Answer:

part A) $f=2.75p$

par B) $38.5\ cups\ of\ flour$

Step-by-step explanation:

Part A)

Let

p ----> the number of pounds of cake

f ----> the number of cups of flour

we know that

A relationship between two variables, p, and f, represent a proportional variation if it can be expressed in the form $k=\frac{f}{p}$ or $f=kp$

Find the value of k

For p=3, f=8.25 ----> $k=\frac{8.25}{3}=2.75$

therefore

The linear equation is

$f=2.75p$

Part B) we have

For p=14

substitute in the equation and solve for f

$f=2.75(14)=38.5\ cups$

Sarah earns a 5% commission for each house she sales. Write an equation that relates Sarah's total incomes (T), if she has a bas

jonny [76]

Answer:

$T = 25000 + 0.05x$

Step-by-step explanation:

Given

$Salary = 25000$

$Commission = 5\%$

Required

Write an equation when sales = x

The equation can be written as:

$Total (T) = Salary + Commission * Sales$

This gives

$T = 25000 + 5\% * x$

Convert percentage to decimal

$T = 25000 + 0.05 * x$

$T = 25000 + 0.05x$

Find the value of log(4) ∙ log(25) to five decimal places.

Fittoniya [83]

Answer:0.84164

Step-by-step explanation:

Given

$\log \left ( 4\right )\cdot \log \left ( 25\right )$

we know

$\log a^b=b\log a$

Applying this identity we get

$\log \left ( 2\right )^2\cdot \log \left ( 5\right )^2$

$=2\log \left ( 2\right )\times 2\log \left ( 5\right )$

$=4\times \log \left ( 2\right )\cdot \left ( 5\right )$

$=4\times 0.301029\times 0.698970$

$=0.84164$

What is the midpoint of the line segment graphed below?<br><br> (-12, 3) (5, -10)

Colt1911 [192]

Use the midpoint formula

(x1 + x2/2, y1 + y2/2)

Input the corresponding numbers

(-12 +5/2, 3 + -10/2)

(-7/2,-7/2)

So, the midpoint of the line segment is (-7/2,-7/2)
