Answer:
The total number of planes = 23 planes
Step-by-step explanation:
The number of planes are give as follows;
The number of planes with three points, given that any three points of an octahedron forms a plane are ₆C₃ = 20
The number of distinct planes that has 4 points in the octahedron = 3
Therefore, the total number of planes are 20 + 3 = 23 planes.
h(x)=2x+5 k(x)=x+3 find (h(k(x)))
Answer:
h(k(x)) = 2x + 11
Step-by-step explanation:
Step 1: Define
h(x) = 2x + 5
k(x) = x + 3
h(k(x))
Step 2: Substitute and Evaluate
k(x) = x + 3 = x
h(k(x)) = 2(x + 3) + 5
h(k(x)) = 2x + 6 + 5
h(k(x)) = 2x + 11
Hailey is putting up a fence in the shape of an isosceles triangle in her backyard. The fence has side lengths as shown, where x represents the number of feet in each fence section. The perimeter of the fence can be covered using 8 total fence sections represented by the expression 8x. If fencing costs $6.50 a foot, what would be the total cost of the fence?
Answer: The total cost would be $780.00
The expression for the total cost of fencing is $52x , where x is a variable representing the number of feet in one section.
What is an expression in one variable?An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .
Given that number of feet in one fence section be x
No of feet in 8 such fence section = 8x
Given , Perimeter = 8 fence sections = 8x feet
Cost of fencing of one foot = $6.50
Cost of fencing 8x feet = 8x * 6.50
Therefore , the total cost of the fencing can be given by = 8x*6.50
= $ 52 x
Thus, the expression for the total cost of fencing is $52x

Q. What is the equation by looking at this graph?
Answer:
y=x+2
Step-by-step explanation:
slope is 1
y-int is +2
Answer:
y = 3 + 1/1
Step-by-step explanation:
First, the line passes the y-intercept at 3, so we have y = 3. But we also need the slope. Because the slope is 1/1 or 2/2, the equation would be this:
y = 3 + 1/1

Which describes the slope of the given line?
A. Zero
B. Unidentified
C. Negative
D. Positive
Answer:
Option C (Negative)
Step-by-step explanation:
A line with a negative slope goes downward from the left side of the graph to the right side.
A positive line would be the opposite; the line goes upward form left to right.
A horizontal line has zero slope. A vertical line has undefined slope.
The given line has the line going downward.
Option C should be the correct answer.
Hope this helps.
Answer:
C. Negative
Step-by-step explanation:
the line moves from left to right(it's going down) meaning it has a negative slope.

Plot the image of point Q under the translation (x, y) + (x - 3, y + 4).
Answer:
( 2, -1 )
Step-by-step explanation:
The image of the assumed point Q(2, 3)) under the translation is Q'(-1, 7).
What is Translation?Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.
Translation of a point (x, y) indicates that the point is moved x units along the X axis and y units along the Y axis,
Here we have to translate the point Q(2, 3).
Point (x, y) is translated as (x - 3, y + 4).
That is the point (x, y) moves 3 units to the left along the X axis and 4 units upwards along the Y axis.
Q(2, 3) after the translation becomes,
Q'(2 - 3, 3 + 4) = Q'(-1, 7)
Hence the point Q(2, 3) under the translation (x - 3, y + 4) is the point Q'(-1, 7).

What was the percentage increase to one decimal place?
NO SILLY ANSWERS OR REPORT!
Answer:
13%
Step-by-step explanation:
The percentage decrease is calculated by the formula below;
( new value - old value)old value * 100%
old value is 130
new value is 115
So the percentage increase will be;
(130-115)/115 * 100%
= 15/115 * 100% = 13.043%
To one decimal place, this is 13%

There are 10 marbles in a bag 1/5 are red and the others are blue. What is the ratio of red to blue marbles?
Answer:
1:4 ratio
Step-by-step explanation:
The Answer is a 1:4 ratio because 1/5 of 10 is 2 and 4/5 of 10 is 8 so the ratio would look like 2:8. You would then simplify 2:8 to 1:4.
Ratio of red to blue marbles is 1:5
An equation is used to show the relationship between two or more numbers and variables.
10 marbles in a bag 1/5 are red and the others are blue.
number of red marbles = 1/5 * 10 = 2
number of blue marbles = 10 - 2 = 8
Ratio of red to blue marbles is 2:8 = 1:5
