Answer:

x=36

Step-by-step explanation:

The angles in a triangle must add to 180 degrees.

Therefore,

x+65+79=180

Add 65 and 79

x+144=180

We want to solve for x. In order to do this, we have to get x by itself. 144 is being added to x (+144)The opposite of addition is subtraction, so subtract 144 from both sides(-144)The +144 and -144 will cancel out, and leave x by itself.

x+144-144=180-144

x=180-144

x=36

Let’s check our answer. Add all the angles together, and make sure they equal 180 degrees.

x+65+79

We know x is equal to 36, so we can substitute it in

36+65+79

180

The 3 angles add to 180, so we know that x=36

Answer:

X=18

Y=52

Step-by-step explanation:

Let X represent the first type of ticket sold at the concert

Let Y represent the second type of ticket sold at the concert-----equation 1

X + Y= 70 (Total number of tickets sold) ------equation 2

(X×10) + ( Y×12)=$804. ( Total money generated in the concert

Since,

X+Y= 70

X= 70-Y

Substitute (70-Y) for X in equation 2

(70-Y)×10 + Y×12=804

700-10Y+12Y= 804

Collect the like terms

700+2Y=804

2Y=804-700

2Y= 104

Divide both sides by the coefficient of Y which is 2

2Y/2= 104/2

Y=52

Substitute 52 for Y in equation 1

X+Y=70

X+ 52=70

collect the like terms

X= 70-52

X=18

Hence the first type of ticket sold is 18 tickets and the second type of ticket sold is 52 tickets.

Answer:

2:50

Step-by-step explanation:

On an ordinary clock, there are 24 hours.

1)  6/24 = 0.25   (The percentage in which the day has passed)

2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50

3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50

The time that is shown in a decimal clock when it is 6 am in the ordinary clock is 2:30 am.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Decimal clock:

One day = 10 hours

Ordinary clock:

One day = 24 hours

6 am is the first quarter of the day.

This means,

There are 4 quarters in a day.

So,

One quarter is 6 hours.

Now,

Number of hours in one quarter in the decimal clock

= 10/4

= 2.5 hours

This means,

2:30 am when it's 6 am in the ordinary clock.

Thus,

The time shown in the decimal clock is 2:30 am.

Answer:

x = 22°

y = 26°

z = 48°

Step-by-step explanation:

∠PQS and ∠QSR is a pair of alternate interior angles

plus PQ is parallel to SR

then

x = 22°

SPR is an isosceles triangle then m∠PRS = 66°

Therefore x + y = 180-(66+66) = 180-132 = 48

then y = 48 - x = 48-22 = 26

finally, z = x + y = 48

Answer:

x = 22

y = 26

z = 48

Step-by-step explanation:

ΔSPR is isosceles, meaning two angles are equal, as indicated.

one base angle is 66, meaning the other one is also 66.

alternate angles are equal ; angle Q = angle S = 22 = x

To find the other angle of the triangle below, add 22 and 66 and subtract from 180 to get 92.

vertically opposite angles are equal ;       92

                                                              88             88

                                                                       92

the triangle on the upper right has 92, 22, and the missing angle which is 66.

the upper left triangle has 88, 66 and the missing which is 26 = y

the straight line above(PQ), now has 66, 66 and the missing one .add , then take away from 180 to get 48 = z

Answer: 96 ft squared ✌️

Step-by-step explanation:

Triangle area is 42 a leg (6) times b leg (14) divided by 2

First rectangle down is 30. Use length times width

Second rectangle down is 14

Last vertical rectangle is 10

Add all areas together

Answer: 96 square feet.

Step-by-step explanation: I would assume you know how to find the area of the rectangles and you are struggling with the triangle. With triangles you take the base or the bottom and multiple it by the width and then divide by 2. In this case the base would be 14 and the width would be 6, so 14x6 is 84 and 84 divided by 2 is 42.

Answer:

a is adjacent, b is opposite, c is the hypotenuse

Step-by-step explanation:

A right angled triangle must contain the opposite, the adjacent and the hypotenuse. The opposite is the side that directly faces the angle of interest. The adjacent is the side that is close to the angle of interest.

Given that the angle Y is positioned between X and Z, the point b becomes the opposite of Y. The point a becomes adjacent to angle Y while c remains the hypotenuse of the right angled triangle.

The image below typifies the explanation given above. It shows the relationship between the three sides of the right angled triangle in detail.

Answer:

Step-by-step explanation:

If [tex]A =\pi xy[/tex], then π, x, and y are all multiplied together. Multiplication is undone by division, so we will divide away the πx to solve for y:

[tex]\frac{A}{\pi x}=y[/tex] which is your last option.

Here, we are required to find an equivalent equation solved for y if the area, a is given by;

a = πxy

An equivalent equation solved for y is;

y = a ÷ (πx)

To find an equivalent equation solved for y,

We have to make y the subject of the formula in;

a = πxy.

Therefore, by dividing both sides of the equation by πx, so that y is left alone on the right hand side.

Therefore, y = a ÷ (πx).

z=6  

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

5(z + 1) = 3(z + 2) + 11

5z + 5 = 3z + 6 + 11

5z + 5 = 3z + 17

5z = 3z + 12

2z = 12

2z/2 = 12/2

z = 6

:)

Answer:

z= 6

Step-by-step explanation:

5(z + 1) = 3(z + 2) + 11

Distribute

5z+5 = 3z+6+11

Combine like terms

5z+5 = 3z+17

Subtract 3z from each side

5z+5-3z = 3z-3z+17

2z+5 = 17

Subtract 5 from each side

2z+5-5 = 17-5

2z = 12

Divide each side by 2

2z/2 =12/2

z = 6

Answer:

60 feet

Step-by-step explanation:

We know that a triangle has 3 sides, in this case we will call them a, b and c.

It tells us that everything is material, it measures 20, that is:

a + b + c = 20

They tell us that she wants to triple each side and to know how much material she would need in total. Then it would be:

border material need = 3 * a + 3 * b + 3 * c

common factor 3:

border material need = 3 * (a + b + c)

border material need = 3 * 20

border material need = 60

Which means that she needs a total of 60 feet of material.

Answer: She would need 60 ft of border material.

Step-by-step explanation: Olga has a triangular flower bed, which means her flower bed is three sided. Also it has been stated that she has 20 feet of border material available. which will fit perfectly around the bed. This also means the perimeter of her flower bed is 20 feet.

Assuming the sides of her flower bed are labeled as a, b and c. Then a plus b plus c would equal 20, since the perimeter is the addition of all sides of the triangle.

However, she intends to triple the length of each side of the flower bed, and that would translate into the sides being 3a, 3b and 3c respectively. This effectively triples the length of the perimeter which is shown as,

Perimeter = a + b + c

20 = a + b + c

3(20) = 3a + 3b + 3c

60 = 3a + 3b + 3c

Therefore, she is going to need more border material and that is calculated as 60 feet.

Answer:

There is 1kg of zinc in 3kg of brass

Step-by-step explanation:

Here, we are interested in knowing the amount of zinc present in 3kg of brass

Brass is an alloy of copper and zinc.

Now to get the amount of zinc present, we have to use the ratio;

The ratio of zinc is 1

So the amount of zinc present is calculated as follows;

Total ratio = 2+ 1 = 3

Thus;

1/3 * 3kg = 1kg
