The ratio of tomatoes to pepper plants in the garden is 5:2. If there are 6 more tomato plants than pepper plants, how many pepp
Kay [80]

The ratio from tomatoes to pepper plants is 5:2

Meaning there are 5 tomatoes and 2 pepper plants

In order to find a ratio where there are 6 more tomatoes than pepper plants you will have to multiply.

-----

When the ratio 5:2 is multiplied by 2

it equals 10:4

We can stop here because it is shown that now there are 6 more tomatoes than pepper plants.

-----

So there are:

10 tomatoes

and

4 pepper plants!

Answer:

Step-by-step explanation:

R=50+20t, B=150-20t they will be the same height when

50+20t=150-20t

50+40t=150

40t=100

t=2.5, usingvthis value for t in either original equation will give you the height.

h=50+20(2.5)

h=100m

Please help m solve this it's about shaded areas. I need it fast. PLZ HELP THANK YOU IF YOU DO AND U R SO AMZING IF U DO&gt;
sukhopar [10]

A = area of the circle

A = pi*r^2

A = pi*11^2

A = 121pi

-----

B = area of the rectangle

B = length*width

B = 6*4

B = 24

-----

C = blue shaded area

C = A - B

C = 121pi - 24 which is the exact area in terms of pi

C = 356.1327 is what you'd get if you used a calculator

C = 356.13 is the result after rounding to the nearest hundredth

<h3>The final answer is 356.13</h3>
