Answer:
The answer is A
Step-by-step explanation:
This is one of those sneaky questions where you think there is no definite answer, but don't despair. There is an answer.
You have 7 numbers
3 of them are positive which means greater than 0. Let's pick them
3 4 5 = 60
That part's easy. Those 3 numbers give a plus result.
Now try the other 4 numbers
-3 - 2 - 1 - 4
Do you see what's going to happen. You have -3 * - 2 = 6
then you get - 1 * - 4 = 4
All of a sudden you get a positive result 6 * 4 = 24
60 * 24 = 1440
So the answer is any 3 plus numbers multiplied by 4 minus numbers gives a plus result.
Answer:
a) positive
Step-by-step explanation:
If 3 of the 7 numbers are positive, the other 4 are negative. The product of an even number of negative factors is positive. The product of any number of positive factors is positive.
The product is positive.
The width of a rectangle is 7ft less than the length. The area of the rectangle is 228 square feet. Find the length and width
Set up figure, side length x, and width x-7. Set equation up
[tex]228 = (x)(x - 7) \\ 228 = {x}^{2} - 7x \\ {x}^{2} - 7x - 228 = 0 \\ (x - 19)(x + 12) = 0 \\ x = - 12 \\ x = 19[/tex]
Since the value x, cannot be negative, x is equal to 19. Therefore the length is 19, width 12 (19-7)

Rewrite in simplest terms: (-8x– 6y) + (6x – 3y)
Answer:
-5x - 6y
Step-by-step explanation:
Firstly, you remove any uncessary parentheses and collect like terms.
So that becomes -8x - 6y + (3x)
Hence, the brackets can be removed, which means we can continue to collect like terms which gives the final answer of -5x - 6y

Answer:
[tex] y = -\dfrac{11}{2}x - 52 [/tex]
Step-by-step explanation:
Line through points (-10, 3) and (-8, -8).
slope = (-8 - 3)/(-8 - (-10)) = -11/2
y = mx + b
y = (-11/2)x + b
-8 = (-11/2)(-8) + b
-8 = 44 + b
b = -52
y = (-11/2)x - 52
A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the line passing through (-10,3) and (−8, -8) is y=(-11/2)x-52.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The slope fo the line passing through (-10,3) and (−8, -8) is
Slope, m = (-8-3)/(-8+10) = -11/2
Now, equate a point in the equation,
3 = -10(-11/2) + C
3 = 55 + C
c = -52
Hence, the equation of the line passing through (-10,3) and (−8, -8) is y=(-11/2)x-52.

Question 8 Tasha noticed that bags are not selling quite well. She reduced the original price of $300 by 20%. After, three months the bags were still not selling.She reduced the price again by 40%. A, What was the total percent of decrease? Show your work.
Answer:
84% decrease
Step-by-step explanation:
100 - 80 = 20%
80% = 4/5
300 * 4/5 = 240
100 - 40 = 60%
60% = 3/5
240 * 3/5 = 48
48/300 = 4/25 = 16%
100 - 16 = 84%

Using the unit circle, determine the value of sin 450°
Answer:
To find the value of sin 450 degrees using the unit circle, represent 450° in the form (1 × 360°) + 90° [∵ 450°>360°] ∵ sine is a periodic function, sin 450° = sin 90°.
Answer:
1
Step-by-step explanation:
To find the value of sin 450 degrees using the unit circle, represent 450° in the form (1 × 360°) + 90° [∵ 450°>360°] ∵ sine is a periodic function, sin 450° = sin 90°.
Rotate ‘r’ anticlockwise to form a 90° or 450° angle with the positive x-axis.
The sin of 450 degrees equals the y-coordinate(1) of the point of intersection (0, 1) of unit circle and r.
Hence the value of sin 450° = y = 1

At a school 60% of students buy a school lunch. Only 10% of students buy lunch and dessert. What is the probability that a student who buys lunch also buys dessert?
Answer:
1/6
Step-by-step explanation:
P(A) = probability a student buys lunch = 60% = 0.6
P(B) = probability a student buys lunch and dessert = 10% = 0.1
We are looking at the probability that a student buys lunch and dessert on the condition that they already bought lunch. Therefore, we are looking at a conditional probability.
P(B given A) = P(A and B) / P(A)
= 0.1 / 0.6
= 1/6 ≈ 0.167
combine the like terms in the equation : 2s-4w+5+6s
To combine like terms, you have to add the same variables and all
First You have to find if the Numbers are positive or Negative
2s is positive
4w is Negative because i has Minus sigh before it
5 is Positive because it has added sigh
6s s Positive because it has added sign
Second you have to find the Like terms
2s+6s=8s
so, the new equation is
8s-4w+5.
That is the simplest

Please answer please help me
Answer:
see explanation
Step-by-step explanation:
(1)
[tex]\frac{5}{60}[/tex] ( divide numerator/ denominator by 5 )
= [tex]\frac{1}{12}[/tex] ( in simplest form )
(2)
both quantities must have the same units
1 hour = 60 minutes , then
[tex]\frac{60}{40}[/tex] ( divide numerator/ denominator by 20 )
= [tex]\frac{3}{2}[/tex] ( in simplest form )
(3)
1 week = 7 days then 2 weeks = 2 × 7 = 14 days , so
[tex]\frac{14}{4}[/tex] ( divide numerator/ denominator by 2 )
= [tex]\frac{7}{2}[/tex] ( in simplest form )
(4)
[tex]\frac{8}{30}[/tex] ( divide numerator/ denominator by 2 )
= [tex]\frac{4}{15}[/tex] ( in simplest form )
(5)
[tex]\frac{9}{45}[/tex] ( divide numerator/ denominator by 9 )
= [tex]\frac{1}{5}[/tex] ( in simplest form )
