Answer:

40%

Step-by-step explanation:

➡6/15×100

➡600/15

➡40%

Answer: 40% of the plants are carrots

Step-by-step explanation:

In order to figure out the percentage, we have to find what "part" of the "total" are the carrots, which is given. We already know that 6 of the total 15 plants are carrots. When referring to a percentage, basically we are trying to find out how many carrots there would be, if we were to have 100 plants. So, in order to do so, we would need 100 plants. I'll make it even more simple:

We have 15 plants - 6 of which are carrots

If we were to have

100 plants         - HOW MANY would be carrots??

The answer to our question is also the percentage we are looking for. If we replace HOW MANY with x, than we would have this equation: 15*x=6*100, so 15x=600 and x=40, so the percentage is 40%.

In order to make this easier, as i said in the beginning we are referring to the part of a total, with given numbers, so if we would divide 6 out of 15, we would have 6/15=0.4 , multiplying that number with 100 (for the percentage), you get 40% again, with a faster and easier way. Practice makes perfect.

Mean number of tickets sold by boys =

Total Number of tickets sold / Number of boys

=

[tex] \frac{(1 \times 4) + (2 \times 3) + (4 \times 1) + (12 \times 1) + (13 \times 1) + (15 \times 3) + (14 \times 2}{4 + 3 + 1 + 1 + 1 + 3 + 2} \\ = \frac{4 + 6 + 4 + 12 + 13 + 45 + 32}{15} \\ = \frac{116}{15} \\ = 7.73(nearest \: hundredth)[/tex]

Answer:

$667.51

Step-by-step explanation:

610.99 times .0925 is 56.516575. 56.516575 plus 610.99 is 667.506575. That rounded to the nearest cent is 667.51.

Answer: the cost plus tax would be 667.51

The sales tax comes to a total of 56.52

Answer:

144cm^3

Step-by-step explanation:

1) split the figure so you can find the volume of two rectangular prisms.

2) Find the volume of the first rectangular prism with the measurements of 2,       5, and 8. So the volume is 80

3) Find the volume of the second rectangular prism with the measurements of 4, 2, and 8. So you have 64

4) Add the two values 80+64.

5) Then that's your answer; 144

Hope this helps! :D

Answer:

y = -2x+3

Step-by-step explanation:

Hard for me to explain through typing but others will say if its right or wrong.

Answer:

The slope equals the rise divided by the run: . You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it.

Answer:

the slope of the line​ is 1

Step-by-step explanation:

The line goes  1 up, 1 right, 1 up 1 right ........

1 divided into 1 = 1

Q2:

Answer=170.8 sq.ft

Answer:

50

Step-by-step explanation:

To answer this we need to use the PEMDAS strategy, first solve any questions in parentheses, next solve all multiplication and division problems from left to right. Next, solve all addition and subtraction problems from left to right.

36 + (12 - 8) + 2 × 5​

36 + 4 + 2 x 5

36 + 4 + 10

Answer:

y = 2x

Step-by-step explanation:

Total distance walked = y

Number of trips = x

Lily walks 2 kilometers during each trip to school

Equation that shows the

relationship between the number of trips x and the total distance walked y:

y = 2x

For example, if the number of trips (x) is 3

Total distance walked,y = 2(3)

y = 6 kilometers

Answer:

10

Step-by-step explanation:

Remark

Technically, we can't. We have no way of knowing what kind of figure we are working with. We can say to you that if this is not at least a parallelogram then no answer is possible.

Opposite sides of a parallelogram are equal.

Equation

2x = x + 5                  

Solution

Subtract x from each side

2x - x = 5

x = 5

HE = 2x

HE = 2*5

HE = 10

Answer:

y = 6

Step-by-step explanation:

y varies directly with x

y = k*x

Where,

k = constant of variation

Find y when x = 2 and constant of variation,k =3

y = k*x

y = 3 * 2

y = 6

Check:

if y = 6 and x = 2, find k

y = k*x

6 = k*2

6 = 2k

k = 6/2

k = 3

Answer:

z = 8

Step-by-step explanation:

All angles inside a triangle add up to 180 so:

90 + 40 + 5z + 10 = 180

5z + 140 = 180

5z = 40

z = 8

Answer:

4y² + 5y - 3

Answer: 23

Step-by-step explanation:

Answer:

15 + 4x = 40

Step-by-step explanation:

To construct this equation, we'll list all the values we will include first.

The total fee equals $40, so we'll put 40 on one side of the equation.

On the other side, we have to put the values that make up the total. The fee is made with the project cost plus the hourly rate. The first part of this is the beginning cost, $15. Added to this is the hourly cost, $4, times the number of hours spent. So, the other side of the equation is 15 (the starting cost) plus 4 (the rate) times x (the unknown number of hours).

So, our equation is 15 + 4x = 40.

Good luck ^^

Answer:

D

Step-by-step explanation:

Think about some easy coordinates. If you plug in x=0, the y coordinate must be 2, eliminating B.

Next, as x becomes larger and larger, the y value decreases. This means that the value inside the bracket must be less than 1. If it is greater than 1, the y value would increase as x increased.

To illustrate, 2 < 2^2 < 2^3 < 2^4

However, 0.5 > 0.5^2 > 0.5^3

You can check this in your calculator if you need to.

Hope that helped! :)

Answer:

  ∠CBE = 59°

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

  ∠BCD +∠CDE = 180°

  ∠BCD +∠CDB +∠BDE = 180°

  (21x -5) +34 +(4x+1) = 180

  25x +30 = 180

  25x = 150

  x = 6

∠CBE = ∠CDE = 34 +(4x +1) = 4x +35 = 4(6) +35

∠CBE = 59°
