Answer:
26
Step-by-step explanation:
2 squares + 3 circles = 31. So, the sum of the squares is divisible by two, and the sum of the circles is divisible by 3. Then, I used trial and error to figure out that the square's value is five, and the circle's value is seven. 5 + 7 + 7 = 19. 27 - 19 = 8. The triangle's value is eight. 5 + 7 + 12 = 24. It works. 15 + 7 + 4 = 26

A center-pivot sprinkler system operated by Colorado Land & Agriculture, Inc., is used to water the alfalfa in a circular field. The circumference of the field is 2 miles. As the sprinkler travels in an arc around the field, sprinkler nozzles get clogged and must be cleaned. The distance around the circumference of the field from the starting point to the point when a nozzle becomes clogged is the value of a random variable X that is uniformly distributed over the 2-mile circumference of the field. As a part of a simulation comparing farm maintenance policies, an input is the point at which sprinklers become clogged. If a random number 0.724 is generated, at what distance from the starting point would we simulate that a nozzle becomes clogged? Give your answer to 3 decimal places.
Answer:
The answer is "1.448 miles".
Step-by-step explanation:
X= The distance to both the nozzle clogged from of the starting point.
X [tex]\sim[/tex] Uniform(0,2) miles.
They are simulating the random number Y=0.724, and the Y has both a distribution uniform(0,1). Therefore 2Y is distributed evenly (0.2). And They model the clogging of its nozzle at 2Y=1.448 miles

Answer:
BCD = 90˚
ABD = 16˚
CBE = 74˚
ADE = 74˚
AEB = 148˚
DEA = 32˚
Step-by-step explanation:
BCD: I suppose that’s a rectangle, and all rectangles have four right (90˚) angles.
ABD: alternate interior angles are congruent, so ABD is congruent to BDC (16˚).
CBE: Complementary angles add up to 90˚, so just subtract ABD (16˚) from 90˚ to equal 74˚.
ADE: Same this as CBE for same reason.
AEB: You need to find DEC first for this. To find DEC, add BDC and ACD together to get 32˚, then subtract that from 180˚ to find the answer (148˚). This is because all triangles have a 3 interior angle measure sum of 180˚. (And vertical angles are congruent).
DEA: Subtract AEB from 180˚ because they’re supplementary angles.

Write an equivalent expression for (m + 4n) - 2.5m
Answer:
-1.5m + 4n is the equivalent expression
Step-by-step explanation:
To find the equivalent expression, we combine the like terms.
We are given the following expression:
m + 4n - 2.5m
Combining the like terms:
m - 2.5m + 4n
-1.5m + 4n is the equivalent expression
What is the product of (-3x2/3) and (4x3/4)?
Answer: - 1/x or [tex]-\frac{1}{x}[/tex]
Step-by-step explanation:
(-3x^2 /3 ) * (4x^3 / 4)
=> - (3x^3 / 4) * (4x^3 / 3)
=> - (x^2 * 4) / 4x^3
=> - (x^2 / x^3)
=> - 1/x or [tex]-\frac{1}{x}[/tex]
The product of the two numbers will be -6.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two numbers are (-3x2/3) and (4x3/4).
To find the product of (-3 * 2/3) and (4 * 3/4), we first need to simplify each expression:
(-3 x 2/3) = -2
(4 x 3/4) = 3
Next, we multiply the two simplified expressions:
-2 x 3 = -6
So, the product of (-3 * 2/3) and (4 * 3/4) is -6.

Maggie wants to buy a new energyefficient refrigerator. Her old refrigerator uses about 1200 kWh per year,while the new one would use about 400 kWh per year. Approximately how much money would Maggie saveper year if she buys the new refrigerator?
Answer:
800 Kwh
Step-by-step explanation:
To solve this problem, we need to find the difference in energy saved and then multiply by the cost of 1kWh of electricity
How much did Maggie save?Let's first of all calculate the the difference in energy saved
Data;
old refrigerator = 1200kWhnew refrigerator = 400kWh[tex]1200 - 400 = 800kWh[/tex]
Maggie would've saved 800kWh in one year.
But since we were not given a standard cost of electricity, we would assume that 1kWh will cost $1.
So, to determine how much she must've saved, we simply multiply $1 by 800kWh
[tex]1 * 800 = $800[/tex]
Using our assumptions, she would've saved $800 in one year.

cut a 60 cm ribbon into such that one part is one third of the other half
Answer:
15cm and 45cm
Step-by-step explanation:
If one part is one third of the other, then the long one is three times as long as the short one.
If the short one has length x
x + 3x = 60cm
4x = 60cm
x = 15cm
So short one is 15cm and the long one is 3*15cm = 45cm

Help
Answer:
10
Step-by-step explanation:
I simply divided 140/14 and got 10! Hope this helps :)
The 140 percentage of the number 10 is 14
Given data ,
To find the number that is 140% of another number, we can set up the equation:
140% of x = 14
So , 140 percentage of the number x = 14
To solve for x, we need to convert 140% to its decimal form, which is 1.40:
1.40 * x = 14
Now we can solve for x by dividing both sides of the equation by 1.40:
x = 14 / 1.40
Dividing 14 by 1.40 gives us:
On simplifying , we get
x = 10
Therefore , the value of x = 10
Hence , 140 percentage of 10 is equal to 14
