Answer:The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m<RST=(6x+12)\° -----> equation A

m<RST=78\°+(3x-12)\° -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

Answer:

18 cups of dried split peas. 16 quarts of water. 6 cups of chopped onions. 8 cups chopped celery. 16 pounds ham shank.

Step-by-step explanation:

Since that is a recipe for 8 people and 8 is a factor of 32, we can multiply the ingredient amounts by 4 (4 x 8 is 32).

2 1/4 c x 8 = 18 c.

2 qt x 8 = 16 qt.

3/4 c x 8 = 6 c.

1 c x 8 = 8 c.

2 lb x 8 = 16 lb.

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.
tia_tia [17]

Answer:

Alloy = 12.6 lbs.

Step-by-step explanation:

( 2/7 ) = ( Nickel /4.9)

Nickel = 1.4 lbs.

Ratio of Copper to Zinc:

( 9/7 ) = ( Copper /4.9)

Copper = 6.3 lbs.

Alloy = Zinc + Nickel + Copper

Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.

Alloy = 12.6 lbs.

Use the domain and range of each of the following relations to determine which is a function.
Sergeeva-Olga [200]

Answer:

a) Function

b) Not a function

c) Function

d) Not a function

Step-by-step explanation:

a) Domain = { 7,-6,2}

   Range = {5,0,3}

It is a function as every value in domain has some and unique value mapped to it in Range

b)

Domain = { 7,-6,2}

   Range = {5,0,-2,3}

It is not a function as -6 value in domain has two values mapped to it in Range

c)

Domain = { 7,2}

   Range = {-6,-7}

It is a function as every value in domain has some and unique value mapped to it in Range

d)

Domain = { 7,-6}

   Range = {5,0,3}

It is not a function as 7 value in domain has two values 3 and 5 mapped to it in Range
