758 round to the nearsest hundred

Allisa [31]

If a number has three digits (like 758, 999 or 125) you take a look at the second last digits. If they are higher than 50 you round the first digit up. Otherwise you round it down. Finally you add two zeros.

In case of 758, the last two digits are 58. It is more than 50 so you round 758 to 800.

Hope it helps!

Can someone help?<br> Need to find x, and measure of angle DEF

Colt1911 [192]

Answer:

x = 5

$m\angle DEF = 90\degree$

Step-by-step explanation:

GE is the angle bisector of quadrilateral DEFG,

Thus, by angle bisector property:

9x°= (5x + 20)°

9x = 5x + 20

9x - 5x = 20

4x = 20

x = 20/4

x = 5

$m\angle DEF = 9x\degree + (5x+20)\degree$

$m\angle DEF = (14x+20)\degree$

$m\angle DEF = (14\times 5+20)\degree$

$m\angle DEF = (70+20)\degree$

$m\angle DEF = 90\degree$

PLEASE HELP!!

Nesterboy [21]

First, we need to find the volume of the pan. We do this by multiplying the length, width, and height together. This is:

$volume=10*12 \frac{1}{2} *2=250 in^{3}$

Next, we find the volume of the pieces of bread. We do this the same way.

$volume=2*2 \frac{1}{2}*2=10in^{3}$

Finally, we figure out how many times 10 can go into 250. We do this by dividing 250 by 10.

250/10=25, so Arla can cut 25 pieces of bread.
