Answer:
The least possible number is 148---------------------------------------------------
Let the number be N.
If N is divided by 5 the remainder is 3:
N = 5k + 3,Similarly:
N = 6p + 4,N = 7q + 1.We can observe N + 2 is divisible by both 5 and 6, then it can be represented as:
N + 2 = 30m,so
30m = 7q + 1 + 2 or30m - 3 = 7qThe left side is divisible by 3, then q = 3t:
30m - 3 = 7*3t10m - 1 = 7tThe least m and t would be m = 5 and t = 7.
Then:
N + 2 = 30*5 = 150 ⇒ N = 148 is the least possible number.Proof:
148/5 = 29 (rem 3)148/6 = 24 (rem 4)148/7 = 21 (rem 1)A train covers a dictance of 820KM in 8 hours. How much distance will ir cover in 1 hour?

Rose has less than $30 to spend on decorations for the school dance. She has already spent $5. Which number line shows how much money she could still spend on decorations
The correct answer is number line A. Number Line A shows that Rose has $25 remaining to spend on decorations. The number line shows that she has already spent $5, as indicated by the arrow pointing from 0 to 5.
What is Number Line?Number line is the visual representation of numbers on a straight line. These are often used to represent linear equations, as well as to learn basic mathematical concepts such as addition, subtraction, multiplication, and division.
The number line shows that she has a total of $30 available for decorations, as indicated by the arrow pointing from 0 to 30. Between the two arrows, it is clear that Rose has $25 remaining to spend on decorations.
Number Line B does not accurately represent Rose’s situation because the arrow pointing from 0 to 20 does not indicate that Rose has already spent $5. Number Line C does not accurately represent Rose’s situation because the arrow pointing from 0 to 25 does not indicate that Rose has a total of $30 available to spend.
To solve this problem, Rose needs to identify the total amount of money she has available to spend on decorations and the amount of money she has already spent. Once she has identified these two values, she can use a number line to represent her situation.

Parallel lines e and f are cut by transversal b.e=(2x+10) f=(3x-15)What is the value of x?A.1B.5C.25 D. 37
The value of x can be determined by solving the equations for e and f. To solve, subtract 3x from both sides of equation f, then add 10 to both sides of equation e. This will result in the equation -5=25, which when solved for x will result in a value of x=5.
In order to determine the value of x in the given problem, you must first solve the equations for e and f. Starting with equation e, add 10 to both sides of the equation to get 2x=20. Then, look to equation f and subtract 3x from both sides of the equation to get -15=3x. When both equations are combined, you get -5=25. Solving this equation for x will result in a value of x=5. Therefore, the value of x in this problem is 5. To summarize, when given two equations containing the same variable, you must solve them by adding or subtracting the same amount to both equations. This will result in an equation which can be solved for the desired variable. In this case, the value of x is 5.

create a conversion factor between grains of sand and mass based on the data you have collected. use this conversion factor to determine the grains of sand in your 50-ml beaker.
There are 0.001 grains of sand in your 50-ml beaker.
To create a conversion factor between grains of sand and mass, you need to determine the mass of one grain of sand. Once you have that information, you can create a conversion factor by dividing the mass of one grain of sand by the mass of the 50-ml beaker. This will give you the number of grains of sand per unit mass.
For example, if one grain of sand has a mass of 0.001 grams and the 50-ml beaker has a mass of 50 grams, the conversion factor would be 0.001 grams/grain of sand ÷ 50 grams = 0.00002 grains of sand/gram.
To determine the grains of sand in your 50-ml beaker, you can multiply the conversion factor by the mass of the beaker. In this case, 0.00002 grains of sand/gram x 50 grams = 0.001 grains of sand.
Therefore, there are 0.001 grains of sand in your 50-ml beaker.

Determine if the following are True or False. If it is true, give a justification. If it's false, give an example showing why the statement is not always true.If v1,v2,v3,v4,v5 are in R5 and {v1,v2,v3,v4} is linearly dependent, then {v1,v2,v3,v4,v5} is also linearly dependent.If v1 and v2 are in R4 and v2 is not a scalar multiple of v1, then {v1,v2} is linearly independent.Must give justification/example for full points.\
{v1, v2, v3, v4, v5} is also linearly dependent. Therefore, the first statement is True. {v1, v2} is linearly independent. Therefore, the second statement is also True.
If {v1, v2, v3, v4} is linearly dependent, then there exists a non-zero scalar, say a1, a2, a3, and a4, such that a1v1 + a2v2 + a3v3 + a4v4 = 0. Now, if we add v5 to the set, we can simply take a5 = 0, and the equation a1v1 + a2v2 + a3v3 + a4v4 + a5v5 = 0 still holds. Therefore, {v1, v2, v3, v4, v5} is also linearly dependent.
For the second statement if v2 is not a scalar multiple of v1, then there are no scalars a1 and a2 such that a1v1 + a2v2 = 0, unless both a1 and a2 are zero. This means that {v1, v2} is linearly independent. A justification for this can be seen by considering the equation a1v1 + a2v2 = 0. If v2 is not a scalar multiple of v1, then the only solution to this equation is a1 = a2 = 0, which means that {v1, v2} is linearly independent.

One of the legs of a right triangle measures 1 cm and the other leg measures 7 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Using the Pythagorean Theorem ( a^2 + b^2 = c^2, c is the length of the hypotenuse) and substituting values in, you get 1^2 + 7^2 = c^2. That can be simplified to the square root of 50 = c. The square root of 50 is not a whole number, so rounded to the nearest tenth it would be 7.1.
an event that increases the probability that a response will be repeated is called _____.
The term that describes an event that increases the likelihood of a response being repeated is known as reinforcement.
Reinforcement can be defined as any consequence that strengthens or increases the probability of a behavior occurring again in the future. This can include positive reinforcement, which involves adding a desirable consequence after a behavior, or negative reinforcement, which involves removing an aversive consequence after a behavior. Both types of reinforcement have been shown to be effective in increasing the likelihood of a behavior being repeated.
Overall, understanding the concept of reinforcement is essential in the field of psychology, particularly in the areas of behaviorism and behavior modification. By providing positive consequences after desired behaviors, individuals can be motivated to continue engaging in those behaviors, which can lead to long-term positive changes. Reinforcement can also be used to shape new behaviors or replace unwanted behaviors with more desirable ones.

Answer:
a. 24
b. 864
Step-by-step explanation:

The contrapositive of p → q is "if 3x + 7 ≠ -5, then 4x + 12 ≠ -4."
Given p: 3x + 7 = -5 and q: 4x + 12 = -4, the original implication is p → q.
As we know that the contrapositive of an implication statement flips the hypothesis and the conclusion of the original statement and negates them.
To find the contrapositive, we need to flip the hypothesis and conclusion and negate them.
The hypothesis of p is "3x + 7 = -5" and its negation is "3x + 7 ≠ -5."
The conclusion of q is "4x + 12 = -4" and its negation is "4x + 12 ≠ -4."

Answer:
h = 61.83 feet
Step-by-step explanation:
length of string from Hector to kite = c = 86 feet.
and 4 feet off the ground.
angle A = 42° 15' 30"
req'd: how high is the kite?
angle A = 42° + 15' (1° / 60') + 30"(1° / 3600'')
angle A = 42.26
to get the side a (height of kite) 4 feet above ground: use Sin(A) = opp / hyp
Sin(A) = a / c
Sin(42.26) = a / 86
a = Sin(42.26) * 86
a = 57.83 feet

£200 is invested for 10 years at 9 compound interest per annum
After 10 years at 9% compound interest per annum, The amount will be £393.57.
The amount of money you will have after 10 years can be calculated using the formula for compound interest:
\(A = P * (1 + r/n)^{nt}\)
where:
A is the final amount,
P is the initial amount (principal),
r is the interest rate as a decimal,
n is the number of times the interest is compounded per year,
t is the number of years the money is invested.
In this case:
P = £200
r = 9% = 0.09
n = 1 (because interest is compounded annually)
t = 10
So, plugging in the values, we get:
\(A = 200 * (1 + 0.09/1)^{1 * 10)} = 200 * (1.09)^{10}\)
\(A = 200 * 1.96787 = 393.57\)
