 0.04)^t.

To model the value of the coin in dollars, t years after 2016, we can use the exponential growth formula:

A = P(1 + r)^t,

where A represents the final amount, P is the initial amount, r is the growth rate, and t is the number of years.

In this case, the initial amount is $75, the growth rate is 4%, and the number of years is t. So the equation would be: A = 75(1 + 0.04)^t.

Using this equation, you can calculate the value of the coin in dollars for any given year after 2016 by plugging in the number of years into the equation.

ANSWER

[tex]B=63\degree[/tex]

EXPLANATION

We want to solve the trigonometric equation;

[tex]tan^2(B)=4[/tex], where [tex]0\degree \le B \le 90\degree[/tex].

Taking square root of both sides gives,

[tex]tan(B)=\pm \sqrt{4}[/tex]

[tex]tan(B)=\pm 2[/tex]

Since B is in the first quadrant, we proceed with;

[tex]tan(B)=2[/tex], because the tangent ratio is positive in the first quadrant.

[tex]\Rightarrow B =arctan(2)[/tex]

[tex]\Rightarrow B =63.43\degree[/tex].

Correct to the nearest degree,

[tex]B =63\degree[/tex]

Answer:

For the temperature to be below 32 F, following inequality must be met,

[tex]h\geq 9.333[/tex]

Step-by-step explanation:

Let "t" be the temperature at any time.

General format of a linear equation can be given as,

y= mx + c

Where,

y ⇒ dependent variable ( in this case temperature t)

m⇒ Gradient ( the rate at which the temperature drops)

x⇒ independent variable ( hours )

c⇒ intercept ( this is the starting temperature)

Now we can substitute the given values to the above format to arrive at the equation,

[tex]t=-3h+60[/tex]

We can re-arrange the equations as ,

[tex]3h=60-t[/tex]

=[tex]h=20-\frac{t}{3}[/tex]

We can write this as an inequality when t = 32 F

[tex]h\geq 20-\frac{32}{3}[/tex]

=[tex]h\geq \frac{28}{3}[/tex]

=[tex]h\geq 9.333[/tex]

How I got this answer:

We have an open hole at 0, and shading to the left. The shading represents all the possible solutions. For example, x = -1 is a solution since it is in the blue shaded region. We can list out the numbers -7, -6, -5, -4, -3, -2, -1 as values in the solution set, but we'd be working forever since there are infinitely many numbers in this set. Also, we'd be excluding fractional and decimal values using this slow method.

As a shortcut, we can just say "any number less than 0 is a solution" which we write as x < 0 or "x is less than zero". We do not include x = 0 itself due to the open hole at 0 on the number line.

The answer is 44%

Step-by-step explanation:

To find the missing measures in a figure, utilize the properties or formulas associated with that specific shape. For example, use the Pythagorean theorem for right triangles.

To find the missing measures in each figure, you would typically use the properties of the specific geometrical shape presented.

For example, triangles have properties that are different from squares, rectangles, or circles. So, if you have a right triangle where you know the lengths of two sides, you can use the Pythagorean theorem to find the missing side.

This theorem states that a² + b² = c², where c is the length of the hypotenuse and a and b are the lengths of the other two sides. For other shapes, you may use different formulas or identities based on their properties.

2) Marika paid the remaining [tex]\$49,400[/tex] of the purchase price with her savings

3) [tex]\$49,400[/tex] represent the [tex]20\%[/tex] of the purchase price

so

[tex]0.20x=49,400[/tex]

Solve for x

Divide by [tex]0.20[/tex] both sides

[tex]0.20x/0.20=49,400/0.20[/tex]

[tex]x=247,000[/tex]

therefore

the answer is

the purchase price of the house is [tex]\$247,000[/tex]

Marika's house's total purchase price was $247,000, calculated by determining 1% of the purchase price from the known 20% and then multiplying it by 100.

To find the total purchase price of Marika's house, we can use the information that 80% of the purchase price was covered by a loan, while the remaining 20% (which is $49,400) was paid from Marika's savings. To find the full purchase price, we first find what 1% of the purchase price is by dividing the known 20% amount by 20.

1% of purchase price = $49,400 / 20

1% of purchase price = $2,470

To find the full 100% purchase price, we multiply the 1% value by 100.

Purchase price = 100 * (1% of purchase price)

Purchase price = 100 * $2,470

Purchase price = $247,000

Thus, the total purchase price of the house was $247,000.

Final answer:

In a situation where a transversal crosses parallel lines, several congruent angles and vertical angles can form, and supplementary angles are also a possibility. Complementary angles are formed only under specific conditions. The formation of obtuse angles depends on the transversal's orientation relative to the parallel lines.

When a transversal crosses parallel lines, several outcomes are possible, and we can determine which statements could be true. Let's go through the options provided:

The goal is to raise AT LEAST $180, so this automatically indicates that the amount of keychains sold with the price must be the same or more than $180.

k = number of keychains

each keychain is $2.25

2.25k ≥ 180

divide both sides by 2.25 to get the k alone

k ≥ 80

The answer is 2.25k ≥ 180, k ≥ 80

Final answer:

To find the cost of four tickets for each route, multiply the price matrix [150 160 180] by the matrix [4], giving [600 640 720] as the cost matrix for four tickets to Chicago, Boston, and Dallas respectively.

Explanation:

To find the cost of four tickets for each of the three routes from Atlanta (Chicago, Boston, and Dallas), we need to multiply the given matrix representing the prices of each route by a matrix that contains the number of tickets for each route. The cost matrix for one ticket is [150 160 180]. To calculate the cost for four tickets, we can multiply this matrix by a column matrix that has the value 4 for each route since we want to buy four tickets for each destination.

The column matrix will thus be [4] since we only have one column (for the number of tickets) and three rows (one for each destination). The multiplication process is straightforward:

[150 160 180] x [4] = [600 640 720]

So, the matrix representing the cost of four tickets to each destination is: [600 640 720].
