Answer:
-9
Step-by-step explanation:
Using the sum/difference property of logarithms, we can rewrite the expression given as:
log b^3 + log c^3 - log √(a^3) --> log √(a^3) can also be written as log a^1.5
Next, we can use the power property of logarithms, and rewrite it again as:
3log b + 3log c - 1.5log a
Now, we can substitute the values of log a, log b, and log c:
3(11) + 3(-9) - 1.5(10)
33 - 27 - 15
-9
Simplifying, we get -9 as the answer.
HELP
In complete sentences, explain why correlation does not prove causation. Please have at least 3 complete sentences with proper punctuation, grammar, and capitalization.
Answer:
Correlation doesn't prove causation because just because two things correlate does not necessarily mean that one causes the other.It's easy to think that just because two things seem related, that one must be the cause of the other. But that can be a foolish and sometimes dangerous assumption
I need to know the surface area of this prism please help !!!! I will give brainlist !
Answer:
614
Step-by-step explanation:
15 x 13 = 195 two times 195 x 2 = 390
4 x 15 = 60 two times 60 x 2 = 120
4 x 13 = 52 two times 52 x 2 = 104
104 + 120 + 390 = 614
Answer:
SA = 2(l·w)+2(w·h)+2(l·h)
SA = 614 sq in
Step-by-step explanation:
SA = 2(4x13)+2(13x15)+2(4x15)
= 2(52)+2(195)+2(60)
= 104 + 390 + 120
= 614

7th grades math help me pleaseeee
Answer:
7 attendees
Step-by-step explanation:
From the above question, we know that:
$10 = 5 attendees
$14 = x
Cross Multiply
$10 × x attendees = $14 × 5 attendees
x attendees = $14 × 5 attendees/$10
x attendees = 7 attendees
Therefore, if the budget for the cooperate team building is $14, the number of attendees is 7

Shows the termination of the parking lot of Helen healings health food store parking lot is how many square yards
Answer:
1100 yd²
Step-by-step explanation:
The parking lot can be divided into 2 rectangles :
Area of a rectangle = Length * Width
First rectangle :
Dimension = 40 yards by 20 yards
Area = 40 * 20 = 800 yd²
Rectangule 2 :
30 yards by 10 yards
Area = 30 * 20
Area = 30 * 10 = 300 yd²
Total area of parking lot :
800 + 300 yd²
= 1100 yd²
Help me with this question, please!
Answer:
3,432 m²
Step-by-step explanation:
The amount of aluminum in square meters needed to make the mailboxes = 1863(surface area of each mailbox)
Surface area of each mail box = ½(surface area of cylinder) + (Surface area of rectangular prism/box - area of the surface of the box that joins the half-cylinder)
✔️Surface area of ½-cylinder = ½[2πr(h + r)]
r = ½(0.4) = 0.2 m
h = 0.6 m
π = 3.14
Surface area of ½-cylinder = ½[2*3.14*0.2(0.6 + 0.2]
= 0.628(0.8)
Surface area of ½-cylinder = 0.5024 m²
✔️Surface area of the rectangular box/prism = 2(LW + LH + WH)
L = 0.6 m
W = 0.4 m
H = 0.55 m
Surface area = 2(0.6*0.4 + 0.6*0.55 + 0.4*0.55)
Surface area of rectangular box = 1.58 m²
✔️Area of the surface joining the half cylinder and the box = L*W = 0.6*0.4 = 0.24 m²
✅Surface area of 1 mailbox = (0.5024) + (1.58 - 0.24)
= 0.5024 + 1.34
= 1.8424
Amount of aluminum needed to make 1863 mailboxes = 1863 × 1.8424 = 3,432.3912
= 3,432 m²
A circle has a radius of 1.5 meters.
Find its circumference and area.
help bestiess :)
Answer:
C=9.42
Step-by-step explanation:
Formulas: C=2πr or C=πd
Were gonna use C=2πr
"r"stands for radius from the problem we know that the radius is 1.5 .
Now we substitute the "r" for 1.5, it looks like this C=2π1.5 .
Now we multiply 2x1.5=3 . Now you are left with C=3π
Now you need to multiply 3xπ (Instead of π use 3.14) it would look like this 3x3.14= 9.42

Calculate the area of the polygon.
A) 48 units squared
B) 53 units squared
C) 68 units squared
D) 88 units squared
Answer:
B hope this helps!
Step-by-step explanation:
Trust <3
Answer:
The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.
The searched polygon can be seen in the attached image.
The area of the polygon will be the area of the square plus the area of the triangle.
At = (6) * (8) + (1/2) * (5) * (8) = 68
At = 68
answer
the area of the polygon is 68units ^ 2

10. Tamara wants to find the height of a tree outside her home. Using her clinometer, she measures the slope angle from 8 feet away from the base of the tree and gets an angle of 40o . If Tamara's eye level is 5 feet above the ground, how tall is the tree (rounded to the nearest tenth of a foot)? Show your work.
Answer:
11.7 ft
Step-by-step explanation:
Remember the notation SOHCAHTOA
We would be using tan because we have been given the adjacent and we are to determine the opposite value
tan 40 = opposite / adjacent
0.8391 = opposite / 8
opposite = 0.8391 x 8
6.7
Tamera is 5 ft above ground = 6.7 + 5 = 11.7 foot
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

What is the equation in slope-intercept form
of the line that passes through the points
(-3, 10) and (3, 14)?
Answer:
C) y=2/3x+12
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(14-10)/(3-(-3))
m=4/(3+3)
m=4/6
simplify
m=2/3
y-y1=m(x-x1)
y-10=2/3(x-(-3))
y-10=2/3(x+3)
y=2/3x+6/3+10
y=2/3x+2+10
y=2/3x+12
"-3x" + 5 < "-10" Inequality 2: 7x + x - 4 > 28 Which of the following values makes BOTH inequalities TRUE? Select all that apply! 12 "-5" −152 "-8.25" 23 48 325
Answer:
12, 23, 48, 325
Step-by-step explanation:
So, when given two inequalities and asked to find the values that make both true, it is considered a system of equations. To solve a system of equation, you have to graph the inequalities and find where they intersect.
Inequality 1:
(-3x) + 5 < (-10)
Inequality 2:
7x + x - 4 > 28
simplifies to: 8x - 4 > 28
When graphed, the inequalities don't intersect, but rather have a similar shaded area overlapping from the point of 5 and greater.
Answers that apply from given list would be:

A. Linear
B. Quadratic
C. Exponential
D. No pattern
Answer:linear
Step-by-step explanation:
it is a straight line
The best-fitting regression model for the scatterplot is linear. Thus, the correct answer is an option (A).
As per the given figure, the data points on a scatterplot, with the dependent variable (y-axis) plotted against the independent variable (x-axis).
Looking at the general pattern of the data points on the scatterplot.
Here, they follow a roughly linear trend.
This means that the data points roughly form a straight line or a curve that looks like a straight line.
Thus, the best-fitting regression model for the scatterplot is linear.
Hence, the correct answer is option (A).

Is the function below linear or non linear? y = 5 + 3(x-4)
Answer:
Linear
Step-by-step explanation:
The rule is that linear equations must have exponents of 1 (a sloped line) or 0 A verticle or horizontal line). This function can be simplified to
y = 3x - 12 + 5 = 3x - 7 which is the standard form of a linear equation
y - mx + b where m is the slope and m is the y intercept.
