Answer:

Step-by-step explanation:

Answer:

F(t)= -4t+68

Thats all I can say :)

The equation showing the relationship between the Farenheit temperature (F) and time (t) is F = 4t + 68

A linear equation is given by:

y = mx + b

where y, x are variables, m is the rate of change, b is the initial vale of y (y intercept).

Let F represent the Fahrenheit temperature in t hours.

The temperature is falling outside at a steady rate of 4 degrees Fahrenheit every hour. Hence, m = 4.

The temperature starts at 68 Fahrenheit, hence b = 68. The equation becomes:

F = 4t + 68

Answer:

31.25 kg of flour is needed to make 50 cakes

Step-by-step explanation:

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?

We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.

Flour needed to make 4 cakes = 2.5 kg

Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg

Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]

                                                      = 31.25 kg

So, 31.25 kg of flour is needed to make 50 cakes

Answer:

Step-by-step explanation:

The cost of 3/4 of the chocolates is £40.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We are given that David buys 80 chocolate for £20 He sells 3/4 of the chocolates for 40p each

He then sells the remaning for 20p each.

Therefore,

80 chocolate = £20

one chocolate = 20/80 = £0.25

Then 3/4 of the chocolates = 40p

3/4 x 80 = 40p

60 = 40p

The remaning chocolates are;

80 - 60 = 20

Then 20 = 20p

p = 1

so, He sells 3/4 of the chocolates for £40.

Step-by-step explanation:

radius is half of diameter so you would just have to double the number.

t is 35 for  x+y= 7 and 7x + ty = 77, and the  value of t is 7 for x+y=7 and 7x+ty=49

Two or more expressions with an Equal sign is called as Equation.

Given equations are x+y= 7..(1)

7x + ty =77

We need to find value of t.

Multiply equation 1 with 7

7x+7y-7x-ty=49-77

y(7-t)=-28

7-t=-28

-t=-28-7

-t=-35

t=35

Hence the value of t is 35

Now for equations x+y=7

7x+ty=49

7x+7y-7x-ty=49-49

7y-ty=0

y(7-t)=0

7-t=0

t=7

Hence the value of t is 7

Therefore, t is 35 for  x+y= 7 and 7x + ty = 77, and the  value of t is 7 for x+y=7 and 7x+ty=49

Step-by-step explanation:

the slope always goes in front of the x and then the y-intercept goes after.

Answer:

First, let's explain the transformations in a general way:

Vertical shift.

If we have a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

This will move the graph of f(x) up or down a distance of N units.

if N is positive, then the shift is upwards

if N is negative, then the shift is downwards.

Horizontal shift.

If we have a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

This will move the graph of f(x) to the right or left a distance of N units.

if N is positive, then the shift is to the left

if N is negative, then the shift is to the right.

Horizontal dilation/contraction.

For a function f(x), an horizontal contraction dilation is written as:

g(x) = f(k*x)

where:

k is called the "scale factor"

If k < 1, then the graph "dilates" horizontally.

if k > 1, then the graph "contracts" horizontally.

Now, in this problem we have:

f(x) = log(x)

And the transformed function is:

g(x) = f(0.25*(x - 5)) + 3

Then, the transformations that take place here are, in order:

Vertical shift of 3 units up:

g(x) = f(x) + 3.

Horizontal shift of 5 units to the right:

g(x) = f(x - 5) + 3

Horizontal dilation of scale factor 0.25

g(x) = f( 0.25*(x - 5)) + 3

replacing f(x) by log(x) we have

g(x) = log(0.25*(x - 5)) + 3.

Answer:

DCB = 84

Step-by-step explanation:

Here, we want to calculate the value of the angle

To do this, we use an important parallelogram angle property

The adjacent sides are supplementary, meaning they add up to 180

We have this as;

180-96 = 84 degrees
