A stadium had a total of 19,000 seats. Of these seats 5,500 are field seats, and the rest are grandstand seats. Complete an equation that could be used to find s, the number of grandstand seats

Answers

Answer: The equation to find  Number of grand seats, s are either of the following

               x+ s= Total seats

                x+s= 19,000

                5000+s= 19,000

Number of grand seats, s= 14,000

Step-by-step explanation:

Step 1

A stadium had a total of 19,000 seats.

Given that  field seats=5,500

And the rest which are grandstand seats=?

Let field seats be represented  as x and grand seats be represented as s

such that the total  number of seats can be expressed as

x+ s = Total seats

x+ s=  19,000-------- Equation.

5000+s= 19,000

Step 2

Such that given field seats, x= 5000, Number of grand seats will  now be

x + s= 19,000

5000 + s= 19,000

s= 19,000-5000

=14,000 seats

Find g(x), where g(x) is the translation 7 units right of f(x)=x2. Write your answer in the form a(x–h)2+k, where a, h, and k are integers.

Answers

Answer:

[tex]g(x) =1(x + 7)^2 + 0[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2[/tex]

Required

Determine g(x) where g(x) is a translation of f(x), 7 units to the right

When a point is translated to the right, the resulting point is:

[tex]x -> x + b[/tex]

Where b is the number of units to the right.

In this case:

[tex]b = 7[/tex]

So, we have:

[tex]g(x) = f(x +7)[/tex]

Solving f(x+7)

Substitute x + 7 for x in [tex]f(x) = x^2[/tex]

[tex]f(x + 7) = (x+7)^2[/tex]

So, we have:

[tex]g(x) = (x+7)^2[/tex]

To write in the form of [tex]a(x - h)^2 + k[/tex], we have:

[tex]g(x) =1(x + 7)^2 + 0[/tex]

The height of Moyo and that of
Adamu differs by 9. The difference of the squares of their height is 120.
Find their heights.​

Answers

Answer:

The height of Moyo is

[tex]\frac{67}{6}[/tex]

The height of Adamu is

[tex]\frac{13}{6}[/tex]

Step-by-step explanation:

Equations

To solve the problem, we assign the variable:

x = height of Moyo

Since Moyo is 9 units taller than Adamu:

x - 9 = height of Adamu

The difference of the squares of their heights is 120, thus:

[tex]x^2-(x - 9)^2=120[/tex]

Operating:

[tex]x^2-(x^2-18x+81)=120[/tex]

[tex]x^2-x^2+18x-81=120[/tex]

Simplifying:

[tex]18x-81=120[/tex]

Adding 81:

[tex]18x=120+81=201[/tex]

Dividing by 18:

[tex]x=\frac{201}{18}=\frac{67}{6}[/tex]

The height of Moyo is

[tex]\frac{67}{6}[/tex]

The height of Adamu is

[tex]\frac{67}{6}-9=\frac{13}{6}[/tex]

What is the volume of this rectangular prism?

Answers

Answer:

1cm³

Step-by-step explanation:

You do not need a calculator for this.

The formula for the volume of a rectangular prism is:

Length × Width × Height = Volume

If we substitute our numbers in:

5/4 × 4/3 × 3/5 = 1cm³

All you need to do is multiply across.

5 × 4 × 3 = 60

4 × 3 × 5 = 60

The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.

60/60

Is the sequence below increasing or decreasing?
1/7 2/7 3/7 4/7 5/7

Answers

Answer:
Increasing

Explanation:
5/7 is bigger than 1/7

Answer:

Increasing

Step-by-step explanation:

Let us take a look, at these fractions in decimal forms.

1/7 = 0.14

2/7 = 0.28

3/7 = 0.42

4/7 = 0.57

5/7 = 0.71

From, these we can see that the value of the numbers keep increasing. So, the sequence above is increasing.

The 10th, 4th and 1st term of an A.P are three consecutive find the common ratio of the G.P and the sum of the 6th term, taking the 1st term to be 4

Answers

Answer:

Common ratio=1/2

Sum of first 6 terms of an A.P=31.5

Step-by-step explanation:

Let a be the first term and d be the common difference of an A.P

a=4

nth term of an A.P

[tex]a_n=a+(n-1)d[/tex]

Using the formula

[tex]a_4=a+3d=4+3d[/tex]

[tex]a_{10}=a+9d=4+9d[/tex]

According to question

We know that

For G.P

[tex]\frac{a_n}{a_{n-1}}=r[/tex]=Common ratio

[tex]r=\frac{4+3d}{4+9d}=\frac{4}{4+3d}[/tex]

[tex]\frac{4+3d}{4+9d}=\frac{4}{4+3d}[/tex]

[tex](4+3d)^2=\frac{4}{4+3d}[/tex]

[tex]16+9d^2+24d=16+36d[/tex]

[tex]9d^2+24d-36d-16+16=0[/tex]

[tex]9d^2-12d=0[/tex]

[tex]3d(3d-4)=0[/tex]

[tex]d=0, d=4/3[/tex]

Substitute the value of d

When d=0

[tex]r=\frac{4}{4+3d}=\frac{4}{4+0}=1[/tex]

When d=4/3

[tex]r=\frac{4}{4+3\times \frac{4}{3}}=\frac{1}{2}[/tex]

But we reject d=0 because  if we take d=0 then the terms are not consecutive terms of G.P

Sum of n terms of an A.P

[tex]S_n=\frac{n}{2}(2a+(n-1)d)[/tex]

Using the formula

Substitute n=6 and d=1/2

[tex]S_6=\frac{6}{2}(2(4)+5\times \frac{1}{2})[/tex]

[tex]S_6=31.5[/tex]

What is the total rental cost if Lashonda drove 30 miles?



need major help pleaseee this is functions

Answers

Answer:

$12.45

Step-by-step explanation:

To find the rental cost, plug in 30 as x

c(x) = 0.09x + 9.75

c(30) = 0.09(30) + 9.75

c(30) = 12.45

So, the total rental cost for 30 miles is $12.45

Answers

Answer: there u go this the correct answer if your on khan academy.

From the given right angle triangle, the length of side BC will be equal to 6√2.

What is a right angle triangle?

Any triangle that has one 90º angle has a right angle. Right triangles are those with an angle of 90 degrees, or "right angles," and are therefore those with this angle. The Pythagorean rule can be used to clarify the relationship between both the triangle's different sides.

As per the data provided in the question,

If one of the angles in a right triangle is 45 degrees, therefore the complimentary angle must also be 45 degrees.

Then,

m∠B = 45°

From the triangle ABC.

Cos B = BC/AB

As we know, the value of cos at 45° = √2/2

AB = 12

BC = cos (B) (AB)

BC = (√2/2) × 12 = 6√2 units.
