Answer:
The unit price of the problem is that one pack of greeting cards costs $1.85
Step-by-step explanation:
In order to find the unit rate, you have to divide the price by the quantity of the product. So, we will divide 7.40 by 4 so we can see the price of one pack.
7.40 ÷ 4 = 1.85
So, one pack of greeting cards costs $1.85 which is also our unit price.
Answer:
10859.94
Step-by-step explanation:
To solve this, you need to know the formula for solving the area of a circle: πr²
The first thing you should do is find the area of the square: 78 x 78 = 6084
Then, we find the area of the circle. To do this, we must figure out the radius. Luckily, the problem states that the combined diameter of both half circles is 78, which means the radius is 39. Then, we can apply the formula: π39².
39² = 1521
1521 x 3.14 = 4775.94
This is the combined area of both half circles.
Finally, we have to add: 4775.94 + 6084 = 10859.94
Answer:
72cm³
Step-by-step explanation:
Base of the triangular face =3 cm.
Height of the triangular face = 4 cm.
Length of the prism = 12 cm.
Volume of a Prism= Base Area X. length
The base of a triangle prism is a triangle, therefore:
Volume of a Triangular Prism= ½bh X Length
=½ X 3 X 4 X 12
=½ X 144
=72cm³
Volume of the triangular Prism= 72cm³
Answer:
x = 10
y = 1
DE = 7
AC = 14
Step-by-step explanation:
x + 2 = 24/2
x = 12 - 2
x = 10
y + 6 = x - 3
y = 10 - 3 - 6
y = 1
Answer:
A
Step-by-step explanation:
Essentially, to use the method of division the question is mentioning you need to divide 21 by 3/4. Use fraction rules to divide meaning (21*4/3). This gets you m + 12 = 84/3. If you simplify the right side you get 28. Thus, the final answer is the first option choice.
Hope this helped :)
