geometry right triangle

The necklaces will be sold for $8.75.

All you have to do is devide 201.25 by 23 and you will get your answer.

Answer:

2.57 and 11/3 and 3.14

Step-by-step explanation:

Answer:

Let n be the number of 25 cent stamps.Then, 28 - n must be the number of 29 cent stamps.Tim paid $7.60 the stamps.

0.25n + 0.29(28 - n) = 7.60

This means that n stamps at 25 cents a piece plus (28 - n) stamps at 29 cents a piece sum to $7.60.Solve for m.

0.25n + 8.12 - 0.29n = 7.60

-0.04n = -0.52

n = 13

So, Tim bought 13 25-cent stamps and 28 - 13 = 15 29-cent stamps

Answer: 16,21

Step-by-step explanation:

There are two ways you can solve this problem using substitution and elimination.

In this answer, I'm going to be using substitution.

First, you make two equations based on the information given.

The two equations are 0.15x+0.2y=6.6 and X+Y=37.

In the second problem subtract y to move it to the other side to get X=37-y.  

Now that you got x= make a new equation which should be 0.15(37-y)+0.2y=6.6 use distributive property to get 5.55-.15y+0.2y=6.6.

Then, subtract 5.55 by 6.6 to get 1.05 and 0.2y+-.15y to get 0.05 y.

Now you have 0.05y=1.05 divided 0.05 and 1.05 to get 21.

Now plug 21 into the X+Y=37 equation to get X+21=37 subtract 21 from 37 to get X=16.

So X=16 and Y=21, so the answer is 16,21.

Answer:

The slope is y=0.59x so 0.59

The y intercept is 0

Answer: 13440 grams

Step-by-step explanation:

Since 1 kg is 1000 g, multiply 0.64 by 1000 to find how many grams are in a kilogram.

0.64x1000

=640 grams

She uses 640 grams each day.

How many grams does he use in 3 weeks?

1 week has 7 days

3 weeks has 21 days

3x7=21

640x21

13440 grams

Answer:

Step-by-step explanation:

I think you mean 3(x+8)², not 3(x+8)2. If you cannot type ², use ^ to mark the exponent: 3(x+8)^2.

3(x+8)² + 8 = 83

3(x+8)² = 75

(x+8)² = 25

x+8 = ±√25

x+8 = ±5

x = -8 ± 5 = -3, -13

Answer:

The measure of the arc length is 62 degrees

Step-by-step explanation:

Here, we want to find the given arc measure

Mathematically, we are going to use the angle arc relationship

For the angle arc relationship, the measure of the central angle is simply the measure of the arc

In this case, the central angle is 62: this means that the given arc measure is 62 degrees too

56.5 in^2

Step-by-step explanation:

The volume of a cone is π[tex]r^{2}[/tex]h/3. The radius is d/2=6/2=3

V=(3.14 x [tex]3^{2}[/tex] x 6)/3

 =(3.14 x 54)/3

 =169.56/3

 =56.52

Answer:

$317

Step-by-step explanation:

Formula for compound interest is;

A = P(1 + (r/n))^(nt)

For melanie;

P = $3800

r = 2⅜% = 0.02375

n = 12/4 = 3

t = 16 years

Thus;

A = 3800(1 + (0.02375/3))^(3 × 16))

A ≈ $5548

For Sébastien;

P = $3800

r = 2¾% = 0.0275

n = 12

t = 16

Thus;

A = 3800(1 + (0.0275/12))^(12 × 16))

A ≈ 5865

Difference between Sébastien and Melanie's final amount = $5865 - $5548 = $317

Answer:

The required division is 658 and 342.

Step-by-step explanation:

Let the parts be x and y.

47x + 19y = 1000

let try 2digit number for x and y by inspection 14 and 19 best fit.

47*14 + 18*19 = 1000

658 + 342 = 1000

Answer:

Lilly, since the angles are the same we can set the equal to each other, that's the "trick" of this problem

Step-by-step explanation:

3x + 50 = 6x - 10

Answer:

s = 47

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles

s+45 = s+6  + s-8

Combine like terms

s+45 = 2s-2

Subtract s from each side

s+45-s =2s-2-s

45 =s-2

Add 2 to each side

45+2 = s-2+2

47 =s

Step-by-step explanation:

a) y=[tex]x^{2} -4x[/tex]

x=-1 ⇒ y=[tex](-1)^{2} +4=1+4=5[/tex]

x=1    ⇒  y=[tex]1^{2} -4=1-4=-3[/tex]

x=2 ⇒   y=[tex]2^{2} +8=4-8=-4[/tex]

x=4   ⇒  y=[tex]4^{2} -16=16-16=0[/tex]
