how many pairs of whole numbers add up to 99

Simplify brackets

2/5(x - 4) = 2x

Simplify 2/5(x - 4) to 2(x - 4)/5

2(x - 4)/5 = 2x

Multiply both sides by 5

2(x - 4) = 10x

Divide both sides by 2

x - 4 = 5x

Subtract x from both sides

-4 = 5x - x

Simplify 5x - x to 4x

-4 = 4x

Divide both sides by 4

-1 = x

Switch sides

x = -1

Answer:

$613.35

Step-by-step explanation:

As 1.45% of employee's pay check goes to the Medicare, so

Total pay of Kasey in next year=$42300

Amount to be paid to medicare=1.45% of Kasey^' s pay

=42300*  1.45/100

=42300*  145/10000

=  6133500/10000

=613.35

Kasey will have to pay $613.35 to Medicare.

Final answer:

The quintic binomial among the options given is B: 3[tex]x^5[/tex] + 2, as it has two terms and its highest degree is five.

Explanation:

The question asks to identify which polynomial is a quintic binomial.

A quintic polynomial is one where the highest degree of any term is five, and a binomial is a polynomial with exactly two terms.

Looking at the options provided, Option B: 3[tex]x^5[/tex] + 2 fits this description, as it has two terms and the highest degree is five.

Answer:

m∠GQF=23°

Step-by-step explanation:

This is equal to 23 degrees because you know that mFG is 46°. Now, you use a theorem similar to Peripheral ∠ Th. to get 23°

Answer:

[tex]m\angle GQF=23^{\circ}[/tex]

[tex]m\angle GPF=52^{\circ}[/tex]

Step-by-step explanation:

We have been given an image of a circle and we are asked find the measure of angle GQF and measure of angle GPF.

We know that the measure of an inscribed angle is half the measure of its intercepted arc. To find the measure of angle GQF we will divide the measure of its intercepted arc (FG) by 2.

[tex]m\angle GQF=\frac{1}{2}\times 46^{\circ}[/tex]

[tex]m\angle GQF=23^{\circ}[/tex]

Therefore, the m∠GQF is 23 degrees.

We know that measure of angle formed by two intersecting secants inside a circle is half the sum of their intercepted arcs.

[tex]m\angle GPF=\frac{1}{2}\times(\text{Measure of arc FG+arc QE})[/tex]

[tex]m\angle GPF=\frac{1}{2}\times(46^{\circ}+58^{\circ})[/tex]

[tex]m\angle GPF=\frac{1}{2}\times(104^{\circ})[/tex]

[tex]m\angle GPF=52^{\circ}[/tex]

Therefore, the m∠GPF is 52 degrees.

Answer:

A=777.54

Step-by-step explanation:

What you do is use the formula which is

a=2pirh+2pir^2.

The radius is half the diameter and the diameter is 15 so you take 15 and divide it by 2 to get 7.5.

The height is 9 m.

A=2(3.14)(7.5)(9)+2(3.14)(7.5)^2=777.54 m.

Answer:

 777.15 m^2

Step-by-step explanation:

To find the surface area of a cylinder

SA = 2 pi r h + 2 pi r^2

The area of the sides Plus the area of the top and bottom

We know the diameter is 15 so the radius  is 1/2 (15) = 7.5

SA = 2 * pi * (7.5) * 9 + 2  * pi * (7.5)^2

     = 135pi + 112.5pi

        247.5 pi

Approximating pi with 3.14

      247.5 (3.14)

     777.15 m^2

Answer:

116cm^2

Step-by-step explanation:

This problem is just a matter of finding the area of the large and the small circle. To find the area of the large circle, you will use the equation: A = pi*r^2 in the following manner:

A = pi*r^2

A = pi*6.5^2

A = pi*42.3

A = 133

Next, you need to subtract the smaller circle from the area to only have the shaded area. Do this like the following:

A = pi*r^2

A = pi*2.3^2

A = pi*5.29

A = 16.6

Lastly, you just need to subtract! Do this like the following:

A = 133 - 16.6 = 116.4cm^2 = 116cm^2

The area of shaded area is 116.14 cm²

The area of circle is given by

Wee have 2 radii

Lets find for the radius 2.3

A = π * 2.3²

A = 16.61

Now lets find for the radius 6.5

A = π * 6.5²

A = 132.73

Now

The shaded area is 132.75 - 16.61

Shaded area = 116.14

Since she has the most heads come up, making her chances to be best of getting heads.

-----------------------------------------------------------------------------------------------

Divide each of the four values (102, 164, 75, 139) by 250 to get

102/250 = 0.408

164/250 = 0.656

75/250 = 0.300

139/250 = 0.556

We see that Jessica's empirical probability of 0.556 is closest to that of 1/2 = 0.500 which is the theoretical probability of getting heads.

La réponse au problème 7

est B) Kelly

La réponse au problème 8

est D) Jessica

102/250 = 0,408

164/250 = 0,656

75/250 = 0,300

139/250 = 0,556

Nous voyons que la probabilité empirique de Jessica de 0,556 est la plus proche de celle de 1/2 = 0,500 qui est la probabilité théorique d'obtenir des têtes.

Answer:

440,000

Step-by-step explanation:

435, the ten thousands place is the 2 place in the 435, so 5 rounds up, so 440 is what it round o, and everything else becomes 0.

435,098 rounded to the nearest ten thousand place is Option (E) 440,000.

Rounding off is the process used when a number is formed from the approximated value to tens, hundreds or thousands places. Rounding off is applied to a certain number to find the closest value after that number.

The number given is 435098.

Thus rounding off the number to nearest thousand will give us the closest value after that number in the thousand place of the digit of number.

Therefore from the Options given, the correct rounded off number is Option (E) 440,000.

Answer:

5.9

Step-by-step explanation:

2X - 8 is used to represent Eight less than the product of two and a number X. ​

To represent "Eight less than the product of two and a number X" as an expression, we can use the following equation:

2X - 8

In this expression, 2X represents the product of two and the number X, and subtracting 8 from it gives us "eight less than the product of two and a number X."

The product of two and the number X is obtained by multiplying 2 and X, which gives us 2X.

The expression "2X - 8" then subtracts 8 from the product 2X. This subtraction of 8 represents "eight less than" the product of two and a number X.

Answer:

Customer has bought too much sand

Step-by-step explanation:

Given that the dimensions (Length, Width and Height) of rectangular box are = 6,5, 1.2.

Volume of a rectangular box = Length * Width * Height

=> 6*5*1.2

=> 36 cubic feet

As mentioned, customer bought a sand box and 40 cubic feet of sand.

So,

Volume of rectangular box (R) = 36 cubic feet

Volume of Sand (S) = 40 cubic feet

From analysis

S > R

Which shows that the capacity of sandbox is 36 cubic feet and volume is 40 feet that is a little greater than desired capacity.

Therefore, customer has bought too much sand.

Answer:

x=3

Step-by-step explanation:

27/x +29=38

Multiply all terms by x and cancel:

27+29x=38x

29x+27=38x(Simplify both sides of the equation)

29x+27−38x=38x−38x(Subtract 38x from both sides)

−9x+27=0

−9x+27−27=0−27(Subtract 27 from both sides)

−9x=−27

−9x

−9

=

−27

−9

(Divide both sides by -9)

x=3

To solve for x, subtract 29 from both sides, multiply both sides by x, then divide both sides by 9 to get x = 3.

To solve for x in the equation 27/x + 29 = 38, you first want to isolate the term with x. We can do that by subtracting 29 from both sides to get: 27/x = 38 - 29, simplified to 27/x = 9.

Next you want to get rid of the x in the denominator, which implies multiplication. You can multiply both sides of the equation by x, which will give: 27 = 9x.

To finally solve for x, divide both sides by 9 to get x = 27/9, so, x = 3.

Answer:

x=1 2/5

Step-by-step explanation:

Replace y with 0 and solve for x.

Answer:  The required zero of the given function is x = -1.4.

Step-by-step explanation:  We are given to find all the real zeroes of the following function :

[tex]y=-5x-7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Since the given function is linear, so it will have only one real zero.

Also, the zeroes of a function y = f(x) is given by f(x) = 0.

So, the zero of the given function (i) is

[tex]y=0\\\\\Rightarrow -5x-7=0\\\\\Rightarrow 5x=-7\\\\\Rightarrow x=-\dfrac{7}{5}\\\\\Rightarrow x=-1.4.[/tex]

Thus, the required zero of the given function is x = -1.4.
