Answer:
B. a warm coat, because the winters will be cold
Step-by-step explanation:
Continental climates are notable for extreme weather conditions. When it is hot, it is extremely hot and when it is cold, it is extremely cold. Tropical climates on the other hand are known to always have hot weather conditions.
Since Harry is already used to the tropical climate which largely features hot temperatures, we assume that he already has suitable clothing for such weather conditions. So, in addition to that, Harry would need warm clothing for the cold winters which he would experience in the continental climate. So, Harry would need a warm coat because the winter will be cold.

Ifx=-3 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the
equation?
Answer:
D = 0
Step-by-step explanation:
Given
x-intercept = -3
Required
What does the discriminant represent?
The discriminant of a quadratic function can take any 3 values; these are as follows;
When D > 0 When D < 0When D = 0Which translates to
signifies that two different real roots existsignifies that only complex roots existsignifies that the two identical real roots existThe question says that x-intercept = -3 is the only value;
This means that: x = -3 or x = -3
Analyzing the roots
3 and -3 are identical-3 and -3 are realThis means they satisfy condition number 3;
Hence, D = 0
Cameron Indoor Stadium at Duke University is one of the most revered sites in all of college basketball, as well as in all of sports period. Duke’s men’s and women’s basketball programs have attained quite a few wins in the building over the last seventy years. Cameron Indoor Stadium is capable of seating 9,460 people. For each game, the amount of money that the Duke Blue Devils’ athletic program brings in as revenue is a function of the number of people in attendance. If each ticket costs $45.50, find the domain and range of this function.
Answer:
Step-by-step explanation:
The domain of a function is the set of values that satisfies the independent variable while the range of the function is the set of values that satisfies the dependent variable.
Since for each game, the amount of money that the Duke Blue Devils’ athletic program brings in as revenue is a function of the number of people in attendance, then the dependent variable is the amount of money while the independent variable is the number of people. The domain is between 0 and 9460 people. Therefore, the domain of this function is
0 ≤ x ≤ 9460
Where x represents number of people.
For the range, the lowest total sales is 0 × 45.5 = $0
The highest total sales is
9460 × 45.5 = $430430
The range is
0 ≤ y ≤ 430430
Where y represents total sales

What is the area of the triangle below?
Answer:
½bh units if height is known or
A = √S(s-a)+(s-b)+(s-c)units if height is not given. This is most definitely the right answer
Step-by-step explanation:
Hello,
In the question above, we don't have a dimension but we can solve this directly using it's formula and defining the angle
The triangle above is an isosceles triangle.
Isoscele triangles are triangles that have two of its side equal.
The area of a triangle is given as ½ × breadth × height.
The height can easily be calculated using one of it's slant height and it's breadth. This is done using pythagoras theorem. Which is given by
x² = y² + z²
In this case, the area of this triangle is ½b×h.
However, there are cases where by three sides are given known as a, b and c. We can easily use Heron's formula to find the area
A = √S(s-a)+(s-b)+(s-c)
Where s = (a + b + c) / 2
S = perimeter
Fifteen cups of flour are to be stored in containers. Each container holds 2 1/3 cups. How many containers will the flour fill?What fraction of another container will it fill?
Answer:
We will fill 6 containers with 3/7 of another full
Step-by-step explanation:
Take the number of cups of flour and divide by the amount each container will hold
15 ÷ 2 1/3
Change to an improper fraction
15 ÷ ( 3*2+1)/3
15÷ 7/3
Copy dot flip
15 * 3/7
45/7
Change to a mixed number
6*7 = 42 with 3 left over
6 3/7
We will fill 6 containers with 3/7 of another full
Answer:
6 full and 3/7 of container
Step-by-step explanation:
15 cups divided by 2 1/3
(15) /2 1/3 =45/7=6.429 you need 7 containers
6 containers full and 3/7 of container
Consider parallelogram JKLM below.
Use the information given in the figure to find x, m
ZL, and m ZLMK.
Answer:
x = 5
∠L = 114°
∠ LMK = 31°
Step-by-step explanation:
In parallelogram, opposite sides are parallel and equal.
3x = 15
Divide both sides by 3
3x/3 = 15/3
x = 5
In parallelogram, opposite angles are equal
∠L = ∠J
∠L = 114°
In ΔJKM,
∠J + ∠JKM + ∠JMK = 180 {Angle sum property of triangle}
114 + ∠JKM + 35 = 180
149 + ∠JKM =180
∠JKM = 180 - 149
∠JKM = 31°
JK & ML are parallel and KM is transversal
Therefore, ∠ LMK = ∠JKM { oppoiste interior angles are congruent}
∠ LMK = 31°
Answer:
x = 5
∠L = 114°
∠ LMK = 31°
I divided one hole number by another hole number and got 3.125 on my calculator. both my numbers are less than 50 but I'v forgotten what they are. Can you work out what they are?
Answer:
25 and 8
Step-by-step explanation:
a/b = 3.125
a/b = 3125/1000
make it simple (divide by 25)
a/b = 125/40
ah, can be more simple (divide by 5)
a/b = 25/8
see 25 + 8 is less than 50
Step-by-step explanation:
1.25/8=3.125
50/16=3.125
but it tells that both two numbers are less than 50 then,the numbers are 25 and 8

Answer:
r = 5
I just turned it in it was correct
Step-by-step explanation:
please mark brainliest
Answer:
7 = 2 + r
Step-by-step explanation:
So since we know the hanger is balanced, we can determine that r = the amt. of the other side - 2. =>
We can count the amt. of "1" on the side of the hanger with only 1 --> to get 7 "1" which is 7(1) = 7.
The other side with "r" has 2 "1" thus --> 2(1) = 2
So, 7 = 2 + r is our equation and if we were to solve for r, => r = 5

5 times a is addedto b
thesum of number x and y is multiplyed by 3
Answer:
x+y=5a
5a is added to b which is the sum of x and y multiplied by 3. That is, b=x+y×3=5a×3=15a
Since, 5a is added to b= 5a+15a=20a,

Simplify 12^16 over 12^4
Answer: 12¹²
Step-by-step Explanation: The 12's in this problem are bases so as you apply the quotient rule, subtract the exponents but leave the base alone to get 12¹².
Answer:
12^(12)
Step-by-step explanation:
(12^16)/(12^4)
Apply the law of exponents where a^b/a^c = a^(b - c)
12^(16 - 4)
= 12^(12)
translate into an algebraic expression: 120 is increased by d % and increased by 25% . What is the result ?
The result is number [tex]r[/tex] where:

4/5 of a number is 32
Answer:
x = 40
Step-by-step explanation:
Step 1: Write out an equation
4/5(x) = 32
Step 2: Solve by dividing both sides by 4/5
x = 32/(4/5)
Use KCF (Keep Change Flip) if you do not have a calc.
x = 40
Answer:
The answer is 40
Step-by-step explanation:
32 times 5 is 160
then: 160 divided by 4 is 40.
check the answer: 4/5 of 40 is 32
because 40 divided by 5 is 8 and then times 8 by 4, so the answer would be 40.

what is the 10th nTh term for this sequence: 1,3,5,7........(it doesnt seem to work and i think i got it wrong so if you can help me) rule is 2n-1
the 10 th term for the sequence 1,3,5,7..... is 19
Step-by-step explanation:
n = 1; 1st = 2*1–1=1;
n= 2; 2nd =2*2–1=3;
n =3; 3rd =2*3–1=5;
n=4; 4th =2*4–1=7;
n=5; 5th =2*5–1=9;
n=6; 6th =2*6–1=11;
n=7; 7th = 2*7-1= 13
n= 8; 8th = 2*8-1 =15
n = 9; 9th = 2*9-1 = 17
n= 10; 10th = 2*10-1 =19

PLS HELP ASAP Given the following probabilities, for what P(B) are events A and B independent? P(A)=23 P(A and B)=13
I'm assuming you meant to say
P(A) = 2/3
P(A and B) = 1/3
If that is the case, then A and B are independent if and only if the following equation is true
P(A and B) = P(A)*P(B)
So we multiply P(A) and P(B) to get the value of P(A and B). We don't know what P(B) is, but we can use algebra to find it
-------------------------
P(A and B) = P(A)*P(B)
P(A)*P(B) = P(A and B)
(2/3)*P(B) = 1/3
P(B) = (1/3)*(3/2) .... multiply both sides by the reciprocal of 2/3
P(B) = (1*3)/(3*2)
P(B) = 1/2 is the answer------------------------
If P(B) = 1/2, then
P(A and B) = P(A)*P(B)
P(A and B) = (2/3)*(1/2)
P(A and B) = (2*1)/(3*2)
P(A and B) = 1/3
Which is the given probability for both events happening. This confirms we have the correct P(B) value.

1/2x=-1/2x+5 please help please I really need help for is x
Answer:
x = 4 2/7
Step-by-step explanation:
2/3 x= -1/2x+5
Add 1/2 to each side
2/3 x 1/2 x = -1/2x+1/2x+5
2/3 x +1/2x =5
Get a common denominator
2/3x *2/2 + 1/2 *3/3 = 5
4/6x + 3/6x = 5
7/6x = 5
Multiply each side by 6/7 to isolate x
6/7 *7/6x = 5 *6/7
x = 30/7
Change to a mixed number
x = 28/7 + 2/7
x = 4 2/7
