Answer:

The answer is 1) aka no solution

Step-by-step explanation:

since isosceles has 2 equal sides we can add two to the shorter side

so now we multiply by 4

8 for short sides each

20 for long side

The longest side of the isosceles triangle is 20 units.

An isosceles triangle in geometry is a triangle with two equal-length sides. It can be specified as having exactly two equal-length sides or at least two equal-length sides, with the latter definition including the equilateral triangle as an exception.

Given that the perimeter of an isosceles triangle is 36 centimetres and two sides of the triangle are in the ratio $2:5.$.

The length of the longest side will be calculated as;-

2S + B = 36

S / B = 2 / 5
S = ( 2B ) / 5

2 x ( 2B ) / 5 + B = 36

4B + 5B = 180

9B = 180

B = 20 units

The measure of the other side is,

S = 2B / 5

S = ( 2 x 20 ) / 5 = 8 units

Hence, the length of the longest side is 20 units.

Step-by-step explanation:

Answer:

shift the decimal point to the left two places.

Step-by-step explanation:

Example:

25%

=0.025

Largest possible value of b is:

75

we are given that:

ab=1200

where a is an integer and b is an odd integer.

we know that product of odd numbers is always odd.

Now, 1200= 12×100

               = 2×6×10×10

              =2×2×3×2×5×2×5

It cannot be factorized further

Now, considering the product of all odd numbers

=3×5×5

=75

Now, if we multiply any other remaining number from the factorization of 1200, we will get a even number

Hence, The largest possible value of b is:

75

Answer:

C. 1 in 2

Step-by-step explanation:

even numbers are 0, 2, 4, 6 etc.
the even numbers in a number cube are
2, 4, 6
so there is 3 possible results
all the numbers in the number cube are 6 numbers
so it is 3/6 times we can get an even number
by simplifying 3/6 (dividing by 3) we get 1/2

Step-by-step explanation:

7+8+10=25cm is the possibile perimeter of this

triangle.

What is system of equation?

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Given information-

Johann bought 3 blue marbles and 5 green marbles.

The total money paid by the Johann is $11.

Marta bought 4 blue marbles and 2 green marbles.

The total money paid by the Marta is $10.

Suppose the price of the blue marbles is [tex]x[/tex] and price of the green marbles is [tex]y[/tex].

As Johann bought 3 blue marbles and 5 green marbles and paid $11. Thus,

[tex]3x+5y=11[/tex]      .....1

Let the above equation is equation number 1.

As Marta bought 4 blue marbles and 2 green marbles and paid $10. Thus,

[tex]4x+2y=10[/tex]      .....2

Let the above equation is equation number 2.

Thus the equation 1 and 2 are the required set of the equation for the given problem.

Hence the system of equations can be used to find the prices of the blue and green marbles are,

[tex]3x+5y=11[/tex]

[tex]4x+2y=10[/tex]

Thus the option 2 is the correct option.

We're given

[tex]\displaystyle \int_4^{-10} g(x) \, dx = -3[/tex]

which immediately tells us that

[tex]\displaystyle \int_{-10}^4 g(x) \, dx = 3[/tex]

In other words, swapping the limits of the integral negates its value.

Also,

[tex]\displaystyle \int_4^6 g(x) \, dx = 5[/tex]

The integral we want to compute is

[tex]\displaystyle \int_{-10}^6 g(x) \, dx[/tex]

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is

[tex]\displaystyle \int_{-10}^6 g(x) \, dx = \int_{-10}^4 g(x) \, dx + \int_4^6 g(x) \, dx = 3 + 5 = \boxed{8}[/tex]

Answer:

y = -x + 2

Step-by-step explanation:

Lines that are parallel have the same slope but different

y-intercepts.

So the slope of the parallel line is -x

We can input the x and y points given to solve for the new y-intercept

The new line is y = -x + 2. Since these two lines are the same, they are coinciding lines.

-Chetan K

Answer:

y = - x + 2

Step-by-step explanation:

y = m x + c

Here,

m ⇒ slope

c ⇒ y - intercept

Let us solve now.

( -6 , 8 ) ⇒ ( x , y )

y = m x + c

8 = -1 × -6 + c

8 = 6 + c

8 - 6 = c

2 = c

y = m x + c

y = - x + 2
