Step-by-step explanation:
the triangles are proportional.
if you look at AB and DE,
you'll notice that AB is half of DE.
so, triangle ABC's sides are half of triangle DEF
the measure DF is 10, so that means the measure AC is half of that, which is 5

Find three consecutive even integers such that the sum of the first and third increased by 18 is equal to three times the second.
Answers
Answer:
16, 18 and 20Step-by-step explanation:
x - an integer
2x - an even integer (the first)
Even integers increase by 1 so:
2x+2 - next consecutive integer (the second)
3(2x+2) - three times the second
2x+4 - the third consecutive integer
2x+2x+4 - the sum of the first and third
2x+2x+4+18 - the sum of the first and third increased by 18
2x+2x+4+18 = 3(2x+2)
4x + 22 = 6x + 6
-6 -6
4x + 16 = 6x
-4x -4x
16 = 2x
2x = 16
2x+2 = 18
2x+4 = 20
Check: 16+20+18=54; 3×18=54

In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.
Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth
Answers
Answer:
2 m/ s
a = F / m
a= 7.92 / 3.6
ie . 2.2 m/ s
Answer:
Step-by-step explanation:
1st step is by rearranging the formula
F=ma
M=f/a
A=f/m
2nd step is use the acceleration formula
A=f/m (acceleration=force divided by mass)
3rd step answer the question using the formula
A=?
F= 7.92N
M=3.6Kg --- 3600g (optional)
A=7.92/3600= 0.0022N/g or 7.92 / 3.6= 2.2N/Kg
4th step turning them to the nearest tenth
0.0022N/g= 0.0N/g or 2.2N/Kg= 2.2N/kg
DONE
TO SEE IF THE ANSWER IS CORRECT USE THE F=MA formula

slope of 1/2 that passes through the point (6,-4) in slope-intercept form
Answers
Answer:
y=1/2x-7
Step-by-step explanation:
slope intercept form: y=mx+b
mx= slope
b= y-intercept
y=1/2x+b
Now plug in 6 for x and -4 for y bc 6 is in the x-value and -4 is in the y-value.
-4=1/2(6)+b
-4=3+b
Subtract 3 from both sides
b=-7
y=1/2x-7
The equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.
To find the equation of a line with a slope of 1/2 that passes through the point (6, -4), we can use the point-slope form of a linear equation, which is:
y - y₁ = m(x - x₁)
Plugging in the values, we have:
y - (-4) = 1/2(x - 6)
y + 4 = 1/2(x - 6)
Now, let's convert the equation to slope-intercept form, which is in the form of y = mx + b, where m represents the slope and b represents the y-intercept.
Expanding and rearranging the equation:
y + 4 = 1/2x - 3
y = 1/2x - 7
Therefore, the equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.

36. A group of 30 students from the senior class
charters a bus to an amusement park. The total
amount they spend on the bus and admission
to the park for each student is $1,770.
A group of 50 students from the junior class
also go to the amusement park, but they
require two buses. If the group from the junior
class spent $3,190 in total, how much does it
cost to charter one bus?
LESSON 4-3 Solving Systems of
Answers
I got $720 because i did x + 30y = 1770, and then 2x + 50y = 3190, 5x + 150y = 8850, 6x + 150y = 9570 and lastly x = 720.
The required cost of one charter bus would be 720 dollars.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let's assume that cost to charter one bus would be x and the spend on the student would be y
According to the given situation, we can write the equations as
x + 30y = 1,770 ....(i)
2x + 50y = 3,190 or
x + 25y = 1,595 .....(ii)
Subtracting equation (ii) from equation (i), and solving for y
x + 30y - (x + 25y) = 1,770 - 1,595
5y = 175
y = 35
Substitute the value of y= 35 in the equation (i), and solve for x
x + 30(35) = 1,770
x + 1,050 = 1,770
x = 1,770 - 1,050
x = 720
Therefore, the cost of one charter bus would be 720 dollars.
