Answer:

3j + 3m + 21

Step-by-step explanation:

Normally, they would each travel 3 miles, so the total would normally be 3j + 3m. However, for today, Jared ran another 21 miles, so 21 miles is added to the total.

Total distance = 3j + 3m + 21

Answer:

(3j) + (3m + 21)

Step-by-step explanation:

Since every time Jared goes running he runs 3 miles we should multiply j by 3. So we will have: 3j

Since every time Malia goes running she runs 3 miles we should multiply m by 3. So we will have 3m

But this month Jared ran an extra 21 miles so we will have to add that after we have multiplied both j and m by 3.

Since we want the total distance they ran that month, we need to add all of these distances.

This will give us 3j + 3m + 21.

In the answer options 3j is inside a parenthesis as well as 3m + 21. Since inside the parenthesis we only have addition and the order which we add doesn't really make a difference, the parenthesis were unnecessary but they won't affect the answer.

I know how to do this and the teacher don't teach it right so I don't get how to do it at all

I dont have time to do all of these right now my apolgies but Ill explain how to do it.

The 3 angles of a triangle add up to 180.

So let me show you how to do 1.
.
.
.

1. 58 degrees

92, 30, ?

If we add together the first two angles,
92+30= 122
Knowing the total addition of all three angles would ne 180, we can subtract 122 from it to get the third angle.
180-122= 58

So we now know the last angle is 58 degrees because

92+30+58=180

What is greater, 85/100 or 21/25?
Elodia [21]


85/100 is greater

85/100=.85 or 85%

21/25=.84 or 84%

.85 is greater than .84 so 85/100 > 21/25

alina1380 [7]

Answer:

1.89 is the standard deviation of households who own a riding mower

Step-by-step explanation:

Let the random variable X denote the number of households owning a riding lawn mower. From the given information, X will be a Binomial random variable with parameters; n = 17 and  p = 30% = 0.3

The standard deviation of X;

\sqrt{n*p*(1-p)}

\sqrt{17*0.3*(1-0.3)} =1.89
