There are 1,000ml in a liter. There are 2 liters, so you originally had 2,000ml. You use 100, so you have 1,900ml left. Divide 1,900 by 400.
1900/400=4.75
We can round down, for a whole number.
So you can make 4 milkshakes with some milk left over for some pudding for me

the sides of a triangle measure 6 inches 8 inches and 1o inches the triangle one 90 degree angle what type of triangle is it
Answer:
a right triangle
Step-by-step explanation:
as long a a triangle has one angle of 90 degrees, then it is a right triangle. An acute triangle has to have an angle less than 90 degrees, and an obtuse angle has to have an angle greater than 90 degrees.

The coach of a softball team has 8 good hitters and 9 poor hitters. He chooses 5 hitters at random.In how many ways can he choose 4 good hitters and 1 poor hitter?
Answer:
He can choose 4 good hitters and 1 poor hitter in 630 different ways.
Step-by-step explanation:
The order in which the hitters are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In how many ways can he choose 4 good hitters and 1 poor hitter?
4 good hitters from a set of 8.
1 poor hitter from a set of 9. So
[tex]T = C_{8,4}*C_{9,1} = \frac{8!}{4!(8-4)!}*9 = 630[/tex]
He can choose 4 good hitters and 1 poor hitter in 630 different ways.
A semicircle with diameter 3.5m. Find the perimeter if the semicircle. Take pi = 3.14
Step-by-step explanation:
perimeter is (pi×diameter)/2
perimeter =(3.14×3.5)/2
perimeter =5.49m
If x = 5 units, y = 6 units, and h = 6 units, find the area of the trapezoid shown above using decomposition. A. 102 square units B. 30 square units C. 66 square units D. 48 square units
Answer:
C. 66 square units
Step-by-step explanation:
The area of the middle rectangle would by base × height, or y × h, or 6 × 6.
The area is 36.
The area for one triangle would 1/2 × base × height.
(But since there are two triangles to solve for, the 1/2 is not necessary, and we can just do base × height again.)
So, it would be x × h, or 5 × 6.
The area is 30.
Combine both areas to get the whole area of 66 units²
graph the line whose y-intercept is -7 and whose x-intercept is 1
Answer:
[tex]y=7x -7[/tex]
Step-by-step explanation:
We are given two points, the y - intercept and the x - intercept.
The y - intercept being: ( 0, -7 )
The x - intercept being: ( 1, 0 )
The equation of a line in slope - intercept form is:
y = mx + b, where m is the slope and b is the y - intercept.
We already have the y - intercept. So far we have:
y = mx - 7
What we're missing is the slope.
To find the slope, we can use this formula:
[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex], where [tex]x_{2}[/tex] and [tex]x_{1}[/tex] are the x - coordinates of both points and [tex]y_{2}[/tex] and [tex]x_{1}[/tex] are the y - coordinates of both points.
[tex]m=\frac{0-(-7)}{1-0} \\\\m=\frac{7}{1}\\m=7[/tex]
We now have the missing piece, the slope, so the equation now is:
[tex]y=7x -7[/tex]

I got the answer 0.007853982 inches sq, but it says it’s not correct, what am I doing wrong?
Answer:
Area of pupil = 0.007855 square inch.
Step-by-step explanation:
Given the following data;
Diameter = 0.1 inch
To find the area of the pupil (circle);
Area of circle = π(D/2)²
Area of pupil = 3.142*(0.1/2)²
Area of pupil = 3.142*(0.05)²
Area of pupil = 3.142*0.0025
Area of pupil = 0.007855 square inch.
Today, everything at a store is on sale. The store offers a 20% discount.
If the regular price of an item is x dollars, what is the discount price in dollars?
0.8x or x-0.2x
0.9x
0.7x
0.6
Answer:
0.8x or 0.2x
Step-by-step explanation:
20% of x = 20/100 × x = 0.2x
So discount price = x - 0.2x = 0.8x

A wall of a building is made from blocks that are each 1 cubic foot. The wall is 6 feet high and 6 feet wide. A window is made by removing some blocks as shown below. The window is 2 feet high by 2 feet wide. Suppose the wall is expanded to be 12 feet high by 12 feet wide, and the window is expanded to be 4 feet high by 4 feet wide. How will this change the volume of the wall?
Answer:
This will increase the volume of the wall by 104 cubic feet
This will increase the volume of the wall by 104 cubic feet

The scale factor of the dimensions of two similar wood floors is 4:3. It costs $207 to refinish the smaller wood floor. At that rate, how much would it cost to refinish the larger wood floor? $
Answer:
$276
Step-by-step explanation:
Create a proportion where x is the cost to refinish the larger wood floor:
[tex]\frac{4}{3}[/tex] = [tex]\frac{x}{207}[/tex]
Cross multiply and solve for x:
3x = 828
x = 276
So, to refinish the larger wood floor, it would cost $276
