The sum of 1/3 and twice a number is equal to 2/3 subtracted from three the number.find the number
Zigmanuir [339]
The number = y

2y + 1/3 = 2/3 - 3y
(add 3y to both sides)
5y + 1/3 = 2/3
(subtract 1/3 from both sides to isolate y)
5y = 1/3
(divide by 5)
y = 1/15

In the figure, a square is inside another bigger square.
evablogger [386]

Answer:

Part 1) The length of the diagonal of the outside square is 9.9 units

Part 2) The length of the diagonal of the inside square is 7.1 units

Step-by-step explanation:

step 1

Find the length of the outside square

Let

x -----> the length of the outside square

c ----> the length of the inside square

we know that

x=a+b=4+3=7\ units

step 2

Find the length of the inside square

Applying the Pythagoras Theorem

c^{2}= a^{2}+b^{2}

substitute

c^{2}= 4^{2}+3^{2}

c^{2}=25

c=5\ units

step 3

Find the length of the diagonal of the outside square

To find the diagonal Apply the Pythagoras Theorem

Let

D -----> the length of the diagonal of the outside square

D^{2}= x^{2}+x^{2}

D^{2}= 7^{2}+7^{2}

D^{2}=98

D=9.9\ units

step 4

Find the length of the diagonal of the inside square

To find the diagonal Apply the Pythagoras Theorem

Let

d -----> the length of the diagonal of the inside square

d^{2}= c^{2}+c^{2}

d^{2}= 5^{2}+5^{2}

d^{2}=50

d=7.1\ units

Use a division ladder to find the GCF of 34 and 60. A4 B3 C1 D2
Sloan [31]

Answer:

D.2


Step-by-step explanation:

First, you need to divide 34 and 60 by A.4, when you divide that you see that 4 dose not go in to 34 evenly and go"s in to 60 evenly, so this is incorect.


Now we will divide 34 and 60 by B.3, when you divide, you see that 3 dose not go into 34 evenly and go"s in to 60 evenly, so this is also incorect.


Then we divide 34 and 60 by C.1, when we divide this one you find that 1 go"s in to 34 evenly and 60 evenly, so this is a posible answer.


finally we divide 34 and 60 by D.2, when we do this we find that 2 go"s in to 34 evenly and 60 evenly, so this is also a posible answer.


All though C. and D. both go in to 34 evenly and 60 evenly, we are looking for the GCF (Greatest Common Factor). So the biggest number of C.1 and D.2, is D.2


So the answer is D.2.


Hoped this helped, Have a grate day!

At the moment a hot iron rod is plunged into freezing water, the difference between the rod's and the
jonny [76]

Answer:

<h2>The function is</h2><h2>D(t) = 100 \times( \frac{40}{100} )^{t}</h2>

Step-by-step explanation:

At t = 0 the difference is 100 degree celsius.

After one second the temperature difference will be 100 - \frac{100\times60}{100} = 100(1 - \frac{60}{100} )

After two second, the difference will be 100(1 - \frac{60}{100} )(1 - \frac{60}{100} ) = 100(1 - \frac{60}{100} )^{2}

Hence, it can be written that,

D(t) = 100 \times(1 - \frac{60}{100} )^{t} = 100 \times( \frac{40}{100} )^{t}
