Step-by-step explanation:
[tex]\frac{25}{12} :\frac{y}{100}[/tex]
12 · y = 25 · 100
12y = 2500
12y ÷ 12 = 2500 ÷ 12
[tex]y=208\frac{1}{3}[/tex]

Please help me solve this
Answer:
x=38
Step-by-step explanation:
First, know that the sum of the angles in a triangle is 180.
Then, add the angles. 2x+38+x+x-10.
Make them equal to 180.
2x+38+x+x-10=180
Simplify.
4x+28=180
Subtract 28 from 180.
4x=152
Divide 4 from 152 to make x alone.
x=38
There you go!

P( Work | Senior) = [?]
Round to the nearest hundredth.
Answer:
[tex]P(Work | Senior) = 0.14[/tex]
Step-by-step explanation:
Given
The attached table
Required
[tex]P(Work | Senior)[/tex]
This is calculated using:
[tex]P(Work | Senior) = \frac{P(Work \ n\ Senior)}{P(Senior)}[/tex]
This gives:
[tex]P(Work | Senior) = \frac{n(Work \ n\ Senior)}{n(Senior)}[/tex]
From the table:
[tex]n(Work \ n\ Senior) = 5[/tex]
[tex]n(Senior) = 25 + 5+ 5 = 35[/tex]
So:
[tex]P(Work | Senior) = \frac{5}{35}[/tex]
[tex]P(Work | Senior) = 0.14[/tex]
Answer:
14%
Step-by-step explanation:
add 25+5+5 (because that is all the numbers in the 'Seniors' row) and then take the 5 that is in the 'Work' column and put that over 25. (5/25 fraction as a percent is 14).

Answer:
I agree with Tyler. Here's why:
Step-by-step explanation:
A scaled copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes. They are both the same shape, but the other is half the size of Figure A. So I do agree with Tyler.
Hope this Helps, hope u have a great day :)
Answer:
I don´t agree with tyler
Step-by-step explanation:
I don´t agree with Tyler because if B was a scaled copy of A the bottom part would also increase. In figure A the bottom part is about 5 or 6 cm, and the sticks are 2cm, but in figure B the sticks are 4cm but the bottom part still measures the same. I hope it helped!

Answer: 3 miles.
Step-by-step explanation:
Since we are given the information that Ms. Wilson walked ¾miles each day. To calculate the total distance that Ms. Wilson will walk for 4 days, we have to multiply the distance walked each day by 4.
This will be:
= ¾miles × 4
= 3 miles
Therefore, Wilson walked a distance of 3 miles for the 4 days.

The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?
Area of the rectangle = Length * width
Factorize the area
A(x) = x^2+8x+15
A(x) = x^2+3x+5x+15
A(x) = x(x+3) + 5(x+3)
A(x) = (x+3)(x+5)
Since the width is x+3, the length of the rectangle will be (x+5) metres

A model rocket is launch from a platform 17 feet high in the initial velocity is 40 ft The path of the rocket is modeled by the equation 16x^2 +40X +17=0 When does the rocket land
Answer:
It will be in the air until P(x) is zero.
P(x) = -16x2 + 32x = -16x(x - 2)
P(x) = 0 ⇒ x = 0 or x = 2
It starts on the ground at x = 0, so the total time in the air must be x = 2 seconds.

Answer:
1 over 2
Step-by-step explanation:
9-(-7)=-2

-6-(-3)=-3
-2-4=-6
When you simplify both of the fractions -2 over -4 and -3 over -6
You get 1 over 2 as the slope for both. 1/2
The length of a rectangle is 2 yards longer than its width. If the perimeter of the rectangle is 64 yards, find its length and width.
Answer:
Length: 17 yards
Width: 15 yards
Step-by-step explanation:
If the length is 2 yards longer than the width, then the width is w, and the length is w+2
Equation for perimeter is [tex]P =2l+2w[/tex], where:
P = Perimeter
l = length
w = width
Plug in the values:
64 = 2(w+2) + 2w
Distribute:
64 = 2w + 4 + 2w
Combine like terms:
64 = 4w + 4
Subtract 4 from both sides:
60 = 4w
Divide 4 from both sides:
15 = w
So if w = 15, then
Width = w, which is 15 yards.
Length = w+2, which is 15+2 = 17 yards.

Lines L and M are parallel. 3/4 2/5 1/6 38 7 -L -M > Find : m 3 Enter the number that belongs in the green box. O [?]
The value of angle m∠3 = 142°.
When two lines meet at a point, an angle is created. An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character ∠. The circularity or rotation of an angle is often measured in degrees and radians.
According to the question, Lines L and M are parallel to each other.
The value of m∠8=38°
By the property of vertically opposite angles, m∠6=38°.
Now, by the property of alternate angles, m∠2= m∠6=38°.
Again, By the property of vertically opposite angles,m∠4=m∠2=38°.
As the sum of angles of a straight line = 180°
m∠3+m∠4 = 180°
m∠3+38°=180°
m∠3=180°-38°
m∠3=142°

Answer:
I'm not sure what you're looking for here, but here's some information I provided for you when solving for the perimeter or area of a rectangle.
Perimeter:
P = 2 (l + w)
P = 2 (84 + 30)
P = 2 x 114
P = 228 inches
Area:
A = lw
A = 84 x 30
A = 2,520 inches

Answer:
The speed of the jet in still air is 260 miles per hour.
Step-by-step explanation:
Given that a small jet can fly 858 miles in 3 hours with a tailwind but only 702 miles in 3 hours into a headwind, to find the speed of the jet in still air the following calculation must be performed:
858/3 = 286
702/3 = 234
(286 - 234) / 2 = X
52/2 = X
26 = X
286 - 26 = 234 + 26
260 = 260
Therefore, the speed of the jet in still air is 260 miles per hour.

B. 8 x 12
Step-by-step explanation:
First of all, it has an area of 96
So lets find the multiplication pair that equals 96.
10 x 10 = 100 NO
6 x 16 = 96 YES
8 x 12 = 96 YES
Now we have two equations: 8 x 12 and 6 x 16
Perimeter of 40 means:
2(a+b) = 40
Lets input the two equations:
2(8+12) = 2 x 20 = 40
2(6+16) = 2 x 22 = 44
So the dimensions that works is 8 x 12

You stand 40 feet from a tree. The anlge of elevation from the ground to
the top of the tree is 47 degrees. How tall is the tree? (round to the nearest
tenth)
9514 1404 393
Answer:
42.9 ft
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
where Opposite in this case is the height of the tree, and Adjacent is the distance to the tree.
tan(47°) = height/(40 ft)
height = (40 ft)·tan(47°) . . . . . multiply both sides by (40 ft)
height ≈ 42.9 ft
The tree is about 42.9 feet tall.
The equation V equals pi r squared h, where r represents radius and h represents height, is used to find the volume of a ________.
Answer:
Volume of a cylinder.
Step-by-step explanation:
The given equation is :
[tex]V=\pi r^2 h[/tex]
Where
r is the radius
h is the height
This equation is used to find the volume of a cylinder.
For example, a cylinder having radius of 7 units and height of 10 units, its volume will be :
[tex]V=\dfrac{22}{7}\times 7^2\times 10\\\\V=1540\ \text{unit}^2[/tex]
So, the given equation is used to find the volume of a cylinder.
