PLEASE HELP WILL GIVE BRAINLIEST AND 15+ PONINTS AND PLEASE DONT PUT A RANDOM ANSWER OR TRY TO STEAL MY POINTS PLEASE AND THANKS U

Answer:

25%

Step-by-step explanation:

Let v, t be the current average speed and the time taken to reach the school respectively.

As distance = speed x time, so,

distance, d=vt...(i)

Let V be the new average speed in order to to take 20% less time than t.

So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t

As distance is constant, so

d= V(0.8t)= 0.8Vt

hBy using equation (i), we have

0.8Vt = vt

0.8 V = v

V= v/0.8=1.25v

Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]

[tex]=\frac{1.25v-v}{v}\times 100[/tex]

=25%

Hence, the percentage increase in the average speed is 25%.

Answer:

C. 0

because 2.8/9 <1

and 2.7>1

so 2.8/9 -2.7 <_ 0

Answer:

y = - 5x + 8

Step-by-step explanation:

Given that :

Intercept = 8

Slope = - 5

Recall, the general. Slope - intercept equation :

y = bx + c

Where;

b = slope ; c = intercept

Plugging the Given slope and intercept values, equation becomes ;

y = - 5x + 8

Answer:

No

Step-by-step explanation:

plug in the variables into the equation

(x,y)

(-1,2)

2(-1)+2=2

2*-1=-2

-2+2=0

2 does not equal 0 so therefore no, it is not a solution

Answer:

x > -2

Step-by-step explanation:

-6 (-2) + 30 > 36

12 + 30 > 36

42 > 36

Yes

The answer is [tex](x^3-8)(x^3+2)[/tex]

Step-by-step explanation:

Find two factors that equal -6 when added, and -16 when multiplied. Those are your outer numbers. The exponent of the first term is a 6, so you know when you multiply two numbers with exponents, you add them. 6/2=3.

I'm really sorry for the bad explanation, I was in a hurry. Sorry.  But I know the answer is correct.

Answer:

A (5,-3) does not belong

B (-2,4) does not belong

C (0,0) belongs

D (2,1) belongs

E (-5,2.5) does not belong

Step-by-step explanation:

To find the answer, you'll need to know

what is the number in half? If (x,y) is like

10,5 then that will belong.

Answer:

tbh I think its the middle one

Step-by-step explanation:

Answer:

2,3,1

Step-by-step explanation:

1 => 25-3=22

2 => 5-6 = -1

3 => 5- -3 = 8

I'm sorry if I get this wrong, but there isn't enough evidence.

If we think about the shorter side being 4.2 cm, then just divide 33.6 by 4.2 to give it a ratio. 33.6 / 4.2 is 8. The ratio of the scale drawing to the actual playground would be 1 : 8.

The longer side is 10.5, so just multiply that by 8. You'd get 84 meters. The only part left is getting the area.

Multiply 84 x 33.6 and you'd get 2822.4

The answer would be 2,822.4 squared.

Answer:

The ticket increased 57% of its original price

The baggage price was 44.5 increased 0.11% and then became 50

Step-by-step explanation:

So if the amount was 200 and now is 350, we should use division.

200 ÷ 350 = 0.5714285714285714 which you can round to 0.57 or as many digits as the question asked for. In thise case I will use 0.57

0.57 converted to percentage is 57%

About the second question

now you know the amount after increase and the percentage. So all you have to do is reverse.

11% = 0.11

0.11  ✕ 50 = 5.5    

this means the price increased 5.5

50 - 5.5 = 44.5

Answer:

Step-by-step explanation:

yes i think so because from point d to point s it’s 4 and then from a to l it’s the same length so i do think it would be 8. 4+4 is 8

Answer:

hypotenuse = 4.24

Step-by-step explanation:

sin θ = opposite / hypotenuse

sin 45 = 3[tex]\sqrt{2}[/tex]/ hypotenuse

0.707 = 3[tex]\sqrt{2}[/tex]/ hypotenuse

hypotenuse = 4.24

Given:

The parent function is

[tex]f(x)=8x+9[/tex]

To find:

The function after the reflection over the x-axis.

Solution:

We know that, if a function f(x) reflected over x-axis to get the function g(x), then

[tex]g(x)=-f(x)[/tex]

Putting [tex]f(x)=8x+9[/tex], we get

[tex]g(x)=-(8x+9)[/tex]

[tex]g(x)=-8x-9[/tex]

The function after the reflection over the x-axis is [tex]g(x)=-8x-9[/tex].

Therefore, the correct option is B.
