"What is a common multiple for 7 and 3?"
In this problem it's easy, all you have to do is guess and check.
A: A doesn't work. 7 is not a factor of 18.
B: B works! Both 3 and 7 are factors of 21.
C: C doesn't work. 7 is not a factor of 3.
D: D doesn't work. Neither are a factor of 4.
They only leave us with one solution, B.

find the value of x in the triangle below
Answer:
87 degrees
Step-by-step explanation:
the three angles of a triangle add up to one hundred eighty degrees.
1. Add the degrees of the known angles together
56 + 37 = 93
2. Since a triangle adds up to one hundred eighty degrees, you would subtract your known degrees from the total
180 - 93 = 87
What is the approximate area of
the circle? Use 3.14 for T.
25 in.
A. 78 square inches
B. 157 square inches
C. 491 square inches
D. 1,963 square inches
Answer:
D. 1,963 square inches
Step-by-step explanation:
Using the formula of the area of the circle A= [tex]\pi[/tex][tex]r^{2}[/tex] and assuming that the radius is 25 inches.
Then,
A = [tex]\pi[/tex](25 inches)^2
A = (3.14)(25inches)^2
A = 1,963 square inches
However, you did not state that r = 25 inches, so this might not be correct, but good luck and I hope this helps a little!

determine if parallel y = X X + y = -2
Answer: they are not
Step-by-step explanation:
y=x has a slope of 1 because the m value is 1.
x+y=-2 has a slope of -1 because when we subtract x from both sides, we get that y=-x-2 and the m value is -1

Find the area of the
regular figure below:
A) 160.5 km2
B) 166.2 km2
C) 173.8 km2
D) 182.4 km2
E) 189.1 km2
explain pls
Answer:
Option C : 173.8 km² is the correct answer.
Step-by-step explanation:
Given that:
Side length = 6 kilometers
A shape with 8 sides is called an octagon, therefore, the given figure is an octagon.
Area of octagon is given by;
Area = [tex]2(1+\sqrt{2})a^2[/tex]
Putting a=6
Area = [tex]2(1+\sqrt{2})(6)^2[/tex]
Area = [tex](2+2\sqrt{2})(36)[/tex]
Area = 173.82
Rounding off to one decimal place
Area = 173.8 km²
Hence,
Option C : 173.8 km² is the correct answer.

please help me answer this
Answer:
10.77
Step-by-step explanation:
by using Pythagoras theorem we can find the distance between the points,
so...
distance between the points, which is the hypotenuse will be xy
difference between the y coordinates will be dy
difference between the x coordinates will be dx
according to pythagoras theorem,
[tex]xy^{2} = dx^{2} + dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77[/tex]
A board is 48 in long. It must be divided into 4 pieces of equal length, and each cut will cause a waste of 3/16 in. How long will each piece be after the cuts are made?
Answer:
12 pieces
Step-by-step explanation:
Total length of the board = 48 in
It must be divided into 4 pieces of equal length
This means, there will be 3 cut to have 4 pieces
Each cut will cause a waste of 3/16 in.
Total waste = 3 cut × 3/16 in
= (3*3)/16
= 9/16 in
Length of board remaining = Total length of the board - Total waste
= 48 - 9/16
= (768-9)/16
= 759/16 in
How long will each piece be after the cuts are made?
Length of each piece after the cut = Length of board remaining / 4
= 759/16 ÷ 4
= 759/16 × 1/4
= 759/64
= 11.859375
Approximately 12 pieces to the nearest whole number
The seventh grade class is putting on a talent show to raise money for a class trip. It costs $500 to rent the banquet hall they are planning on using. If they charge $15 per ticket, how many tickets do they need to sell in order to raise at least $1000? Part A The variable in this problem will represent the number of Part B Choose the correct inequality to represent the story problem
Answer:
Part A; 15x
Step-by-step explanation:
Part A; 15(67)
= $1005
Part B; ??
The number of tickets to be sold if, The cost of the banquet hall is $500, The cost per ticket is $15, the Total money to be raised is $1000, is 67, and the equation is given by 1000 = 15x.
What is the equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
In other terms, it is a mathematical statement stating that "this is equivalent to that."
Given:
The cost of the banquet hall = $500,
The cost per ticket = $15,
Total money to be raised = $1000
Write the equation of the number of tickets as shown below,
1000 = 15x
Here, x is the number of tickets,
x = 1000 / 15
x = 66.67 or 67

After examining daily receipts over the past year, it was found that the green parrot italian restaurant has been grossing over $2200 a day for about 85% of it's business days.
Complete question is;
After examining daily receipts over the past year, it was found that the green parrot italian restaurant has been grossing over $2200 a day for about 85% of it's business days. Using this as a reasonably accurate measure, find the probability that the green parrot will gross over $2200:
A. At least 5 of the next 7 business days.
B. at least 5 of the next 10 business days.
C. less than 3 of the next 5 business days.
d. Exactly 7 of the next 10 business days
e. At least 1 of the next 5 business days.
Answer:
A) P(X ≥ 5) = 0.9262
B) P(X ≥ 5) = 0.9986
C) P(X ≤ 2) = 0.0266
D) P(X = 7) = 0.1298
E) P(X ≥ 1) = 0.9999
Step-by-step explanation:
This is a binomial probability distribution problem and as such we will use the formula;
P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)
A. At least 5 of the next 7 business days will be;
P (X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7)
P(X = 5) = C(7, 5) × 0.85^(5) × (1 - 0.85)^(7 - 5)
P(X = 5) = 0.20965
P(X = 6) = C(7, 6) × 0.85^(6) × (1 - 0.85)^(7 - 6)
P(X = 6) = 0.396
P(X = 7) = C(7, 7) × 0.85^(7) × (1 - 0.85)^(7 - 7)
P(X = 7) = 0.320577
Thus;
P(X ≥ 5) = 0.20965 + 0.396 + 0.320577
P(X ≥ 5) = 0.9262
B. Probability of at least 5 of the next 10 business days will be;
P(X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)
From online binomial calculator attached, we can see that the answer is;
P(X ≥ 5) = 0.9986
C. Probability of less than 3 of the next 5 business days will be;
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
From online binomial calculator attached, we can see that the answer is;
P(X ≤ 2) = 0.0266
D. Probability of exactly 7 of the next 10 business days will be;
P(X = 7) = C(10, 7) × 0.85^(7) × (1 - 0.85)^(10 - 7)
P(X = 7) = 0.1298
e. Probability of at least 1 of the next 5 business days will be;
P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)
From third image attached using online binomial calculator, we have;
P(X ≥ 1) = 0.9999
