Tea that sells for $2.00 a pound is mixed with a different tea that sells for
$5.00 a pound to produce 40 pounds of a custom blended tea that will
sell for $4.25 a pound. How many pounds of the less expensive tea
should be used in the mixture?
(1) 10
(2) 15
(3) 25
(4) 30
Pls show work
The pounds of the less expensive tea used in the mixture is 10 pounds.
The correct option is Option(1) 10.
Given:
Price of less expensive tea = $2.00
Price of expensive tea = $5.00
Price of custom-blended tea = $4.25
The total price of 40 pounds of custom blended tea = 40 × $4.25
= $170
Let the pounds of the less expensive tea used in the mixture be x pounds.
So, the pounds of expensive tea = 40-x
Now, the equation is
2x + 5(40 - x) = 170
2x + 200 - 5x = 170
3x = 30
x = 10 pounds
Therefore, there are 10 pounds of less expensive tea.

What is the equation of a line that passes through the point (2, −10) and is parallel to 14x+2y=6 ?
Enter your answer in the box.
The equation of the line passes through (2, -10) and to parallel to 14x +2y = 6 is 7x + y = 4
In the above question,
The equation of the line = 14x + 2y = 6
2y = 6 - 14x
y = [tex]- \frac{14x - 6}{2}[/tex]
y = -(7x - 3)
y = -7x + 3
The inclination of a line with respect to the horizontal is measured numerically is called as Slope
Slope of the given line = -7
The slope of a line parallel to the given line would be the same as they both are parallel to each other, hence the needed line's slope is also -7
The point through which is passes = (2, -10)
We need to find the equation of the line which passes through (2, -10) and to parallel to 14x +2y = 6
The equation of a line parallel to the given 14 x + 2 y = 6, and passing through the point (2, -10) is
[y - (-10)] = (-7)[x - 2]
y + 10 = -7x + 14
7x + y = 14 - 10
7x + y = 4
Hence, the equation of the line passes through (2, -10) and to parallel to 14x +2y = 6 is 7x + y = 4

What is cosine rule?
Cosine rule relates to the lengths of the sides of a triangle with any of its angles being a cosine angle. With the help of this rule, we can calculate the length of the side of a triangle or can find the measure of the angle between the sides.
cos x = ([tex]b^{2} +c^{2} -a^{2}[/tex])/2bc
x = 45
b = 4
c = 2
to find a
cos 45 = 4(4) +2(2) - [tex]a^{2}[/tex]/2(4)(2)

If the first two terms of an arithmetic sequence are 3 and 9, what would be the explicit equation for this sequence?
The explicit equation of the sequence is an = 3 + (n-1)*6
First term = 3
Second term = 9
A series of numbers in mathematics whose each term is always expressed as a, a+d, a+2d, or a+3d. An arithmetic progression is defined as a + (n-1)d, where a is the first term,d is the common difference of the series and n is the number of terms in the sequence
Any two continuous terms in the arithmetic sequence differ by the same number.
Arithmetic sequence is given by an = a + (n-1)d
So, the common difference = 9-3 = 6
a = 3
Substituting the values in the formula we get:

If you received $175.84 on $314 invested at a rate of 7%, for how long did you invest the principal?
The principal amount was invested for 8 Years.
In the given question, it is stated that when $314 was invested as the Principal amount, it got an Interest of $175.84 at an interest rate of 7%. We have to find out the total period of time the principal amount was kept and got interested in in order to complete the interest amount of $175.84.
To calculate the Interest, we know that the formula for Simple Interest is:
=> S.I. = (P*R*T)/100, where P = Principal amount, R = Rate of Interest, and T is the Time period. Now, putting values in the formula we get:
=> S.I. = (P*R*T)/100
=> 175.84 = (314*7*T)/100
=> T = 17584/2198
=> T = 8
Hence, we get Invested Time for 8 years.
