Answer:

x= -3/5

Step-by-step explanation:

2x+21/5=3

2x+21/5-21/5=3-21/5           (subtract 21/5 from both sides)

2x=3-21/5                            (L.C.M=5)

2x= 15-21/5

2x= -6/5

2x/2=-6/5/2                        (divide both sides by 2)

x= -6/5x1/2                          (reciprocal)

x= -6/10

simplify:

x= -3/5

Answer:

5 whole laps + 1/4 of a lap. Or, 5.25 laps

Step-by-step explanation:

We can solve this 2 ways.
First, we can continuous add 4/3rds to itself until we reach 7 miles.

4/3 + 4/3 = 2 2/3
+ 4/3 = 4
+ 4/3 = 5 1/3
+ 4/3 = 6 2/3
Then you see that we are almost at 7. We have 1/3 left until we reach 7. 1/3 is 0.25% of 4/3, so its only 25% of a lap. That plsu the 5 other laps we did would equal 5.25 laps.

An easier way is 7 divided by (4/3), which is 5.25.

Good Luck! Hope this helps.

The ratio of green apples to all apples in the basket is 5:14 and the ratio of red apples to all apples in the basket is 9:14.

According to the question,

We have the following information:

There are five green apples and nine red apples in a basket.

Now, total apples in the basket are (5+9) which is 14.

Now, the ratio of green apples to all apples in the basket:

Number of green apples : total apples in the basket

5:14

Now, the ratio of red apples to all apples in the basket:

Number of red apples : total apples in the basket

9:14

Hence, the ratio of green apples to all apples in the basket is 5:14 and the ratio of red apples to all apples in the basket is 9:14.

The interest amount is $120 when given principal amount $2000, rate of interest per year is 3% and time period is 2 years.

Given that,

p = $2,000, r = 3%, and t = 2 yr.

We have to find the i when i=prt.

Here,

i is interest amount.

p is principal amount.

r is rate of interest per year.

t is time period.

So,

Formula for finding interest amount is

i=prt

So,

i=2000(3/100)(2)

i=20×3×2

i=120

The Fourier series representation of the output y(t) is;

(a) y(t) = 0.097 cos(3πt - 67)

(b) y(t) = 0.097 sin(3πt - 67) + 0.051 cos(6πt + π/4 -78)

Given;

A causal continuous-time LTI system whose input x(t) and output y(t) are related by the following differential equation;

[tex]\frac{d}{dt}y(t) + 4y(t) = x(t)[/tex]

By taking Laplace's Transform;

sY(s) + 4Y(s) = X(s)

Y(s)/X(s) = H(s) = 1/(s + 4)

(a) When input x(t) = cos3πt

∵ ω = 3π

H(jω) = 1/(jω + 4)

H(jω₁) = 1/[tex]\sqrt{w^2+4^2}[/tex] = 0.097

∠H(jω) = -tan⁻¹(ω/4) = -67° = Ф₁

y(t) = H(jω₁)*cos(3πt + Ф₁)

→ y(t) = 0.097 cos(3πt - 67)

(b) When input x(t) = sin3πt + cos(6πt + π/4)

∵ ω = 6π

H(jω) = 1/(jω + 4)

H(jω₂) = 1/[tex]\sqrt{w^2+4^2}[/tex] = 0.051

∠H(jω) = -tan⁻¹(ω/4) = -78° = Ф₂

y(t) = H(jω₁) * sin(3πt + Ф₁) +  H(jω₂) * cos(6πt + π/4 + Ф₂)

→  y(t) = 0.097 sin(3πt - 67) + 0.051 cos(6πt + π/4 -78)

The Fourier series representation of the output y(t) is;

y(t) = 0.097 cos(3πt - 67)

divide both numbers by 2 and there is your answer

The amount after four years is £2649.79 .

Now we know that we need to obtain the rate for the compounding of the money and we need to recall that for the amount, we have;

A = P(1 +r/n)^nt

A = amount

P = principal

r = rate

n = number of times compounded

t = time

For one year in which the interest is compounded annually;

2496.96 = 2448(1 + r)^1

2496.96/ 2448 = (1 + r)

1.02 = 1 + r

r = 1.02 - 1

r = 0.02 or 2%

Now after four years;

A = 2448(1 +  0.02)^4

A = £2649.79

Drake needs 144 ft² (squared feet) of fabric to make the 8 ft long and 18 ft tall sail.

The area (square units) of two lengths is the product of the multiplication of the two lengths.

The area refers to the space occupied by a two-dimensional object or structure.

Areas are stated in square feet to show the squared units occupied by such objects.

The length of a sail = 8 feet

The height of the sail = 18 feet

The square area = 144 ft² (8 x 18)

Thus, Drakes requires a fabric measuring 144 ft² (squared feet) to make the sail.

1. The number of sides of the polygon is of: 12 sides.

2. The missing exterior angles are of: α = 48.5º.

3. The size of the exterior angle is of 20º, hence the polygon has 18 sides.

A regular polygon is a polygon in which all the sides have the same length.

The relation between the measure of the exterior angles of a regular polygon and the number of sides is given as follows:

Measure of each angle = 360º/number of sides.

For item a, the measure of each angle is of 24º, hence the number of sides is obtained as follows:

24º = 360º/number of sides.

24n = 360

n = 360/24

n = 12 sides.

The sum of the measures of the external angles of a polygon is always of 360º.

Hence, for item 2, the missing angles are obtained as follows:

2α + 90 + 55 + 40 + 78 = 360

2α + 263 = 360

2α = 97

α = 97/2

α = 48.5º.

An interior angle and it's exterior angle are supplementary, hence, for item 13, the measure of the exterior angle is of:

Exterior angle = 180º - 160º = 20º.

Then the number of sides of  the polygon is obtained as follows:

20n = 360

n = 360/20

n = 18 sides.

The proof is sufficient evidence or a sufficient argument for the truth of a proposition. The concept applies in a variety of disciplines, with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent.

if our test statistic is: positive and greater than the critical value, then we have sufficient evidence to reject the null hypothesis and accept the alternative hypothesis. positive and lower than or equal to the critical value, we must accept the null hypothesis.
