slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (5, 9) and (x₂, y₂ ) = (3, 9)

m = [tex]\frac{9-9}{3-5}[/tex] = [tex]\frac{0}{-2}[/tex] = 0

4x+3150-6x=2876

-2x=-274

x=137

y=525-137

y=388

Hence, about 137 childern tickets were sold and 388 gernal admission tickets were sold.

Paul.

The solution of the given situation is that about 137 childern tickets were sold and 388 admission tickets were sold.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that school is selling tickets to their Spring theater production Student tickets cost $6 each and non-student tickets cost $9 each There are a total of 250 seats available in the auditorium.

Let s represent the number of student tickets sold and let n represent the number of non-student tickets sold then the equation is;

4x+3150-6x=2876

-2x=-274

x=137

Now,

y=525-137

y=388

Hence, about 137 childern tickets were sold and 388 admission tickets were sold.

Answer:

Area of park = 650m ²

Cost of setting blocks = Rs.24,700

Step-by-step explanation:

Given:

Length of park L = 26 m

Width of park B = 25 m

Find:

Area

Cost of Paving = 38 per m square

Computation:

Area of park = L x B

Area of park = 25 x 26

Area of park = 650m ²

Cost of setting blocks = Area of park x 38

Cost of setting blocks = 650 x 38

Cost of setting blocks = Rs.24,700

Answer:

It would be 90 miles/2, it's rate is 45 miles per hour

Answer:

90 miles/2 hours

Step-by-step explanation:

180/8 = 22.2mph

240/6 = 40mph

90/2 = 45 mph

30/1 = 30 mph

45 mph is faster than every other unit rate, therefore 90 miles/2 hours  is the fastest.

I believe it's 19u+72

Step-by-step explanation:

Hope this helps! ^^

Answer:

(u + 8)(u + 9)

Step-by-step explanation:

Assuming you require to factorise the expression

u² + 17u + 72

Consider the factors of the constant term (+ 72) which sum to give the coefficient of the u- term (+ 17)

The factors are + 8 and + 9, since

8 × 9 = 72 and 8 + 9 = 17, then

u² + 17u + 72 = (u + 8)(u + 9) ← in factored form

Answer: Loss percent = 0.775%

Step-by-step explanation:

Here,

Total cost = Purchasing price + transportation

⇒ Total cost = 6375 + 75

⇒ Total cost = $ 6450

Selling price = $ 6400

Total cost > Selling price, hence it is a loss.

Loss percent formula :

[tex]Loss\% =\dfrac{\text{Loss}}{Total\ cost}\times100\\\\=\dfrac{Total\ cost - Selling price}{Total \ cost}\times100\\\\=\dfrac{6450-6400}{6450}\times100\\\\=\dfrac{50}{6450}\times100=0.775\%[/tex]

Hence, Loss percent = 0.775%

Answer:

The answer for (-1/2)^4 is 1/16

Step-by-step explanation:

Given

No. of employees [tex]N(t)=500(0.02)^{0.7^{t}}[/tex]

(a)When the company opens i.e. at t=0

[tex]N(0)=500(0.02)^{1}=10[/tex]

There are 10 employees at the beginning

(b)when N=100

[tex]100=500(0.02)^{0.7^{t}}\\0.2=0.02^{0.7^{t}}[/tex]

Taking log both sides

[tex]\ln (0.2)=0.7^t \cdot \ln (0.02)[/tex]

[tex]0.7^t=\frac{\ln (0.2)}{\ln (0.02)}=0.4114[/tex]

again taking log

[tex]t\times \ln (0.7)=\ln (0.4114)[/tex]

[tex]t=\dfrac{\ln (0.4114)}{\ln (0.7)}=2.49[/tex]

(c)when t tends to [tex]\infty[/tex], [tex](0.7)^t\rightarrow 0[/tex]

So, [tex]N(\infty)=500\cdot(0.02)^0=500\times1=500[/tex]

i.e. there can be 500 employees at max

Answer:

10

Step-by-step explanation:

We will first take a right triangle and we will apply the pythagorean theorem to it. First, the base of the right triangle will be 12/2 which is 6; then, we will just use the theorem.

a^2+b^2 = c^2 (pythagorean theorem)

8^2+6^2 = c^2

100 = c^2

c = 10 because the square root of 100 is 10
