The age of a tree when the diameter is 11 inches is 80.

What is the age of the tree?

The age of the tree increases by 10 with a 1 inch increase in the diameter of the trunk. This represents a linear increase.

The equation that can be used to represent the age of a tree given its diameter is :

age of the tree when the diameter is 4 inches + [(difference between 11 inches and 4 inches) x rate of change in age)

10 + (10 x 7)  = 80

8 more than twice Jenny's age
Use the variable j to represent Jenny's age. Please help.. :(

Answers

Answer:

2j + 8

Step-by-step explanation:

Given:  8 more than twice Jenny's age

Let j = Jenny's age

"twice Jenny's age" means double (multiply by 2) Jenny's age  = 2j

"more than" means to add, so "8 more than" = + 8

Therefore:

"8 more than twice Jenny's age" = 2j + 8

One of the legs of a right triangle is twice as long as the other, and the perimeter of the triangle is 28. Find the length of the hypotenuse.

In a right triangle, the 58-cm hypotenuse makes a 51-degree angle with one of the legs. To the nearesttenth of a cm, how long is that leg?

Evaluate: sin (Arccos(5/13))

Evaluate: tan(Arctan(π/6))

Answers

1) If we let the lengths of the legs be x and 2x, then by the Pythagorean theorem,

[tex]x+2x+\sqrt{x^{2}+(2x)^{2}}=28\\3x+x\sqrt{5}=28\\x(3+\sqrt{5})=28\\x=\frac{28}{3+\sqrt{5}} \cdot \frac{3-\sqrt{5}}{3-\sqrt{5}}=21-7\sqrt{5}[/tex]

This means that the length of the hypotenuse is:

[tex]\sqrt{5}(21-7\sqrt{5})=\boxed{21\sqrt{5}-35}[/tex]

2) (Diagram attached) We know that

[tex]\cos 51^{\circ}=\frac{x}{58}\\x=58 \cos 51^{\circ} \approx \boxed{36.5}[/tex]  (in cm)

3) From the Pythagorean identity,

[tex]\sin^{2}\left (\arccos \frac{5}{13} \right)+\cos^{2} \left (\arccos \frac{5}{13} \right)=1\\\left(\frac{5}{13} \right)^{2}+\sin^{2} \left (\arccos \frac{5}{13} \right)=1\\\frac{25}{169}+\sin^{2} \left (\arccos \frac{5}{13} \right)=1\\\sin^{2} \left (\arccos \frac{5}{13} \right)=\frac{144}{169}\\\sin \left (\arccos \frac{5}{13} \right)=\boxed{\frac{12}{13}}[/tex]

What is Standard normal distribution?

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

For the given problems, the Hypothesis mean is 4.5. The sample mean was 4.75 hours with a normal standard deviation of 2.0.

Now, calculating the z-score,

[tex]z = \dfrac{\bar x - \mu_o}{\dfrac{\sigma}{\sqrt n}}\\\\\\z = \dfrac{4.75-4.5}{\dfrac{2}{\sqrt{15}}}\\\\\\z = 0.48[/tex]

Now, as per the standard normal table, the p-value is 0.6844. Since the p-value is greater than the significance level, the hypothesis can not be concluded.

What is the equation of Parabola ?

The general equation of a parabola is

y = a(x-h)² + k

or

x = a(y-k)² +h

where (h,k) denotes the vertex.

It is given in the question that the value of h is doubled for the equation given

y = a(x-h)² + k

if the value of the h is doubled, the vertex of the graph shifts and shifts on the x axis away from the y axis , therefore

the vertex of the graph moves to a point twice as far from the y-axis.

if a quarter kilogram costs rs 60 then how much will cost for 150 grams

Answers

Answer:

R s. 36

Step-by-step explanation:

1kg ⇒ 1000g

So, a quarter kilogram means,

[tex]\frac{1}{4}[/tex] × 1kg = 1000g ×  [tex]\frac{1}{4}[/tex]

[tex]\frac{1}{4}[/tex] × 1kg = 250g

According to the question,

250g = R s. 60

So, now they're asking for the price of 150g.

Let that price be x.

250g ⇒ R s. 60

150g  ⇒ x

Use cross multiplication to find the value of x.

250x = 60 × 150

250x = 9000

Divide both sides by 250.

x = R s. 36
