A cheetah can run at a speed of 74.56 miles per hour. A racehourse can run at a speed of 38.9 miles per hour. How much faster can a cheetah run than a racehorse in miles per hour?

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

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:

[tex]k=1\text{ or } k=4[/tex]

Step-by-step explanation:

We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a binomial in the form (x - a), then our remainder will be P(a).

We are dividing:

[tex](x^2+5x+7)\div(x+k)[/tex]

So, a polynomial by a binomial factor.

Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k.

We want our remainder to be 3. So, P(a)=P(-k)=3.

Therefore:

[tex](-k)^2+5(-k)+7=3[/tex]

Simplify:

[tex]k^2-5k+7=3[/tex]

Solve for k. Subtract 3 from both sides:

[tex]k^2-5k+4=0[/tex]

Factor:

[tex](k-1)(k-4)=0[/tex]

Zero Product Property:

[tex]k-1=0\text{ or } k-4=0[/tex]

Solve:

[tex]k=1\text{ or } k=4[/tex]

So, either of the two expressions:

[tex](x^2+5x+7)\div(x+1)\text{ or } (x^2+5x+7)\div(x+4)[/tex]

Will yield 3 as the remainder.

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].

Answer:18

Step-by-step explanation:

Because 40% of 45 is 18

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

Explanation:

On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.

From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x

We get the following:

(5x+12)+(6x-8) = 180

5x+12+6x-8 = 180

(5x+6x)+(12-8) = 180

11x+4 = 180

11x = 180-4

11x = 176

x = 176/11

x = 16

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.
