C= 615.44
c=3.14(r)^2
c=3.14(14)^2
Answer:
option 4
Step-by-step explanation:
so first you would simplify to x>-6 and since there is no line under the greater then it would be and open circle and it is shading to the right because of the greater than symbol and if would start of -6 so option 4 is the correct answer
Step-by-step explanation:
distance formula d=
√(X2 - X1)² + (Y2 - Y1)²
= √(-9-15)² + (8-3)²
=√(-24)² + (5)²
=√576 + 25
=√601
Answer:
31°
3
108°
Step-by-step explanation:
The measure of angle ADB is congruent to the measure of angle CBD, so it is equal to 31°.
4x = 12
divide by 4 on both sides and you are left with x=3
angle A is congruent to angle C, so it is equal to 108°.
Hope this helps!
Answer:
The cost of one cup of hot chocolate is $4.50
Step-by-step explanation:
Let
x ----> the cost of one cup of hot chocolate
y ----> the cost of one cup of hot tea
we know that
3x+4y=25.50 ------> equation A
y=(2/3)x -----> equation B
Solve the system of equations by substitution
substitute equation B in equation A and solve for x
3x+4(2/3)x=25.50
3x+(8/3)x=25.50
(17/3)x=25.50
x=25.50*3/17
x=$4.50
therefore
The cost of one cup of hot chocolate is $4.50
