Answer:

16

Step-by-step explanation:

To be able to find the number of thistles that are in the vacant lot now using the information provided, you have to calculate the 75% of 64 and then, subtract that number from 64:

64*0.75=48

64-48=16

According to this, the answer is that there are 16 thistles in the vacant lot now.

Answer:

8 Apples

Step-by-step explanation:

You have ten dollars, and a fee of 1.25 per apple to buy,

to find the total number of apples oliva can buy, you divide the total allowance by the cost per apple

in this case,

10.00/1.25

and you get a solution of 8 Apples.

Answer:

6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

Answer:

=13x-5

Step-by-step explanation:

Answer:

13x-5

Step-by-step explanation:

You would use distributive property to get 15x-9 and then the -2x+4.

Distributive property works for the numbers in the parenthesis and you multiply the 5x and the -3 by 3.

Then, you would do your basic math to get 13x-5

Given :

A bucket is filled with 1 3/4 gallons of water.

The bucket has a small hole and 1/4 gallon leaks out every hour.

To Find :

How many hours will it take for the bucket to be completely empty.

Solution :

We know , mixed fraction of form a p/q is given by :

[tex]a\ p/q = \dfrac{(a\times q)+p}{q}[/tex]

So, 1 3/4 = 7/4 .

Let, after t hours bucket is empty.

[tex]\dfrac{7}{4}-\dfrac{1}{4}t = 0\\\\t = 7\ hour[/tex]

Therefore, it takes 7 hours for the bucket to be completely empty.

Hence, this is the required solution.

Answer:

Angle FNT = 120 Degrees because the angles labeled 7a+50 and 14a-20 are the same because the lines are parralel so you can set them equal to eachother 7a+50=14a-20 and find that a=10 After this you plug 10 into either 7a+50 and 14a-20 to get 120. You know Angle FNT is 120 degrees because it is directly across from 7a+50 which means they are the same. Then the measure of Angle KTU is 60 because Angle KTN + Angle KTU needs to add up to 180.  

Answer: the perimeter of the square is 44

Answer:

44 ft

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

Here A = 121, thus

s² = 121 ( take the square root of both sides )

s = [tex]\sqrt{121}[/tex] = 11

Perimeter = 4 × 11 = 44 ft

Answer:

i think its c

Step-by-step explanation:

The equation of a straight line is represented as: [tex]y = mx + c[/tex]

The equation of the line is: [tex](c)\ y = -x +3[/tex]

The coordinates are given as:

[tex]M = (-5,5)[/tex]

[tex]N = (5,-2)[/tex]

[tex]O = (-8,2)[/tex]

First, we calculate the slope of line MO using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{2-5}{-8--5}[/tex]

[tex]m = \frac{-3}{-3}[/tex]

[tex]m = 1[/tex]

The line that passes through N is perpendicular to MO.

This means that, the slope (m2) of the line is:

[tex]m_2 = -\frac 1m[/tex]

So, we have:

[tex]m_2 = -\frac 1{1}[/tex]

[tex]m_2 = -1[/tex]

The equation of the line is then calculated as:

[tex]y = m_2(x - x_1) + y_1[/tex]

Where:

[tex]m_2 = -1[/tex]

[tex]N = (5,-2)[/tex] --- [tex](x_1,y_1)[/tex]

So, we have:

[tex]y = -1(x -5) - 2[/tex]

[tex]y = -x +5 - 2[/tex]

[tex]y = -x +3[/tex]

Hence, the equation of the line is: [tex](c)\ y = -x +3[/tex]

Answer:

3.24 minutes

Step-by-step explanation:

Use a calculator or chart to find the z-score.

P(Z > z) = 0.60

P(Z < z) = 0.40

z = -0.253

Find the time associated with the z-score.

z = (x − μ) / σ

-0.253 = (x − 4) / 3

x = 3.24

Answer:

d = 8

Step-by-step explanation:

Given

8 + 4d = 5d ( subtract 4d from both sides )

8 = d

Answer:

d=8

Step-by-step explanation:

8+4d=5d

1. subtract 8 from both sides > 8+4d-8=5d-8

2. simplify > 4d=5d-8

3. subtract 5d from both sides > 4d-5d=5d-8-5d

4. simplify again > -d = -8

5. divide both sides by -1 > -d/-1 = -8/-1

6. simplify again > d=8

Answer:

The rate is 1.75 feet/seconds or 105 feet/minute.

Step-by-step explanation:

Given that,

Li walks at a constant rate of 7 feet in 4 seconds

To find the constant of proportionality, divide 7 feet by 4 seconds.

So,

[tex]k=\dfrac{7\ \text{feet}}{4\ \text{seconds}}\\\\k=1.75\ \text{ft/s}[/tex]

1.75 ft/s is the constant of proportionality

We know that, 1 minute = 60 seconds

k = 105 feet/minute

So, the rate is 1.75 feet/seconds or 105 feet/minute.

Since the waves are 0.15 apart and made by tapping the water surface twice each second the speed of waves in the puddle is 0.6 m/s

To answer the question, we need to know what a wave is

A wave is a disturbance in space which carries energy from one point to another

The speed of a wave v = fλ where

Since the puddles are 0.15 m are and we know that this is the distance from crest to crest.

Also, the distance from crest to crest is λ/2

So, λ/2 = 0.15

λ = 2 × 0.15 m

= 0.3 m

Also, since the tapping by the water surface is done twice each second, the frequency, f = 2 times/s = 2 Hz

Substituting the values of the variables into the equation, for speed, we have

v = fλ

v =  2 Hz × 0.3 m

v = 0.6 m/s

So, the speed of waves in the puddle is 0.6 m/s
