the radius of a circle is 7 in. what is the circumference?
​

Answer:

B. 2.

Step-by-step explanation:

You can find the average by substituting the given values in the function, then  do an arithmetic average with results.

So, for X = - 1 you get f(-1) = 1

For X = 0 you get f(0) = 3

So, the average with 1 and 3 is 2. Because you sum numbers which results 4, and then divided by 2 (the amount of numbers involved in the average).

Answer:

4 1/8km

Step-by-step explanation:

if you have done 3 1/4km you can multiply the fraction by 2 so you get 3 2/8.

so now we have 2 5/8km and 3 2/8.

(its always easier to have the fractions the same denominator)

now we add the whole numbers first.

2 km + 3km = 5km.

now the fractions.

5/8 km + 2/8 km = 7/8km.

now add them both together and we get.

5 7/8 km.

take that answer away from 10.

we get 4 1/8km.

Answer:

£6,000

Step-by-step explanation:

Use the simple interest formula:

I = Prt

I = (Principal Value)*(Annual Interest Rate)*(Time in Years)

I = (120000)(0.12)(5/12)

I = 6000

Therefore, the simple interest is £6,000

Answer:

161.5 km/hr

Step-by-step explanation:

The number of people that were surveyed are 350 people

The given parameters are:

p = 78% --- the proportion of people that like listening to music in the car

Car =273 --- the number of people for the given proportion

The total number (n) of people surveyed is then calculated as:

Car = p * n

This gives

78% * n = 273

Express 78% as decimal

0.78 * n = 273

Divide both sides by 0.78

n = 350

Hence, 350 people were surveyed

Answer:

x = -2 and y = -4

Step-by-step explanation:

Given:

2x + y = -8

x - y = 2

Add the two equations:

3x + 0y = -6

3x = -6

x = -2

Sub x = -2 into the second equation

-2 - y = 2

-4 = y

Therefore, x = -2 and y = -4

[tex]\displaystyle\bf\\\bigg(\frac{1}{\sqrt y}\bigg)^{\dfrac{-1}{5}} =\bigg(\frac{1}{\sqrt y}\bigg)^{(-\b1)\times\dfrac{1}{5}} =\sqrt{y}^{\bigg(\dfrac{1}{5}\bigg)}=\sqrt[5]{\sqrt{y}}=\boxed{\bf\sqrt[10]{y}}[/tex]

Check:

volume = height x length x width

252 = 7 x 12 x 3

252 = 252

Answer:

3/10

Step-by-step explanation:

So 15/50 and 20/50 are used, so you add them together, which would be 35/50

Then you subtract 35/50 from 50/50 to find what is left, which would be 15/50

Simply that by dividing the numerator and denominator by 5, which the final answer would be 3/10

Answer:

m = 4

Step-by-step explanation:

Isolate the variable

2m = 8.     divide both sides by two to get the variable alone

m = 4

Check

2(4) + 7 = 15

8 + 7 = 15

Answer:

m=4

Step-by-step explanation:

2m+7 = 15

Subtract 7 from each side

2m+7-7=15-7

2m = 8

Divide each side by 2

2m/2 = 8/2

m= 4

Check

2(4) +7 = 15

8+7=15

Step-by-step explanation:

we can find value of x and y through Pythagoras theorem

according to it

h² = a² + b²

h = hypotenuse (i.e longest side of a right angled triangle)

a = side

b = base

in ∆ABC

AB² = AC² + BC²

(10)² = (8)² + x²

100 = 64 + x

x = 100 - 64 = 36

x² = √36 = 6

x = 6

in ∆PQR

PQ² = PR² + RQ²

y² = (4)² + (3)²

y = 16 + 9

y = 25

y² = √25 = 5

y = 5

a) angle BAC = angle QPR

b) value of x = 6 cm

Step-by-step explanation:

Let's solve your equation step-by-step.

−25(x+3)=8

Step 1: Simplify both sides of the equation.

−25(x+3)=8

(−25)(x)+(−25)(3)=8(Distribute)

−25x−75=8

Step 2: Add 75 to both sides.

−25x−75+75=8+75

−25x=83

The total volume of water in the tank after 3 mins 24.75 gallons.

The new volume of water that entered into the tank is calculated as follows;

V₁ = 0.1 L/sec x (3 x 60 s)

V₁ = 18 L

1 liter = 0.264 gallons

18 Liter = ?

= 18 x 0.264

= 4.75 gallons

V = 20 gallons + 4.75 gallons

V = 24.75 gallons
