line that is parallel y=-1.25x+7

Answer:

18-Yes 19-No 20-yes 21- yes

Step-by-step explanation:

18

1 to 4, 5 to 20

Yes, this is correct

WE can multiply 1*5 and 4*5 to get 5 to 20

19

Wrong

3 to 11, 1 to 3 isn't correct

For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)

So, no

20

2/3 is 2 to 3

14/21 is 14 to 21

If we multiply 2*7 and 3*7, we get 14 to 21

21 25 to 30 is  equal to 35 to 42

They just added 7 to both numbers

if we divide ratio 1 by 5, we get 5:6

if we divide ratio 2 by 7 we get 5 to 6

Answer:

250%

Step-by-step explanation:

Hi there!

In order to solve this problem, we have to divide 200 by 80.

When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.

Now we have the 0.5

A half is equivalent to 50%, so we add those two percentages together to get 250%.

I hope this helps!

Answer:

part 1:

see in the picture, E is the centre of the kite

1) AC = 2.EC = 40

2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29

3) ABE = 90⁰ - 51⁰ = 39⁰

4) BCE = BAE = 51⁰

part 2:

we have:

3x + 7 = (3x - 1 + 8x)/ 2

<=> 3x + 7 = 5.5x - 0.5

<=> 2.5x = 7.5

<=> x = 3

5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8

6) XY = 3.3 + 7 = 9 + 7 = 16

7) TW = 8.3 = 24

9) the width of the base is x (x > 0)

we have:

28.5 = (x + 25)/2

<=> x + 25 = 57

<=> x = 32

Step-by-step explanation:

Given that :

Total fraction of paint Carin has = 2/3 bottle

Fraction used to paint a model airplane = 1/6

Number of model. Airplanes 2/3 of a bottle could paint ;

Total fraction of paint / fraction used to paint a model airplane

(2/3) ÷ (1/6)

2/3 * 6/1

= 12 / 3

= 4 model airplanes

Answer: Weight of sand in each bag = 3.17 lb.

Step-by-step explanation:

Given : Total weight of sand = 63.4 lb

Total small bags = 20

Weight of sand in each small bag = (Total weight of sand ) ÷ (Total bags)

Weight of sand in each small bag = ( 63.4) ÷ (20)

Weight of sand in each small bag = 3.17 lb

Hence, the weight of sand in each small bag = 3.17 lb.

Answer:

3.17lb

The value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].

Given:

The function [tex]f[/tex] has an inverse and [tex]f(-3)=6[/tex].

To find:

The value of [tex]f^{-1}(6)[/tex].

Explanation:

If a point [tex](a,b)[/tex] lies on the function [tex]f(x)[/tex], then the point [tex](b,a)[/tex] must lies on the inverse function [tex]f^{-1}(x)[/tex].

According to the given value [tex]f(-3)=6[/tex], the point [tex](-3,6)[/tex] lies on the function [tex]f(x)[/tex]. So, the point [tex](6,-3)[/tex] must be lies on [tex]f^{-1}(x)[/tex].

[tex]f^{-1}(6)=-3[/tex]

Therefore, the value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].
