Answer:
2.5 cm
Step-by-step explanation:
let y represent the unknown distance
4 cm = 60 miles
y cm = 37.5 miles
we then cross multiply
4 × 37.5 = 60 x y
150 = 60 y
divide both side by 60
150/60 = 60y/60
y = 2.5cm
what percent of 120 is 57
The graph shows a trip taken by a car, where t is the time (in hours) and y is the distance
(in miles) from Phoenix.
a. Find the y-intercept of the graph. What does it represent?
b. Find the slope of the graph. What does it represent? c. How long did the trip last? d. How far from Phoenix was the car at the end of the trip?
e. Write an equation that represents the graph
Answer:
The answer is below
Step-by-step explanation:
The equation of a graph of a linear function is in the form:
y = mx + b;
where m is the slope of the graph, b is the y intercept, y and x are the variable.
Since y represent distance on y axis and t represent time on the x axis. We see that the graph passes the points:
(0, 100) and (6, 400). The equation of the graph is:
[tex]y-y_1=\frac{y_2-y_1}{t_2-t_1}(t-t_1) \\\\y-100=\frac{400-100}{6-0}(t-0)\\\\y-100= 50t\\\\y=50t+100[/tex]
a) The y intercept is 0. This means that initially the car is at 100 miles from Phoenix before the trip started. i.e. at 0 hours the distance is 100 miles.
b) The slope of the graph is 50. It means that the car traveled at a speed of 50 miles per hour
c) The end point of the graph is (6, 400), meaning the trip lasted 6 hours
d) The end point of the graph is (6, 400), meaning at the end of the trip, the car was 400 miles from Phoenix.
plz help find x !!!!!
Answer:
a. 38.5
Step-by-step explanation:
The triangles are similar. That means that the ratios are the same.

Answer:
[tex]\frac{20}{36}[/tex]
Step-by-step explanation:
the total amount of squares within this square is 36
and the number of shaded squares would be 20
so if 20 squares out of 36 squares are shaded, then the fraction is
[tex]\frac{20}{36}[/tex]
or 55.56%
(to find percentage multiply [tex]\frac{20}{36}[/tex] by 100)
Answer:
5/9
= 55.56% ( to the nearest hundredth).
Step-by-step explanation:
The total number of little squares in the large square = 6*6 = 36.
Total number of shaded squares = 2*6 + 2*4
= 12 + 8 = 20.
So the fraction of shaded part
= 20/36
= 5/9.
As a percentage this is 5*100/9
= 55 5/9%
= 55.55..... %

Answer:
The highest rate of birds is during the years 4 to 3
(remember that the lowest digit of number of negative is the highest and the highest is the lowest)
Step-by-step explanation:
Rate of Changes:
1 to 2: 5080.86 - 5238/ 2 - 1
= -157.14/1
= (convert to decimal) -157.1
2 to 3: 4928.43 - 5080.86/ 3 - 2
= -152.43/ 1
= -152.43
3 to 4: 4780.58 - 4928.43/ 4 - 3
= -147.85/ 1
= -147.85

A rectangle has an area of 2x2 - 19x +45 ft? What are the dimensions of the rectangle? (hint: factor)
The dimensions of the rectangle will be (2x - 9)(x - 5).
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.
The dimensions of the rectangle will be the factors of the quadratic equation.
2x² - 19x + 45
2x² - 10x -9x + 45= 0
2x( x - 5 )-9(x - 5)= 0
( 2x - 9 ) ( x - 5 ) = 0
Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).
