Answer:

A: 8.4

Step-by-step explanation:

Order of operations: BEDMAS. Brackets, exponents, division, multiplication, addition, and substraction.

Using this you need to do 2(1.2) first.

2(1.2)=2.4

Then 4.5-2.4=2.1

Then finally 4(2.1)=8.4

Hope that helps

Answer:

Step-by-step explanation:

Mean = (98+92+90+78+83+88+95)/7

= 89.1   to nearest tenth.

Deviations:

98 - 89.1 = 8.9

92 - 89.1 = 2.9

90 - 89.1 = 0.9

78 - 89.1 = -11.1 = 11.1  (absolute value)

83 - 89.1 =  6.1

88-89.1 = 1.1

95 - 89.1 = 5.9

So the MAD

= (8.9+2.9+0.9+11.1+6.1+1.1+5.9)/7

= 36.9/7

= 5.27

= 5.3 to nearest tenth.

Answer:

A. 9y + 3 = 0

Step-by-step explanation:

To know if a function is linear without graphing it, check if the function is a polynomial of the first degree, because linear functions are polynomials of the first degree. This means that the power of the x-value should be equal to 1.

The only function without this trait is 9y + 3 = 0, so that is our nonlinear function.

she would earn $73,850 annualy(sry for my mistakes im in 6th Grade) and the question says how much more will she arn each year as a CPA than as an accountant each year and she would make 68,150 as an accountant so you would subtract 73,850 by 68,150 and you would get $5,700.

The vertex form of the given equation, y = -6x² + 3x + 2, is expressed as: y = -6(x - 0.25)² + 2.375.

The vertex form of an equation is expressed as, y = a(x - h)² + k, where:

(h, k) = vertex of the parabola.

Given the equation, y = -6x² + 3x + 2, factor the equation:

y = -6(x² - 0.5x) + 2

y = -6(x² - 0.5 + 0.0625) + 2.375

Rewriting the equation as perfect squares, we would have:

y = -6(x - 0.25)² + 2.375

The vertex form of y = -6x² + 3x + 2 is, y = -6(x - 0.25)² + 2.375.

Answer: 230.4 feet

Step-by-step explanation:

arc length = circumfrance x fraction of a circle

                 = [tex]2\pi r[/tex] x [tex]\frac{165}{360}[/tex]

                 = [tex]\frac{2*\pi *80*165 }{360}[/tex]

                 = 230.4 feet to nearest tenth

The length of the intercepted arc between those two cars on the Ferris wheel is 230.4 feet. This is obtained by using the arc length formula in degrees.

The distance across the curved length is said to be arc length.

The arc length is calculated by using the formula:

arc length = circumference × fraction of circle

⇒ arc length = 2πr × θ/360° when θ is given in degrees

where r is the radius.

Given that,

A Ferris wheel has a radius of r=80 feet

Two particular cars are located such that the central angle between them is 165° i.e., θ = 165°

arc length = 2πr × θ/360°

⇒ 2π×80×[tex]\frac{165}{360}[/tex]

⇒ 230.38 feet

Rounding off to the nearest tenth, we get arc length = 230.4 feet.

The amount spent is an illustration of subtraction and proportions

The amount left in his earnings is $414.25

The given parameters are:

Rate = $22 per hour

Time = 40 hours

So, the total earnings is:

Total = $22 * 40

Evaluate

Total = $880

He spent half on bills.

So, we have:

Bills = 0.5 * $880

Bills = $440

He buys a video game for $25.75

Answer:

Step-by-step explanation:

2(x+7)^2 =98  

(x+7)^2 = 49  (divide both sides by 2)

(x +7) = [tex]\sqrt{49}[/tex]  (square root both sides)

x + 7 = 7  ( we are not sure if this is  -7 or  +7, because either would work )

so we have two solutions now

x +7 = -7     or      x +7 = 7

x = -7 -7      or      x =7 -7    (subtract 7 from both sides)

x = - 14        or      x = 0

x = 66

Step-by-step explanation:

the triangle has 2 congruent sides and is therefore isosceles with the 2 base angles being congruent, then

x = 66

The measure of the indicated angle is 66 degree.

An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:

We have a Triangle.

Then, using Isosceles Triangle Theorem

Angles opposite an isosceles triangle's equal sides are also equal.

According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.

So, x= 66 degree.

In which:

Hence, for Lincoln, we have that the parameters are as follows:

P = 49000, r = 0.06125, n = 365, t = 20.

Hence the amount will be of:

[tex]A_L(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]A_L(20) = 49000\left(1 + \frac{0.06125}{365}\right)^{365 \times 20}[/tex]

[tex]A_L(20) = 166787[/tex]

The amount is given by:
