Answer:
R = 1.2%
Step-by-step explanation:
Given the following data;
Principal = 425
Time = 2
Simple interest = 10.20
To find the annual interest rate;
Mathematically, simple interest is calculated using this formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is simple interest. P is the principal. R is the interest rate. T is the time.Substituting into the equation, we have;
[tex] 10.20 = \frac {425*R*2}{100} [/tex]
[tex] 10.20 = \frac {850R}{100} [/tex]
Cross-multiplying, we have;
[tex] 1020 = 850R [/tex]
[tex] R = \frac {1020}{850} [/tex]
R = 1.2%
Therefore, the annual interest rate is 1.2 percent.
у= 4х + 3
у = -X - 2
Answer:
x = - 1
Step-by-step explanation:
y = 4x + 3
y = -x - 2
Find x:
4x + 3 = -x - 2
5x + 3 = - 2 (Adding x to both sides)
5x = - 5 (Subtracting 3 from both sides)
x = -1 (Dividing 5 from both sides)
Answer: x = - 1
In the summer reading program, a participant earns 50 stars for reading 10 books. The library tracks the number of stars (y, vertical
axis) and books (x, horizontal axis) on a graph. Which statements are correct?
A)
Point (5, 1) represents the unit rate.
B)
Point (1,5) represents the unit rate.
9
Point (0, 50) represents the unit rate.
D)
Point (100, 20) represents reading 20 books.
E)
Point (20, 100) represents reading 20 books
Answer:b and e
Step-by-step explanation:
Answer:
B and E
Step-by-step explanation:
This is because (1,5) represents the unit rate whilst, (20,100) represents reading 20 books.

what is the surface area of this shape?
Answer:
361.88 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(B.A) + PH
Where,
B.A = base area of triangular base = ½*bh = ½*8*6 = 24 in.²
P = perimeter of triangular base = 7.21 + 7.21 + 8 = 22.42 in.
H = height of the prism = 14 in.
Surface area of the prism = 2(24) + 22.42×14
= 48 + 313.88
= 361.88 in.²
The length of a rectangle is three times the width. The perimeter of the rectangle is 32 inches. What is the area of the rectangle (in square inches)?
Answer:
48 square inches
plz mark brainliest
Step-by-step explanation:
l= 3w
perimeter = 2(l+w) =2(3w+w) = 2(4w)= 8w
32=8w
w=32/8 =4 inches
l= 3(4) =12 inches
area = l×w = 12×4 = 48 square inches

Answer:
77.5 degrees and 102.5 degrees
Step-by-step explanation:
Given that : one angle is25 degrees greater than another. Let the two angles be represented by a and b. Since one angle is 25 degreess greater than another, then:
b = a + 25 degrees
But;
a + b = 180 degrees (sum of angles on a straight line)
a + a + 25 degrees = 180 degrees
2a = 180 degrees - 25 degrees
a = 77.5 degrees
b = 77.5 degrees + 25 degrees = 102.5 degrees
Therefore the measures of all angles formed by the lines is either 77.5 degrees or 102.5 degrees.

14 masons can build 2 houses in 6 months. Find how many houses 21 masons can build in the same duration.
Answer:
3 houses
Step-by-step explanation:
2 houses = 14 masons
1 house = 14 ÷ 2 = 7
Find out what 21 ÷ 7 is, which is 3.
So 21 masons can build 3 houses in 6 months.
b. , using the

HELP AGAIN PLEASE 20 POINTS What methods can be used to solve a system of equations and when would you use each? Be sure to include systems with nonlinear equations.
Answer:
The three ways to solve a system of equations are substitution, elimination, and graphing. You can use these methods to solve any system of equations, it just depends on which method you use.
Step-by-step explanation:
In the substitution method, you get one variable isolated on one side of an equation, then use that equation to substitute the variable with what it's equal to into the second equation to solve the equation.
In the elimination method, you get all the variables in your equations together one side, and the constant on the other. Then, multiply or divide one or two equations to get one variable with the same coefficient for both equations (be sure to multiply or divide both sides to each equation), and add or subtract the equations together to get rid of that variable (make sure to add the left sides of the equations together and the right sides of the equations together, no the opposite!) and solve the equation.
In the graphing method, you solve for y in each equation, graph both equations on a coordinate plane, and find the point of intersection for both lines to solve the equation (For example, if the point of intersection is (2, 7), the answer to your equation would be X = 2 and Y = 7).
Solve the system using the substitution method
x = -6y - 4
6x - 12y = 24
Answer:
x = 2, y = -1
Step-by-step explanation:
We have a solution system, x = -6y - 4 and 6x - 12y = 24.
Now, since are not only asked to use the substitution method, but at the same time know the value of x, let's plug the first system into the second.
x = -6y - 4
6(-6y - 4) - 12y = 24
-36y - 24 - 12y = 24
-48y - 24 = 24
Add 24 to both sides :
-48y = 48
Divide -48 by both sides :
y = -1
Now that we have y, we can replace it into the second system again to get x.
6x - 12(-1) = 24
6x + 12 = 24
Solve for x by first getting rid of 12 from both sides :
6x = 12
Divide 6 by both sides :
x = 2
Therefore, x = 2 and y = -1

Write the following ratio as a reduced fraction. Simplify your answer when possible: 22 to 42
Answer:
11 / 21
Step-by-step explanation:
The ratio 22 to 42 can be written as: 22 : 42, and in fraction form as:
22 / 42 in this fraction we can cancel a common factor of 2 from numerator and denominator, leaving us with the reduced fraction:
2 * 11 / (2 *21) = 11 / 21

The width of a rectangle, in centimeters, is 17 less than 4 times its length, in centimeters. The area
of the rectangle is 15 square centimeters. What is the width, in centimeters, of the rectangle?
Answer:
Step-by-step explanation:
W = 4L-17
LW = 15
L(4L-17) = 15
4L^2-17L-15= 0
L = [17 ±√(17^2-4(4)(-15))]/[2(4)] = 5,-3/4
-3/4 is an extraneous solution
L = 5 cm
W = 4L-17 = 3 cm
