Nancy's backyard is 10 meters wide and 15 meters long. It costs $10.00 per meter to install
a wooden fence. How much would it cost to put a wooden fence around Nancy's backyard?

Choose the solution to this inequality. 43< − 8/3 y
Since there is a negative on the y term, we need to get rid of that and thus flip the sign at the same time. Getting.
-43>8/3y
Now we just need to divide 8/3 on both sides dividing 8/3 on left can also be written as *3/8
-43*3/8>y
Now flip this entire equation
y<-43*3/8
y<-129/8
If your teacher want you to calculate just divide the fraction, but I recommend not to if your teacher don't ask for it and just leave it this way.
Hope it helps! :D
You have a total of 52 dimes and quarters. You have 10 more quarters than dimes. Which system of
equations can you use to find the number z of quarters and number y of dimes you have? Use the system to
determine how much money you have in quarters and dimes.
9514 1404 393
Answer:
z + y = 52; z - y = 10; z = 31; y = 21; $9.85 total
Step-by-step explanation:
The variables are defined in the problem statement. The equations could be ...
z + y = 52 . . . . . . total number of coins
z - y = 10 . . . . . . . 10 more quarters than dimes
These equations can be solved by adding them together.
(z +y) +(z -y) = (52) + (10)
2z = 62 . . . . . . . simplify
z = 31 . . . . . . . . . divide by 2
31 -10 = y = 21 . . . . find the number of dimes
There are 31 quarters and 21 dimes.
The value of the coins is ...
31($0.25) +21($0.10) = $7.75 +2.10 = $9.85

Answer:
8Step-by-step explanation:
Given the expression 3 * 2 2/3
This can also be expressed as;
3 * 2 2/3
= 3 * 8/3
= (24/3)
= 8
hence the product of both numbers is 8
The equivalent value of the fraction is A = 8
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be represented as p
Let the second number be represented as q
Now , A = pq
when the value of p = 2 2/3
And , when the value of q = 3
On simplifying the equation , we get
A = ( 2 2/3 ) / ( 3 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 2 2/3 ) / ( 3 )
A = ( 2 2/3 ) / ( 3 )
A = ( 8/3 ) / ( 3 )
On simplifying , we get
Multiply by 3 on the fraction , we get
A = ( 8 x 3 ) / 3
A = 8
Therefore , the value of A = 8
Hence , the fraction is A = 8

Answer:
3. rhombus
Step-by-step explanation:
If the diagonals are perpendicular, adjacent sides are congruent. If adjacent sides of a parallelogram are congruent, it is a rhombus.

Diagonals are congruent in a rectangle or square, so those choices don't apply. In a general parallelogram, the diagonals may not be perpendicular.

32-27 = 5
because he was earning 27 per skate board, that function shows him earning 32 per skate board which is an increase of $5.
For 60 points and brainliest Guy’s Gym charges a one time fee of $100 plus $5 per month. Bob’s Gym charges a one time fee of $160 plus $8 per month. After how many months will both gyms charge the same amount?
Answer:
-20
Step-by-step explanation:
They're never going to be the same because Bob's Gym starts at a higher number and also increases by a larger number
Answer:
-20 months lol
Step-by-step explanation:
so the first step to this is to create and equation for each
for guys gym the equation would be 5x+100 and for bob's gym the equation would be 8x+160
because we want them to equal each other we write the equation
5x+100=8x+160 and solve for x to see how many months it will take for the gyms to charge the same amount
step 1 subtract 100 from each side
5x=8x+60
step 2 subtract 8 from each side
-3x=60
step 3 divide each side by -3
x=-20 it will take -20 week for them to charge the same amount

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A lacrosse goalie saved 9 of 12 shots. How many additional consecutive saves must the goalie make to raise his percentage to 0.850?
he would have to take 8 more shots.
Step-by-step explanation:
9saves divided by 12 shots = .75
if you keep adding a shot and a save each time, you get to 17saves divided by 20shots=.85.
Hope this helps!
The percentage can be determined by multiplying the fraction to 100. In order to raise his save percentage to 0.850 goalie has to make one additional save.
Given that,
The number of shots saved out of 12 = 9.
Save percentage = (number of saves ÷ number of shots faced)
In the given case save percentage is as below,
= 9 ÷ 12
= 0.75
Suppose the number of saves to increase the save percentage to 0.85 be N.
Then as per the question,
0.85 = N ÷ 12
=> N = 12 × 0.85
=> N = 10
Thus, the number of additional saves is given by 10 - 9 = 1.
Hence, goalie must make one additional save to raise his percentage to 0.850.

Factor the following expression: 14b + 7a.
Answer:
7(a+2b)
Step-by-step explanation:
To factor an expression, you want to find the greatest common factor (GCF). I know that 7 can go into both 14 and 7, so my GCF would be 7. If I divide both 7a and 14b by 7, I get a and 2b. This means that my answer would be 7(a+2b) as that simplifies to 7a+14b. Hope that was helpful!
Answer:

A quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days, to the nearest hundredth? please help
Answer:
7569.36
Step-by-step explanation:
Given that a quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days,
First convert 1.25 days to hours
1.25 × 24 = 30 hours
Using exponential equation
N = No ( 1 - R% )^t
Where N = new value of the quantity
No = initial value
R = rate
t = time
N = 7800 ( 1 - 0.001 )^30
N = 7800 ( 0.999 )^30
N = 7800 × 0.97043
N = 7569.36154
N = 7569.36 to the nearest hundredth.
Therefore, the value of the quantity after 1.25 days is 7569.36

The force made by a magnet is special because it can make other magnets and some metal objects _______ without ever touching them. A. disappear B. melt C. explode D. move Reset Submit
Here we want to study the magnetic force due to a magnet, we will see that the correct option is D, move.
What is a magnetic field?Magnets create a magnetic field around them, such that any object inside that field is affected due to that field (you can think that the magnet is submerged in this magnetic field that is in the space around it).
The magnetic field affects other magnetized objects (such as magnets) repulsing or attracting them, depending on the polarization (opposite polarizations attract and equal polarizations repel)
With that in mind, the property of the magnetic force is that it can move another magnet without touching them, thus the correct option is D, move.
