Answer:
J(2, 5 )
Step-by-step explanation:
Using the section formula
[tex]x_{J}[/tex] = [tex]\frac{1(-2)+2(4)}{2+1}[/tex] = [tex]\frac{-2+8}{3}[/tex] = [tex]\frac{6}{3}[/tex] = 2
[tex]y_{J}[/tex] = [tex]\frac{1(1)+2(7)}{2+1}[/tex] = [tex]\frac{1+14}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5
Thus J = (2, 5 )
Malik stops at the grocery store to buy a bag of diapers and 2 cans of formula. He spends a total of $37. The next week he stops and buys 2 bags of diapers and 5 cans of formula for a total of $87. How much does a bag of diapers cost? How much is one can of formula?
Answer:
Diapers costs $11 and formula is $13.
Step-by-step explanation:
Let's name diapers as A and formula as B.
Simply the equations:
1A + 2B = $37(1)
2A + 5B = $87(2)
Clear D from one equation.
A = $37 - 2B(1)
Replace D into the other equation.
2*($37 - 2B) + 5B = $87(2)
$74 - 4B + 5B = $87
$74 + B = $87
B = $87 - $74 = $13
Find A, now knowing B.
A = $37 - 2($13)
A = $37 - $26 = $11
Answer:
Cost of a bag of diapers is $11 and cost of one can of formula is $13.
Step-by-step explanation:
Let cost of each diaper = $D and cost of each cans of formula = $C
Malik shops a bag of diapers and 2 cans of formula.
He spends total of $37.
So the equation will be
D + 2C = 37 -------(1)
Next week he stops and buys 2 bags of diapers and 5 cans of formula.
He spends total $87.
Equation for this purchase will be
2D + 5C = 87 ----------(2)
Multiply equation (1) by 2 and subtract it from equation (2).
2(D + 2C) - (2D + 5C) = 2×37 - 87
2D + 4C - 2D - 5C = 74 - 87
-C = - 13
C = 13
From equation (1)
D + 2×13 = 37
D + 26 = 37
D = 37 - 26
D = 11
Therefore, cost of a bag of diapers is $11 and cost of one can of formula is $13.
"The last time I bought this product, it cost $20.00 but it looks like it costs $29.60 today. Why such a large increase?"
Employee: "The cost to make the product increased, so our company decided to increase the price by _______ ."
Answer:
The company decided to increase the price by $9.60, or by 48%.
Step-by-step explanation:
To measure the price difference in dollars is simple, just subtract the old price from the new one:
[tex]29.60 - 20 = 9.60[/tex]
Divide the price change by the old price to find the price increase in percentage:
[tex]9.60 \div 20 = 0.48 \\ 0.48 \times 100\% = 48\%[/tex]
Answer:
Step-by-step explanation:
The last time the customer bought the product it was $20. The price has increased by $9.60.
Subtract the old price from the new one
$29.60 New Price- $20 Old Price=$9.60
Now Divide the Price Change amount of $9.60 by the Old Price $20
$9.60/$20=0.48
0.48X100%=48%

Use the given D to find the range of each function: a f(x)=3x−5, D={−1, 0, 3}
Answer:
Given the domain D = {-1, 0, 3}, the range of f(x) = 3x - 5, is {-8, -5, 4}.
Step-by-step explanation:
To find the range you have to replace the values indicated by the domain in the function (range refers to "y" values of the function).
f(-1) = -8
f(0) = -5
f(3) = 4.
So the range for the given domain is {-8, -5, 4}.
Answer: The required range of the given function is {-8, -5, 4}.
Step-by-step explanation: We are given to find the range of the following function :
[tex]f(x)=3x-5,~~D=\{-1,0,3\}.[/tex]
Since the domain D contains points -1, 0 and 3, so the range will be the following set :
{f(-1), f(0), f(3)}.
We have
[tex]f(-1)=3(-1)-5=-3-5=-8,\\\\f(0)=3\times0-5=-5,\\\\f(3)=3\times3-5=4.[/tex]
Thus, the required range of the given function is {-8, -5, 4}.

One car travels 25 km/h faster than another. In the same time that one goes 120 km, the other goes
220 km. Find their speeds.
Answer:
Speed of first car = 30 km/h and speed of second car = 55 km/h
Step-by-step explanation:
Speed = distance/time
Given: distance travelled by one car = 120 km
Distance travelled by second car = 220 km
Now let speed of first car be x km/h.
∴ Speed of second car = (x + 25) km/h (∵ One car travels 25 km\h faster than another)
Now, if the time is constant, then ratio of distance to speed of first car will be equal to the ratio of distance to speed of another car. e.g.,
[tex]\frac{distance\ travelled\ by\ first\ car}{speed\ of\ first\ car} = \frac{distance\ travelled\ by\ second\ car}{speed\ of\ second\ car}[/tex]
[tex]\frac{120}{x} = \frac{220}{x+25}[/tex]
[tex]220x = 120 (x +25)[/tex]
[tex]220x = 120x + 3000[/tex]
[tex]100x = 3000[/tex]
[tex]x = 30[/tex]
∴ Speed of first car = 30 km/h
Speed of second car = (30 + 25) = 55 km/h.

What does ‘? m/s = 25.2 km/h’ mean and how do you complete it?
Thanks x
Answer:
Answer is 7
Step-by-step explanation:
you can see in above picture
Step-by-step explanation:
This is a unit conversion problem it seems.
Basically, you're trying to take 25.2 km/h and turn that into m/s.
Let's convert hours to seconds first, so you can sort of see what I mean:
[tex]\frac{25.2km}{1 hour}*\frac{1hour}{60 minutes}*\frac{1minute}{60seconds}[/tex]
So now we've done the first part of the equation, dealing with hours to seconds. See how we now have seconds in the denominator instead of hours? (Keep in mind, we don't want to multiply everything until the very very end!)
Now let's turn kilometers into meters (kilo- means thousand):
[tex]*\frac{1000meters}{1kilometer}[/tex]
Now that we have that, let's multiply out the full equation to get our answer!
[tex]\frac{25.2*1000}{60*60} =7[/tex]
Therefore our answer is the nice and satisfying 7.
Answer:

How many times does 27 go into 70?
Answer: 27 can go in completely to 70 twice, or, if you want an exact decimal, 2.5925 (...it goes on and on) times
Step-by-step explanation: what you have to do is divide, 70 divided by 27. What “go into” means is to divide, always. What division does is show how much a number can fit inside another one. For example, 4 divided by two. If four is split into two equal parts, you get two. So four divided by two is two.
The exact same thing is happening in this situation; except with bigger numbers that don’t go into each other evenly.
So, the answer is approximately two or exactly 2.59..
The number 27 goes into 70 a total of 2 whole times when only considering whole numbers. The result of dividing 70 by 27 gives approximately 2.59 if we take decimals into account.
Explanation:The question is asking how many times does 27 go into 70. In other words, this is a division problem where 70 is the dividend (the number being divided) and 27 is the divisor (the number we are dividing by).
To find the answer, we simply divide 70 by 27. Using a calculator, we find that 70 divided by 27 equals approximately 2.59.
However, if we're only counting whole times, we only count the number before the decimal point. Therefore, 27 goes into 70 a total of 2 whole times.

If KM bisects JKL, m JKL = 92, and MKL = (5x+1), find the value of x.
Answer:
x = 9
Step-by-step explanation:
The trick here is knowing that JKM and MKL are equal, which means MKL is equal to JKL/2. From that knowledge, we can solve.
MKL = JKL/2
5x + 1 = 46
5x = 45
x = 9
The value of the x is 9 if KM bisects JKL, m JKL = 92, and MKL = (5x+1).
Since KM bisects JKL, it divides the angle JKL into two congruent angles. Therefore, angle MKL is equal to angle JKL divided by 2.
Given that angle JKL is 92 degrees, we can find the value of x by setting up the following equation:
5x + 1 = 92/2
First, we simplify the right side of the equation:
92/2 = 46
Now, we can solve for x:
5x + 1 = 46
5x = 46 - 1
5x = 45
x = 45/5
x = 9
Therefore, the value of x is 9.

In a bag full of small balls, 1/4 of these balls are green, 1/8 are blue, 1/12 are yellow and the remaining 26 white. How many balls are blue?
Answer:
6
Step-by-step explanation:
First, find common denominators for the fractions given. In this case, it will be 24. Remember that what you multiply to the denominator, you multiply to the numerator:
(1/4) x (6/6) = 6/24
(1/8) x (3/3) = 3/24
(1/12) x (2/2) = 2/24
(6/24) + (3/24) + (2/24) = (6 + 3 + 2)/24 = (11)/24
11/24 of the balls are NOT white.
Find the amount that are white. Subtract 11/24 from the total, 24/24:
24/24 - 11/24 = 13/24
Multiply:
26 * (1/8)/(13/24) = (26/8)/(13/24) = (13/4) * (24/13) = (24/4) = 6
6 is the amount of blue balls there are in the bag.

Hey!
---------------------------------
1/4 are green.
1/8 are blue.
1/12 are yellow.
---------------------------------
Solution:
= 1/4 + 1/8 + 1/12
= 6/24 + 3/24 + 2/24
= 11/24
1 - 11/24 = 13/24
13/24 are white.
13x/24 = 26
13x/24 * 24 = 26 * 24
13x = 624
13x/13 = 624/13
x = 48
To find how many blue balls just divide by 8.
48/8 = 6
