jill is 24 years old.

The ratio of vina's age to jill is 7:6 .

      Let vina's age =7x

      let jill's age = 6x

If vina is 4 years older than jill.

Then ,                   7x - 6x = 4

                                  x = 4

Now  vina's age = 7x = 7 * 4 = 28 years

          jill's age = 6x = 6 * 4 = 24 years.

Therefore, jill is 24years old.

Step-by-step explanation:

Tan trigonometric ratio

[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]

where:

Draw a diagram to help visualize the scenario (see attached).

If the angles are complementary, their sum is 90°.

Therefore, let one of the angles be [tex]x[/tex] and the other angle be [tex]90^{\circ}-x[/tex].

Use the tan trig ratio to create two equations with the missing side length.

Right triangle ACD

Given:

Substituting the given values into the tan trig ratio:

[tex]\implies \tan (x)= \dfrac{\textsf{CD}}{9}[/tex]

Right triangle BCD

Given:

Substituting the given values into the tan trig ratio:

[tex]\implies \tan (90^{\circ} - x)= \dfrac{\textsf{CD}}{4}[/tex]

[tex]\textsf{As }\:\tan(90^{\circ} - x)= \cot (x):[/tex]

[tex]\implies \cot(x)= \dfrac{\textsf{CD}}{4}[/tex]

[tex]\implies \dfrac{1}{\tan(x)}= \dfrac{\textsf{CD}}{4}[/tex]

[tex]\implies \tan(x)= \dfrac{4}{\textsf{CD}}[/tex]

Therefore, the two equations are:

  [tex]\textsf{Equation 1}: \quad \tan (x)= \dfrac{\textsf{CD}}{9}[/tex]

  [tex]\textsf{Equation 2}: \quad \tan(x)= \dfrac{4}{\textsf{CD}}[/tex]

Substitute one equation into the other and solve for CD:

[tex]\implies \sf \dfrac{CD}{9}=\dfrac{4}{CD}[/tex]

[tex]\implies \sf CD \cdot CD= 4 \cdot 9[/tex]

[tex]\implies \sf CD^2=36[/tex]

[tex]\implies \sf CD=\sqrt{36}[/tex]

[tex]\implies \sf CD= \pm 6[/tex]

As distance cannot be negative, CD = 6 m only, thus proving that the height of the tower is 6 m.

Answer:

[tex]25a^6-4[/tex]

Step-by-step explanation:

So if you look at the equation, you'll notice it's being multiplied by it's conjugate which can be expressed as: x+a and x-a. See how only the sign changes? Well if remember the differences of squares, it looks like that, because it is. Essentially the difference of squares says that: [tex]a^2-b^2=(a-b)(a+b)[/tex]. So expanding this out will result in [tex](5a^3)^2-(2)^2[/tex] which simplifies to: [tex]25a^6-4[/tex]. If you're confused on how I got 25a^6. Try to think of a^3 as three a's rather than simply an exponent. and since it has a coefficient of 5. 5a^3 is the same as (5 * a * a * a). Now if you square this you have (5 * a * a * a) * (5 * a * a * a). So if you group like terms you'll end up with 6 a's being multiplied by each other (which can be expressed as a^6) and 5 * 5 which is 25.

The multiplication can be transformed into the difference of squares using the rule:(a−b)(a+b)=a²-b² . Gets the square of 2.

(5a³)²-4

Expand (5a³)².

5² (a³)² -4

To raise a power to another power, multiply the exponents. Multiply 3 and 2 to get 6.

The value of  x is 3.711 yd

area = √(s * (s - a) * (s - b) * (s - c))

where

s is the semi perimeter - half of triangle perimeter:

s = (a + b + c) / 2

Using Heron's Formula

area = √(s * (s - a) * (s - b) * (s - c))

area = √(14* (15- 6) * (15 - 14) * (15 - 10))

area = √(14* 9 * 1 * 5))

area = √ 630

area = 25.981 yd²

Now,

area of triangle= 1/2 * b * h

25.981 = 1/2 * 14 *h

51.962 = 14h

Answer:

2.5%

Step-by-step explanation:

656 / 640 = 1.025

1.025 into percent is 102.5%

102.5% - 100% = 2.5

640 + 2.5% of 640 = 656

BOOM

The required value of increase in price is 2.5%.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

Given that,

The cost of ticket at present is £656.

Its cost last year was £640.

Then, the difference between the costs is given as,

656 - 640 = £16

Now, the increase in percentage can be found by taking the ratio of the difference to the last year price and multiplying it by 100 as below,

Percentage increase = 16/640 × 100%

                                   = 2.5%

Hence, the percentage increase in price is 2.5%.

2x-15y = 117 is the simplified form of the equation.

Equation : In a mathematical sentence, if two expressions are present in left and right side of an equal sign, then the mathematical sentence is called an equation.

If, a, b, c be integers and x is x-intercept & y is y-intercept, then ax+by=c is called equation of line.

Given that, the equation of the line that passes through the points (-9,-9)(−9,−9) and (6,-7)(6,−7).

Now, (-9,-9) & (6, -7) have a line through them with slope = (-9+7)/(-9-6) = 2/15

Therefore, (y+7) = 2/15×(x-6)

⇒ y+7 = 2x/15 - 4/5

⇒ y = 2x/15 - 4/5 - 7

⇒ y = 2x/15 -39/5

This is the equation in slope intercept form.

Multiplying the equation with 15, we get,

⇒ 15y = 2x-117

⇒ 2x-15y = 117 , which is the simplified form of the equation.

we have two angles one of which is angle of elevation and another angle depression.

Using trigonometric ratio,

tan ∅ = P / B

tan 32° = h / 425

0.624= h /425

h= 265.569 ft

tan 29° = h(bottom of the tower) / 425

h(bottom of the tower) = 425 × tan 29°

h(bottom of the tower)  = 235.581 ft

Hope This Helps!!!

Answer: A

Step-by-step explanation: Step 3 is incorrect as it should be 10/8 (or 5/4 simplified.) When we have 8x = 10, we are looking at what number "x" multiplied by 8 gives 10. Meaning we need to have 8(?) = 10. So, to find out what x is, we just divide by 8 from both sides. Since 8x/8 cancels out and becomes just x, we get x = 10/8 since we are dividing 10 by 8. We get 5/4 simplified or 10/8 unsimplified.
