(x + 10) + (x + 10) = 90
90 - (10 + 10) = 70
70/2 = 35
x = 35
Have a great day!
Answer:
x = 35
Step-by-step explanation:
Since we know that this is a right angle, we know that the total has to equal 90 degrees. From there, we can make an equation:
(x+10) + ( x+10) = 90
2x +20 = 90
2x = 70
x = 35

A) 1/24 B) 1/6 C) ½ D) 1/12
Answer:
D
Step-by-step explanation:
Given:
Lou has the first 4 encyclopedias lined up on a shelf, A, B, C, and D.
To find: probability that he picks A first and B second if he picks two at random
Solution:
Total number of outcomes = [tex]4!=4(3)(2)(1)=24[/tex]
Favourable outcomes are ABCD, ABDC
Number of favourable outcomes = 2
probability that he picks A first and B second = Number of favourable outcomes / Total number of outcomes = [tex]\frac{2}{24}=\frac{1}{12}[/tex]

Answer:
Numbers greater than or equal to 15950 and less than 16050.
Step-by-step explanation:
Given:
The town Diego lives in has a population of about 16,000
To fill: the blanks
Solution:
Numbers 15950, 15951, 15952, 15953,...., 16000, 16001, 16002,..., 16049 are rounded off to 16,000 when rounded to the nearest hundred.
In other language, numbers greater than or equal to 15950 and less than 16050
Numbers greater than or equal to 15950 and numbers less than or equal to 16049 will round round to 16000 when rounded to the nearest hundred.
To round to the nearest hundred :
When the value of the tens digit is greater than or equal to 5, it is rounded up to 1 and added to the hundred digit If the tens digit is less than 5, it is rounded to 0.15950, tens digit is 5, when rounded to 1 and added to the hundred digit, we have 16,00016049 ; tens digit is 4, it is rounded to 0 a d we have 16000Therefore, Values below 15950 and beyond 16049 will not round to 16000(to the nearest hundred).

By applying the Pythagorean theorem to both triangles and connecting them, we find that x is roughly 11.547 cm, establishing the relationship between the side lengths in these right triangles.
Let's explore the relationship between two right triangles, ABC and ACF, and calculate the value of x using the Pythagorean theorem.
Triangle ABC is a right triangle with sides BC and AB both measuring x cm. By applying the Pythagorean theorem (a^2 + b^2 = c^2), where c is the hypotenuse, in this case, AC, we find:
AC² = x² + x² = 2x²
This equation relates the lengths of the sides of triangle ABC.
Now, consider triangle ACF. It's also a right triangle with side CF measuring x cm and a hypotenuse AC, which is 20 cm long. Applying the Pythagorean theorem again:
20² = AC² + x²
Since we already established that AC² is 2x² from the first triangle, we can substitute it in:
20² = 2x² + x²
This equation connects the two triangles. To find the value of x, we need to solve this equation:
20² = 3x²
Now, isolate x:
x² = (20²) / 3
x² = 400/3
x = √(400/3)
x ≈ 11.547 cm
So, x is approximately 11.547 cm.

PLEASE HELP ME!! f(x) = -4x2 + 10x – 8
What is the value of the discriminant of f?
How many distinct real number zeros does f have?
The discriminant of the quadratic function f(x) = -4x^2 + 10x - 8 is -28. Since the discriminant is negative, there are no distinct real number zeros for this function.
Your question involves finding the discriminant of the quadratic function f(x) = -4x2 + 10x - 8 and determining how many distinct real number zeros it has. The discriminant of a quadratic equation in the form ax2 + bx + c is given by b2 - 4ac. In your case, a = -4, b = 10, and c = -8. Let's calculate the discriminant:
b2 - 4ac = (10)2 - 4(-4)(-8)
b2 - 4ac = 100 - 128
b2 - 4ac = -28
Since the discriminant is negative (b2 - 4ac < 0), the quadratic function f(x) has no real number of zeros. Therefore, the graph of the function does not cross the x-axis, and there are no distinct real roots.
In the figure below, find the exact value of y. (Do not approximate your answer.)

The Pyramid of Khafre in Egypt stands 471 feet tall. The sides of its square base are 705 feet in length. Find the lateral surface area of the Pyramid of Khafre. (Hint: Use the Pythagorean Theorem to find the pyramid’s slant height)
Answer:
Lateral surface area = 4 (1/2 × 705 × 588.30) = 829503 ft²
Step-by-step explanation:
The pyramid is a square base pyramid. The height = 471 ft. The sides of the square base pyramid = 705 ft.
To calculate the lateral area of the square base pyramid we have to know the slant height. The slant height can be known by using Pythagoras theorem to solve for it.
c² = a² + b²(Pythagoras theorem)
base = b = 705/2 = 352.50 ft
c² = 352.50² + 471²
c² = 124256.25 + 221841
c² = 346097.25
square root both sides
c = √346097.25
c = 588.300305966
c ≈ 588.30 ft
slant height = 588.30 ft
Lateral surface area = sum of area of the 4 triangular faces
lateral surface area = 4 (1/2 × base × height)
Lateral surface area = 4 (1/2 ×705 × 588.30) = 829503 ft²

Graph a line that contains the point ( 3 , -6) and has a slope of 1/2
1/2x - 7.5Step-by-step explanation:The image below shows proof that the equation y = 1/2x - 7.5
Step-by-step explanation:
The equation of the line contains the point ( 3 , -6) graph is shown below.
Since the point (3, -6) lies on the line, we can use the point-slope form of linear equations to find the equation of the line, which is:
[tex]y - y_1 = m(x - x_1)[/tex]
where [tex](x_1, y_1)[/tex] is the point on the line and m is the slope of the line.
Substituting in (3, -6) and m = 1/2, we get:
y - (-6) = 1/2(x - 3)
y + 6 = 1/2x - 3/2
y = 1/2x - 3/2 - 6
y = 1/2x - 9/2
To graph the line, we can start by plotting the point (3, -6). Then, we can use the slope to find another point on the line.
Since the slope is 1/2, it means that for every 1 unit we move up, we must also move 2 units to the right.
Therefore, we can move 2 units to the right and 1 unit up from (3, -6) to find the point (5, -5). We can then plot this point and connect the two points with a line.
Here is a graph of the line that contains the point (3, -6) and has a slope of 1/2:
The graph shows that the line passes through the point (3, -6) and has a positive slope.

√625= 25
Answer:

Step-by-step explanation:
1) So "x" is the measurement of the longest side in a right angle triangle. The longest side is called the hypotenuse
there is actually a formula to find the measurement of the hypotenuse called the pythagorean theorem
so
a^2+b^2=c^2
where a=measurement of one side
b=measurement of other
and c=hypotenuse
hence,
24^2+7^2=x^2
576+49=x^2
625=x^2
to find value of x by itself take square root on both sides:

C)√9
D) √169
E) √78
F)π = 3.14...
Answer:
The irrational numbers are;
√18 ; √78 and π = 3.14...
Step-by-step explanation:
An irrational number is a number that cannot be written as the ratio of two integers. Its decimal form does not stop and does not repeat.
Thus;
A) 9/15 = 0.6 It's decimal stops after 6 and thus it is not irrational
B) √18 = 4.242640687119285.... The decimal doesn't repeat and the continuous dots means it's decimal doesn't stop. Thus it is an irrational number
C) √9 = 3. Doesn't have a repeating or continuous decimal and thus it's not irrational
D) √169 = 13. Doesn't have a repeating or continuous decimal and thus it's not irrational
E) √78 = 8.831760866327846......
The decimal doesn't repeat and the continuous dots means it's decimal doesn't stop. Thus it is an irrational number
F) π = 3.14.... The continuous dots means it's decimal doesn't stop. The decimal doesn't repeat and so, it's an irrational function
