Answer:

$2000:$1500:$1000

Step-by-step explanation:

So in order to split $4500 into that proportion, we need to multiply the value by the corresponding ratios to split it properly.

There are 4 + 3 + 2 = 9 total parts to the ratio.

We know that we want the first part of the ratio to be 4/total. So we can say that:

$4500 x 4/9 = $2000. This is the first part of the ratio.

We then know the middle part of the ratio is 3/total. So we can say that:

$4500 x 3/9 = $1500. This is the middle part of the ratio.

Finally, we know that the last part of the ratio is 2/total. So we can say that:

$4500 x 2/9 = $1000. This is the last part of the ratio.

Put it all together, and we get $2000:$1500:$1000.

I hope this helps!

The logo for Chris's Calculator Company is 3 semicircles. The logo will be placed on the company building and will be 4 feet tal

Keith_Richards [23]

Answer:

The area of the logo is $18.84\ ft^{2}$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a semicircle is equal to

$A=\frac{1}{2}\pi r^{2}$

The area of the logo is equal to multiply by 3 the area of one semicircle

$A=\frac{3}{2}\pi r^{2}$

we have

$r=4/2=2\ ft$ -----> the radius is half the diameter

substitute

$A=\frac{3}{2}(3.14)(2)^{2}=18.84\ ft^{2}$

Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol

Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.

Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:

$345(1.30)^4 = \boxed{985.35}$

Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.

Help please if u can answer!:)

pentagon [3]

Answer:

ANGLE K IS 75 DEGREES

All the interior angles of a triangle ADD up to 180 degrees

lets add the angles!

6x-11+8x-29+3x-1

add like terms. all the x terms add up and all the constants as well

8x+6x+3x = 17x

-29-1-11 = -41

17x-41= 180 (-41 + 41 = 0 we do this to remove -41 from the left side of the equation to isolate x)

41+180 = 221

17x=221

221/17 = 13

x=13

so..

8 * 13 - 29 is the angle..

8*13 = 104

and 104-29 = 75

Angle K is 75 degrees! hope that helps..

Answer:

0.75 ft/min

Step-by-step explanation:

Given;

Length of trough l = 8 ft

base length of trough b = 3 ft

height of trough h = 1 ft

Change in volume dV/dt = 12 ft^3/min

At height hi = 8 in = 2/3 ft

Ratio of base to height;

b/h = 3/1

b = 3h .....1

The volume of the trough;

V = area of triangle × length

V = 1/2 × b×h × l

V = 1/2(bhl) .....2

Substituting l = 8ft and equation 1 (b = 3h) into equation 2;

V = 1/2(3h × h × 8)

V = 12h^2

differentiating V, change in volume per time is;

dV/dt = 12 × 2h .dh/dt

dV/dt = 24 hi .dh/dt

Substituting the values of dV/dt and hi;

12 = 24(2/3) .dh/dt

dh/dt = 12 ÷ 24(2/3) = 12/16

dh/dt = 3/4 ft/min = 0.75 ft/min
