which of the following describes the percentage of the students in your class who are
women with brown hair?
(a) (40%) (50%) = 20%
(b) 50% - 40% = 10%
(c) 40% + 50% = 90%

Answer:

So 61.5 inches I'm guessing in feet would be 5.125 feet. You just divide 61.5 by 12 to get your answer.

Step-by-step explanation:

Answer:

a. corresponding angles

b. alternate interior angles

c. opposite angles

d. cointerior angles

a. = 127

b. = 65

c. = 179

d. 180-41= 139

Answer: 3.285?

I just multiplied 1.5 and 1.19, then added the product and his height at the age of 12 so, therefore i got 3.285 as a answer

B)27 miles per hour

Step-by-step explanation:

HERE IS THE COMPLETE QUESTION

boat on a river travels downstream between two points, 90 mi apart, in 1 h. The return trip against the current takes 2 1 2 h. What is the boat's speed (in still water)??b) How fast does the current in the river flow?

Let the speed of boat in still water = V(boat)

speed of current=V(current)

To calculate speed of boat downstream, we add speed of boat in still water and speed of current. This can be expressed as

[V(boat) +V(current)]

It was stated that it takes 1hour for the

boat to travels between two points of 90 mi apart downstream.

To calculate speed of boat against current, we will substact speed of current from speed of boat in still water. This can be expressed as

[V(boat) - V(current)]

and it was stated that it takes 2 1/2 for return trip against the Current

But we know but Speed= distance/time

Then if we input the stated values we have

V(boat) + V(current)]= 90/1 ---------eqn(1)

V(boat) - V(current) = 90/2.5----------eqn(2)

Adding the equations we have

V(boat) + V(current) + [V(boat) - V(current)]= 90/2.5 + 90/1

V(boat) + V(current) + V(boat) - V(current)]=90+36

2V(boat)= 126

V(boat)=63miles per hour.

Hence, Therefore, the speed of boat in still water is 63 miles per hour.

?b) How fast does the current in the river flow?

the speed of the current in the river, we can be calculated if we input V(boat)=63miles per hour. Into eqn(1)

V(boat) + V(current)]= 90/1

63+V(current)=90

V(current)= 27 miles per hour

Hence,Therefore, the speed of current is 27 miles per hour.

Answer: True

Step-by-step explanation: Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length. The concept of a median extends to tetrahedra.

Answer:

True

Step-by-step explanation:

The constant of proportionality is 4, and the relationship is given by s = 4h.

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let h represent the number of hours and s represent the number of inches of snow on the ground. Since both variables are proportional, hence:

s = hk; where k is the constant of proportionality

Let us assume in the table, when h = 1, s = 4 hence:

s = hk

4 = k(1)

k = 3

s = 4h

The constant of proportionality is 4, and the relationship is given by s = 4h.

Answer:

x = 7

Step-by-step explanation:

∠CAD is a right angle, right angles has 90° measurement.

m∠DAB = 7x - 4 AB bisects ∠CAD this means it divides the angle into two equal parts.

So it's safe to write the following equation:

7x - 4 = 45 (half of 90°)

add 4 to bot sides

7x = 49 divide both sides by 7

x = 7

Answer:

36 ft

Step-by-step explanation:

6/x=7.5/45

270=7.5x

x=36

In this exercise we have to have knowledge of triangles, so we can use the theory of similar triangles to find the value of X, like:
