An investor invested a total of ​$3 comma 500 in two mutual funds. One fund earned a 4​% profit while the other earned a 2​% pro
lesya [120]

Answer:

$2000 invested in first fund

$1500 invested in second fund

Step-by-step explanation:

An investor invested a total of ​$3,500 in two mutual funds.

Let x be the amount invested in first fund

first fund earned a 4​% profit (4%= 0.04)

So interest is 0.04x for first fund

Let x be the amount invested in first fund

first fund earned a 4​% profit (4%= 0.04)

So interest is 0.04x for first fund

Let y be the amount invested in second fund

second fund earned a =2​% profit (2%= 0.02)

So interest is 0.02y for second fund

An investor invested a total of ​$3,500 in two mutual funds.

So x+y = 3500----> equation 1

y= 3500-x

the​ investor's total profit was ​$110

0.04x + 0.02y = 110----> equation 2

Plug in 3500 -x for y

0.04x + 0.02(3500-x) = 110

0.04x + 70 - 0.02x = 110

0.02x + 70 = 110

Subtract 70 onboth sides

0.02x = 40

Divide both sides by 0.02

x= 2000

y= 3500-x

so y= 3500 - 2000 = 1500

$2000 invested in first fund

$1500 invested in second fund

What is the answer to this math problem?
Over [174]

The volume of a sphere is 4/3 x π x (diameter / 2)3, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius3. Visual on the figure below:

Making this sphere's volume 904.778684 yd3 and its cubic yards is 1,183.4.

estion 6 of 20 : Select the best answer for the question. 6. Gourds at a local farm sell for $.49 per pound. Jim Ring spent $73.
shepuryov [24]
Hey there,

#1 First step.

So we will start off on doing 73.50 ÷ .49 because Jim Ring spent 73.50 and each pound would be $.49 and we need to find out how many pound did he take. So we do 73.50 ÷ .49 and that will give us 150.

Jim Ring took \boxed{150} pounds.

Your correct answer would be A.)

Is there a direct proportion in 3y=1/2x? if there is one, what is the constant of proportionality?
kipiarov [429]
A direct proportion is any equation where y = mx+b. (i.e., a linear equation)

Each side of 3y = 1/2x can be divided by 3 to get y = 1/6x, satisfying the condition of y = mx+b. (b=0)

In this case, the constant of proportionality would be 1/6.
