can someone help me
ty
a.
Answer:
1170cm^3
Step-by-step explanation:
Break it into two prisms. 5 x 9 x 15 and 11 x 3 x 15. Find the volume of each and add.
(5 x 9 x 15) + (11 x 3 x 15)
675 + 495
1170cm^3
b.
Answer:
846cm^2
Step-by-step explanation:
Add each side's area together.
(9x15) + (5x15) + (6x15) + (3x15) + (12x15) + (11x15) + (5x9) + (5x9) + (11x3) + (11x3)
135 + 75 + 90 + 45 + 180 + 165 + 45 + 45 + 33 + 33
846 cm^2
Answer:
(a)1170 cm^3
(b)846 cm^2
Step-by-step explanation:
(a) Rectangle #1= 11 x 3 = 33 cm^2
Rectangle #2 = 5 x 9 = 45 cm^2
Volume = 45 + 33 = 78 x 15 = 1170 cm^3
(b) First find the surface are of all 8 faces in the prism and then add them all.
1st face = (11 x 3) + (5 x 9 ) = 33 + 45 = 78 cm^2
2nd face = (11 x 3) + (5 x 9 ) = 33 + 45 = 78 cm^2
3rd face = 15 x 3 = 45 cm^2
4th face = 15 x 6 = 90 cm^2
5th face = 15 x 9 = 135 cm^2
6th face = 15 x 5 = 75 cm^2
7th face = 15 x 12 = 180 cm^2
8th face = 15 x 11 = 165 cm^2
1st + 2nd + 3rd +4th + 5th+ 6th + 7th + 8th = 846 cm^2
Hope this helps!

Step-by-step explanation:
We have,
[tex]g(x)=x^3+x^2-x-2[/tex]
To find g(-1), put -1 in place of x i.e.
[tex]g(-1)=(-1)^3+(-1)^2-(-1)-2\\\\=-1[/tex]
To find g(1), put 1 in place of x i.e.
[tex]g(1)=1^3+1^2-1-2\\\\=-1[/tex]
To find g(2), put 2 in place of x i.e.
[tex]g(2)=2^3+2^2-2-2\\\\=8[/tex]
g(2) + g(1) = 8+(-1)
= 7
Hence, this is the required solution.

Step-by-step explanation:
Prove that if a and b are positive integers,then there exists a unique integers q and r such that a=bq+r where 0≤r<b
Step-by-step explanation:
Correct option is
C
0≤r<b
If r must satisfy0≤r<b
Proof,
..,a−3b,a−2b,a−b,a,a+b,a+2b,a+3b,..
clearly it is an arithmetic progression with common difference b and it extends infinitely in both directions.
Let r be the smallest non-negative term of this arithmetic progression.Then,there exists a non-negative integer q such that,
a−bq=r
=>a=bq+r
As,r is the smallest non-negative integer satisfying the result.Therefore, 0≤r≤b
Thus, we have
a=bq1+r1, 0≤r1≤b
Clara, Dean and Elaine were candidate in an election in which 1000 people voted.elaine won the election receiving 95 more votes than Dean,and 186 more than Clara. how many votes did dean receive?
Answer:
E = 427 votes
Step-by-step explanation:
Let Elaine's vote be ELet Dean's vote be DLet Clara's vote be C.Translating the word problem into an algebraic expression, we have;
E = D + 95
E = C + 186
Equating the two equations, we have;
D + 95 = C + 186
D = C + 186 - 95
D = C + 91
Also, the sum of all the votes is equal to 1000.
E + D + C = 1000
Substituting the value of "D" we have;
E + (C + 91) + C = 1000
E + C + 91 + C = 1000
E + 2C + 91 = 1000
E + 2C = 1000 - 91
E + 2C = 909
But, E = C + 186
Substituting the value of "E" we have;
(C + 186) + 2C = 909
C + 186 + 2C = 909
3C + 186 = 909
3C = 909 - 186
3C = 723
C = 723/3
C = 241 votes
Next, we would find Elaine's vote;
E = C + 186
E = 241 + 186
E = 427 votes
Lastly, we would find Dean's vote;
E = D + 95
427 = D + 95
D = 427 - 95
D = 332 votes
Check:
E + D + C = 1000
427 + 332 + 241 = 1000
1000 = 1000
What is the value of x?
O x = 32
O x = 36
O x = 37
O x = 40
Answer:
x=40
Step-by-step explanation:
I went through each answer one by one and the only one that satisfies the question is 40.
The line equals 180°, so x + (4x-20) must equal 180.
x+(4x-20)
40+(4(40)-20)
40+(160-20)
40+140=180
x=40
Answer:
x= 40
Step-by-step explanation:
sum of angle on a straight line= 180;
To find X,
sum of angles = 180
x+(4x-20)= 180
: x= 180- [x+(4x-20)]
opening the brackets,
= 180-x-4x+20= 0
taking like terms:
= -x-4x+180+20= 0
= -5x+200=0
= -5x= -200
= x= 200/5
x= 40°
A rectangle has vertices (−5, 6), (−1, 6), (−1, 3), and (−5, 3). It is first dilated by the rule (x, y)→(7x, 7y) and then translated 10 units down. What are the coordinates of the image?
A(−35, 32), (−7, 32), (−7, 11), (−35, 11)
B(−45, 42), (−17, 42), (−17, 21), (−45, 21)
C(−105, 42), (−77, 42), (−77, 21), (−105, 21)
D(−35,−28), (−7,−28), (−7,−49), (−35,−49)
An electrician needs 4 7/10 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 9 2/5 rolls of wire?
Answer:
2 rooms
Step-by-step explanation:
Let; 4 7/10 = 47/10
9 2/5=47/5
So; if each room(1) = 47/10
47/5 should be x rooms
Equation form47/10 = 1
47/5 = x
cross multiplying
47/10x = 47/5
L.C.M = 10
10×47/10x = 10× 47/5
47x = 47 × 2
x = 47 × 2/47
x = 2
Therefore x being 9 2/5 rolls of wire will wire 2 rooms
Given the triangle below, what is the length of the third side, rounded to the
nearest whole number?
B
18
A
12
620
Triangle not drawn to scale
A. 18
B. 14
C. 16
D. 20
Answer:
Option C
Step-by-step explanation:
In this question measure of two sides and and the angle between these sides of a triangle is given.
We have to calculate the measure of third side.
By applying cosine rule in the given triangle.
BC² = AB² + AC² - 2(AB)(AC)cos(A)
BC² = (18)² + (12)² - 2(18)(12)cos(62°)
BC² = 324 + 144 - 202.81
BC² = 265.19
BC = 16.28
BC ≈ 16 units
Therefore, Option C will be the correct option.

Answer:
B: A systematic random sample
Step-by-step explanation:
Systematic sampling is a type of probability sampling in which members of a larger population are chosen at random from a larger population but at a fixed, periodic interval. This interval, also known as the sampling interval, is calculated by dividing the population size by the sample size desired. Despite the fact that the sample population is chosen in advance, systematic sampling is still considered random if the periodic interval is set in advance and the starting point is chosen at random.

There are four points on a line: A, B, C and D, so that AB=1,BC=2,CD=4. Find the length of segment AD. Consider all possibilities and draw a picture for each one of them.
All possible answers for the length of AD are, _, _, _, _, _.
Answer:
7
Step-by-step explanation:
Since it's on a line, we add up all of the numbers. So 1 + 2 + 4 = 7.
Answer:
7, 1, 5, and 3
Step-by-step explanation:
Because you have to consider all possibilities, you will have multiple different-looking number lines. Using the ratios given in the problem, just by playing around with the letters' placements on the number line you can easily find the length of AD.

5/6 + 11/6 = 16/ 6
Step-by-step explanation:
Distance between any Teo labeled tick marks =
(1 - 2/3) / 2 = 1/3 ÷ 2 = 1/3 * 1/2 = 1/6
From the left :
2/3 + 1/6 = 5/6
5/3 + 1/6 = 11/6
5/6 + 11/6 = (5 + 11) / 6 = 16/6
5/6 + 11/6 = 16/ 6

f(n) = 10(1.02)n
Part A: When the scientist concluded his study, the height of the plant was approximately 11.04 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(n) represent? (2 points)
Part C: What is the average rate of change of the function f(n) from n = 1 to n = 5, and what does it represent? (4 points)
Answer:
Step-by-step explanation:
11.04 = 10(1.02)^n
1.104 = 1.02^n
ln 1.104 = ln 1.02^n
ln 1.104 = n ln 1.02
n = ln 1.104/ ln 1.02
n = 4.99630409516
4.99 can be rounded to 5.
So a reasonable domain would be 0 ≤ x < 5
PART B)
f(0) = 10(1.02)^0
f(0) = 10(1)
f(0) = 10
The y-intercept represents the height of the plant when they began the experiment.
f(1) = 10(1.02)^1
f(1) = 10(1.02)
f(1) = 10.2
(1, 10.2)
f(5) = 10(1.02)^5
f(5) = 10(1.1040808)
f(5) = 11.040808
f(1)=10(1.02)^1
f(1)=10.2
Average rate= (fn2-fn1)/(n2-n1)
=11.04-10.2/(5-1)
=0.22
the average rate of change of the function f(n) from n = 1 to n = 5 is 0.22.

A species of animal is discovered on an island. Suppose that the population size of the species can be modeled by the following function, where time t is measured in years. P(t) = 520/1 + 8e-0.3t Find the initial population size of the species and the population size after years.
Answer:
The initial population size is of 58.
The population size of the specie after t years is given by:
[tex]P(t) = \frac{520}{1 + 8e^{-0.3t}[/tex]
Step-by-step explanation:
Population size of the specie:
The population size of the specie after t years is given by:
[tex]P(t) = \frac{520}{1 + 8e^{-0.3t}[/tex]
Initial population size
This is P when [tex]t = 0[/tex], that is, [tex]P(0)[/tex]. So
[tex]P(0) = \frac{520}{1 + 8e^{-0.3*0} = \frac{520}{1+8} = \frac{520}{9} = 57.7[/tex]
Rounding to the nearest number, 58
The initial population size is of 58.
