Step-by-step explanation:
A ice skater jumped an turned 1 full circle in the air how many one degree angles did she turn through
EMERGENCY HELP PLS: The state decided that the angle a wheelchair ramp
makes with the ground should be no more than 4.3º.
a) What is the maximum height of a 25-foot ramp? Round to the nearest tenth of a foot.
b) What distance along the ground would this ramp
cover? Round to the nearest tenth of a foot.
Maximum height = ? ft.
Distance along the ground ? ft.
Answer:
1.9 feets (nearest tenth) ;
24.9 feets
Step-by-step explanation:
Given that :
Angle, θ = 4.3°
Length of ramp = 25
Maximum Height, h ;
sinθ = opposite / hypotenus
Sin 4.3 = h / 25
0.0749787 * 25 = h
1.874 feet = h
1.9 feets (nearest tenth)
Distance along the ground the ramp could cover :
Cos θ = Adjacent / hypotenus
Cos 4.3 = x / 25
0.9971851 = x / 25
0.9971851 * 25 = x
x = 24.929
x = 24.9 (nearest tenth)
HURRYYYY PLEASEEEE
find the value of x.
Answer:
x=31
Step-by-step explanation:
Hello there!
the shown angles are supplementary meaning that the sum of the two is 180
so we create an equation
180=3x+25+2x
step 1 combine like terms
3x+2x
now we have
180=25+5x
step 2 subtract 25 from each side
180-25=155
now we have
155=5x
step 3 divide each side by 5
155/5=31
5x/5=x
we're left with x=31

How much interest will you earn by leaving $500 in a savings account for 3 years with an interest rate of 1.5%?
*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
: 522.5$
:
First calculate yearly interest
500 x 0.015 = 7.5
7.5 x 3(for 3 years) = 22.5
Then add them together!
500 + 22.5 = 522.5

Step-by-step explanation:
Given the function F (x) = x2 -2x -5 determine the average rate of change of the function over the interval -5 < x <6.
Answer:
1
Step-by-step explanation:
Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.
The average value of a function f(x) over an interval [a, b] is
f(b) - f(a)
ave. val. = ---------------
b - a
which in this particular case is
19 - 30
ave. val. = ----------------- = -11/11 = 1
6 - (-5)
The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.
solve the system of linear equations by substitution
Answer:
(-4, 5)
Step-by-step explanation (work shown in attached picture):
1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.
2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.
Since x = -4 and y = 5, the solution is (-4, 5).
Answer:
Value of x is -4 Value of y is 5Step-by-step explanation:

Giorgio is learning to play the piano. By the end of each month, he has learned 3 new songs.
Part A Graph 5 points on the coordinate plane below that show the total number of songs Giorgio has learned by the end of each month from month 1 to month 5.
Which equation represents the relationship between the independent variable, x , and the dependent variable, y?
Answer: y = 3x
Step-by-step explanation:
The answer is y=3x because every month Giorgio learns a new song. so for the first month they learned 3 songs and in the second month they learn 3 more that adds up to 6 song total, so if you just times the month by 3 you will get your answer.
Answer
the way you have it there is right for the giorgio and for the second one it will be x=3x
he output is five less than triple the input

Write an equation in point-slope form of the line that passes through the point (5, 1) and has a slope of -3
Answer:
y - 1 = -3(x - 5)Step-by-step explanation:
An equation in point-slope form of the line that passes through the point (x₁,y₁) and has a slope of m:
y - y₁ = m(x - x₁)
m = -3
(5, 1) ⇒ x₁ = 5, y₁ = 1
Therefore:
y - 1 = -3(x - 5)

HELP ASAPPPPP NO WRONG ANSWER PLS
Answer:
40
Step-by-step explanation:
one cubic cm would be 2x2x2=8 half cm³
you have 1x2x2.5 cm cube = 5 cm³
5 x 8 = 40
another way to look at it:
2 1/2 = 5 half-cubes long
2 = 4 half cubes wide
1 = 2 half cubes tall
5 x 4 x 2 = 40
The measures of the three angles of a triangle are given by x+4,x, and 2x. What is the value of x
Answer:
x = 44°
Step-by-step explanation:
The sum of all the interior angles of a triangle = 180°
so:
(x+4) + x + 2x = 180°
reducing:
4x + 4° = 180°
4x = 176°
x = 44°
