Estimate the sum by rounding each number to the given place value.

Mathematics
1 answer:
romanna [79]3 years ago
6 0

Answer:

400,000

Step-by-step explanation:

The given sum is 164,215+216,088

We simplify this to get:

164,215+216,088=380,303

The digit at the hundred thousand position is the rightmost 3.

The digit after it is 8.

Since 8≥5 we round up.

We add 1 to 3 to get 4 and replace all digits to the right with zeros.

We round to the nearest hundred thousand to get:

400,000

Gas is being pumped into a tank the total amount of gas G after amount of time T is given by the equation G= 50+20t if the total
luda_lava [24]

Answer:

T = 40 (minutes?)

Step-by-step explanation:

Given the equation G = 50 + 20T, where G = the total amount of gas and T = the amount of Time, we know that there is already 50 gallons of gas in the tank and that the rate at which it is pumped is 20 gallons per minute (I am assuming, though it is not stated in the problem).  Given that the tank holds 850 gallons, we can plug in the values into the equation and solve for the missing variable, T:

850 = 50 + 2T

Subtract 50 from both sides:  850 - 50 = 50 + 2T - 50 or 800 = 2T

Divide 2 from both sides: 800/2 = 2T/2

Solve for T:  40 = T

Pablo built a large wooden storage box. The box was in the shape of a rectangular prism, as shown below. He covered all the side
Naily [24]

The cost of wallpaper used to cover all sides of the storage box is given by $3 per square foot

<h3>Cost of wallpaper per square foot</h3>

  • length = 9 ft
  • Width = 8 ft
  • Height = 5 ft

Surface area of a box = 2(lh + wh + lw)

= 2(9×5 + 8×5 + 9×8)

= 2(45 + 40 + 72)

= 2(157)

= 314 square foot

  • Total cost of wallpaper = $942

Cost of wallpaper per square foot = $942 ÷ 314 square foot

= $3 per square foot
