A theater can seat 170 people. The number of rows is 7 less than the number of seats in each row. How many rows of seats are there?

Answers

Answer 1
Answer:number of rows =10
number of places in row = 17

Step-by-step explanation:
number of rows =N
number of places in row = N+7
N(N+7)=170
N^2+7n-170=0
(N+17)(N-10)=0
N1=-17
N2=10
We can`t take negative value for quantity of smth so we throw N1 away
From that number of rows =10
number of places in row = 10+7=17

alculate the area of the figure below using the following information:

Area of triangle ABC = 7.95 square units

Area of triangle ACD = 9.8 square units

Area of triangle AED = 8.75 square units

Image of irregular pentagon with vertices points A, B, C, D, and E starting at upper left moving clockwise. Two dotted diagonal lines, one connecting vertices A and C, and the second connecting vertices A and D.

The area of the Figure ABCDE is ______ square units

Answers

Answer:

26.5

Step-by-step explanation:

The areas of the three triangles given do not overlap. So the SUM (adding) of the three triangles is equal to the area of the pentagon.

Area of ABCDE

=ABC+ACD+AED

=7.95 + 9.8 + 8.75

What is the total price of a $6.89 item plus 6% sales tax?

Answers

$6.89 • 1.06 = $7.3034

OR

$6.89 • .06 = $0.4134
$6.89 + $0.4134 = $7.3034

$7.30 (rounded to the nearest hundredths) after sales tax

The total price of a $6.89 item plus 6% sales tax is $7.3043.

What is a percentage?

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of an item = $6.89

Sales tax = 6%

This means,

Sales tax amount.

= 6/100 x 6.89

= 0.4143

Now,

The total amount of the item.

= 6.89 + 0.4143

= $7.3043

Thus,

The total price plus 6% sales tax is $7.3043.

THE MATCH

There never was a time when the word was without fire, but there was a time when men did not know how to Kindle fire and after they teamed how to Kindle one, it was a long, long time before they learned how to kindle one easily
In these days we can kindle a fire without any trouble, because we can easily get a match, but we must remember that the match is one of the most wondertul things in the world, and that it took men thousands of years to kam how
to make one. Let us learn the history of this familiar e object, the match
Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set abtaze by a thunderbolt, we may say that nature strikes a match. In the eany history of the world,
nature had to kindle all the fires, for man by his own effort was unable to produce a spark The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by nature-by a volcano, perhaps, or by a stroke of
lightning These firebrands were carried to the home and used in kinding the fres there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would
sometimes be extinguished a sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.
In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, Chlorate of potash, and sulphid of antimony, and nutbed it on sandpaper, and it burst into fame. The druggist had discovered the first friction
chemical match the kind we use to-day. It is called friction chemical because it is made by miding certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless was not a
good one it could be lighted only by hard rubbing, and it sputtered and the in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now
Delighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub t. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the
match with which we are so familiar

Which does the author mean by nature had to knde as the fires, for man by his own effort was unable to produce a spark?

1. Humans were unable to make fire

2. Nature was unable to make fire

3. Humans were not very intelligent

4. Humans did not try to make fire

Solve the triangle, AMDM

Answers

Answer:

B

Step-by-step explanation:

You are given two sides and the included angle, so you need to use the law of cosines.

c² = a² + b² - 2ab cos C

c² = 12² + 13² - 2(12)(13)cos 134°

c² = 313 - 312(-0.6947)

c² = 529.733

c = 23.016

Now use the law of sines.

c/sin C = a/sin A

23.016/sin 134° = 12/sin A

sin A = 12 × sin 134° / 23.016

sin A = 0.37504

A = 22.03°

B = 180° - 134° - 22.03°

B = 23.97°

m<A = 22°; m<B = 24°; c = 23 km

Answer: B

Tanner is walking home from school, which is 9 blocks from his home. He walks 1 block per minute.
Write an equation that shows the relationship between the number of minutes Tanner has been walking, x, and the number of blocks he is from home, y.

Answers

Answer:

-x+9

Step-by-step explanation:

Here is the equation that shows the relationship between the number of minutes Tanner has been walking, x, and the number of blocks he is from home, y:

y = 9 - x

What type of equation is this?

This equation is a linear equation, and it can be interpreted as follows:

The number of blocks Tanner is from home is decreasing at a rate of 1 block per minute.

The y-intercept of the equation is 9, which represents the number of blocks Tanner is from home when he starts walking.

The slope of the equation is -1, which represents the rate at which Tanner is getting closer to home.
