A rectangular tank is 100 cm long, 30 cm wide and 12 cm deep. What is the estimated capacity of the tank half full? Hint: 1000 c
Licemer1 [7]
To figure this out, you need to multiply all the dimensions together. 100x30=. 3,000cm and 3,000x12= 36,000 cubic centimeters. So now you can divide the 36,000 by 1000 to get the amount of liters the entire tank can hold. 36,000/1000= 36 liters. And because you want to know how much half of the tank is, you divide 36 by 2 and get 18 liters

Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. What is the ratio of
natta225 [31]

Answer:

ratio of regular to diet soda = 16/9

Step-by-step explanation:

Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. This means

Number of cans of regular soda = 32

Number of cans of diet soda = 18

Total number of soda brought to the family picnic = number of cans of regular soda + number of cans of diet soda

= 32 + 18= 50

the ratio of regular soda cans to diet cans in the cooler= 32/18

Divide numerator and demo minator by 2, we have 16/9.

The fraction cannot be reduced further. So ration of regular to diet soda = 16/9

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of third angle os 88 degrees
Volgvan

Answer:

Answers: 46, 23, and 111

Step-by-step explanation:

To answer, we need to know the angles. Therefore, give each angle a name. Angle 1 will be x, 2 will be y, 3 will be z. So, using this system of equations:

x=2y

z=y+88

x+y+z=180

Substituting, z = 1/2(x)+88, now plug z into the third equation:

x+1/2(x)+1/2(x)+88=180

this simplifies to 2x+88=180

subtracting 88 from both sides leaves 2x=92

x=46

plug this in to the first equation: 46 = 2y, so y = 23

plug this into the third one leaves z = 111

Hope this helps!
