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 pepper plants are in the garden?

Answers

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!

What is the length of the base of a right triangle with an area of 20 square meters and a height of 4 meters? 5 m 10 m 80 m 160 m

Answers

you find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m

The deminsions of a rectangler prism are 5cm, 6cm, and Xcm. Its surface area is 148 cm2. Find the other deminsion.​

Answers

Answer:

The other dimension is x=4 cm

Step-by-step explanation:

Surface Area of a Rectangular Prism

Given a rectangular prism of dimension x, y, and z. Its surface area is calculated with the formula:

A = 2(xy + yz + xz)

We are given the dimensions y=5 cm and z=6 cm. We also have A=148 cm2. Substituting:

148 = 2(x*5 + 5*6 + x*6)

Dividing by 2:

74 = x*5 + 5*6 + x*6

Operating:

74 = 5x + 30 + 6x

Simplifying:

74 = 11x + 30

Subtracting 30:

44 = 11x

Dividing by 11:

x = 4 cm

The other dimension is x=4 cm

100 points!

Answers

Answer: 6 feet


Explanation: Since the triangles are similar, we can use the proportion 9/4=(12x+2)/(5x+1).

Cross multiplying 9*(5x+1) and 4*(12x+2) gives us 45x+9=48x+8.

Solving for x gives us 1/3.

You can check your work by plugging in x for the two equations, which gives us 6 (RS) and 8/3 (R’S’)

The scale factor is 4/9 (k) from 9k=4

6*4/9=8/3 and (8/3)/(4/9)=6

Answer:

RS = 6 feet

Step-by-step explanation:

Use ratios of corresponding sides:

TS/T'S' = RS/R'S'

Substitute and solve for x:

9/4 = (12x + 2)/(5x + 1)9(5x + 1) = 4(12x + 2)45x + 9 = 48x + 848x - 45x = 9 - 83x = 1x = 1/3

Find the length of RS:

RS = 12x + 2 = 12(1/3) + 2 = 4 + 2 = 6 feet

x = 4, 8, 12

2) x + 3 ≥ 15 ⇒ x ≥ 12

x = 12

3) 19 > x + 4 ⇒ 15 > x ⇒ x < 15

x = 4, 14

4) 12 ≥ 6x ⇒ 2 ≥ x ⇒ x ≤ 2

x = 1, 2

5) 7x ≤ 21 ⇒ x ≤ 3

x = 1, 2, 3

6) 5 + x < 7 ⇒ x< 2

x = 1

7) x - 5 < 17 ⇒ x < 22

x = 9, 14, 15

The strategy that we are using here is PEMDAS:

First, you subtract 6 from 10 which is 4. 10 - 6 =4

Next, you multiply 4 by 3. 4 × 3 = 12

Then, you divide 12 by 2. 12 ÷ 2 = 6
