Answer:
.
Step-by-step explanation:
Answer:
-56
Step-by-step explanation:
Let the said number be x, so

In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°. Find the length of r, to the nearest inch.
the value of r will be 970 inches Approx.
What are the properties of Triangle?The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
Given, In ΔPQR, p = 220 inches, q = 890 inches and ∠R=121°.
From the general formula of side of triangle:
c² = a² +b² - 2ab * cos ∠C
In Our case,
a = p = 220
b = q = 890.
c = r
∠C = ∠R = 121 degrees
Thus,
r² = 220² + 890² - 2*220*890 * cos 121°
r² = 941344.455067
r = 970.229073501
r = 970 inches Approx.
Therefore, the value of r will be 970 inches Approx.

Find the sum of 3x + y , - 4x -2y
Answer:
(-x-y)
Step-by-step explanation:
Given data
First expression = ( 3x + y)
Second expression = (-4x -2y)
Add the two expresssion
= ( 3x + y)+ (-4x -2y)
Open bracket
=3x+y-4x-2y
collect like terms
=3x-4x+y-2y
=-x-y

The library is having a book sale. Hardcover books sell for $4 each, and paperback books are $2 each. If Ayanna spends $26 for 8 books, how many hardcover books did she buy?
Answer:
5 hardcover books
Step-by-step explanation:
x + y = 8 ↔ Assume x for hardcover books and y for paperback cover
4x + 2y = 26 ↔ Total cost of 8 books is $26
-2x - 2y = -16 ↔ Multiply Equation 1 by -2 so that the coefficients of y is opposite
2x = 10 ↔ Add the two equations to eliminate y
x = 5 ↔ Divide each side by 2

List the steps to solve the fol
lowing equation:
5x - 6 = 44. Then solve for x
Answer:
x = 10
Step-by-step explanation:
Simplifying
5x + -6 = 44
Reorder the terms:
-6 + 5x = 44
Solving
-6 + 5x = 44
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 5x = 44 + 6
Combine like terms: -6 + 6 = 0
0 + 5x = 44 + 6
5x = 44 + 6
Combine like terms: 44 + 6 = 50
5x = 50
Divide each side by '5'.
x = 10
Simplifying
x = 10

Margaret deposits $1,000 in a savings account that pays 1.4% interest compounded
semiannually. What is her balance after 1 year?
Answer:
The balance after 1 year is;
$1,014.05
Step-by-step explanation:
To do this, we use the compound interest formula
That will be ;
A =P (1 + r/n)^nt
A is the amount generated which we want to calculate
r is the rate = 1.4% = 0.014
P is the amount deposited = $1,000
n is the number of times it is compounded annually which is 2 (semi-annually means 2 times in a year)
this the number of years which is 1
we have this as:
A = 1,000( 1 + 0.014/2)^(2*1)
A = 1,000(1 + 0.007)^2
A = 1,000(1.007)^2
A = $1,014.05
