Answer:
652 ft²Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
Adam is 12 years older than his sister Liz. Four years ago Adam was 4 times older than his sister. How old is each now?
His sister is 8 and he is 20.
let's say z represents liz. we can make an equation where z+12=4z.
Solve for that and z is equal to 4. Now that was 4 years ago. She should be 8 now?
I hope this is correct because my brain isn't doing so well today.
Answer:
Adam is 20 years old and Liz is 8 years old.
Step-by-step explanation:
Let present age of Adam = x years
Let present age of Liz = y years
Now we will make the equations.
x = y + 12 -------------(1)
For second equation
( x-4) = (y-4) × 4
x-4 = 4y - 16
x = 4y + 4 - 16
x = 4y - 12 -----------------(2)
By substitution method, we substitute the value of x from equations (1) to equation (2).
y + 12 = 4y - 12
y - 4y + 12 = -12
-3y = -12 -12
3y = 24
y = 8
Now we put the value of y in equation (1)
x = 8 + 12 = 20
Therefore, Adam is 20 years old and Liz is 8 years old.

It takes 10 workers 24 hours to do a job. How does y vary with x − directly or inversely? What is the coefficient of variation?
The total cost y varies directly with the number of hours x needed to complete a job, with a direct variation coefficient of 100.
Explanation:When analyzing the variation between two variables, specifically how y varies with x, we consider whether the relationship is direct or inverse. In the scenario provided, where it takes 10 workers 24 hours to do a job, if we let x represent the number of hours it takes to get the job done and y represent the total cost to the customer, we can establish that as the number of hours increases, the total cost also increases, assuming workers are paid by the hour. This suggests a direct variation.
Given that widget workers receive $10 per hour, the cost y to the customer for x hours of work would be 10 workers × $10 per hour × x hours. So, y = 10 × 10 × x = 100x. Hence, the relationship between y and x is directly proportional with a coefficient of variation of 100.
What is the experimental probability
Answer:
choice A is correct
Step-by-step explanation:
For a fair coin, the theoretical probability of obtaining heads or tails is 50%
Increasing the number of trials has the effect of making the experimental probability and theoretical probability equal
Answer:
It's the first option.
Step-by-step explanation:
Assuming it is a fair coin you would expect the experimental probability to get closer to 50%.
50% is the theoretical probability for a fair coin because there are 2 equally possible outcomes ,heads or tails.

Calculate cos 0 to two decimal places
We can use the law of cosines as follows:
[tex]7^2 = 8^2+10^2-2\cdot 8 \cdot 10 \cdot \cos(\theta)[/tex]
We can rewrite this equation as
[tex]49 = 164-160 \cdot \cos(\theta) \iff 160 \cdot \cos(\theta) = 115 \iff \cos(\theta)=\dfrac{115}{160}\approx 0.72[/tex]
For this case we have by definition of the Cosines Law that:
[tex]7 ^ 2 = 10 ^ 2 + 8 ^ 2-2 (10) (8) [/tex]* cosΘ
[tex]49 = 100 + 64-160[/tex]cosΘ
[tex]49 = 164-160[/tex]cosΘ
[tex]49-164 = -160[/tex]cosΘ
[tex]-115 = -160[/tex]cosΘ
[tex]115 = 160[/tex]cosΘ
cosΘ= [tex]\frac {115} {160} = 0.71875[/tex]

You own 5 pairs of jeans and want to take 2 of them with you on vacation. In how many ways can you choose 2 pairs of jeans?
A. 10 ways
B. 15 ways
C. 4 ways
D. 20 ways
is the answer D?
the answer would be D
The number of ways to choose 2 pairs of jeans from 5 is calculated using combinations, resulting in 10 different ways, corresponding to option A.
To determine the number of ways to choose 2 pairs of jeans from 5, we need to use the combination formula, which is defined as C(n, k) = n! / (k! * (n-k)!), where 'n' is the total number of items to choose from, 'k' is the number of items to choose, and '!' denotes factorial.
In this case, n = 5 and k = 2. Therefore, the calculation becomes:
C(5, 2) = 5! / (2! * (5 - 2)!)
= (5 * 4 * 3 * 2 * 1) / ((2 * 1) * (3 * 2 * 1))
= (5 * 4) / (2 * 1)
= 20 / 2
= 10 ways.
So, there are 10 ways to choose 2 pairs of jeans from 5 pairs, which corresponds to option A.
a scale model is made of a plane whose length is 114ft and whose wingspan is 95ft if the length of the model is 31 inches, find the wingsoan of the scale model to the nearest tenth of an inch.
Answer:
25.8
Step-by-step explanation:
114 ft ---> 31 inches
114 ft = 1368 inches
31/1368=0.02266081871 inch scale model
95 feet = 1140 inches, so 1140 * the scale factor of 0.02266081871= 25.83333..
This means, to the nearest tenth inch, the wingspan of the scale model is 25.8
The wingspan of the scale model is approximately 25.8 inches when calculated using the scale factor based on the model's length and the actual length of the plane, both in inches.
To find the wingspan of the scale model, we need to set up a proportion based on the scale between the actual size and the model size of the plane. First, we will find the scale factor by comparing the actual length of the plane to the length of the model in the same units:
Actual length of plane: 114 ft
Model length of plane: 31 inches
We must convert the actual length into inches because the model is measured in inches (1 foot = 12 inches) 114 feet × 12 inches/foot = 1368 inches
The scale factor is the ratio of the model length to the actual length.
Scale Factor = Model Length / Actual Length in inches = 31 inches / 1368 inches
Now, to find the wing span of the model, we use the same scale factor:
Actual wingspan of plane: 95 ft
95 ft × 12 inches/ft = 1140 inches (Actual wingspan in inches)
Model Wingspan = Actual Wingspan in inches × Scale Factor
= 1140 inches × (31 inches / 1368 inches)
We calculate this to get the model's wingspan in inches and round it to the nearest tenth of an inch:
Model Wingspan = (1140 × 31) / 1368 ≈ 25.8 inches
Therefore, the wingspan of the scale model is approximately 25.8 inches when rounded to the nearest tenth.

[tex]A = (5x+3)(x+6) - (4x^2 + 26x + 15)[/tex]
[tex] = 5x^2+33x+18 - 4x^2 -26x - 15[/tex]
[tex] =x^2+7x+3[/tex]
Answer: Choice A
Answer with Step-by-step explanation:
A window frame has a length of (5x + 3) inches and a width of (x + 6) inches.
Area of window frame=(5x+3)(x+6)
= 5x(x+6)+3(x+6)
= 5x²+30x+3x+18
= (5x²+33x+18) square inches
area of the glass in the window is (4x² + 26x + 15) square inches.
Area of trim around the glass=Area of window frame-Area of glass
= 5x²+33x+18-(4x²+26x+15)
=5x²-4x²+33x-26x+18-15
=(x²+7x+3) square inches
Hence, Correct option is:

line q and line M are cut by transversal lines J&K the lines and the measures of some of the angles created by the intersections of the lines are shown in the diagram below. What is the measure of angle 5?
The angle of 110° and the angle labelled as 1 form 180°, so we have
[tex]<1> = 180-110=70[/tex]
The same holds for the angle labelled 2 and the 115° angle:
[tex]<2> = 180-115=65[/tex]
Angle 1, 2 and 7 are the interior angles of a triangle, so they sum to 180. We can deduce
[tex]<7> = 180-70-65=45[/tex]
Angles 5 and 7 are corresponding angles, so they have the same measure.
Give an example of a function with a domain of (-infinity,0)
You may consider a function with domain [tex](0,\infty)[/tex] and switch [tex]x\mapsto -x[/tex]
For example, we know that

[tex]y=\log(-x)[/tex]
can also be evaluated only for positive values of the argument, i.e.
[tex]-x>0 \iff x<0 \iff x \in (0,\infty)[/tex]
To give another example, you may consider a function with domain [tex][0,\infty)[/tex], consider its inverse to remove 0 from the domain, and finally switch again [tex]x\mapsto -x[/tex]:
[tex]\sqrt{x} \implies D = [0,\infty)\\\dfrac{1}{\sqrt{x}} \implies D = (0,\infty)\\ \dfrac{1}{\sqrt{-x}} \implies D = (-\infty,0)[/tex]
Six times Jason's collection of books and one-third of Nathan's collection add up to 134 books. One-third of Jason's collection and Nathan's entire collection add up to 31 books.
The number of books in Jason's collection is? , and the number of books in Nathan's collection is ?
Answer:
Jason's collection: 21 books.
Nathan's collection 24 books.
Step-by-step explanation:
Let number of books owned by Jason be j books and that for Nathan be n books.
So we have the system:
6j + 1/3 n = 134.........(1)
1/3j + n = 31................(2)
Multiply the first equation by -3. We get:
-18j - n = -402............(3)
Adding (2) + (3):
-53/3 j = -371
j = -371 * 3 / -53
j = 21.
Now substitute j = 21 in equation (2):
1/3(21) + n = 31
n = 31 - 7 = 24
n = 24.
