Answer:
260 miles
Step-by-step explanation:
Given that:
Distance covered in 7 hours = 455 miles
Number of miles train will travel in 4 hours
Average travel speed per hour :
Distance traveled / time taken
455 miles / 7 hours
= 65 miles per hour
Number of miles traveled in 4 hours :
Average Speed per hour * time
(65 * 4) = 260 miles

A butcher has 3 1 3 pounds of ground beef that will be priced at $1.35 per pound. He divides the meat into 8 equal packages. To the nearest cent, the price of each package is $ .
Answer:
$0.56
Step-by-step explanation:
Cost of 3 1/3 pounds of beef at $1.35 per pound
= 3 1/3 × 1.35
= 10/3 × 1.35
= $4.5
He divides the meat into 8 equal packages. To the nearest cent, the price of each package is $
= $4.5 / 8
= $0.5625
Approximately $0.56 to the nearest cent

Given ABCD what is the value of y?
Answer:
x=7
y=5
Step-by-step explanation:
quadrilaterals have 360 degrees, and their opposite angles are equal
15x+5=16x-2
7=x
(plug back in to find angle)
15(7)+5=110
that angle, plus opposite angle, equals 110.
360-220=140
140/2=70
now we know the value of other unsolved angle
70=12y+10
60=12y
5=y

What is the image point of (−2,5) after a translation left 5 units and up 3 units?
Answer:
(-7,8)
Step-by-step explanation:
The given point (x,y)=(-2,5)
Assuming that right and up directions are positive, so left and down directions are negative.
So, after a translation left 5 units and up 3 units, the image point = (x-5, y+3)
=(-2-5, 5+3)= (-7,8)
Hence, the image point is (-7,8).

2) 20% decrease
Work:
1)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]8.8 - 6.5 = 2.3[/tex]
-divide 2.3 by the orriginal ammount (8.8) to find your answer as a decimal
[tex]2.3 \div 8.8 = 0.261[/tex]
-take 0.261 and multiply it by 100 to have your answer as a percent
[tex]0.2614 \times 100 = 26.1[/tex]
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease
2)
-subtract the larger # from the smaller # to figure out what the change was.
[tex]15 - 12 = 3[/tex]
-divide 2.3 by the orriginal ammount (15) to find your answer as a decimal

May I plz get some help plz
Step-by-step explanation:
5x +10° + 58° = 11x + 2°( Exterior angle of a triangle is equal to the sum of two opposite interior angles)
5x + 68° = 11x + 2°
11x - 5x = 68° - 2°
6x = 66°
x = 66° / 6
Therefore x = 11°
Hope it will help you :)
is this correct? plz answer only if you know for sure.
Answer:
2x+3x=150 ( sum of opposite interior angle of triangle is equal to the exterior angle)
5x=150
x=150/5
x=30

If f(x) = 2x, which of the following shows the graph of f(x) = 2(x) + 2?
Answer: the first graph
Step-by-step explanation:
The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The correct option is A.
What is the y-intercept of a function?The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At the y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
Given f(x)=2, therefore, the graph will have a y-intercept as 0.
But when the value of f(x) = 2(x) + 2, then the graph of the function will have the y-intercept at 2.
Hence, the correct option is A.
