The gradient will only be equal to 3 if the value of d is 7.

If we have two points (a, b) and (c, d), the gradient of the segment with these endpoints is:

G = (d - b)/(c - a)

Here the endpoints are (5, 9) and (d, 15), and the gradient is 3, so we can write the equation:

3 = (15 - 9)/(d - 5)

3*(d - 5) = 6

3d - 15 = 6

3d = 15 + 6 = 21

d = 21/3

d = 7

The value of d is 7.

The value of the angles that are intersected by BC are m/ABC is 35° and m/DBC is 43°

In the given figure the angle ∠ABD is intersected by the straight line BC such that two new angles are formed ,∠ABC and ∠ADC  .

Now from the properties of angles on a 2-dimensional plane we can see that :

m ∠ABC + m ∠ADC  = m ∠ABD

The values of the angles given are:

m ∠ABC = 5x - 5

m ∠ADC = 5x + 3

m ∠ABD = 78°

now we put these above values in the equation:

(5x - 5) + (5x + 3) = 78

or, 10 x - 2 = 78

or, 10 x = 80

or , x = 8

m ∠ABC = 5×8 - 5 = 35°

m ∠ADC = 5×8 + 3 = 43°

The length of side CA is right triangle ABC, 8.86 centimeters

In this question, we have been given triangle ABC has a right angle at C.

This means, AB is the hypotenuse of right triangle ABC.

measure of angle A = 41 degrees

and the length of side BC = 7.7 centimeters

We need to find length of CA

Consider sine of angle A.

sin(A) = opposite side/hypotenuse

sin(41°) = BC/AB

0.6561 = 7.7 / AB

AB = 7.7/0.6561

AB = 11.74

Applying Pythagoras theorem,

AB² = BC² + AC²

11.74² = 7.7² + AC²

AC² = 11.74² - 7.7²

AC = √(78.53)

AC = 8.86 centimeters

Red paint  = 12.5 gallons

Blue paint = 7.5 gallons

Step-by-step explanation:

The given ratio of red paint to blue paint is:

Let x be the number of gallons of purple paint.

Therefore, the expression for each color of paint needed per x gallons of purple paint is:

[tex]\implies \textsf{Red\;paint $=\dfrac{5}{8}x$}[/tex]

[tex]\implies \textsf{Blue\;paint $=\dfrac{3}{8}x$}[/tex]

To calculate the number of gallons of red and blue paint needed to make 20 gallons of purple paint, substitute x = 20 into the found expressions:

[tex]\implies \textsf{Red\;paint $=\dfrac{5}{8} \times 20=\dfrac{100}{8}=12.5$}[/tex]

[tex]\implies \textsf{Blue\;paint $=\dfrac{3}{8}\times 20=\dfrac{60}{8}=7.5$}[/tex]

Therefore, the number of gallons of paint that should be used are:

The sides and angles of the right triangle are as follows:

A right tangle triangle is a triangle that has on e of its angles as 90 degrees. The sides of a right triangle can be named based on the position of the angles.

The sides includes opposite side, adjacent side and hypotenuse side. The longest side of a right angle triangle is the hypotenuse side.

The sides of the right angle triangle can be found using trigonometric ratios as follows:

sin 85 = opposite / hypotenuse

sin 85 = a / 8

a = 8 sin 85

a = 7.96955758473

a = 8.0

cos 85 = adjacent / hypotenuse

cos 85 = b / 8

b = 8 cos 85

b = 0.69724594198

b = 0.7 units

The y-intercept is y = 3, and this is the initial height of the ball, and the maximum height is y = 19

The y-intercept is what we get when we evaluate in x = 0, then:

y = -0.25*x² + 4x + 3

replacing x by zero we get:

y = -0.25*0² + 4*0 + 3 = 3

The y-intercept is y = 3.

The maximum height is at the vertex, we know this because the leading coefficient is negative, which means that the parabola opens down.

The vertex is at:

The additional number of days that is required to complete the rest of the work in mixed fraction is equal to 4 4/11 days.

First of all, we would determine the number of work left for Ann after two (2) working days:

In one (1) day, the amount of work that would be done by Ann alone is given by 1/10 days. Therefore, the amount of work that would be done by Ann alone in two (2) days is given by 2/10 or 1/5 days.

For the number of work left, we have:

Work left = 1 - 1/5

Work left = 4/5 days.

Similarly, the amount of work that would be done by Ben alone in one (1) day is given by 1/12 days.

Therefore, the combined work rate of both Ann and Ben is given by:

Combined work rate = 4/5 + 1/12

Combined work rate = 11/60

For the additional number of days required to complete the rest of the work, we have:

Additional days = 4/5 ÷ 11/60

When the radius is 9cm, it increases at a rate of 0.06 cm per second.

We assume the ballon is a perfect sphere. Remember that the volume of a sphere as a function of the radius is given by:

V = (4/3)*3.14*(R)³

When the radius is R = 9cm, the volume is:

V =  (4/3)*3.14*(9cm)³ = 3,052.08 cm³

Isolating the radius as a function of the volume, we get:

R = ∛((3/4*3.14)*V)

And we know that the volume increases at a constant rate of 6cm³/s, if we assume that the initial volume is 3,052.08 cm³ then we can write the radius as a function of time as:

R(t) = ∛((3/4*3.14)*(3,052.08 cm³ + 6cm³/s*t))

Where t is the time in seconds.

Now we need to differentiate this and evaluate in t = 0.

R'(t) = (1/3)*(3/4*3.14)*(3,052.08 cm³ + 6cm³/s*t)^(-2/3)* (6cm³/s*3/4*3.14)

Evaluating in t = 0 we get:

R'(0) = (1/3)*(3/4*3.14)*(3,052.08 cm³ + 6cm³/s*0)^(-2/3)* (6cm³/s*3/4*3.14)

       =  (1/3)*(3/4*3.14)*(3,052.08 cm³)^(-2/3)* (6cm³/s*3/4*3.14) = 0.06 cm/s

1. The unpaid balance after 12 months of paying $546.61 for borrowing $81,000 for 27 years at 6.8% is $79,915.29.

2. During this period, the interest she paid was $5,474.61.

The total payment made, including interest and principal, for 12 months is the product of the monthly payments and 12 months.

From the amortization schedule from an online finance calculator at month 12, we can deduce that the loan balance is $79,915.29.

When this balance is subtracted from the loan, the difference is the principal repayment so far.

If one card is drawn randomly from a deck, then the probability that it is not a face card is 76.9%

Probability

Probability refers the possible way of getting the required event.

Given,

A standard deck of cards has 52 cards of four different suits (diamonds, spades, hearts, clubs). Each suit consists of numbered cards 1 (Ace) to 10, followed by Jack, Queen and King (face cards).

Here we need to find the probability of getting not a face card and we have to round off the resulting value to the tenth percent.

We know that,

Total number of cards = 52

Number of suits = 4

Number of cards in each suit = 13

Number of face cards in each suit = 3

Therefore, the total number of face cards in the deck is calculated s,

=> 3 x 4

=> 12

Therefore, the probability of getting not a face card is

=> (52 - 12)/52

=> 40/52

When we simplify this one then we get,
