Answer:

A) 7 + 4(n - 1)

Step-by-step explanation:

The explicit rule follows the form, Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference between the numbers

It says that the first term is 7, so 'a' is 7. It also says that the numbers go up by 4 (adding 4 to the previous number), hence 'd' is 4.

Sub these values into the equation:

Tn = 7 + (n - 1)*(4)

Same as: 7 + 4(n - 1)

Write each decimal as a fraction or mixed number in simplest form. 1 3/8

Mnenie [13.5K]

3/2

Step One: 1 3/8, transform the number into a improper fraction:

To have a mixed number in to a improper fraction, you need to use addition and multiplication. For 1 3/8, We first multiply the denominator (8, also know to be the bottom number of the fraction) to the whole number (1). 8x1= 8
NOTE: The original denominator (8) will be use for are improper, again playing as the denominator, we only multiply the denominator for the numerator (which is the top number of a fraction).
After multiplying, we'll add are product with the numerator (3) for the process. 8+3= 12
Now we have both numerator and denominator for 1 3/8, we can create the improper fraction. 12 as the numerator and 8 as the denominator. 12/8
We still need to simplify the number. To that, we need the biggest whole number, or rather I call it the lowest number, that can be divide both in 12 and 8.
4 can be divide by both number so: 12/4= 3 and 8/4=2
Now 3 is are simplify numerator and 2 is are simplify denominator.

Thepotemich [5.8K]

16:24 students made at least 80% on the test. The question is what is the ratio of students who scored below an 80% to the total number of students. 8:24 would be the right answer, but since it is asking for the answer in the simplest form, it would be 1:3.

Let xij = gallons of component i used in gasoline j. Assume that we have two components and two types of gasoline. There are 8,0

Mnenie [13.5K]

Answer:

option c) x₁₁ + x₁₂ = 8000

Step-by-step explanation:

Given:

xij = gallons of component i used in gasoline j

gallons of component 1 available = 8,000

demand gasoline types 1 = 11,000

demand gasoline types 2 = 14,000

Here, we have only component 1 available i.e i = 1 only

( therefore, all the options containing i = 2 gets eliminated )

thus,

component 1 will fulfill the demand of gasoline types 1 and 2 i.e j = 1 and 2

hence,

the equation satisfying the above conditions comes out as:

x₁₁ + x₁₂ = 8000

that means gallons of component 1 used in gasoline 1 and 2 and the total equals to the gallons of component 1 available i.e 8000
