Select the statement that describes the following expression 6 x (2 + 7) − 9.
A) 6 times the sum of 2 and 7, then subtract 9
B) 6 times the product of 2 and 7, then add 9
C) 6 times the difference of 2 and 7, then subtract 9
D) 6 times the sum of 2 and 7, then add 9
Answer:
A) 6 times the sum of 2 and 7, then subtract 9
Step-by-step explanation:
At the end of the given expression, there is a " - 9", which means that the 9 is getting subtracted. From this you can cancel out answer choices B and D because they add 9.
In the expression, there is a (2 + 7), which means that the 2 and the 7 are being added together, producing a sum. That cancels out answer choice C, leaving choice A.
Answer:
Step-by-step explanation:
Order of operation rules require that we do all work inside parentheses first, and then multiplication/division, and only then addition and subtraction.
We evaluate (2 + 7) first, obtaining 9, and then have 6·9 - 9.
This multiplication must be done before the subtraction, so we get:
54 - 9 = 45 This corresponds to Answer A.

Of flowers in a field 43% are yellow . The others are white. A bee randombly lands on a flowerdescribe the complelment of the bee landing on a yellow flower. Determine its probability
Answer:
0.43
Step-by-step explanation:
Yellow flowers are 43%.
White flowers are = (100% - 43% ) = 57%
Consider there are total 100 flowers in the garden , so yellow ones are 43 and white ones are 57
Probability of a bee landing on a yellow flower is 43 out of 100
= 43/ 100
=0.43
i am genuinely lost ..... pls dont give me pdfs or links
There are 25% more 7th graders than 6th graders in band. If there are 135 total 6th and 7th graders in the school band, how many 6th graders are in band?
Answer:
There are 60 6th graders in band.
Step-by-step explanation:
Let x represent the number of 6th graders in band. If there are 25% more in 7th grade, you can write it as (5/4)x. (You could also say 1.25x, but I think fractions would be easier in this situation.) Set up an equation:
x+(5/4)x=135
Now solve for x.
(4/4)x+(5/4)x=135
(9/4)x=135
(1/4)x=15
x=60
There are 60 6th graders in band.
Hope I could help you!

Can someone tell me three events that have a probability of 0 (zero) and why?
Step-by-step explanation:
A probability of zero means things are impossible to happen.
For example,
Today is Monday so Tommorow is Friday I'm 17 today and I turn 28 tomorrow on my birthday.Throwing a 7 using a six sides dice.All of those above are impossible to happen.The box plot summarizes the number of goals scored at a basketball game. State the least
value, the median, the lower quartile, and the upper quartile. Then, find the interquartile range.
HA
16 18 20 22 24 26 28 30 32 34
Number of Goals
Median
Upper Quartile:
Lower Quartile: I
Interquartile Range:
Answer:
Median: 25
Upper quartile: 30
Lower quartile: 20
IQR: 10
Step-by-step explanation:
The nice thing here is they already put them in order :)
16, 18, 20, 22, 24, 26, 28, 30, 32, 34
For the median, it's the middle number of the ordered data set. Unfortunately here, there is an even number of entries. In that case, we average the middle two numbers, 24 and 26. 24 + 26 = 50/2 = 25
For lower quartile/Q1, you take the middle number of the bottom half of the data set. Bottom half: 16, 18, 20, 22, 24...so the middle is 20
For the upper quartile/Q3, you take the middle number of the top half of the data set. Upper half: 26, 28, 30, 32, 34...so the middle is 30
For interquartile range/IQR, you calculate the range from third to first quartile: 30-20 = 10

Can two angles be both vertical and adjacent? Explain why or why not?
Answer:
no then can not be both
Step-by-step explanation:
vertical angles require the intersection of 2 straight lines and then they are the opposite of where they intersect
adjacent are next to each other
Answer:
no, vertical angles can never be adjacent. adjacent angles are the ones next to each other while vertical angles are opposite from each other

the width of a rectangle is represented by 2x, and the length is represented by x2 ->
- x + 3. Which expression represents the area of the rectangle?
Answer:
x2 ->
Step-by-step explanation:
Width area = long edge × short edge
= (2+3x).(x-4)
= 2x-8+3x²-12x
= 3x²-8-10x
= 3x²-10x-8
= x2 ->
What value of x makes this true 1.5x=120?
Answer: 80
Step-by-step explanation:
x.3/2 = 120
x = 120.2/3
x=80

The volume of this pyramid is 36.67 m3. If the area of its base is 10.0 m2, how high is the pyramid? Round to the nearest whole meter. a) 4 m b) 11 m c) 5m d) 12 m
Answer:
b
Step-by-step explanation:
A pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle
The volume of a pyramid = 1/3 × (area of base x height)
volume = 36.67 m3
area = 10.0 m2,
height = ?
36.67 = 1/3 x (10 x h)
multiply both sides of the equation by 3
110.01 = 10h
divide both sides by 10
h = 11.0001 m
Pretty please HELP MEEEE A circular flower bed is 19 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi.
SA is the area of flowerbed
radius is 9.5 m (diameter, 19, divided by 2)π(r)²3.14(9.5)²3.14(90.25)SA = 283.385 m²LA is the large area of both flowerbed and sidewalk together
Adding 9.5 and 3 together, the total radius is 12.5 mπ(r)²3.14(12.5)²3.14(156.25)LA = 490.625 m²Subtract SA from LA in order to find teh area of sidewalk.
A = 283.385 - 490.625 = 207.24 m²
ANSWER: 207.24 m² is the area of the sidewalkWhat is the solution of (x+8)/(5x+-1)>0?
Answer:
the solution set is (-infinity, -8) ∪ (-8, 1/5)
Step-by-step explanation:
x + 8 changes sign at x = -8.
I'll assume you meant 5x - 1 (as 5x+- is meaningless). 5x - 1 changes sign at x = 1/5.
Subdivide the x-axis using the two x-values found above:
(negative infinity, -8), (-8, 1/5), (1/5, infinity.
Choose a representative value from each interval. I'm choosing x = -10, x = 0 and x = 1.
Now test the given inequality at each of these x-values. Is the result true or false?
x + 8
---------- > 0
5x - 1
For x = -10:
-10 + 8
--------------- > 0 => -2/(-51) => 2/51 This is TRUE
5(-10) - 1
For x = 1:
1 + 8
---------- > 0 => 9/4 This is TRUE
5 - 1
For x = 0:
8
---------- > 0 This is FALSE
- 1
Therefore the solution set is (-infinity, -8) ∪ (-8, 1/5)

How many one-inch cubes will fit in the box?
Answer:
D. 132,651 cubes
Step-by-step explanation:
You're looking for how many cubes fit in the box. Remember cubic means 3 dimensions and squared means 2 dimensions.
Use length x width x height and converting the 4.25 feet to inches...
4.25×12=51
51×51×51=132,651
Meaning 132,651 one inch cubes would fit.
Answer:
132,651 cubes
Step-by-step explanation:
4.25 ft = 51 inches
51 x 51 x51 = 132,651 inches
1 x 1 x 1 = 1 inch cubes
so
132,651 divided by 1 = 132,651.
