a – 16 = 24 simple equation
Answer:
40
Step-by-step explanation:
16+24=40
40-16=24
Answer:
a = 40
Step-by-step explanation:
Add 16 on both sides
a - 16 + 16 = 24 + 16
a = 24 +16 = 40
a = 40
Verification
LHS = a - 16 a = 40
40 - 16 = 24
RHS = 24
Both LHS and RHS are same so, our answer is correct.

B. ±169/16
C. No solution
D. ±4/13
Answer:
Option D, [tex]x =[/tex] ± [tex]4/13[/tex]
Step-by-step explanation:
Step 1: Add 16 to both sides
[tex]169x^2 - 16 = 0[/tex]
[tex]169x^2 - 16 + 16= 0 + 16[/tex]
[tex]169x^2 = 16[/tex]
Step 2: Divide 169 from both sides

Answer:
Step-by-step explanation:
Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the x-axis and time on the y-axis. The slope will be 2.2 at every point along her bike ride.
Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

We-Haul rents a moving truck for $20.00 and $0.45 per mile. You-Haul rents the same size moving truck for $1.00 per mile but with no upfront charge.
Let c represent the overall cost for renting the moving truck.
Let m represent the miles traveled.
Which of the following statements are true about this situation? Select all that apply.
a
The following equations could be used to represent the situation: c = 0.45m + 20 c = 1.00m
b
The y-intercepts of each line represent the upfront charge to rent the moving truck.
c
At 38 miles, We-Haul would be a better deal.
d
The two truck rentals will cost the same around mile 35.36
e
The rate of change for You-Haul is larger than the rate of change for We-Haul
Answer:
*select all that apply*
All of these are true
Step-by-step explanation:
Answer choice A:
We-Haul: c = 0.45m + 20
You-Haul: c = 1m
--> TRUE
Answer Choice B:
the y-intercept is the upfront charge bc the charge for "per mile" is attached to "mx" and the "b" (y-intercept) is the upfront charge
--> TRUE
Answer choice C:
We-Haul -
c = 0.45(38) + 20 = $37.10
You-Haul -
c = 1m = $38.00
--> TRUE
answer choice D:
We-Haul -
c = 0.45(35.36) + 20 = $35.91
You-Haul -
c = 1m = $35.36
Since the two costs are very close to being the same, I think this is a true statement also
--> TRUE
Answer choice E:
You-Haul's rate is 1 mph whereas We-Haul's rate is 0.45mph. You-Haul's rate is 0.55 larger than We-Haul's
--> TRUE
Hope this helps :)
Find the arc length of the partial circle.
Either enter an exact answer in terms of \piπpi or use 3.14 π and enter your answer as a decimal.
Answer:
arc = 7.5π units
Step-by-step explanation:
the arc length is calculated as
arc = circumference of circle × fraction of circle
the angle subtended at the centre by the arc is 360° - 90° = 270° , then
arc = 2π × 5 × [tex]\frac{270}{360}[/tex]
= 10π × [tex]\frac{3}{4}[/tex]

Answer:
20 inmates should leave
Step-by-step explanation:
A camp having 80 inmates, has food sufficient for 70 days.

What is the total area of the figure? (square inches)
Answer:
60
Step-by-step explanation:
TOTAL SURFACE AREA = AREA OF SQUARE+2×(AREA OF TRIANGLE)
=(6×6)+2×(1/2×6×4)
=36+24=60 square inches
I hope it helped you
Answer:
The area of the full figure is 60 square inches.
Step-by-step explanation:
There are 4 triangles and one square in this figure. We can start by figuring out the area of the middle square, which would be [tex]6*6=36[/tex] because we know the sides are all 6 inches.
Next, we can look at the triangles and see that their hypotenuses (the longest sides) are all the same length, that being 5 inches. This means that we only need to find the length of the third side and then multiply the area of one triangle by 4 to get the area of all the triangles.
The pythagorean theorem states that in any right triangle, [tex]a^2 +b^2=c^2[/tex], with [tex]c^2[/tex] being the length of the hypotenuse. Since we know the length of the hypotenuse is 5 and one of the legs of the triangle is 4, we can insert this into the equation: [tex]a^2+4^2=5^2[/tex], which when simplified all the way gives us that [tex]a=3[/tex].
Since a right triangle is half of a rectangle, the easiest way to find the area of the triangle is to multiply the measures of the two legs together and then divide by two: [tex](3*4)/2=6[/tex]. Therefore, we know that each triangle in the picture has an area of 6.
Finally, you need to add all of the areas together to find the area of the full figure: [tex]36+6+6+6+6=60 in^2[/tex]
The area of the full figure is 60 square inches.
Hope this helps! :)

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER what is the value of X in simplest radical form?
X=_____
Answer:
x= 29
Step-by-step explanation:
use Pythagoras because it has a right angle and 2 sides length is given.
when the hypoteneus(side opposite the right angle) is the value you are finding out you use the equation : x²+y²=hypoteneus² (Pythagoras)
then you sub in the values you are given
(21)² + (20)² = hypoteneus²
them take the square root (²) to the opposite side to find the hypoteneus
square root (441+400) = hypoteneus
now you can put into a calculator and you get the value
hypoteneus =29 (for reference to hypoteneus is the same as X-the value you are looking for)
therefore, x=29
for extra reference, say you want to work out a side that is not the hypotenues you use the formula ,
(side u looking for)² = (hypotenues)² - (other side given)²
Answer:
x = 29
Step-by-step explanation:
To find x, we can use the Pythagorean theorem.
a^2 + b^2 = c^2
21^2 + 20^2 = x^2
441 + 400 = x^2
841 = x^2
[tex]\sqrt{841}[/tex] = [tex]\sqrt{x^2}[/tex]
29 = x
Find the growth or decay percentage y= 18(0.914)m
The function y = 18(0.914)^m is having exponential decay. The decay percent of this function is 8.6%
What is exponential growth or decay function?Consider the function:
[tex]y = a(1\pm r)^m[/tex]
where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is plus sign, then there is exponential growth happening by r fraction or 100r %
If there is negative sign, then there is exponential decay happening by r fraction or 100r %
For this case, the exponential growth/decay function given is:
[tex]y = 18(0.914)^m[/tex]
That means, there is multiplication of (0.914) for each growth/decay.
We can rewrite 0.914 as:
0.914 = 1 - 0.086
This shows decay as multiplication with 0 < quantity < 1 makes the number less in magnitude.
A quantity times (1 - 0.086) = that quantity - that quantity times 0.086
and we can write 0.086 = 8.6/100 = 8.6%
Thus, we're decreasing 8.6% each time from a quantity when we multiply that quantity with (1-0.086)
Thus, there is exponential(exponential because of the presence of variable 'm' as exponent in the given function) decay of 8.6%.

What is the median number of words in Darcy's essays?
Answer:
210.8 (mean for Luis), 241.5 (mean for Darcy)
Step-by-step explanation:
Luis 178 + 213 + 198 + 245 + 236 + 198 + 221 + 253 + 189 + 177 = 2108
2108/10 = 210.8 (mean for Luis)
Darcy 231 + 210 + 245 + 259 + 286 + 245 + 231 + 244 + 236 + 228 = 2415
2415/10 = 241.5 (mean for Darcy)
Answer:
To find the median number of words in Darcy’s essays, first arrange the values in the data set in ascending order:
210, 228, 231, 231, 236, 244, 245, 245, 259, 286.
Because the number of values in the data set is an even number (10), the median is the mean of the two middle values, the fifth and sixth values, in the data set. The fifth and sixth values are 236 and 244, respectively. So,
median

Using the given discrete probability distribution, it is found that the probability that a randomly selected student has a grade higher than a C is given by:
P(X > 2).
What is the discrete probability distribution for the grade?From the table, it is given by:
P(X = F) = P(X = 0) = 0.04.P(X = D) = P(X = 1) = 0.05.P(X = C) = P(X = 2) = 0.17.P(X = B) = P(X = 3) = 0.31.P(X = A) = P(X = 4) = 0.43.Grades A and B are greater than C, hence the probability of getting a grade higher than C is given by:
P(X > C) = P(X = A) + P(X = B) = P(X = 3) + P(X = 4) = P(X > 2).
