Ajay reads aloud from a sports magazine. He comes across the measurement 0.63 kilometer. How should he read this measurement alo

Mashutka [201]

Answer:

"sixty-three hundredths of a Kilometer"

Step-by-step explanation:

Decimal measurements are read based on the place of their digits. In this case, Ajay would read this measurement as "sixty-three hundredths of a Kilometer". This is because the final digit of the decimal form measurement is in the "hundredths" position. One more to the right and it would be in the "thousandths" while one more to the left would be the "tenths"

Emily and Andy each go to a hardware store to buy wire.The table shows the relationship between the cost and the length of wire.

Lady_Fox [76]

Answer:

So, Emily will spend, 11.52 unit on wire

and, Andy will spend 18.72 unit on wire.

Step-by-step explanation:

Cost of wire is = $\frac {4.80}{120}$

= $\frac {5.40}{135}$

= $\frac {6.00}{150}$

= $\frac {7.00}{175}$

= 0.04 unit/inch

We know that,

12 inch = 1 foot and

1 yard = 3 foot [Note that unit of a quantity always denoted singular].

So, Emily will spend,

$24 \times 12 \times 0.04$ unit

= 11.52 unit on wire

and, Andy will spend,

$13 \times 3 \times 12 \times 0.04$ unit

= 18.72 unit on wire.

The first barn contained 3 times more hay than the second one. After 20 tons of hay were removed from the first barn and 20 tons

pentagon [3]

Answer:

Amount of hay in first barn = 90 tons

Amount of hay in second barn song = 30 tons

Step-by-step explanation:

Let the amount of hay in second barn be x, then hay in first barn will be 3x.

20 tons of hay was removed from first barn and ws added to second barn.

Now, the amount of hay in first barn = 3x -20

Amount of hay in second barn = x+20

The equation now formed is:

x+20 = $\frac{5}{7}$ (3x-20)

7x+14 = 15x -100

-8x = -240

8x = 240

x = 30

3x = 90

Amount of hay in first barn = 90 tons

Amount of hay in second barn song = 30 tons
