Ms. Durand has an obsession with Christmas. She is standing 8ft away from a 20ft Christmas Geometree. She wonders, "hmmm, what is the angle of elevation from myself to the star on the top of the tree?"
Answers
Answer:
68.20°
Step-by-step explanation:
Using Pythagoras rule :
Tanθ = opposite / adjacent
Adjacent = 8ft
Opposite = 20
Tanθ = 20 / 8
θ = tan^-1(20/8)
= 68.198590
Hence, angle of elevation = 68.2°

Answer: 5.81%
Step-by-step explanation: Delta Math
A = 17700. P = 9900. t = 10
17700 = 9900e^r(10)
17700/9900 = 9900e^10r/9900
1.7878788 = e^10r
In(1.7878788) = In(e^10r)
In(1.7878788) = 10r
In(1.7878788)/10 = 10r/10
0.058103 = r
5.8103% = r
r = 5.81%

60 children go to a nursery. The ratio of girls to boys is 3 : 2
The children go to the nursery either in the morning or in the afternoon.
Three quarters of the children go to the nursery in the morning.
The rest of the children go to the nursery in the afternoon.
7 boys go to the nursery in the afternoon.
Work out how many girls go to the nursery in the morning.
Answers
Answer:
Girls (Morning) = 16
Step-by-step explanation:
60 children go to a nursery. The ratio of girls to boys is 3 : 2
Number of Boys = 3 / (3 + 2) * 60 = 3/5 * 60 =36
Number of Girls = 2 / (3 + 2) * 60 = 2/5 * 60 = 24
Three quarters of the children go to the nursery in the morning.
Number of children (Boys + Girls) = 3/4 * 60 = 45
The rest of the children go to the nursery in the afternoon.
Number of children (Boys + Girls) = 60 - 45 = 15
7 boys go to the nursery in the afternoon.
Boys + Girls = 15
Girls (Afternoon) = 15 - Boys = 15 - 7 = 8
Work out how many girls go to the nursery in the morning.
Girls (Morning) + Girls (Afternoon) = Girls (Total)
Girls (Morning) + 8 = 24
Girls (Morning) = 24 - 8
Girls (Morning) = 16
Answer:
The number of girls that go to the nursery in the morning are 28 girls
Step-by-step explanation:
The question is a word problem and the parameter given are as follows;
The number of children that go to the nursery, n = 60
The ratio of girls to boys = 3 : 2
The number of periods the children can attend the nursery = 2, morning or afternoon
The proportion of the children that go to the nursery in the morning = 3/4
The proportion of the children that go to the nursery in the afternoon = All those that do not go in the morning
The number of boys that go to the nursery in the afternoon = 7 boys
Let, 'x', represent the number of girls in the school, and let 'y', represent the number of boys in the school
Therefore, we have the following possible equations;
x + y = 60
x:y = 3:2
Therefore, the proportion of the total number of children that go to the nursery that are girls, x = 3/(3 + 2) = 3/5
The number of girls that go to the nursery, x = n × 3/5 = 60 × 3/5 = 36 girls
The number of girls that go to the nursery, x = 36 girls
∴ The number of boys that go to the nursery, y = 60 - 36 = 24 boys
The number of boys that go in the morning = y - (The number of boys that go to the nursery in the afternoon)
∴ The number of boys that go in the morning = 24 boys - 7 boys = 17 boys
The total number of children that go to nursery in the morning = 3/4 × (The number of children that go to the nursery, n)
∴ The total number of children that go to nursery in the morning = 3/4 × 60 = 45 children
The number of girls that go to the nursery in the morning = (The total number of children that go to nursery in the morning) - (The number of boys that go in the morning)
Therefore, the number of girls that go to the nursery in the morning = 45 children (girls + boys) - 17 boys = 28 girls
The number of girls that go to the nursery in the morning = 28 girls

Answers
Answer:2
Step-by-step explanation:
2
For line y = 9x, m = 9 and c = 0
What is the slope-intercept form of the line?"y = mx + c, where m is the slope of the line and c is the y-intercept of the line."
What is slope of the line?"It is the change in y coordinate with respect to the change in x coordinate."
What is y-intercept?"It is a point at which a line intersects the Y-axis."
For given question,
We have been given an equation of line y = 9x
By comparing above equation of line with the slope-intercept form of line,
m = 9 and c = 0
This means the slope of the line y = 9x is 9 and the y-intercept is 0
Therefore, for line y = 9x, m = 9 and c = 0
