Answer:
10 water bottles
Step-by-step explanation:
We know that there are a total of 1000 milliliters in a 1 liter. So we first need to multiply 1000 milliliters by 5 in order to calculate how much is in 5 liters which is what the coach is asking for...
1000 * 5 = 5000 milliliters
Since each water bottle only holds 500 milliliters we need to divide this amount by the total that the coach needs in milliliters.
5000 / 500 = 10
Finally, we can see that Audrey needs to buy a total of 10 water bottles to have exactly enough water.
Answer:
160 square units
Step-by-step explanation:
We need to find the surface area of this figure, which is basically the areas of all the exterior sides.
Looking at the pyramid, we notice that we have 4 congruent triangles and 1 square.
<u>Triangles</u>:
The area of a triangle is denoted as A = (1/2) * b * h, where b is the base and h is the height. Here, the base is 8, so b = 8, and the height is 6, so h = 6. Plug these values in to get the area of one triangle:
A = (1/2) * b * h
A = (1/2) * 8 * 6 = (1/2) * 48 = 24
The area of one triangle is 24 square units, so the area of 4 is 24 * 4 = 96 square units.
<u>Square</u>:
The area of a square is denoted by: A = s * s = s². Here, s = 8, so plug that in:
A = s²
A = 8² = 8 * 8 = 64
The area of the square is 64 square units.
Now add up the areas of the triangles and square:
96 + 64 = 160 square units
The surface area is 160 square units.
the answer is B 37 your welcome
Please retake the pic because it’s blurry. I don’t know if it’s my internet or you took it that way because it is too blurry.
Answer:
$93.22
Step-by-step explanation:
bill = $79
tip = 18%
tip amount = tip % of bill
=18/100 * $79
=$1422/100
=$14.22
total cost = $79 + $14.22
=$93.22
