simplify the expression -3 divided by -2/5
a. -7 1/2
b. -1 1/5
c. 1 /15
d. 7 1/2

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

Answer:

p=-8/5

Step-by-step explanation:

-2p=3p+8

•take 3p to the left hand side

it becomes(-3p)

-5p÷(-5)=8÷(-5)

p=-8/5

The answer is 3x-x+2=4

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

you need to combine like terms

To help, the first step is to reorganize the expressions:

\(\frac{1}{3}x+\frac{1}{4} -\frac{2}{3}x\) is the same as \(\frac{1}{3}x-\frac{2}{3}x+\frac{1}{4}\), just in a different order.

Now, combine like terms:

\(\frac{1}{3}x-\frac{2}{3}x=-\frac{1}{3} x\\\frac{1}{4} =\frac{1}{4}\\\)

so

\(\frac{1}{3}x+\frac{1}{4} -\frac{2}{3}x=-\frac{1}{3}x+\frac{1}{4}\)

I did this to find the other ones as well, if you need me to explain those specifically I'd be happy to!

Answer:

42

Step-by-step explanation:

68 - 26 = 42

His mistake is that he does not open the bracket first. The value of the x is negative of 4.

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2.

First, open the bracket, then we have

\(\dfrac{x}{4} + \dfrac{12}{4} = 2\)

On simplifying, we have

\(\dfrac{x}{4 } + 3 = 2\)

Subtract 3 from both sides, we have

\(\dfrac{x}{4} = -1\)

Multiply the equation by 4, we have

\(x = -4\)

Answer:

  (a)  88 m

  (b)  74 cm

Step-by-step explanation:

You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.

The perimeter of a rectangle is given by the formula ...

  P = 2(L +W)

Filling in the given values, we can find the unknown.

  330 = 2(L +77)

  165 = L +77 . . . . . . . divide by 2

  165 -77 = 88 = L

The length of the garden is 88 meters.

The area of a rectangle is given by the formula ...

  A = LW

Filling in the given values, we can find the unknown.

  6734 = 91W

  6734/91 = 74 = W

The width of the window is 74 cm.

Because she bought a new hat for 22 dollars, subtract that from the 80 dollars.

1. 80-22=58

Next, each bow costs 5 dollars so you’ll have to see how many times 5 goes into 58 to get your answer.

2. 58/5= 11 with three dollars remaining.

That means Georgia can purchase 11 bows with the remaining money.

Answer: the answer is 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's start by finding the sum of the list of nine numbers, which we can then use to find the value of the remaining two numbers in the list:

Sum of the nine numbers = mean * number of numbers = 17 * 9 = 153

Let the three modes be a, b, and c. Since they are modes, each of them must appear at least twice in the list.

Let's assume that the numbers in the list are arranged in non-decreasing order. Then we have:

a ≤ b ≤ c

Since a, b, and c are modes, each of them must appear at least twice in the list. We have three cases to consider:

Case 1: Each of a, b, and c appears exactly twice in the list.

In this case, the remaining three numbers in the list are:

x1 = a + 4

x2 = b + 1

x3 = c - 8

We know that x1, x2, and x3 are distinct and not modes of the list. Therefore, they must be among the six numbers in the list that are not equal to a, b, or c. Let's call these numbers d, e, and f, where:

d ≤ e ≤ f

Then we have:

a + b + c + x1 + x2 + x3 + d + e + f = 153

3(a + b + c) + 3(d + e + f) = 153 + x1 + x2 + x3

Since x1, x2, and x3 are distinct and not modes of the list, we have:

x1 > c

x2 > b

x3 < c

Therefore, we can write:

x1 = c + k1

x2 = b + k2

x3 = a + k3

where k1, k2, and k3 are positive integers.

Substituting these expressions into the equation above, we get:

3(a + b + c) + 3(d + e + f) = 153 + a + b + c + k1 + k2 + k3

Simplifying, we get:

2(a + b + c) + 3(d + e + f) = 153 + k1 + k2 + k3

Since k1, k2, and k3 are positive integers, the right-hand side of this equation is at least 3. Therefore, we have:

2(a + b + c) + 3(d + e + f) ≥ 156

We want to find the value of 3(a + b + c), so let's isolate this term:

3(a + b + c) = 2(a + b + c) + (a + b + c)

Since the left-hand side is three times the sum of a, b, and c, and the right-hand side involves the sum of a, b, c, d, e, and f, we need to express d, e, and f in terms of a, b, and c.

From the inequality a ≤ b ≤ c, we have:

a + k3 ≤ b + k2 ≤ c + k1

Adding 4 to the first inequality, we get:

a + k3 + 4 ≤ b + k2 + 4 ≤ c + k1 + 4

Adding -8 to the second inequality, we get:

a + k3 + 4 ≤ c + k1 - 4 ≤ b + k2

Therefore, we can choose d = a + k3 + 4, e = c + k1 - 4, and f = b + k2. Then

Step-by-step explanation:

Its the only fraction that has 0.833333...

Answer:

5/6

Step-by-step explanation:

Using the relation between the sine and the cosine of an angle, it is found that:

\(\cos{\theta} = -\frac{2\sqrt{2}}{3}\)

The sine squared of an angle, plus the cosine squared of the same angle, is equals to one, hence:

\(\sin^2{\theta} + \cos^2{\theta} = 1\)

In this problem, we have that the sine is given by:

\(\sin{\theta} = -\frac{1}{3}\)

Hence:

\(\left(-\frac{1}{3}\right) + \cos^2{\theta} = 1\)

\(\cos^2{\theta} = 1 - \frac{1}{9}\)

\(\cos^2{\theta} = \frac{8}{9}\)

\(\cos{\theta} = \pm \sqrt{\frac{8}{9}}\)

\(\cos{\theta} = \pm \frac{2\sqrt{2}}{3}\)

We have that pi < theta < 1.5pi, hence the angle is in the third quadrant, where the cosine is negative, thus:

\(\cos{\theta} = -\frac{2\sqrt{2}}{3}\)
