Mathematics
1 answer:
mart [117]3 years ago
6 0

Answer:

EF ≈ 1.98

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26° = \frac{opposite}{hypotenuse} = \frac{EF}{FD} = \frac{EF}{4.5 } ( multiply both sides by 4.5 )

4.5 × sin26° = EF

4.5 × 0.44 = EF , that is

EF ≈ 1.98 ( to 2 dec. places )

What happens to the value of the expression 2t/t as t decreases
anyanavicka [17]

Answer:

  it stays the same until t=0, where it is undefined

Step-by-step explanation:

2t/t = 2 . . . . when t ≠ 0

2t/t = undefined when t = 0.

The value of t can increase or decrease and the value of the ratio remains the same. The value has a "hole" at t=0, where it is undefined. Otherwise, its value is always 2.

Tan weighs 146 pounds. Minh weighs 15 pounds more than Tan. How much does Minh weigh?
dimaraw [331]

Given parameters:

Weight of Tan  = 146pounds

Unknown:

Weight of Minh = ?

Following this problem step wisely, we can derive a solvable algebraic equation;

  Let the weight of Minh  = M

In the second sentence, we see that Minh weighs 15pounds more than Tan;

    So;

              M  = 15 + Weight of Tan

Since we already know the weight of Tan,

  Weight of Minh  = 15 + 146  = 161pounds

We clearly see that Minh's weight will be 161 pounds.

Total consumption of fruit juice in a particular country in 2006 was about 1.86 billion
hram777 [196]

Answer:

Step-by-step explanation:

Kindly check explanation

Step-by-step explanation:

The population of that country in 2006 was 500 million. What was the average number of

gallons of fruit juice consumed per person in the country in 2006? Use pencil and paper. Using the per

person amount from this problem, about how many gallons would your class consume?

Total consumption in 2006 = 2.11 billion gallons (2,110,000,000)

Population of country in 2006 = 500,000,000

Average number of gallons of fruit juice consumed per person in the country in 2006:

Total consumption / total population

2,110,000,000 / 500,000,000

= 4.22 gallons per person

Number of gallons class will consume :

Assume number of students in class = 15

Hence, class consumption equals:

Average consumption per person × number of students in class :

4.22 × 15 = 63.3 gallons
