Mathematics

This shows that about 7 and 3 pounds of each chocolate were included in the mixture.

Let the number of pounds of both chocolates be x and y.

If Enrico sold a 10-pound box of assorted chocolates, hence;

x + y = 10 ................. 1

If some of the chocolates in the box sold  for $1.75 per pound and some sold for $2.00 per pound with mixture sold for $1.90 per pound, then:

1.75x + 2x = 1.90 ................ 2

Solve equations 1 and 2 simultaneously.

x + y = 10 ................. 1 * 20

17.5x + 20x = 19 ................ 2 * 1

____________________________

20x + 20y = 200

17.5x + 20x = 19

Subtract

20x - 17.5x = 200 - 19

2.5x = 181x = 7.24

Substitute 7.24 into 1

x  + y = 10

y = 10 - 7.24

x = 2.76

This shows that about 7 and 3 pounds of each chocolate were included in the mixture.

major each of the following angles write it measures right weather it is acute ,obtuse, right angle A straight angle or a reflex
Leya [2.2K]

Answer:

i = right angle

ii = obtuse angle

iii = straight angle

iv = obtuse angle

v = acute angle

Step-by-step explanation:

an acute angle is an angle less than 90 degrees

an obtuse angle is an angle more than 90 degrees

a right angle is an angle equivalent to 90 degrees (looks like two straight lines perpendicular)

a straight angle is an angle equivalent to 180 degrees (looks like a straight line)

a reflex angle is an angle greater than 180 degrees

so, ...

i = right angle

ii = obtuse angle

iii = straight angle

iv = obtuse angle

v = acute angle

Given: Triangles ABC and DBC are isosceles, m∠BDC = 30°, and m∠ABD = 155°. Find m∠ABC, m∠BAC, and m∠DBC.
just olya [345]
∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20

aniked [119]
<span>Carl has 3 bags in total. One backpack weighs 4 kg and the rest two checking bags have the equal weight. The total weight of 3 bags is given to be 35 kg.

Let the weight of each checking bag is w kg. So we can write:

2 x (Weight of a checking bag) + Weight of Backpack = 35

Using the values, we get:

2w+ 4 = 35

Using this equation we can find the weight of each checking bag, as shown below.

2w = 31

w = 31/2

w = 15.5

Thus, the weight of each checking bag is 15.5 kg

Why would you use the measurement 8 feet 4 inches instead of 7 feet 16 inches?.
lidiya [134]

8 feet 4 inches is more precise and easier to use.

It would be weird to say 7 feet 16 inches, because there's 12 inches in a foot and your already using that measurement.


Hope this is helpful:)
