2 sack of cement is needed to cover entire floor of Joel
<em><u>Solution:</u></em>
Given that a sack of cement is enough to cover a floor with a total area of 45 sqft
Joel’s floor length is 8ft by 7ft
To find: Number of sacks needed to cover entire floor of Joel
Let us first find area of Joel's floor
Since the floor is generally of rectangular, we can use area of rectangle
<em><u>So the total area of floor with length 8 feet and width 7 feet is:</u></em>
Thus the total area of floor is 56 square feet
<em><u>Let us now find number of sacks needed to cover entire floor</u></em>
Given that, one sack of cement covers 45 square feet
Since Sack of cement cannot be in point value hence we can say 2 sack of cement is required.
Another way to group the factors can be like this:
6 x 4
8 x 3
12 x 2
The product regardless would be 24.
Answer:
Angela is 13 years old and Angela's aunt is 41 years old.
Step-by-step explanation:
With the information provided you know that Angela's aunt is two more than three times her age, which could be expressed as:
x=3y+2, where:
x is Angela's aunt age
y is Angela's age
Also, you know that the total of their ages is 54, which is:
x+y=54
Now, you can replace x=3y+2 in x+y=54 and solve for y:
3y+2+y=54
4y=54-2
4y=52
y=52/4
y=13
Finally, you can replace the value of y in x=3y+2 to find x:
x=3(13)+2
x=39+2
x=41
According to this, the answer is that Angela is 13 years old and Angela's aunt is 41 years old.
92 5/6 + 45 6/12 - 32 9/12 = 105 7/12
105 7/12 divided by 29 2/12 = 3 31/50
They are the same type of triangles and same measurements
