m<2 is on the number line of the inequality 45>32m–19

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 45>32m–19

Forty five greater than thirty two times of m minus nineteen

m is the variable in the inequality

45>32m–19

Add 19 on both sides

64>32m

Divide both sides by 32

2>m

m<2

Hence, m<2 on the number line of the inequality 45>32m–19

Answer: P= 30° & R= 60°

Step-by-step explanation:

First, you should find angle "R" as it helps find angle "P"

therefore:

R= 180°- 120°(angles on a straight line add up to 180°)

 = 60°

P= 180°- ( 90°+ 60°) (Angles of a triangle add up to 180°)

 = 180°- 150°

Answer:

a) 40cm²

b) 150cm²

Step-by-step explanation:

a)

The area of the shaded region is equal to the area of the larger rectangle, minus the area of the smaller rectangle.

Knowing the formula for the area of a rectangle is bh (where b is base and h is height), we can find

Large rectangle area: bh = (20)(10) = 200cm²

Smaller rectangle area: bh = (12)(10) = 120cm²

The area of the shaded region is therefore 200-120cm²=80cm²

b)

The area of the shaded region is equal to the area of the larger triangle, minus the area of the smaller triangle.

Knowing the formula for the area of a triangle is 0.5bh (where b is base and h is perpendicular height), we can find

Large triangle area: 0.5bh = 0.5(20)(20) = 10(20) = 200cm²

Smaller triangle area: 0.5bh = 0.5(20)(5) = 10(5) = 50cm²

The area of the shaded region is therefore 200-50cm²=150cm²

Answer:a) 140 cm^

b)150m^2

Step-by-step explanation:

a)first find the area of big rectangle i.e rectangle

area of rectangle 1 = length ×breadth

area of rectangle = 10×20=200cm^2

now find area of small rectangle i e rectangle

area of rectangle 2 = 12×5=60cm^2

now subtract area of rectangle 2 from area of rectangle

area of shaded portion =200-60= 140cm^2

b)find area of big triangle i.e triangle 1....

area of triangle 1 = 1/2 × base × height...

area of triangle 1 =1/2×20×20 = 200m^2

area of triangle 2 =1/2×10×5 =25m^2

area of triangle 3=1/2×10×5= 25m^2

area of shaded portion = area of triangle 1 - area of triangle 2 - area of triangle

area of shaded portion =200-25-25 =150m^2

The original dimensions of the garden are width of 10 feet and a length of 12 feet.

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation.

Let's call the width of the garden w.

According to the problem, the length of the garden is 2 feet more than its width:

Length = w + 2

And the area of the garden is 120 square feet:

Area = Length * Width

Substituting the expression for Length from the first equation into the second equation:

Area = (w + 2) * w

Expanding the expression:

Area = w² + 2w

Setting the expression for the area equal to 120:

w² + 2w = 120

Expanding the expression to a quadratic equation:

w² + 2w - 120 = 0

Solving for w using the quadratic formula:

Factor the left side of the equation.

(w − 10)(w + 12) = 0

w − 10 = 0 or w + 12 = 0

w = 10 or w = − 12

Since width cannot be negative, the width is 10 feet.

Length = w + 2 = 10 + 2 = 12 feet.

The required measure of m ∠Q is 46 degrees for the given figure.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As per the corresponding angles property, we can write the equation would be as:

17x = 56 + (8x-2)

17x - 8x = 56 - 2

9x = 54

x = 6

Since m ∠Q = 8x-2

So substitute the value of x = 6 in the above equation,

Then, we get m ∠Q = 8(6) - 2 = 46 degree

The equation in simplified slope-intercept form is y = (2/3)x + 4/3.

What is the slope-intercept form of the line?

The slope-intercept form is a way of writing a linear equation in the form of y = mx + b, where m is the slope of the line and b is the y-intercept.

To rewrite the equation 2x-3y+4=0 in simplified slope-intercept form, we need to rearrange the equation to get y by itself on one side of the equation.

To do this, we can add 3y to both sides of the equation:

2x + 4 = 3y

Then we can divide both sides by 3:

(2/3)x + 4/3 = y

Now we have the equation in the form of y = mx + b, where m is the coefficient of x, which is (2/3) and b is the constant term on the right side, which is 4/3.

Hence, the equation in simplified slope-intercept form is y = (2/3)x + 4/3

The yield to maturity of this STRIP is 1.36%

percentage, a relative value indicating hundredth parts of any quantity.

Current price = $96

Par Value = $100

Time to Maturity = 3 years

Semiannual Period = 3 × 2 = 6

The yield to maturity of this STRIP will be calculated as:

Let the semiannually yield to maturity be represented by y.

96 = 100/(1 + y)⁶

Cross multiply

96(1+y)⁶= 100

Divide both side by 96

(1+y)⁶= 100/96

(1+y)⁶= 1.0417

1 + y⁶ = 1.0417

y⁶ = 1.0417 - 1

y⁶ = 0.0417

y = 0.0068

Therefore, the semiannual YTM = 0.0068

Annual YTM will now be:
