Answer:
total cup = 32
1 student = 1/2 cup
find remaining cup = y
*we don't know how many students are there, so we just let it be x .
remaining cup = total cup - cup drank by students
y = 32 - 1/2x
y = -1/2x + 32 ( option c )
why 1/2x ? because we don't know how many students drank the juice, so we just let it be x .

1. An arch in the shape of a semicircle is to be set up at the entrance of a festival.
The distance around the arch is about 110 feet. What is the height of the arch, in
feet? Round your answer to the nearest whole number.
Answer:
35 ft
Step-by-step explanation:
The arch is in the shape of a semicircle.
The distance around the arch is about 110 feet. This is the same as the circumference of the arch.
The height of the arch is the radius of the arch.
The circumference of a semicircle is given as:
[tex]C = \pi r[/tex]
where r = radius
Therefore:
110 = πr
=> r = 110/π
r = 35.01 ft ≅ 35 ft
The height of the arch is 35 ft
The height of the arch in feet is 35 ft.
Calculation of the height:Since The distance around the arch is about 110 feet.
We know that
The circumference of a semicircle should be
110 = πr
[tex]r = 110/\pi[/tex]
r = 35.01 ft
≅ 35 ft
hence, we can conclude that The height of the arch in feet is 35 ft.

angles M and N are supplementary find angle M if angle N=27
Answer:
153°
Step-by-step explanation:
Supplementary = 180 degrees
180 - 27 = 153 degrees
Answer:
153 degrees
Step-by-step explanation:
When two angles are supplementary, their angle measures must add up to 180 degrees. Therefore:
M+N=180
M+27=180
M=180-27=153

convert 55/100 to a decimal, please
Answer:0.55
Step-by-step explanation:
OK decimal means one number before (.) (point)
for example if question is
1.) 55/10 = ans: 5.5 (here before . (point) 5 is there only one number
2.)55/1000= ans: 0.055(here before .(point) 0 is there only one number
3.)like ur question 55/100= 0.55 ☻
Answer: 0.55
Step-by-step explanation:
Because 55/100 is 55% and 55% in decimal form is .55. Always move the decimal to the right when the percentage is under 100%.
What is the area of trapezoid QRST?
Answer:
?
Step-by-step explanation:
divide the trapezoid into 1 square and 2 triangles.
then calculate the square.
6 * 6 = 36.
after youve done this you have to calculate the triangles.
6 * 3 = 18 = 1 triangle
18 * 2 = 36 = 2 triangles
now add them together:
36 + 36 = 72
in conclusion this should be the proper answer but its not on your page so...
i would say count the squares 1 by one...
but i did that...
its 54

Answer:
Answer number one, x < 7/12
Answer:
A
Step-by-step explanation:
If you make he denominators equal to each other (in this case 12) the new fractions would be 3/12 and 10/12. Then you would subtract 3/12 from both sides making 7/12 on the right side. The inequality remains facing the same direction, making the answer A or x<7/12.

Find the mean of the following group of numbers: 1.2, 2.3, 0.8, 2.3, 1.0, 3.1,
4.2, 1.4, 2.1, 0.4, 1.3, 2.0, 1.8, 3.2*
Answer:
1.93
Step-by-step explanation:
1.To find the mean you need to add all the numbers
2. Next divide by how many numbers they are
Example:
1,2,3,4
1. Add the numbers together
(1+2+3+4=10)
2. Divide by how many numbers they are
(There are only 4 numbers)
So..... 10 ÷4 =2.5
So 2.5 is the mean
what is the sum of a and b?
Answer:
a=13, b=7
Step-by-step explanation:
You can use the exponent rule
[tex]3x^{a-5}y^{9-b}=3x^{8}y^{2}[/tex]
so [tex]x^{a-5}=x^{8}[/tex] so
a-5=8
a=13
[tex]y^{9-b} =y^{2}[/tex] so
9-b=2
b=7

Answer:
16:24 is the answer
Hope it helps:)
Step-by-step explanation:
The initial number of cards were
1x:1x
(Equal red cards and black cards)
So, total of 48 and..
24 red cards
24 black cards
Now, since 8 red cards are removed we have,
24-8= 16 red cards
and 24 black cards
So the ratio of red to black is--
16:24
= 2:3 ( i divided both with 8 to simplify )
Pack 48 48/2 =24
Red= 24 24/24 : 24 / 24
Black = 24 1:1
----------------------------------------------------------------
Pack 48 48/2 = 24
Red= 16 24 / 16 : 24 / 24
Black= 24 1,5 : 1
There's 1,5 black cards for each red card

Answer:
X = - 6
Step-by-step explanation:
18x + 30 = 6(2x – 1)
Multiply 6 to 2x and - 1
18x + 30 = 12x – 6
Subtract 30 on both sides
18x = 12x – 36
Subtract 12x on both sides
6x = - 36
Divide by 6 on both sides
X = - 6
Lines l and m are parallel.
Use the diagram to determine the measure of ∠3.
Answer:
∠3 is 70°
Step-by-step explanation:
∠1 is 50° since it is across from another 50° angle
and then you use the equation x+25+2x+50=180 to find x
x then equals 35°
you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°
Answer:
It is 70
