How many pounds of green tea, worth $40 a pound, should be mixed with herbal tea, worth $50 a pound, to produce 20 pounds of ble

KengaRu [80]

Answer:

840

Step-by-step explanation:

First you have to multiply 42 by 20. Because you have to find the total cost of the whole bag. Then a little guess and check you would get 16 lb of green tea and 4 lb of herbal tea. They both have to equal 20 lbs and $840. Multiply 16 by 40 then 50 by 4 then add them together you will get 840.

Hope this was helpful.

Find each measurement indicated. Round your answers to the nearest tenth. Please show your work. Part 2

uysha [10]

Answer:

4. 14.03 miles

5. 15.02 kilometers

6. 19.95 meters

Step-by-step explanation:

4. We need to use the law of sines, which states that for a triangle with angles A, B, and C and sides a, b, and c, respectively, then:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, a = 30, <A = 130, and <B = 21. So, let's plug these in:

$\frac{30}{sin130} =\frac{b}{sin21}$

b = AC = $\frac{30}{sin130}*{sin21}$ ≈ 14.03 miles

5. Here, c = 7, <C = 23, and <A = 123. We want to find BC, which is just a:

$\frac{7}{sin23} =\frac{a}{sin123}$

a = BC = $\frac{7}{sin23} *{sin123}$ ≈ 15.02 kilometers

6. Here, c = 22, <C = 88, and <B = 65. We want to find AC, which is just b:

$\frac{22}{sin88} =\frac{b}{sin65}$

b = AC = $\frac{22}{sin88} *{sin65}$ ≈ 19.95 meters

Hope this helps!
