Answer:

1.) Yes

2.)No

3.)Yes

4.)No

Step-by-step explanation:

1.) 12.5 - 8.4 = 4.1

4.1 x 7.4 = 30.34

7.4 x 4.1 = 30.34

2.)24 - 1.6 = 22.4

22.4 / 3.2 =7

6.4 / 3.2 = 2

7 does not equal 2

3.) 7.4 + 12.5 = 19.9

19.9 - 8.4 = 11.5

7.4 + 4.1 = 11.5

11.5 = 11.5

4.)8 x 2.5 = 20

20 - 3.2 = 16.8

20 + 4.1 = 24.1

24.1 does not equal 16.8

the daily low temperature readings for a five-day period were as followed -13, -5 ,6, -7, 9 find the average low temperature for

vivado [14]

First add the numbers together:
-13+(-5),6,(-7),9=-10
Then divide that number by the total # of numbers, which is 5
-10÷5=-2

The average low temperature is -2.

...which is 6th grade stuff, so I am having a hard time believing, that you are in college and/or are having problems with this.

Consider an isosceles trapezoid rotated about an axis of symmetry that passes through the midpoint of the bases. the minor base

Ronch [10]

Based on the calculation, the perimeter of the horizontal cross-section is equal to 36.13 cm.

<h3>How to calculate the perimeter?</h3>

In this scenario, the resulting geometrical shape formed when the cut is made at the middle of the height of the trapezoid and then rotated is a circle.

Given the following data:

Minor base = 10 cm.

Major base = 13 cm.

From the middle, the diameter of this circle is given by:

D = 1/2 (10 + 13)

D = 11.5 cm.

Now, we can calculate the perimeter:

Perimeter = πD

Perimeter = 3.142 × 11.5

Perimeter = 36.13 cm.

“Solve the equation. Determine if it is undefined or not.”

lozanna [386]

Answer: a) No Solution

b) Infinite Solutions (All Real Numbers)

Step-by-step explanation:

4(g + 8) = 7 + 4g

4g + 32 = 7 + 4g distributed 4 into g + 8

32 = 7 subtracted 4g from both sides

Since the statement is false because 32 ≠ 7, then there is NO SOLUTION

-4(-5h - 4) = 2(10h + 8)

20h + 16 = 20h + 16 distributed

16 = 16 subtracted 20h from both sides

Since the statement is true because 16 = 16, then there are INFINITE SOLUTIONS so x can be all real numbers.

You first,

Find the L. C. M, i hope u know the full name, if u don't, let me know in the comment section.
the L. C. M is 15
therefore it will be 10+3/15
