Answer:
Correct answer not shown on the options.
y = -(1/2)+1
Step-by-step explanation:
Let's find an equation in the format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
The slope can be calculated as the Rise/Run of the line between the two given points (-6,4) and (-2,2):
Rise = (2 - 4) = -2
Run = (-2 - (-6)) = 4
Slope = Rise/Run = -2/4 or -(1/2)
In fact, the actual full equation is y= -(1/2)x+1 (See attached graph).
None of the options have a slope of -(1/2). Either the information on the two points or the options are incorrect.
Answer:
The cup can hold 235.5 cubic cm of popcorn.
Step-by-step explanation:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9 cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius (r)= 5 cm
Height (h)= 9 cm
= 3.14 (as per question).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Volume= r
h
3
Volume= 3.14 x 5 × 93
Volume= 3x14 x 25 x 3
Volume= 235.5 cubic cm.
Answer:
x ≈ 14.7
Step-by-step explanation:
Assuming the triangle is right then use Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 15² = 21²
x² + 225 = 441 ( subtract 225 from both sides )
x² = 216 ( take the square root of both sides )
x = 
≈ 14.7 ( to the nearest tenth )
Answer:
Comic Books
a: y=-10x+90
b: He will have 10 books at the end of the seventh day.
Step-by-step explanation:
A: Take two points. The y-intercept is (0,90). The graph decreases by 10 each day.
B: Look at day 8.
Answer:
52 inches
Step-by-step explanation:]
Step one:
given data
Length of one side= 10inch
Width of the other two sides= 21 inches
Step two:
The perimeter of the triangle is given as
P= L+W+W
P=10+21+21
P=52 inches
