Max worked 6.23 hours on Monday, 7.45 hours on Tuesday, 8.3 hours on Wednesday, 8 hours on Thursday, and 5.21 hours on Friday. What is the total number of hours that Max worked?

Answers

Answer:

35.19

Step-by-step explanation:

6.23+7.45=13.68

13.68+8.3=21.98

21.98+8=29.98

29.98+5.21=35.19

Max worked for 35.19 hours which means Max most likely worked for 35 hours and 19 minutes. What you would do in this situation is add up all the hours Max has worked to find out how many TOTAL he has worked.

Answers

Answer:

I agree with you.

Step-by-step explanation:

I think you did this correctly. The correct process to solve this problem is something like this:

|x-c|=d

|x-c|=(6-(-4))/2 because d is the distance between the points / 2.

|x-c|=5

x-c=5, x-c=-5 (opening absolute value)

6-c=5, -4-c=-5

c=1

So:

|x-1|=5 is the correct answer.

The same value as 3.652 x 10⁻⁴ is 0.0003652.

What are the equivalent expressions?

Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given:

An expression, 3.652 x 10⁻⁴.

Simplifying,

3.652 x 10⁻⁴,

= 3.652 x 1/10000

= 0.0003652

Therefore, the value of the expression is 0.0003652.

find the area of the shaded triangle or quadrilateral.

Answers

Answer:

altogether its 42in(squared)

Step-by-step explanation:

Triangle:

1. 13-8=5

2. area of a triangle is 1/2 x l x b

3. Apply so 1/2 x 5 x 4 = 10in(Squared)

Quadrilateral:

1. 13-5=8

2. area of trapezium is (a+b)/2 x h

3. Apply so (8+8)/2 x 4

= 16/2 x 4

=8 x 4

=32in(squared)

Area of quatrilateral all together:

10+32=42in(squared)

The area of the shaded triangle or quadrilateral will be 42 square inches.

What is a trapezoid?

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.

The area of the trapezoid is half of the product of the height and the sum of the parallel sides. Then we have

Area = (1/2) x (Sum of parallel sides) x (Height)

A = (1/2) x (8 + 13) x 4

A = 2 x 21

A = 42 square inches

The area of the shaded triangle or quadrilateral will be 42 square inches.

A. The graph of this equation is a horizontal line.
B. The graph of this equation is a vertical line.
C. The graph of this equation is a slanted line.
D. The graph of this equation can be any straight line.

Answers

Answer:

D. The graph of this equation can be any straight line.

Step-by-step explanation:

Because A ≠ 0, it can be any number above or below 0.

Because B = 0, the line can only be a horizontal line. The line can be at any point on a graph, though, because A does not have any specific number that it equates to.

Answer:

40

Step-by-step explanation:

The given shape is made up of 4 equal right angled triangles.

Formula : -

Area of right angled triangle

= bh / 2

Here,

Base ( b ) = 5

Height ( h ) = 4

Area of each right angled triangle

= bh / 2

= ( 5 x 4 ) / 2

[ 4 = 2 x 2 ]

= ( 5 x 2 x 2 ) / 2

= 5 x 2

= 10

Area of 4 right angled triangles

= 4 x 10

= 40

Note : -

" □ " signify " right angle ".

the sides, based on the tickmarks on the picture, are all equal, so the figure is namely a rhombus with four congruent triangles, in this case each of the four triangles have a base of 4 and a height of 4, so

Hed been running for so long that he had pains in his side and his legs were beginning to hurt. He hunched over and tried to expand his lungs, but it was like trying to suck air out of a bicycle tire. His body was too exhausted to even allow him to take a deep breath, and he started to wheeze again.Great, he thought, let me just add asthma to my expanding list of ailments. I cant believe that I cant even jog two miles without completely collapsing! He finally gave in to his aching body and laid down on the grass to recuperate. He closed his eyes and tried to imagine himself running on the school track in the 1,600-meter race.

I am trying to get in shape to try out for track, but I cant even run two miles, he said dejectedly.Wait, how many months are you out of surgery? Didnt you just finish rehab last week? Meiya asked. You cant expect to run two miles the first day.It had been six months since Carlos surgery and he specifically remembered the doctor telling him he could start running after six months. But he thought about what Meiya had said and realized she had a good point. After his surgery, the doctor did say rehab would be crucial to his recovery but that it would take time for him to gain back full use of his leg. He thought about how a baby had to learn to walk before it could run. He remembered when his nephew was learning to crawl; within days it seemed like he was walking. Running didnt come right away, Carlo remembered. He realized it was the same with his therapy. The maximum he had run in the past month was one mile on the treadmill, so he realized that Meiya was probably right. He would have to work at building up his endurance and set more realistic goals for himself. As he thought about what he had already accomplished, he started to smile and felt like a weight was being lifted off his shoulders. He realized that he had run almost a mile and a half before his body started to protest and if he kept working hard, he could get back to where he was before his accident.Since when did you get so smart, Dr. Meiya? he teased.
