Which best describes the statement a plane contains at least 3 points not on the same line?
a. always true
b. sometimes true
c. never true
d. cannot tell
Answer: a. always true
Step-by-step explanation:
A plane is defined as a line and a point outside this line.
We know that for any set of two points, we can draw a line throug them.
Then if we have "3 points not in the same line" is equivalent to have two points in the same line, and the third point outside of it, then this is the definition of a plane.
Then the correct option is A, always true.

Answer:
$6.03
Step-by-step explanation:
cost of oranges per pound: .99
banaenaes: 1.39
you need to find the total cost for prestons bananas plus his oranges
oranges: .99 x 2.3 = 2.277
bananas: 1.39 x 2.7 = 3.753
2.277+3.753= $6.03

55) A dilation of scale factor of 4 will produce a congruent figure
True or False
Answer:
False
Step-by-step explanation:
When a figure is dilated by a scale factor of 4, the new figure produced will be 4 times the size of the original figure. This means that, the size would change while the shape remains the same as the original figure.
Congruent figures must have the same shape and size.
Therefore, the figure produced when a dilation of scale factor of 4 is done is not a congruent figure. Rather, it is a similar figure.
So, get statement is FALSE.

Answer:1.00
Step-by-step explanation:
A=74-72/2.0
And I did it on kahn
The z - score for the Stephanie’s exam grade will be 1.
What is Standard deviation?
Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given that;
The grades on a physics midterm at Covington are roughly symmetric with μ = 72 and σ = 2.0.
And, Stephanie scored 74 on the exam.
Now,
The formula for the z - score = ( X - μ ) / σ
Substitute all the values, we get;
The z - score for the Stephanie’s exam grade = ( 74 - 72 ) / 2.0
= 2 / 2
= 1
Thus, The z - score for the Stephanie’s exam grade will be 1.

Answer:
➨ f(-1) = 0
Step-by-step explanation:
➨ Look at the table and compare.
Notice that when x = -1, f(x) = 0
f(-1) is like substituting x = -1 and get the f(x) value at x = -1.
Thus, f(-1) = 0
Brian and Colin win some money and share it in the ratio 5:1. Brian gets £60 more than Colin. How much did they get altogether?
Brian gets 5x and Colin gets x amount.
Brian gets 60 more than Colin, so you get:
5x - x = 60
Simplify to get:
4x = 60
Divide both sides by 4:
x = 15
Brian gets 5x = 5(15) = 75
Colin gets x = 15
75 + 15 = 90
The total amount they get is £90

Step-by-step explanation:
The required value of XQ is 9 units if MQ= 3x-3 and XQ= 2x-6.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment MQ, where the length of line segment XQ refers to the distance between its endpoints, M and Q.
Given that X is the midpoint of MQ
MQ= 3x-3 and XQ = 2x-6
M______________X______________Q
Since M is the midpoint of XQ, So XQ = 2MQ
⇒ MQ = 2XQ
Substitute the values of MQ= 3x-3 and XQ= 2x-6,
⇒ 3x -3 = 2(2x-6)
⇒ 3x -3 = 4x - 12
⇒ 4x - 3x = 12 - 3
⇒ x = 9
Substitute the values of x = 9 in XQ = 2x-6
So XQ = 2(9) - 6 = 18 - 6 = 12
Hence, the required value of XQ is 9 units

Lewis directs the school marching band. He uses scale drawings of the football field to design marching formations for the band. The football field is 100 yards long and 53 1/3 yards wide. Lewis always uses a scale of 1 inch to 10 yards for his drawings.
Complete the steps below to find the length and width of the football field as it appears in one of Lewis’s scale drawings.
Part A
What is the actual area of the football field? Assume that the field is shaped like a rectangle.
Part B
Write a ratio to represent the scale used in the drawing.
Part C
What is the length of the football field in the scale drawing?
Part D
What is the width of the football field in the scale drawing?
Part E
What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.
Part F
What is the ratio of the area of the football field in the scale drawing to the area of the actual football field?
Part A: 5,333[tex]\frac{1}{3}[/tex] square yards
EX: The length of the football field is 100 yards. The width of the field is 53[tex]\frac{1}{3}[/tex] yards.
Part B: 1/10 inch per yard
EX: The scale used in the drawing is 1 inch to 10 yards. I can represent this ratio in several different ways: 1 inch to 10 yards, 1 inch : 10 yards, 1 in/ 10 yd or 1/10
Part C: 10 inches
EX: Set up a proportion where the numerators are the measurements in the scale drawing and the denominators are the actual measurements of the football field:
1 in. / 10 yd. = × in. / 100 yd.
Cross multiply, and then divide both sides by 10 to solve for x:
100 = 10x
10 = x
Part D: 5 1/3
EX: Use the actual width of 53[tex]\frac{1}{3}[/tex] yards and the scale to find the width of the field in the scale drawing.
Set up a proportion where the numerators are the measurements in the scale drawing and the denominators are the actual measurements of the football field:
1 in / 10 yd = 53[tex]\frac{1}{3}[/tex] yd
Cross multiply, and then divide both sides by 10 to solve for x:
10x = 53[tex]\frac{1}{3}[/tex]
x = 160/3 ÷ 10
x = 16/3
x = 5[tex]\frac{1}{3}[/tex]
Part E: 53 1/3
EX: In the scale drawing, the length of the football field is 10 inches and the width is 5[tex]\frac{1}{3}[/tex] inches. The area of a rectangle is length × width:
area = length × width
= 10 in. x 5[tex]\frac{1}{3}[/tex] in.
= 53[tex]\frac{1}{3}[/tex] sq. in. ( square inches)
Part F: The ratio is 1 square inch to 100 square yards
EX: The area of the football field in the scale drawing is 53[tex]\frac{1}{3}[/tex] square inches.
The area of the actual football field is 5,333[tex]\frac{1}{3}[/tex] square yards.
The calculation for the ratio of the scaled area to the actual area is
53[tex]\frac{1}{3}[/tex] sq. in. / 5,333[tex]\frac{1}{3}[/tex] sq. yd. = 1 sq. in. / 100 sq. yd.

Answer:
f(-2) = 13
g(4) = -9
Explanation:
Whenever a question is asking you to find something like, in this example, f(-2) or g(4), you have to substitute whatever number is in the parentheses for every x in the function with that letter.
Let's try to find f(-2). We have to substitute -2 for every x in the function f and simplify:
[tex]f(-2) = -2 (-2)^{3} -3\\f(-2) = -2(-8)-3\\f(-2) = 16 - 3 \\f(-2) = 13[/tex]
Therefore, [tex]f(-2) = 13[/tex].
Next, let's try to find g(4). We have to substitute 4 for every x in the function g and simplify:
[tex]g (4) = -2(4) - 1\\g(4) = -8-1\\g(4) = -9[/tex]
Therefore, [tex]g (4) = -9.[/tex]

We know angle A=74º, angle B=77º, angle C=70º, angle D=39º, and angle E=36º. What is the measure of angle F in degrees?
Answer:
64º
Step-by-step explanation:
We can find ∠F by looking at triangle BDF. A triangle's interior angles add up to 80º. We know that ∠B=77º and ∠D=39º, and ∠B+∠D+∠F=180º. So, 77º+39º+∠F=180º. Therefore, 116º+∠F=180º, and ∠F=64º.
Based on the information given, the value of angle F is 64°.
From the information given, it was stated that angle A=74º, angle B=77º, angle C=70º, angle D=39º, and angle E=36º.
Therefore, the measure of angle F in degrees will be calculated thus:
B + D + F = 180°
77° + 39° + F = 180°
116° + F = 180°
F = 180° - 116°
F = 64°
