Andre sets up a rain gauge to measure rainfall in his backyard. On Tuesday, it rains off and on all day, use the graph to determine how much total rain fell on Tuesday

Answers

The total amount of rainfall is an illustration of the sum operator

The total amount of rainfall that fell on Tuesday is 35 mm

How to determine the total amount of rainfall?

From the graph (see attachment), we have the following function values

f(10) = 2

f(11) = 3

f(12) = 2

f(1) = 4

f(2) = 6

f(3) = 8

f(4) = 10

f(5) = 0

Add up the function values to determine thet total amount of rainfall

Total = 2 + 3 +2 + 4 + 6 + 8 + 10 + 0

Evaluate the sum

Total = 35

Hence, the total amount of rainfall that fell on Tuesday is 35 mm

Marley loves to draw and color. She bought 6 boxes of crayons. There are 8 crayons in each box. What is the total number of crayons Marley bought? What operation did you use to find your answer? Be sure to write your answer in a complete sentence.

Answers

Answer:

48 crayons

Step-by-step explanation:

There are 6 boxes total, each with 8 crayons in them. Notice that if you would count all the crayons, you would add 8 to the total number of crayons each time you counted a box. There are 6 boxes, so that would be equivalent to adding 8 a total of six times. You would use multiplication: 6 x 8 which is 48.

Answer:

marley has 48 crayons he bought

step by step equation:

6 times 8 =48

tina solved a quadratic equation and found the solution to be -3/2 and 6 which of the following is equivalent to the quadratic equations that tina solved

Answers

Answer:

[tex]x^2-\dfrac{9}{2}x-9=0[/tex]

Step-by-step explanation:

The solutions of a quadratic equation are :

x = -3/2 and x = 6

or we can write it as :

[tex]x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0[/tex]

Multiplying both values,

[tex](x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0[/tex]

Hence, the required quadratic equation is [tex]x^2-\dfrac{9}{2}x-9=0[/tex].
