Step-by-step explanation:
Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:
21
1
So now that we've converted 21 into a fraction, to work out the answer, we put the fraction 2/7 side by side with our new fraction, 21/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:
2 x 21
7 x 1
=
42
7
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 42 and 7 is 7.
We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.
42/7 = 6
7/7 = 1
When we put that together, we can see that our complete answer is:
6
1
The complete and simplified answer to the question what is 2/7 of 21 is:
6

find the value of X and Y
Answer:
x=10
y=9
Step-by-step explanation:
The value of x and y is 5√2.
what is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
Hypotenuse= 10
angle= 45
Using Trigonometry
sin 45= P/H
1/ √2= P/ 10
P= 10/√2
P= 5√2
and, tan 45 = P/B
1 = 5√2/ B
B= 5√2
Hence, the value of x and y is 5√2.

Use the multiplier method to increase £258 by 43%
You must show your working out.
Answer:
£368.94
Step-by-step explanation:
The multiplier for 43% is 0.43
0.43 x 258 = 110.94 which is 43%
But if you are increasing 258 by 43% you must add on 258 as well
Or instead you can just do 258 x 1.43= 368.94

Find the midpoint of the line segment with end coordinates of:(−1,−6) and (4,5)
Give coordinates as decimals where appropriate.
The midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).
Finding the midpoint of the line segmentThe midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates:
((x1 + x2)/2, (y1 + y2)/2)
In this case, the endpoints are (-1, -6) and (4, 5), so we can plug in the values:
((x1 + x2)/2, (y1 + y2)/2) = ((-1 + 4)/2, (-6 + 5)/2)
Simplifying this expression, we get:
((x1 + x2)/2, (y1 + y2)/2) = (3/2, -1/2)
Therefore, the midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

Joe buys candy that costs $7 per pound. He will spend at least $56 on candy. What are the possible numbers of pounds he will buy?
Answer:
8 pounds(lbs)
Step-by-step explanation:
If a candy costs $7 per pound, $56 divided by $7 will equal 8 pounds.
Answer:
8 ≤ x pounds
Step-by-step explanation:
I will be using * as a symbol for multiplication.
We can create an inequality for this question.
x will represent the amount of pounds that he may buy.
56 ≤ 7 * x
(This means that 56 is less than or equal to 7 times x.)
We create this inequality because of how Joe will spend AT LEAST $56 dollars on candy. The amount of candy is not defined in the question.
Let's solve.
56 ≤ 7 * x
Divide by 7.
8 ≤ x
Joe will buy at least 8 pounds of candy,
Note the word at least. This states that he may buy more, however 8 is the minimal amount he will obtain.

Write an equation in point-slope form of the line that passes through the given point and with the given slope m
(-5,2), m=4
Answer:
[tex]y-2=4(x+5)[/tex]
Step-by-step explanation:
The given point is (-5, 2) and the slope is 4.
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
We will let (-5, 2) be (x₁, y₁) and will substitute 4 for m. Therefore:
[tex]y-(2)=4(x-(-5))[/tex]
Simplify:
[tex]y-2=4(x+5)[/tex]
