Answer:
Anne = 9, Mark = 12, Sue = 15
Step-by-step explanation:
Total number of chocolates = 36
Sum of the ratio = 3 + 4 + 5 = 12
Number of chocolates Anne got :
[tex]= \frac{3}{12} \times 36 = 9[/tex]
Number of chocolates Mark got :
[tex]= \frac{4}{12} \times 36 = 12[/tex]
Number of chocolates Sue got :
[tex]= \frac{5}{12} \times 36 = 15[/tex]

Answer:
16 m
Step-by-step explanation:
The situation can be solved by proportion of corresponding sides in 2 right triangles.
let x be the length of shadow cast by oak tree, then
[tex]\frac{9}{12}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )
9x = 144 ( divide both sides by 9 )
x = 16
Length of shadow is 16 m
Describe how you would factor x^2 + 10x - 24. Be specific.
Answer:
if u have more doubts feel free to ask :)
Step-by-step explanation:
x² + 10x -24
x² + 12x - 2x - 24
x(x + 12) -2(x + 12)
(x + 12) (x - 2)
Factors of 24 : ±1 , ±2 , ±3 , ±4 , ±6 , ±8 , ±12, ±24. Combination of +12 and -2 gives "10" the middle term also " 24"
Which is true regarding chords and diameters of circles?
Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
Both chords and diameters have two endpoints on a circle. Chords must intersect the center of a circle.
Chords have two endpoints on a circle. Diameters have one endpoint on a circle and one at the center.
Chords have one endpoint on a circle and one at the center. Diameters have two endpoints on a circle.
The state that is valid is
"Every diameter of a circle is also a chord because a chord of a circle is any line segment joining two points on the circumference of the circle."
What is a diameterA diameter is a line that divides a circle into two halves, a diameter is also a chord
What is a ChordA chord is a line that connects points on a circle, a chord is not a diameter because it does not divide a circle into two equal halves

Kelly is going two work two part-time jobs during the school year. When she works for her dad, she will make $8.00 per hour. When she works at a day care center, she will make $14.00 per hour. To pay her car payment, Kelly needs to make at least $84.00 a week and can work no more than 10 hours total per week. Write an inequality to represent the difference combinations of hours working for her dad,X, and hours working for the daycare center,Y, Kelly can work if she wants to earn at least $84 per week
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of hours Kelly works for her dad per week and y represent the number of hours Kelly works in the daycare center per week.
Since she wants to make $84 per week, hence:
8x + 14y ≥ 84 (1)
Also, she can work a maximum of 10 hours per week, hence:
x + y ≤ 10 (2)

A regular hexagon has a perimeter of 150 m. Find its area. Leave your answer in the simplest radical form.
Answer:
1623.80 m²
√3(1875/2) m²
Step-by-step explanation:
The area, A of a regular hexagon can be obtained using the relation :
A = √3(p²/24)
The perimeter, p = 150 m
Therefore,
A = √3(150²/24)
A = √3(22500/24)
A = √3(937.5)
A = 1623.7976
A = 1623.80 m²
A = √3(1875/2) m²

Answer:

Step-by-step explanation:
First you reflect over the line y=x (line goes diagonal from quadrant I to quadrant III)
The rule of reflecting over the y=x line is that point (x,y) becomes point (y,x)
For example, point C ( -4, 2), becomes C' ( 2, -4)
Second is a translation 10 units to the right and 4 units up from C'(2,-4) to C''(0, 12)

It can't be A because counting by 5 starts with 1 not 12 it rotates clockwise not anti-clockwise. It can't be C because for it to be 50, it would need to be on the 10 not on 11.

for the equation y= x + 5, find the value of y when
(a)x= -2,
(b)x=0,
(c)x=2,
(d)x=4.
Answer:
a) 3 b) 5 c) 7 d) 9
Step-by-step explanation:
For this, you want to replace x in the equation y=x+5 with each of the values listed.
For the first one, -2, the equation becomes y=-2+5, which is solved to y=3.
For the second one, 0, the equation becomes y=0+5, which is solved to y=5.
For the third one, 2, the equation becomes y=2+5, which is solved to y=7.
For the last one, 4, the equation becomes y=4+5, which is solved to y=9.
