In the number 15.2201 how does the value of 2 in the tenths place compare to the value of the 2 in the hundredths place
lakkis [162]

Answer:

The 2 in the hundreths is 10% of the 2 in the tenths

Step-by-step explanation:

We are given the number 15.2201

#The value of 2 in the tenths:

0.2

#The value of 2 in the hundredths:

0.02

The difference of the 2 in the tenths and in the hundredths is:

=2_t-2_h\\\\=0.2-0.02\\\\=0.18\\\\\#2_h \ as \ a \ \% \ of \ 2_t\\=\frac{2_h}{2_t}\times 100\%\\\\=\frac{0.02}{0.2}\times100\%\\\\2_h=10\% \ of\  2_t

Hence, the difference between the 2 in the tenths  minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.

Someone please help thanks :))))
Sedaia [141]

Answer:

-2

Step-by-step explanation:

We can find the slope by using the slope formula

m = (y2-y1)/(x2-x1)

    = (-5 - -7)/ ( -2 - -1)

    = ( -5+7) / ( -2 +1)

    = 2/-1

   = -2

Its line segment please
joja [24]

Answer:

A) 29

Step-by-step explanation:

DG = GJ

GJ = DG = 4x + 17

DJ = DG + GJ

11x + 25 = 4x + 17 + 4x + 17

11x + 25 = 4x + 4x + 17 + 17    {Combine like terms}

11x + 25 = 8x + 34

Subtract 25 from both sides

11x = 8x + 34 - 25

11x = 8x + 9

Subtract 8x from both sides

11x - 8x = 9

3x = 9

Divide both sides by 3

x = 9/3

x = 3

DG =  4x + 17

     = 4*3 + 17

    = 12 + 17

DG = 29

12) This one would be (b) because if you were reading it out loud it would be 2 is less than 3x, and 3x is greater than 5.

13) To make this easier for you I would change everything to a decimal.
Peaches: 3.25 pounds
Mangos: 4.35 pounds
Since the peaches are .89 per pound you times
3.25(.89)=2.8925 (which rounds to 2.89)
Since the magpies cost 1.26 per pound you would times
4.375(1.26)=5.5125 (rounds to 5.51)
Then 5.51-2.89=2.62
So the answer is A

14)3x is greater than or equal to nine
In this case x would have to be three or greater. So the answer would be B

15) The answer is B

16)c
— -5=20
2
You first get rid of your constant which in this case is -5, so you add 5 to both sides.
C
— -5=20
2
+5 +5
Then you would get
C
— =25
2
Now you want to try to get the variable alone, so you cancel the twos out, what you do to one side you have to do to the other.
2 C
— =25(2)
2
C=50
The answer is D
