Complete question :

There are 575 fireworks to be shot off in a firework display every minute 12 new fireworks are shot off display write a verbal model and algebraic expression to represent the number of fireworks left to be shot off after t minutes.

Answer:

575 - 12t

Step-by-step explanation:

Given the following :

Total number of fireworks = 575

Number of shots per minute = 12

To calculate the number of fireworks left to be shot off after t minutes, The total number of fireworks already shot after the same time interval t in minutes, is first obtained, this is equivalent to (12*t). The result is then subtracted from the total number of fireworks to be shof off.

In algebraic terms

[total number of fireworks on display - (number of shots per minute × t)]

575 - 12t

Answer:

44m

Step-by-step explanation:

A = [tex]\pi[/tex]r² = 154

   = 22/7 * r² = 154

   = r²  = 154 * 7/22

   = r²  = 49

   = r = √49

   = r = 7m

Perimeter of circle = 2[tex]\pi[/tex]r

                               = 2 * 22/7 * 7

                               = 44/7 * 7

                               = 44 m

Answer:

44m

Step-by-step explanation:

Area of circular field=154m²

Perimeter of the field=?

At first,

Area =22/7×r²

154m²= 22/7×r²

154×7/22=r²

49=r²

7×7=r²

7=r

Now,

Perimeter = 2×22/7×7

= 44m

Answer:

The width is 4

Step-by-step explanation:

since the area is 36

9 times x = 36

so

since 9 x 4 = 36,

the width is 4

Answer:

a)  08:04

b)  07:00

c)  14 minutes

Step-by-step explanation:

a)  According to the timetable, a bus that leaves at 07:54 from Hope Street will arrive at School Rock at 08:04.

b)  Since Jo needs to be at the school at 8 am, she can't arrive at a time that is past 8.  This means that the latest time to catch the bus station is 07:00.

c)  You have to subtract the time at which you reach the destination by the time at which you leave your starting time.  It takes the bus 14 minutes to travel from the bus station to School Road.

07:14 - 07:00 = 00:14

Explanation:

When we reflect over the vertical y axis, every negative x value becomes positive and vice versa. So we effectively replace x with -x like so

f(x) = -5x+9

f(-x) = -5(-x)+9 ... replace every x with -x

f(-x) = 5x+9

g(x) = 5x+9

A point like (1,4) on f(x) will reflect over to (-1,4) on g(x). If we apply this to every point on f(x), then all of f(x) will reflect to g(x).

Answer:

[tex]\Huge \boxed{{9}}[/tex]

Step-by-step explanation:

Let the age of Darrell be x.

Let the age of Bryce be y.

x = y + 8

xy = 153

Substitute x = y + 8 in the second equation.

(y+8)y = 153

Solve for y.

y² + 8y = 153

Subtract 153 from both sides.

y² + 8y - 153 = 0

Factor left side.

(y-9)(y+17) = 0

Set factors equal to 0.

y - 9 = 0, y = 9

y + 17 = 0, y = -17

The value of y has to be positive, so y = 9.

Substitute y = 9 in the first equation.

x = 9 + 8

x = 17

Darrell is 17 years old.

Bryce is 9 years old.

Answer:

[tex]\huge\boxed{9\ years}[/tex]

Step-by-step explanation:

Let Darrel's Age be x and Bryce's Age be y

Condition 1:

x = 8 + y

Condition 2:

xy = 153

Put the 1st equation in the second one

(8+y)y = 153

y²+8y-153 = 0

y²+17y-9y-153 = 0

y(y+17)-9(y+17) = 0

(y-9)(y+17) = 0

Either,

y-9 = 0   OR    y+17 = 0

y = 9       OR    y = -17 [Contrary to be given, Age can never be negative]

So, y = 9

And

Bryce's Age = 9 years

[tex]\huge \boxed{b=2}[/tex]

Step-by-step explanation:

[tex]5(2- b) = 0[/tex]

[tex]\sf Divide \ both \ sides \ by \ 5.[/tex]

[tex]2-b=0[/tex]

[tex]\sf Subtract \ 2 \ from \ both \ sides.[/tex]

[tex]-b=-2[/tex]

[tex]\sf Cancel \ negative \ signs.[/tex]

[tex]b=2[/tex]

Answer:

b = 2

Step-by-step explanation:

5(2-b) = 0

=> 5 x 2 - 5 x b = 0

=> 10 - 5b = 0

=> -5b = -10

=> -b = -10/5

=> -b = -2

=> b = 2

Let's check whether our answer is correct:

=> 5(2-2) = 0

=> 5 (0) = 0

=> 0 = 0

he needs to run 0.75 miles = 3 laps

The fact that Leslie used a dilation is where she made the mistake. A dilation either shrinks or enlarges a figure. So it made segment ST either larger or smaller to be able to fit to segment QR.

But congruent segments are always the same length. So there's no way that a dilation can be involved. Only rigid transformations of translations (aka shifting), reflections, and rotations are allowed. A dilation is not a rigid transformation.

Answer:

930 dollars

Step-by-step explanation:

Let software programs = S

Video game = V

Given that a company makes a profit of $7 per software program that is, 7S and $8 per video game that is, 8V. The company can produce at most 90 software programs and at most 80 video games per week. Since the Total production cannot exceed 120 items per week.

How many items of each kind should be produced per week in order to maximize the profit?

The to get profit P

P = 7S + 8V

Since the profit on video game is higher, we will give maximum production to video game. Therefore,

P = (30 × 7) + ( 8 × 90)

P = 210 + 720

P = 930 dollars

Answer:

see below

Step-by-step explanation:

tan ^2 x -sin ^2 x = tan ^2x sin ^2x

tan = sin / cos

sin ^2 x / cos ^2 x -sin ^2 x = sin ^2 x / cos ^2 x * sin^2 x

Multiply each side by cos ^2

cos ^ x (sin ^2 x / cos ^2 x -sin ^2 x) = cos ^2 x(sin ^2 x / cos ^2 x * sin ^2x)

sin ^2 x  - cos ^2 x sin ^2 x = sin ^2 x  * sin ^2x

Factor out sin ^2 x

sin ^2 x(1  - cos ^2 x) = sin ^2 x  * sin^2 x

We know that 1 - cos ^2 x = sin ^2 x

sin ^2 x(sin ^2 x) = sin ^2 x  * sin^2 x
