I keep getting this question wrong. Can someone please give me simple explanation how to solve this
Answers
Step-by-step explanation:
divide the figure into a square and a rectangle
the area of the figure (S) is the sum of the square ( A) and the rectangle (B)
A = 3*3 = 9
B = 7*5 = 35
So S = A+B = 35 +9 =44
Answer:
44cm^2
Step-by-step explanation:
So you can first find the area of the top box by doing 3x3 (square) and than adding the area of the bottom box by doing 7x5 (rectangle).
The way I got 3x3 is because if you look at the bottom the total length is 7. Above that horizontal line is the number 4 and 3. You use the number 3 as it is part of the square.
No the way I got 7x5 is if you look at the right side the full length is 8. In front of that is the vertical line having the number 3. In order to figure out the side length for the bottom part you need to do 8-3. You than get 5 which is your side length for the far-left vertical line.
Now if you do the area of the square + the area of the rectangle you get the full area of the figure:
(3x3) + (7x5)
9 + 35
44

Herschel uses an app on his smartphone to keep track of his daily calories from meals. One day his calories from breakfast were more than his calories from lunch, and his calories from dinner were less than twice his calories from lunch. If his total caloric intake from meals was , determine his calories for each meal.
Answers
Answer:
let the number of calories from lunch be called L. As such, breakfast is then L + 128, and dinner is 2L - 400. We can then sum the three meals and equate it to the total caloric intake, the known value of 1932.
So: 1932 = L + L + 128 + 2L - 400 = 4L - 272.
Lunch = 551
Breakfast = 551 + 128 = 679
Dinner = 2*551 - 400 = 702
Find the value of x. Then find the measure of each labeled angle. x = 37.5; the labeled angles are 77.5º and 102.5º. x = 37.5; the labeled angles are 37.5º and 142.5º. x = 15; both labeled angles are 55º. x = 25; both labeled angles are 65º.
Answers
Answer:
x = 25; both labeled angles are 65º
Step-by-step explanation:
To find the value of x, recall that the angles formed by two parallel lines on the same line are equal if they correspond to each other.
In the figure given above, we have two parallel line given. The angle formed by each parallel line is corresponding to the other. Therefore, both angles formed are equal.
Thus,
(3x - 10)° = (x + 40)°
Solve for x
3x - 10 = x + 40
Subtract x from both sides
3x - 10 - x = x + 40 - x
3x - x - 10 = x - x + 40
2x - 10 = 40
Add 10 to both sides
2x - 10 + 10 = 40 + 10
2x = 50
Divide both sides by 2
2x/2 = 50/2
x = 25
*Plug in the value of x to find the measure of each labelled angles:
(3x - 10)° = 3(25) - 10 = 75 - 10 = 65°
(x + 40)° = 25 + 40 = 65°

In a certain section of Southern California, the distribution of monthly rent for a one-bedroom apartment has a mean of $2,075 and a standard deviation of $300. The distribution of the monthly rent does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 55 one-bedroom apartments and finding the mean to be at least $1,985 per month
Answers
Answer:
Probability is 1
Step-by-step explanation:
We are given;
mean;μ = $2,075
Standard deviation;σ = $300
n = 55
x' = $1,985
Now, we want to find x' to be at least $1,985 which is P(x' > $1,985).
The z-value is calculated from;
z = (x' - μ)/(√σ/n)
Plugging in the relevant values;
z = (1985 - 2075)/(√300/55)
z = -38.536
So, P(x' > $1,985) = P(z > -38.536)
This transforms to;
P(z < 38.536)
Probability from z distribution table is 1

Uncle Louise is at least 1 inch shorter than Miriam, and at least 2 inches taller than Jeffery. Jeffery's height is 64 inches. Miriam is not more than 5 inches taller than Jeffery. Which answer could be Uncle Louise's height? Please answer!!!
Answers
Answer:
67 inches
Step-by-step explanation:
Let's call the height of Louise 'L', the height of Miriam 'M' and the height of Jeffery 'J'.
Then, we can write the following equations and inequations:
[tex]L \leq M - 1[/tex]
[tex]L \geq J + 2[/tex]
[tex]J = 64[/tex]
[tex]M \leq J + 5[/tex]
Substituting J in the second and four inequations, we have:
[tex]L \geq 66[/tex]
[tex]M \leq 69[/tex]
If we assume the maximum value for M, in the first inequation we have that:
[tex]L \leq 68[/tex]
So the height of Uncle Louise is greater than or equal 66, and lesser than or equal 68, so his height could be 67 inches for example.

Step-by-step explanation:
The hypothese is the function is linear. Lets prove it .
If we divide the difference of 2 any function's values by the difference of the corresponding argument's values we will get the same ratio 0.48(for instance 19.210-18.250=0.96 delete be 2-0=2 will get 0.48) .
Lets calculate any other pair of y (function) and x ( argument) :

9x +8 = 15x - 46
Subtract 9x from each side
9x-9x +8 = 15x -9x - 46
8 = 6x - 46
Add 46 to each side
54 = 6x
Divide by 6
54/6 = 6x/6
9 =x
Answer:
D is the answerExplanation:
This is because you have to first make the equations equal to each other. You do this because you can see that the angles are equal to each other meaning that they are the same amount of degrees. So the equation you will have is (9x + 8) = (15x - 46).
9x + 8 = 15x - 46
You can take off the parenthesis.
Subtract 8 from both sides.
This will lead to
9x = 15x - 54
Then you have to subtract 15x from both sides.
This will have a result of
-6x = -54
When you do this you can see that there are 2 negatives. You can cancel these out. So it will look like
6x = 54
Finally, you have to simplify. Divide both sides by 6.
54/6 = 9 6x/6 = x
The final result is
x = 9So, it can be concluded that the answer is the letter D or the number 9.

Convert 9 feet to inches
Answers
Answer: 108 inches
Step-by-step explanation: The answer would be 108 inches because if you multiply the number that coverts a inch into a foot it would be 12 because 12 inches is equivalent to 1 foot. So you know that 1 foot is equal to 12 inches so you multiply the number of feet by 12. You expression is 9 times 12 and after you multiply the two numbers you get 108 inches.
Answer: 108 inches
Step-by-step explanation: To convert 9 feet into inches, we use the conversion factor for feet and inches which is 12 inches = 1 foot.
Next, notice that we're going from a
larger unit, feet, to a smaller unit, inches.
When we go from a larger unit to a smaller unit, we
multiply 9 by the conversion factor, 12 to get 108.
So 9 feet = 108 inches.

The program goes through the following steps when the input is 13
step 1) check to see if the age is less than 2. It is not, so we move on
step 2) check to see if the age is 2 to less than 12. It is not, so we move on
step 3) check to see if the age is 12 to less than 22. We are in the right range, so we execute the print statement "student admission is $8"
After this the program is done. It doesn't check to see if the age is greater than 22 (that only would apply if the other if statements were false).

Answers
Answer:
lateral area =150 square feet
Step-by-step explanation:
lateral area =(perimieter of prism base) times the height of the prism
so, the perimeter of the base is 9 ft*2 + 6 ft*2 which equals 30 ft
then you multiply the perimeter of the base by the height of the prism
so, height of prism =5 ft, so 5 ft times 30 ft =150 feet
therefor, the lateral area of the prism = 150 feet squared

Let U = {D, E, F} be any vector with respect to Basis B
U = D [1 − 3t²] + E [2+t− 5t²] + F[1 + 2t]..............(*)
U = [D+2E+F]+ t[E+2F] + t²[-3D-5E]...................(**)
In Matrix form;

The change of coordinate matrix is therefore,
[tex]M = \left[\begin{array}{ccc}1&2&1\\0&1&2\\-3&-5&0\end{array}\right][/tex]
To find D, E, F in (**) such that U = t²
D + 2E + F = 0.................(1)
E + 2F = 0.........................(2)
-3D -5E = 1........................(3)
Substituting eqn (2) into eqn (1 )
D=3F...................................(4)
Substituting equations (2) and (4) into eqn (3)
-9F+10F=1
F = 1
Put the value of F into equations (2) and (4)
E = -2(1) = -2
D = 3(1) = 3
Substituting the values of D, E, and F into (*)
U = t² = 3 [1 − 3t²] - 2 [2+t− 5t²] + [1 + 2t]
