Answer:
500-10x=250
x=how much the bird descended in a second
the bird will land on the ground in another 10 seconds.
Step-by-step explanation:
the bird will land on the ground in 10 seconds since it descended 250 ft in 10 seconds so that is 25 ft per second. then do 250/25 and you get 10. that is how you know the bird will land on the ground in 10 seconds.
Answer:
a) [tex]h(t)=500-25t[/tex]
b) [tex]t=20[/tex]
Step-by-step explanation:
a)
Let [tex]h[/tex] = height above ground
Let [tex]t[/tex] = time
Because the bird descended down to 250 feet in 10 seconds with a steady rate, that means it descends 25 feet per second.
∴ [tex]h(t) = 500-25t[/tex]
b)
To find the time it takes until the bird reaches the ground, [tex]h[/tex] must equal [tex]0[/tex]:
[tex]0=500-25t[/tex]
[tex]25t=500[/tex]
[tex]t=20[/tex]
∴ It takes 20 seconds for the bird to reach the ground.

which expression is equivalent to square root 48x^5 if x > 0
Answer: C:4x^2 square root of 3x
Step-by-step explanation:
Just got it right on Plato
C. 4[tex]x^{2} \sqrt{3x}[/tex] is equivalent to the expression [tex]\sqrt{48x^{5} }[/tex] if x>0
What do you mean by equivalent algebraic expression?An algebraic expression may be a blend of constants, coefficients, factors, and scientific operations. An algebraic expression can comprise of a number of terms or a few. Equivalent algebraic expressions are expressions that appear different but work the same way. If two algebraic expressions are equal, then on assigning the same value to the variables the two expressions will give the same value.At least two expressions are required to check for equality and You can substitute in nearly any value for the variable when trying to determine if two expressions are equivalent.
Expression:
[tex]\sqrt{48x^{5} }[/tex] if x>0
= [tex]48^{1/2}(x^{5})^{1/2}[/tex]
= [tex]48^{1/2}x^{5/2}[/tex]
= (2×2×2×2×3[tex])^{1/2}x^{5/2}[/tex]
= 2×2×[tex]3^{1/2}[/tex]×[tex]x^{5/2}[/tex]
= 4[tex]\sqrt{3} x^{5/2}[/tex]
= [tex]4\sqrt{3}x^{2} x^{1/2}[/tex]
= [tex]4x^{2} \sqrt{3x}[/tex]
Therefore, [tex]\sqrt{48x^5}[/tex] = [tex]4x^{2} \sqrt{3x}[/tex] if x>0
Hence, 4[tex]x^{2} \sqrt{3x}[/tex] is equivalent to the expression [tex]\sqrt{48x^{5} }[/tex] if x>0

In triangle ABC, the measure of angle A is 95º and the
measure of angle B is 35º. What is the measure of angle C?
A
50°
B
60°
с
140°
D
180°
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ A + ∠ B + ∠ C = 180°, so
95° + 35° + ∠ C = 180
130° + ∠ C = 180 ( subtract 130° from both sides )
∠ C = 50° → A

On Tuesday morning, the temperature is -5º F. The temperature rises 3 4 degree each hour for 6 hours before dropping 1 4 degree each hour for 3 hours. What is the temperature, in degrees Fahrenheit, after 9 hours?
Answer:
The temperature in degrees after 9 hours is -1.25 degrees Fahrenheit
Step-by-step explanation:
Here, we want to know the temperature after 9 hours
Per hour rise each hour is 3/4 degree = 0.75 degree
In 6 hours that will be 0.75 * 6 = 4.5 degrees
Or hour drop is 1/4 = 0.25 degree
In 3 hours, that will be 0.25 * 3 = 0.75 degree
Since it is a drop, we have -0.75 degree
Temperature after 9 hours will be;
-5 + 4.5 -0.75
= -5.75 + 4.5 = -1.25 degrees fahrenheit

3 hats and 2 scarves costs £12.
5 hats and 4 scarves costs £21.
Find the cost of a hat.
Find the cost of a scarf
Answer:
hat=£(9*9)/3*24)/3/8/9
Scarf=£1.5
Step-by-step explanation:
Let's suppose hats is the variable h
And Let's suppose scarves is the variable s
3h+2s=12
5h+4s=21
so, 3h+2s=12 which is also 2s=12-3h
so, in the equare 5h+4s=21 we can replace the 4s with 2(12-3h) Now the equation is this:
5h+24-6h=21
*Simplified*
Now 5h-6h= -1h
-1h+24=21
+1h +1h
on each side.
now the equation is(remember 1h=h): 24=h+21
I think you can do it now.
Now with the cost of the hats, we can use the first equation: 3h+2s=12
h=3
3*3=9

In the 48 years between 1842, the average rate of erosion at horseshoe falls was 33 divided by 50 metre per year. In the 22 years between 1905 and 1927 the rate of erosion was 7 divided by 10 meter per year . Approximately how much total erosion occurred during these two time periods
Answer:
47. 08 meters
Step-by-step explanation:
Given that:
In 48 years between 1842 :
Rate of erosion = 33/50 meters per year
Between 1905 - 1927 (22 years)
Rate of erosion = 7/10 meters per year
Approximately how much total erosion occurred during these two time periods ;
Total erosion that occured within 1842:
Rate of erosion * number of years
(33/50)m * 48
0.66 meters * 48
= 31.68 meters
Total erosion that occured between 1905 - 1927:
Rate of erosion * number of years
(7/10)m * 22
0.7 meters * 22
= 15.40 meters
total erosion which occurred during these two time periods ;
31.68 meters + 15.40 meters
= 47.08 meters
Answer:
47. 08 meters

A hiker cycles 9 miles in 2/3 of an hour. Make a chart and fill it in to show how far he will bike if he maintains the same pace for 2 hours, 3hours, 3.5 hours.
Answer:
2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles
Step-by-step explanation:
1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)
2.) 2 hours: 13.5 * 2 = 27 miles
3.) 3 hours: 13.5 * 3 = 40.5 miles
4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles
9 miles in 2/3 of a hour.
in 1 hour = 9 X 3/2 = 18.2 miles
In 2 hrs = 27 miles
in 3 hrs = 54.6 miles
in 3.5 hrs = 63.7 miles
