I think it might be 143 I could be wrong tho.
9514 1404 393
Answer:
143 maps
Step-by-step explanation:
The total number of students is ...
3×29 + 2×28 = 87 +56 = 143
If each student gets a map, the number of maps needed is 143.
_____
Additional comment
You might be able to figure this in your head as ...
3×29 +2×28 = 3×(28+1) +2×28 = 5×28 +3 = 140 +3 = 143
Or as ...
3(30 -1) +2(30 -2) = 5(30) -3 -4 = 150 -7 = 143

IS A PICTURE!!!! thank you for your time
Answer:
I am not sure, but I think you would check for the side with the longest length(hypothenuse) and check if the formula of a^2+b^2=c^2(side with the longest length) satisfies it.

What is the volume of this composite solid?
Step-by-step explanation:
5×9×12=540
6×9×12÷2=324
324+540=864
Answer:
C. 1188 cubic meters
Step-by-step explanation:
"To find the volume, we must multiply the length x width x height"
The shape is too big so we must break it into another shape
Let's solve the bottom shape that looks like a rectangle!
Length: 12 m
Width: 9 m
Height: 5 m
Volume = 540 m
Now the top shape!
Length: 12 m
Width: 9 m
Height: 6 m
Volume = 648 m
Now we need to add both of the volume shapes!
648 + 540 = 1188 cubic meters
Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour while the other travels at 105miles per hour. How long will it take for the two trains to meet?
Answer:
let x=distance 105 mph train traveled
(456-x)=distance 85 mph train traveled
Travel time = distance/speed (equal in both directions)
x/105=(456-x)/85
85x=105*456-105x
190x=105*456
x=105*456/190=252 miles
travel time=252/105=2.4 hrs
ans:
The two trains will meet in 2.4 hrs

What is 5C3?
A. 35
B. 10
C. 14
D. 28
Answer: B. 10
-5C3 or 5 choose 3 refers to how many combinations are possible from 5 items, taken 3 at a time. To calculate combinations, we will use the formula nCr = n! / r! ... * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.
-10 is the total number of all possible combinations for choosing 3 elements at a time from 5 distinct elements without considering the order of elements in statistics & probability surveys or experiments. The number of combinations for sample space 5 CHOOSE 3 can also be written as 5C3 in the format of nCr or nCk.

Which of the following situations can be represented by C = 10 + 0.44n?
Answer:
10.44
Step-by-step explanation:
Find the domain D and range R of the function f(x)=|9+2x|. (Use symbolic notation and fractions where needed. Give your answers as intervals in the form (∗,∗). Use the symbol [infinity] for infinity and the appropriate type of parenthesis "(", ")", "[", or "]" depending on whether the interval is open or closed.)
Answer:
Domain of the function 'f' → [tex](-\infty,\infty)[/tex]
Range of the function 'f' → [tex][0,\infty)[/tex]
Step-by-step explanation:
Parent function of an absolute function is,
g(x) = |x|
Domain of the parent function → [tex](-\infty,\infty)[/tex]
Range of the parent function → [tex][0,\infty)[/tex]
If the function 'g' is vertically stretched by a factor of 2, the new function will be,
h(x) = |2x|
Function 'g' is translated by 9 units to the left, then the new function will be,
f(x) = |2x + 9|
By shifting the parent function on x-axis domain of the function will remain same as of the parent function.
Domain of the function 'f' → [tex](-\infty,\infty)[/tex]
Since, there is no shifting along the y-axis therefore, Range of the function will remain the same as the parent.
Range of the function 'f' → [tex][0,\infty)[/tex]
A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative. Round answers to 4 decimal places where possible.
Answer:
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
Of the 533 randomly selected Americans surveyed, 351 were in favor of the initiative.
This means that [tex]n = 533, \pi = \frac{351}{533} = 0.6585[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 - 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6247[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6585 + 1.645\sqrt{\frac{0.6585*0.3415}{533}} = 0.6923[/tex]
The 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative is (0.6247, 0.6923).

Exact Form: -53/12
decimal form: -4.416
mixed number -4 5/12
Step-by-step explanation:
convert mixed numbers into improper fractions: -2 3/3 +(5 1/2)+ 8 3/4
convert mixed numbers into improper fractions: =11/2 =[tex]-\frac{23}{3}+\left(-\frac{11}{2}\right)+\frac{35}{4}[/tex] =
[tex]-\frac{23}{3}+\left-\frac{11}{2}\right+\frac{35}{4}[/tex][tex]=-\frac{92}{12}-\frac{66}{12}+\frac{105}{12}[/tex]
[tex]\frac{-92-66+105}{12}[/tex]
add/subtract the numbers: -92-66+105=-53
-53/12
apply the fraction rule: [tex]\frac{-a}{b} = -\frac{a}{b\\}[/tex]
[tex]=-\frac{53}{12}\\[/tex]

The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested. A) What is the median value of each data set? B) Compare the median values of the data sets. What does this comparison tell you in terms of the situation the data represents? ( Answer A and B) Will Mark Brainliest if correct answer.
Answer:
X = 13 ; Y = 16
Median Y > Median X
Battery Y lasts longer and hence better than Battery X.
Step-by-step explanation:
From the box plot, median value is the point marked by the vertical line in between the box located between the whiskers.
Median :
Brand X = 13
Brand Y = 16
This median value depicts that, average battery life of brand X batteries is 13 hours while that of brand Y batteries is 16 hours ; Median value of Y is greater Than median value of X ;
This means Brand Y batteries lasts longer on average than Brand X batteries.

Answer:
x = 148
Step-by-step explanation:
vertical angles are congruent
the angle with a measure of 148° and the angle labeled "x" are vertical angles.
Hence, x = 148
Answer:
x=148 because the opposite angles are equal
also, the rest of the smaller angles are both 32 degrees if you need them
you can check because 148+148+32+32=360
hope it helps:)

What equation models the volume for a rectangular prism that is 4 cm long, 4cm wide, and 0.1 m tall A. V = 42 x 10 B. V = 10 x (4 + 4) C. V = 400 x 4 D. V = (4 x 4) + 10
Answer:
It's 160
I think you have a typo in d. If you do, the answer is d) V=(4 x 4) x 10
meaning a x 10 versus a + 10 as typed.
Step-by-step explanation:
.1m=10cm
volume = 4 x 4 x 10 = 160

Help me with number 10 pleaseeeeeeeeee
Answer:
4' - 9.64
Step-by-step explanation:
Total rise = 2' - 7"
Total run = 3' - 9"
Converting to inches :
1' = 12" ; 1 feet = 12 inches
2' = 2 * 12 = 24"
3' = 3 * 12 = 36"
Total rise = 24" + 7" = 31"
Total run = 36" + 9" = 45"
Length of stringer = hypotenus
Hypotenus = √(total rise² + total run²)
Hypotenus = √(31² + 45²)
Hypotenus = 54.644304"
= 4' - 9.64"
