A flower shop normally orders 18 3/5 pounds of roses each week. The shop is planning on ordering four times as much during the week of Valentine's Day. For how many pounds of roses should the order be?

Answer:

Interest = $60.75

Amount = $510.75

Step-by-step explanation:

The formula for finding interest is;

Interest = Principal * Rate * Time

And here;

Principal = $450

Rate = 41/2% or 4.5%

Time = 3 years

Interest = [tex]\frac{450 * 45 * 3}{1000}[/tex]

Divided by 100 because of the percentage of the rate but here I made it 1000 because I moved the decimal point in the 4.5 forward once which means I have to add 0 to the denominator.

              = [tex]\frac{45*45*3}{100}[/tex]

             = [tex]\frac{6075}{100}[/tex]

            = $60.75

Now the amount is simply the Principal + Interest which will be;

= $450 + $60.75

= $510.75

Answer:

-450

Step-by-step explanation:

Say the first number is x to get the idea.

The first 150 terms are 150x - 5 * 150

15x - 750

300 - 750 = -450

Answer:

a) y = 5x

b) y = 60

Step-by-step explanation:

y ∝ x

So, y = kx      -----(1)

Where k is the constant of proportionality

Now, y = 30, x = 6

Putting in (1)

30 = k(6)

Dividing both sides by 6, we get

k = 5

Now, Putting k=5 in (1)

So,

a) The equation connecting x and y is :

y = 5x

b) x = 12, Putting in (1)

y = (5)(12)

y = 60

Answer:

D. Between the ladder and the ground

Step-by-step explanation:

The 75° is made by the ladder leaning on the tree. So the angle would be from the ground up to the ladder.

Answer:

12)x=26.125°

∠P  = 115.625°

∠Q =21.125°

∠R=43.25°

13)x=52°

∠L=52°

∠J =45°

∠K =69°

14)x=11°

∠C = 36°

∠D =36°

∠B = 108°

15)x=7

WX = 52

WY=52

XY =29

Step-by-step explanation:

12)In ∆PQR

∠P is 14 less than five times x = 5x-15

∠Q is five less than x=x-5

∠R is nine less than twice x=2x-9

Angle sum property of triangle : The sum of all angles of triangle is 180°

So,5x-15+x-5+2x-9=180

8x-29=180

8x=180+29

[tex]x=\frac{180+29}{8}[/tex]

x=26.125

So,∠P  = 5x-15 =5(26.125)-15=115.625°

∠Q =x-5=26.125-5=21.125°

∠R=2x-9=2(26.125)-9=43.25°

13)  In ∆JKL

Let the angle L be x

∠L=x

∠J is seven less than ∠L=x-7

∠K is 21 less than twice ∠L=2x-21

Angle sum property of triangle : The sum of all angles of triangle is 180°

So, x+x-7+2x-21=180°

4x-28=180°

4x=180+28

[tex]x=\frac{180+28}{4}[/tex]

x=52

∠L=x=52°

∠J =x-7=52-7=45°

∠K =2x-21=2(45)-21=69°

14)In ∆BCD

BC ≅ BD(Given)

Opposite angles of equal sides are equal

So, ∠C =∠D

∠C = 5x – 19

∠D = 2x + 14

So, 5x-19=2x+14

3x=33

x=11

∠C = 5x – 19=5(11)-19=36°

∠D = 2x + 14=2(11)+14=36°

∠B = 13x – 35=13(11)-35=108°

15) In ∆WXY

∠X ≅ ∠Y(Given)

Opposite sides of equal angles are equal

WY=WX

WX = 9x – 11

WY = 7x – 3

So, 9x-11=7x-3

2x=14

x=7

So, WX = 9x – 11=9(7)-11=52

WY=52

XY = 4x + 1=4(7)+1=29

Answer:

A slope of zero means a horizontal line (parallel to the x axis). So the line is y=-6, which is the y intercept. There is no x term because y=-6 for all x.

Step-by-step explanation:

Answer: y + 10 = -9(x - 6)

Step-by-step explanation:

Use this formula to solve for point-slope form: y - y1 = m(x - x1)

m would be the slope and the given slope is -9

y1 refers to the given y coordinate and x1 refers to the given x coordinate.

y + 10 = -9(x - 6)

[tex]24x+40[/tex]

Answer:

As Sophie has just taken the medicine, the quantity of drug present in her body is 500mg

Amount left from 1st dose = 4.5/100 × 500 = 22.5mg

Amount of Drug after 2nd dose = Amount left from 1st dose + 2nd dose taken.

Amount of Drug after 2nd dose = 22.5mg + 500mg

Amount of Drug after 2nd dose = 522.5mg

Amount left from 2nd dose = 4.5/100 × 522.5 = 23.513 mg

Amount of Drug after 3rd dose = Amount left from 2nd dose + 3rd dose taken.

Amount of Drug after 3rd dose = 23.513mg + 500mg

Amount of Drug after 3rd dose = 523.513 mg

Amount left from 3rd dose = 4.5/100 × 523.513 = 23.558mg

Amount of Drug after 4rth dose = Amount left from 3rd dose + 4rth dose taken.

Amount of Drug after 4rth dose = 23.558mg + 500mg

Amount of Drug after 4rth dose = 523.558 mg

The pattern formed above can be written in the form of sum of finite geometric series:

Sₙ = 500 + 500(0.045) +500(0.045)² + ........................500(0.045)ⁿ

Sₙ = 500(1 + 0.045 + 0.045² ........................0.045ⁿ)

Where

Sₙ = Sum till nth term

a = 500

r = 0.045

As Sophia takes medicines 2 times a day, she takes medicine 20 times in 10 days. So substitute n=20 in the formula for the sum of finite geometric series

[tex]S_n=a\frac{(1-r^n)}{1-r}\\S_{20}=500(\frac{1-0.045^{20}}{1-0.045})\\S_{20}=523.5602~\text{mg}[/tex]

Greatest amount of antibiotic present = 523.5602 mg

This amount is almost constant after 3rd dose, so it will occur after every dose after 3rd dose

After 1st dose = 500mg

After 2nd dose = 522,5mg

After 3rd dose = 523.513 mg

After the the amount left in the body almost remains constant.

Which means that after each dose, the amount in body is maximum, at the end of the 12 hours, the amount reduces to 4.5%, which reaches almost the same maximum after taking another dose.

Answer:

x = -5 or x = -4/3

Step-by-step explanation:

First possibility.

|2x − 1| = |4x + 9|

2x - 1 = 4x + 9

2x - 4x = 9 + 1

-2x = 10

x = 10/-2

x = -5

Second possibility.

2x - 1 = - (4x+9)

2x - 1 = -4x - 9

2x + 4x = -9 + 1

6x = -8

x = -8/6

x = -4/3

Answer:

[tex] |2x - 1| = |4x + 9| [/tex]

this equation can be separated into 2 possible cases :

[tex]2x - 1 = 4x + 9[/tex]

and

[tex]2x - 1 = - (4x + 9)[/tex]

solve the 1st possible case:

[tex]2x - 1 = 4x + 9[/tex]

[tex]2x - 4x = 9 + 1[/tex]

[tex] - 2x = 10[/tex]

[tex]x = - \frac{10}{2} [/tex]

[tex]x = - 5[/tex]

solve the 2nd possible case:

[tex]2x - 1 = - (4x + 9)[/tex]

[tex]2x - 1 = - 4x - 9[/tex]

[tex]2x + 4x = - 9 + 1[/tex]

[tex]6x = - 8[/tex]

[tex]x = \frac{ - 8}{6} [/tex]

[tex]x = - \frac{4}{3} [/tex]

so the x value for this equation is:

x = -5 or x = -1.333

Answer:

1/26

Step-by-step explanation:

In a standard pack of cards, there are 52 total cards and 4 aces, two black aces and two red aces.

The probability of selecting an ace is therefore:

4/52 = 1/13

The probability of flipping a coin and it landing on tails is:

1/2

Therefore, the probability of selecting an Ace and the coin landing on tails is:

1/13 * 1/2 = 1/26

Answer:

(2, 9)

Step-by-step explanation:

y=2x+5

x=2 ⇒ y=2*2+5=4+5=9

so the point is (2, 9)

Answer:

y = 9

Step-by-step explanation:

y = 2x+5

It is given (2,__), (x,y).

We must find the y coordinate.

Put x as 2.

y = 2(2) + 5

Multiply both the terms.

y = 4 + 5

Add the terms.

y = 9

Answer:

nth term = 2n^2 - 3n - 6.

Step-by-step explanation:

                      n   =  1   2    3    4     5     6    7  

                             - 7   -4   3   14   29   48   71  

Differences                3    7   11    15   19    23

Differences                   4   4     4    4     4

So the first term in the Rule is 2n^2

Subtracting  the values of 2n^2 from the original terms:

                  - 7   -4   3      14   29   48   71  

2n^2           2     8  18    32   50   72   98

Subtrct       -9   -12 -15  -18   -21   -24   -27

                       -3     -3    -3   -3    -3     -3

So we have -3n  and the last  term is  -6 because    -7 = 2(1)^2 -3 - 6  and the other terms fit this pattern as well.

The nth term rule of the provided quadratic sequence to find the n'th term of the sequence is 2n²-3n-6.

The quadratic sequence is the series of the numbers in which the rule for the n'th term included an n squared term (n²). The quadratic equation for n can be given as,

[tex]an^2+bn+c[/tex]

Here, (2a) is equal to the second difference, (3a+b) is equal to the first difference and (a+b+c) is equal to the first term.

The sequence given in the problem is

[tex]-7, -4, 3, 14, 29, 48, 71[/tex]

Thus, (a+b+c) is,

[tex]a+b+c=-7[/tex]                ......1

The first difference between the sequence is,

[tex]3,7,11,15,19,23[/tex]

Thus, the value of (3a+b) is,

[tex]3a+b=3\\b=3-3a[/tex]                      ......2

The second difference between the sequence is,

[tex]4,4,4,4,4[/tex]

Thus, the value of 2a is,

[tex]2a=4\\a=\dfrac{4}{2}=2[/tex]

Put this value in equation 2 as,

[tex]b=3-3\times2\\b=-3[/tex]

Put the value of a and b in equation 1 as,

[tex]2-3+c=-7\\c=-7+1\\c=-6[/tex]

Put these values in the above formula as,

[tex]2n^2-3n-6[/tex]

The nth term rule of the provided quadratic sequence to find the n'th term of the sequence is,

[tex]2n^2-3n-6[/tex]

Step-by-step explanation:

The question is incomplete. Here is the complete question.

"Mr. Anderson cuts a piece of metal in the shape of the triangle shown. The piece of metal has an area of 7 1/2 square feet. What is the base of the piece of metal? triangle 5ft high"

Area of the triangle = 1/2 * base * height

Given the area of the piece metal = 7 1/2 ft² and its height = 5ft (since the triangle is 5ft high). On substituting the values in the formula;

7 1/2 = 1/2* base * 5

15/2 = 5/2 * base

15 = 5 * base

base = 15/5

base = 3ft

The base of the piece of metal is 3ft

Answer:

y = -(3/4)x + 19

Step-by-step explanation:

If you look at the line, you have the y intercept already. so there is less work to do.

The equation for a linear line is y=mx+b (or c depending on which country you are from) where m is the gradient and b is the y intercept

b = 19 from the diagram

To find the gradient, it is y2-y1/x2-x1, so pick any 2 points, let say  (16,7) and (0,19)

m = 19-7/0-16

= 12/-16

=3/-4
