Answer:

Christine has completed 35% of her total deliveries.

Step-by-step explanation:

To find the answer, you can use a rule of three considering that as Christine needs to make a total of 40 deliveries this week, this would represent 100% and with this you can find the percentage that the 14 deliveries completed represent:

40 → 100%

14  →    x

x=(14*100)/40=35%

According to this, the answer is that Christine has completed 35% of her total deliveries.

  see below

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: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

Step-by-step explanation:

Triangles ABX and DCX are similar.

Since they are similar, AX/DX = AB/DC.

Hence AX/2.8 = 8/4 and AX = 5.6.

Answer:

[tex]x = \frac{ - 3}{2} \: or \: \frac{1}{3} [/tex]

Step-by-step explanation:

[tex]7 {x}^{2} + 10x - 3 = {x}^{2} + 3x[/tex]

[tex] = > 7 {x}^{2} - {x}^{2} + 10x - 3x -3 = 0[/tex]

[tex] = > 6 {x}^{2} + 7x - 3 = 0[/tex]

[tex] = > 6 {x}^{2} + 9x - 2x - 3 = 0[/tex]

[tex] = > 3x(2x + 3) - 1(2x + 3) = 0[/tex]

[tex] = > (2x + 3)(3x - 1) = 0[/tex]

Here x will have 2 values.

1) [tex]2x + 3 = 0[/tex]

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:

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.

Answer:

1

Step-by-step explanation:

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:

  [-6, 8]

Step-by-step explanation:

The range of a function is its vertical extent.

Here, the low point on the graph is (11, -6). The high point on the graph is (-6, 8). The graph is continuous between these points, so every value between a low of y=-6 and a high of y=8 is part of the range:

  -6 ≤ y ≤ 8 . . . . . . . . [-6, 8] in interval notation

Answer:

a. Geometric

b. 20, 10 and 5

c. Tn = 20(0.5)^n-1

d. 0.00004 ft

Step-by-step explanation:

a. The sequence is geometric

The reason for this is that we will be multiplying each term by a particular value

If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number

b. 1st term is

20

second term

1/2 * 20 = 10

Third term

1/2 * 10 = 5

c. Explicit formula

Mathematically, that will be;

Tn = ar^n-1

Where r is 1/2 or 0.5

Tn = a(0.5)^n-1

where Tn is the present term and n is the present number of the term

d. 20th term

T20 = 20 * 0.5^19

T20 = 0.00004 ft

Answer:

The area of the rectangle is 22 m^2. The perimeter of the rectangle is 19.93

Step-by-step explanation:

The area of a rectangle is [tex]l*w[/tex]. The perimeter of a rectangle is [tex]2(l+w)[/tex] or just adding up all 4 sides. Now, all you need to do is math.

[tex]A= 3.3 * (20/3) = 22\\P = 2 (3.3 + (20/3)) = 19.93[/tex]

Answer:

I will consider $18/hour pay

Step-by-step explanation:

Before we an know which of the money to consider, we need to converted the equivalent amount in years

If $18 dollars is offered per hour, to know the equivalent amount per year.

1year = 8760hour

$18 = 1hr

x = 8760hr

x =18×8760

x = $157680

For the monthly pay

$3000 = 1month

y =12months

Since 12months are in year

Cross multiply

y = 3000×12

y = $36000

Since the hourly pay equivalent in years is greater than the monthly and yearly pay, hence I would consider $18 per hour pay

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:

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

Answer:

14x-21y

Step-by-step explanation:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. This is:

  7(2x – 3y)

= 7(2(6) – 3(-2))

= 7(12 + 6)

= 7(18)

Answer:

Step-by-step explanation:

Given the decimal number

[tex]6.05[/tex]

Rewrite as

[tex]=6+0.05[/tex]

[tex]=6+\frac{5}{100}[/tex]        ∵ 0.05 = 5/100

[tex]=6+\frac{1}{20}[/tex]

[tex]=\:\frac{121}{20}[/tex]

[tex]=6\frac{1}{20}[/tex]

Given the decimal number

12.346

Rewrite as

[tex]=12+0.346[/tex]

[tex]=12+\frac{173}{500}[/tex]              ∵ 0.346 = 346/1000 = 173/500

[tex]=12\frac{173}{500}[/tex]

Given the decimal number

7.5

Rewrite as

[tex]=7+0.5[/tex]

[tex]=7+\frac{1}{2}[/tex]                 ∵ 0.5 = 1/2

[tex]=7\frac{1}{2}[/tex]

Answer:

The original amount of muffin she original made will be: m = 49

Step-by-step explanation:

Given that after selling 28 muffins, 21 muffins remained.

Thus, the equation becomes

[tex]m - 28 = 21[/tex]

adding 28 to both sides

[tex]m-28+28 = 21+28[/tex]

[tex]m = 49[/tex]

Therefore, we conclude that the original amount of muffin she original made will be: m = 49
