can someone help find me, giving brainly.

Given:

A figure of a right triangle.

To find:

The value of x.

Solution:

According to the geometric mean attitude theorem, if an altitude is drawn from the right angle vertex to the hypotenuse, then the altitude is the geometric mean of segments of hypotenuse.

Using geometric mean attitude theorem, we get

[tex]\dfrac{3}{x}=\dfrac{x}{5}[/tex]

[tex]3\times 5=x\times x[/tex]

[tex]15=x^2[/tex]

[tex]\pm \sqrt{15}=x[/tex]

But side cannot be negative. So,

[tex]\sqrt{15}=x[/tex]

Therefore, the value of x is [tex]\sqrt{15}[/tex].

Answer:

[tex]x = 24\ degrees[/tex]

Step-by-step explanation:

Given

16 degrees = 10 hours

Required

Determine the change over 16 hours

Let the change be represented with x,

So, we have:

16 degrees = 10 hours

x = 15 hours

Cross Multiply:

[tex]x * 10\ hours = 16\ degrees * 15\ hours[/tex]

[tex]x * 10 = 16\ degrees * 15[/tex]

Divide through by 10

[tex]x = \frac{16\ degrees * 15}{10}[/tex]

[tex]x = 16\ degrees * 1.5[/tex]

[tex]x = 24\ degrees[/tex]

Answer:

[tex]\boxed {\boxed {\sf No}}[/tex]

Step-by-step explanation:

If a triangle is a right triangle, it can satisfy Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

where a and b are the legs and c is the hypotenuse.

12 and 84 are the legs because are they shortest. 85 is the hypotenuse because it is the longest side.

[tex]a= 12 \\b=84 \\c=85[/tex]

Substitute the values into the formula.

[tex](12)^2+(84)^2=(85)^2[/tex]

Solve the exponents.

[tex]144+7056=7225[/tex]

Add on the right side.

[tex]7200\neq 7225[/tex]

7220 is not equal to 7225, so these sides cannot be a right triangle.

Answer:

k = 0.381cm/gallon

Step-by-step explanation:

Let the amount a tree grows in one month be x

Let amount of water it is given be y

If the amount a tree grows in one month is directly proportional to the amount of water it is given, then;

x ∝ y

x = ky

k is the constant of proportionality

k = x/y

Given

x = 8cm

y = 21 gallons

k = 8/21

k = 0.381cm/gallon

Answer:

[tex]f^{-1}(x) = \frac{x+8}{8}[/tex]

Domain of f(x): All real values.

Range of f(x): All real values.

Domain of f -1(x): All real values.

Range of f -1(x): All real values

Step-by-step explanation:

We are given the following function:

[tex]f(x) = 8x + 8[/tex]

Since it is a line, we have that both the domain is the range is the real set.

Inverse function:

The domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function.

Finding the inverse function:

Exchange x and y in the original function, and isolate y. So

Original

[tex]y = 8x + 8[/tex]

Exchanging:

[tex]x = 8y - 8[/tex]

Isolating y:

[tex]8y = x + 8[/tex]

[tex]y = \frac{x+8}{8}[/tex]

[tex]f^{-1}(x) = \frac{x+8}{8}[/tex]

Answer:

900 large boxes were sold, and 750 small boxes.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of large boxes of cookies sold.

y is the number of small boxes of cookies sold.

A total of 1,650 boxes of Girl Scout cookies were sold last week.

This means that

[tex]x + y = 1650[/tex]

So

[tex]x = 1650 - y[/tex]

Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group earned $4,650.

This means that

[tex]3.5x + 2y = 4650[/tex]

Since [tex]x = 1650 - y[/tex]

[tex]3.5(1650 - y) + 2y = 4650[/tex]

[tex]5775 - 3.5y + 2y = 4650[/tex]

[tex]1.5y = 1125[/tex]

[tex]y = \frac{1125}{1.5}[/tex]

[tex]y = 750[/tex]

[tex]x = 1650 - y = 1650 - 750 = 900[/tex]

900 large boxes were sold, and 750 small boxes.

Step-by-step explanation:

The probability that the first ball drawn is red and the second ball drawn is blue is 3/20.

The probability that the first ball drawn is red and the second ball drawn is blue, we need to multiply the probability of drawing a red ball on the first draw by the probability of drawing a blue ball on the second draw.

Given that there are 10 balls in total, with 5 red balls and 3 blue balls, the probability of drawing a red ball on the first draw is 5/10 = 1/2.

Since the ball is replaced after the first draw, the total number of balls remains the same for the second draw.

The probability of drawing a blue ball on the second draw is also 3/10.

To find the probability of both events occurring (the first ball being red and the second ball being blue), we multiply the probabilities:

Probability = (Probability of drawing a red ball) × (Probability of drawing a blue ball)

= (1/2) × (3/10)

= 3/20

Answer:

14.3

Step-by-step explanation:

What you would do is add all 6 numbers together. After finding the sum, divide by 6. The 6 represents the amount of numbers in the data set. So you would find 86/6 and get 14.3333. That would be rounded to 14.3. Hope this helped!

Answer:

Step-by-step explanation:

Original area of the rectangle = length × width

= 62 × 48

= 2,976 m²

Diane area of the rectangle = length × width

= 60 × 45

= 2700 m²

Percent error = (original - estimated)/original × 100

= (2976 - 2700)/2976 × 100

= 276/2,976 × 100

= 0.0927419354838 × 100

= 9.2741935483870%

Approximately to the nearest whole percent = 9%

Answer:

pam has x = 7 pennies

sam has 2x + 1 = 14 + 1 = 15 pennies

Step-by-step explanation:

let's take the number of pennies that pam owns be x

sam's pennies = 2× ( pam's pennies ) + 1

=》2x + 1

if the total pennies owned by both = 22

then,

x + 2x +1 = 22

3x = 22 - 1

x = 21 ÷ 3

x = 7

so, pam has x = 7 pennies

sam has 2x + 1 = 14 + 1 = 15 pennies
