Answer:

Xavier will not be able to qualify because the speed required for him to qualify is greater than the speed at which he runs

Step-by-step explanation:

Here, we want to know if Xavier will be able to qualify or not

His constant speed is 5/3 m/s

Now to win , he needs a speed of 100 m/55 sec = 20/11 m/s

So now, we need to know the bigger fraction between the two

Mathematically, that will be

5/3 - 20/11 = (55-60)/11 = -5/11

As we can see, the required speed is greater than what he can run

So this means that he will not be able to qualify

bruh its so blury. make the same question with a different angle

Answer:

x = 0.5

Step-by-step explanation:

Given

- 8.25x + 12 - 1.75x = 10.5x + 1.75 , that is

- 10x + 12 = 10.5x + 1.75 ( subtract 10.5x from both sides )

- 20.5x + 12 = 1.75 ( subtract 12 from both sides )

- 20.5x = - 10.25 ( divide both sides by - 20.5 )

x = 0.5

Answer:

she has 45 dollars left

Answer:

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

Step-by-step explanation:

We need to find mistake make in work below:

[tex](-2x^4)^4=-16x^{16}[/tex]

The mistake here is when we have even power, the negative sign gets positive i.e [tex](-a)^m=a^m[/tex] if m is even

so, in our case it would be:

[tex](-2x^4)^4=16x^{16}[/tex]

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

Answer:

a). f(0) = 4

b). f(6) = 8

Step-by-step explanation:

a). When x < 5, piecewise function to be considered,

f(x) = x + 4

Since, x = 0 is less than x = 5

f(0) = 0 + 4

f(0) = 4

b). When 5 ≤ x < 7,

Piecewise function to be considered,

f(x) = 8

Therefore, for x = 6,

f(6) = 8

Answer:

£30

Step-by-step explanation:

→ Model the situation in terms of x

Richard = x, Natasha = 3x and Krutika = 6x

→ Now put the values into ratio form

6x : 3x : x = 50

→ Collect the x terms

10x = 50

→ Divide both sides by 10 to isolate

x = 5

→ Substitute x = 5 into Krutika

6 × 5 = 30

Answer:

£30

Step-by-step explanation:

Let's break down the information given to help us find how much Krutika gets.

"Natasha gets three times as much as Richard" - We can express the value that Natasha gets as [tex]3r[/tex] in terms of what Richard gets.

"Krutika gets twice as much as Natasha" - We can express this as [tex]2(3r)[/tex] which equals [tex]6r[/tex].

We know that the total money is £50, so we can write the equation:

[tex]r+3r+6r=50[/tex]

[tex]10r = 50[/tex]

[tex]r=5[/tex]

∴ Richard gets £5.

Since the money Krutika gets can be expressed as [tex]6r[/tex]:

[tex]6(5) = 30[/tex]

∴ Krutika gets £30.

Answer:

In total 177 more students enrolled this year.

Step-by-step explanation:

First get the sum of the students who enrolled in 1995, then the sum of 2005 and then subtract the sums.

Answer:

177 more students

Step-by-step explanation:

1995 had 65 students enrolled

females - 23 males - 42

23 + 42 = 65

2005 had 242 students enrolled

113 + 129 = 242

now to get how many more, you'll want to subtract

242 - 65 = 177

we know this is correct by adding 65 to 177

177 + 65 = 242

either way our answers will be the same

Hope this helps you!

6/2=3 so slope is 3.

Answer:

3 = x

Step-by-step explanation:

To simplify this equation, combine like terms:

3 = x

Answer:

Yeah i have no idea

Step-by-step explanation:

Can i have brainliest???

The slope will be 0.05.

        y = mx + c

      [m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

        [c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

       Other possible equations of lines are -

We have a cell phone company charges $40 plus 0.05 per text

We can write the general equation for the cell phone as -

y = 0.05x + 40

Now, we can compare with the general equation of line as -

m = 0.05

Therefore, the slope will be 0.05.

Answer:

answer is 6 cm, 7cm, 12 cm

Step-by-step explanation:

the rule is that the sum of any two sides of a triangle must be greater than the 1 one side

Answer:

6 cm, 7 cm, 12 cm

Step-by-step explanation:

Answer:

Steps in order will be

[tex]1. y=\sqrt{7x-21}\\2. y^2=7x-21 \\ 3. y^2=7(x-3)\\4. \frac{y^2}{7}=x-3\\ 5. x=\frac{y^2}{7}+3\\6. f^{-1}(x)=\frac{1}{7}x^2+3 \:where\: x\geq 0[/tex]

Step-by-step explanation:

Consider the function [tex]f(x)=\sqrt{7x-21}[/tex]

We need to find [tex]f^{-1}(x)[/tex]

For finding [tex]f^{-1}(x)[/tex]  replace f(x) with y

Step 1: Replace f(x) with y

[tex]y=\sqrt{7x-21}[/tex]

Now, solve for x

Step 2: Taking square on left side

[tex]y^2=(\sqrt{7x-21})^2\\y^2=7x-21[/tex]

Step 3 : take 7 common

[tex]y^2=7(x-3)[/tex]

Step 4 : Divide both sides by 7

[tex]\frac{y^2}{7}=x-3[/tex]

Step 5: Add 3 on both sides

[tex]\frac{y^2}{7}+3=x-3+3\\x=\frac{y^2}{7}+3[/tex]

Step 6: Replace x with y and x with [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x)=\frac{1}{7}x^2+3[/tex] where x≥0

Steps in order will be

[tex]1. y=\sqrt{7x-21}\\2. y^2=7x-21 \\ 3. y^2=7(x-3)\\4. \frac{y^2}{7}=x-3\\ 5. x=\frac{y^2}{7}+3\\6. f^{-1}(x)=\frac{1}{7}x^2+3 \:where\: x\geq 0[/tex]

Answer:

Step-by-step explanation:

The amount of money Robert has after 1 year is; $2495.

We are told that Robert came up with the following expression 45w + 155.

where w is the number of weeks that he has been saving.

The equation above represents the amount he will have in his bank account.

Now, 1 year has 52 weeks. Thus, the amount he would have saved in 52 weeks is;

45(52) + 155 = $2495

Thus, we conclude that the amount of money Robert has after 1 year is $2495.
