Margo makes jewelry with beads. Each necklace uses 48 beads. Each bracelet uses 22 beads. Margo wants to make 18 necklaces and 12 bracelets.

Which answer is the most reasonable estimate of the total number of beads she needs?


a. 1,000 because 40 × 20 + 20 × 10 = 1,000

b. 1,180 because 48 × 20 + 22 × 10 = 1,180

c. 1,400 because 40 × 30 + 10 × 20 = 1,400

d. 1,900 because 50 × 30 + 20 × 20 = 1,900

Answer:

a. 1/11 < 1/9 < 1/8 < 1/7 < 1/5 < 1/4

b. 4/12 < 4/10 < 4/7 < 4/5

c. 3/11 < 3/9 < 3/8 < 3/7 < 3/5 < 3/4

Answer: The answer is A 17in2

Step-by-step explanation:

In the question it states that the triangles are congruent (both the same).

  first I found the area of the top orange triangle.

the formula to find the area of a triangle is [tex]\frac{1}{2} bh[/tex] (base times Height).

so I did  [tex]\frac{1}{2} 3.23* 5.12[/tex]  which gave me 8.27.

Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.

the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

Answer:

slope is 4 and y-intercept is 12

Step-by-step explanation:

To solve this problem, let's actually just write the equation of the line in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Slope is change in y divided by change in x. Given (-3, 0) and (-2, 4), the slope will be: (4 - 0) / (-2 - (-3)) = 4 / 1 = 4. So, the slope is m = 4.

Now, our equation so far is y = 4x + b. To find b, plug in, say, -3 for x and 0 for y:

0 = 4 * (-3) + b

0 = -12 + b

b = 12

Then the slope is 4 and the y-intercept is 12.

Answer:

[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} } = \frac{0 - 4}{-3+2} = \frac{-4}{-1} = 4[/tex]

4 is the slope

now we have to plug in the slope intercept formula where m is 4

you can find b by plugging one of the points

I choose (-3,0) since it is easier to work with

0 = 4(-3) + b

0 = -12 + b

12 = b

Our y intercept is 12

finally the slope intercept form is

y = 4x + 12

Slope formula - (y2 - y1)/ (x2-x1)

Slope intercept form = y = mx + b

Step-by-step explanation:

Answer:

h = 12 inches

Step-by-step explanation:

The volume is  given by

V = Bh  where B is the area of the base and h is the height

Substituting V = 1080 and B = 90

1080 = 90h

Divide each side by 90

1080/90 = 90h/90

12 = h

10x+4=2x+20

10x-2x=20-4

8x=16

x=2

Answer: x=2

2(5x+2)=2x+20. Distribute

10x+4=2x+20. Switch sides and signs

10x-2x=20-4. Combine like terms

8x=16. Get X by it self

Answer:

The correct inequality is: b< -6 or b > 6

Step-by-step explanation:

The absolute value operator always results in a positive number, in such a way that if b > 0, then |b| = b, while if  b < 0, then |b| = -b. With this in mind, let's look at the inequality given:

|b| > 6

This will be true for values of b that are greater than 6 and values of b that are less than -6, due to the absolute value operator. Therefore the compound inequality that represents this situation is:

b< -6 or b > 6

Answer:

I think it is D (and)

Step-by-step explanation:

"Or" means that the b value can be less than -6 or greater than 6

so it could satisfy either one

so if you plug in a value that satifies one of the inequalities (ex: -7)

|-7|>6  and it works!

Answer:

(-4, 5)

Step-by-step explanation:

(-4, 5) are the correct coordinates of point B after reflecting the figure over the y-axis.

Answer:

A

Step-by-step explanation:

In the figure attached, the complete question is shown.

We have to transform all the fractions to new fractions with the same denominator, as follows:

1/8 *4/4 = 4/32

-3/16 *2/2 = -6/32

-1/4 *8/8 = -8/32

1/32

5/32

-1/16 *2/2 = -2/32

Now we can order the list simply comparing numerators:

-8/32, -6/32, -2/32, 1/32, 4/32, 5/32

or

-1/4, -3/16, -1/16, 1/32, 1/8, 5/32

The order from least to greatest is -1/4 < -3/16 < -1/16 < 1/32 < 1/8 < 5/32 option first is correct.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

We have a measurement data as shown:

1/8, - 3/16, - 1/4, 1/32,  5/32, - 1/16

We can write the above numbers as follows:

0.125, -0.1875, -0.25, 0,03125, 0.15625, -0.0625

The order from least to greatest:

-1/4 < -3/16 < -1/16 < 1/32 < 1/8 < 5/32

Thus, the order from least to greatest is -1/4 < -3/16 < -1/16 < 1/32 < 1/8 < 5/32 option first is correct.

Answer:

1248 cubic feet

Answer:

2π hours

Step-by-step explanation:

Given the following function:

h(t)=8*cos(t) + 11.5

we want to find its period. This function has the following form:

y = A*cos(B(x + C)) + D

where:

A = 8

B = 1

C = 0

D = 11.5

which period is computed as: 2π/B. Then, for the case of the problem:

period = 2π/1 = 2π hours

Hope This helps :D

Step-by-step explanation:

If the total worth of the roll is 50 cents, we know that there are 50 pennies in the roll, and therefore the roll has a height of 50 * 1.52 = 76 mm. The radius of a penny is half its diameter, or 19.05 / 2 = 9.525.

We can find its volume with the formula (πr²) * h, where r and h are the radius and height respectively, and we can approximate 3.14 for π. Plugging these in, we have (3.14 * (9.525)²) * 76 ≈ 2160.8 mm³. Hope this helps!

Answer:

  21,661.7 mm³

Step-by-step explanation:

The formula for the volume of a cylinder is ...

  V = πr²h

Here, we're given the diameter as 19.05 mm, so the radius is ...

  r = 19.05 mm / 2 = 9.525 mm

The thickness of one penny is 1.52 mm, but there are 50 of them in the roll. So the total height of this cylinder is ...

  h = (1.52 mm)(50) = 76 mm

__

Using these numbers for radius and height in the volume formula, we find the volume of the roll of pennies to be ...

  V = π(9.525 mm)²(76 mm) = 21,661.7 mm³

The approximate volume of the roll of pennies is 21,661.7 mm³.
