Answer:

A. C=0.15*8

Step-by-step explanation:

3 pencils for $0.45, think about how much one pencil costs? so divide 0.45 by 3 and get 0.15 which basically means 1 pencils is 15 cents, multiply that by the amount of pencils fernando wants which is 8 and that's your equation

so  5 <= A <= 40

Answer:

3/2 or 1.5 or 1 1/2

Step-by-step explanation

To divide, you must switch the -1/4 to its reciprocal which is -4/1 and then multiply the fractions (-3/8 * -4/1) and since negative - negative = positive. It's a positive.

Answer:

The discount is $2.25 and the final price will be $12.74

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 14.99 × 15/100

Discount = 14.99 x 0.15

You save = $2.25

Final Price = Original Price - Discount

Final Price = 14.99 - 2.2485

Final Price = $12.74

hope this helps and is right. p.s. i really need brainliest :)

Answer:

$12.74

Step-by-step explanation:

15% of 14.99 dollars

14.99-2.25=12.74

Final answer=12.74 dollars

Answer:

34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?

Answer:

Step-by-step explanation:

We can use the formula for the area of a triangle, to help us find the height:

Area=12⋅b⋅h

Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:

92=12⋅23⋅h

Isolate h by multiplying both sides by 2 and dividing both sides by 23.

hh=2⋅9223=8

The height is 8 inches.

Answer:

probability = 0.07777

Step-by-step explanation:

there are 10 chips

white  1

red     4

green 2

blue   3

the probability of choosing the W chip is 1/10  or  0.10      

now there are 9 chips left (the first chip was not replaced)

the probability of choosing a non-green chip is (9-2)/9 =  7/9  = 0.7777  

so now I THINK you multiply the two probabilities to get the total probability

probability = 0.1 ·0.7777

probability = 0.07777    which makes sense it has to be less than 0.1

Answer:

1/15

Step-by-step explanation:

2/10 x 3/9= 6/90

6 divided by 6

90 divided by 6

=1/15

Answer:

sin x = 0.4706

Step-by-step explanation:

Given that,

Height, h = 8

Base, b = 15

Let H be the hypotenuse of the triangle. Using Pythagoras theorem,

[tex]H=\sqrt{8^2+15^2} \\\\H=17[/tex]

We know that,

[tex]\sin\theta=\dfrac{h}{H}[/tex]

So,

[tex]\sinx=\dfrac{8}{17}\\\\\sin x=0.4706[/tex]

So, the correct option is (b).

Step-by-step explanation:

there are actually no restrictions. even with a negative x, squaring it makes for a positive result.

Step-by-step explanation:

The mean is the usual average, so add all of the numbers and then divide.

The mode is the number that is repeated more often than any other.

The range is the largest value and smallest value subtracted.

Answer:

Answer bellow

Step-by-step explanation:

To find mean(average) get all the numbers and and add them together after devide the added number by the number of numbers

To find mode rewrite all the numbers and look for numbers that are repeating (it can be more than one)

To find range take the biggest number from the data set and subtract it from the smallest number in the data set

Answer:A truncated cone and a sphere

Step-by-step explanation:

I just did it.

The combination of geometric shapes can she use to best estimate the vase's volume is a truncated cone and a sphere.

Sophie needs to determine the amount of water that will fit into her new vase, as shown below.

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

We have to determine the combination of geometric shapes can she use to best estimate the vase's volume.

Therefore the combination of geometric shapes can she use to best estimate the vase's volume is a truncated cone and a sphere.

Answer:

D [tex] (x +6) ^2 +(y-1)^2 =7 [/tex]

Step-by-step explanation:

Center of the circle (h, k) = (-6, 1)

Area of the circle [tex] =\pi r^2 [/tex]

[tex] 7\pi=\pi r^2 [/tex]

[tex] \frac {7\pi}{\pi} =r^2 [/tex]

[tex]r^2=7[/tex]

[tex]r=\sqrt 7[/tex]

Radius [tex] r=\sqrt {7}[/tex]

Equation of circle in center radius form is given as:

[tex] (x - h) ^2 +(y-k) ^2 =r^2 [/tex]

Plugging the values of h, k and r in the above equation, we find:

[tex] [x - (- 6)] ^2 +[y-1 ]^2 =(\sqrt {7})^2 [/tex]

[tex] (x +6) ^2 +(y-1)^2 =7 [/tex]

Answer: The ratio of Mike and Sam Heights are  S:M=5:4

Step-by-step explanation:

Ravi is 3/4 as tall as Sam.

Consider the equation is  3/4 *R=S

Mike is 5/3 as tall as Ravi.

Then, the equation is 5/3 *M=R

Solve the two equation to find ratio of mikes and sam height.

3/4*R=S   Eq(1)

Rearranging eq (1) for R

R=4/3 *S      Eq(3)   made from eQ (1)

R=5/3*M   Eq(2)

Comparing   Eq 2 &3  equations

4/3*S=5/3*M

S/M=(5/3)*(3/4)

S/M=5/4

Answer:

630 ft

Step-by-step explanation:

(11 * 15) * 2 = 330 ft

(5 * 15) * 4 = 300 ft

330 + 300 = 630 ft

Given:

The scale model of an object has a scale of 1cm : 2ft.

The actual object is 11 feet tall.

To find:

The height of the model.

Solution:

It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.

Let the height of the model be x cm.

[tex]\dfrac{x\ cm}{11\ ft}=\dfrac{1\ cm}{2 \ ft}[/tex]

[tex]x\ cm=\dfrac{1 \ cm\times 11\ ft}{2 \ ft}[/tex]

[tex]x\ cm=5.5\ cm[/tex]

Therefore, the model is 5.5 cm tall.
