Answer:
2.15d+3.12 = 11.72
Step-by-step explanation:
The total cost is found by adding the costs of the donuts and the cost of the drink
The donuts cost 2.15 per donut = 2.15d
The drink is 3.12
She spent 11.72
2.15d+3.12 = 11.72
Answer:
80 sq units
Step-by-step explanation:
Starting with the largest rectangle, we see it has a width of 6 and a length of 8, meaning the area of that only is 48 sq units. (area of rect. = l x w, so 6 x 8 is 48)
There are two smaller rectangles with width 6 and length 2. One of those rectangles would be 12 units (6 x 2). Since there is two of them, then 24 sq. units.
Lastly, there are four small triangles. The area formula for a triangle is 1/2(b)(h). The triangle has a base of 2 and a height of 2. (1/2)(2)(2) =2. Since there are four triangles, the total for them only would be 8 (2 x 4).
Adding each of these pieces together will give us the answer:
48+24+8=80 sq units
P=26x+25
You must add like terms.
Check the picture below.
a)
notice, since lines KP and NL are parallel, they make up the same angle in purple when they hit line MK, and both triangles share the green angle at M.
b)
notice, LP = LK = 14, and in an isosceles twin sides stemming from a vertex make twin angles.
The answer is 1 : 1 : square root of 3
