Answer 1

Answer:

Step-by-step explanation:

1. 3n+4n=28

         7n=28

           n=4

2. 2x+7-9=10

           2x=10+2

            2x=12

               x=6

3. 3(a+2)=-5

    3a+6=-5

         3a=-11

           a= -11/3

4. 2(3n-1)=19

      6n-2=19

          6n=21

            n=7/2

5. 3x-5-x+1=10

            2x=14

               x=7

6. -3-5=5-2a+7

      2a=20

        a=10

7. -5(n-2)= -15

        n-2=3

           n=5

8. Let the cost of each fan be y.

    6y+3y=1188

         9y=132

∴ The cost of each fan is $132.

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:

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%

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

Find C. Leave your answer in simplified radical form.

Answers

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.

A ganza is a percussion instrument used in samba music.

a. Find the surface area of each of the two labeled ganzas in terms of π , rounded to the nearest thousandths and as a decimal, round to the nearest whole number.

Surface area of smaller ganza =
π≈
cm2
Surface area of larger ganza =
π≈
cm2
b. The weight of the smaller ganza is 1.1 pounds. Assume that the surface area is proportional to the weight. What is the weight of the larger ganza to the nearest tenth of a pound?

The weight of the larger ganza is about
pounds.

Answers

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.

Surface area :

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]

C. 6 1/3
D. 6 5/6
E. 7 5/6​

Answers

Answer:

he would have bought 6 5/6 pounds of rice.

Step-by-step explanation:

4 1/2 + 2 1/3 = ?

First, you want to get common dominaters. And the closest number is 6

4 3/6 + 2 2/6 = 6 5/6

This can not be simplifyed so that would be your answer.

The total weight, in pounds, of rice purchased by Marcus in the two-day period is [tex]6\frac{5}{6}[/tex] pounds.

Addition of fraction:

It is given that,

Amount of rice purchased on Monday = [tex]4\frac{1}{2} pounds[/tex]

Amount of rice purchased on Tuesday[tex]=2\frac{1}{3} pounds[/tex]

the total weight, in pounds, of rice purchased by Marcus in the two-day period is computed as;

                            [tex]=4\frac{1}{2}+2\frac{1}{3} \\\\=\frac{9}{2} +\frac{7}{3} \\\\=\frac{27+14}{6} \\\\=\frac{41}{6}\\ \\=6\frac{5}{6} pounds[/tex]

Therefore, the total weight of rice is [tex]6\frac{5}{6}[/tex] pounds.

D (last one), [tex]x^2+y^2=45[/tex]

Step-by-step explanation:

We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

[tex]d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}[/tex]

[tex]d=3\sqrt{5}[/tex]

Since equation of circle is: [tex]x^2+y^2=r^2[/tex] we have to square the distance we just found, which gives us 45.

Answer:

x^2 + y^2 = 45

Step-by-step explanation:

(x − a ) ^2 + ( y − b ) ^2 =r^2

= (-3-0)^(2)+(6-0)^(2)

Tony Smith also was the president of the company. Tony Smith set up an account with Laker Express, a fuel provider, on behalf of Smith Services, Inc., and his drivers often would charge fuel purchases for the company trucks to that account. Laker Express then would bill Smith Services regularly for the charges on the account. After several months of low business, Smith Services ceased doing business and was dissolved in 2018, with its assets being distributed to creditors. Laker Express only recovered a small part of the amount owed by Smith Services, Inc. Tony Smith then opened up a new trucking service business as a sole proprietor. Laker Express sought to recover Smith Services' unpaid fuel charges, which amounted to about $35,000, from Smith. Smith argued that he was not personally liable for a corporate debt.
