Answer:

Nina's rate in MPH:  12.706 miles per hour

Nina is faster than Sophia.

Step-by-step explanation:

For this problem, we will convert feet per second into miles per hour, and then compare Nina's rate to Sophia's rate.

We are given Nina rides at 63360 feet in 3400 seconds.  To convert this to miles per hour, we need to know that there are 5280 feet in 1 mile, and 3600 seconds in 1 hour.  Now that we now these conversions, let's find the rate in miles per hour.

(63360 feet / 3400 seconds) * (1 mile / 5280 feet) * (3600 seconds / 1 hour) = 12.706 miles per hour.

So we know that Nina rides her bike at 12.706 miles per hour and are given that Sophia rides her bike in 10 miles in 1 hour.

With this, we can say Nina rides faster than Sophia by 2.706 miles per hour (12.706 - 10).

The distance is [tex]sqrt{10000+484t^2}[/tex]

Step-by-step explanation:

Given that,

Altitude = 100 feet

Average speed = 15 miles/ hour

We need to calculate the speed in feet/sec

Using formula for speed

[tex]v=15 miles/hour[/tex]

[tex]v=15\times 1.46667\ ft/sec[/tex]

[tex]v=22\ ft/sec[/tex]

We need to calculate the distance in t sec

Using formula of speed

[tex]v =\dfrac{d}{t}[/tex]

Put the value into the formula

[tex]22=\dfrac{d}{t}[/tex]

[tex]d=22t[/tex]

According to figure,

We need to calculate the distance

Using pythagorean theorem

[tex]AC=\sqrt{(AB)^2+(BC)^2}[/tex]

Put the value into the formula

[tex]d=\sqrt{100^2+(22t)^2[/tex]

[tex]d=\sqrt{10000+484t^2}[/tex]

Hence, The distance is [tex]sqrt{10000+484t^2}[/tex]

Answer:

The answer is below

Step-by-step explanation:

Let us assume that the age of Greg's brother (Gabe) is x years, and let Greg's age by y years. Since Greg is 10 years older than his brother gabe, then:

y = x + 10           (1)

Also. Greg is 3 times as old as Gabe, hence:

y = 3x                 (2)

From equation 1 and equation 2:

y = x + 10 = 3x

Hence:

3x = x + 10

Subtracting x from both sides gives:

3x - x = x + 10 - x

2x = 10

Dividing by 2:

2x/2 = 10/2

x = 5 years

y = x + 10 = 5 + 10 = 15 years

Therefore Gabe is 5 years old and Greg is 15 years old

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 80cm

The length is 4 inches longer than twice the width is written as

l = 4 + 2w

Substitute this into the formula and solve for the width

That's

80 = 2( 4 + 2w) + 2w

80 = 8 + 4w + 2w

6w = 80 - 8

6w = 72

Divide both sides by 6

w = 12 cm

Substitute w = 12 cm into l = 4 + 2w

That's

l = 4 + 2(12)

l = 4 + 24

l = 28cm

Therefore

length = 28 cm

width = 12 cm

Hope this helps you

Answer:

P(prize)= 2/7

Step-by-step explanation:

The probability of getting a prize can be found by dividing the number of favorable outcomes by the total number of outcomes.

P (prize) = favorable / total

The favorable outcome is a prize and there are 10 prizes.

P (prize) = 10 / total

There are 10 prizes and 25 blanks. Add 10 and 25.

10 prizes + 25 blanks= 35 total outcomes

P (prize)= 10/35

This fraction can be simplified. Both the numerator and denominator can be evenly divided by 5.

P(prize)= (10/5) / (35/5)

P(prize) = 2 / (35/5)

P(prize)= 2/7

The probability of receiving a prize is 2/7

Answer:

100/7.5

Step-by-step explanation:

It takes 13.3 s to reach 100 meter.

The formula for the time it takes to travel a distance of d at an average speed is t = d / v

t = 100 / 7.5

t = 13.33

To calculate time, divide the distance by using pace. To get the gap, multiply pace by time. you could see those equations simplified as s = d / t, wherein s is speed, d is distance, and t is time.

Question 14, Part (i)

Focus on quadrilateral ABCD. The interior angles add to 360 (this is true for any quadrilateral), so,

A+B+C+D = 360

A+90+C+90 = 360

A+C+180 = 360

A+C = 360-180

A+C = 180

Since angles A and C add to 180, this shows they are supplementary. This is the same as saying angles 2 and 3 are supplementary.

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

Question 14, Part (ii)

Let

x = measure of angle 1

y = measure of angle 2

z = measure of angle 3

Back in part (i) above, we showed that y + z = 180

Note that angles 1 and 2 are adjacent to form a straight line, so we can say

x+y = 180

-------

We have the two equations x+y = 180 and y+z = 180 to form this system of equations

[tex]\begin{cases}x+y = 180\\y+z = 180\end{cases}[/tex]

Which is really the same as this system

[tex]\begin{cases}x+y+0 = 180\\0+y+z = 180\end{cases}[/tex]

The 0s help align the y terms up. Subtracting straight down leads to the equation x-z = 0 and we can solve to get x = z. Therefore showing that angle 1 and angle 3 are congruent. We could also use the substitution rule to end up with x = z as well.

Answer:

Step-by-step explanation:

The first step in solving an equation is to look at it. Identify where the variable is that you're interested in, and see what operations are being performed on that variable.

Here, the variable w has 1 added to it, and the sum is multiplied by -4. The variable is only on the left side of the equation, and is inside parentheses. Inside parentheses, the coefficient of the variable is 1.

These observations tell you that, in some order, you will need to undo the operations of multiplication and addition, and you will have to eliminate parentheses.

You also observe that the multiplication factor of the parentheses (-4) is a factor of the constant on the right side of the equation (-24). This means you have a couple of options for solving this equation:

The second method is actually faster. We'll illustrate that one first.

__

Divide both sides of the equation by -4 to undo the multiplication by -4.

  -4(w +1)/(-4) = -24/(-4) . . . . . we have indicated the division we want to do

  w +1 = 6 . . . . . . . . . . . . . . . . here is the result of that division

Now, we can add the opposite of +1 to eliminate the constant from the left side. As with all operations on equations, we must do the same thing to both sides. This means we add -1 to both sides of the equation:

  w +1 -1 = 6 -1 . . . . . . we have indicated the addition we want to do

  w = 5 . . . . . . . . . . .  here is the result of that addition

The solution of the equation is ...

  w = 5

__

Often, when parentheses are involved, the numbers are such that the solution method is not as simple as what we just did. In those cases, you would take the approach of eliminating parentheses first. For this equation, it looks like this:

  -4(w +1) = -24 . . . . . . . given

  -4w -4 = -24 . . . . . . . . use the distributive property to eliminate parentheses

We want the variable term by itself, so we need to eliminate the constant -4 that is added on the left. To do that, we add its opposite. This means we add +4 to both sides of the equation.

  -4w -4 +4 = -24 +4 . . . . . . indicating the addition of +4

  -4w = -20 . . . . . . . . . . . . . the result of adding +4

Here, w is multiplied by -4. We want w by itself, so we want to undo that multiplication. That means we want to divide both sides of the equation by -4.

  -4w/(-4) = -20/(-4) . . . . . . indicate the division

  w = 5 . . . . . . . . . . . . . . . . the result of doing the division

The solution of the equation is ...

  w = 5

_____

Our basic approach is to undo the operations done to the variable, in the reverse of the order in which they are done. In that process, we observe the rules of equality: whatever operation you do to one side of the equation must also be done to the other side. (My teacher called this last rule: "keep the equal sign sacred.")

You can always use the distributive property for factoring, collecting terms, or eliminating parentheses.

Answer:

Explained below.

Step-by-step explanation:

Assuming that the question is related to exponents.

Consider the expression: [tex]a^{b}[/tex]

Here,

a = base

b = exponent

Consider that the value of base is a negative term.

Then an even exponent will give a positive result.

And an odd exponent will give a negative result.

Consider the following values of b and suppose that a = -x.

For b = 4,

[tex]a^{b}=(-x)^{4}=(-x)\times (-x)\times (-x)\times (-x)=x[/tex]

For b = 3,

[tex]a^{b}=(-x)^{3}=(-x)\times (-x)\times (-x) = -x[/tex]

Answer:

Sample Response: When evaluating a power with a negative base, the solution is positive or negative depending on whether the exponent is odd or even. If odd, the value will be negative. If even, the value will be positive.
