Answer: So the trick I was taught to use was PEMDAS which stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You solve the parenthesis first, followed by exponents if there are any. Multiplication and division are equal. So if there's multiplication and division in the problem, you solve the one closest to the left or start of the equation first. The same rules apply for addition and subtraction. They are both equal so you solve the first one first, even if the subtraction is before the addition.

Finding angles in measures using triangles
you can use this for help:
the interior angles of a triangle add up to 180°
So, Angle I + angle H + angle x =180°
60°+56°+x°=180°
116°+x°=180°
X=180-116
X=64°
In a ten pin bowling the highest possible score in a single game is 300. At one point in the season, John had an average score of 177. In his next game he obtained a score of 199 which caused his average to increase to 178. After one more game John would like his average to be 183. is it possible for him to accomplish this. If so what score does he need to make his next game if not explain why not.
Answer:
John need to get 293 in his next game to bring his average up to 183.
Step-by-step explanation:
John starts with N games played and averaging 177 points per game.
In game N+1, John scored 199 points.
[tex]\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\[/tex]
So, John has now played (N+1) = 22 games.
We need to know what score John needs in game 23 to bring his average to 183.
[tex]\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\[/tex]
Find the distance between the two points G(-1,-5) and H(3,-8)
Answer:
5.099
Step by step explanations:
Input Data :
Point 1(xA,yA)(xA,yA) = (4, 3)
Point 2(xB,yB)(xB,yB) = (3, -2)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(3−4)2+(−2−3)2(3-4)2+(-2-3)2
= √(−1)2+(−5)2(-1)2+(-5)2
= √1+251+25
= √2626 = 5.099
Distance between points (4, 3) and (3, -2) is 5.099

The pair of points lies on the same line with the given slope. Find x.
(5,8). (x,14); slope = 2
Find x.
(Type an integer or a simplified fraction.)
Answer:
required Value of x is x=8
Step-by-step explanation:
We are given two points: (5,8) and (x,14) and slope =2 . We need to find value of x.
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given slope =2 , x₁=5, y₁=8, x₂=x, y₂=14
So, we actually need to find value of x₂. Putting values in formula and find value of x
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\2=\frac{14-8}{x-5}\\Solving:\\2(x-5)=6\\2x-10=6\\2x=6+10\\2x=16\\x=\frac{16}{2}\\x=8[/tex]
So, required value of x=8
Find the value of x that makes m ∥ n .
Answer:
60
Step-by-step explanation:
(2x+15)=135 They're corresponding angles so they equal/congruent
-15 -15 Subtract 15 on both sides since you're looking for x
2x = 120 Bring down the remains and subtract 135 from 15
2 2 Add 2 on both sides
x= 60 Divide.

Step-by-step explanation:
If 2/5 of the books in the library are fiction and 1/4 of the fiction books are science fiction, what fraction of the books in the library are science fiction? check all that apply.
A. 2/5
B. 1/4
C. 4/7
D. 3/7
None of the provided options match the correct fraction. The correct fraction is 1/10, which is not listed.
Let's calculate the fraction of science fiction books in the library based on the given information.
If 2/5 of the books in the library are fiction, then the fraction of fiction books in the library is 2/5.
Now, if 1/4 of the fiction books are science fiction, we can find the fraction of science fiction books in the library by multiplying the fraction of fiction books by 1/4:
Fraction of science fiction books = (2/5) * (1/4)
Fraction of science fiction books = 2/20
Simplifying the fraction, we get:
Fraction of science fiction books = 1/10
So, the fraction of books in the library that are science fiction is 1/10.
None of the provided options match the correct fraction. The correct fraction is 1/10, which is not listed.

Step-by-step explanation:
A chemical company makes up batches of copper sulfate solution by adding 250 kg of copper sulfate powder to 1000 liters of water. A laboratory chemist wants to make a solution of identical concentration, but only needs 350 mL (0.35 liters) of solution.
How much copper sulfate powder should the chemist add to the water? Enter your answer in the box below in decimal format.
The mass of copper sulfate that the chemist should add is______
kg.
help me please
Answer:
0.07 kgStep-by-step explanation:
Assuming copper sulfate has same density as waterChemical to water ratio as per given is:
250 kg : 1000 liter = 1 kg : 4 literLab solution is 350 ml
Converting to same ratio as above:
350/(1 + 4) = 70 ml
70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 mlAnswer is 0.07 kg

In Allentown, Pennsylvania, there are two hamburger shops, Jenny's Burgers and the Burger Hut. Jenny's Burgers sells a record 36 burgers in 5 hours. The next day, Burger Hut broke the record for 108 burgers in 5 hours. How many times more is the record of Burger Hut then Jenny's Burgers?
How do you know?
Answer: the record is 3 times higher
Step-by-step explanation:
The record Jenny's Burgers sold was:
36 burgers in 5 hours
The record Burger Hut sold was:
108 burgers in 5 hours
We have to divide the record of Burger Hut by Jenny's Burgers.
108 divided by 3 is 36.
So, the record is 3 times higher. Hope this helps!
Answer:
3 times the quantity
Step-by-step explanation:

Step-by-step explanation:
The probability that Terry buys a sandwich is 0.4.
The probability that Terry gets the bus is 0.9.
Assuming the events are independent, what is the probability that Terry buys a sandwich and gets the bus?
Answer:
The probability that Terry buys a sandwich and gets the bus is 0.36
Step-by-step explanation:
When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.
Let A be the event that Terry buys a sandwich
Let B be the event that Terry gets the bus
Then
[tex]P(A) = 0.4\\P(B) = 0.9[/tex]
When two events are independent, their probabilities are multiplied i.e.
[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]
Hence,
The probability that Terry buys a sandwich and gets the bus is 0.36
