What is the total height of all the plants?

Answers

Answer 1

Answer: 6 1/8

Step-by-step explanation:

1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4

1/4 x 3 = 1/4 x 3/1 = 3/4

3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

5/8 x 1 = 5/8 x 1/1 = 5/8

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Start with the big number first.

1 1/2 = 1 4/8

5/8 = 5/8

3/4 = 6/8

1/4 = 2/8

Add them all up.

1 4/8 + 1 4/8 = 2 8/8 = 3

3 + 1 4/8 = 4 4/8

4 4/8 + 5/8 = 4 9/8 = 5 1/8

5 1/8 + 6/8 = 5 7/8

5 7/8 + 2/8 = 5 9/8 = 6 1/8

D) The median of 2nd Period is greater then the median of 1st Period.

Answers

It’s D) The median of 2nd period is greater then the median of 1st period

The correct statement is,

''The median of 2nd Period is greater than the median of 1st Period.''

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Mr. Kugler gave the same geometry test to his 1st and 2nd period classes.

And, The box and whisker plot summarizes the scores of each class.

Now, From figure;

The median of 2nd Period is,

⇒ 85

And, The median of 1st Period is,

⇒ 80

Thus, 80 < 85

Hence, The correct statement is,

''The median of 2nd Period is greater than the median of 1st Period.''

So the slope is (y2-y1)/(x2-x1)

(8-4)/(2-1)=
4/1 =
4

Aka. For every 1 week, the number of pictures taken increases by 4.

So it is 4 * w

Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16

help quick pls. Ms. Boi spent a total of $175.00 for 4 admission tickets and for parking at a baseball game. The cost of each admission ticket was the same amount, including tax. The cost of parking was $25. Write an equation that can be used to determine t, the cost, of each admission ticket, including tax.

Answers

Answer:

[tex]\frac{(175 - 25)}{4} = t[/tex]

Step-by-step explanation:

First, you should subtract the parking cost (25) from the overall cost (175) to find the admission unit pricing.

175 - 25 = 150

Divide the answer by 4, to find unit pricing (aka the cost of one ticket)

150/4 = 37.5

The cost of one ticket, including tax, is $37.50

The equation you need is

[tex]\frac{(175 - 25)}{4} = t[/tex]

hope this helps :)

The equation for cost of each ticket is t = ($175 -$25)/4, cost of ticket is $37.5.

What is equation?

Using the equals sign (=), an equation is a formula that expresses the equality of two expressions. The meanings of the word equation and its cognates in various languages can vary slightly. For instance, an equation in English is any well-formed formula consisting of two expressions coupled by an equals sign, while an equation in French is defined as including one or more variables.

Given total spent on 4 tickets and parking at a baseball game = $175.00

cost of parking = $25

cost of 4 tickets = $175 - $25

let cost of each ticket is t

t =($175 - $25)/4

cost of each ticket is $37.5

Hence the equation for ticket is t = ($175 -$25)/4, cost of ticket is $37.5.

the -5 inside the absolute value determines whether it is left or right, so we need to subtract five to move five to the right. Ok, so i'm pretty sure this is really confusing trust me i think it's correct

Each month, Margie's pets need 3 bags of dog food and 2 bags of cat food. How many bags of pet food would she need for 4 months?Which equation shows how to solve this problem?

Answers

Answer:

20 bags; 3 x 4 + 2 x 4 = y bags of pet food

Step-by-step explanation:

4 x 2 = 8 bags of cat food

4 x 3 = 12 bags of dog food

12 + 8 = 20 bags in total

So, we now know how many bags of pet food Margie needs for 4 months. To write an equation based on this, we need to include how many times Margie would buy each type of pet food. Which, in this case, would be 4 months. So, 4 months times 2 bags of cat food equals 8 bags of cat food, and 4 months times 3 bags of dog food equals 12 bags of dog food. This all together equals y amount of bags for pet food. In conclusion, 3 x 4 + 2 x 4 = y bags of pet food.

Answer:

20 bags of pet food in 4 months

Step-by-step explanation:

3*4=12

2*4=8

8+12=20

Dog food: Multiply 3 by 4 since 4 months which equals 12.

Cat food: Next multiply 2 by 4 since 2 bags in a month which equals 8

Finally add 8 and 12 and you will get 20 bags of pet food in 4 months.
