Answers

The measure of the angle m∠J is  35°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.

Consider the triangle KJL,

The line KM is perpendicular to the line JL and M is the midpoint of the line JL.

Therefore, the angle KMJ will be equal to 90°.

Now, we have the angle KJM is equal to 55°.

We know the sum of all interior angles of a triangle is 180°.

So,

In triangle JKM,

∠JKM + ∠KJM + ∠KMJ = 180°

∠JKM + 55° + 90° = 180°

Subtracting 90° from each side of the equation.

∠JKM + 55° + 90° - 90° = 180° - 90°

∠JKM + 55° = 90°

Subtracting 55° from each side of the equation.

∠JKM + 55° - 55° = 90° - 55°

∠JKM = 35°

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound and 9 pounds of pears at $2.35 per pound. If she paid with a $50 bill, how much change did she receive? Hint* USE THE $ SIGN IN YOUR ANSWER. YOUR ANSWER SHOULD HAVE 2 DECIMAL PLACES.

Answers

Answer:

$17.60

Step-by-step explanation:

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound

1 pounds = $5

2 1/4 pounds = x

x = 2 1/4 × $5

x = 9/4 × $5

x = $45/4

x = $11.25

9 pounds of pears at $2.35 per pound.

1 pound = $2.35

9 pounds = x

x = 9 × $2.35

x = $21.15

Total amount that she spent =

$11.25 + $21.15

= $32.40

If she paid with a $50 bill, how much change did she receive?

The change she received =

$50 - $32.40

= $17.60

What is the solution to the equation –3.5(x + 12) = –2x + 18?

Answer:

x = -4.36364

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3.5(x + 12) = -2x + 18

Step 2: Solve for x

Distribute 3.5:                    3.5x + 42 = -2x + 18Add 2x on both sides:       5.5x + 42 = 18Isolate x term:                    5.5x = -24Isolate x:                             x = -4.36364

Answer:

The answer I arrived at was x = -4.364

Step-by-step explanation:

3.5(x + 12) = -2x + 18

=> multiply 3.5 by everything in parenthesis

3.5x + 42 = -2x + 18

=> subtract 18 from both sides

3.5x + 24 = -2x

=> subtract 3.5x from both sides

24 = -5.5x

=> divide both sides by -5.5

-4.364 = x

What is the sum of 3x² - x -2 and x² + 2x - 1?

Answers

Line the equations up based on their common factor. Keep in mind the X has an understood 1 in front of it if there is no coefficient. So, X = (1)X. Add them up as shown in the picture.

3x^2 + (1)x^2 = 4x^2

-(1)x + 2x = (1)x

-2 + -1 = -3

Then put these in order based on their variable (same order as in the original equations) don’t include the understood one when writing your final equation as some teachers may take off points for it.

Final answer= 4x^2 + x - 3

Answer:

Step-by-step explanation:

We can combine like terms in order to find this sum: 3x^2 + x^2 +2x -x -2-1= 2x^2 +x -3.

Answers

Answer:  second and fourth choices have infinitely many solutions

Step-by-step explanation:

When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.

x - 1/3(3x) = 0 . 1/3 of 3x is 1x

x - x = 0  any number minus itself is 0

or add x to both sides  x-x+x = 0 + x  

x = x is an identity. An identity has infinite solutions.

3x + 2 - 1/3(3x) = 2 + 2x

3x + 2 -x = 2 + 2x

2x +2 = 2 + 2x . same thing! Infinite solutions.

The circumference of a circle is 17π ft. What is the area, in square feet? Express your answer in terms of \piπ.

Answers

The answer for this question is 72.25pi

The area of the circle is 72.25π ft².

What is Surface Area?

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.

As per the given data:

circumference of a circle = 17π ft

To find the area of the square:

Area = πR²

For radius (R):

2πR = 17π

R = (17/2) ft

Area = π(17/2)²

= 72.25π ft²

Hence, the area of the circle is 72.25π ft².

1.6 x 10^4

Step-by-step explanation:

First, 8*2 = 16

Since we are using scientific notation, this is expressed as 1.6 * 10^1

When we multiply using scientific notation, we add the exponents, therefore, 10^-2 x 10^5 = 10^3

1.6 x 10^1  x 10^3
