Answer:
first car : 115 liters
second car: 135 liters
Answer:
car 1 = 173.08 liters
car 2 = 76.92 liters
Step-by-step explanation:
the first step is to find what ratio of car 1 is to car 2
that is 18:8
total ratio is 26
the combination of car 1 and 2 = 26
the total km = 3350
total fuel = 250 liters
car 1 = 18 x 250 liters
26
= 173.08 liters
car 2 = 8 x 250 liters
26
= 76.92 liters
173.08 + 76.92 = 250

Answer: 1 gallon
Step-by-step explanation:
Hi there!
Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.
[(12*18)-(7*3)]/200
(215-21)/200
196/200
0.98
use SSS, SAS, ASA, AAS or HL star if the two triangles are congruent, if they are state how you know?
Answer:HL, ASA, SSS, ASA
Step-by-step explanation:
1. HL because the hypotenuse are equal by the reflexive property and the at least one pair of legs are congruent. Also the interior angles are congruent.
2. ASA because the interior angles are both congruent and the included side is congruent by the reflexive property.
3. SSS because the corresponding sides are congruent and the line is congruent by reflexive property so all the sides are congruent.
4. ASA because the interior angles are congruent and the other pair of angles are also congruent because they are verticle angles. The including sides are also congruent so therefore angle-side-angle.

Perform these transformations on △DEF.
Reflect △DEF across the x-axis and label the resulting image△D'E'F'.
Rotate △D'E'F' 90° clockwise about the origin and label the resulting image △D''E''F''.
Translate △D''E''F'' according to (x,y)→(x-2,y+2) and label the image △D'''E'''F'''.
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point A(x, y) is reflected across the x axis, the new location is at A'(x, -y).
If a point A(x, y) is rotated 90° clockwise about the origin, the new location is at A'(y, -x).
If a point A(x, y) is translated a units left and b units up, the new location is at A'(x-a, y+b).
From the image attached, the location of triangle DEF is D(2, 6), E(2,3) and F(5, 3).
If △DEF is reflected across the x-axis, the resulting image △D'E'F' is at D'(2, -6), E'(2, -3) and F'(5, -3).
If △D'E'F' is rotated 90° clockwise about the origin, the resulting image △D''E''F'' is at D''(-6, -2), E''(-3, -2) and F''(-3, -5).
If △D''E''F'' is translated by (x,y)→(x-2,y+2), the resulting image △D'''E'''F''' is at D'''(-8, 0), E'''(-5, 0) and F'''(-5, -3).

The longer leg of a right triangle has a length of 15. One angle in the triangle is 60 degrees. What is the length of the shortest leg?
The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Given that the longer leg of a right triangle has a length of 15, hence hypotenuse = 15. One angle in the triangle is 60°. Let x represent the shortest side.
The shortest side is adjacent to the 60° angle, hence:
cos(60) = x / 15
x = 7.5
The shortest side of a right triangle with a hypotenuse of 15 and one angle of 60° is 7.5

Describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
f(x) = 9 cos x ; g(x) = cos x (3 points)
Answer:
The transformations required to obtain the graph of the function f(x) from the graph of the function g(x) is vertical stretch
Step-by-step explanation:
We need to describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x).
We have g(x) = cos x
After transformation we get
f(x)= 9 cos x
According to transformation rule:
if f(x) is transformed into a.f(x) then the transformation is vertical stretch or compression.
if a > 1 then transformation is vertical stretchif 0 < a < 1 then transformation is vertical compressionIn our case
g(x)= cos x
f(x) = 9 cos x
a=9 and a>1 so, the transformation is vertical stretch.
So, The transformations required to obtain the graph of the function f(x) from the graph of the function g(x) is vertical stretch

what is 457.894 to 2 deimal places
Answer:
228.947
Step-by-step explanation:
Answer:
457.894
Step-by-step explanation:
"What is 457.894 rounded to 2 decimal places?" is the same as asking, "What is 457.894 rounded to two decimal points?" or "How to round 457.894 to two decimal places."
The main point is that you want to round 457.894 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 457.894. To eliminate the last digit in 457.894, we use the following Two Decimal Places Rules to get the answer:
Two Decimal Places Rule #1: If the last digit in 457.894 is less than 5, then remove the last digit.
Two Decimal Places Rule #2: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is less than 9, then remove the last digit and add 1 to the second to the last digit.
Two Decimal Places Rule #3: If the last digit in 457.894 is 5 or more and the second to the last digit in 457.894 is 9, and the third to the last digit is less than 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the third to the last digit.
Two Decimal Places Rule #4: If the last digit in 457.894 is 5 or more and the second to the last digit is 9, and the third to the last digit is 9, then add 1 to the number on the left side of the decimal point and make the right side of the decimal point 00.
When rounding 457.894 to two decimal places we use Two Decimal Places Rule #1. Therefore, the answer to "What is 457.894 rounded to 2 decimal places?" is:

Solve the following simultaneous equations
y=x^2
y= x+6
The required solution of the given simultaneous equations are x = 2, 3 and y = 3,9.
What are simultaneous equation?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Now the given simultaneous equations are,
y = x^2 ...(i)
y = x + 6 .....(ii)
Equating (i) and (ii) we get,
x^2 = x + 6
or, x^2 - x - 6 = 0
Solving we get,
x^2 - 3x - 2x - 6 = 0
⇒ x(x - 3) -2(x - 3) = 0
⇒ (x - 2)(x - 3) = 0
So, x = 2, 3
Putting x = 2, 3 in equation (i) we get,
y = 2^2
⇒ y = 4
and,
y = 3^2
⇒ y = 9
Thus, y = 3,9
Thus the required solution of the given simultaneous equations are x = 2, 3 and y = 3,9.

Step-by-step explanation:
3 BC = EF
3 AC = DF
M= i + r ; solve for r
Answer:
m - i = r
Step-by-step explanation:
In this question, you are solving for "r".
Solve:
M= i + r
We have to get "r" by itself, so subtract "i" from both sides.
m - i = r
Since we found what "r" is, we can't solve any further.
m - i = r would be your answer.
