What is this answer? 8(x-5)

Answer:

2950 [Starting from 2,000 bacteria.]

Step-by-step explanation:

400/8 = 50

Bacteria grown/time = bacteria per hour

19x50 = 950

time x bacteria per hour = bacteria grown

2000 + 950

bacteria started + bacteria grown

Step-by-step explanation:

The bases of a trapezoid have lengths 10 and 18. If the height of the trapezoid is 6, what is the area of the trapezoid

The area of a trapezoid is given as:

1/2(b1 + b) × h

Where:

b1 = Base 1 = 10

b2= Base 2 = 18

h = Height = 6

Therefore, the area of a trapezoid =

1/2 (10 + 18) × 6

= 28/2 × 6

= 84

Therefore, the area of the trapezoid = 84

Step-by-step explanation:

13 blocks × (1 mile)/(20 blocks) = 13/20 mile = 0.65 mile

Tracker is inaccurate

The fitness tracker is inaccurate.

A ratio indicates the number of times one number contains another.

Given that, there are 20 blocks per mile.

20 blocks = 1 mile

1 block = (1/20) mile

13 block = (13/20) mile

13 block = 0.65 mile

Therefore, Tara walks 0.65 miles, not 0.71 miles.

Hence, the fitness tracker is inaccurate.

Given:

The value of car before two years = £10000

The value of the car decreases by 5% each year.

To find:

The present value of the car.

Solution:

The exponential decay model for present value is

[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]

Where, a is the initial value, r is the rate of decay and t is time in years.

Putting P=10000, r=5 and t 2, we get

[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]

[tex]y=10000\left(1-0.05\right)^2[/tex]

[tex]y=10000\left(0.95\right)^2[/tex]

On further simplification, we get

[tex]y=10000(0.95)(0.95)[/tex]

[tex]y=9025[/tex]

Therefore, the present value of the car is £9025.

Area of the square = 225.0 in²

Step-by-step explanation:

Given polygon is a regular polygon that means given quadrilateral has all sides equal in measure.

And a quadrilateral with all sides equal is known to be a square.

Therefore, area of a square = (Side)²

                                              = (15)²

                                              = 225

                                              ≈ 225.0 in²

Answer:

[tex]\frac{2}{81}[/tex]

Step-by-step explanation:

There is a common ratio between consecutive terms in the sequence

r = [tex]\frac{-\frac{2}{3} }{2}[/tex] = [tex]\frac{\frac{2}{9} }{-\frac{2}{3} }[/tex] = [tex]\frac{-\frac{2}{27} }{\frac{2}{9} }[/tex] = - [tex]\frac{1}{3}[/tex]

To find a term in the sequence multiply the previous term by - [tex]\frac{1}{3}[/tex] , then

a₅ = - [tex]\frac{1}{3}[/tex] × a₄ = - [tex]\frac{1}{3}[/tex] × - [tex]\frac{2}{27}[/tex] = [tex]\frac{2}{81}[/tex]

By the interior angle theorem of triangles, the value of x is 5°.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sum of the interior angles in a triangle is 180°.

Given, In a triangle DEF the measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x .

Therefore, m∠D + m∠E + m∠F = 180°.

50° + 80° + 10x = 180°.

10x = 180° - 130°.

10x = 50°.

x = 5°.

So, The value of x is 5°.

The coordinate point of intersection on the graph will be at (1.5, 4.5)

Given the equations Dimitri wrote expressd as:

y = 3x

y = x + 3

Since they are both y-values, we can equate the right hand side to have:

3x = x + 3

3x - x = 3

2x = 3

x = 3/2

x = 1.5

Get the value of y:

y = 3x

y = 3(1.5

y = 4.5

Hence the coordinate point of intersection on the graph will be at (1.5, 4.5)

The set {126, 168, 189} has  21 as a common factor.

The set{154, 231} has  11 as a common factor.

If a number m is completely divisible by number n. Then number n will be the one factor of number m.

(a). Given set of number is, {126, 168, 189}

Now check,  21 is a common factor or not.

 [tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]

It is observed that all numbers are completely divisible by 21.

So that , 21 is common factor.

(b). Given set of number is, {154, 231}

Answer: $3,000

Step-by-step explanation:

The cost for a single person is:

Travel      £150

Hotel       £50 for each day

Spending money       £250

Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:

= 150 + (50 * 7) + 250

= 150 + 350 + 250

= $750

There are 4 people so the total cost will be:

= 750 * 4 people

= $3,000
