Mathematics
1 answer:

3 0

Answer:

C. y = ½x + 4

Step-by-step explanation:

Equation for a line in slope-intercept form is given as y = mx + b

So, we need to find the slope (m) and the y-intercept (b) of the line given.

m = ∆y/∆x

Using two points on the line, (0, 4) and (-2, 3),

Slope (m) = (3 - 4)/(-2 - 0)

m = -1/-2

m = ½

y-intercept (b) = 4, this is where the line intercepts the y-axis.

To write the equation, substitute m = ½ and b = 4 into y = mx + b

Thus:

y = ½x + 4

A 14 inch pizza (diameter is 14) was cut in to 8 pieces. What is the angle measure of each slice? *
Luda [366]

Answer:

The angle for each slice is 45 degrees.

Step-by-step explanation:

In order to calculate the angle of each slice, we first need to calculate the total area of the pizza, because we will use that to find the area of each slice and as a result it's angle. To calculate the area of the pizza we must use:

pizza area = pi*r²

r = d / 2 = 14 /2 = 7 inches

pizza area = pi*(7)² = 153.86 square inches

Since the pizza was divided in 8 pieces, the area of each piece is given by the area of the pizza divided by the number of slices. We have:

slice area = pizza area  / 8 = 153.86 / 8 =19.2325 square inches

Each slice is a circle sector, therefore it's area is given by:

slice area = (angle*pi*r²)/360

Therefore we can solve for angle:

19.2325 = (angle*pi*7²)/360

angle*pi*49 = 6923.7

angle = 6923.7 / pi*49 = 45 degrees

The angle for each slice is 45 degrees.

George is throwing a party for his son's 9th birthday he orders for sandwiches to the party if each person will eat 2/3 of a san
ddd [48]

Answer:

George can feed 6 people.

Step-by-step explanation:

Given:

Number of sandwiches = 4

Each person eats two-third of a sandwich.

Therefore, number of persons eating 4 sandwich is given as:

\textrm{Number of persons} =\frac{\textrm{Total sandwiches eaten}}{\textrm{Total sandwiches eaten by 1 person}}

Therefore,

\textrm{Number of persons} = \frac{4}{\frac{2}{3}}\\\\\textrm{Number of persons} =4\times \frac{3}{2}=6
