Find three consecutive even integers such that the sum of the smallest and the largest is 36.
Answer:
Step-by-step explanation:
The consecutive even integers are (2n-2), (2n), and (2n+2), where n is an integer.
(2n-2) + (2n+2) = 36
4n = 36
n = 9
(2n-2) = 16
(2n) = 18
(2n+2) = 20

Write the equation of a line that passes through the point (0, 3) and (-4, 11). *
Answer:
y = -2x + 3.
Step-by-step explanation:
The slope = (11-3)/(-4-0)
= 8/-4
= -2.
Using the point-slope form of a straight line:
y - y1 = m(x - x1)
Here m = -2 and (x1, y1) = (0,3). then
y - 3 = -2(x - 0)
y - 3 = -2x
y = -2x + 3.

Work out the coordinates of the midpoint of AB
Answer:
a) It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are: A(-2, -1)
b) We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.
Please check the attached graph.
c) The coordinates of the midpoint of AB: [tex]\left(-2,\:\frac{3}{2}\right)[/tex]
Step-by-step explanation:
Part a)
Important Tip:
The coordinates of point A can be determined by checking the location of point A.It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are:
A(-2, -1)Part b)
We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.
Please check the attached graph.
Part c)
We can determine the coordinates of the midpoint of AB using the formula
[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
In our case, we have:
A(x₁, y₁) = A(-2, -1)
B(x₂, y₂) = B (-2, 4)
so substituting [tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex] in the formula
[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]=\left(\frac{-2-2}{2},\:\frac{4-2}{2}\right)[/tex]
Refine
[tex]=\left(-2,\:\frac{3}{2}\right)[/tex]
Therefore, the coordinates of the midpoint of AB: [tex]\left(-2,\:\frac{3}{2}\right)[/tex]

<HAM=180-<HAJ=180-42=138IS YOURANSWER
Answer:
138°
Step-by-step explanation:
∠JAM = 180°
∠JAH = 42°
∠JAH + ∠HAM = 180° because they are supplementary
42° + ∠HAM = 180°
∠HAM = 180°-42°
∠HAM = 138°

Nell's mortgage is $50,150 at 10 percent for 30 years.
What is her monthly payment if she must pay $8.78 per $1,000?
Answer:
The correct option is a.
Step-by-step explanation:
It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.
EMI on $1000 is $8.78, so EMI on $1 is
EMI on $1 = 8.78/1000 = 0.00878
EMI on $50150 is
EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32
Therefore the correct option is a.

Step-by-step explanation:
Please help me with these questions guys
Answer:
6m
Step-by-step explanation:
You need to use trigonomtery: SOHCAHTOA
Since we are looking for the height, we should use the Sine rule:
Sine(37) = opposite/hypotenuse
We already have our hypotenuse which is 10
sine(37) = opposite/10m
Now we re-arrange to find the opposite(which is our height)
opposite = 10m x sine(37)
opposite = 6.018
Therefore height = 6 to the nearest metre

After an office party, 4 1/3 pizzas are left. A day later, there are 1 5/6 pizzas left. How munch pizza was eaten during the day after the party
Answer:
15/6 pieces of pizza were eaten. Which is equivalent to 2.5. So 2.5 pizzas were eaten.
Step-by-step explanation:
Just did the math. Convert 4 1/3 to 0/6. So 1 times 2 is 2, and 3 times 2 is 6. Which would give you 4 2/6 which has the same denominator as 1 5/6.
A boat traveled 240 miles downstream and back. The trip downstream took 12 hours. The trip back took 24 hours. What is the speed of the boat in still water? What is the speed of the current?
Answer:
rate boat = 15 mph
rate current = 5 mph
explanation:
d = r * t
t = d/r
240 / (r_boat + current) = 12 Multiply both sides by r_boat + r_current.
240 = 12(r_boat + current)
240/ (r_boat - current) = 24 Multiply both sides by r_boat - r_current
240 = 24*(r_boat - current)
Since the distances are the same in both equations, you can equate the right side of each.
12 (r_boat + current) = 24(r_boat - current) Divide by 12
r_boat + current = 2 (r_boat - current) Remove the brackets.
r_boat + current = 2*r_boat - 2* current add 2 currents to both sides
r_boat + 3currents = 2*r_boat Subtract r_boat both sides
3 currents = r_boat.
240 = 12*(r_boat + current. Divide by 12
20 = r_boat + current Put 3 currents in for r_boat
20 = 3currents + 1 current Combine
20 = 4 currents Divide by 4
5 = current
The rate of the current = 5 miles / hour
3 currents = r_boat
3*5 = rate_boat
15 = rate of the boat

Step-by-step explanation:
There is a flu outbreak at your school that starts with 10 people. The number of ill students increases by 20% each hour. Write an exponential function to represent the total number of ill students, f(x), where x is the number of hours after the outbreak. How long does it take for at least 100 people to be ill with the flu?
please explain how you do the problem
thank you
Answer:
y = (10 * 0.2) ^ x
Y = (2)^x
Y = 2^x + 10
6.5 hours
Step-by-step explanation:
Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.

Find the solution to the following system of equations using substitution or elimination y=-2x+7 y=3x-8
Answer:
x = 3, y = 1
Step-by-step explanation:
By substitution since y = -2x + 7, substitute that for the 2nd y so
-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1
If you use elimination you can subtract the two equations from each other to get rid of the y so
y = -2x + 7
-y = -3x + 8
so 0 = -5x + 15, 5x = 15, x=3
A milk truck is driving around town. What is the volume of the milk truck?
Length: 6
Width: 4
Height: 6
Answer:
[tex]144[/tex] cubic units
Step-by-step explanation:
We can assume that the truck is a rectangular prism since we're given its length, width, and height. To find the volume of a rectangular prism, simply multiply its length, width, and height together. As an algebraic expression, this would be [tex]l*w*h[/tex], where [tex]l[/tex], [tex]w[/tex], and [tex]h[/tex] are the prism's length, width, and height, respectively.
In this case, we are given that [tex]l=6[/tex], [tex]w=4[/tex], and [tex]h=6[/tex]. Therefore, the volume of the milk truck is [tex]6*4*6=144[/tex] cubic units. Hope this helps!
Answer: 144 feet³
Step-by-step explanation: To find the volume, mutiply the Length, Width, and Height. Or we can use the formula.
Rectangular Tank Volume Formula: L x W x H
As we see, 6 is the Length. 4 is the Width and 6 is the Height.
So, we can multiply the Length, Width, and Height to get the volume.
6 x 4 x 6 = 144 feet³
Therefore, the answer is 144 feet³
