In this question, we are to get the total number of hours that Irina used in watching the movie which does not include the term used for airing the commercials.

Now to calculate this, let us first take a look at the shaded segmented bar. We can see that out of the 6 horizontal bars, 5 were shaded. What this means is that 5/6 of the hours went into airing the movie while 1/6 of the hour went into airing commercials

Now, mathematically the number of hours she viewed the movie without the commercials can be calculated by adding all these 5/6 hour in the 3 hours

Mathematically that would be 5/6 + 5/6 + 5/6 = 3 (5/6) or simply 3 * 5/6 = 5/2 = 15/6 hours

Step-by-step explanation:

1)

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

2)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

3)

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

4)

P = 17b + 3

P = 17(6) + 3

Answers

Answer:

42 degrees (check attachements) hope it helps!

Step-by-step explanation:

Answer:

42

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary. We use that information and angles B and D to find the value of x. Then we use the value of x to find the measure of angle A.

m<B + m<D = 180

2x + 3x - 5 = 180

5x = 185

x = 37

m<A = x + 5

m<A = 37 + 5

m<A = 42

Interesting question

In a sale, the price of a sofa is reduced by 70%. The sale price is £255 What is the price before the sale?

Answers

So 255 is 30% of the original price
So what we need to do is divide 255 by 30 to get one percent
255/30=8.5
So 8.5 is one percent of the original price or one hundredth. So to get the original price multiply that by 100 and get 850.
The original price was £850.

Answer:

850

Step-by-step explanation:

Price x .30 (100%-70%)=sales price

price x .30 = 255

price = 255/.30

price = 850

The path of a projectile launched from a 26-ft-tall tower is modeled by the equation y = −16t2 + 64t + 26. What is the maximum height, in feet, reached by the projectile?

Answers

Answer:

The maximum height of the projectile is 90 ft

Step-by-step explanation:

Here, we want to get the maximum height reached by the projectile

The answer here will be the y-coordinate value of the vertex form of the given equation

so firstly, we have to write the equation in the vertex form

We have this as;

y = -16t^2 + 64t + 26

That will be;

y = a(x-h)^2 + k

y = -16(x-2)^2 + 90

where the vertex of the equation is;

(-h,k)

K

in this case is 90 and thus, that is the maximum height of the projectile

The correct option is (A)

We have to find that :

Which table shows exponential decay

From the figure of exponential decay :

When the value of one variable of the function is decreased with increase in the number of other variable, then it is called the exponential decay function with constant exponential coefficient.

It can be given as,

[tex]\frac{dN}{dt}=-\lambda N[/tex]

Here, [tex]\lambda[/tex] is the exponential coefficient.

From Option A:

x      y

1      16

2      8

3      4

4      2

The exponential coefficient for first and second row is,

[tex]\lambda=\frac{16}{8}=2[/tex]

Similarly,

[tex]\lambda=\frac{8}{4}=2\\\\\lambda=\frac{4}{2}=2[/tex]

Hence, as all the values of exponential coefficient is same, thus this shown the exponential decay.

From option B:

The exponential coefficient for first and second row is,

[tex]\lambda=\frac{16}{12}=\frac{4}{3}[/tex]

Similarly,

[tex]\lambda=\frac{12}{8}=\frac{3}{2} \\\\\lambda=\frac{8}{4}=2[/tex]
