Answer:

$1551 needed to cover the costs and 141 shirts will be sold.

Step-by-step explanation:

If a shirt costs $10 and the council is selling the shirt for $1 more ($11), after selling 141 shirts, they would have made a profit of $1*141=$141. Since there is also a setup fee of $141, the profit would actually be $0. This is when the costs are covered.

C = 10s + 141 (C is cost and s in no. of shirts sold)

s = 141

C = 141*10 + 141 = 1551

Answer:

Blank 1: 2

Blank 2: 7

Step-by-step explanation:

We can see that the starting value is 2, and the ratio is 7

The proportionality is 0.45, then the equation is C = 0.45 n. The number of peppers you buy for $20 will be 44.44. Then the table is completed below.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Let 'C' be the cost and 'n' be the number of peppers. Then the proportionality is given as,

C ∝ kn

At n = 5, the cost C = 2.25, then we have

2.25 = k (5)

k = 2.25 / 5

k = 0.45

Then the equation is given as,

C = 0.45 n

The number of peppers you buy for $20 will be given as,

20 = 0.45 n

n = 44.44

Then the table is completed below.

Number of peppers             Cost

              1                              $0.45

             2                              $0.90

             3                              $1.35

             4                              $1.80

             5                              $2.25

            10                              $4.50

            15                              $6.75

           20                              $9

          100                              $45

Answer:the number is 8

Step-by-step explanation:

Step 1

Let x be the number  13 was subtracted from so  that the difference becomes x-13

i.  dividing  the resulting difference by 5, then  (x-13)/5

ii.  Multiplying  the quotient by 7 makes  the expression become (x-13)/5 x 7

 with the product coming  to -7  we have our final equation as

(x-13)/5 x 7 = -7

Step 2 -----solving  the equation

(x-13)/5 x 7 = -7

Ist  divide  both sides by 7,

(x-13)/5 =-1

cross multiplying gives

x-13=-5

x= -5+ 13

x=8

the number is 8

Answer:

$45.57

Step-by-step explanation:

First, calculate the dollar amount of the tax. This can be done by multiplying the price by the sales tax percentage

$42 × 8.5%= $3.57

Now, add the sales tax amount back to the price.

42 + 3.57 = 45.57

Answer:

12 blue marbles

60 clear marbles

Step-by-step explanation:

From the information given:

Let the red marble be = r

the blue marble = b;  & the clear marbles be c

April has five times as many clear marbles as blue marbles.

i.e

5c as b

She has 4 times as many blue marbles as red marbles;

i.e.  4b as r

She has 3 red marbles

i.e. r = 3

If r = 3

Then; 4 times as many blue as r will be:

= 4 × 3

= 12 blue marbles

If b = 12; then 5 times as many clear marbles as blue marbles will be:

= 5 × 12

= 60 clear marbles

Answer: There is a strong positive correlation between Yumiko's exercise time and how far she runs.

Step-by-step explanation:

The correlation Coefficient value measures the relationship between two variables in other it determine the strength of association between them. The Coefficient could take any value between - 1 to + 1 with negative r values depiction negative relationships while positive values means positive relationship. The closer the r value is to either 1 or - 1, the stronger the relationship between hen m

Answer:

ab+bc+ca=0

Step-by-step explanation:

We are given:

[tex]x^a=y^b=z^c[/tex]

xyz=1

Separating equations:

[tex]x^a=z^c[/tex]

[tex]y^b=z^c[/tex]

Solving the first equation for x:

[tex]\displaystyle x=z^\frac{c}{a}[/tex]

Solving the second equation for y:

[tex]\displaystyle y=z^\frac{c}{b}[/tex]

Substituting in

xyz=1:

[tex]\displaystyle z^\frac{c}{a}z^\frac{c}{b}z=1[/tex]

Adding the exponents:

[tex]\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=1[/tex]

Since [tex]1=z^0[/tex]:

[tex]\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=z^0[/tex]

The base is z on both sides so we get rid of them:

[tex]\displaystyle \frac{c}{a}+\frac{c}{b}+1=0[/tex]

Multiplying by ab:

bc+ac+ab=0

Reordering:

ab+bc+ca=0

Step-by-step explanation:

Assuming i and j refer to the row and column of a given element, that matrix would be ...

  [tex]\left[\begin{array}{cc}2&3\\3&4\end{array}\right][/tex]

__

Rows are numbered top down, starting with 1. Columns are numbered left-to-right, starting with 1. The upper left element is in row 1, column 1, so has a value here of 1+1 = 2. Each number is one more than the one to its left. Each number is 1 more than the one above it.

Answer:

Step-by-step explanation:

The nth term of an exponential sequence is expressed as ar^n-1

The nth term of a linear sequence is expressed as Tn = a + (n-1)d

a is the first term

r is the common ratio

d is the common difference

n is the number of terms

Let the three consecutive terms  of an exponential sequence be a/r, a and ar

second term of a linear sequence = a +d

third term of a linear sequence = a + 2d

sixth term of a linear sequence = a + 5d

Now if the three consecutive terms  of an exponential sequence are  the second third and sixth terms  of a linear sequence, this is expressed as;

a/r = a + d ..... 1

a = a + 2d ..... 2

ar = a+ 5d .... 3

From 2: a = a + 2d

a-a= 2d

0 = 2d

d = 0/2

d = 0

Substitute d = 0 into equation 1:

From 1: a/r = a + d

a/r = a+0

a/r = a

Cross multiply

a = ar

a/a = r

1 = r

Rearrange

r = 1

Hence the common ratio of the exponential sequence is 1

Answer:

A general lineal equation is written as:

y = a*x +b

Where a is the slope (also called the rate of change) and b is the y-intercept-

For a line that passes through the points (x1, y1) and (x2, y2)

The slope will be:

a = (y2 - y1)/(x2 - x1)

For the line:

Y= (8/5)*x+ 3/5

The slope, or rate of change, is 8/5.

Then we want to find two points (x1, y1) and (x2, y2) such that the slope generated by them is larger to 8/5.

There are a lot of ways to finding these points, a simple way is:

We could define (x1, y1) = (0, 0)

And (x2, y2) = (5, 9)

Then the rate of change of the line that passes through these two points will be

a = (9 - 0)/(5 - 0) = 9/5

Which is larger than 8/5, as we wanted.

Answer:

a = 1

Step-by-step explanation:

[tex]\frac{2}{3} (9x - 3) = 2(3x - a)[/tex]

One must simplify this expression, by distributing. In order to find a solution, where x has infinite solutions, one must make this equation an identity. That means that the equation will hold true, no matter what value of x is plugged in.

[tex]\frac{2}{3} (9x - 3) = 2(3x - a)[/tex]

Distribute;

6x - 2 = 6x - 2a

Inverse operations;

6x - 2 = 6x - 2a

-6x        -6x

-2 = -2a

1 = a

For this equation to be true no matter what, a must equal 1.
