Answer:
between 17 and 18
Step-by-step explanation:
x² = 315
To find the range that the value is in, you need to know the perfect squares before and after 315.
17² = 289
18² = 324
289 < 315 < 324
This means √315 is between 17 and 18.

Nancy has a pool in her backyard, and she wants to build a fence around the entire area,
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?
Submit
Since Nancy wants a fence around her backyard, we are obviously talking about perimeter here.
10 + 10 + 15 + 15 = 50
The perimeter of her backyard is 50 meters
50 x 10 = 500
It would cost her $500

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
(i think there might of been a mistake in the question lol)
Sam cut a 28-foot rope into 4 equal pieces. How long is each piece of rope in inches? -HELP PLEASE THIS IT DUE IN 5 MINUTESSS
Answer:
84 inches
Step-by-step explanation:
12 inches are in 1 foot, so you take the number of feet (28) and multiply by the number of inches in a foot (12)
28×12=336 (inches)
then you take 336 and divide by 4 to get your 4 equal pieces.
336 divided by 4 = 84, 84 inches
A sequence has an initial term a1=22 and a recursive formula an=an−1−10.
What is the explicit formula for the sequence?
an=22+10(n−1)
an=22−10(n−1)
an=10−22(n−1)
an=10+22(n−1)
Answer:
B. aₙ = 22 - 10(n - 1)Step-by-step explanation:
Recursive formula:
a₁ = 22aₙ = aₙ ₋₁ - 10Common difference is d = -10Explicit formula:
aₙ = a₁ + (n - 1)d = 22 + (n - 1)*(-10) = 22 - 10(n - 1)Correct choice is B

How many more dollars will Jacob earn on each skateboard deck if he switches to the new material? Explain how you found your answer.
Answer:
$5
Step-by-step explanation:
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.

If the the diagonals of A parallelogram or perpendicular but not congruent is the parallelogram a 1. rectangle 2. square 3. rhombus or 4. Parallelogram
9514 1404 393
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.

What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
We have,
A dice is thrown.
So, the chances of getting 2 is 1/6

Ana es una vendedora de bombones tenía 295 cajas y ha vendido 67 de ellas si cada caja contiene 24 bombones¿ cuántos bombones le quedaron sin vender?
Answer:
the number of chocolates remains unsold is 5,472
Step-by-step explanation:
The computation of the number of chocolates remains unsold is given below:
= (Total boxes - sold boxes) × number of chocolates in each box
= (295 - 67) × 24
= 228 × 24
= 5,472 chocolates
hence, the number of chocolates remains unsold is 5,472

The values of x are x = -3 ,5 and [tex]x = \frac{-1}{11}[/tex]
Step-by-step explanation:
Step(i):-
Given that the function
y = (x+3)⁴(x-5)⁷ ...(i)
Apply UV formula
[tex]\frac{dy}{dx} = U^{l} V+ U V^{l}[/tex]
Differentiating equation (i) with respective to 'x ', we get

Step(ii):-
Given that
[tex]\frac{dy}{dx} = 0[/tex]
[tex](x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3} =0[/tex]
[tex](x+3)^{3}(x-5)^{6} (7(x+3)+4(x-5))[/tex] =0

After swimming 60 feet below the surface of water, a whale swims up 30 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water service.
A. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
B. The equation is -60 + (-30) = -30. The whale is 30 feet below the water surface.
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface.
D. The equation is -60 + 30 = -90. The whale is 90 feet below the water surface.
Answer:
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface
Step-by-step explanation:
At the surface of the water in the swimming pool, the height of elevation is 0.
Thus, if you swim 60 ft below the surface, it means you are going in the negative direction when we consider a number line. Thus, distance = -60 ft
Now, when you swim back up by 30 ft, it is in the positive direction. Thus, total distance is now; -60 + 30 = -30 ft
Thus value denotes a negative direction and it means you are 30 ft below the surface of the water.

Step-by-step explanation:
If k is the midpoint of, jk=11x-7 and kl=6x+2, find jl
Answer:
JL = 118/5
Step-by-step explanation:
Because K is the midpoint, we know that JK and KL are going to equal each other because of the Segment Addition Postulate.
JK + KL = JL
So we know that JK = 11x-7 and KL = 6x+2
Now, we solve for X.
11x-7 = 6x+2
In order to get X alone, we must get the X's all to one side and the numbers to one side.
11x-7 = 6x+2
+7 +7
11x = 6x + 9
-6x -6x
5x = 9
x = 9/5
Now, we plug X into the equations.
JK = 11x - 7
JK = 11(9/5) - 7
JK = 99/5 - 7
JK = 64/5
KL = 6x + 2
KL = 6(9/5) + 2
KL = 54/5
Now, we add the numbers (fractions, really) together so that we can get the whole value of the line.
64/5 + 54/5 = 118/5

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:
2(7b + a)
Step-by-step explanation:
to factorize u should take the hcf of both number and put it outside the bracket. if u solve it u can see that 2(7b + a) also equals to 14b + 7a when u use distributive property

Convert –2y2 + x – 4y + 6 = 0 into standard form.
x = 2(y + 1)2 – 6
x = 2(y + 1)2 – 8
x = 2(y + 1)2 – 7
x = 2(y + 1)2 + 8
Answer:A
Step-by-step explanation:
X=2(y+1)^2-6
The equation in the standard form is x = 2(y + 1)² – 8. Then the correct option is B.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have
Convert –2y² + x – 4y + 6 = 0 into standard form.
Simplify the equation, we have
x = 2y² + 4y – 6
x = 2(y² + 2y) – 6
x = 2(y² + 2y + 1) – 2 – 6
x = 2(y + 1)² – 8
Then the correct option is B.
