23-6=17
17-7=10
The third side is 10m

Since there are 3 sides of a triangle, and you already have two sides, just subtract the sun of the two sides from the total. You have 6 and 7 meters. Combine those into 13, then subtract if from 23. You get 10 meters. So, the mystery side would be 10m.

Write a function rule to represent the sequence 0.3,0.9,1.5,2.1<br> PLease help

liraira [26]

The rule for sequence is:

$a_n=0.3+(n-1)(0.6)$

Step-by-step explanation:

To write the function rule, we have to check first whether it is an arithmetic sequence or geometric sequence

We have to find the common difference first. Common difference is the difference between two consecutive terms of a arithmetic sequence.

So,

Here

$a_1=0.3\\a_2=0.9\\a_3=1.5\\a_4=2.1\\d=a_2-a_1=0.9-0.3=0.6\\a_3-a_2=1.5-0.9=0.6$

The common difference is same so the sequence is an arithmetic sequence.

The explicit formula for an arithmetic sequence is:

$a_n=a_1+(n-1)d\\$

Putting the values of d and a_1 we get,

$a_n=0.3+(n-1)(0.6)$

Hence,

The rule for sequence is:

$a_n=0.3+(n-1)(0.6)$

158 divided by 37 I don’t get it what is the answer

Salsk061 [2.6K]

Answer:

4.2702702703

4 Remainder 10

Step-by-step explanation:

158 divided by 37 = 4.270

The result of 158/37 is a non-terminating, repeating decimal.

The repeating pattern above, 270, is called repetend, and denoted overlined with a vinculum.

This notation in parentheses is also common: 158/37 = 4.(270): However, in daily use it’s likely you come across the reptend indicated as ellipsis: 158 / 37 = 4.270… .

158 divided by 37 in decimal = 4.270

158 divided by 37 in fraction = 158/37

158 divided by 37 in percentage = 427.02702703%

Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 158 and 37, of course.

Repetends, if any, are denoted in ().

The conversion is done automatically once the nominator, e.g. 158, and the denominator, e.g. 37, have been inserted.

Every 5 1/2 cups of flour weighs 1 9/16 pounds. use a unit rate to show how you could determine if there are more than or less t

slega [8]

So 5 and 1/2 cup flour =1 and 9/16
multiply both sides by 16
80 and 16/2 cups=16 and 9
88 cups=25 pounds
divide by 5
88/5=5 pounds
multiply by 2
176/5=10 pounds
176/5=35 and 1/5
35 and 1/5 cups=10 pounds

there is MORE than 35 cups of flour in a 10 pound bag
