Answers

From the figure, the value of tan j is 13/9

How to determine the value of tan j?

The tangent of an angle is calculated using:

tan(j) = opposite/adjacent


From the figure, we have:

opposite = 13

adjacent = 9

So, we have:

tan(j) = 13/9

Hence, the value of tan j is 13/9

The circumference of a pipe is 9.24 centimeters. What is the diameter of the pipe? Use 3.14 for ℼ and do not round your answer.

Answers

Hi Student!

The first step that we need to take when approaching this problem is to extract the important information that was given in the problem statement.  Reading through it, we can see that we are given a circumference of a pipe being 9.24 centimeters.  After that, they are asking for us to determine what the diameter of the pipe is and tell us to use 3.14 instead of π.

Now that we have completed the information gathering, we can move onto the part of plugging in our values and solving for the unknown.

Plug in the values

[tex]C=d*\pi[/tex][tex]9.24\ cm=d*3.14[/tex]

Divide both sides by 3.14

[tex]\frac{9.24\ cm}{3.14}=\frac{d*3.14}{3.14}[/tex][tex]\frac{9.24\ cm}{3.14}=d[/tex][tex]2.942675\ cm=d[/tex]

Therefore, after solving for our unknown being the diameter we were able to determine that it is around 2.942675 centimeters using the Circumference formula.

Step-by-step explanation:

5) supplementary of two angles whose sum is 180°

3x + x = 180 → 4x = 180

4x / 4 = 180 / 4

x = 45

3x = 3(45)

6) complimentary of two angles whose sum is 90°

(8x + 5) + (3x + 8) = 90 → 11x + 13 = 90

11x = 77

11x / 11 = 77 / 11

The ratio of a green apple to red apple is 2:3. There are 78 red apples, what is the total number of apples in the store?

Answers

Answer:

The total is 130 apples.

Step-by-step explanation:

If the ratio of green to red apples is 2:3 and there is a total of 78 red apples, we can divide 78/3 which is 26. Since this is 1/3 of 78 we can multiply that by 2 to get 52 which is 2/3 of 78 which is the total amount of green apples. We dont stop here however. The question askes for the total amount of apples so we att 52 and 78 to get 130 which is the total amount of apples.

78/3 = 26

26*2 = 52

52+78 = 130

2
Based on the above information, answer the following questions: (a) How many square cm paper would be used to make 4 such caps ?
The bakery shop sells cakes by weight (0-5 kg, 1 kg, 1.5 kg, etc.). To have the required dimensions, how much cake should they order, if 650 cm3 equals 100 g of cake?
-30/3/1

Answers

a. The number of square cm of paper that would be used to make 4 caps is 3154.56 cm².

b. For the cake to have the required dimensions, they should order 1 kg of cake.

a.

The number of square cm of paper that would be used to make 4 caps is 3154.56 cm².

To find the number of square cm paper would be used to make 4 caps, we need to find the area of a cone.

Area of a cone

The area of a cone, A = πr² + πr[√(h² + r²)] where

r = radius of cone and h = height of cone

Now given that the base circumference of the cone is C = 44 cm. So,

C = 2πr where r = radius of base

So, r = C/2π = 44 cm/2π = 22 cm/3.142 = 7 cm

The height of the cone, h = 24 cm

So, A = πr² + πr[√(h² + r²)]

A = π(7 cm)² + π(7 cm)[√((24 cm)² + (7 cm)²)]

A = π(7 cm)² + π(7 cm)(7)[√((4 cm)² + (1 cm)²)]

A = 49π cm² + 49π cm[√(16 cm² + 1 cm²)]

A = 49π cm² + 49π cm[√(17 cm²)]

A = 49π [1 cm² + 4.123 cm²)]

A = 49π [5.123 cm²)]

A = 251.032π

A = 788.64 cm²

Since the area of one cap is A = 788.64 cm²,

the area of 4 caps is A' = 4A

= 4 × 788.64 cm²

= 3154.56 cm²

So, the number of square cm of paper that would be used to make 4 caps is 3154.56 cm².

b.

For the cake to have the required dimensions, they should order 1 kg of cake.

To find the amount of cake to be ordered, we need to find the volume of a cake since it is the volume of a cylinder.

Volume of a cylinder

The volume of a cylinder is V = πd²h/4 where

d = diameter of cake = 24 cm and h = height of cake = 14 cm

Substituting the values of the variables into the equation, we have

V = πd²h/4

V = π(24 cm)²(14 cm)/4

V = π(576 cm)²(14 cm)/4

V = 8064π cm³/4

V = 2016π cm³

V = 6333.45 cm³

So the volume of the cake is 6333.45 cm³

Since 650 cm³ equals 100 g, 6333.45 cm³ = 6333.45 cm³ × 100 g/650 cm =  974.4 g = 0.974 kg ≅ 1 kg.

So, for the cake to have the required dimensions, they should order 1 kg of cake.

Area of the rectangle is 126 sqaure meters. Length of the rectangle is 4 more than 2 times its width. Find length and width of the rectangle​

Answers

Answer:

Length of the rectangle = 18 mWidth of the rectangle = 7 m

Step-by-step explanation:

Given:

Area of the Rectangle = 126 m²Length of the rectangle is 4 more than 2 times its width.

To Find:

Length and width

Solution:

Let's assume :

Width of the rectangle = xLength of the recangle = 2x + 4

We know that,

[tex]\: \: \dashrightarrow\sf \: \: \: Length \times Width = Area_{(Rectangle)} \\ \\ [/tex]

On Substituting the required values, we get:

[tex] \\ \: \: \dashrightarrow\sf \: \: \:(2x+ 4)(x) = 126 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \:2 {x}^{2} + 4x = 126 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \:2 {x}^{2} + 4x - 126 =0 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \:2( {x}^{2} + 2x - 63) = 0 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \: {x}^{2} + 2x - 63 = 0 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \: {x}^{2} - 7x + 9x - 63 = 0 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \:x(x - 7) + 9(x - 7) \\ \\ \\ \: \: \dashrightarrow\sf \: \: \:(x - 7)(x + 9) = 0 \\ \\ \\ \: \: \dashrightarrow\sf \: \: \: \purple {x = 7 \: or \: - 9} \\ \\ [/tex]

Length of the side of the rectangle can't be negative. So, x = 7

Hence,

Width of the rectangle = x = 7 mLength of the rectangle = 2x + 4 = 2(7) + 4 = 18 m

Answer:

       length = 18 m

       width  = 7 m

Step-by-step explanation:

Finding the length and width of rectangle

       Let the width of the rectangle = w m

                                            Length = ( 2w + 4) m

Area of rectangle = 126 square meters

length * width     = 126

 (2w + 4) * w        = 126

     2w² + 4w       = 126

     2w² + 4w - 126 = 0

Divide the entire equation by 2

        w² + 2w - 63  = 0

        Sum  = 2

    Product = -63

   Factors  =  9 , (-7)        { 9 +(-7) = 2  & 9*(-7) = -63}

w² +  9w - 7w - 63 = 0       {rewrite the middle term using the factors}

w( w + 9) - 7(w + 9) =0

        (w +9)(w - 7)  = 0

{Ignore w +9 = 0, as measurement will not come in negative}

w - 7 = 0

       w = 7

length = 2w + 4

           = 2*7 + 4

           = 14 + 4

            = 18

length = 18 m  width = 7 m
