Answer:

Age of Peter = 3 year

Step-by-step explanation:

Given:

Peter is 8 years younger than Jonne

Assume;

Age of Jonne = a

So,

Age of Peter = a - 8

After 5 years,

2[a - 8 + 5] = a + 5

2a - 6 = a + 5

a = 11

Age of Jonne = 11

Age of Peter = 11 - 8

Age of Peter = 3 year

Answer:

Option A

Step-by-step explanation:

The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.

So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.

Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:

[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]

The end result matches with the equation determined before, so option A is the answer.  

Answer:

382 inches

Step-by-step explanation:

Given that :

The size of the soccer ball that Adrian and Violetta got is = 4

The diameter of the soccer ball is = 9 inches

Therefore, the radius of the soccer ball is, r = [tex]$\frac{9}{2}$[/tex]  inches

So the volume of the soccer ball is :

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

[tex]V = \frac{4}{3} \times \frac{22}{7} \times \left(\frac{9}{2}\right)^3[/tex]

[tex]V = \frac{4}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times \frac{9}{2}[/tex]

V ≈ 382 inches

Answer:

258 miles

Step-by-step explanation:

y = # miles truck driven

m = each mile driven

y = 14.95 + 0.97m

265.21 = 14.95 + 0.97m

250.26 = 0.97m

m = 258

Step-by-step explanation:

Using an exponential function, it is found that $11,747 will be in the account after 4 years.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

In this problem, considering the initial investment of $7,400, and the fact that it doubles every 6 years, the equation is given by:

[tex]A(t) = 7400(2)^{\frac{t}{6}}[/tex]

Hence the amount in 4 years is given by:

[tex]A(4) = 7400(2)^{\frac{4}{6}} = 11747[/tex]

Answer:

We have sin² x + cos² x =1 for all real x.

Therefore, sin² x = 1 – cos² x = 1 – (8/17)² = 1 – 64/289 = 225/289 = (15/17)².

However, remember that if x² = a², then x can be +a or –a.

Therefore, sin x can be either –15/17 or +15/17.

Everyone but Anirban so far has forgotten the negative solution.

Step-by-step explanation:

Given that sinθ=817 and cosθ<0 , we have: cosθ=−√1−sin2θ. cosθ=−√1−(817)2. cosθ=−√1−64289.

Answer:

680 km/hr

Step-by-step explanation:

[tex]\frac{2720 km}{4 hr}[/tex]=680 km/hr

Answer:

680 km/hr

Step-by-step explanation:

Given,

Distance ( d ) = 2720 km

Time ( t ) = 4 hours

To find : -

Average speed = ?

Formula : -

Average speed = d / t

Average speed

= 2720 / 4

= 680 km/h

im doing this problem right now---

ok so a1=256 a2=64 a3=15 a4=4... find a9

the sequence divides by 1/4 every term

an=a1*r^n-1

an=(256)*(1/4)^n-1

replace n with 9

A9=(256)*(1/4)^9-1

A9=(256)*(1/4)^8

=(256)*(1/4)

A9=64^8

1/256 or a9= 0.00390625

Answer:

$39.04

Step-by-step explanation:

1.Approach

To solve this problem, one must first find the amount of tip that was left, then add the value to the cost of the meal. The amount of tip given can be found by dividing the percent value of the tip by (100) and then multiplying the result by the price of the meal.

2.Find the amount of tip

To find the amount of tip that was left, divide the percent value of the tip by (100). This technique converts the percent into a decimal. After doing so,  multiply the result by the cost of the meal.

Tip as a percent: 15%

Tip as a decimal: 0.15

Amount of tip left:

33.95 * 0.15 = 5.0925

Round the result

~5.09

3.Find the total bill

Disincluding the tax, one now has to add the tip to the cost of the meal to find the total amount paid.

(tip) + (price)

= (5.09) + (33.95)

= (39.04)

Answer:

The equation is ;

4x - y = 13

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from what we are given, let us write the second equation in the general form

x + 4y = 10

4y = -x + 20

y = -1/4x + 20/4

y = -1/4x + 5

mathematically, when two lines are perpendicular, the product of their slope is -1

So for the second line with slope m2

m2 * -1/4 = -1

m2 = 4

So, using the general form, we have the equation as;

y = 4x + b

To get the value of b, we substitute the coordinates of the given point (3,-1)

-1 = 4(3) + b

-1 = 12 + b

b = -1-12

b = -13

So the equation is;

y = 4x - 13 which can be rewritten as;

4x-y = 13

Answer:

Exceeded by 145 dollars.

Step-by-step explanation:

First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.

Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.

Subtract 500 from 645 and you get the answer of 145.

So they exceeded 145 dollars.

Answer:

Median without outlier should be 40

For the bottom questions, it should go:

Decreases the mean, does not change the median, does not change the mode

It's decreasing the mean because it goes from 44.7 to 39

Median w/ and without outlier is both 40

Mode also stays the same w/ or without the outlier, which is 96
