Answer:

the new monthly salary after both increase is 1,788.37

Step-by-step explanation:

The monthly salary is 1,622.31

There is an increase of 3.8%

So, the salary after first increase is

= 1,622.31 × (1 + 3.8%)

= 1,683.96

Now there is a second increase of 6.2%, so the salary after second increase is

= 1,683.96 × (1 + 6.2%)

= 1,788.37

Hence, the new monthly salary after both increase is 1,788.37

Answer:

The equation is ;

4x - y = 13

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from what we are given, let us write the second equation in the general form

x + 4y = 10

4y = -x + 20

y = -1/4x + 20/4

y = -1/4x + 5

mathematically, when two lines are perpendicular, the product of their slope is -1

So for the second line with slope m2

m2 * -1/4 = -1

m2 = 4

So, using the general form, we have the equation as;

y = 4x + b

To get the value of b, we substitute the coordinates of the given point (3,-1)

-1 = 4(3) + b

-1 = 12 + b

b = -1-12

b = -13

So the equation is;

y = 4x - 13 which can be rewritten as;

4x-y = 13

Answer:

  H  f(x) = -0.5(x -3)² +2

Step-by-step explanation:

The quadratic opens downward, so the leading coefficient is negative. All answer choices agree on this.

The vertex (maximum point) is (3, 2). Choices F and H are written in vertex form. Choice F has a vertex of (3, 8); choice H has a vertex of (3, 2), so is a likely candidate.

When we look at the graph 1 unit right or left of the vertex, we see that it is about 1.5, that is, 0.5 units below the vertex. This 0.5 is the magnitude of the leading coefficient, which we already know is negative. The leading coefficient of -0.5 eliminates choices F and G.

So, choice H has the correct leading coefficient and the correct vertex.

Choice J can be eliminated by looking at the value for x=0. For J, it is -6, but we see the y-intercept of the graph is -2.5. This eliminates choice J.

The only viable choice is H.

Answer:

Median without outlier should be 40

For the bottom questions, it should go:

Decreases the mean, does not change the median, does not change the mode

It's decreasing the mean because it goes from 44.7 to 39

Median w/ and without outlier is both 40

Mode also stays the same w/ or without the outlier, which is 96

Step-by-step explanation:

im doing this problem right now---

ok so a1=256 a2=64 a3=15 a4=4... find a9

the sequence divides by 1/4 every term

an=a1*r^n-1

an=(256)*(1/4)^n-1

replace n with 9

A9=(256)*(1/4)^9-1

A9=(256)*(1/4)^8

=(256)*(1/4)

A9=64^8

1/256 or a9= 0.00390625

Answer:

720 mL ; 1080 ml

Step-by-step explanation:

Givenn:

Apple syrup : water = 2 : 3

Fruit juice volume made using the ratio above = 1800 ml

Sum of ratio = 2 + 3 = 5

Litres of Apple syrup :

(Syrup ratio / total) * total volume of fruit

(2 / 5) * 1800

= 0.4 * 1800

= 720 ml

Litres of water :

(water ratio / total) * total volume of fruit

(3 / 5) * 1800

= 0.6 * 1800

= 1080 ml

Answer:

Its A

Step-by-step explanation:

The (8,-2) is the coordinates of V.

We have given that,

IT TUVW is reflected across the line y = .x,

We have to determine the coordinates of V

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y-axis. The coordinates of a given point represent how far along each axis the point is located.

Therefore the (8,-2) are the coordinates of V.

The given decimal 0.69789978997899789 is irrational since 7899 is repeating.

Any real number that cannot be written as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number.

In another word, irrational numbers are those numbers that can not terminate.

For example, √2, and √3 are irrational numbers because they cannot be written as p/q where p and q both should be integers.

Given the decimal

0.69789978997899789

Now if we see then 7899 is repeating it means it will going to repeat and it ends so it is not apple to write in form of p/q so it will be an irrational number.

Hence "The given decimal 0.69789978997899789 is irrational since 7899 is repeating".

Answer:

Exceeded by 145 dollars.

Step-by-step explanation:

First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.

Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.

Subtract 500 from 645 and you get the answer of 145.

So they exceeded 145 dollars.

Answer:

382 inches

Step-by-step explanation:

Given that :

The size of the soccer ball that Adrian and Violetta got is = 4

The diameter of the soccer ball is = 9 inches

Therefore, the radius of the soccer ball is, r = [tex]$\frac{9}{2}$[/tex]  inches

So the volume of the soccer ball is :

[tex]V = \frac{4}{3} \pi r^3[/tex]

[tex]V = \frac{4}{3} \times \frac{22}{7} \times \left(\frac{9}{2}\right)^3[/tex]

[tex]V = \frac{4}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times \frac{9}{2}[/tex]

Answer:

Option 2

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.

So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.

Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:

[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]

The end result matches with the equation determined before, so option A is the answer.
