Answer: y=14
Step-by-step explanation: y is directly proportional to x, meaning that multiplying x by a certain factor would also multiply y by that same factor. x=5 and y=7. If x changes to 10, it means that x is multiplied by a factor of (10/5) = 2. Therefore, y is multiplied by this same factor (2). As a result, 7*2=14
The area of a room is 425 square feet. The length is (x+9) feet and the width is (x+1) feet. Find the dimensions of the room.
Answer:
width is 17
length is 25
Step-by-step explanation:
(x+9)(x+1) =[tex]x^{2}[/tex] + 10x + 9 = 425
[tex]x^{2}[/tex] + 10x - 416 = 0
(x-16)(x + 26) = 0
x = 16 or x = -26
x cannot be -26
x = 16
so, (16 + 1) = 17
(16 + 9) = 25

the ravens scored 1 touchdown and an extra point . how many total points did they score
What fraction does point S represent?
Answer:
C
Step-by-step explanation:
So what you gotta do is count the lines. You don't count the one with one on it, but you count all the way through to 2. That gets you eight, so each line is 1/8. 1-2 in 1/8 intervals. 1 1/4 multiply 2 on the numerator and denominator gets 1 2/8, 1 1/2 multiply 4 on the numerator and denominator gets you 1 4/8. Counting the lines, each of those matches up. The first interval is 1 1/8.

Find the volume of the cylinder. Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi radius 5 height 6
Answer:
150π cu. units
Step-by-step explanation:
V = Bh where B is the area of the circular base and h is the distance between the bases (height)
B = [tex]\pi r^{2}[/tex] = [tex]\pi 5^{2}[/tex] = 25π
V = 25π(6) = 150π cu. units
Answer: V = 471 m^3
In terms of PI - V = 150 π m^3
Step-by-step explanation:
V = πr2h
V = 3.14(5)^2(6)
V = 3.14(25)(6)
V = 471 M^3
or
V = 3.14 (25)(6)
V = 150 π m^3

You need to get graphing paper
Answer:
This quadrilateral is a parallelogram because the slopes of the opposite sides equal eachother.
Step-by-step explanation:
To prove this quadrilateral is a parallelogram you want to show that the opposite sides are parallel by finding the slopes of each. Which means the parallel lines have to have the same slopes if it is a parallelogram.
To find slope we use M= Y1-Y2/X1-X2
Lets start with A and B
M=7-8/2-(-2)
so M= -1/4 for Line AB
Now lets find C and D
M=2-1/1-5
so M=-1/4 for line CD
So this quadrilateral is a parallelogram because the slopes of the opposite sides equal eachother.

The band had 20 members last year and 25 members this year.
How many girls and how many boys are in the band in each of these two years?
Last year: 8 boys and 12 girls. This year: 10 boys and 15 girls.
Last year: 12 boys and 8 girls. This year 13 boys and 12 girls
O
Last year: 8 boys and 12 girls. This year: 12 boys and 13 girls.
Last year: 12 boys and 8 girls. This year 15 boys and 10 girls
Answer:
last year 8 boys 12 girls and this year 10 boys 15 girls
Step-by-step explanation:
ratio = 4:6
total ratio = 6 +4 =10
last year
ratio 1 = 20 ÷ 10 = 2
boys = 2 × 4 = 8
girl = 2 × 6 = 12
this year
ratio 1 = 25 ÷ 10 = 2.5
boys = 2.5 × 4= 10
girls = 2.5 × 6 = 15

Finit set:
1+2+3+........+25=??
Answer:
Finite set: A set is said to be a finite set if it is either void set or the process of counting of elements surely comes to an end is called a finite set.
In a finite set the element can be listed if it has a limited i.e. countable by natural number 1, 2, 3, ……… and the process of listing terminates at a certain natural number N.
The number of distinct elements counted in a finite set S is denoted by n(S). The number of elements of a finite set A is called the order or cardinal number of a set A and is symbolically denoted by n(A).
Thus, if the set A be that of the English alphabets, then n(A) = 26: For, it contains 26 elements in it. Again if the set A be the vowels of the English alphabets i.e. A = {a, e, i, o, u} then n(A) = 5.

What is the area of the figure below?
3 in.
3 in.
5 in.
5 in.
3 in.
3 in.
7 in.
Answer:
68 inches squared
Step-by-step explanation:
First, let's find the area of the squares at the top and bottom. Area for a square is:
L * W = A
Plug in the values...
3 * 3 = 9
Therefore, the area of the two squares combined is 18 inches (since 9 + 9 = 18). Now, the hexagon in the middle, which is the hardest part. We will have to separate it into 4 triangles and a rectangle, for simplification. We need to find the base widths of the triangles, which are:
7 (total width) - 3 (middle width) / 2 (because there are two sides)
So it is:
(7 - 3)/2
4/2 = 2
So, the base of the triangle is two inches. We also know that the height of the triangle is five inches. The formula for the area of a triangle is:
(B * H)/2 = A
Fill it in...
(2 * 5)/2
10/2 = 5 inches
So, the area of each triangle is 5 inches. Since there are four triangles, we need to do:
5 * 4 = 20 inches
That means that all of the triangles combined is 20 inches. Lastly, we need the middle part of our hexagon. It is 10 inches tall, and three inches wide. So...
L * W = A
10 * 3 = 30
So, that means that the area of the hexagon is:
30 + 20 = 50
Plus, the two squares from the beginning:
50 + 18 = 68 inches squared
Therefore, the area of the figure is 68 inches. Hope this helps you!

What is the surface area of the cylinder with height 4 mi and radius 3 mi? Round your answer to the nearest thousandth.
Answer:
The surface area of the cylinder will be "131.88".
Step-by-step explanation:
The given values are:
Height of cylinder,
h = 4 m
Radius of cylinder,
r = 3 m
As we know,
The surface are of cylinder is:
⇒ [tex]A_s=2 \pi r(h+r)[/tex]
On substituting the values, we get
⇒ [tex]=2\times 3.14\times 3(4+3)[/tex]
⇒ [tex]=18.84\times 7[/tex]
⇒ [tex]=131.88[/tex]

PLEASE HELPPPPPPP WILL GIVE BRAINLIEST
Answer:
y-intercept:
(0,2) or just -3/5
Step-by-step explanation:
Answer:
3x + 5y = 2
Step-by-step explanation:
y = -3/5 x + 2
multiply both sides by 5
5y = -3x + 2
add 3x to both sides
3x + 5y = 2
note: if it really has to be equal to 20, then multiply both sides by 10, which will result in 30x + 50y = 20

Find the solution to the following: *
Enter your solution in the following format x = solution. (Ex: x = 5)
8x+10=2(4x+5)
Find the solution to the following: *
Enter your solution in the following format x = solution. (Ex: x = 5)
3x-8=2(x-4)
Answer:
First one: x = all real numbers
Second one: x = 0
Step-by-step explanation:
for the first one
given 8x+10=2(4x+5) we need to isolate the variable (x) using inverse operations
step 1 distribute the 2 to what is in the parenthesis ( 4x and 5 )
2 * 4x = 8x
5 * 2 = 10
now we have 8x + 10 = 8x + 10
step 2 subtract 8x from each side
8x - 8x = 0
8x - 8x = 0
now we have 10 = 10
subtract 10 from each side
10 - 10 = 0
10 - 10 = 0
we're left with 0 = 0 meaning that all real numbers are solutions
For the second one
given 3x-8=2(x-4) once again we need to isolate the variable using inverse operations
step 1 distribute the 2 to what is in the parenthesis (x - 4)
2 *x = 2x
2 * -4 = -8
now we have 3x - 8 = 2x - 8
step 2 add 8 to each side
-8 + 8 = 0
-8 + 8 = 0
now we have 2x = 3x
step 3 subtract 2x from each side
3x - 2x = x
2x - 2x = 0
we're left with x = 0
