Answer: 1.25 litres

Step-by-step explanation:

Two litres of paint is sufficient to paint  1 ⅗  doors.

To find out the amount of paint needed to paint one door, you can use direct proportion:

2 litres           :              1 ⅗  door

x                                    1 door

Cross multiply to get:

1 ⅗ x = 2

x = 2 /  1 ⅗

x = 2 ÷ 8/5

x = 2 * 5/8

x = 1.25 litres

The Indapendent virable is: t

Noah took 4 hours to walk 12 miles

(7 1/2, 2 1/2)

Step-by-step explanation:

I hope this is right!

The point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).

Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.

Here,
The independent variable in this situation is time (t).

Point (12, 4) represents that Noah walked for 4 miles in 12 hours.

To find the point that represents the time it took to walk 7 ½ miles, we need to solve for t in the equation ⅓ d = t.

Substituting d = 7.5, we get:

⅓ (7.5) = t

Simplifying, we get:

t = 2.5

Therefore, the point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).

Answer:

x=3

Step-by-step explanation:

First would need to convert the radical into a number.

And since if you have a perfect square of a radical it goes outside the square root sign, you would take the 3 and square it to make 9 and then take the 2 inside the square root sign and multiply so you have the square root of 18|

Since we have [tex]\sqrt{18}[/tex] as the Leg c we would need to square it, squaring a square root sign would just cause them to be cancelled out and you being left with 18, afterwards find the square of 3, which is 9

18-9=9

square root of 9 = 3

Answer:

22,000 miles

Step-by-step explanation:

Circumference of a circle: 2πr (r is the radius)

Substitute the length of the radius given, which is 3500. Also, substitute the approximate value of π, which is 3.14.

Circumference = 2 * 3.14 * 3500

Circumference = 21980

This rounds to about 22,000, so the answer is 22,000 miles.

I hope this helps! Feel free to ask any questions!

Answer: 22,000 miles

Step-by-step explanation:

Circumference of circle = 2πr

2 × 22/7 × 3500

22/7 × 3500 = 11000

2 × 11000 = 22000

The circumference would be 22,000 miles.

OR

Circumference of circle = 2πr

2 × 3.14 × 3500

6.28 × 3500 = 21,980

21980 to the nearest 1000 is 22000

The circumference would be approximately 22,000 miles.

Step-by-step explanation:

.08 x 100 = 8%

Given:

The equation is:

[tex]3^x\times 9=3^{2n-1}[/tex]

To find:

The value of n in terms of x.

Solution:

We have,

[tex]3^x\times 9=3^{2n-1}[/tex]

It can be written as

[tex]3^x\times 3^2=3^{2n-1}[/tex]

[tex]3^{x+2}=3^{2n-1}[/tex]                [tex][\because a^ma^n=a^{m+n}][/tex]

On comparing the exponents, we get

[tex]x+2=2n-1[/tex]

Add 1 on both sides.

[tex]x+2+1=2n-1+1[/tex]

[tex]x+3=2n[/tex]

Divide both sides by 2.

[tex]\dfrac{x+3}{2}=n[/tex]

Therefore, the value of n is terms of x is [tex]n=\dfrac{x+3}{2}[/tex].

Tax returns aren't gifts. They're refunds you get because the IRS withdrew too much from your paychecks or had withdrawals from other investment accounts. While it may seem like a great thing to have a tax return come each April, you pay for it the other 11 months of the year.

“A refund means you're giving your cash flow and income to the government in an interest-free loan.” The interest rate on one-year U.S. bonds is around 1.5%, so any interest the government could hypothetically pay on that loan would be very small: about $15 for every $1,000 in your refund.

Correct choice is B

Answer:

=50.29

Step-by-step explanation:

The perimeter of a circle is also called the circumference

C = 2 * pi *r

25 1/7 = 2 * 22/7 *r

Rewriting as an improper fraction on the left

(25*7 +1)/7 = 44/7 *r

176/7 = 44/7 r

Multiplying each side by 7/44

7/44 *176/7 = 7/44 *44/7 r

4 = r

We can now find the area by

A = pi r^2

A = (22/7) * 4^2

A = 22/7 * 16

  =352/7

Rounding to the nearest hundredth

Answer:

Drone will take 0.25 hectare per minute to scan the area.

Step-by-step explanation:

By using unitary method,

A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.

Area scanned by the drone in 1 minute = [tex]\frac{\text{Total area scanned}}{\text{Total time taken}}[/tex]

                                                                 = [tex]\frac{0.5}{2}[/tex]

                                                                 = 0.25 hectare per minute

Therefore, drone will take 0.25 hectare per minute to scan the area.

Also,the z-matrix Dz is given by;

(3 4 18)

(2 -1 13)

(5 -2 -20)

Determinant of the coefficient matrix from online determinant calculator is;

D = 136

Determinant of the x-matrix from online determinant calculator is; Dx = 92

Determinant of the y-matrix from online determinant calculator is; Dy = 696

Determinant of the z-matrix from online determinant calculator is; Dz = 576

From crammers rule;

x = Dx/D = 92/136

y = Dy/D = 696/136

z = Dz/D = 576/136

Answer:

∠A = 116°

∠B = 116°

∠C = 64°

Step-by-step explanation:

since it is an isosceles trapezoid, ∠C = ∠D = 64°

∠A would be same side interior to ∠D so it would be 180° - 64° = 116°

∠B = ∠A = 116°

The  measure of each angle in the isosceles trapezoid are; ∠A = 116°

∠B = 116° and ∠C = 64°

Due to the figure being isosceles trapezoid, it is symmetric.

Isosceles trapezoid has its two rest sides(which aren't necessary parallel) are of equal length.

Since it is an isosceles trapezoid, ∠C = ∠D = 64°

Here we can use the  symmetric property of the isosceles trapezoid and the fact that a triangle has sum of its angles as 180°

We have ∠A that would be same side interior to ∠D

Thus, it would be 180° - 64° = 116°

∠B = ∠A = 116°

Step-by-step explanation:

Answer:

If the weight of the equipment is 20oz, then the total weight of the package is 23 oz.

Step-by-step explanation:

The value of the variable p determines the package's overall weight. The true statement in the scenario given is provided by: Option 3: If the equipment weighs 20 oz, the package will weigh a total of 23 oz.

To examine if there is a relationship between the two variables in the tabular data, we can try fitting a curve to the data between the two variables.

Depending on the situation, there may be an exact relationship, a loose connection (measured by correlation or polynomial regression that fits), or even complete independence.

For the given case, two variables in consideration are:

w = weight of equipment (oz, it means weight is calculated in oz units).

p = total weight of package (in oz)

From the table, we can see that for each value of w, the value of p is 3 more than whatever value of w is there.

Thus, the correct option is 3.
