Tart & Sweet is a lemonade stand. Use the following bar chart to find Tart & Sweet's total profit from April to June.

Answers

Tart & Sweet's total profit from April to June is -$2.

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

Tart & Sweet is a lemonade stand.

From the following chart,

In April month,

the stand has profit of -$8.

In May month,

the stand has profit of $2.

In June month,

the stand has profit of $4.

To find the total profit from April to June:

Add all the profits,

-8+2+4

= -8 + 6

= -2

That means, the loss of $2 or profit of -$2.

Therefore, the profit of lemonade stand is -$2.

Step-by-step explanation:

well just add the blue which is 6 then add the red which is 8 then subtract them to get 2 and since negative is greater it will be -2

You buy 2 T-shirts in a sale. You pay the full price of $12 $12 for the first T-shirt, and you get the second T-shirt for half this price. What fraction of the full price do you pay for 2 shirts?

PLEASE HELP MEEE!!! MATH!! Write a similarity statement of the triangles. Which similarity postulate or theorem proves the triangles are similar? What are the congruent angles and/or proportional segments that justify the answer? PLEASE HELP!! picture is attached

Answers

Answer:

Step-by-step explanation:

1. The triangles are similar because the sides are proportional and they both hava a right angle.

2. It would be the hypotenuse leg theorem since they are right triangles.

3. The right angle justifies the triangles being similar.

Please help! Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which statement describes the properties of triangles ABC and A''B''C'' after the transformations?A) ∠C and ∠C'' are congruent after both the translation and the dilation.
B) ∠C and ∠C'' are congruent after the dilation, but not after the translation.
C) segment AC and segment A double prime C double prime are congruent after both the translation and the dilation.
D) segment AC and segment A double prime C double prime are congruent after the dilation, but not after the translation.

Answers

Answer:

A

Step-by-step explanation:

1) Translated figures are congruent ones, so \bigtriangleup ABC\cong \bigtriangleup A'B'C', one unit to the right and one up in comparison to \bigtriangleup ABC\cong \bigtriangleup ABC.

2)Since \bigtriangleup A''B''C''  was dilated with a scale factor of two then It's a similar figure to  \bigtriangleup ABC. Similar figures have congruent angles and different sizes.

Hence, ∠C≅∠C"

jim paddle from one shore of a lake three miles wide at 4 mph, and john paddles from the opposite shore at 5 mph. how long will they travel before they meet?

Answers

Let us assume that the distance travelled by Jim to meet John = X miles
Then the distance travelled by John to meet Jim = (3 - X) miles
We already know the equation
Time = Distance travelled/ Speed
Then for Jim,
Time = X/4
For John
Time = (3 - X)/5
As they meet, so they must have travelled the same amount of time.
Then
X/4 = (3 -X)/5
X = (12-4X)/5
5X = 12 - 4X
9X = 12
X = 12/9
  = 4/3
  = 1.33 miles
Now our target is to find the amount of time after which Jim and John meet.
 Then
Time = X/4
         = 1.33/4
          = 0.33325 hours
         = (0.33325 * 60) minutes
         = 19.995 minutes.
So it can be safely assumed that Jim and John will meet after a period of 20 minutes.
