A square has sides of length 15. What is the length of the diagonal?
А
14/4
B
15/2
C
16/5
D
12/3
Answers
Answer:
15 sqrt(2) =c
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
The legs are 15 and the hypotenuse is the diagonal
15^2 + 15^2 = c^2
2 * 15^2 = c^2
Take the square root of each side
sqrt(2 * 15^2 )=sqrt( c^2)
sqrt(2) sqrt(15^2) = c
15 sqrt(2) =c
Answer: 15[tex]\sqrt{2}[/tex] (b)
Step-by-step explanation:
You can separate a square into two different 45-45-90 degree triangles.
Where x = 15, and the diagonal would be the hypotenuse.
So, here you can use the Pythagorean Theorem to find the hypotenuse to use 45-45-90 triangle theorem where they hypotenuse is always x times [tex]\sqrt{2}[/tex]
So, the diagonal would be 15[tex]\sqrt{2}[/tex]

a bag is filled with 4 red marbles, 3 blue marbles,3 yellow marbles, and 2 green marbles. you randomly choose one marble from the bag. (a) find the number of ways the event can occur. (b) find the favorable outcomes of the event
Answers
Answer:
a. 12
b. it depends on the color of the marble.
Step-by-step explanation:
In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:
4 + 3 + 3 + 2 = 12
Therefore, the number of ways the event can occur is 12 ways.
Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.
In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.

what is the volume of the cylinder
Answers
Answer:
Step-by-step explanation:
volume =πr²h=π×4²×8=128π in³
Finding the volume of a cylinder involves its formula: b*h=v. In the case of a cylinder and even cones, your base is a circle, and therefore is the area of said circle.
What you first want to do is find the area of the circle, to do that you need to know the formula which is r^2*pi. A cylinder has two congruent sides which are the circles, therefore the radius of one circle is the same as the other. Now use the radius of the circle on the top of the cylinder and square it. 4^2=16. Next we need to multiply 16 by pi (pi can be multiplied like a variable and just added next to 16. Therefore 16*pi= 16π.
Next now that you have your base (16π) you must multiply by your height which is 8 in this case (the length between the two circles). 16π*8 and now multiply as it it were two terms (a variable and whole number) so 16π*8= 128π
Name a game or sport in which parallel lines are important in game play and/or scoring
Answers
Answer: FOOTBALL
Step-by-step explanation:
Angles play a crucial role in football, from a pass or kick, to the way players move and how plays are called. Football players can even use angles to enhance their individual or team performance. For example, a football placekicker must know what angle to kick the ball at to score a field goal. The path the football will take once it’s kicked comes down to the angle at which it is kicked, the amount of force applied, and the height of the kick. When kicking from thirty yards away, a larger angle is necessary to get the ball through the goalpost. However, when making a fifty yard kick, a shorter angle is called for, so the ball can travel the greater distance to the goal. When the opposing team is trying to block the kick, a higher angled kick is necessary.

Answers
Answer:
a) Any 2 sides
b) exactly 90°
Step-by-step explanation:
The point of the Pythagorean Theorem is to find the length of the hypotenuse using 2 sides.
This only works for right triangles.

-MoCKEry
Answer:
1) any two sides
2)exactly 90 degrees
Step-by-step explanation:
1) The pythagorean theorem only applies to right angle triangles
since right angle triangles measure 90 degrees exactly we will choose exactly 90 as an option.
2) so the formula for pythagorean theorem is a^2+b^2=c^2 where
a=side 1
b= side 2
c=hypotenuse(biggest side)
to find the hypotenuse you need to know both the values of a and b hence we will take the option "any two sides"
Find the mean absolute deviation (MAD) of the data in the pictograph
Answers
Answer:
1.5
Step-by-step explanation:
First, find the mean (average) of the data set.
mean = (x1 + x2 + ...)/N
where x1, x2, ... are the data points, and N the total amount of data points.
mean = (7 + 2 + 4 + 3)/4 = 4
Then, mean absolute deviation is computed as follows:
MAD = (|x1 - mean| + |x2 - mean| + ...)/N
MAD = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|)/4
MAD = (3 + 2 + 1)/4 = 1.5

a. x = 6
b. x = 6.4
c. x = 27
d. x = 160
Answers
Answer
x = 32/5 = 6.400
Answer is B
Step-by-step explanation:
1: Rearrange
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
Solving a Single Variable Equation
Solve : 5x-32 = 0
Add 32 to both sides of the equation :
5x = 32
Divide both sides of the equation by 5:
x = 32/5 = 6.400
The correct answer is B.
Answer: x = 32/5 = 6.400
Hope this helps.
Answer:
B
Step-by-step explanation:
5x=32 move the 5 over by dividing
x=5/32. 5 divided by 32 equals 6.4
so x=6.4

Answer:
402 cm.
Step-by-step explanation:
To find this, we will need to calculate the circumference of the reel. We can do this using the formula [tex]C = d\pi[/tex].
Since the radius is 4 cm, the diameter is 8 cm. Put this into the equation to solve for the circumference:
[tex]C = 8\pi = 25.12[/tex]
Since the reel spun 16 times, simply multiply the circumference by 16 to get:
25.12 × 16 = 401.92
≈ 402 cm.

A point is selected at random inside the given figure. What is the probability the point will be in the region labeled B? Enter your answer, as a fraction in simplest form, in the box. The figure is a rectangle that is made up of three rectangles and one square. The rectangles are labeled A, B, and D, and the square is labeled C. Rectangle A is in the upper left portion of the large rectangle. The left side of rectangle A is labeled 5 inches and it is part of the left side of the large rectangle. Rectangle B is in the lower left portion of the large rectangle below rectangle A. The lower side of rectangle B is labeled 3 inches and makes up a part of the lower side of the large rectangle. Rectangle D makes up the right side of the large rectangle and is to the right of rectangle A. The upper side of rectangle D is labeled 3 inches and makes up a part of the upper side of the large rectangle. The right side of rectangle D makes up the entire right side of the large rectangle. Square C lies below rectangle A and between rectangles B and D. The lower side of square C is labeled 4 inches and makes up part of the lower side of the big rectangle. The right side of square C is also labeled 4 inches.
Answers
Answer:. 12/90. Or about 13.3%
Step-by-step explanation: If I interpreted your description correctly, and put the dimensions in the correct places, the large rectangle has an overall width of 10 inches and length of 9 inches. The Total Area is 90 sq in.
The rectangle Region B is 3 (given) by 4 (assumed from shared side with the given square) . So the Area of region B is 12 sq in.
The chance of randomly selecting a point is the ratio of the Area of the selected region to the Total Area. In this example, it's 12/90, simplified to 2/15 or about 13.3%

length = 4 ∛24 ft width = 6 ∛3 ftThe area of the rectangular region is computed as follows:
area = length * width
area = 4 ∛24 * 6 ∛3
area = 4*6* ∛(24*3)
area = 24 * ∛(2³*3*3)
