Answer:

The intercepts are: (0, 3/7) and (-3/4, 0)

Step-by-step explanation:

If X=0

-4(0) + 7y = 3

7y = 3

Y = 3/7

If Y=0

-4x + 7(0) = 3

-4x = 3

X = -3/4

The total flowers in the garden white or pink is 8/15.

The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line.

In our garden, there are 2/3 total roses, making the total number of blooms that aren't roses 1/3

4/5 = 2/3 +1/3.

Since 3 is a division of 6, we must multiply by 6 to arrive at the solution.

4 x 6 =24

5 x 6 =30

24/30

Next, we calculate half of 30 and add it to get 3/3.

Then we find 1/2 of 30 and add this to make 3/3

Just like 1/2 of 2 = 1 and 2+1 = 3

30 / 2  = 15

15 + 30 =45

The answer is 24/45

We then reduce this fraction by 3 as 6 + 8 do not divide into 45

24/45 = 8/15

The total flower in the garden is 8/15

The proportion of white or pink flowers in the entire garden is 8/15.

Answer:

Step-by-step explanation:

You want the discriminant, roots, and graph of the quadratic function ...

 f(x) = 1/2x² -2x +10

The discriminant of the quadratic function

  y = ax² +bx +c

is ...

  d = b² -4ac

The given function has a=1/2, b=-2, c=10, so the discriminant is ...

  d = (-2)² -4(1/2)(10) = 4 -20 = -16

The discriminant of -16 means there will be two distinct complex conjugate roots.

The roots are ...

  x = (-b ±√d)/(2a)

  x = (-(-2) ±√(-16))/(2(1/2)) = 2 ±4i

A graph of the function is attached.

The account’s mean daily balance for April will be $105.7.

Mean is the total added values of all the data in a set divided by the number of data in the set.

The account had the following balances;

$501 for 23 days

$2428 for 3 days

$241 for 4 days.

To find the mean; add the total amount and divide by the total number of days

[tex]mean = \frac{501 + 2428 + 241}{23 + 3 + 4}[/tex]

Given that WXZ and YXZ are congruent based on side-angle-side congruency, we can prove the theorem that states "A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints." This theorem is often referred to as the "Perpendicular Bisector Theorem."

The required details for "Perpendicular Bisector Theorem" in given paragraph

The Perpendicular Bisector Theorem states that if a point is on the perpendicular bisector of a line segment, then it is equidistant from the segment's endpoints. This means that if we draw a line through a point that is perpendicular to a line segment, and that line passes through the midpoint of the segment, then the point is equidistant from the endpoints of the segment. In this case, we are given that line L is the perpendicular bisector of segment WY, and that Z is a point on L. We are also told that WXZ and YXZ are congruent based on side-angle-side congruency. Since WXZ and YXZ are congruent, it follows that WX and YX are congruent and that WZ and YZ are congruent. This means that the distances from Z to W and Y are equal, so Z is equidistant from W and Y.

Therefore, we can conclude that Z is a point on the perpendicular bisector of segment WY, and the Perpendicular Bisector Theorem is proved. The answer is C. "A point on the perpendicular bisector of a line segment is equidistant from the segment’s endpoints."

On solving the provided question, we got to know that side length of the square is 8 units.

Four sides that are equally spaced apart make up a square. Around us, a lot of things are rectangular. Equal sides and a 90° interior angle serve as a visual cue to identify a square. A closed square has four sides and exists in two dimensions (2D). A square has an equal number and parallel alignment of its four sides.

A four-sided shape known as a square has sides that are all the same length and angles that are all right angles with a 90 degree angle.

The Pythagoras theorem is a mathematical law that states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.

According to the given question:

∠S and ∠Q are right angles in RSTQ quadrilateral.

RTS and RTQ are right angled triangles.

Applying Pythagorean theorem on both the triangles

sin 35° = b + 60 / RT ⇒ RT = b + 60 / sin 35°

sin 35° = 4b / RT ⇒ RT = 4b / sin 35°

Since RT is common in both equations

b + 60 / sin 35° = 4b / sin 35°

b + 60 = 4b

3b = 60

b = 20

The y-intercept of the given line is 7/9.

Step-by-step explanation:

The y-intercept of a line is the point where the line crosses the y-axis.

So, to find the point where the line crosses the y-axis we must do x=0.

By substituting x=0 in the following equation, we get

=> 9y + 4(0) = 7

=> 9y = 7

=> y = 7/9

Hence, y = 7/9 is the y-intercept of the given line.

What is an isosceles triangle ?

A triangle with two equal-length sides is known as an isosceles triangle (/assliz/). The term "equilateral triangle" can refer to a shape with either exactly two sides that are the same length or at least two sides that are the same length, with the latter definition containing the equilateral triangle as an exception.

Let the vertex angle to be 'x'

So, according to the question, the measure of the base angels in an isosceles triangle is 8 less than 3 times the measure of a vertex angle

    So, Base angles = (3 × vertex angle) - 8

We know that sum of all angles of a triangle is 180° and the base angles of an isosceles triangle are equal.

∴ Base angles + vertex angle = 180°

  (3 × vertex angle) - 8  + x = 180°

  3x - 8 + x = 180°

  4x = 188°

  x = 47°

∴ The vertex angle is 47° and,

Base angles =  (3 × vertex angle) - 8  

                     = 3 × 47 - 8

                     = 141 - 8

                     = 133°

Assuming that costs increase linearly with the number of attendees, Patricia needs at least 30 people to attend the forum in order to break even.

Patricia needs 75 attendees to attend the forum in order to make a profit of 337,500.

By dividing the fixed costs by the contribution margin per unit, we are able to determine the break-even threshold in units. Divide the fixed costs by the contribution margin ratio to get the break-even threshold in dollars.

The percentage of the contribution margin to the sales revenue is known as the contribution margin ratio. Prior to the division operation, we add

the profit to the fixed cost in order to reach the goal profit.

Billing rate per participant = 10,000

Hotel charges per participant = 2,500

Contribution per participant = 7,500 (10,000 - 2,500)

225,000 is the fixed fee for the hotel room and amenities.

Break-even point in units = Contribution per unit – Fixed cost

= 30 individuals (225,000 -7,500)

Fixed cost plus profit minus contribution per unit equals break-even point in units with target profit.

Target profit = 337,500

= (225,000 + 337,500) ÷ 7,500

Mr. Henderson paid a total of $98.40 for phone service and $79.20 for garbage pickup last year. To find his average cost per month for these two services, we need to divide the total amount he paid by the number of months in a year.

Since there are 12 months in a year, we can divide the total amount Mr. Henderson paid for phone service and garbage pickup by 12 to find his average cost per month. This is calculated as follows:

Average cost per month = (98.40 + 79.20) / 12

Average cost per month = 177.60 / 12

Average cost per month = $14.80

Therefore, Mr. Henderson's average cost per month for phone service and garbage pickup last year was $14.80. This means that, on average, he paid about $14.80 per month for these two services.

The triangle dimensions are:  50, 27, and 7 cm

Step-by-step explanation:

The three sides of the triangle make up the entire perimeter.  Add each side and set the result equal to 84cm, the perimeter.

(7x+1) + (4x-1) + (14-x) = 84 cm

10x + 14 = 84

10x = 70

 x = 7 cm

Use x=7 to find the three dimensions:

1)  (7x+1) = 50 cm

2)  (4x-1) = 27 cm

3)  (14-x) = 7 cm

Do these add to 84 cm?

 (50+27+7) = 84 cm  YES
