180 = 90 + 90 (F)

you must have 3 angles

Answer:

One.

Step-by-step explanation:

A triangle can only have one right angle because all three angles of a triangle MUST add up to be 180 degrees. That means if there are two right angles then the answer would automatically be over 180.

Example:

    90+90+1=181

Therefore, a triangle can only have one right angle

Final answer:

To determine the room's width in a scale model, use the scale conversion ratio of 1 in = 6 ft. The width in the model is calculated to be 2 inches.

Explanation:

A room is 12 feet wide. A scale model of the room has a scale of 1 in = 6 ft,

To find the width of the room in the model, we use the scale conversion ratio: 1 inch on the model represents 6 feet in reality. Since the room is 12 feet wide, the width in the model would be 2 inches (12 feet ÷ 6 feet per inch = 2 inches).

The formula for slope is [tex]\frac{rise}{run} = \frac{y2-y1}{x2-x1}[/tex].

Subtract y1 from y2. (y1= -1, y2 = 3)

3 - -1 = 4

Now subtract x1 from x2. (x1 = 4, x2 = -4)

-4 -4 = -8

Divide the difference between the y coordinates by the difference between the x coordinates.

[tex]\frac{4}{-8}[/tex] or 4 ÷ -8 = -0.5

The slope between the two points is -0.5.

Step-by-step explanation:

The area of the circular base is 707 square feet, calculated using the formula A = πr², where π is 3.14 and the radius is 15 feet.

The question asks for the area of a circular base of a statue with a given radius. This is a question of geometry, and the formula for the area of a circle is A = πr², where A represents the area and r represents the radius. In this case, the radius given is 15 feet.

To calculate the area, we insert the value of the radius into the formula, so it becomes A = π(15)². Since we are asked to use 3.14 for π, the calculation becomes: A = 3.14 * 15², which equals 706.5 square feet.

However, since we have been asked to round to the nearest whole number, the final answer would be 707 square feet.

To find the area of the circular base of the statue, we can use the formula A = πr^2, where A is the area and r is the radius. In this case, the radius is given as 15 feet. Plugging this value into the formula, we get:

A = 3.14 * 15^2 = 3.14 * 225 = 706.5 square feet

Rounding to the nearest whole number, the area of the base is approximately 707 square feet.

Answer:

-7x + 14 = 56

Subtract 14 both sides

-7x + 14 - 14 = 56 - 14

-7x = 42

Divide both sides by -7

(-7x)/(-7) = 42/(-7)

x = -6

To solve for x, you need to isolate/get the variable "x" by itself in the equation:

-7x + 14 = 56     Subtract 14 on both sides

-7x = 42    Divide -7 on both sides to get "x" by itself

x = -6

2x + 18 = 4x - 14

2x = 32

x = 16

y = 180 - (4x - 14) = 180 - (64 - 14) = 130

Using the congruency of the top-right angles, it is found that the value of y is of 130.

The equation y = 2x + 2 is a function, because each 'x' value corresponds to a single 'y' value, as per the mathematical definition of a function.

The graph of the equation y = 2x + 2 does indeed represent a function. In mathematics, a function is defined as a relation in which each input (or 'x' value) corresponds to exactly one output (or 'y' value). In the given coordinate pairs, you will notice that each individual 'x' value (such as -1, 0, 1, and 2) corresponds to a single 'y' value. Furthermore, the equation itself, y = 2x + 2, will always yield a single 'y' value for each 'x' value you substitute into it. This aligns with the definition of a function. Hence, the equation y = 2x + 2 is a function.

Step-by-step explanation:

Maya should first isolate the variable  [tex]\( x^2 \)[/tex] before completing the square.

The steps to solve the quadratic equation [tex]\( 4x^2 + 16x + 3 = 0 \)[/tex] by completing the square are as follows:

1.*Isolate the variable - To do this, Maya should move the constant term to the other side of the equation by subtracting 3 from both sides:

[tex]\[ 4x^2 + 16x = -3 \][/tex]

2. Factor out the coefficient of  -The coefficient of x² is 4. Factor out 4 from the terms involving  x

[tex]\[ 4(x^2 + 4x) = -3 \][/tex]

3. Complete the square To complete the square, Maya should add the square of half the coefficient of x t both sides of the equation. Half of 4 is 2, and [tex]\( (2)^2 = 4 \),[/tex]so she should add 4 to both sides:

 [tex]\[ 4(x + 2)^2 = 1 \][/tex]

After completing these steps, Maya can proceed to solve the equation by isolating x and taking the square root.

Answer:

The lines representing these equations intercept at the point (-4,2) on the plane.

Step-by-step explanation:

When we want to find were both lines intercept, we are trying to find a pair of values (x,y) that belongs to both equations, which means that it satisfies both equations at the same time.

Therefore, we can use the second equation that gives us the value of y in terms of x, to substitute for y in the first equation. Then we end up with an equation with a unique unknown, for which we can solve:

[tex]x+y=-2\\x+(2x+10)=-2\\x+2x+10=-2\\3x+10=-2\\3x=-2-10\\3x=-12\\x=\frac{-12}{3} \\x=-4[/tex]

Next we use this value we obtained for x (-4) in the same equation we use for substitution in order to find which y value corresponds to this:

[tex]y=2x+10\\y=2(-4)+10\\y=-8+10\\y=2[/tex]

Then we have the pair (x,y) that satisfies both equations (-4,2), which is therefore the point on the plane where both lines intercept.

Answer:

Step-by-step explanation:

Given

f(x) = x² - 8x - 4

The leading term in the expression is x²

with a coefficient of 1 ← leading coefficient

The leading coefficient of a quadratic function of equation  fx=x2-8x-4 is 1.

The leading coefficient of a quadratic function is the coefficient of the x² term. In the quadratic function f(x) = x² - 8x - 4, the leading coefficient is 1 because the coefficient of x² is always assumed to be 1 when not explicitly shown.

Answer:

The length of the longer segment of the 50 cm chord = 40

Step-by-step explanation:

let the length of the longer segment of the 50 cm chord = x

so, the other segment = 50 - x

A chord of 50 cm bisects a chord of 40 cm

using the Intersecting Chords Theorem

so, x(50-x) = 20 * 20

50x - x² = 400

x² - 50x + 400 = 0

(x - 40)(x - 10) = 0

x = 40 or x = 10

So, the the length of the longer segment of the 50 cm chord = 40

Answer:

The sprinkler can spread water in a radius of 24 feet.

Step-by-step explanation:

Since the sprinkler sends water in a circular pattern in order to find the distance at which it can spread the water we need to find the radius of the circle. The area of the circle is said to be 1808.64 and it's formula is given by:

area = pi*r²

1808.64 = 3.14*r²

r² = 1808.64/3.14 = 576

r = sqrt(576) = 24 feet

The sprinkler can spread water in a radius of 24 feet.

Answer:the way you put this answer is not readable sorry.

Step-by-step explanation:

The statement is false; the formula to determine "And" probabilities varies depending on whether events are independent or dependent.

The statement "And" probabilities can always be determined using the formula P(A and B) = P(A) - P(B) is false. The correct method to determine the probability of two events A and B occurring together, also known as the conjunction, depends on whether the events are independent or dependent. If A and B are independent, the formula is P(A and B) = P(A) × P(B). However, if A and B are dependent, you must use the formula P(A and B) = P(A) × P(B|A), where P(B|A) represents the conditional probability of B given that A has already occurred.

Step-by-step explanation:

First you multiply 52 by $7.75

This gives you $403

Then you subtract 52 from 100 to find the remainder of shirts

This gives you 48

So then you multiply 48 by $9.25

This gives you $444

Then you add $444 and $403 giving you $847.00

Answer:

The answer is B: 847

Step-by-step explanation:

52 x 7.75 = 403

100 - 52 = 48

48 x 9.25 = 444

444 + 403 = 847
