Which ratio is not equivalent to 2 : 7?

A. 8:28
B. 14:49
C. 20:65
D. 22:77

Answer:

The height of the kite off the ground is 155.562 feet

Step-by-step explanation:

Given

[tex]Length = 220ft[/tex]

[tex]Angle = 45 \deg[/tex]

Required

Determine the height the kite is from the ground

This question is best explained with the following attachment

From the attachment, we have that the illustration of the question forms a right angled triangle triangle and required to solve for h

The relationship between h, 220 and 45 degrees is:

[tex]Sin\ \theta = \frac{Opposite}{Hypothenuse}[/tex]

Where

[tex]\theta = 45 \deg[/tex]

[tex]Opposite = h[/tex]

[tex]Hypothenuse = 220[/tex]

So, we have:

[tex]Sin\ 45 = \frac{h}{220}[/tex]

Multiply both sides by 220

[tex]h = 220 * sin\ 45[/tex]

[tex]h = 220 * 0.7071[/tex]

[tex]h = 155.562[/tex]

Hence, the height of the kite off the ground is 155.562 feet

Answer:

y=(14-8x) divided by 2

Step-by-step explanation:

minus 8x from both side you get

2y=14-8x

then you divide by 2

y=(14-8x) divided by 2

thats the furthest it can be simplified

Answer: x=  1/4 y = +  7/4

Step-by-step explanation:

Step 1: Add -2y to both sides.

8x + 2y + - 2y = 14 + −2y

8x = −2y + 14

Step 2: Divide both sides by 8.

8x /8 = -2y + 14/8

x=  1/4 y = +  7/4

54.25 x 0.08=4.34 TAX

54.25 x 0.17= 9.22 TIP

Add:

54.25+4.34+9.22= 67.81.

Divide:

67.81 ÷ 2 =33.905

So arround 33. 91 if you rounded it off.

Step-by-step explanation:

Answer:

The height of the building that casts a shadow of 78m meters is 39m

Step-by-step explanation:

Let height be represented by H and the shadow is S

as they are directly proportional

H [tex]\alpha[/tex] s

H=KS   ( where K is a proportionality constant)

H=2.5m , S= 5m

On substituting in the equation

2.5 = K*5

K= 0.5

Now the equation becomes

H = 0.5*S

Height when shadow is 78m

H= 0.5*78

H= 39m

Number of hours Jonas practising, j = 1 hr.

Number of hours Bradley practising, b = 3 hr.

Total minutes of hour Jonas practised :

[tex]T_j = 1\times 365\times 2\times 60\ minutes\\\\T_j = 43800\ minutes[/tex]

Total minutes of hour Bradley practised :

[tex]T_b=(1+2)\times 365\times 2\times 60\ minutes\\\\T_b =131400\ minutes[/tex]

Therefore, Jonas and Bradley practice for 43800 minutes and 131400 minutes respectively.

Hence, this is the required solution.

Answer:

Step-by-step explanation:

Terms are single numbers, variables, or the product of a number and variable.

A factor is one part of a product.

Hint #22 / 4

The expression \red{ab} + \green{cd}+ \blue{ef}ab+cd+efstart color #df0030, a, b, end color #df0030, plus, start color #28ae7b, c, d, end color #28ae7b, plus, start color #6495ed, e, f, end color #6495ed + \purple{gh}ghstart color #9d38bd, g, h, end color #9d38bd consists of four products of variables connected by addition so each product is a term. The first term is \red{ab}abstart color #df0030, a, b, end color #df0030, the second term is \green{cd}cdstart color #28ae7b, c, d, end color #28ae7b, the third term is \blue{ef}efstart color #6495ed, e, f, end color #6495ed, and the fourth term is \purple{gh}ghstart color #9d38bd, g, h, end color #9d38bd.

Hint #33 / 4

Each of the terms is the product of two variables. Each variable is a factor because it is one part of a product. The expression \red{ab}abstart color #df0030, a, b, end color #df0030 contains two factors: \red{a}astart color #df0030, a, end color #df0030 and \red{b}bstart color #df0030, b, end color #df0030. Similarly, the expressions \green{cd}cdstart color #28ae7b, c, d, end color #28ae7b, \blue{ef}efstart color #6495ed, e, f, end color #6495ed and \purple{gh}ghstart color #9d38bd, g, h, end color #9d38bd also contain two factors.

Hint #44 / 4

The expression ab+cd+ef+ghab+cd+ef+gha, b, plus, c, d, plus, e, f, plus, g, h consists of 444 terms, and each of these terms contains 222 factors.

Answer:

Step-by-step explanation:

Firstly, we can simplify the ratio of boys to girls to  

1

:

2

.

Then, to find out how many students each ratio represents, we add up  

1

and  

2

to get  

3

(

1

+

2

=

3

).

By dividing  

3

by the number of students, we can find how many students ONE ratio represents:  

24

3

=

8

.

So ONE ratio is equal to  

8

boys. Since our simplified ratio of boys to girls is  

1

:

2

already, we do not have to do further multiplying - the number of boys is simply  

8

.

For the girls, simply multiply  

2

by

to get

Answer:

rise over run

One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.

Answer:

angle edf is 70

Step-by-step explanation:

triangle angles always add up to 180. So if you have 40 degrees at angle e already, 180-40 = 140

since side DE and side EF are congruent, that means its an isosceles triangle. One rule for that type a triangle is that the two base angles are equal. So you can just do 140/2 = 70

hope that helps!

Answer:

120

Step-by-step explanation:

theyre vertical angles and theyre the same degrees so it would be 120 hope this helps!
