Answer:
1,152,112.5 cm3
Step-by-step explanation:
To find the volume of this mailbox we can separate in two parts:
A rectangular prism, with dimensions 180 cm x 70 cm x 85.5 cm and
A triangular prism, with dimensions 25 cm x 70 cm x 85.5 cm.
Now we need to find the volume of both parts:
V_rectangular = 180 * 70 * 85.5 = 1,077,300 cm3
V_triangular = (1/2) * 25 * 70 * 85.5 = 74,812.5 cm3
Finally, we just need to sum the volumes of the parts:
V_mailbox = V_rectangular + V_triangular = 1077300 + 74812.5 = 1,152,112.5 cm3
Answer:
C
Step-by-step explanation:
To form a proportion, you need two equal ratios.
Divide the numerator by the denominator of all fractions.
Any two fractions that are equal are a proportion.
A.
4/9 = 0.4444...
9/4 = 2.25
Fractions are not equal. Not a proportion.
B.
4/10 = 0.4
10/25 = 0.4
Fractions are equal. Proportion
C.
4/11 = 0.363636...
6/13 = 0.46153846...
Fractions are not equal. Not a proportion.
D.
I can't read the fractions, but do the same I did above.
Divide each numerator by the denominator and compare the decimals. If they are equal its a proportion. If theya re not equal, it is not a proportion.
