Answer: 6.24 tablespoons
Explanation: okay so if $.39 is 2 tablespoons, then you can multiply that by 8 because there are 8 tablespoons in half a cup. After you multiply that just multiply it by 2 because they are trying to make two pies. And that’s how you your answer.
The central angle measure of the sector is 4.19 rad.
<h3>Area of a Sector</h3>
You need apply the formula: for finding the area of the sector, in radians. In this formula, the variables are:
r= radius
= central angle
The question gives:
A=54 cm²
r= radius= 9cm
Thus, the central angle will be:
For =3.14159..., you have :

The perimeter of a shape is the sum of its side lengths
Becca, Lucas, and Christian are correct
<h3>How to determine the correct perimeter</h3>
The side lengths of the triangle are x, 3x - 4 and 3x - 4
So, the perimeter (P) is:
P = x + 3x - 4 + 3x - 4
The above equation can be rewritten as:
P =2(3x - 4) + x
P = 6x + x - 4
P = (3x - 4) + (3x - 4) + x
P = 7x - 4
Hence, Becca, Lucas, and Christian are correct

Answer:
Step-by-step explanation:
3x + 9x +12 = 180 {linear pairr}
12x + 12 =180
12x = 180 - 12
12x = 168
x = 168/12
x = 14
3x = 3*14 = 42
4y - 10 + 3x = 180 {linear pair}
4y - 10 + 42 = 180
4y + 32 =180
4y = 180 - 32
4y = 148
y = 148/4
y = 37
Answer:
Sn=a+(n-1)d
n=60,a=-10,d=8-(-10)=8+10=18
S60=-10+(60-1)18
S60 =-10+(59)18
S60=-10+1062
S60 =1052
