a phone is 35 percent off which is now worth 78 pounds what was the original price

Answer:

1. 2x+4

2.2x-3

3.4x

4.3x-4

Answer:

l = (3x+5)

Step-by-step explanation:

Given that,

The area of a room, [tex]A=3x^2-x-10[/tex]

The width of the room, [tex]b=(x-2)[/tex]

We need to find the length of the room.

The area of the room is given by :

A = lb

[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^2-x-10}{x-2}\\\\l=\dfrac{(x-2)(3x+5)}{x-2}\\\\l=(3x+5)[/tex]

So, the length of the room is equal to (3x+5).

Answer:

[tex]d = 787.81cm^3[/tex]

Step-by-step explanation:

Given

See attachment for the containers

Required

The difference in the amount of snow cone they hold

The amount they hold is determined by calculating the volume of the containers.

The traditional snow cone has the following dimension

Shape: Cone

[tex]r=4cm[/tex] --- radius

[tex]h = 13cm[/tex] --- height

The volume is calculated as:

[tex]Volume = \frac{1}{3} \pi r^2h[/tex]

So, we have:

[tex]V_1 = \frac{1}{3} \pi * 4^2 * 13[/tex]

[tex]V_1 = \frac{208}{3} \pi[/tex]

The snow cone in a cup has the following dimension

Shape: Cylinder

[tex]r=8cm[/tex] --- radius

[tex]h = 5cm[/tex] --- height

The volume is calculated as:

[tex]Volume = \pi r^2h[/tex]

So, we have:

[tex]V_2 = \pi *8^2 * 5[/tex]

[tex]V_2 = \pi *320[/tex]

[tex]V_2 = 320\pi[/tex]

The difference (d) in the amount they hold is:

[tex]d = V_2 - V_1[/tex]

[tex]d = 320\pi - \frac{208\pi}{3}[/tex]

Take LCM

[tex]d = \frac{3*320\pi -208\pi}{3}[/tex]

[tex]d = \frac{960\pi -208\pi}{3}[/tex]

[tex]d = \frac{752\pi}{3}[/tex]

Take [tex]\pi = 22/7[/tex]

[tex]d = \frac{752}{3} * \frac{22}{7}[/tex]

[tex]d = \frac{752 * 22}{3*7}[/tex]

[tex]d = \frac{16544}{21}[/tex]

[tex]d = 787.81cm^3[/tex]

Answer:

A=250

r= 15%

Step-by-step explanation:

Given data

We have the function

y = 250(.85)^6------------1

The given function is the same as the exponential decrease

function

P=A(b)^t---------------------2

Note

b= 1-r= 1-0.15

b= 0.85

When we compare both 1 and 2 above

A=250

r= 15%

Answer: [tex]3^{9}[/tex]

Explanation:

When the base is the same and the terms are being divided, you subtract the exponents and leave the base as it is:

12 - 3 = 9

[tex]3^{9}[/tex]

Answer:

z = 10

Step-by-step explanation:

Distribute 2 to the terms in the parentheses:

2(2z + 5) = 50​

4z + 10 = 50

Subtract 10 from both sides

4z = 40

Divide each side by 4

z = 10

So, the answer is z = 10

Answer:

10

Step-by-step explanation:

1. Factorize left side.

2*2z+2*5=50

4z+10=50

2. Subtract 10 from both sides

4z=50-10

4z=40

3. Divide both sides by 4

z=40/4

z=10

Answer: x=1/2=0.5

Step-by-step explanation:

Given

3(2x) - 4(3x) + 3= 0

Expand parenthesis

6x - 12x + 3 = 0

Combine like terms

-6x + 3 = 0

Subtract 3 on both sides

-6x + 3 - 3 = 0 - 3

-6x = -3

Divide -6 on both sides

-6x / -6 = -3 / -6

x = 1/2 = 0.5

Hope this helps!! :)

Answer:

25

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

use the formula

√(x2 - x1)² + (y2 - y1)²

here x2 = -12 , x1 = 12 , y2 = -2 and y1 = 5

so just substitute in the formula like this

√ ( -12 -12)² + (-2 - 5)²

√(-24)² + (-7)²

√ 576 + 49

√625

17/10 is correct

Answer:

Yes.

Step-by-step explanation:

(10, -6) are the values to substitute in for x and y, respectively.

11(10) + 19(-6) = 110 - 114 = - 14

3(10) + 8(-6) = 30 - 48 = -18
