Jack chooses two numbers between 50 and 150
The two numbers have a Lowest Common Multiple (LCM) of 420
They have a Highest Common Factor (HCF) of 28
Work out what the two numbers are.
Answer:
84 and 140
Step-by-step explanation:
Jack chooses two numbers between 50 and 150
The two numbers have a Lowest Common Multiple (LCM) of 420
Factors of 420 between 50 to 150
= 60, 70, 84, 105, 140
We are also told that:
They have a Highest Common Factor (HCF) of 28
Hence, we find out of the factors above, which numbers can be divided by 28 without having any remainder.
60/28 = 2.1428571429
70/28 = 2.5
84/28 = 3
105/28 = 3.75
140/28 = 5
Therefore, the two numbers are
84 and 140

Find the equation of a line that passes through the points (-1,3) and (3,-5).
Leave your answer in the form y = mx + c
Please help me I need to know in the next 10 mins
Answer:
i'm pretty sure that it's y=-2x+1
Step-by-step explanation:
first we solve for the slope of the line:
we have the points (-1,3) and (3,-5). So we write an equation like so:
3 - -5
-1 - 3
3/-1 - -5/3. solving that, you get 8/-4, and 8 divided by -4 is -2, so thats our slope.
now all we've got to do is get the y intercept. the way i found it was i graphed the line, put a dot on the points that we have ( (-1,3) and (3,-5) ) and you should
get 1 as the point on the y axis. again, i myself am not a pro or anything so if its not the correct answer i am so sorry. <3

Answer:
17.8 km80.4 mStep-by-step explanation:
The first attachment shows the sort of geometry involved. The line of sight from the top of the lighthouse makes a tangent with the earth's surface at the horizon (neglecting optical effects due to the atmosphere).
The hypotenuse of the relevant triangle is (r+h), and the angle is adjacent to the radius, r. Then the cosine relation applies:
Cos = Adjacent/Hypotenuse
cos(α) = r/(r+h)
We note that the radius is in km, and the length h is given in meters, so we need to do a conversion to put the numbers in this formula. We don't care so much about the angle itself, but we need its value to find the length of the arc along the earth's surface. That is ...
s = r·α
so, the distance of interest is found from ...
cos(α) = 6367/(6367 +0.025)
r·α = 6367·arccos(6367/6367.025) ≈ 17.84 . . . km
The horizon is about 17.8 km from the observer.
__
The second problem requires we find the height value that makes the distance 32 km.
32 = r·α = 6367·arccos(6367/(6367 +h))
Dividing by the earth's radius and taking the cosine, we have ...
cos(32/6367) = 6367/(6367 +h)
h = 6367 -6367/cos(32/6367) ≈ 6367.0804 -6367 = 0.0804 . . . km
The cliffs must be about 80.4 meters high for it to be possible to see that distance.

Find the cost of 4.8 kilograms of potatoes at the price of $0.75 a
kilogram?
Answer: $3.60
Step-by-step explanation:
If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.
4.8 x 0.75 = 3.6.
Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!

What is the area of the following circle?
Answer:
78.53
Step-by-step explanation:
[tex]\pi[/tex] x [tex]5^{2}[/tex]
Answer:
78.5
Step-by-step explanation:
The formula for the area of a circle is A=πr^2. The radius, (r) is half of the diameter. The diameter of this circle is 10 in, so the radius is 5 in. Plug 5 into the formula A=πr^2 to get A=π5^2. Square 5 to get 25 and plug it back in the formula to have A=25π. Multiply pi (π, 3.14) by 25 to get 78.5.

The number of peach trees in the orchard is directly proportional to
the number of apple trees. When Farmer Bob planted 40 peach
trees, he planted 120 apple trees. Everything was killed in the
drought and he's starting anew. How many apple trees will he
need to plant if he plants 500 peach trees?
Answer:
there was a difference between the 40 and 120 which was 80 so if there are 500 peach trees he would need to plant 580 because you add the difference to the total. The answer is 580 apple trees

Colton owns a food truck that sells tacos and burritos. He only has enough supplies to make 120 tacos or burritos. He sells each taco for $3.75 and each burrito for $6. Colton must sell at least $540 worth of tacos and burritos each day. If xx represents the number of tacos sold and yy represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
Inequality 1) y≤120−x; shade down
Inequality 2) y≥90−0.625x; shade up
Possible solution: (10,100)
*Colton could sell 10 tacos and 100 burritos.
Step-by-step explanation:
Hope I helped ^u^
Colton can sell 20 tacos and 100 burritos.
What is inequality?An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.
Given that, Colton can make 120 tacos or burritos in total, the taco for $3.75 and each burrito for $6, He must sell at least $540 worth of tacos and burritos each day,
Establishing the inequality,
x + y ≤ 120............(i)
3.75x + 6y ≥ 540
0.625x + y ≥ 90...........(ii)
Plotting the graph, the solution will be the portion covered by both the inequality.
One of the possible solution is = (20,100)
Hence, Colton can sell 20 tacos and 100 burritos.
