5h-2(11-h)=h-4
what’s the value of h

Answer:

47/4  or 11.75 = m

Step-by-step explanation:

-47 -2.5 = -2.5 - 1.7m - 2.3m

Combine like terms

-49.5 = -2.5 -4m

Add 2.5 to each side

-49.5 +2.5 = -2.5+2.5 -4m

-47 = -4m

Divide each side by -4

-47/-4 = -4m/-4

47/4 = m

11.75 = m

Answer: 40

Step-by-step explanation:

angle 1 and 2 are alternative interior angle which means they are equal

-------------------------------

angle 1= angle 2

2x+20=3x+10

      x=10

------------------------------

angle 1=2x+20

           =2(10)+20

           =20+20

           =40

Step-by-step explanation:

Hey there!!

Just do it in a simple way.

Use the properties of parallel lines, and find the value of x to find angke 1.

angle 1= angle 2 { alternate angles on parallel lines are equal }

[tex]2x + 20°= 3x + 10°[/tex]

or, 3x-2x = 20°-10°

x= 10°.

now,

angle 1= 2x+ 20°

=2×10°+20°

Therefore, the measure os angle 1 is 40°.

Hope it helps...

Let's find the equivalent fractions

A/B ; C/D  ⇔  A·D/B·D ; C·B/B·D

Bringing to our problem:

A/B ; C/D  ⇔  A·D/B·D ; C·B/B·D

1/3 ; 2/5  ⇔  1·5/3·5 ; 2·3/3·5  ⇔  5/15 ; 6/15

Now we can sum/add the equivalent fractions

5/15 + 6/15 = 11/15

11/15   to accomodation and food

15/15 = total

total - (accomodation and food) = other purposes

15/15 - 11/15 = 4/15

So 4/15 its the fraction for other purposes

To make AB perpendicular to CD move point B until the angle between the lines, BEC measures 90°.

Step-by-step explanation:

Plato

If you have to make AB perpendicular to CD, rotate AB clockwise, until and unless both the lines intersect at 90 degrees.

Angles : the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.   

Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function

Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Equation : A mathematical equation is used to equate two expressions.

Given is that as you move point B, the angle formed between AB and CD varies.

If you have to make AB perpendicular to CD, rotate AB clockwise, such that the point B moves in clockwise direction, until and unless both the lines intersect at 90 degrees.

Therefore, if you have to make AB perpendicular to CD, rotate AB clockwise, until and unless both the lines intersect at 90 degrees.

Answer:

120

Step-by-step explanation:

The computation of the other integer is shown below:

The Factor of 48 is 2^4 × 3

Also the greatest common divisor is 24,

This results that the second number also contains the factors 2^3 and 3 but not a fourth 2.

Now when there is a division of 240 by 48 so the number comes is 5

Now the second number factors are 2^3 and 3 that represents that it is under the factors of 48 but the factor 5 would arise from the second number

So, the other number is 120

Answer:

120

Step-by-step explanation:

If you want the aops explanation:

The prime factorization of 48 is $2^4\cdot3$. Since the greatest common factor is 24, that means the other number also has the factors $2^3$ and 3 but not a fourth 2. When we divide 240 by 48, we get 5. The factors $2^3$ and 3 of the other number are covered by the factors of 48, but the factor 5 must come from the other number. So, the other number is $2^3\cdot3\cdot5=\boxed{120}$.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 39 million

Let the value of B = 10⁷

On simplifying the value of A , we get

A = 39 million

A = 39000000

So , the value A can be written in powers of 10 as

The value of A = 39 x 10⁶

On simplifying the equation , we get

The value of A = 3.9 x 10⁷

Now , the value of A > B

And , 3.9 x 10⁷ > 10⁷

Therefore , the value of A is greater than B

Answer:

Step-by-step explanation:

Given the formula for the surface area of a cylinder as S = 2πr(r+h) where r is the radius of the cylinder's base and h is its height.

Given parameters

base radius of the cylindrical pole = 10 cm

Height of the cylindrical pole = 2 m

Since 100 cm = 1 m, then 2 m = 200 cm

Height of the cylindrical pole (in cm) = 200 cm

Required

Surface area of the pole (in cm²)

Using the formula for finding the surface area of a cylinder as shown above;

[tex]S = 2\pi r(r+h)\\\\S = 2\pi (10)(10+200)\\\\S = 2\pi 10(210)\\\\S = 2\pi * 2100\\\\S = 4200\pi cm^2[/tex]

Hence the  surface area of the pole in square centimetres is 4200πcm²

Answer:

34000cm or 340m

Step-by-step explanation:

We have to find total surface area.

Answer:

Rectangle 1 area: 53 units squared

Shape 2 area: 43.75 units squared

Step-by-step explanation:

Shape 1:

We need to find the area of the two triangles in this rectangle and subtract it from the total area of the rectangle.

Total area of the rectangle:

13 * 5 = 65

Area of triangles (they are congruent):

1/2 * 4 * 3 = 6

6 * 2 = 12

65 - 12 = 53

The area of the shaded part is 53 (I don't know what your unit of measurement is. Just say units.)

Shape 2:

First, let's find the area of the parallelogram at the top.

10 * 3 = 30

Now, let's find the area of the rest of the shape. Triangle first...

1/2 * 4 * 1.5 = 3

Now, the rectangle and the tiny triangle we can section out at the end:

7 * 1.5 = 10.5 + 1/4 (Triangle) or 0.25 = 10.75

Total area: 10.75 + 3 + 30 = 43.75

The number of 7-digit numbers are possible in a single area code is 5248600

Step-by-step explanation:

The given parameters are;

The number of digits in the area code = 7

The possible digits for X, B and C are 1 - 9 = 9 digits

The number of possible digits for A is 0 - 9 = 10 digits

Exceptions

1) B and C cannot both =

2) 555-0100 through 555-0199 are reserved for television or movies

Therefore, we have, the number of 7 digits numbers without exceptions = 10×9⁶ = 5314410 numbers

The number of the exceptions are

Exception 1) 10 × 1 × 1 × 9 × 9 × 9 × 9 = 65610 numbers

Exception 2)  555-0100 through 555-0199 = 0199 - 0100 = 200 numbers

The number of possible numbers = 5314410 - 65610 - 200 = 5248600
