Answer:

5b - 5a

Step-by-step explanation:

b(5 - a) = 5b - ab

- a(b - 5) = - ab + 5a

Subtracting gives

5b - ab - (- ab + 5a) ← distribute parenthesis by - 1

= 5b - ab + ab - 5a ← collect like terms

= 5b - 5a

Answer: 720 I think

Step-by-step explanation: Because if there are 720 cubic units, you can only fit 720.

There will be 720 cubes of side 1 unit that fill the prism if they were packed without any gaps or overlaps.

Volume is defined as the space occupied within the boundaries of any three-dimensional solid.

Given that, a rectangular prism has a volume of 720 cubic units, we need to find that, how many unit cubes would fill the volume with the solid if they were packed without any gaps or overlaps,

So, to find the same, we will divide the volume of the prism by the cube.

Volume of the cube = side³ = 1³ = 1

Therefore, number of cubes to be fitted = 720 / 1 = 720

Hence, there will be 720 cubes of side 1 unit that fill the prism if they were packed without any gaps or overlaps.

The required functions are obtained as f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.

The inverse of a function y = f(x) is defined as a function having range as the domain of the function f(x) and domain as the range. Mathematically it can be written as f⁻¹(y) = x which implies that f⁻¹(f(x)) = x.

The given problem can be solved as follows,

(a) f⁻¹(x) = 5x

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = 5f(x)

=> x = 5f(x)

=> f(x) = x/5

(b) f⁻¹(x) = x³/2

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = f(x)³/2

=> x = f(x)³/2

=> f(x) = ∛(2x)

(c) f⁻¹(x) = x + 10

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = f(x) + 10

=> x = f(x) + 10

=> f(x) = x - 10

(d)  f⁻¹(x) = 3( x + 17)/2

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = 3( f(x) + 17)/2

=> 2x = 3( f(x) + 17)

=> 2x/3 = f(x) + 17

=> f(x) = 2x/3 - 17

Hence, the functions for the given inverse functions are  f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.

First divide $20.42 by 10 to find the cost of 1 pound/16 ounce turkey.

Dividing, this gives us 2.042.

Now, to find the cost of a 21-pound turkey, we multiply

the cost of 1 turkey by 21 to get 42.882.

So a 21-pound turkey is $42.882.

Answer:

Step-by-step explanation:

Let x be the random variable. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 474

σ = 32

x = 514

The probability of being below 514 is expressed as P(x < 514)

For x = 514,

z = (514 - 474)/32 = 1.25

Looking at the normal distribution table, the probability value corresponding to area below the z score is 0.89

Therefore,

P(x < 514) = 0.89

Answer:

31

Step-by-step explanation:

Let the numbers be x and y.

"The sum of two numbers is 43." gives us the first equation.

x + y = 43

"One number is five less than three times the other number." gives us the second equation.

y = 3x - 5

Now we solve the system of two equations below.

x + y = 43

y = 3x - 5

Since the second equation is already solved for y, we will use the substitution method. We substitute 3x - 5 for y in the first equation.

x + y = 43

x + 3x - 5 = 43

4x - 5 = 43

4x = 48

x = 12

The first number is 12. Now we find the second number.

x + y = 43

12 + y = 43

y = 31

The larger number is 31.

Answer:

31 is greater

Step-by-step explanation:

I will solve your system by substitution.

x=3y−5;43=x+y

Step: Solve x=3y−5 for x:

Step: Substitute 3y−5for x in 43=x+y:

43=x+y

43=3y−5+y

43=4y−5 (Simplify both sides of the equation)

43+−4y=4y−5+−4y (Add -4y to both sides)

−4y+43=−5

−4y+43+−43=−5+−43 (Add -43 to both sides)

−4y=−48

(Divide both sides by -4)

y=12

Step: Substitute12foryinx=3y−5:

x=3y−5

x=(3)(12)−5

x=31(Simplify both sides of the equation)

Answer:

x=31 and y=12

Answer:

x = 24°

Step-by-step explanation:

Lines JH and EG are the parallel lines and HF is a transverse.

∠JHF ≅ ∠HFE [Interior alternate angles]

m∠JHF = 2x

Since, m∠JHF = m∠JHG + m∠FHG

2x = m∠JHG + x

m∠JHG = 2x - x = x

Since m∠JHI + m∠JHG = 180° [Supplementary angles]

156° + m∠JHG = 180°

m∠JHG = 180 - 156

m∠JHG = 24°

x = 24°

Therefore, x = 24° will be the answer.

Answer:

one halfk + 5

Step-by-step explanation:

The expression (1/2)k + 5 represents Jonah's earnings option (B) one-half k + 5 is correct.

It is defined as the combination of constants and variables with mathematical operators.

A linear equation can be defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Jonah earned $5 more than half of Karen's salary, k

Let Jonah's salary is J

J = 5 + (1/2)k

Or

= (1/2)k + 5

The above expression represents Jonah's earnings and the expression is a linear expression.

Thus, the expression (1/2)k + 5 represents Jonah's earnings option (B) one-half k + 5 is correct.

The solution is Option D.

The triangle is a right scalene triangle

A scalene triangle is a type of triangle with three different length sides and three interior angles that add up to 180 degrees. Scalene triangles have no equal of parallel sides , hence there is no line of symmetry. The interior angles of a scalene triangle can be acute , right or obtuse angles.

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

The measures of the sides of the triangles are 3.4 cm , 4 cm and 5.2 cm

The measures of angles of triangle are 40°, 50°, and 90°

Since the triangle is having all its length and sides different , it is a scalene triangle

Now , For a right angle triangle

hypotenuse² = base² + height²

( 5.2 )² = ( 3.4 )² + ( 4 )²

( 5.2 )² = 11.56 + 16

( 5.2 )² = 27.56

Hence , the triangle is a right scalene triangle

Hello I think the answer would be 7

An angle bisector, bisects an angle into two equal small angles

14 divided by 2 is 7

Hope this helps :)

The measure of each new angle will be 7°.

Since we are given the information that the original angle had a measure of 14 degrees, then when the angle is bisected, forming two new angles, we have to divide the original angle by 2. This will be:

= 14°/2

= 7°

Therefore, the measure of each new angle will be 7°.

Area of the frame not covered with photo is equal to 129 square inches

Step-by-step explanation:

Given: Image of a frame

To find: Area of the frame not covered by the picture

Solution:

Area of rectangle = length of the rectangle × breadth of rectangle

Area of the frame = length of frame × breadth of frame = 23 × 15 = 345 square inches

Area of the frame covered with photo = 18 × 12 = 216 square inches

Area of the frame not covered with photo = Area of the frame - Area of the frame covered with photo = 345 - 216 = 129 square inches
