Answer:

We should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Step-by-step explanation:

The blend should,

Cost = $5

Weigh = 6 pounds.

Lets take the weight of $6 coffee as [tex]x[/tex] pounds

And lets take the weight of $3 coffee as [tex]y[/tex] pounds.

Lets write an equation for the weight of the blend,

[tex]x+y=6[/tex] <---------- 1st equation.

[tex]\frac{6x+3y}{x+y} =5[/tex]

=[tex]6x+3y=5x+5y[/tex]

=[tex]x=2y[/tex] <---------- 2nd equation

We can substitute to x in 1st equation from 2nd equation,

⇒[tex]2y+y=6[/tex]

=[tex]2y+y=6[/tex]

=[tex]3y=6[/tex]

=[tex]y=2[/tex]

We can substitute y value to 2nd equation to find x,

⇒[tex]x=2y[/tex]

=[tex]x=2*2[/tex]=[tex]x=4[/tex]

Therefore, we should use 4 pounds of $6 coffee and 2 pounds of $3 coffee for the blend.

Answer:

4 forks and 255 knives will be needed more, while 116 spoons are extra.

Step-by-step explanation:

A restaurant has 1996 forks, 1745 knives and 2116 spoons.

Owner wants to have 2000 of each utensil.

So make them equal to 2000, number of forks needed = 2000 - 1996 = 4

[Subtracted from 2000 because number of forks are less than 2000]

Number of knives needed = 2000 - 1745

                                         = 255

[Again subtracted from 2000 because number of knives are less]

Number of spoons to be donated = 2116 - 2000

                                                        = 116

[2000 is subtracted from total number of spoons because spoons are more than 2000]

Therefore, 4 forks and 255 knives will be needed more, while 116 spoons are extra.

To solve the equation 100e^0.125t=200 for t, divide by 100, apply the natural logarithm, and rearrange to find t=ln(2)/0.125, which simplifies to t=ln(16).The Correct Answer is Option. A.

The question involves solving for the variable t in the exponential equation 100e^0.125t=200.

To solve this, we need to isolate the exponent on one side. Here are the steps to find the correct value of t:

The correct answer from the given options is A. t= ln(16), as ln(2) / 0.125 = ln(16).

Remark

The 2 angles are vertically opposite and that means they are equal.

Equation

(3x - 3) = [6(x - 10)]    

Solution

Remove the brackets.

3x - 3 = 6(x - 10)

3x - 3 = 6x - 60             Subtract 3x from both sides

- 3 = 6x - 60 - 3x           Combine like terms

-3 = 3x - 60                    Add 60 to both sides

-3 + 60 = 3x

57 = 3x                           Divide by 3

57 / 3 = 3x / 3

[tex]y=4[/tex]

Step-by-step explanation:

[tex]3x+10y=13[/tex] ← Equation 1

[tex]4(-2y+x)-9x=13\\[/tex]

By simplifying the above equation we get,

[tex]-8y+=4x-9x=13[/tex] (Simplifying the brackets)

[tex]-8y-5x=13[/tex] (By subtracting [tex]-9x[/tex] from [tex]+4x[/tex]) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

[tex]15x+50y=65[/tex]

Equation 2 multiplied by 3 will give,

[tex]-24y-15x=39[/tex]

Add those together,

[tex]15x+50y-24y-15x=65+39[/tex]

[tex]26y=104[/tex] (After simplifying [tex]x[/tex] values)

Therefor [tex]y=4[/tex]

By substituting [tex]y=4[/tex] to Equation 1 we get,

[tex]3x+10*4=13[/tex][tex]3x+40=13\\3x=-27\\x=-9[/tex]

Therefor we can say,

[tex]x=-9[/tex]

[tex]y=4[/tex]

Since you didn’t include the statements, the answer is Marsha.

Why? Her slope increases more per item sold than Dreya.

[tex]\text{The slope formula is: }y=mx+b[/tex]

Marsha earns the most money per item sold because her profit margin is higher, and her earnings increase more rapidly as she sells more items compared to Dreya. Correct option is 2.

Marsha earns the most money per item sold because her profit margin per unit is higher than Dreya's. Profit margin is calculated by subtracting the cost of producing or acquiring an item from its selling price and then dividing the result by the selling price. If Marsha's profit margin per item is larger than Dreya's, it means that she earns more money for each item sold.

The statement also mentions that Marsha's slope increases more per item sold than Dreya's. This likely refers to a graphical representation where Marsha's revenue or profit line has a steeper slope than Dreya's. A steeper slope indicates that Marsha's earnings increase at a faster rate for each additional item sold, reinforcing the idea that she earns more money per item.

The average amount of rain fall is 9.61 inches

The average rainfall in Annette, Alaska is 0.31 inches per day. Over the course of an average September, the total amount of rain that falls is 9.3 inches.

To find out how much rain falls over the course of an average September, we need to know the number of days in September. Let's assume there are 30 days. Given that the average rainfall in Annette, Alaska is 0.31 inches per day, we can calculate the total rainfall by multiplying the average rainfall per day by the number of days in September: 0.31 inches/day * 30 days = 9.3 inches.

Answer: y = 1,337.00 + 177.00x

Explanation:

The total pay for the month that Whitney receives is a composition of the fixed salary, $1,337.00, and the commission, $177.00 one ach car she sells.

The commision, in turn is a function of the number of cars that she sells. So the composed function is the sum of two terms: the basic salary and the comissions.

The variables used are:

Hence, the function is: y = 1,337.00 + 177.00x

In this Decimal Point Movement question, Moving the decimal five places to the right in mathematics is a shortcut for multiplication by 105 (one hundred thousand). This uses the principle of powers of ten.

In mathematics, moving the decimal five places to the right is actually a shortcut for multiplying by 105, or 100,000. This concept utilizes the patterns in powers of ten. For instance, for any given number, we can count the zeros in the power of ten and then move the decimal point that same number of places to the right.

Illustrating with an example, let's say we have the number 5.27. If we multiply it by 105, we move the decimal five places to the right to get 527000. This aligns with the multiplication principle: when we multiply by 10, 100, 1000, and so on, each time, we are essentially incrementing the decimal place to the right.

To find the number of customers without curly hair at the salon, we multiply the total number of customers by the percentage with curly hair and subtract that from the total number of customers.

To find the number of customers who do not have curly hair, we first need to determine the number of customers who do have curly hair. We know that 25% of the customers have curly hair, which is equal to 0.25. To find this number, we multiply 0.25 by the total number of customers. So, 0.25 * 644 = 161.

Since we have the number of customers with curly hair, we can subtract this from the total number of customers to find the number without curly hair. So, 644 - 161 = 483 customers do not have curly hair at Terrific Tresses hair salon.

Answer:

Step-by-step explanation:

To solve this problem we need to apply the rule of three.

If one serving has 95 calories, then how much calories would have 2.5 servings?

[tex]2.5 \ servings \ \frac{95 \ calories}{1 \ serving}=237.5 \  calories[/tex]

Therefore, 2.5 servings have 237.5 calories.

(1/36)^n = 216

Rewrite 36 as 6^2

(1/6^2) ^n = 216

Since 36 is in the denominator, the exponent is negative

(6^-2) ^n = 216

Rewrite 216 as 6^3

(6^-2)^n = 6^3

We know that a^b^c = a^(b*c) so

6^(-2n) = 6^3

Since the bases are the same, the exponents are the same

-2n = 3

Solving for n

n =-3/2

n = -1.5

Final answer:

The value of n for which [tex](1/36)^n[/tex] equals 216 is -3/2. This is found by expressing both sides of the equation with the common base of 6 and equating the exponents, then solving for n.

Explanation:

To find the value of n for which [tex](1/36)^n[/tex]= 216, first we express 216 as a power of 6, since 36 is a power of 6 (36 = [tex]6^2[/tex]): 216 = [tex]6^3[/tex]. We can then rewrite the equation using this equivalent expression of 216 and the knowledge that 1/36 is [tex]6^-2[/tex]:

[tex](6^-2)^n = 6^3[/tex]

Using the power of a power rule, this simplifies to:

[tex]6^(-2n) = 6^3[/tex]

Since the bases are the same, the exponents must be equal:

-2n = 3

Dividing both sides by -2 to solve for n, we get:

n = -3/2
