A plant is already 53 centimeters tall, and it will grow 1 cm every month.

Let H be the plants height (in centimeters) after M months.

Write an equation relating H to M. Then use this equation to find the plant height after 26 months.

Answers

Equation: h = 53 + 1m

Solving for m = 26: h = 79

The plant will be 79cm tall after 26 months

The height of the plant, H, is related to the number of months, M, by the equation H = M + 53. The plant will be 79 centimeters tall after 26 months.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The height of the plant, H, is related to the number of months, M, by the equation H = M + 53.

This equation represents the plant's initial height of 53 centimeters plus the additional height it will grow each month.

To find the plant's height after 26 months, we can substitute M = 26 into the equation:

H = M + 53

H = 26 + 53

H = 79 cm

So, the plant will be 79 centimeters tall after 26 months.

pls help!!!​

Answers

Answer:

1) 11/100 or 0.11

2) 3/1000 or 0.003

3) 113/1000 0.113

Step-by-step explanation:

Firstly, hundredths is the same as 1/100.

Multiply every number by 1/100.

11/1 • 1/100 = 11/100 or 0.11

(Remember, 11 over 1 is the same as 1. Multiply the numerators and denominators and you get 11/100).

3/10 • 1/100 = 3/1000 or 0.003

11.3/1 • 1/100 = 113/1000 or 0.113

(Move the decimal once to the right to get rid of the decimal point).

what is the mean of this set
0,100,100,100,100​

Answers

80

Step-by-step explanation:

Mean simply means the average. To calculate the average of all these numbers, add them all up together and divide that number by how many numbers you added.

A simple equation you can use is:

[tex]\frac{the sum of the terms}{the number of terms}[/tex]

To calculate the mean of the set : 0,100,100,100,100​

= 0 + 100 + 100 + 100 + 100

= 400 / 5

O x = 2, y = 7,2 = 2

x = 3, y = 6,2 = 4

x = 6.) = 3,2 = 4

Answers

Answer:

x = 3, y = 6, z = 4

Step-by-step explanation:

If lines s, t, and u are perpendicular bisectors of the sides of APGH and meet at J, then JG = JH = JF = HI

Given

JG - 2x+ 2

JH - 2y-4

JF-8 a

HI - 3z-3,

Hence 2x+2 = 2y-4 = 3z-3 = 8

This means that

2x+2 = 8

2x = 8-2

2x = 6

x = 3

Also, 2y-4 = 8

2y = 8+4

2y = 12

y = 6

And 3z-3 = 8

3z = 8+3

3z = 11

z = 11/3

z = 3.67 ≈ 4

Hence x = 3, y = 6,z = 4

The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.

What is a slope?

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.

Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 3 - (-7) / ( -4 - 0 )
