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]

Answer:

n+p=4.50

n=2p

2p+p=4.5

2p=4.5

p=$1.5

n=$3

Step-by-step explanation:

Answer:

Pencil: $1.50

Notebook: $3

Step-by-step explanation:

n = cost of notebook

p = cost of pencil

n + p = 4.5

n = 2p

substitute n into the first equation

2p + p = 4.5

3p = 4.5

p = 1.5

n = 2p

n = 2(1.5)

n = 3

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

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.

opposite angles in a parallelogram are equal to each other, so x = 146º

Answer:

option (3)

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = x² - 12x + 7

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 12x

f(x) = x² + 2(- 6)x + 36 - 36 + 7

      = (x - 6)² - 29

with vertex (h, k ) = (6, - 29 )

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]

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

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]

Because the Smith's ending amount is 21, and their beginning amount is 12 you subtract 21-12=9

Answer:

Well, there can be two answers. One of them can be 9, since they planted 9 MORE trees on top of the 12 already there. (21-12=9) The other answer can be 33 if you count all the trees they planted. (12+21=33)

Step-by-step explanation:

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
