[tex] = 40\%[/tex]
40℅ of the students likes to play tennis
hope this helps you
Answer:
40% Use the ratio method
Step-by-step explanation:
Since
10 : 25 = X : 100
Then we know
10/25 = X/100
Multiplying both sides by 100 cancels on the right
100 × (10/25) = (X/100) × 100
100 × (10/25) = X
Then solving for X
X = 100 × (10/25)
X = 40
Therefore
10 : 25 = 40 : 100

Find the elapsed time.
Start: 11:55 A.M.
End: 5:10 P.M.
Answer:
5 hours and 15 minutes
Step-by-step explanation:
From 11:55 A.M. to 12:00 P.M. is 5 minutes.
From 12:00 P.M. to 12:10 P.M. is 10 minutes.
From 12:10 P.M. to 5:10 P.M. is 5 hours.

Answer:
x=41 et y=131
Step-by-step explanation:
49+x=90
x=90-49=41
---------------------------
y=90+x
y=90+41=131
Answer:
131°
Step-by-step explanation:
take the line with angle 49°
st line angle is 180°
49+90+a = 180 where (a+90=y)
139+a = 180
a = 180-139=. 41°
by opposite angles equal axiom a =x = 41°
y = 131°
(3/8+3/4)−(1/3+1/6) what is the anwser
Answer:
5/8
Step-by-step explanation:
So, let's do the first one first.
You want to make the fraction have the same denominator (bottom number). So, in this case, we have 3/8 and 3/4. If we want them to have the same bottom number, we keep 3/8 how it is, and multiply 2/2 by the 3/4 to get 6/8. So, now we have 3/8 + 6/8. 3/8 + 6/8 = 9/8.
Now, we have 1/3 + 1/6. So, we are going to do the same thing, keep the 1/6, and multiply 1/3 by 2/2, so that the bottom number is equal to the other fraction's bottom number. So, 1/3 x 2/2 = 2/6. Now, we have the equation 2/6 + 1/6. 2/6 + 1/6 = 3/6.
Now, we have this final equation: 9/8 - 3/6. So, now we need to find the denominator that both of them can deal with. So, in this case, we can do 24.
9/8 x 3/3 = 27/24
3/6 x 4/4 = 12/24
Now, we subtract:
27/24
- 12/24
_______
15/24.
Now, we simplify.
15 divided by 3 = 5.
24 divided by 3 = 8
So, 5/8 is our final answer.

Circle T is defined by the equation (x + 5)2 + (y - 2) = 81. Which of the following shows the location of the center of Circle T and the radius of this
circle?
A T is located on (-5, 2); radius = 9 units
B T is located at (5,-2); radius = 9 units
C T is located at (-5, 2); radius = 81 units
D T is located at (5,-2); radius = 81 units
Answer:
A) T is located on (-5, 2); radius = 9 units
Step-by-step explanation:
eqn of circle= (x-a)^2 + (y-b)^2 = r^2
where (a,b) is centre of circle.
(x+5)^2 = (x - (-5) )^2
(y-2)^2 = (y - (2) )^2
(-5,2)
r^2 =81
r = sqrt of 81
r = 9

Is the first step in solving different from the first step of solving ? Explain Yes, in the first equation, start by subtracting 8 from both sides to set the equation equal to zero, but in the second equation, start by adding 1 to both sides to isolate the radical. Yes, in the first equation, start by squaring both sides to eliminate the radical, but in the second equation, start by adding 1 to both sides to isolate the radical. No, to solve either equation, square both sides to eliminate all radicals. No, to solve either equation, isolate the radical by adding 1 to both sides.
The first step in solving the first equation is different from the first step of solving the second equation because,
In the first equation, start by squaring both sides to eliminate the radical, but in the second equation, start by adding 1 to both sides to isolate the radical.
Thus the option B is the correct option.

Nick recently started a landscaping company. He began with 3 clients. Thanks to word-of-mouth referrals, his clients double each month.
How many clients will Nick have after one year?
Answer:
12288
Step-by-step explanation:
In terms of exponential growth and decay, you would start by putting it into the formula, "f(x)=a⋅b^x". You'll put 3 as a and since it's increasing double (or 100%) each month, you'll put b as 2 since you need to add one unit. For ^x, you'll add 12 since there are 12 months in a year. Your completed formula would come out as 3(2)^12 which would come out to 12288.

7x − 10y = 17
Answer:
y = -8

Answer: x = 6
Step-by-step explanation:
Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.
Next, we set up the proportion as follows:
[tex]\frac{21}{x+3} =\frac{7}{3}[/tex]
Then, you cross multiply to get the equation:
[tex]63=7x+21[/tex]
After solving down algebraically, you get the value of x to be 6.

B. 2x + 4y
Step-by-step explanation:
If x = 4, and y = 7, let's substitute these values for x and y in the equations!
For A, the equation is 2xy. Substitute the values and you have 2(4)(7) which equals 56. This expression is incorrect since the expression doesn't equal 36.
For B, the equation is 2x + 4y. Substitute and you get the equation
2(4) + 4(7) → 8 + 28 = 36.
36 is your desired value, and you get that with the expression 2x + 4y.

A. 56

Solve for x and y
6/x+2y + 5/x-2y = -3 ;
3/x+2y + 7/x-2y = -6
Step-by-step explanation:
Let
{1/(x+2y)} = u -----Eqn(1)
{1/(x-2y)} = v ------Eqn(2)
So, given equation can be rewritten as
⇛6u + 5v = -3 ---Eqn(3)
⇛3u + 7v = -6 -----Eqn(4)
On multiply equation (4) by 2, we get
⇛6u + 14v = -12 -----Eqn(5)
On subtracting equation (3) from equation (5), we get
⇛9v = -9
⇛v = -9/9
⇛v = -1 ----Eqn(6)
Put value of v in equation (3), we get
6u + 5v = -3
⇛6u + 5 * (-1) = -3
⇛6u -5 = -3
⇛6u = -3 + 5
⇛6u = 2
⇛u = 2/6
⇛u = (2÷2)/(6÷2)
⇛u = 1/3 -----Eqn(7)
Now, substituting value of u and v in equation (1) and equation (2), we get
{1/(x+2y)} = 1/3 and {1/(x-2y)} = -1
⇛x + 2y = 3 -----Eqn(8)
⇛x - 2y = -1 -------Eqn(9)
Now, add equation (8) and equation (9) , we get
⇛2x = 2
⇛x = 2/2
⇛x = 1 -----Eqn(10)On substituting x = 1 in equation (8), we get
x + 2y = 3
⇛ 1 + 2y = 3
⇛2y = 3 - 1
⇛2y = 2
⇛y = 2/2
⇛y = 1 ------Eqn(11)Therefore, x = 1 and y = 1
Answer: Hence the value of x and y is 1 and 1.
