<span>the answer is A, because there are 10 total students (7+3) and there are 7 girls in the class making it a 7:10 ratio.</span>
There are 5 equal sections on a spinner. Buzz wants to try to get the Letter D, which is 1/5 of the equal sectioned spinners.
In a 6 sided cube, 2, 4, & 6, are the even numbers, or 3/6 or 1/2 of the numbers are even.
Multiply the two fractions together:
1/5 x 1/2 = 1/10
C) 1/10 is your answer
hope this helps
Answer:
x = -30 so it's D
Step-by-step explanation:
Answer:
The required equation is:
Step-by-step explanation:
To find the equation of a line, the slope and y-intercept is required.
The slope can be found by finding the slope of given line segment. A the perpendicular bisector of a line is perpendicular to the given line, the product of their slopes will be -1 and it will pass through the mid-point of given line segment.
Given points are:
We will find the slope of given line segment first
Let m_1 be the slope of perpendicular bisector then,
Now the mid-point
We have to find equation of a line with slope -3/2 passing through (2,6)
The equation of line in slope-intercept form is given by:
Putting the value of slope
Putting the point (2,6) to find the y-intercept
The equation is:

Answer:
a) ∆ABC ~ ∆EDC by AA similarity
b) ED/AB = 3/4
c) 15 cm
Step-by-step explanation:
a) Two angles in each triangle are the same, so the AA similarity postulate can be used to declare the ∆ABC ~ ∆EDC. (Each triangle includes a right angle and angle C.)
__
b) Corresponding sides are ED/AB, DC/BC, EC/AC. The ratio of corresponding sides is ED/BC = (12 cm)/(16 cm) = 3/4.
__
c) Using the ratios identified above, we have ...
DC/BC = 3/4 = x/(20 cm)
x = 3/4(20 cm)
x = 15 cm
