Mathematics

Answer:

$120

Step-by-step explanation:

constant fee = (204-183) /(140-105)

= 21/35 = $0.6 per km

so, initial fee =

183 - (105 × 0.6)

= 183 - 63

= 120

Josie is making pizza dough. Complete the double number line by filling in the missing values

Answer:

n = \frac{4}{3}c

c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5

Step-by-step explanation:

Given

See attachment for complete question

Required

Complete the double number line

The given double number lines represent a linear function between cups of flour (c) and number of batched (n)

Pick any two pairs:

(c_1,n_1) = (\frac{3}{4},1)

(c_2,n_2) = (3\frac{3}{4},5)

First, calculate the rate of change (i.e. slope, m):

m = \frac{n_2 - n_1}{c_2 - c_1}

m = \frac{5-1}{3\frac{3}{4} - \frac{3}{4}}

m = \frac{4}{3}

So: the equation is:

n = m(c - c_1) + n_1

This gives:

n = \frac{4}{3}(c - \frac{3}{4}) + 1

n = \frac{4}{3}c - 1 + 1

n = \frac{4}{3}c

So, the above represents the relationship between n and c.

<u>To complete the table</u>

When n = 2

Substitute n = 2 in: n = \frac{4}{3}c

2 = \frac{4}{3}c

Make c the subject

c = \frac{3*2}{4}

c = \frac{3}{2}

When n = 3

Substitute n = 3 in: n = \frac{4}{3}c

3 = \frac{4}{3} * c

Make c the subject

c = \frac{3*3}{4}

c = \frac{9}{4}

When c=3

Substitute c=3 in: n = \frac{4}{3}c

n = \frac{4}{3} * 3

n = 4

So, the complete table is:

c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5

Help me with this please
ANEK [815]
The y-intercept appears to be at y=-1. The line appears to also go through grid point (3, 1), which is 2 units up and 3 units over. The slope is 2/3.

In slope-intercept form the equation of the line is
   y = (2/3)x - 1

Find the indicated length or angle measure (to the nearest tenth).
skad [1K]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Explain the formula to use

Using the cosine rule which states that:

z^2=x^2+y^2-2xy\cos Z

STEP 2: Write the given sides

x=4,y=6,Z=41^{\circ},z=?

STEP 3: Find the value of z

\begin{gathered} By\text{ substitution,} \\ z^2=4^2+6^2-2(4)(6)\cos41 \\ z^2=16+36-48cos41 \\ z^2=52-36.22605985 \\ z^2=15.77394015 \\ z=\sqrt{15.77394015} \\ z=3.971641997 \\ z\approx4.0 \end{gathered}

Hence, the indicated length is 4.0
