Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
Answer:
35 pounds of tea for 80 cents.
15 pounds of tea for 60 cents.
Step-by-step explanation:
x · 80 + y · 60 = 50 · 74
x + y = 50 · (- 60)
80x + 60y= 50 · 74
- 60x - 60y = -50 · 60
20x = 50 · (74-60) = 50 · 14
x = 50 · 14/20
35 pounds of tea for 80 cents.
y = 50 - 35 =
15 pounds of tea for 60 cents.

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 900 * 3^m, where m is the number of months after the number of visitors was measured. Evaluate the expression for m=-2. What does the value of the expression represent in the situation?
Answer:
[tex]900\times 3^m[/tex] = 100
Step-by-step explanation:
The number of visitors is modeled by the expression [tex]900\times 3^m[/tex]
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,
[tex]900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100[/tex]
At m = -2, the value of the above expression is equal to 100.
Trapezoid ABCD has vertices A(-5,9) B(-2,9) C(-8,0) D(1,0) after a translation of 2 units right and 3 units down followed by a dilation with a scale factor of 2/3. What are the vertices of trapezoid RSTU
Answer:
(-2,4), (0,4), (-4,-2) and (2,-2)
Step-by-step explanation:
Given
[tex]A = (-5,9)[/tex]
[tex]B = (-2,9)[/tex]
[tex]C = (-8,0)[/tex]
[tex]D = (1,0)[/tex]
[tex]Translation: 2\ units\ right\ \& \ 3\ units\ down[/tex]
[tex]Dilation: \frac{2}{3}[/tex]
Required
Determine the vertices of the image RSTU
When a coordinate (x,y) is translates b units right, the new coordinate is: (x + b, y)
So, translation 2 units right gives:
[tex]A = (-5,9)[/tex] ---> [tex]A' = (-5 + 2,9) = (-3,9)[/tex]
[tex]B = (-2,9)[/tex] ---> [tex]B' = (-2 + 2,9) = (0,9)[/tex]
[tex]C = (-8,0)[/tex] ---> [tex]C' = (-8 + 2,0) = (-6,0)[/tex]
[tex]D = (1,0)[/tex] --- > [tex]D' = (1 + 2,0) = (3,0)[/tex]
When a coordinate (x,y) is translates b units down, the new coordinate is: (x, y-b)
So, translation 3 units down gives:
[tex]A' = (-3,9)[/tex] ---> [tex]A" =(-3,9-3) =(-3,6)[/tex]
[tex]B' = (0,9)[/tex] --> [tex]B" =(0,9-3) =(0,6)[/tex]
[tex]C' = (-6,0)[/tex] --> [tex]C" =(-6,0-3) = (-6,-3)[/tex]
[tex]D' = (3,0)[/tex]--> [tex]D"=(3,0-3) = (3,-3)[/tex]
Lastly, dilation of 2/3 gives:
[tex]New = Old * \frac{2}{3}[/tex]
[tex]R = (-3,6) * \frac{2}{3} = (-2,4)[/tex]
[tex]S = (0,6) * \frac{2}{3} = (0,4)[/tex]
[tex]T = (-6,-3) * \frac{2}{3} = (-4,-2)[/tex]
[tex]U = (3,-3) * \frac{2}{3} = (2,-2)[/tex]
Hence, the coordinates of RSTU are: (-2,4), (0,4), (-4,-2) and (2,-2)

Jackie's commute is 15 minutes longer than Laura's. If Laura drives 12 minutes for every 17 minutes Jackie drives what are both Jackie's and Laura's drives?
Answer:
Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]51\ \text{minutes}[/tex]
Step-by-step explanation:
Laura's commute is [tex]x\ \text{minutes}[/tex]
Jackie's commute is
[tex]x+15[/tex]
Laura drives 12 minutes for every 17 minutes Jackie drives so
For every minutes Laura drives Jackie drives [tex]\dfrac{17}{12}\ \text{minutes}[/tex]
So,
[tex]\dfrac{17}{12}=\dfrac{x+15}{x}\\\Rightarrow 17x=12x+180\\\Rightarrow 5x=180\\\Rightarrow x=\dfrac{180}{5}\\\Rightarrow x=36\ \text{minutes}[/tex]
Hence, Laura drives for [tex]36\ \text{minutes}[/tex] while Jackie drives for [tex]36+15=51\ \text{minutes}[/tex].

Group of answer choices
Approximately 0.3 grams of potassium chloride can dissolve in nearly frozen water.
The maximum amount of potassium chloride that can dissolve in water at all temperatures is 0.3 grams.
The amount of potassium chloride that can dissolve in water increases by 1 gram for an increase of 0.3 degrees Celsius in temperature.
The amount of potassium chloride that can dissolve in water increases by 0.3 grams for every 1 degree Celsius increase in temperature.

If 3 centimeters is equal to 30 millimeters, how many centimeters are in 140 millimeters?
Answer:
14
Step-by-step explanation:
divide by 10
Answer:
14
Step-by-step explanation:
You have the proportion:
3 cm: 30 millimeters
divide both sides by 3
1 cm: 10 millimeters
Then, multiply both sides by 14
14cm: 140 millimeters
So 14 centimeters are in 140 millimeters

PLEASE HELP ME !!!!
Answer:
y = 17/2
Step-by-step explanation:
7y − 4 = 9y + 13 − 4y
Simplify both sides of the equation.
7y - 4 = 5y + 13
Subtract 5y from both sides.
2y - 4 = 13
Add 4 to both sides.
2y = 17
Divide both sides by 2.
y = 17/2

The expression for the given rectangle with width x and area y is[tex]y = -x^{2} +32[/tex]
it is given that
area of the rectangle = y
width of the rectangle = x
so the length of the rectangle will be = area/width = [tex]\frac{y}{x}[/tex]
perimeter = 64
What is the perimeter of a rectangle?Perimeter is the sum of all four sides of the rectangle.
we can say that,
2(length + breadth) = 64
[tex]2( \frac{y}{x} + x)=64\\\\[/tex]
[tex]\frac{y}{x} + x= 32[/tex]
[tex]\frac{y + x^{2} }{x} = 32[/tex]
[tex]y+x^{2} = 32x[/tex]
[tex]y = -x^{2} +32[/tex]
therefore, the expression for the area of the rectangle,
[tex]y = -x^{2} +32[/tex]

Bobbie Jean Byrd deposited $900 in a savings plan with her credit union. The credit union savings plan pays 6% interest compounded quarterly. If she makes no other deposits or withdrawals, how much interest will her money earn in 2 1/2 years?
Answer:
30/3 = 10
900 x 0.06 = 54
10 x 54 = 540
900 + 540 = 1440
answer prob: 1440
Based on the amount that Bobbie Byrd deposited and the interest rate as well as the period of compounding, her interest earned in 2.5 years is $144.49.
The amount is compounded quarterly so we need to convert the interest rate and the period to a quarterly basis:
6% = 6/4 quarters = 1.5%
Period = 2.5 x 4 quarters = 10 quarters
The amount after 2.5 years is:
= Amount x (1 + rate) ^ number of periods
= 900 x ( 1 + 1.5%)¹⁰
= $1,044.49
Interest is:
= Total amount after 2.5 years - Amount deposited
= 1,044.49 - 900
= $144.49

Here g is equalling -1, so substitute -1 for g in the equation. The equation is now 59 - 28(-1) = blank. Multiply 28 by -1 to get -28.
The equation is now 59 - (-28). There are two negatives in a row, so that becomes a plus sign. That makes it 59 + 28. Simply add to get 87 as your answer.
