How many pounds of coffee Worth

Mathematics
1 answer:
Firdavs [7]3 years ago
5 0

Answer:

the number of pounds that should be mixed is 30 pounds

Step-by-step explanation:

The computation of the number of pounds that must be mixed is shown below:

Let us assume the number of pounds be x

Now the equation is

(x) (1) + (15) (1.60) = (x + 15) (1.20)

x + 24 = 1.20x + 18

24 - 18 = 1.20x - x

6 = 0.20x

x = 30 pounds  

Hence, the number of pounds that should be mixed is 30 pounds

The box plots below show the ages of college students in different math courses.
Slav-nsk [51]

Answer:

The correct option for this is C.) The mean and median age are more likely to be the same for the students in Math 1.

Step-by-step explanation:

i) The median age of the students is Math 1 is less than the median age of the students in Math 2.

This statement is NOT TRUE as the median age of students in Math 1 = median age of students in Math 2 = 19

ii) The mean and median age are most likely the same for both sets of data.

   This statement is NOT TRUE. The mean age of students in Math 2 should be greater than mean age of students in Math 1.

iii) The mean and median age are more likely to be the same for the students in Math 1.

  This statement is TRUE.

What is the equation of a line that is parallel to −3x+4y=4 and passes through the point (4, 0) ?
Degger [83]
First, change the given equation to slope-intercept form:

4y = 3x + 4
y = (3/4)x + 1

Because the line we are trying to write the equation for is parallel to the above line, the new line must have the same slope (3/4).

We can then substitute (4, 0) to find the y-intercept (b):

0 = (3/4) * 4 + b
0 = 3 + b
-3 = b

Our y-intercept is -3

We can now write the whole equation:

y = (3/4)x - 3

Your final answer is y = (3/4)x - 3

Hope this helps!! Let me know if you have ANY questions.

Answer:

T_{15} = 9565938

Step-by-step explanation:

Given

Sequence: 2, 6, 18, 54, 162,

Required

Determine the 15th term

The above sequence is a geometric sequence. So, first, we calculate the common ratio (r)

r = \frac{T_2}{T_1}

r = \frac{6}{2}

r = 3

The 15th term is calculated as thus:

T_n = ar^{n-1}

Where

a = 2 and n = 15

T_n = 2 * 3^{15-1}

T_n = 2 * 3^{14}

T_{15} = 2 * 4782969

T_{15} = 9565938

<em>The 15th term is 9,565,938</em>

The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27/125 of a volt and it has
alexgriva [62]

I belive this is the answer

x³ = 27/125; and

x = 3/5.

explanation:

Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us

x³.

The current voltage is 27/125; this gives us the equation

x³ = 27/125.

To solve this, take the cubed root of both sides:

∛(x³) = ∛(27/125)

x = (∛27)/(∛125)

x = (∛(3*3*3))/(∛(5*5*5))

x = 3/5
