Then you round down since only 89 full boxes can be made.
What is the probability of landing on red and rolling a number greater than 2?
Using it's concept, considering a spinner with four sections and a die with 6 numbers, there is a [tex]\frac{1}{6}[/tex] probability of landing on red and rolling a number greater than 2.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
The spinner has 4 sections, one of which is red, hence P(A) = 1/4.The die has 6 numbers, four of which are greater than two, hence P(B) = 4/6.The events are independent, hence:
[tex]P(A \cap B) = P(A)P(B) = \frac{1}{4} \times \frac{4}{6} = \frac{1}{6}[/tex]
[tex]\frac{1}{6}[/tex] probability of landing on red and rolling a number greater than 2.

Classify the angles in the figure by choosing the correct term from the choices below.
supplementary
complementary
vertical
none of these
Answer: none of these
Step-by-step explanation:
They are not supplementary because 101+77 = 178 and not 180.
They are not complementary because 101+77 = 178 and not 90.
They are not vertical because there are no intersecting lines and the two angle measures are not equal.
Therefore, none of these are true.
The vertices of quadrilateral WXYZ are W(-5,5), X(-3, 8), Y(6, 2), and Z(4, -1). What choice is the best description of quadrilateral?
A. Trapezoid
B. Square
C. rhombous, that is not square
D. rectangle, that is not square
Please provide explanation. DOn't just say one option.
Quadrilaterals are shapes with four sides
The description of the quadrilateral is (d) rectangle, that is not square
How to determine the shapeThe coordinates are given as:
W(-5,5), X(-3, 8), Y(6, 2), and Z(4, -1)
Next, we plot the coordinates on a graph (see attachment)
From the attachment, we can see that the coordinates form a rectangle

What is the value of x
Answer:
X=55
Step-by-step explanation:
It says 15, so what you want to do is times 15x14 because those are the only sides of the shape. After you multiply 15x14 which is 60, you need to minus 5 because it shows a subtraction sign. So, 60-5= 55. X=55
The equation for line p can be written as y= – 5/4 x–6. Line q includes the point (5, – 8) and is parallel to line p. What is the equation of line q?
Answer:
y = -(5/4)x - (1 3/4)
Step-by-step explanation:
A line parallel to y= -(5/4)x - 6 will have the same slope, -(5/4), but a different value for the y-intercept, which is -6 in this equation. This means we can write:
y = -(5/4)x + b
As klong a b is not -6, the line will be parallel. But we are told that point (5,-8) must be on the new line. That means we need to select a value of b to make that happen. By shifting b, we can move the straight line up or down. To move it so that it goes through (5,8), enter that point in the equation and solve for b:
y = -(5/4)x + b
-8 = -(5/4)*5 + b for (5,-8)
-8 = -(25/4) + b
b = -8 + (25/4)
b = -(32/4)+(25/4)
b = -(7/4) or - 1 3/4
The parallel line that goes through (5,-8) is y = -(5/4)x - 2
Answer:
y=-5/4x-7/4

What is the slope of a line that passes through the points (5,-3) and (13, -9)
Step-by-step explanation:
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.
so, we see
x changes by +8 (from 5 to 13).
y changes by -6 (from -3 to -9).
so, the slope is -6/+8 = -3/4
Hello.
Let's find the slope using the slope formula:
[tex]\mathrm{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]
[tex]\mathrm{\displaystyle\frac{-9-(-3)}{13-5} }[/tex]
[tex]\mathrm{\displaystyle\frac{-9+3}{13-5} }[/tex]
[tex]\mathrm{\displaystyle\frac{-6}{8} }[/tex]
The fraction can be simplified:
[tex]\mathrm{\displaystyle-\frac{3}{4} }[/tex]
Therefore, the slope is
[tex]\mathrm{\displaystyle-\frac{3}{4} }[/tex]

A garden measuring 15 meters by 20 meters is to have a pedestrian pathway installed
all around it, increasing the area to 336 square meters.
a. Write an expression to represent the area of the total garden including the
pathway.
b. What will be the width of the pathway?
The area of the garden is the amount of space on the garden.
The area of the total garden is (x + 15)(x + 20)The width of the pathway is 1 meterThe expression of the areaThe dimensions of the garden is given as:
15 meters by 20 meters
Let the width of the pedestrian pathway be x.
So, the area of the total garden is:
[tex]Area=(x + 15)(x + 20)[/tex]
The width of the pathwayIn (a), we have:
[tex]Area=(x + 15)(x + 20)[/tex]
The total area is given as: 336.
So, we have:
[tex](x + 15)(x + 20) = 336[/tex]
Expand
[tex]x^2 + 35x + 300 = 336[/tex]
Collect like terms
[tex]x^2 + 35x + 300 - 336 = 0[/tex]
Evaluate
[tex]x^2 + 35x - 36 = 0[/tex]
Expand
[tex]x^2 + 36x -x - 36 = 0[/tex]
Factorize
[tex]x(x + 36) -1(x +36) = 0[/tex]
Factor out x + 36
[tex](x + 36)(x -1) = 0[/tex]
Solve for x
x = -36 or x =1
The width cannot be negative.
Hence, the width of the pathway is 1 meter

Find angle measure x on each given figure. (Lessons 9.2, 9.4, 9.5)
1. x = 60 (in this trapezoid, opposite angles are equal)
2. Find the third angle of the left triangle : 180 - 17 - 133 = 30
In a parallelogram, the side that is opposite to a side is parallel to each other.
x and the 30 degree are alternate angles -> x = 30
3. (I'll call the 4 triangles A,B,C,D respectively in anticlockwise)
Triangle A has the 25 degree angle, and the bottom right angle of triangle C, they are alternate angles (and the sides are parallel due to the property.)
So, the bottom right angle of triangle C = 25
Triangle C and D form an isoceles triangle, so x = 25.
4. This one I'll just do short. There's a right angle in the triangle that contains x.
3 angles in a triangle add up to 180, so x = 180 - 90 - 50 = 40.
