Answer:

a: [tex]40h+75f=800,h+f=13[/tex]

b: 5

c: 8

Step-by-step explanation:

Explanation for a: Making the equations

Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations [tex]40h+75f=800,h+f=13[/tex] since the total cost will be 800$, and we have a total of 13 ads.

Explanation for b: Solving for h

We can now solve for one of the variables using elimination. Let’s multiply the expression [tex]h+f=13[/tex] by -75.

[tex]-75h - 75f = -975[/tex]

Great! Now let’s add the equations.

[tex]40h + 75f = 800\\\\-75h - 75f = -975[/tex]

Adding these equations, we get

[tex]-35h = -175[/tex]

Divide both sides by -35, and we get [tex]h = 5[/tex].

Explanation for c: Solving for f

We can now substitute h inside the equation [tex]h + f = 13[/tex].

[tex]5 + f = 13\\\\f = 13-5\\\\f = 8[/tex]

Hope this helped!

(a) Let's say that h = half-page advertisement, and f = full-page advertisement.

Now It is given that there is a total of 13 advertisements present, and hence we have the first equation h + f = 13. Respectively we have the equation 40h + 75f = 800. This is represented by the following system of equations,

[tex]\begin{bmatrix}h+f=13\\ 40h+75f=800\end{bmatrix}[/tex]

(c) From here on let's solve this system for h and f. Isolating h in the first equation would give us h = 13 - f, which then can be substituted into the second equation to receive 40(13 - f) + 75f = 800. Let's solve for f --- (1)

40(13 - f) + 75f = 800,

520 - 40f + 75f = 800,

520 + 35f = 800,

35f = 280,

f = 280 / 35 = 8 full advertisements

(b) Now let's substitute this value of f back into the first equation to solve for the value of h --- (2)

h + 8 = 13,

h = 13 - 8 = 5 half advertisements

Answer:

Adult ticket= 7£

Child ticket= 2£

Step-by-step explanation:

Let the cost of an adult ticket be £A and the cost of a child ticket be £C.

2A +3C= 20 -----(1)

A +4C= 15 -----(2)

From (2):

A= 15 -4C -----(3)

Susbt. (3) into (1):

2(15 -4C) +3C= 20

30 -8C +3C= 20 (expand)

30 -5C= 20 (simplify)

5C= 30 -20

5C= 10

C= 10 ÷5

C= 2

Subst. C=2 into (3):

A= 15 -4(2)

A= 15 -8

A= 7

Thus, the cost of an adult ticket and a child ticket is 7£ and 2£ respectively.

Step-by-step explanation:

The sum to infinity of a geometric sequence is calculated as

Step-by-step explanation:

So, we know that Kelly read 19 books.

Elyse read 6 more books than 19.

Therefore, to find the amount of books Elyse read, add 6 to 19:

[tex]6+19[/tex]

Add:

Answer:

Friend is wrong

Step-by-step explanation:

Given:

friend's claim: height of his building is more than 1.50 times the height of yours

line of sight to the top edge of the other building makes an angle of 21° above the horizontal

line of sight to the base of the other building makes an angle of 52° below the horizontal

Solution:

Let A be the height of your building is A

Let B+A his building is B higher than yours.

Let the distance between the buildings is x.  

then

tan 52 = A/x

tan 21 = B/x  

A/B = tan 52 / tan 21

      =  1.27994 / 0.38386

A/B = 3.33

(A + B) / A = 1.5 0

A/A + B/A = 1.50

1 + B/A = 1.50

B/A is basically (B/x) / (A/x)

So

1+ 3.33 / 3.33

= 4.33/3.33

= 1.3

Since 1.3 is not equal to 1.5

Hence the friend's claim is wrong.

The height of the taller building can be given in relation to the height of

the other building using trigonometric ratios.

Correct response:

The given parameters are;

Angle of elevation to the top of the other building = 21°

Angle of depression to the base of the other building = 52°

The claim of the friend = The height of his building > 1.5 × The height of the other building

Required:

To state whether the claim is right or wrong.

Solution:

Let h represent the height of the smaller building, let l represent the

distance between the two buildings, and let d represent the height by

which one building is taller than the other, we have;

l·tan(21°) = d

l·tan(52°) = h

Height of the taller building, H = h + d = l·tan(52°) + l·tan(21°)

Height of the other building = h = l·tan(52°)

Therefore;

H ≈ 1.3·h

Which gives that the taller building, H, is approximately 1.3 times the other building.

Therefore;

Given

Required

Determine the slope of A'B'

Represent the coordinates of AB with (x,y), such that

[tex]AB = (x,y)[/tex]

Since A'B' is 3 * AB, we have

Answer:

Step-by-step explanation:

To find the length of the hypotenuse of QPO we must first find the value of x

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

QO² = QP² + OP²

That's

( x + 6)² = 5² + ( x + 5)²

x² + 12x + 36 = 25 + x² + 10x + 25

Group like terms

x² - x² + 12x - 10x = 50 - 36

2x = 14

Divide both sides by 2

x = 7

The hypotenuse of QPO is (x + 6)

Substitute the value of x into the expression

That's

The triangle is a right triangle.

We can use Pythagorean theorem to solve for the value of x.

[tex]OP^2 +PQ^2 =OQ^2[/tex]

[tex](x+5)^2 +5^2 =(x+6)^2[/tex]

Simplifying both sides.

Since Solise want to plant both trees and bushes in the same number of rows, you need to find the common factor.

Since the question is asking what the greatest number of rows she can plant, you have to find the greatest common factor.

The greatest common factor of 24 and 16 is 8.

You can plant 24 bushes in 8 rows (meaning you can divide it by 8), and 16 trees in 8 rows (meaning you can divide it by 8). Since the greatest number you can divide them both by is 8, the GCF of 24 and 16 is 8.

So the greatest number of rows Solise can plant is 8 rows.
