You want to know how many of the students at your school eat lunch everyday. Of the 3545 students you randomly ask 300. 220 say yes, 70 say no and 10 don't know. Based on your survey what is the best estimate of the number of students who eat lunch everyday?
a.) 3300
b.) 2600
c.) 827
d.) 1500
(no links please!)
Answer:
B) 2600
Step-by-step explanation:
Set up a proportional equation and solve:
220/300=x/3545
(220)(3545)=300x
779900=300x
2599.666=x
2600=x
Your best estimate is B) 2600

Ellie is interested in getting a new phone. One phone company, phone 1 charges a monthly fee of 6$. They also charge 0.10$ per minute. Another company, phone 2, charges 5$ for a monthly fee and 0.25$ per minute. Write an equation for the total cost of each phone bill, where y is the total cost and x is the total number of minutes on the phone. Which company will allow Ellie to talk the longest is she only wants to spend 22$ a month
Answer:
Phone 1 will allow Ellie to talk the longest
Step-by-step explanation:
Phone 1:
(0.10x) + 6 = y
(0.10x) + 6 - 6 = 22 - 6
0.10/0.10x = 16/0.10
x = 160 minutes
Phone 2:
(0.25x) + 5 = y
(0.25x) + 5 - 5 = 22 - 5
0.25/0.25x = 17/0.25
x = 68 minutes

Write an equation in slope-intercept form of the line that passes through the given point and is
parallel to the graph of the given equation.
(-1,6); y = 9x - 5
Answer:
y = 9x - 15
Step-by-step explanation:
The given y = 9x - 5 is already in slope-intercept form. Any line parallel to this one has an equation that looks exactly the same except for the constant term. Call the new constant term 'C.'
Start with y = 9x - 5 and substitute the coordinates of the given point (-1, 6):
6 = 9(-1) + C, or
6 + 9 = C, or
C = 15
Then the equation of the line that passes through (-1, 6) and is parallel to y = 9x - 5 is
y = 9x - 15

The area of the sector is 100 units².
The area of the sector is more than half of the circle’s area.
Answer:

Step-by-step explanation:
just took the edge.
The area of the sector is 250 units². Therefore, the correct option is option A among all the given options.
What is sector of circle?A circle's sector is a pie-shaped portion made up of the arc and its two radii. At both ends of the arc, when a section of the circle's circumference (also called as an arc) and two of its radii meet, a sector is produced. A sector of such a circle resembles a piece of pizza or a pie in shape.
A circle ranks among the most ideal shapes in geometry. The simplest geometric shape is that of a circle's sector. It has a number of its own components. such as sector, segmentation, circumference, segment, and diameter. The area of the sector is 250 units².
Therefore, the correct option is option A.

y = [tex]\frac{-5}{4}[/tex]x + 3
Step-by-step explanation:As shown in the graph, the line is a straight line. Therefore, the general equation of a straight line can be employed to derive the equation of the line.
The general equation of a straight line is given by:
y = mx + c or -------------(i)
y - y₁ = m(x - x₁) -----------------(ii)
Where;
y₁ is the value of a point on the y-axis
x₁ is the value of the same point on the x-axis
m is the slope of the line
c is the y-intercept of the line.
Equation (i) is the slope-intercept form of a line
Steps:
(i) Pick any two points (x₁, y₁) and (x₂, y₂) on the line.
In this case, let;
(x₁, y₁) = (0, 3)
(x₂, y₂) = (4, -2)
(ii) With the chosen points, calculate the slope m given by;
m = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]
m = [tex]\frac{-2-3}{4-0}[/tex]
m = [tex]\frac{-5}{4}[/tex]
(iii) Substitute the first point (x₁, y₁) = (0, 3) and m = [tex]\frac{-5}{4}[/tex] into equation (ii) as follows;
y - 3 = [tex]\frac{-5}{4}[/tex](x - 0)
(iv) Solve for y from (iii)
y - 3 = [tex]\frac{-5}{4}[/tex]x
y = [tex]\frac{-5}{4}[/tex]x + 3 [This is the slope intercept form of the line]
Where the slope is [tex]\frac{-5}{4}[/tex] and the intercept is 3
Ms. Geiger made 100 cupcakes. 60/100 were chocolate, 2/10 were vanilla, and the rest were red velvet. What fraction of the cupcakes were red velvet?
Answer:
2/10
Step-by-step explanation:
Ms. Geiger made 100 cupcakes.
a) Number of chocolate
60/100 were chocolate
= 60/100 × 100 = 60 chocolate cup cakes
b) Number of vanilla
2/10 were vanilla
Hence:
2/10 × 100 = 20 vanilla cup cakes
c) the rest were red velvet.
Number rod red velvet = 100 - (60 + 20)
= 100 - 80
= 20 velvet cupcakes
What fraction of the cupcakes were red velvet?
Converting to fraction
Number of velvet cupcakes/Total number of cakes
= 20/100
= 2/10

Answer:
75.4m²
Step-by-step explanation:
The shape shown is a cylinder
The volume of a cylinder can be calculated using this formula:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
The cylinder shown has a radius of 2m and a height of 6m
Using this information we plug in the values into the formula
[tex]V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822[/tex]
So the area of the cylinder is 75.39822
Our final step is to round to the nearest hundredth
The final answer would be 75.4m²
