Answer 1
Answer:  (b) 36 cm

====================================================

Work Shown:

r = radius = 7 cm

C = circumference of a full circle

C = 2*pi*r

C = 2*pi*7

C = 14*pi

C = 43.9822971502571 approximately

C = 43.9823

If we have a circle of radius 7, then the distance around the full circle is roughly 43.9823 cm.

Divide this over 2 to get the distance around half the circle

C/2 = 43.9823/2

C/2 = 21.99115

C/2 = 22 cm

This takes care of the curved portion. The straight portion is 2r = 2*7 = 14 cm which adds on to get 22+14 = 36 cm

Answer 2

Answer:

option b 36cm

Step-by-step explanation:

perimeter if the wire = diameter length + 0.5(2piradius) = 7+7+pi(7) = 35.991 cm = 36cm

Answer:

B

Step-by-step explanation:

Based on the amount that Sam saves and his living expenses, the amount he needs to save and the length of time it will take him to do so is B. 5,136; Approximately 24 months.

What are Sam's living expenses?

= Fixed essential expenses + Variable essential expenses

= 1,292 + 420

= $1,712

How much does Sam need to save?

Sam needs to save three times his expenses:

= 1,712 x 3

= $5,136

How long will it take Sam to save this amount?

= Amount to be saved / Amount saved monthly

= 5,136 / 210

= 24 months approximately.

________________________________________________________

The question is:

Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?

a. $1,712; approximately 8 months

b. $5,136; approximately 24 months

c. $6,486; approximately 30 months

d. $2,162; approximately 6 months

Does the following relationship represent a function?

Answers

yes Step-by-step explanation:

The given relation in the mapping diagram represents a function.

What is function in mathematics ?

A function in mathematics is an expression with a independent variable (x) in it. The variable is called independent because it is not dependent on any value to get its value. Function also has a dependent variable (y) whose value depend on x. Ex -

y = f(x) = ax + d

We have a relation as shown in the figure.

The given relation is a function as all the values of [x], has independent values of [y]. Two or more values of [x] can have same value of y.

Therefore, the given relation in the mapping diagram represents a function.

Noah went shopping for a new video game because of a sale. The price on the tag was
$32, but Noah paid $22.40 before tax. Find the percent discount.

Answers

The percent discount is 30%.
If you multiply $32 by .30, you will get $9.60. That is the amount of the discount. If you subtract $9.60 from $32, you will get $22.40 which is what he paid before tax. Therefore the percent discount is 30%.

Answer:

a. tan∠FKG = √3

b. tan∠BKG = 1

c.  [tex]tan\angle KDF = \dfrac{1}{\sqrt{3} }[/tex]

d. tan∠BCK = 1

e. The coordinates of the point g is (4, 4·√3)

Step-by-step explanation:

a. The trigonometric ratio for tan is given as follows;

[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]

Therefore, we have;

[tex]tan\angle FKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(60^{\circ}) = \dfrac{sin(60^{\circ})}{cos(60^{\circ}) } = \dfrac{\dfrac{\sqrt{3} }{2} }{\dfrac{1}{2} } = \sqrt{3}[/tex]

b.

[tex]tan\angle BKG = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(45^{\circ}) = \dfrac{sin(45^{\circ})}{cos(45^{\circ}) } = \dfrac{\dfrac{1 }{\sqrt{2} } }{\dfrac{1}{\sqrt{2} } } = 1[/tex]

c.

[tex]tan\angle KDF = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = tan(30^{\circ}) = \dfrac{sin(30^{\circ})}{cos(30^{\circ}) } = \dfrac{\dfrac{1 }{2 } }{\dfrac{\sqrt{3} }{2 } } = \dfrac{1}{\sqrt{3} }[/tex]

d. In right triangle, ΔBKC, ∠BCK = ∠BKC = 45°

∴ tan(∠BCK) = tan(45°) = 1

e. The x-coordinate of the point g is 4

The y-coordinate of the point g is 4 × tan(60°) = 4·√3

The coordinates of the point g is (4, 4·√3).
