In integers what is -11 -6

Answer:

80 students.

Step-by-step explanation:

Since there were 50 students, and 20 students wanted the chocolate icecream, that makes a proportion of 2/5. Then, there are 200 students in this whole seventh grade, and imagine that they have the same proportion of the 50 students. So, you should do 2/5 × 200, and the answer is 80.

I hope this helps you! ;)

Answer:

39, 78, 117, 156 and 195.

Step-by-step explanation:

If the lowest number is x then we can write the numbers as:

x, 2x, 3x, 4x and 5x, so:

x + 2x + 3x +  4x +  5x = 585

15x = 585

x = 39.

So the second number is 39 * 2 = 78

So all numbers are 39, 78, 117, 156 and 195.

Step-by-step explanation:

Drone motor that has a power of 25W. 1- What will be the working voltage of said motor if it has a consumption of 1.5A? 2- What will be the resistance of said motor?

Power of drone motor is 25 W

Current flowing through the motor is 1.5 A

Power of an electrical appliance is given by :

P = VI

V = working voltage of the motor

[tex]V=\dfrac{P}{I}\\\\V=\dfrac{25}{1.5}\\\\V=16.67\ V[/tex]

Voltage of the motor is 16.67 volts

Let R is the resistance of the motor. Using Ohm's law to find it as follows :

V=IR

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{16.67}{1.5}\\\\R=11.113\ \Omega[/tex]

Hence, this is the required solution.

Given :

When price is $2 dollars he sells 2400 units .

When price is $8 dollars he sells 600 units .

To Find :

If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.

Solution :

Two points are given :

[tex](x_1,y_1)=(2,2400)[/tex]

[tex](x_2,y_2)=(8,600)[/tex]

Now , slope is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{2400-600}{2-8}\\\\m=\dfrac{-1800}{6}\\\\m=-300[/tex]

Now , the equation of line containing these two points and slope -300 is :

[tex](y-y_1)=m(x-x_1)\\\\y-600=-300(x-8)\\\\y=-300x+2400+600\\\\y=-300x+3000[/tex]

Therefore , equation for the demand curve is [tex]y = -300x +3000[/tex] .

Hence , this is the required solution .

Answer:

114, and 115

Step-by-step explanation:

114+115 = 229

Answer:

114 and 115

Step-by-step explanation:

Let's say the pages are p

so

Left page = p

Right page = p+1

p(p+1) = 229

2p+ 1 = 229 we want to know what p is so isolate the variable:

      -1       -1

2p=228 Divide:

p=114

The pages are 114 and 115

Check: 114+115 = 229

Answer:

base = 10 cm

Step-by-step explanation:

The height from the vertex is a perpendicular bisector of the isosceles Δ

This line divides the triangle into 2 right triangles with hypotenuse 13

Thus each right triangle is a 5- 12- 13 with legs 5 and 12

The height is 12 cm and the base 5 cm

Then the base of the isosceles Δ = 2 × 5 cm = 10 cm

Note Area = 0.5 × 10 × 12 = 60 cm²

Answer:

The length of the dog park is 74 feet.

Step-by-step explanation:

Given that,

Length of park = (8x+2)..(I)

Width of park = (2x-12)...(II)

Perimeter = 160 feet

We need to calculate the value of x

Using formula of perimeter of rectangular park

[tex]P=2(l+w)[/tex]

Where, l = length

w = width

Put the value into the formula

[tex]160=2(8x+2+2x-12)[/tex]

[tex]160=20x-20[/tex]

[tex]x=\dfrac{160+20}{20}[/tex]

[tex]x=9[/tex]

We need to calculate the length of the dog park

Using equation (I)

[tex]l=8x+2[/tex]

Put the value of x

[tex]l=8\times9+2[/tex]

[tex]l=74\ feet[/tex]

Hence, The length of the dog park is 74 feet.

Answer:

Step-by-step explanation:

Speed is the change in distance of a body with respect to time.

Speed = Distance/tIme

Given parameters

Distance = 8miles

TIME = 20minutes

Convert minutes to hour

since 60minutes = 1hr

20 min = x

cross multiply

20 = 60x

x = 20/60

x = 1/3

Hence 20mins = 1/3 hr

Speed = 8miles/(1/3)hr

speed = 8 miles * 3/1 hr

speed = 24 miles/hr

Hence the object's speed in miles per hour is 24miles/hour

The object's speed in miles per hour is 24 miles per hour.

Distance = 8 miles

Time = 20 minutes = 20/60 = 1/3 hour

The speed of an object is calculated as:

= Distance / Time

= 8 ÷ 1/3

= 8 × 3

= 24

In conclusion, the object's speed in miles per hour is 24 miles per hour.

Answer:

Simplifying

12r + -6s = t

Solving

12r + -6s = t

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '6s' to each side of the equation.

12r + -6s + 6s = 6s + t

Combine like terms: -6s + 6s = 0

12r + 0 = 6s + t

12r = 6s + t

Divide each side by '12'.

r = 0.5s + 0.08333333333t

Simplifying

r = 0.5s + 0.08333333333t

Answer:

6.4331 × 10 5N

Step-by-step explanation:

Given the following :

Mass (m) of car = 1200kg

Initial Velocity (u) of car = 60 mph

Final velocity = 0 ( comes to rest)

Velocity in m/s = 60 / 2.24 = 26.785 m/s

Time (t) = 0.0500

Using the relation :

Ft = m(v - u)

Where,

v = final velocity ; u = initial velocity ; t = time ; F = force

F*0.05 = 1200(26.785 - 0)

0.05F = 32142.86 - 0

F = 32142.86 / 0.05

F = 642857.14 N

F = 6.43 × 10^5 N

Answer:

[tex]y = 6[/tex]

[tex]RS = 38[/tex]

[tex]ST = 39[/tex]

[tex]RT = 77[/tex]

Step-by-step explanation:

Given:

[tex]RS = 6y +2[/tex]

[tex]ST=5y + 9[/tex]

[tex]RT= 13y - 1[/tex]

Solving (a): The value of y

From the given parameters, we understand that

[tex]RT = RS + ST[/tex]

Substitute values for RS, ST and RT

[tex]13y - 1 = 6y + 2 + 5y + 9[/tex]

Collect Like Terms

[tex]13y - 6y - 5y = 1 + 2 + 9[/tex]

[tex]2y = 12[/tex]

Divide both sides by 2

[tex]y = \frac{12}{2}[/tex]

[tex]y = 6[/tex]

Solving (b):

The value of RS

Substitute 6 for y in [tex]RS = 6y +2[/tex]

[tex]RS = 6 * 6 + 2[/tex]

[tex]RS = 36 + 2[/tex]

[tex]RS = 38[/tex]

The value of ST

Substitute 6 for y in [tex]ST=5y + 9[/tex]

[tex]ST = 5 * 6 + 9[/tex]

[tex]ST = 30 + 9[/tex]

[tex]ST = 39[/tex]

The value of ST

Substitute 6 for y in [tex]RT= 13y - 1[/tex]

[tex]RT = 13 * 6 - 1[/tex]

[tex]RT = 78 - 1[/tex]

[tex]RT = 77[/tex]

Step-by-step explanation:

Answer:

11. 9. 4.

Step-by-step explanation:

Since BD bisects ABC, angle ABD = angle CBD.

(13x - 56) = (7x + 10)

6x = 66

x = 11.

Again for the next question BD bisects ABC.

(x + 15) = (4x - 12)

3x = 27

x = 9.

For the last question,

(9x + 9) = (12x - 3)

3x = 12

x = 4.
