Jack’s car used 18 gallons of gasoline to go 468 miles. At that rate, how many gallons would be used to go 754 miles? Explain how you know.
Answer:
29 gallons.
Step-by-step explanation:
For every gallon, a total number of 468/18 miles = 26 miles could be travelled.
And hence, to travel 754 miles, a total of 754/26 gallons = 29 gallons would be needed.

108 is 36% of what number? Write and solve a proportion to solve the problem.
Answer: 300
Step-by-step explanation:
Let the number be represented by x.
Therefore, based on the information given in the question, this can be expressed as:
36% of x = 108
36/100 × x = 108
0.36 × x = 108
0.36x = 108
x = 108/0.36
x = 300
Therefore, the number is 300

The measure of an angle is 26°. What is the measure of its complementary angle?
Answer:
64
Step-by-step explanation:
Complementary angles have to add up to 90.
90-26=64.
Answer:
64°
Step-by-step explanation:
Complementary angle means it add up to 90°
26° + x = 90°
x = 64°
Solve for x and all the missing angles.
(-11+3y)
(34+Y)
(37+y)°
Answer:
y=24; Angle 1: 61 degrees; Angle 2: 58 degrees; Angle 3: 61 degrees
Step-by-step explanation:
-11+3y+34+y+37+y=180 The sum of all the angles in a triangle is 180 degrees.
60+5y=180 Combine like terms
5y=120 Subtract 60 from 180
y=24 Divide 120/5
Angle 1: -11+ 3(24)= 61 degrees
Angle 2: 34+24=58 degrees
Angle 3: 37 + 24= 61 degrees
One litre of paint covers 1.5 square meters. How many litres must I buy so that I have enough to paint a wall 6 m long and 3 m high ?
Answer:
12 litres
Step-by-step explanation:
The area to be covered is
A = 6 × 3 = 18 m²
Divide the area by 1.5 for required amount of paint, that is
18 ÷ 1.5 = 12 litres
I(t) = 27, 992 * (1.017) ^ t covert to log
Answer:
By 2034 Texas per capita income would reach at least $50,000
Step-by-step explanation:
Given;
[tex]I(t) = 27,992(1.017)^t[/tex]
Converting the given function to log;
[tex]I(t) = 27,992(1.017)^t \\\\\frac{I(t)}{27,992} = (1.017)^t\\\\Log_{1.017} ( \frac{I(t)}{27,992} )= t \\\\(Based \ on \ log \ rule; if \ a = b^y , in \ log \ it \ will \ be \ written \ as, Log_b \ a = y)[/tex]
(B) When I(t) = $50,000, the time "t" will become;
[tex]Log_{1.017} ( \frac{I(t)}{27,992} )= t\\\\Log_{1.017} ( \frac{50,000}{27,992} ) = t\\\\Log_{1.017} (1.7862) = t\\\\34.4 \ years = t[/tex]
Thus, by 2034 Texas per capita income would reach at least $50,000

Answer:
2^-15
Step-by-step explanation:
y = -2x + 13 when x = 6
Answer: 1
Work: After plugging in the 6 in the X, the new equation is -2(6) + 13. After doing the multiplication of -2 and 6, you get -12. Add -12 + 13, and the answer (Or y) equals 1.

A. Part C. Ponto
B Parts D. Point
Answer:
1. B. point B.
2. C. point C.
3. C. point C.
Step-by-step explanation:
1. In order to find the graph's y-intercept, we need to locate the point where the line crosses the y-axis. This will always happen at x=0, therefore, the y-intercept is located at point B (0,-4)
2. In order to find the x-intercept, we need to find the point where the line crosses the x-axis. This will generally happen when y=0, so that will be point C (2,0)
3. In order to find the graph's zero, we need to find the point where y=0. In other words, the graph's zero is the point where the function is equal to zero (the x-intercept) so this will br point C again (2,0)
If RSTU is translated by the rule (x,y) > (x+2, y-10) , in which quadrant will the image R'S'T'U be located ?
Answer:
D) Quadrant 3
Step-by-step explanation:
ok so lets get a random point and try it out i see -10 is a big number so i will use R and see where it is and then t
R(-8,3) so add 2 to x and minus 10 y
R'(-6,-7)
Now t
T(-4,9)
(+2,-10)
T'(2,-1)
It is Quadrant 3
If RSTU is translated by the rule (x, y) ⇒ (x + 2, y - 10) the image R'S'T'U be located at the D. Third quadrant.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
From the given diagram, the coordinate of the vertex(T) is (- 4, 10).
Let, T' be the vertex when the quadrilateral is translated by the rule
(x, y) ⇒ (x + 2, y - 10).
Therefore, The translated coordinate of the vertex(T') is,
(- 4 + 2, 10 - 10).
= (- 2, 0).
So, The quadrilateral will lie in the third quadrant.

Answer:
Answer: x=4, y=10
Step-by-step explanation:
Lines and Angles
When lines cross, the angles formed in the intersections meet certain properties that help us to solve some geometry problems.
We must recall the so-called linear angles, defined as the adjacent angles formed in the point where two lines cross.
Linear angles always add up to 180°
We can see line m intersects with the horizontal (unnamed) line forming two pair of linear angles, thus:
29x - 3 + 15x + 7 = 180
Simplifying:
44x +4 = 180
Subtracting 4:
44x = 176
Dividing by 44:
x = 176/44
x = 4
Now below the horizontal line, we find other pair of linear angles, thus:
13y - 17 + 15x + 7 = 180
Substituting x=4:
13y - 17 + 60 + 7 = 180
Simplifying:
13y + 50 = 180
Subtracting 50:
13y = 180 - 50 = 130
Dividing by 13:
y = 130/13 = 10
y = 10
Answer: x=4, y=10
