Answer:

Step-by-step explanation:

When the balloons collide, they have the same x and y:

-3x^2 + 24x + 3 = y = -4x^2 + 25x + 15

Rearranging like terms together:

(4x^2 - 3x^2) + (24x - 25x) + (3 - 15) = 0

x^2 - x - 12 = 0

(x - 4)(x +3) = 0

x = 4 or -3

As x represents time, it cannot be negative.

The time when the balloons collide is at 4.00 seconds.

The collision means that y is equal

So

As it's time so must be positive

Answer:

The graph is compressed horizontally by a factor of 2, shifted left 3, reflected over the x-axis, and translated up 3.

Step-by-step explanation:

Answer:

The pyramid consists of 4 triangles having bases of 3 km and height of 4 km (measured along the face)

A = 4 * 3 / 2 * 4 = 24 km^2

Each triangle has an area of 1/2 * bottom length * height

3 cannot refer to the length of one of the isosceles triangles because a slant height of 4 km is given and is less than one such side

The surface area of the square pyramid is 24 km².

The surface area of a square pyramid with a slant height can be determined by the product of the base perimeter with the slant height divided by two.

Mathematically, it can be expressed as:

Surface Area S.A = P × l/2

where;

Surface Area (S.A) = 12 × (4/2)

Surface Area (S.A) = 24 km²

Answer:

g(x) = - 16x² + 4

Step-by-step explanation:

Given the model:

First drop:

h(x) = - 16x² + 64

Second drop hits the ground 1.5 seconds sooner

Function g(x) to model the second drop:

-16t² + V0t + h0

h(x) = - 16x² + 64

0 = - 16x² + 64

16x² = 64

x² = 64/16

x = 2

1.5 seconds sooner :

X = 2 - 1. 5

x = 0.5

0 = - 16(0.5)² + 0 + h0

0 = - 4 + h0

h0 = 4

Hence,

g(x) = - 16x² + 4

Answer:

$2.22

Step-by-step explanation:

First, we know that the cost of one mailing letter is $0.23 per once, plus $0.14.

Our formula is: c = 0.23w + 0.14

Let's rewrite our variables to the way it's suppsed to be.

C = cost

W = weight ounces.

Now, we have to add 0.23 plus 0.14 to get our cost.

That equals 0.37.

Now that we know that our cost for one letter is 0.37, we have to multiply

it by 6, because we are trying to figure out the cost of mailing a 6 ounce letter.

0.37 × 6 = 2.22

In conclusion, the cost of mailing a 6 ounce letter is $2.22

Answer:

$90

Step-by-step explanation:

We use the simple interest formula,

I = Prt

where

I = interest

P = principal amount = $500

r = interest rate = 6% = 0.06

t = time = 3 years

I = Prt

I = $500 × 0.06 × 3

I = $90

The relationship between the variables x, y and z is an illustration of similar triangles

The values of x, y and z are 6, [tex]\sqrt{117}[/tex] and [tex]\sqrt{52[/tex]

Right triangles are triangles with an angle measure of 90 degrees, and we have the following equivalent ratio from the triangle

[tex]x : 9 = 4 : x[/tex]

Express as fraction

[tex]\frac x9 = \frac 4x[/tex]

Cross multiply

[tex]x^2 = 36[/tex]

Take the square root of both sides

[tex]x = 6[/tex]

The value of y is then calculated using the following Pythagoras theorem

[tex]y = \sqrt{9^2 + x^2[/tex]

This gives

[tex]y = \sqrt{9^2 + 6^2[/tex]

[tex]y = \sqrt{117[/tex]

The value of z is then calculated using the following Pythagoras theorem

[tex]z = \sqrt{4^2 + x^2[/tex]

This gives

[tex]z = \sqrt{4^2 + 6^2[/tex]

[tex]z = \sqrt{52[/tex]

Hence, the values of x, y and z are 6, [tex]\sqrt{117}[/tex] and [tex]\sqrt{52[/tex]

Loss=Rs 80

Loss%=4%

Step-by-step explanation:

Cost price of trousers for Ujeli=Rs2000

Marked price for trousers =Rs 2400

Reduction of MP(take it as discounted) =20%

Selling price=MP-20%of MP=2400 - 20/100 * 2400 = 2400 - 480 = Rs 1920

Loss amount =CP - SP = 2000 - 1920 = Rs 80

Loss% =loss amt/CP *100 =80 / 2000 *100 =4%

Divde each side by -4

x < -10 / -4

Dividing each side by a negative number flips the inequality

x > - 10 / -4

- 10 / -4 = 10 / 4 = 5/2

x > 5/2

She will receive 22% commission

Step-by-step explanation:

18% commission when the profit on a car is under $400

22% when the profit is at least $400 and less than $1,000

24% when the profit is $1,000 or more.

How much will she receive if she sold $800 in profits?

She will receive 22% commission

$800 profits is greater than $400 but less than $1000

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

[tex]4T + 7F = 38.3[/tex]

[tex]5T + 5F = 40.75[/tex]

Required

Determine the values of T and F

[tex]5T + 5F = 40.75[/tex]

Divide through by 5

[tex]T + F = 8.15[/tex]

Make F the subject

[tex]F = 8.15 - T[/tex]

Substitute 8.15 - T for F in the first equation

[tex]4T + 7F = 38.3[/tex]

[tex]4T + 7(8.15 - T) = 38.30[/tex]

[tex]4T + 57.05 - 7T = 38.30[/tex]

Collect Like Terms

[tex]4T - 7T = 38.30 - 57.05[/tex]

[tex]-3T = -18.75[/tex]

Solve for T

[tex]T = -18.75/-3[/tex]

[tex]T = 6.25[/tex]

Recall that:

[tex]F = 8.15 - T[/tex]

[tex]F = 8.15 - 6.25[/tex]

[tex]F = 1.90[/tex]

Step-by-step explanation:

You want to identify the expressions equivalent to 11x -4x +6x and 3(1 +9y).

We can identify the equivalent expressions by putting them all in their simplest form. This means using the distributive property to eliminate parentheses, and combining like terms.

The simplified version of the given expression is ...

  (11 -4 +6)x = 13x

The other expressions simplify to ...

  7x +6x = (7+6)x = 13x . . . equivalent

  7x -6x = (7 -6)x = 1x = x . . . not equivalent

  13 +x (already simplest) . . . not equivalent

  13x (already simplest) . . . equivalent

The simplified form of the given expression is ...

  3·1 +3·9y = 3 + 27y

The other expressions simplify to ...

  3 +1·3 +9y = 6 +9y . . . not equivalent

  3 +27y . . . equivalent

  3·1 +3·9y = 3 + 27y . . . equivalent

  3 +9y (already simplest) . . . not equivalent

Step-by-step explanation:

just add all the given angles and equate it with 540° and then find x

x/2 + x/2 + x - 25 + 100 + x - 15 = 540°

3x + 60 = 540°

3x = 540 - 60

x = 480/3

x = 160°

on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.
