Answer:
The shadow is 15 feet long.
Step-by-step explanation:
This is a proportion question. Build a proportion using two fractions.
[tex]\frac{\text{tree height}}{\text{shadow length}}[/tex]
[tex]\frac{15}{9}=\frac{25}{x}[/tex]
"Cross-multiply" -- you might know this as the Means-Extremes Property of Proportions.
[tex]15x=(25)(9)\\15x=225\\x=15[/tex]
Two trains started from the same station at the same time and traveled in opposite
directions. After traveling 4 hours, they were 480 miles apart. The rate of the fastest
train exceeded the rate of the slow train by 10 mph. Find the rate of each train.
Please help!!
Answer:
Fastest train: 65 mph
slowest: 55 mph
Step-by-step explanation:
Divide 480 by 4
=120
To find average speed divide 120 by 2
=60
call the speed of the slowest train y.
y+(y+10)=120
2y=110
y=110/2=55
y+10=65

Find the missing term: (x+3)² = x² + 6x + _____
Answer:
9
Step-by-step explanation:
The formula for (a + b)^2 expands out to: a^2 + 2ab + b^2. In the case of this problem, a equals x and b equals 3. We can substitute to get:
(a + b)^2 = a^2 + 2ab + b^2
(x + 3)^2 = x^2 + 2(x)(3) + (3)^2
(x + 3)^2 = x^2 + 6x + 9
So, the missing term is 9.
Another way to do this is to multiply (x + 3)(x + 3) since it's the same thing:
(x + 3)(x + 3)
x^2 + 3x + 3x +9
x^2 + 6x + 9
By solving this way, you get the same answer.
Answer:
It would be 9.
Step-by-step explanation:
To do this, lets expand the equation (x+3)^2 by turning it into:
(x+3)(x+3)
Now, lets try something called the FOIL method. This is where all of the terms of the equation are multiplied in the order:
1) First
2) Outer
3) Inner
4) Last
So in (x+3)(x+3), each of the first parts of each parentheses box are x's, and x times itself equals x^2 so:
x^2 + ? + ? so far.
Next, with the Outer & Inner parts, they would be x * 3 and 3 * x. With this, you would get 3x and 3x. These can be added to get 6x, the middle part of the equation.
x^2 + 6x + ? so far.
Lastly, for the answer. Time to do the last part of each parentheses box, you would get 3 * 3, which gives you 9.
x^2 + 6x + 9.

What is the area in square feet of the shaded part of the rectangle below
Which correctly describes a cross section of the square pyramid? Select three options. A square pyramid with 2 foot sides. A cross section parallel to the base is a square with side lengths of 2 ft. A cross section parallel to the base is a square with side lengths of less than 2 ft. A cross section perpendicular to the base through the top vertex is a triangle with the same dimensions as the triangular sides of the pyramid. A cross section perpendicular to the base through the top vertex is a triangle with different dimensions than the triangular sides of the pyramid. A cross section that is perpendicular to the base that does not pass through the top vertex of the pyramid is a trapezoid.

Please someone help me the question is in the picture above
Answer:
Step-by-step explanation:
First, convert the equation into slope-intercept form: y > -3x + 5
Second, place a point on (0,5). You can do this by starting at the origin and counting up by 5. This is your y-intercept.
Third, start from your y-intercept and move down 3 and right 1. Draw a point. Keep doing this until you hit the end of the graph.
Fourth, start from your y-intercept and move up 3 and left 1. Draw a point. Keep doing this until you hit the end of the graph.
Then, connect your dots by making a dashed line.
Finally, Shade above the line.

Given y varies inversely as x, and y = 5 when x = 9. *Write the inverse function
Answer:
y = k/x
k = 45
y = 45/x
Step-by-step explanation:
y varies inversely as x
y = k/x
y = 5 when x = 9
y = k/x
5 = k / 9
Cross product
5 * 9 = k
k = 45
Constant of proportionality, k = 45
y = 45/x
9 + 9 + 9 + 9 = _ x 9

Answer:
Slope: 5, Y-intercept: 150
Step-by-step explanation:
=> Slope = Change in y / Change in x
Change in y = +35
Change in x = +7, therefore;
Slope = 35 / 7
Slope = 5
=> Y-intercept is the y-value where x = 0, therefore;
Y-intercept = 150
Hope this helps!

i can sill confirm it is Slope: 5, Y-intercept: 150

Amy has a piece of wood that measures 42 inches. The model shows the length remaining after she cut a piece from the 42-inch piece of wood. About how many inches did Amy cut from the 42-inch piece of wood?
Answer:
She has 42 pieces of wood each of 1 inch of length.
Step-by-step explanation:
Amy has 42 inches piece of wood.
She has to cut an inch.
After cutting pieces of inch each she counts the pieces to be 42.
Mathematically
Total length / unit lenght = Number of pieces
42 inches/ 1 inch= 42 pieces.
She has 42 pieces of wood each of 1 inch of length.

Answer:
What is the angle of elevation θ that is required for a hit ball to just clear the center field fence when it is hit 2 ft above the ground? Show all of your work and round your answer to the nearest hundredth of a degree.
Distance from Home plate to the center field fence: 425 ft
Height of the center field fence: 8 ft
____________________________
ANSWER:
The fence height = 8ft
The fence height takes 2 ft from the ground and doesn't count towards the angle.
Therefore subtract the difference = 8-2 = 6ft
The fence height from the 2ft to the fence top = 6ft
Angle of elevation (θ):
Tan(θ) = opposite/adjacent
Adjacent = Distance from Home plate to the center field fence = 425 ft
Opposite = 6ft
Tan(θ) = 6/425Tan(θ) = 0.0141θ = arctan(0.0141)arctan = inverse of tangent = tan-¹θ = 0.8078°Angle of elevation (θ) = 0.81°
