Answer:

1036.2 sq. cm

Step-by-step explanation:

The surface area of the smaller ganza = 2πr2 + 2πrh

surface area = 2 x 3.14 x 3.5 x 3.5 + 2 x 3.14 x 3.5x 10

surface area = 76.93+ 219.8

surface area = 296.73 sq. cm

The surface area of the larger ganza  = 2πr2 + 2πrh

surface area = 2 x 3.14 x 5.5 x 5.5 + 2 x 3.14 x 5.5x 24.5

surface area = 189.97+846.23

surface area = 1036.2 sq. cm

a. The surface area of the smaller ganza is [tex]296.73cm^{2}[/tex]

    The surface area of the larger ganza is [tex]1036.2cm^{2}[/tex]

b. The weight of the larger ganza is [tex]3.84[/tex] pounds.

From given figure,

Radius of smaller ganza ,[tex]r_{1}=3.5/21.75cm[/tex]

height of smaller ganza, [tex]h_{1}=10cm[/tex]

a. The surface area of the smaller ganza is,

              [tex]S_{1}= 2 \pi r^{2} + 2\pi rh[/tex]

              [tex]S_{1}=2 * 3.14 * 3.5 * 3.5 + 2 * 3.14 * 3.5* 10\\\\S_{1}=76.93+ 219.8\\\\S_{1}=296.73cm^{2}[/tex]

The surface area of the larger ganza

               [tex]S_{2}= 2\pi r^{2} + 2\pi rh[/tex]

               [tex]S_{2}= 2 * 3.14 * 5.5 * 5.5 + 2 * 3.14 * 5.5* 24.5\\\\S_{2}= 189.97+846.23\\\\S_{2} = 1036.2 cm^{2}[/tex]

b. Since, the surface area is proportional to the weight.

and The weight of the smaller ganza is 1.1 pounds.

            [tex]\frac{1.1}{w}=\frac{296.73}{1036.2}\\ \\ w=\frac{1036.2*1.1}{296.73}\\ \\w=3.84[/tex]

Answer:

  7√2

Step-by-step explanation:

The triangle is a "special triangle", an isosceles right triangle. The side lengths of this triangle have the ratios 1 : 1 : √2. Multiplying these ratio values by 7, the length of the leg, you find ...

  c = 7×√2

  c = 7√2

_____

If you like, you can go through the Pythagorean theorem and/or trigonometry to find the same thing.

  7/c = sin(45°)

  c = 7/sin(45°) = 7/(1/√2) = 7√2

Or ...

  c² = 7² + 7² = 98 . . . . using the Pythagorean theorem*

  c = √98 = 7√2

__

* This requires you recognize the triangle is isosceles, so the other leg is also 7. Of course, you know that as soon as you see a 45° acute angle in a right triangle.

Answer:

consistent

Step-by-step explanation:

Answer:

no matter what value you substitute for x, the absolute value will force the result to be a positive number and any positive number is greater than -12

Answer: Since the absolute value of any number is always greater than or equal to zero, then the given inequality holds for every real number.

Explanation: It doesn't matter which number you substitute for x, as the absolute value will convert the number into a positive one, which will always be greater or equal to 0. Hence, every real number can be a possible answer.

Answer:

x=-3,x1/2

Step-by-step explanation:

f(x)=(2x-1)(x+3)

TI find x intercept/zero substitute

f(x)=0

0=(2x-1)x(x+3)

swap the sides of the equation

(2x-1)x(x+3)=0

when the product of factors equals 0,at least one factor is zero

2x-1=0

x+3=0

solve the equation for x

x=1/2

x+3=0

solve the equation of x

x=-3

The equation has two solution

x=-3

x=1/2

Step-by-step explanation:

the equation is in y=mx+b form (slope-intercept form)

y: y-axis

m: slope

x: variable

b: y-intercept

Answer:

Zero solutions; there are no variables and thus there are no solutions

Step-by-step explanation:

We start out with the equation 9 (x - 3) + 15 = 9x - 11

Which simplifies to 9x - 27 + 15 = 9x - 11

The 9x terms cancel each other out, and we're left with 15 - 27 = -11

And we end up with -12 = -11, which is not true.

This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.

Answer:

No solution

Step-by-step explanation:

9(x-3)+15= 9x-11

9x-27+15=9x-11

-15 on both sides

9x-27=9x-26

add 26 on both sides

9x -1=9x

add 1 on both sides

9x=9x+1

divide 9 on both sides

x=x+1/9

No solution

I say the answer would be No because the triangles are not the same Width, length or height..

label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area. Hope this helps! plz mark brainliest if possible

Answer:

Option 2 (open circle at 6 with arrow going to the right.

Step-by-step explanation:

Open circle means "excluding that number". Since x>6, x cannot be 6 so we have an open circle at 6. x>6 also means x has to be greater than 6, so we have the arrow going to the right since 7 is greater than 6, 8 is greater than 6, and so on so forth.

Answer:

Jamie's tickets = $187.48

Step-by-step explanation:

The amount for which Amanda bought tickets = $218

Jamie bought tickets to the same concert but paid 14% less than Amanda.

Jamie's tickets = [tex]218-14\%\ of\ 218[/tex]

We can solve it as follows :

[tex]218-14\%\ of\ 218=218-\dfrac{14}{100}\times 218\\\\=218-30.52\\\\=\$187.48[/tex]

So, the price of Jamie's tickets is $187.48.

Answer:

276 meters in the first 2 hours

Step-by-step explanation:

Given that,

Professional climbers climb 828 meters in 6 hours.

Let us assume we need to find how far did they climb in the first 2 hours.

6 hours = 828 m

⇒ 1 hour = 138 m

So, in 2 hours,

2 hours = 138 × 2 m

= 276 m

So, the climber climb 276 meters in the first 2 hours

Answer:

Step-by-step explanation:

amount of discount = $10

percentage discount = $10/$39.99 ≅ 0.25 = 25%

amount of sales tax = $1.95

sales tax rate = $1.95/$29.99 ≅ 0.065 = 6.5%

cost of jeans × 1.60 = $39.99

cost of jeans = $39.99/1.60 ≅ $24.99

discounted selling price = $29.99

markup = $29.99/$24.99 ≅ 1.20 = 20%
