Answer:

The answer is 450

Step-by-step explanation:

I got this equation:

x- the speed in which the turtle walks

5x+5(x+10)=4.5x+150+x*(150)/(x+10)

I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.

By solving a system of equations, we will see that the distance is 383m

Let's define the speeds of the animals as:

We know that if they leave their houses at the same time, they meet after 5 hours, so we have:

(St + Sh)*5h = D

where D is the distance we want to find.

We also know that:

St = Sh - 10m/h

And if the turtle leaves 4.5 hours earlier, they meet at 150m from the woods.

This is written as:

St*9.5h + Sh*5h = D - 150m

So we need to solve a system of equations:

St*9.5h + Sh* = D - 150m

St = Sh - 10m/h

(St + Sh)*5h = D

Replacing the second equation into the other two we get:

(Sh - 10m/h + Sh)*5h = D

(Sh - 10m/h)*9.5h + Sh*T = D - 150m

Now we can find Sh on the second one.

Sh*14.5h = D - 150m + 95m

Sh = (D + 150m + 95m)/14.5h = D/14.5h + 16.9 m/h

Replacing that on the other equation we get:

(2*(16.9m/h + D/14.5h) - 10m/h )*5h = D

118.96m + D*(10/14.5) = D

118.96m = D*(1 - 10/14.5)

D = 118.96m/(1 - 10/14.5)  = 383m

The distance is 383m

Answer:

the answer is real, irrational

Area of rectangle = l × b = 16 × 8 = 128cm²

Area of 1 triangle = ½ × b × h = ½ × 2 × 2 = 2cm²

Area of 4 triangle = 2cm² × 4 = 8cm²

Area of shaded region

= Area of rectangle - Area of 4 triangle

= 128cm² - 8cm²

= 120cm²

Answer:

Solution given:

For rectangle

length[l]=16cm

breadth [b]b=8cm

For triangle

base[b]=2cm

height[h]=2cm

Now

area of rectangle=l×b =16*8=128cm²

area of 1 triangle=½(b*h)=½(2*2)=2cm²

area of 4 triangle=4*2=8cm²

Now

Area of shaded region=128cm²-8cm²=120cm²

is a required answer.

Given:

A bag containing the numbers 2,4,6,8,10,12.

To find:

The probability of selecting two numbers less than 10.

Solution:

We have,

Total numbers = 6

Numbers less than 10 are 2,4,6,8.

Numbers less than 10 = 4

Probability of getting a number less than 10 is:

[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]

[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]

[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]

We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.

Probability of selecting two numbers less than 10 is:

[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]

[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]

[tex]\text{Required probability}=\dfrac{4}{9}[/tex]

Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].

Answer:

First, we can find the least common denominator for 8 and 3 which is 24.

5/8 = 15/24

1/3 = 8/24  

Then we can divide 15/24 by 8/24 which is 2 1/4.

If we then do 16 divided by 2 1/4 we get 7 1/9

To find:

The measure of QS.

Solution:

In triangle QRU and QST,

[tex]\angle RQU\cong \angle SQT[/tex]              [Common angle]

[tex]\angle QRU\cong \angle QST[/tex]              [Corresponding angle]

[tex]\triangle RQU\sim \triangle SQT[/tex]              [AA property of similarity]

The corresponding sides of similar triangles are proportional.

Answer:

y = 4x - 7 (Answer C)

Step-by-step explanation:

First find the slope of this line.  Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.  

Thus, the slope, m, is

m = rise / run = 4/1, or m = 4.

Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:

y - k = m(x - h) becomes y - 1 = 4(x - 2)

Solving for y, we get:  y = 4x - 8 + 1, or y = 4x - 7 (Answer C)

Answer:

La razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Step-by-step explanation:

En el club de teatro asistieron 15 alumnos a clases. En total, son 21 alumnos. Entonces la cantidad de alumnos ausentes se calcula como la diferencia entre la cantidad total de alumnos y la cantidad de asistentes, esto es:

21 alumnos - 15 alumnos= 6 alumnos

La cantidad de alumnos ausentes es 6.

La razón es la comparación de dos cantidades y se mide como el cociente entre dos números o cantidades comparables entre sí, que se expresa como una fracción. Es decir, la razón entre 2 números a y b es el cociente [tex]\frac{a}{b}[/tex].

Entonces, la razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Answer: x > 3

Step-by-step explanation:

In order to find x, we must isolate it first.

Add one to both sides. It's now 4x < 12.

Now we divide both sides by 4, remember that every time we divide or multiply we must flip the inequality symbol.

Answer:

The formula to find the perimeter of the quadrilateral

= sum of the length of all the four sides.

Step-by-step explanation:

f(x) = 2^x (this is exponential function)

f(x) = 8

the equation is :

2^x = 8

2^x = 2³

cross out 2

so, we get : x= 3

The conversion is given below.

x is 3.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = [tex]2^x[/tex]

f(x) = strength and x is the length.

Now,

Strength = 8

So,

8 = [tex]2^x[/tex]

Taking logs on both sides.

log 8 = x log 2

x = log 8 / log 2

x = log (8/2)

x = log 4

x = log [tex]2^2[/tex]

x = 2 log 2

or

2 x 2 x 2 = 2³ = 8

So,

8 = 2³

x = 3

Thus,

x = 3.

Step-by-step explanation:

Answer:

1.58 cm

Step-by-step explanation:

Area of a square = length ²

Area of the square = 15/6 cm²

Area of a square = length ²

15/6 = length²

Find the square root of both sides

√15/6 = √length²

√2.5 = length

1.58 cm = length

Alternatively,

√15/6 = √length²

√15/√6 = length

3.87 / 2.45 = length

1.58 cm = length

Therefore, side length of the square = 1.58 cm

Answer:

7.2

Step-by-step explanation:

6^2+4^2=c^2

36+16=c^2

52=c^2

x=7.2

Let the three consecutive integers be x, x+1 and x+2.

According to the question, x+x+1+x+2=51

=>3x+3=51

=>3x+3-3=51-3

=>3x=48

=>x=16

Hence, first integer = 16,

second integer = 16 + 1 = 17 and

third integer = 16 + 2 = 18.

Answer:

A u B = {1,3,5,7,9,11,13,15,17,19,23}

A n B = {5,7,11,13}

Step-by-step explanation:

The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23

A = {5, 7,11, 13, 17, 19,23}

B are odd numbers less than 16

B = {1, 3 , 5,7,9,11,13,15}

The union of both is the list of all values present in both sets without repeating;

A u B = {1, 3, 5,7,9,11,13,15,17,19,23}

A n B is the set that contains values that are present in both sets

A n B = {5,7,11 , 13}
