= 5 root 2

if my answer helps please mark as brainliest.

Answer:

x = 5*sqrt(2)

y = 5*sqrt(2)

Step-by-step explanation:

Because the triangle is a 45-45-90 triangle, 10 is equal to x * sqrt(2) and x = y.

x = 10 / sqrt(2)

When simplified:

10 / sqrt(2) = (10 * sqrt(2))  / 2 = 5 * sqrt(2)

Answer:

value of QZ = 8 units and QM =  12 units.

Step-by-step explanation:

Given: In triangle PQR has medians QM and PN that intersect at Z.

If ZM = 4 units.

In the figure given below;  second median divided the two triangles formed by the first median in the ratio 2:1.

We have to find the value of QZ and QM;

QZ:ZM = 2: 1

⇒

Substitute the value of ZM =4 units and solve for QZ;

Multiply both sides by 4 we get;

Now, calculate QM;

QM = QZ+ZM = 8 + 4 = 12 units.

Therefore, the value of QZ and QM are; 8 units and 12 units

Answer:

Step-by-step explanation:

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Step 1: Set up a table with quantity and value.

Step 2: Fill in the table with information from the question.

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

Step 3: Add down each column to get the equations

x + y = 350                    (equation 1)

3x + 2y = 950                (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

Answer: 250 $3 tickets and 100 $2 tickets were sold.

Answer:

The answer is attached below.

Answer:

$6.75

Step-by-step explanation:

To find the unit price, just divide the total price ($47.25) by the quantity (7).

[tex]\frac{47.25}{7} = 6.75[/tex]

Answer:

y=3 and x=0

Step-by-step explanation:

3x−3y=−9. i'm going to solve for x.

3x−3y+3y=−9+3y

3x=3y−9

3x/3=(3y-9)/3  to isolate x we have to divide everything by 3

x=y−3

so now that we have x we can substitute it in 4x+4y=12

4(y-3)+4y=12

4y-12+4y=12

8y-12=12

8y-12+12=12+12

8y=24

8y/8=24/8

y=3

we have y which equals 3, so now we can substitute it into any equation so solve for x again.

3x – 3y = -9

3x-3(3)=-9

3x-9=-9

3x-9+9=-9+9

3x=0

3x/3=0/3

x=0

so, final answers are y=3 and x=0

checking our work:

3(0)-3(3)=-9

0-9=-9

-9=-9 true

4(0)+4(3)=12

0+12=12

12=12 true

Step-by-step explanation:

The product of M x N is {4a + 8b + 12c}.

Given are the matrices as -

M = {a, b, c} and N = {4, 8, 12}

We can write the product as -

M x N = {4a + 8b + 12c}

Therefore, the product of M x N is {4a + 8b + 12c}.

Answer:

B

Step-by-step explanation:

It's B

3^5 = 243

so the 5th root of 243 is 3

(x^7)^(1/5) = x^(7/5)

(y^10)^(1/5) = 7 ^(10/5) = 7^2

z^(21)^(1/5) = z^(21/5)

Answer:

the number is 4  

Step-by-step explanation:

Let us assume the number be n

given that

n - 4

Now it is doubled i.e. 2(n -4)

So, the equation is

2(n - 4) = n - 4

2n - 8 = n - 4

n = 4

hence, the number is 4  

[tex] \frac{5}{y} = \frac{5 + 3 }{y + x} [/tex]

[tex]5(y + x) = y( 5 + 3)[/tex]

[tex]5y + 5x = 8y[/tex]

[tex]5x = 8y - 5y[/tex]

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

[tex] \frac{x}{y} = \frac{3}{5} [/tex]

[tex]x = 3[/tex]

[tex]y = 5[/tex]

Answer:

y : x: = 5 : 4

Step-by-step explanation:

x to y = 4 to 5

Rewrite;

x:y = 4:5

Remember, a ratio is another way of representing a fraction, hence one can do the same operations that one could do with a fraction. Therefore, one can take the cross products of a ratio;

x : y= 4 : 5

5x = 4y

Inverse operations;

5x = 4y

x = [tex]\frac{4}{5}[/tex]y

Now substitute this into the equation y:x

y : [tex]\frac{4}{5}[/tex]y

Rewrite as a fraction;

[tex]\frac{y}{\frac{5}{4}y}[/tex]

Simplify;

[tex]\frac{1}{\frac{4}{5}}\\\\\frac{5}{4}[/tex]

Rewrite as a ratio;

y : x = 5 : 4
