Answer:  

83 Tenths  

830 hundreths  

Step-by-step explanation:  

8.30=8.3 Remove the points and they will give you how many tenths or hundreths

(hope this helps can i plz have brainlist :D hehe)

Answer:

8.3 tenths place is 3

8.3 hundredths place is 0

Why?

Because the first digit right of the decimal point will always be considered the tenths place, the second digit of the right of the decimal point is going to be the hundredths place, in this case it is 0 since there is no value of the hundredths place so you simply consider it 0. The tenths place is given since it is the first digit right of the decimal point, which is 3.

Answer:

Step-by-step explanation:

From the question we are told that:

Lower quartile [tex]x=45[/tex]

Upper quartile [tex]y=87[/tex]

Generally the equation for Mean is mathematically given by

 [tex]\=x=\frac{Upper+Lower}{2}[/tex]

 [tex]\=x=\frac{x+y}{2}[/tex]

 [tex]\=x=\frac{45+87}{2}[/tex]

 [tex]\=x=66[/tex]

Since Median m is half middle of distribution

 [tex]m=\frac{Upper+Lower}{2}[/tex]

Therefore

 [tex]\=x=m[/tex]

 [tex]m=66[/tex]

Answer:

its c????

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

2a+3b=5

2a+3(a-5)=5

2a+3a-15=5

5a=5+15

5a=20

a=4

b = a - 5

_________________________

2a + 3b = 5

2a + 3( a - 5 ) = 5

2a + 3a - 15 = 5

5a - 15 = 5

5a - 15 + 15 = 5 + 15

5a = 20

5a ÷ 5 = 20 ÷ 5

a = 4

_________________________

b = a - 5 ===》 b = 4 - 5 ===》 b = - 1

Answer:

The probability that the first marvel will be red and the second will be green is 7.14%.

Step-by-step explanation:

Since a bag contains 2 red marbles, 2 green marbles and 4 blue marbles, if we choose a marble and then other marble without putting the first one back in the bag, to determine what is the probability that the first marvel will be red and the second will be green, the following calculation must be performed:

2 + 2 + 4 = 8

2/8 x 2/7 = X

0.25 x 0.2857 = X

0.0714 = X

Therefore, the probability that the first marvel will be red and the second will be green is 7.14%.

B & D

Step-by-step explanation:

If you do 30x10 it would equal 300

So that wouldn't be it. If you do 49x100 that will equal 4,900 which is correct. If you do 40x600 that would equal 24,000 which is also incorrect. The last one is correct because 400x80 is 32,000

Answer:

B

Step-by-step explanation:

Answer:

71 in²

Step-by-step explanation:

surface area = (4×6)+(2×½×4×5)+(2×½×6×4.5)

= 24+20+27 = 71 in²

4x - 4y = -4

- (4x + y = 16)

___________

5y = -20

Now on solving the equation we have:

= 5y = -20

= y = -20/5

= y = -4

If y = -4 then,

= 4x + y = 16

= 4x + (-4) = 16

= 4x = 16 + 4

= x = 20/4

= x = 5

Thus, x = 5, y = -4

Answer:

(8 , -4)

Step-by-step explanation:

____________________

The new coordinate after rotating it 180 degrees around the origin will be;

⇒ (8, - 4)

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

The point is,

(- 8, 4)

And, It rotating it 180 degrees around the origin.

Now,

The rule of the transformation to rotating it 180 degrees around the origin is;

(x, y) ⇒ (- x, - y)

Thus, The new point after rotating it 180 degrees around the origin is,

(- 8, 4) = (8, - 4)

Therefore, The new coordinate after rotating it 180 degrees around the origin will be;

⇒ (8, - 4)
