Answer:

Isosceles

Step-by-step explanation:

If BD is an altitude, it splits triangle ABC into 2 triangles.  It is also a median, so it splits the angle ABC into 2 congruent angles.  Angle ABD and CBD are congruent.  That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles.  Because of this, side AB and side CB are congruent.  That means that this is an isosceles triangle.

What is the perimeter of the triangle expressed as a polynomial? Length: 8x-2

Width: 9x-3
If you could show me how you got the complete answer I would really appreciate it.

Answers

The perimeter is the sum of the lengths of the three sides of the triangle. If "width" is the length of the 3rd side, then the perimeter is
  P = (8x-2) + (5x-4) + (9x-3)
  P = 8x + 5x + 9x -2 -4 -3
  P = (8+5+9)x -(2+4+3)
  P = 22x - 9

Josiah and his friends are going to the movies. Each ticket costs $10, and popcorn is $5 a bag. There is a $3 service fee for the entire purchase. He has $75. If he buys 4 tickets, how many bags of popcorn can he buy? if x=number of tickets and y=number of popcorn which of the following inequalities would you use to answer the problem?A x+y=75
B 10x+5y+3≤75
C 10x+5y≤75
D 10x+5y+3≥75

Answers

Answer:

B.

Step-by-step explanation:

If each ticket costs $10 and each popcorn costs $5, with x = number of tickets and y = number of popcorn and $3 the service we have

10x+5y+3 = total cost.

Now, he has a total of $75 and he buys 4 tickets so

10(4)+5y+3 = 75

40+5y+3 = 75

43+5y=75

5y = 75-43

5y = 32

y = 32/5 = 6.4 ≈ 6 popcorn.

Then, he can buy 6 popcorns. Now, to find the inequality we need to know that if he has $75, the total cost can't exceed $75, that is, the total cost needs to be less or equal to $75.

10x+5y+3 ≤75.

B
Because if x equals the number of tickets the it would be 10 X x. Same with the popcorn. for example: x=5 And y =3. it would be
10(5)+5(3)+3=$68

I just purchased a swimming pool with the dimensions of 15 feet across and 42 inches deep. Yes it is a circle. I need to know how many gallons of water it will hold. I am having a tanker brought out and need to know how much they need to bring because they charge by the gallon to bring it out.

Answers

When the pool is full to the rim, you'll have a cylinder of water.  The diameter
of the cylinder is 15-ft, and the height of the cylinder is 42 inches.

Here are the tools you'll need:

-- Volume of a cylinder = (pi) (radius squared) (height)
-- Radius = 1/2 diameter = 7.5 feet
-- Keep everything in the same units.  Depending on which unit
you prefer,  7.5 feet = 90 inches,  and 42 inches = 3.5 feet.

I like inches and cubic inches, because I remember that
1 gallon = exactly 231 cubic inches.

Volume of the cylinder = (pi) (radius squared) (height)

Volume = (pi) (90 squared) (42) = (pi) (8,100) (42) = 1,068,769.8 cubic inches

1,068,769.8 / 231 = 4,626.7 gallons
===================================
Slightly easier:

about 7.48 gallons = 1 cubic foot

Volume = (pi) (7.5-ft squared) (3.5-ft) = 618.5 cubic feet

(618.6 cubic-ft) x (7.48 gallons per cubic-ft) = 4,627.1 gallons

The results are not identical, but don't panic.  They are equal
to within about 51 ounces (0.009 percent).  The tanker will either
spill or evaporate more than that during the process of the delivery.

By the way ... you'd be wise not to install the pool on the second floor.
That much water weighs a little over 19.3 tons !

In a refrigerator, there are 6 bottles of soft drinks (each a different brand) and 8 cans of juice (each a different type). How many combinations can be made with one soft drink and one fruit drink?a. 1
c. 36
b. 14
d. 48

Answers

The number of ways of choosing 1 soft drink from 6 soft drinks is 6C1 = 6!/((6-1)! * 1!) = 6!/(5!) = (6*5*4*3*2*1)/(5*4*3*2*1) = 6.

Similarly, the number of ways of choosing 1 fruit juice from 8 cans of juice is 8C1 = 8!/((8-1)! * 1!) = 8!/7! = 8

number of combinations of 1 soft drink AND 1 fruit drink = 6 x 8 = 48

Which function could be represented by the graph on the coordinate plane?

Answers


Since no function can be seen in this question, it may describe overall -the slope. The slope is the direction and magnitude of a relationship in the given graph. It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation.
