P and Q form a linear pair if m P=(7x-4) and m Q =(2x-5) find the measure of each angle
Answer:
Answer:
Angle P = 143º
Angle Q = 37º
Step-by-step explanation:
Linear pair means the angles add up to 180º
So, using this, set up the equation: 7x - 4 + 2x - 5 = 180
Combine Like Terms
9x - 9 = 180
Add on both sides
9x = 189
Divide
189/9 = 21
Substitute 21 for x
Angle P: 7(21) - 4
Angle Q: 2(21) - 5

Which of the following are independent events?
randomly choosing a marble from a bag, replacing it, and choosing again reaching into your pocket and pulling out two dimes out of 20 coins
drawing a number from a hat, not replacing it, and then drawing a second number
rolling a number cube, rolling again, and trying to match the first roll
Answer:
randomly choosing a marble from a bag, replacing it, and choosing again
rolling a number cube, rolling again, and trying to match the first roll
Explanation:
In an independent event, getting a certain outcome once does not change the probability of getting the same outcome again.
The second option (about the coins) is NOT independent because if you pull out a dime on your first try, there are fewer dimes in your pocket and you are less likely to pull out a dime the second try. The third option (about drawing a number) is also NOT independent for the same reason: you don't put the number back into the hat after drawing it out, so there's fewer numbers the second time and the probability is different.

Find the area of the shape below?
Answer:
8,910
Step-by-step explanation:
i just multiplied all the sides
and i got 8,910
Answer:
105 cm²
Step-by-step explanation:
The shape is composed of a rectangle and a triangle on the right side
area of rectangle = 15 × 6 = 90 cm²
The triangle has dimensions , base = (15 - 9) = 6 cm and height = (11 - 6) = 5 cm
area of triangle = [tex]\frac{1}{2}[/tex] × 6 × 5 = 3 × 5 = 15 cm²
Total area = 90 + 15 = 105 cm²
Andrew is starting his own snow plowing business. Andrew has calculated that he needs to earn $500 per week to support his family. If he knows he will only be able to work 50 hours per week, what is the minimum amount of dollars per hour that he will need to charge his customers?
Answer:Ten dollars per hour
Step-by-step explanation:
50 hour =500 dollars
1 hour = ?
Using the criss cross method we multiply one hour by five hundred dollars and divide by fifty dollars.
?=(1 hour×500 dollars)/50 hour
?= 500 dollars/50
?=10 dollars per hour
Answer:
$10
Step-by-step explanation:
$500/50= 10
He needs to earn $10 an hour x the 50 hours = $500

Amaka buys 4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils. If a pencil cost #8, how much does a ruler cost?
Answer: ruler cost $12
Step-by-step explanation:
step 1
Let cost of ruler be represented as r
and cost of pencil be represented as p
we were given that
4 rulers and a pencil and these cost the same as 2 rulers and 4 pencils which is expressed as
4r + p = 2r+ 4p
and cost of pencil= $8
therefore
sTEP 2--- Solving
4r+ 8 = 2r+ 4 x8
4r+ 8 = 2r+ 32
4r - 2r= 32-8
2r= 24
r= 24/2 = r= $12

Y=2x-4
X+2y=10
Answer:
([tex]\frac{18}{5}[/tex], [tex]\frac{16}{5}[/tex] )
Step-by-step explanation:
Given the 2 equations
y = 2x - 4 → (1)
x + 2y = 10 → (2)
Substitute y = 2x - 4 into (2)
x + 2(2x - 4) = 10 ← distribute and simplify left side
x + 4x - 8 = 10
5x - 8 = 10 ( add 8 to both sides )
5x = 18 ( divide both sides by 5 )
x = [tex]\frac{18}{5}[/tex]
Substitute this value into (1) for corresponding value of y
y = 2([tex]\frac{18}{5}[/tex] ) - 4 = [tex]\frac{36}{5}[/tex] - [tex]\frac{20}{5}[/tex] = [tex]\frac{16}{5}[/tex]
solution is ([tex]\frac{18}{5}[/tex], [tex]\frac{16}{5}[/tex] )
3. Rectangle J is 6 feet wide and 9 feet long.
Rectangle K is 9 feet wide and 12 feet long.
Are the rectangles similar? Explain.
Answer:
No it's not!
Step-by-step explanation:
because the length (long) of J and K are totally different whereas the breadth(width) of J and K is also different which does make similar in sense

Answer:
[tex]0< b\leq 14.5[/tex]
Step-by-step explanation:
Let's set up our equation. We know that rectangles have two pairs of equal sides. We are also given that one pair of those sides is 1 unit longer than the other pair. Finally, we are told that the perimeter is at most 60 meters. 'At most' tells me to set up an inequality.
I'm going to set up two equations to solve this problem. First, let [tex]a[/tex] be the longer side and [tex]b[/tex] be the shorter side.
[tex]2a+2b\leq 60[/tex]
Next, because the sides are consecutive integers and [tex]b[/tex] is shorter, we can say that [tex]a-b=1[/tex].
We now have a system of equations. I will solve using substitution.
[tex]a-b=1\\a=b+1[/tex]
Substitute [tex]a[/tex] into the first equation.
[tex]2(b+1)+2b\leq 60[/tex]
Solve algebraically.
[tex]2b+2+2b\leq 60\\4b+2\leq 60\\4b\leq 58\\b\leq 14.5[/tex]
So, [tex]b[/tex] could be any integer between 0 (since distance cannot be negative) and 14.5, also written as [tex]0<b\leq 14.5[/tex].

A family of 10 that all leave the house at the same time each morning has two bathrooms. They must share for everyone to be ready. Time is allotted to each family based on age. Is this apportionment or not apportionment?
Answer:
Not apportionment
Step-by-step explanation:
Apportionment can be described as a way of sharing out or dividing out in the best fair method.
If a family of 10 leave the house at the same time and have to share just two bathrooms, the time allocation should not be based on age rather should be based on how early each person wakes up in the morning.
The Grand Old Duke of York had 10 000 men. He lost 10% of them on way to the top of
the hill, and he lost 15% of the rest as he marched them back down the hill.
What percentage of the 10 000 men were still there when they reached the bottom of
the hill?
Answer:
76.5%
Step-by-step explanation:
He lost 10% of them on way to the top of the hill
10% of 10,000 men
= 0.1 * 10,000
= 1,000 men
Remaining men = 10,000 - 1,000
= 9,000 men
15% of the rest as he marched them back down the hill.
15% of 9,000 men
= 0.15 × 9000
= 1,350 men
Total men remaining = 9000 - 1,350
= 7,650 men
% remaining =
x% of 10000 men = 7,650
x/100 * 10,000 = 7,650
Cross product
10,000x =7,650 * 100
10,000x = 765,000
x = 765,000/10,000
= 76.5%
x = 76.5%

One month Sam rented 3 movies and 8 video games for a total of $55 . The next month he rented 5 movies and 2 video games for a total of $18 . Find the rental cost for each movie and each video game.
Answer:
Step-by-step explanation:
You are trying to find the values of two quantities, so you will need to set up a system of two equations in two variables. We'll call M the price of a movie and V the price of a video game.
The first month: 3 movies, 8 video games, $55. Let's translate this into algebra:
3M + 8V = 55
The second month: 5 movies, 2 video games, $18. Translated:
5M + 2V = 18
Solve that system of equations
