The Bears have won 7 and tied 2 of their last 13 games. They have not forfeited any games. Which ratio correctly compares their wins to losses?
Answer:
7:4
Step-by-step explanation:
7:4 because if 13 is the total amount of games, that minus the amount of games won and tied equals the amount of games loss which is 4. Since it says wins to losses, the wins will come first in the ratio. Therefore the correct answer would be 7:4.
Answer:
7:4

What is the value of y in the equation 9 + y = 8? this is extremely time sensitive
You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y
y=1
Answer: y =-1
Step-by-step explanation:y =-1
Last option is correct.
Step-by-step explanation:
The given equation is
In order to solve for y, we need to isolate y.
In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.
The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation
3) Find two consecutive even integers such that their sum is equal to the difference of 3 times the larger & 2 times the smaller.
What do they mean by the larger and the smaller?
Answer:
In assumption, x is the smaller even integer and x+2 is the next so it will be larger.
The integers are 4 and 6
Step-by-step explanation:
Let the two consecutive even integers be x and x+2
Here x is the smaller even integer and x+2 is the next so it will be larger.
Now according to the given statement
Sum of both: [tex]x+x+2[/tex]
difference of 3 times the larger & 2 times the smaller:[tex]3(x+2)-2x[/tex]
Putting the sum and difference equal:
[tex]x+x+2 = 3(x+2)-2x[/tex]
Solving the equation
[tex]2x+2 = 3x+6-2x\\2x+2 = x+6\\2x+2-x = x+6-x\\x+2 = 6\\x+2-2 = 6-2\\x = 4[/tex]
The next integer will be:
[tex]x+2 = 4+2 = 6[/tex]
Hence,
In assumption, x is the smaller even integer and x+2 is the next so it will be larger.
The integers are 4 and 6.
A 6 pack of Snickers bars costs $5.70.
How much would a 10 pack cost at the same price per bar?
Answer:$9.5
Step-by-step explanation:
Terri is starting a babysitting service to make some extra money. She plans to charge a base fee of $10 plus $7 per hour. Write a function that could be used to represent her total charge for the babysitting service, y, as a function of the number of hours she babysits, x. *
y = 10x – 7
y = 7x – 10
y = 10x + 7
y = 7x + 10
Work Shown:
x = number of hours she babysits
1 hour = 7 dollars
x hours = 7x dollars (multiply both sides by x)
She earns 7x dollars after babysitting x hours if we ignore the $10 base fee. Add on the $10 base fee to get 7x+10 dollars total.
Therefore y = 7x+10 is the equation we want.
Answer:
I thought it would be y=10x+7 because the base fee which is the starting fee is 10 and your adding 7 every hour so that would be +7.

What does it mean for a system of equations to have "no" solution?????
Answer:
when a system of equation has no solution it means that both X's are 0
If it is on a graph then two lines would be parallel to each other
Step-by-step explanation:
for example
-6x +7y= -6x+12y
automatically you would add six to the negative six and you would not have any X's. so it has no solution
-6x +7y= -6x+12y
+6 +6
-------------------
7y=12y
Hopefully you understand what no solution is

Ina certain county weights of women are normally distributed with a mean of 138 lb and a standard deviation of 15 lb. What percentage of women in that country weigh more than 120 lb
Answer:
88.493%
Step-by-step explanation:
We solve this question using z score formula.
Z score = x - μ/σ
where
x is the raw score = 120lb
μ is the population mean = 138lb
σ is the population standard deviation = 15lb
Hence,
z = 120 - 138/15
= -1.2
Probability value from Z-Table:
P(x<120) = 0.11507
P(x>120) = 1 - P(x<120)
1 - 0.11507
= 0.88493
Converting to percentage
= 0.88493 × 100
= 88.493%
The percentage of women in that country weigh more than 120 lb is 88.493%
I need to rearrange the variables to solve for pressure, P, as a function of volume and temperature, V and T. Write out your work on paper and submit a picture.
Answer:
P = (8T) / V
Step-by-step explanation:
P*V=8*T*P/P multiply both sides by P
P*V=8*T because P/P=1
P = 8T/V divide both sides by V

Find the measure of each interior and exterior angle. The diagram is not to scale.
Answer/Step-by-step explanation:
✅m<1 = 90° (right angle)
✅m<2 = 90° (<1 and <2 are supplementary, and also linear pair)
✅m<3 = 90° (<1 and <3 are supplementary, and also linear pair)
✅m<4 = 115° (vertical angles theorem)
✅m<5 + m<4 = 180° (linear pair)
m<5 + 115° = 180° (substitution)
Subtract 115 from each side
m<5 = 180 - 115
m<5 = 65°
✅m<6 = m<5 (vertical angles are congruent)
m<6 = 65° (substitution)
✅m<7 = m<1 + m<6 (exterior angle theorem)
m<7 = 90° + 65° (substitution)
m<7 = 155°
✅m<8 = 180 - m<7 (linear pair theorem)
m<8 = 180 - 155 (substitution)
m<8 = 25°
✅m<9 = m<7 (vertical angles are congruent)
m<9 = 155° (substitution)
8th GRADE MATH NEED HELP I HAVE AN F and my parents r coming at me TY what is the slope for this scenario?
Please help with number 2!
Answers:
D'' = (1, -3)
E'' = (1, -1)
F'' = (3, -1)
G'' = (3, -4)
A diagram is shown below.
========================================================
Explanation:
The center of dilation is point E, which means this point does not move when the dilation is applied. Every other point will move.
As your diagram indicates, segment DE is 4 units long. If we apply the scale factor 1/2, then D'E' will be half as long meaning D'E' = 2. So point D' is 2 units above point E at (1,3)
Point F is 4 units away from point E. The scale factor 1/2 will bring F closer to E leading to segment F'E' = 2. So we'll start at E and move 2 units to the right to land on F ' (3, 1)
From F to G is 6 units, which cuts in half to 3. So from F' to G' is 3 units telling us we start at F ' (3, 1) and go up three units to get go G ' (3, 4)
So far we have
D ' = (1, 3)
E ' = (1, 1) ... fixed point doesn't move
F ' = (3, 1)
G ' = (3, 4)
-------------
From here we'll apply the reflection over the x axis rule which says
[tex](x,y) \to (x, -y)[/tex]
the x coordinate stays the same, and the y coordinate flips from positive to negative (or vice versa).
Based on what was mentioned for D', E', F' and G', we get the following
D'' = (1, -3)
E'' = (1, -1) .... this point does move now
F'' = (3, -1)
G'' = (3, -4)
Points E' and E'' are in different locations because all fixed points in this reflection are along the mirror line y = 0 (aka the x axis). In other words, if E was on the x axis, then it would not move if we applied this reflection.
Check out the diagram below see a visual summary of what happened. Note how the red points moved in closer to point E (since the distances from the center E have been cut in half) compared to the blue counterparts.
