Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original incline
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees
The first lap of an auto race is 2,500 meters. This is 10% of the total race distance. What is the total race distance?
Answer:
25,000
Step-by-step explanation:
.10(x) = 2,500
X = 2,500/(.10)
X=25,000
The length of the total race track is 25000 meters.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Let, 'x' be the total distance.
Therefore, From the given information 10% x is 2500 meters, This can be numerically expressed as,
(10/100)×x = 2500.
0.1x = 2500.
x = 25000.

Answer:
(f ￮ g)(8) = - 6
Step-by-step explanation:
Evaluate g(8), then substitute the value obtained into f(n)
g(8) = 8 - 2 = 6 , then
f(6) = - 6
Answer:
-62
Step-by-step explanation:
Two functions are given to us , which are ,
[tex]\bf\implies f(n)= -n \\\\\bf\implies g(n)= n - 2 [/tex]
We need to find , ( f • g )(8) . So ,
⇒ ( f • g) = - n ( n - 2 )
⇒ ( f • g) = -n² + 2
⇒ (f • g) = 2 - n²
==================================
Substituting n = 8 :-
⇒ ( f • g)(n) = 2 - n²
⇒ ( f • g)(8) = 2 - 8²
⇒ (f • g)(8) = 2 - 64
⇒ ( f • g)(8) = -62 .
Hence the required answer is (-62) .16c^2+ 18c+5

1_____ × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also
2_____ times greater than 9.5 × 10-4.
Answer:
Well, 1 is 3.8 The second one is 40,
Step-by-step explanation:
I believe 1 is 3.8, b/c 1.9*2 is 3.8, and the difference between exponents makes 3 zeros, so 2000.
The second one is 40, I confirmed this by doing .0001 to replicate 10 to the negative 4th power
By doing 9.5*.0001*40, I got the 0.038 from 1
Answer:
3.8 × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also 4 times greater than 9.5 x 10-4.
Step-by-step explanation:
I started by doing 0.0000019 x 2000 and got 0.0038. If you move the decimal point 4 over you get 3.8.
EVERYONE ELSE IS WRONG!!! I got this correct on the test after retaking it, the second one is NOT 40 it is 4.

I hope I helped, if not please let me know and I will correct my answer.
Happy new year, good luck with your future studies.
Step-by-step explanation:
The probability of getting five quadrilateral with four congruent sides is,
⇒ 1 / 3
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
A six sided die is rolled then a quadrilateral is chosen at random parallelogram ,rhombus, rectangle, square and trapezoid.
Hence, Total number of outcomes = 6
And, We know that;
Square and Rhombus have four congruent sides.
Hence, Number of possible outcomes = 2
Thus, The probability of getting five quadrilateral with four congruent sides is,
⇒ 2 / 6
⇒ 1 / 3

Answer:
ASA
Step-by-step explanation:
If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of the other triangle, then the triangles are congruent.
The included side is the side between the vertices of the 2 triangles.
Here
∠ S = ∠ W ( 1 angle )
∠ R = ∠ X ( 2 angles )
RS = XW ( side between the 2 angles )
Thus the 2 triangles are congruent by the ASA postulate

9514 1404 393
Answer:
x = 3(y -1)
Step-by-step explanation:
In this, and any, "solve for ..." situation, you want to first take a look at where the variable of interest is in the equation, and what has been done to it.
Here, x is on the right side (only). It has these operations done to it:
multiplied by 1/31 added to the productYou solve for x by undoing these operations, in reverse order. As always, with any equation, you do the same thing to both sides of the equation.
__
First, we will undo "add 1". We do that by adding the opposite of 1.
y -1 = 1/3x +1 -1 . . . . . -1 added (to both sides)
y -1 = 1/3x . . . . . . . . . simplify
To undo the "multiply by 1/3", we can multiply by the "multiplicative inverse" (reciprocal) of 1/3. That is, we want to multiply by 3.
3(y -1) = 3(1/3x) . . . . . multiply (both sides) by 3
3(y -1) = x . . . . . . . . . simplify
We can leave it like this.
x = 3(y -1)
Or, we can eliminate parentheses using the distributive property .
x = 3y -3
These are completely equivalent equations with x as the subject.

3x + 1 = 10
Show work
Answer:
x = 3
Step-by-step explanation:
3x + 1 = 10
subtract 1 from both sides of the equation
3x + 1 - 1 = 10 - 1
3x = 10 - 1
3x = 9
divide both sides of the equation by 3
3x/3 = 9/3
x = 9/3
x = 3
Answer:
X=3
Step-by-step explanation:
3x+1=10 -> switch 1 3x = 10 - 1
3x = 9
9/3 = 3
