Select the number that matches this list of factors:
IrinaK [193]

Answer:

12

Step-by-step explanation:

11 doesn't go into any numbers because it is prime, same with 17. 15 only goes into 3 and 5 so that's not it either. 21 only goes into 3 and 7, 26 doesn't go into 4 nor 6. 4 doesn't go into 30 evenly, so that leave just 10 and 12. 3,4,nor 6, go into 10. That leaves only 12 as the final answer.

I need help with this problem ASAP!

Form a right angle triangle joining both given points to the origin, we get:

Perpendicular = 2 ( distance is always positive)

Base = 4 ( same logic)

Applying Pythagorus theorem

Hypotenuse = root of ( perpendicular squared + base squared)

Hypotenuse = root of 20 = 2 * root 5

Using x instead of theta

Sin x = perpendicular/hypotenuse

Cos x = base/hypotenuse

Sin x = -1/ root 5

Cos x = -2/ root 5

High probability of this answer being wrong.

Double check recommended.

On Monday a Farmer sold 25196 pounds of potatoes on tuesday he sold 18023pounds on Wednesday he sold some more potatoes in all h
arlik [135]

Answer:

<em>estimated sales on Wednesday is 19000 pounds.</em>

<em></em>

Step-by-step explanation:

On Monday, he sold 25196 pounds. Estimated to the nearest thousand that is 25000 pounds.

On Tuesday, he sold 18023 pounds. Estimated to the nearest thousand, that is 18000 pounds

Wednesday's sales is unknown. We designate as x

All in all he sold 62409. Estimated to the nearest thousand, that is 62000

The sales on Monday, plus sales on  Tuesday, plus sales on Wednesday, must all sum up to the total sales.

25000 + 18000 + x = 62000

43000 + x = 62000

x = 62000 - 43000 = 19000

therefore <em>estimated sales on Wednesday is 19000 pounds.</em>

0.056\ \frac{miles}{second}

Step-by-step explanation:

we know that

The rate is equal to

200\ \frac{miles}{hour}

Remember that

1\ hour=3,600\ seconds

substitute

200\ \frac{miles}{hour}=(200/3,600)\ \frac{miles}{seconds}=0.056\ \frac{miles}{second}
