Triplets Peter, Reeta and Nikita have two ways for getting home from school each day: cycle on a tandem bike or walk. The bike can carry either one or two riders at a time. Regardless of the number of people pedalling, cycling speed is 5 times walking speed. The triplets always leave school at the same time and always use the same path between school and home, whether walking or cycling. The school is 5km from home and their walking speed is 4 kilometres per hour. A On Monday, Nikita and Peter cycle and Reeta walks. On reaching the point four-fifths of the way home the bike gets a puncture, so Nikita and Peter walk the rest of the way home. How far from school is Reeta when the cyclists arrive home?

Answer:

1890 in³

Step-by-step explanation:

The formula to find the volume of a triangular prism: 1/2 x b x h x l, where b is the base, h is the height and l is the length.

1) Substitute the given values in the image into the formula above.

= 1/2 x 18 x 7 x 30

= 1/2 x 126 x 30

= 1/2 x 3780

= 1890

Answer:

x=2

Step-by-step explanation:

To test when the function f(x) over takes the function g(x)

I just plugged in the x values

X f(x) g(x)

1 6 6

2 12 16

3 18 30

4 24 48

We can see from this table that f(x) is greater than g(x) starting from x=2

Therefore I think x=2 is your answer.

Answer:

m∠A = 139°

Step-by-step explanation:

Since knowing that:

Supplementary angles = 180 degree

Thus we put that in both equation:

( 7x - 15 ) + ( 2x - 3 ) = 180

Combine like terms & use inverse operations to find the value of x:

( 7x - 15 ) + ( 2x - 3 ) = 180

9x - 18 = 180

9x - 18 + 18 = 180 + 18

9x  = 198

9x/9 = 198/9

x = 22

Hence,  Angle A will have a measure of 7x - 15 which means  7 ×  22 -15 = 154 - 15 = 139°

m∠A = 139°

The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°

m∠ B = 41°

Check Answer by add 139 and 31 which equal 180

The z-score is the number of standard deviations while the data value is away from the mean.

The Z-score is said to be a kind of numerical measurement that is known to show or depicts the value's relationship one has to the mean of a group of values.

WE have given a mean: 4.9 median: 6 mode: 6 variance: 4

The Z-score is often measured usually in terms of standard deviations that arise from the mean. It means that if a Z-score is 0, it shows that the data point's score is the same as the mean value.

=》 Solution;

solving,

x+2x+6x+18=180

or, 9x + 18 = 180

or, x + 18 = 180/9

or, x + 18 = 20

or, x = 20 - 18

or, x = 2

therefore, value of x is 2

now,

Step-by-step explanation:

Using compound interest, it is found that Claire will have $6,186 in her account when Henry's money has tripled in value.

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

For Henry, we have that r = 0.0675, n = 12. The time it takes for the amount to triple is t when A(t) = 3P, hence:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]3P = P\left(1 + \frac{0.0675}{12}\right)^{12t}[/tex]

[tex](1.005625)^{12t} = 3[/tex]

[tex]\log{(1.005625)^{12t}} = \log{3}[/tex]

[tex]12t\log{(1.005625)} = \log{3}[/tex]

[tex]t = \frac{\log{3}}{12\log{(1.005625)}}[/tex]

t = 16.32.

Then, for Claire, we have that the parameters are as follows:

P = 2300, r = 0.0625, n = 1, t = 16.32.

Hence, the amount is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]A(t) = 2300\left(1 + \frac{0.0625}{1}\right)^{16.32}[/tex]

A(t) = 6186.

Claire will have $6,186 in her account when Henry's money has tripled in value.

Answer:

[tex]v = 2064.2 {cm}^{3} [/tex]

Step-by-step explanation:

we first consider the formula for the volume of a sphere

[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]

we were given diameter of 15.7cm.

we can find the radius by dividing the diameter by 2

because two times a radius makes a diameter.

[tex] \frac{15.7}{2} = 7.9cm[/tex]

we have the radius as 7.9cm.

and we know pi (π) to be 3.14 or 22/7.

but in this case, we use 3.14.

now let's substitute the values in the formula

[tex]v = \frac{4}{3} \times 3.14 \times {7.9}^{3} [/tex]

and we will get

[tex]v = 2064.19 {cm}^{3} [/tex]

but the nearest 10th will be

[tex]v = 2064.2 {cm}^{3} [/tex]

The hypothesis illustrates that C. Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.

Using a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:

tInterval 9.68,1.23,125,0.99

It resulted in 9.68 ± 0.287805.

Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.

Therefore, the researcher failed to reject the null hypothesis.

Complete question:

A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.

A candy company claims that their bags of jellybeans have a mean weight of 9.45 oz. 125 randomly chosen bags of jellybeans were sampled, and it was discovered that their mean weight was 9.68 oz, with a standard deviation of 1.23 oz. Test this hypothesis using a 99% confidence level.

Answer:

[tex]\sf \dfrac{\pi}{2}[/tex]

Step-by-step explanation:

Angles are measured in a counterclockwise direction from the positive x-axis (initial side).

Therefore, if an angle's terminal side is on the positive y-axis, the angle will be 90° or [tex]\sf \dfrac{\pi}{2}[/tex] radians.

See attached diagram for visual explanation.

If the angle was [tex]\pi[/tex] then the terminal side would be on the negative x-axis.

If the angle was [tex]\dfrac32\pi[/tex] then the terminal side would be on the negative y-axis.

If the angle was [tex]2\pi[/tex] then the terminal side would be on the positive x-axis and the angle would be one complete revolution of the circle.

Answer:

x = 2

y = -3

Step-by-step explanation:

y = x - 5  -------------------(I)

x + y = -1 ----------------(II)

Substitute y = x -5 in equation (II)

x + (x - 5) = -1

x + x - 5 = -1   {Combine like terms}

   2x - 5 = -1 {Add 5 to both sides}

        2x  = -1 + 5

         2x = 4 {Divide both sides by 2}

           x = 4/2

x = 2

Substitute x = 2 in equation (I)

y = 2 - 5

y = -3

16, 48, 144

hmmm.

the first thing that comes to mind : it cannot be an addition, as the difference between the 2nd and 3rd numbers is much bigger than the difference between the 1st and 2nd numbers.

so, we try multiplication.

and I see : 16×3 = 48

aha !

48×3 = 144

ok, we found it. the sequence is clearly created by multiplying always the previous number by 3.

so, we have 2 main choices to get the 6th term :

1. simply calculate 144 ×3×3×3 (3 times to get from the 3rd to the 6th term).

2. define the sequence formula and calculate for the 6th term.

1.

144 × 3×3×3 = 144 × 27 = 3,888

2.

a1 = 16

a2 = a1×3 = 16×3 = 48

a3 = a2×3 = a1×3×3 = 16×9 = 144

an = a1 × 3^(n-1) = 16 × 3^(n-1)

a6 = 16 × 3⁵ = 16 × 243 = 3,888

Alright I'm not too sure on what the question is asking for per your instructions, but I've written out my best explanation on how to use distributive property to solve this equation.

So first, what is the process of distributive property? It basically states whatever is in the parenthesis is multiplied by the outside number.

In simpler terms, each character in the parenthesis is multiplied by the number standing outside of the parenthesis.

So we can go...

(3 x 4x) - (3 x 5) = (12x) - (15)

And there's your answer, 12x - 15! Unless you know what x means, you'll probably just stop there.
