65% of what is
42.9 ?

Answer:

67/25's

Step-by-step explanation:

2 and 68/100's

Reduce 68/100 to 17/25

50/25=2

So, add (50/25)+(17/25) to make (67/25)

Answer:

(p - 5)(p + 1)

Step-by-step explanation:

Given

p² - 4p - 5

Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

The factors are - 5 and + 1 , since

- 5 × + 1 = - 5 and - 5 + 1 = - 4, then

p² - 4p - 5 = (p - 5)(p + 1) ← in factored form

The standard form of a trinomial is

ax² + bx + c ( a ≠ 0 )

p² - 4p - 5 ← is in standard form

with a = 1, b = - 4 and c = - 5

Answer:

a = 2 √13 cm

Step-by-step explanation:

Here, we want to find the length of BC

To do this, we can use the cosine rule

Thus;

a^2 = b^2 + c^2 - 2BC cos A

= 8^2 + 6^2 - 2(8)(6) cos 60

Mathematically cos 60 = 1/2

= 64 + 36 - 48 = 52

a^2 = √52

a = 2 √13 cm

Answer:

b = -(4a + c)/4

Step-by-step explanation:

sum of a, b, and c is five times the sum of a and b,

a + b + c = 5(a + b)

which of the following expresses the value of b in terms of a and c?

a + b + c = 5(a + b)

a + b + c = 5a + 5b

a + c - 5a = 5b - b

-4a + c = 4b

b = -(4a + c)/4

Answer:

19) 0.8000

20) 0.8824

21) 0.2800

22) 1.8750

23) 0.8000

24) 0.8000

Step-by-step explanation:

sin = opp/hyp

cos = adj/hyp

tan = opp/adj

19) sin Z = 40/50 = 0.8

20) sin C = 30/34 = 0.882352941

21) sin A = 7/25 = 0.28

22) tan X = 30/16 = 1.875

23) cos X = 28/35 = 0.8

24) cos C = 36/45 = 0.8

Answer:

a. 8,250

b. 0

Step-by-step explanation:

a) -2,750 (5) = -13, 750 + 22,000 = 8,250

b) -2,750 (8) = -22,000 + 22,000 = 0

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The worth of the car after 5 years is $8350

The worth of the car after 8 years is $0.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 5 = 8 is an equation.

We have,

The straight-line depreciation equation for a car is

y = -2,750x + 22,000.

The worth of the car after 5 years.

= -2750 x 5 + 22000

= -13750 + 22000

= 8350

The worth of the car after 8 years.

= -2750 x 8 + 22000

= -22000 + 22000

= 0

Thus,

The worth of the car after 5 years is $8350

The worth of the car after 8 years is $0.

Answer:

hypotenuse =13cm

base=10cm

perpendicular =?

Step-by-step explanation:

by using Pythagoras law

hypotenuse=perpendicular²+base²

13²=perpendicular²+10²

perpendicular =√(13²-10²)=√69=8.3cm

the measure of the other leg is 8.3cm

The measure of the other leg is 8.3 cm .

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Formula of Pythagoras theorem :

(Hypotenuse)² = (Base)² + (Perpendicular)²

According to the question

Hypotenuse of a right triangle = 13 cm

Perpendicular of a right triangle = 10 cm

Now,

Base of a right triangle  

By using formula of Pythagoras theorem :

(Hypotenuse)² = (Base)² + (Perpendicular)²  

Substituting the values

(13)² = (Base)² + (10)²  

169 = (Base)² + 100

69 = (Base)²

Base = [tex]\sqrt{69}[/tex]

Base = 8.3 cm

Hence,  the measure of the other leg is 8.3 cm .

Answer:

function is [tex]y = 3 (6^{x})[/tex]

Step-by-step explanation:

The general form for an exponential function is [tex]y = kb^{x}[/tex].   We need to find both k and b

(0, 3) is a point on the graph.  So, let's substitute 0 in for x and 3 in for y

[tex]3 = k b^{0} = k(1) = k[/tex]

Now we know that k = 3

(1, 18) is a point on the graph.  So, let's substitute 1 in for x, 18 in for y and 3 in for k

[tex]18 = 3 b^{1} = 3b\\6 = b[/tex]

Now we know that b = 6

Therefore, the function is [tex]y = 3 (6^{x})[/tex]

x in (-oo:+oo)

y = (5/4)*x-(7/4) // - (5/4)*x-(7/4)

y-((5/4)*x)+7/4 = 0

(-5/4)*x+y+7/4 = 0

y-5/4*x+7/4 = 0 // - y+7/4

-5/4*x = -(y+7/4) // : -5/4

x = (-(y+7/4))/(-5/4)

x = 4/5*(y+7/4)

x = 4/5*(y+7/4)

Answer:

Area of rectangle = 54

Area of triangle= 18

Total area = 72

Step-by-step explanation:

Area of rectangle = length × width

= 9 × 6

= 54

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

[ Height of the triangle = 10 - 6 = 4 ]

Area of a triangle = [tex]\frac{1}{2}[/tex] × 9 × 4

= 18

Total area = Area of rectangle + Area of triangle

= 54 + 18

= 72

[ The unit should be: [tex]cm^{2}[/tex] or [tex]m^{2}[/tex] etc.; it should have the 'square'. ]
