A French class has students while a Spanish class has twice as many.
The Spanish class has nine more students than the French class. Find the value of f.

Answer:

$9

Step-by-step explanation:

because we would take the total which is $39 so we divide 39/ 4 1/3 = to 9 so for one crate it is going to be $9 a crate

hope this helps

Answer:

-39+5(-41)=244

Step-by-step explanation:

Consider 3 consecutive integers: (smallest) x, x+1 and x+2 (largest)

Five times the smallest means 5x

Sum of the largest and five times the smallest means x+2+5x

This sum is -244 means x+2+5x=-244

Solve this equation

x+2+5x=-244

6x+2=-244

6x=-244-2

6x=-246

x=-41

So, smallest number is -41, second is -40 and largest is -39

= -39+5(-41)=244

The price of carrots per ounce is $0.24 .

Ounce is an unit of mass in the Imperial System. It is widely used throughout the world and is one of the oldest units of measurement to still exist. The unit ounce is derived from uncia, a unit of measurement in roman times.

The ounce(abbreviated oz) is equal to approximately 28.35 grams and 16 ounces make up a pound.

Now it is given that a 2-pound bag of carrots cost $7.68 .

Therefore price per pound of carrots=$7.68÷2

Price per pound=$ 3.84 .

Now we know that 16 ounces make up a pound.

Price of carrots per ounce=  $3.84 ÷16

Price per ounce=  $ 0.24

Therefore the price of carrots per ounce is $0.24

A vertical 1-meter stick casts a shadow of 0.4 meters , then the height of the tree is 30 meters , the correct option is (c) .

We use the concept of proportions to find the height of the tree .

We know that , A vertical stick of 1 meter casts a shadow of 0.4 meters.

We have to find the height of tree which casts a shadow of 12 meter at the same time ,

Let x =  the height of the tree in meters.

So , we can write ,

⇒ 1/0.4 = x/12 ,

Simplifying this proportion:

We get ,

⇒ 0.4x = 12 ,

⇒ x = 12/0.4

⇒ x = 30

The system of equations has X(t) = [cos 2t + sin 2t, sin 2t] as a solution.

To find a planar linear system such that X(t) = [cos 2t + sin 2t, sin 2t] is a solution, we can set up a system of differential equations.

Let's define two variables x(t) and y(t) as the components of X(t):

x(t) = cos 2t + sin 2t

y(t) = sin 2t

Now, let's differentiate both equations with respect to t:

x'(t) = -2sin 2t + 2cos 2t

y'(t) = 2cos 2t

We can rewrite these equations in the form of a planar linear system:

x'(t) = -2y(t) + 2x(t)

y'(t) = 2x(t)

Therefore, the planar linear system is:

dx/dt = -2y + 2x

The maturity value of the investment would be $8,858.80.

To calculate the maturity value, we need to calculate the compound interest for each period separately and then add them together.

For the first 18 months, the interest is compounded semi-annually at a rate of 5%. Since there are two compounding periods per year, we divide the annual interest rate by 2 and calculate the interest for each period. The formula for compound interest is A = P(1 + r/n)^(nt), where A is the maturity value, P is the principal amount, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years. Plugging in the values, we get A = 8000(1 + 0.05/2)^(2*1.5) = $8,660.81.

For the next 5 months, the interest is compounded monthly at a rate of 10%. We use the same formula but adjust the values for the new interest rate and compounding frequency. Plugging in the values, we get A = 8000(1 + 0.10/12)^(12*5/12) = $8,858.80.

Therefore, the maturity value of the certificate after the specified period would be $8,858.80.

Answer:

Orange juice

Step-by-step explanation:

The bottle of apple juice costs 3 dollars for 2 liters, and the bottle of orange juice costs 3.99 dollars for 3 liters. To see which bottle has the better deal, we need to make the liters the same so we can compare them.

We can divide the 2 liters for 3 dollars ratio by 2 to get that 1 liter of apple juice costs 1.5 dollars, and we can divide the orange juice ratio by 3 to get that 1 liter of orange juice costs 1.33 dollars. We see that for 1 liter, orange juice is cheaper, so it is the better deal.

The value of the integral ∫(π/2 to π/4) csc(t) cot(t) dt is -√2 + 1.

To evaluate the integral ∫(π/2 to π/4) csc(t) cot(t) dt, we can use trigonometric identities and integration techniques.

First, let's rewrite the integrand using trigonometric identities:

Substituting these identities, the integral becomes:

∫(π/2 to π/4) (1/sin(t)) * (cos(t)/sin(t)) dt

Now, we can simplify the expression:

∫(π/2 to π/4) (cos(t)/sin²(t)) dt

To evaluate this integral, we can use the substitution method. Let u = sin(t), then du = cos(t) dt. We need to find the new limits of integration when t = π/2 and t = π/4.

When t = π/2, u = sin(π/2) = 1.

When t = π/4, u = sin(π/4) = 1/√2.

The integral becomes:

∫(1 to 1/√2) (1/u²) du

Simplifying further, we have:

∫(1 to 1/√2) u^(-2) du

Now, we can integrate:

∫(1 to 1/√2) u^(-2) du = [-u^(-1)] evaluated from 1 to 1/√2

Evaluating the definite integral, we have:

[-u^(-1)] from 1 to 1/√2 = [-(1/√2)^(-1) - (-1)^(-1)] = [-√2 - (-1)] = -√2 + 1

Therefore, the value of the integral ∫(π/2 to π/4) csc(t) cot(t) dt is -√2 + 1.

f(x) goes to -2. The end behavior of f(x) is that f(x) goes to -2 as x goes to infinity.

The end behavior of a function describes what happens to the function's values as the input (x) approaches positive or negative infinity.

For the given function f(x) = 2 - 2 as x goes to infinity, the end behavior can be determined by observing the constant term (-2) in the expression.

As x approaches positive infinity, the value of the function f(x) approaches the constant term (-2). Therefore, the correct answer is: The end behavior of f(x) is that f(x) goes to -2 as x goes to infinity.

y = k/x

where y gets smaller with larger x and larger with smaller x.

From the figure we see that the function in b, only asigns values for the points in -3, -1, 1, 3 and 4 of the x axis.

To find the range of the figure in b, we have to see what values does it take in the y axis, we notice that this values are -4, 0, 1, 4 and 5. Hence

In the case of c. we notice that the lines go on (that's is why it's represented by arrows). We note that if the lines go on, eventually they will take all the values on the x axis. Then

For the range we notice that it will take all the positive values on the y axis. then

In the case of the function a, we notice that the function assigns values to every point from -4 to 4 on the x axis. Then we can conclude that the domain is

The value of angle S is 53°

Exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of two remote interior angles.

With this theorem we can say that

7x+2 = 4x+13+19

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Since x = 10

angle S = 4x+13

angle S = 4(10) +13

= 40+13

= 53°

Therefore the measure of angle S is 53°

Total Cost = $7,200 + E. Let's revisit the question and calculate the cost of Luke's year in college using the provided information.

Given:

- Luke pays $4,800 for housing.

- Luke spends $2,400 on food.

To calculate Luke's cost of a year in college, we need to consider the additional expenses associated with his education. Let's assume the cost of tuition and other educational expenses for one year is represented by the variable "E."

By probability Luke's total cost for a year in college can be calculated as the sum of housing, food, and educational expenses:

Total Cost = Housing Cost + Food Cost + Educational Expenses

Total Cost = $4,800 + $2,400 + E

we cannot determine the exact cost of Luke's year in college. We can only express it as:

Total blocks = 6 + 2 + 4 = 12

Probability that all blocks are of same color :

P(RRR) or P(YYY) or P(GGG)

P(RRR) = 6/12 * 5/11 * 4/10 = 0.0909090

P(YYY) = 2/12 * 1/11 * 0/10 = 0

P(GGG) = 4/12 * 3/11 * 2/10 = 0.0181818
