Ivan is 162.4 centimeters tall and is building a tower out of cans that he wants to be as tall as he is. He wants to know how many cans he will need, but he forgot to measure the length of 1 can. He knows that 10 cans are 56 centimeters tall. If he starts building the tower of cans on a stool that is 28 centimeters tall, how many cans does he need for his tower?
Answers
Answer:
Ivan will need 24 cans. 56/10 = 5.6. Each can is 5.6 cm tall. 162.4-28 =134.4

The total number of marbles Janae, Jerome and Gwen have is m + m + 4(m + 2).
m + m + 4(m + 2)
= 2m + 4m + 8
= 6m + 8
The problem says that the total number of marbles Janae, Jerome and Gwen have is less than the number of marbles John has, so that means 6m + 8 is less than 8m + 4
6m + 8 < 8m + 4.
(6m + 8) - 4 < (8m + 4) - 4
6m + 4 < 8m
4 < 8m - 6m
4 < 2m
1 and 2 aren't valid so the answer is 3, 4 and 5.

Step-by-step explanation:
Pls do not think my answer is correct im just guessing
Step-by-step explanation:
• let x be the consecutive integer• x + (x+1 )+(x+2)= -54 so we have three x's and the sum of 2 and 1 =3
=> 3x+3=-54
=> 3x=-54-3
=> 3x=-57 divide -57 for 3
=> x=-19
=> x+1= -19+1 = -18
=> x+2= -19+2=-17
there fore the three consecutive integers are -19,-18,-17
check-19+-18+-17=-54

a. 4/19
b. 4/20
c. 3/19
d. 3/20
Answers
There are now 4-1 red beans (3) and 20-1 total beans (19) so 3 out of 19 are red meaning you have a 3/19 chance of getting a red bean
20 in total. If 1 is taken out, you will have 19. There is a total of 3 red beans left. So the chance of getting a red jellybean is 3/19

Find the area of the figure. Round your answer to the nearest hundredth
Answers
Answer:
28.57 in²
Step-by-step explanation:
Okay, so the hearts tops area can be figured out with a regular circle area calculation.
A = π r² =
3.14 × 2 × 2=
6.28 × 2 ≈
12.566in ² .
So we could divided by two, but since the two half circles (the top of the hearts) are of the same size, we don't have to. So now we only have to figure out the area for the square. The radius shows us that one side of the square is equal to 4 in. So 4² or 4 × 4 = 16 in².
No all we do is add the areas: 12.566 + 16 = 28.566 in²
Now to round it: 28.566 in² ≈ 28.57 in²
