Assuming the +'s are actually x's 1/2 of 3 is 1.5 and 1.5 divided by 7 is 1.5/7.(answer is 1.5/7) hopefully I'm right.
Answer:
the radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying the formula for finding the area of a circle.
area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the radius of the circle is 6cm
Answer:
Peanuts cost $2 a bag
Almonds cost $2.50 a bag
Step-by-step explanation:
To solve, write a system of equations using the information given.
- "a small case contains 10 bags of almonds and 25 bags of peanuts for $75" translates to 10a+25p=75
- "a large case comtains 40 bags of almonds and 60 bags of peanuts for $220" translates to 40a+60p=220
Solve by stacking the equations and performing elimination. To eliminate a variable, the coefficients must be the same. To make this so, we will multiply 10a+25p=75 by 4 to become 40a+100p=300. Now stack the equations and subtract:
40a+100p=300
40a+60p=220
----------------------------
0a + 40p=80
p=2 means peanuts cost $2 a bag.
Substitute p=2 into one equation to find a.
10a+25(2)=75
10a+50=75
10a=25
a=2.5 means almonds cost $2.50 a bag.
let's solve your equation step-by - step
-3-3/4(c-4)=5/4
Step 1: simplify both sides of the equation.
-3-3/4(c-4)=5/4
-3+-3/4 c+3=5/4 (distribute)
(-3/4 c)+(-3+3)=5/4 (combine like terms)
-3/4c=5/4
-3/4 c =5/4
Step 2: Multiply both sides by 4/(-3)
(4/-3)*(-3/4 c)=(4/-3)*(5/4)
Answer:c=-5/3
A = P(1+r/n)^<span>(nt)
A = 32,000(1+0.03/4)^28
A = 39,446.78 ...........this is your answer</span>
