Answer:

t = 0.75n - 0.25

t represents your total

Step-by-step explanation:

So lets start by writing our total variable.

t =

Now each candy is 0.75 so lets write that down too.

t = 0.75

Since we don't know how much candy we buy, lets multiply 0.75 by n.

t = 0.75n

Now we have a $0.25 coupon so now subtract the 0.25 from the cost.

t = 0.75n - 0.25

There you go.

Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Je
ratelena [41]

The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method

The given equation is  \frac{x}{3} + 8 = -2

<u><em>Solving the equation using </em></u><u><em>Natasha's</em></u><u><em> method </em></u>

the fist step is to multiply by 2

x + 24 = - 6

The second step is to combine  and add similar terms

x = -24 - 6

x = -30

<u><em /></u>

<u><em>Second method of solving the equation</em></u>

The equation the friends are trying to solve is \frac{x}{3} + 8 = -2

The first step is to combine similar terms

\frac{x}{3} = - 8 - 2

The second step is to add similar terms together

\frac{x}{3} = - 10

The third step is to multiply both sides of the equation by 3

x = (-10 x 3)

x = -30

The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answ
bazaltina [42]

Answer:

The images of the question are missing, I found a matching question and image online, and it is in the attachments.

Answer:

The scale factor of the triangles from the left to the right is 2

or

The scale factor of the triangles from the right to the left is 1/2

Step-by-step explanation:

From the image, the right triangle on the left has the following dimensions:

Hypotenuse = 10

length of one side = 10

While the right triangle on the right has the following:

Hypotenuse = 20

Length of one side = 20

From the dimensions above it can be seen that the triangle on the right has a dimension of 2 times the triangle on the left:

Left (10)  × 2 = right (20)

Therefore the scale factor of the triangles from the left to the right is 2

or

The scale factor of the triangles from the right to the left is 1/2

A water tank has a square base of area 5 square meters. Initially the tank contains 70 cubic meters. Water leaves the tank, star
ANEK [815]

Answer:

9.2\ \text{m}

Step-by-step explanation:

b = Surface area of base = 5 square meters

Volume of water in tank = 70 cubic meters

The rate at which the volume is reducing is

\dfrac{dV}{dt}=2+4t\\\Rightarrow dV=2+4tdt

Integrating from t=0 to t=3

V=\int^3_0(2+4t)dt\\\Rightarrow V=2t+2t^2|_0^3\\\Rightarrow V=2\times 3+2\times 3^2-0\\\Rightarrow V=24

Volume of water remaining in the tank is 70-24=46\ \text{m}^3

Suface area of base \times depth = Volume

5\times d=46\\\Rightarrow d=\dfrac{46}{5}\\\Rightarrow d=9.2\ \text{m}

The depth of the water remaining in the tank is 9.2\ \text{m}.
