How do you round 328 to the nearest ten

Answers

Answer 1

Answer: 328 rounded to the nearest ten so where would your tens place be
328
the 2 is in the tens place now how to round to the nerest tens place look to the right of the tens place
4 and lower numbers go DOWN
5 and higher numbers go UP
so the 8 is in the higher numbers so you would bring 328 up to 330
so 328 rounded to the nearest ten would be 330

The measure of arc ABC is 283°.

Step-by-step explanation:

We know that the whole arc is equal to 360°, that means

$AC+AB+BC=360$

Where $AC=7y-7$ , $AB=4y+6$ and $BC=20y-11$ . Replacing these expressiones, we have

$7y-7+4y+6+20y-11=360\n31y-12=360\n31y=360+12\ny=(372)/(31)\ny=12$

But, arc ABC is defined by the sum of arcs AB and BC:

$ABC=AB+BC=4y+6+20y-11=24y-5=24(12)-5=283$

Therefore, the measure of arc ABC is 283°.

Answer:

Arc measure of ABC is 283°

Step-by-step explanation:

We know the total angle of the circle is 360°.

Therefore,

(20y - 11) + (4y +6) + (7y - 7) = 360°

Collecting like terms, we have:

20y + 4y + 7y = 360 + 7 - 6 + 11

31y = 372

Let's divide both sides by 31.

$(31y)/(31) = (372)/(31)$

y = 12

The arc measure of ABC is the sum of AB and BC. To find the arc measure of ABC, we have:

(4y +6) + (20y - 11)

Collecting like terms, we have:

4y + 20y + 6 - 11

24y - 5

Let's substitute 12 for y

24(12) - 5

288 - 5 = 283°

Arc measure of ABC is 283°

Given:AB||CD .If the coordinates of point A are (8, 0) and the coordinates of point B are (3, 7), the y-intercept of AB is____ ? If the coordinates of point D are (5, 5), the equation of line CD is y___ = ___x + ____

Answers

(8,0)(3,7)
slope = (7-0) /(3-8) = -7/5

y = mx + b
slope(m) = -7/5
(3,7)

7 = -7/5(3) + b
7 = -21/5 + b
7 + 21/5 = b
35/5 + 21/5 = b
56/5 = b

y = -7/5x + 56/5 <=== the y int of AB is 56/5

y = mx + b
slope(m) = -7/5
(5,5)

5 = -7/5(5) + b
5 = - 7 + b
5 + 7 = b
12 = b

y = -7/5x + 12 <=== equation of line CD

Answer:

first blank : 56/5

second blank : -7/5

third blank : 12
