5(z + 1) = 3(z + 2) + 11 Solve for Z
Answer:
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

The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y? y = a · πx y = a + (πx) y = a – πx y = a ÷ (πx)
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).

Instead of asking one parent like the father, she should ask both types of parents. Some parents go the mall by themselves not with their spouse. The parents may even have their own separate car so she needs to ask both of them.
In the late 18th century, a decimal clock was proposed, in which there were 100 'minutes' in one 'hour' and 10 'hours' in one day. Assuming that such a clock started from 0:00 at midnight, what time would it show when an ordinary clock showed 6am?
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.
What is an expression?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.

Step-by-step explanation:
On the coordinate plane
The bleachers is 1.5 units to the right and 2 units up.
1.5 units to the right indicates a positive value on the x-axis. Therefore, the bleachers x-coordinate is 1.5.
2 units up indicates a positive value on the y-axis. Therefore, the bleachers y-coordinate is 2.
Therefore, we can write the bleachers location in the (x,y) coordinate system as: (1.5,2)

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.

Greatest common factor of 50c6 and 16c5
Answer:
2c^5 is the greatest common factor.
Step-by-step explanation:
I believe you meant 50c^6 and 16c^5. c6 and c5 have no meaning. c^6 and c^5 are the sixth and fifth powers of c, respectively.
What do the two terms of 50c^6 and 16c^5 have in common? c^5 is common to both c^6 and c^5, and so, if we factor out c^5, we get:
c^5(50c + 16).
Note that 50c and 16 have only 2 as their common factor: 2(25c + 8). Thus, the final factored form of 50c^6 and 16c^5 is 2c^5(25c + 8).
2c^5 is the greatest common factor.

Brass contains copper and zinc in the ratio 2:1. How much zinc is there in 3 kg of brass
plz need help with this plzz
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

If an odd number is greater than 1 and less than 10, then it has no other factors than 1 and itself.
Answer:
The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.
Step-by-step explanation:
There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.
For 3:
[tex]\frac{3}{1} = 3\\\frac{3}{3} = 1[/tex]
Therefore 3 is not a counter example to the statement, because it behaves as stated.
For 5:
[tex]\frac{5}{1} = 5\\\frac{5}{5} = 1[/tex]
Therefore 5 is not a counter example to the statement, because it behaves as stated.
For 7:
[tex]\frac{7}{1} = 7\\\frac{7}{7} = 1[/tex]
Therefore 7 is not a counter example to the statement, because it behaves as stated.
For 9:
[tex]\frac{9}{1} = 9\\\frac{9}{3} = 3\\\frac{9}{9} = 1\\[/tex]
Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.

solve for x in the triangle below. round you answer to the nearest tenth.
Answer:
x ≈ 6.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] ( multiply both sides by 10 )
10 × sin40° = x , thus
x ≈ 6.4 ( to the nearest tenth )

Olga is putting a border around her triangular flower bed. She has 20 feet of border material, which will fit perfectly around the bed. She wants to make the flower bed larger by tripling the length of each of its sides. How much border material will she need in total?
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.
