How many metres of cloth 4.4 m wide will be required to make a conical tent of radius of whose base is 3.5m and whose height is 8.4m .

Answers

➢ Answєr :

[tex]\Huge{\boxed{\sf{\red{22.98m}}}}[/tex]

➢ Explαnαtion :

Givєn :

Radius of the tent,r = 3.5 mHeight of the tent, h = 8.4 m

To Find :

length of the cloth required.

Solution :

According to the question,

Slant height, l = [tex]\displaystyle{\sf{ \sqrt{{r}^2 + {h}^2} = \sqrt{{3.5}^2 + {8.5}^2}}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ = 9.192m}}[/tex]

curved surface area = [tex]\displaystyle{\sf{ \pi rl}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ \frac{22}{7} \times 3.5 \times 9.192{m}^2}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ 101.112}}[/tex]

i.e., Area of the cloth is 101.11m²

Now, length of the cloth required = [tex]\displaystyle{\sf{ \frac{area}{width}}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ \frac{101.11}{4.4}}}[/tex]

[tex]\implies[/tex] [tex]\large{\boxed{\sf{\red{22.98m}}}}[/tex]

Solve the equation 4+x/-9=6

Answers

Answer:

x = -18

Step-by-step explanation:

4+ x / -9 = 6

x / -9 = 6 - 4

x / -9 = 2

x = 2*-9

x = -18

found this deimos Google hope this helps -

x in (-oo:+oo)

x/4-9 = 6 // - 6

x/4-9-6 = 0

1/4*x-15 = 0 // + 15

1/4*x = 15 // : 1/4

x = 15/1/4

x = 60

Can someone please answer the two questions circled :>

Answers

Answer:

For question 2 the slope is 1. So what you do is get the points you need to put on the graph and move them up one. Like how you did on question 1.

(0.5, 5) (1, 10) (1.5, 15) (2, 20) (2.5, 25)

Question 3 is the same thing but the slope is now 2. Then you would have to pin the points as...

(1, 2) (2, 4) (3, 6) (4, 8) (5, 10)

Hope this helped :)

Division first:

-2/5 / 8/15

When dividing two fractions flip

The second one over and multiply:

-2/5 x 15/8 = (-2x15)/(5x8) = -30/40 = -3/4

Now you have:

2-3/4-3/4

2-3/4 = 1 1/4

1 1/4 - 3/4 = 1/2

Consider the function g(x) = -3x - 4 if the domain value is selected from the set {-8, -2, 0, 3}, which of the following is a corresponding range value?

A. 18
B. -10
C. -13
D. -5

Answers

Answer:

C. -13

Step-by-step explanation:

Solve for g(x) by replacing x with each domain value in the set. Solving for g(x) will give you these numbers:

{20, 2, -4, -13}

-13 is the only value that appears in the range set and in the multiple choice solutions. Therefore, the answer is C. -13

C. [tex]-13[/tex] is a corresponding range value.

The domain of a function refers to the set of all values for which the function is defined.

The range is the set of all values that function takes for the given values of domain.

Domain is [tex]\boldsymbol{\left \{ -8,-2,0,3 \right \}}[/tex]

[tex]g(x)=-3x-4[/tex]

[tex]g(-8)=-3(-8)-4[/tex]

         [tex]=20[/tex]

[tex]g(-2)=-3(-2)-4[/tex]

         [tex]=2[/tex]

[tex]g(0)=-3(0)-4[/tex]

       [tex]=-4[/tex]

[tex]g(3)=-3(3)-4[/tex]

       [tex]=-13[/tex]

Range is [tex]\boldsymbol{\left \{ 20,2,-4,-13 \right \}}[/tex]

So, [tex]\boldsymbol{-13}[/tex] is a corresponding range value.
