N76 [4]3 years ago
4 0

Looking at the question, we can see we have 5 different numbers that can go in any order.

<u>5</u> * <u>4</u> * <u>3</u>

The above is basically saying there are 5 different numbers that can be multiplied by 4 other numbers. Those 2 can be multiplied by 3 different ones, leaving us with a 3 digit positive integer.

5 * 4* 3 = 60

Schach [20]
3(n+5) < 3/4(n)

The three is multiplied by n+5. Whenever you see "is equal to/greater/less than," that is where you put your =, >, or < signs. Your variable, "n" represents the number. So three-fourths of the number is the same as multiplying the number by three-fourths.

Answer:

y = 72.5 cm

Step-by-step explanation:

We know that tan theta = opposite/ adjacent

  tan 30 = x/y

 tan 30 =36.25/y

Multiply each side by y

y tan 30 = 36.25y/y

y tan 30 = 26.25

Divide each side by tan 30

y tan 30 / tan 30 = 36.25/tan 30

y = 36.25/ tan 30

y =72.5

As a large truck fills its gas tank, the volume of gas, in gallons, can be modeled with the linear function v = 4.8m + 8.2, wher
jek_recluse [69]

Step-by-step explanation:

Step one:

given data

we are told that the expression is

v = 4.8m + 8.2

where  v is the volume of gas and

            m is the number of minutes it has been filling.

Step two:

Required

<em>Asumming the volume is in Liters</em>

the interpretation of the terms in the expression for the volume

4.8 means that  for every minute 4.8L of gas enters the gas tank

hence the rate of filling is 4.8L/min

8.2 means that there is 8.2L of gas already in the tank before the filling started.
