what is 2 times 8/10???​

Answer:

P=100-0.18

Step-by-step explanation:

Remember, percent means per every 100. So if the car cost $100, Mr. Stanley saves $18 on the car. Also, 18%= 0.18. And just for extra, single digit percents would be expressed with an extra zero in front of it, such as 5%=0.05.

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = [tex]\frac{25+9}{2}[/tex] = [tex]\frac{34}{2}[/tex] = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = [tex]\frac{25+17}{2}[/tex] = [tex]\frac{42}{2}[/tex] = 21 and

mean = [tex]\frac{17+9}{2}[/tex] = [tex]\frac{26}{2}[/tex] = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9

Answer:

g(q) = 5/8q

Step-by-step explanation:

-7q + 12r = 3q - 4r

Add 4r to each side

-7q + 12r+4r  = 3q - 4r+4r

-7q +16r = 3q

Add 7q to each side

-7q+7q +16r = 3q+7q

16r = 10q

Divide each side by 16

16r/16 = 10q/16

r = 5q/8

g(q) = 5/8q

Answer:

B. 5 cm3

Step-by-step explanation:

The volume of the oblique pyramid with a square base is 3.33 cm³.

Suppose the base of the pyramid has length = l units, and width = w units.

Suppose that the height of the pyramid is of h units, then:

[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]

is the volume of that pyramid.

The base is a rectangle with length = L units, and width = W units, so its area is:

[tex]b = l \times w\: \rm unit^2[/tex]

We are given that;

the base is about 2 cm long and that the height is about 2.5 cm long.

Now,

Using these values, we can estimate the volume as:

V ≈ (1/3) × Base Area × Height

V ≈ (1/3) × (2 cm)² × 2.5 cm

V ≈ (1/3) × 4 cm² × 2.5 cm

V ≈ 10/3 cm³

V ≈ 3.33 cm³

Therefore, an approximate volume of the pyramid will be 3.33 cm³.

Answer:

8,000

Step-by-step explanation:

Answer:

a. 28.

b 20.78.

Step-by-step explanation:

a. f(x) = 0.001(x -  10)(x + 20)(x - 40)

When x = 50

Height = f(40) = 0.001(50-10)(50+20)(50-40)

= 0.001(40*70*10)

= 0.001 * 28,000

= 28 units.

b.

Expanding the function we get

f(x) = 0.001(x  - 10)(x^2 - 20x - 800)

f(x) = 0.001(x^3 - 30x^2 - 600x + 8000)

f(x) = 0.001x^3 - 0.03x^2 - 0.6x + 8

Finding the derivative

f'(x) = 0.003x^2 - 0.06x - 0.6

This is zero for maxm/minm values:

0.003x^2 - 0.06x - 0.6 = 0

x = 27.32, - 7.32.

The values of the heights corresponding to these values of x are:

0.001(27.32-10)(27.32+20)(27.32-40)

= -10.39. and

0.001(-7.32-10)(-7.32+20)(-7.32-40)

= 10.39.

So the distance between A and B =  10.39 - (-10.39)

= 20.78.

Complete question:

Marvin is painting three squares shaped like the one below if it takes him exactly 4 cans of paint to paint square 3, five cans of paint to paint square 2 to how many cans of paint should he need to paint square one

Picture of squares is attached.

Answer:

9 cans of paint.

To paint square 1, he needs 9 cans of paint.

Step-by-step explanation:

Given that to paint square 3, four cans of paint are needed.

Therefore, let's take area of the square 3 as 4.

i.e a² = 4

Solving further, we have :

[tex] a = \sqrt{4} [/tex]

a = 2

We can say, each side of square 3 = 2 units

To paint square 2, five cans of paint are needed. Let's take the area of 2 to be 5.

i.e b² = 5

Solving further, we have :

[tex] b = \sqrt{5} [/tex]

We can say, each side of square 2 = [tex] \sqrt{5} [/tex] units

Using Pythagoras theorem, we have that the area of the square of a hypotenuse in a 90° angle is equal to the sum of the areas of the other two squares.

Therefore,

[tex] h^2 = 2^2 + \sqrt{5}^2 [/tex]

h² = 4 + 5

[tex] h = \sqrt{9} [/tex]

h = 3 units.

We now know one side of the square 1 is 3 units.

Area of square 1 = 3²

Area = 9.

Therefore to paint square 1, he needs 9 cans of paint.

The point (–3, –4) does lie on the circle with a center at (0, 0).

We know that the point (0, 5) lies on the circle, and since the center is at (0, 0), the distance from the center to (0, 5) gives us the radius.

Using the distance formula:

radius = √((0 - 0)² + (5 - 0)²)

= √0+25

=√25

= 5 units

So, the radius of the circle is 5 units.

Next, let's determine the distance from the center (0, 0) to the point (–3, –4) using the distance formula:

distance = √ (0- (-3))²+ (0-4(-4))²

= √ 3² + 4²

= √9 +16

= √25

= 5 units

The distance from the center to (–3, –4) is also 5 units.

Since the distance from the center to (–3, –4) is equal to the radius of the circle, the point (–3, –4) lies on the circle.

Therefore, the point (–3, –4) does lie on the circle with a center at (0, 0).

Answer:

The radius of the base of the small cone is 3 feet

Step-by-step explanation:

The question requires the determination of the radius of the smaller cone

Therefore, height of the larger cone = 10 feet

Base diameter of the larger cone = 10 feet

Height of horizontal plane of small plane above base of larger cone = 4 feet

Hence the height of the small cone = 6 feet

Therefore, by similar triangles, and tangents we have;

[tex]\frac{Height \, of \, small \, cone}{Height \, of \, larger\, cone} =\frac{Diameter \, of \, base \, of \, small \, cone}{Diameter \, of \, base \, of \, larger \ cone} =\frac{6}{10} = \frac{x}{10}[/tex]

Where:

x = The diameter of the base of the small cone

Therefore;

[tex]{x} = \frac{6}{10} \times 10 = 6 \, feet[/tex]

The radius of the base of the small cone = half the diameter of the base of the small cone

∴ The radius of the base of the small cone = (6 feet)/2 = 3 feet.

Answer:

the radius would be 3

Step-by-step explanation:

so what it's saying si there;s a cone with diameter 10 and height 10, the 4 feet above the bottom of the cone is the base of the smaller cone. The height of the smaller cone becomes 6, making the diameter 6 as the ratio becomes 6:6, and radius is diameter/2 becoming 3
