the surface area of the rectangular prism is given by formula S=2 (ab+bh+ah) find the value of h when a = 10, b=6 and s=440

Answers

Answer:

10

Step-by-step explanation:

440=2(60+6x+10x)

220=60+16x

160=16x

x=10

h=10

The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.

We have been given data as:

a = 10, b = 6 and s = 440

The surface area of the rectangular prism is given by the formula

⇒ S = 2(ab + bh + ah)

Substitute the values of a = 10, b = 6 and s = 440 in the above formula

⇒ 440 = 2(60 + 6h + 10h)

⇒ 220 = 60 + 16h

⇒ 220 - 60 = 16h

⇒ 160 = 16h

⇒ 16h = 160

⇒ h = 160/16

⇒ h = 10

Therefore, the required value of h is 10.

Genevieve is 3 years older than twice her brother's age. Genevieve is 21 years old. Write an equation to find her brother's age.​

Answers

Her brother is 9.

Because she is 3 years older than half his age, subtract 3 - 21. This gives 18. Then divide 18 / 2. This gives 9.

The equation that represents Genevieve's brother is y = 18/2.

What is the equation that represents Genevieve's brother age?

The equation that represents Genevieve's age:

21 = 3 + 2Y

Where Y represents Genevieve's brother age

In order to determine the required equation, make y the subject of the formula

21 - 3 = 2y

18 = 2y

y = 18/2

Mike went to a football game with his family. They bought 5 boxes of popcorn and 3 programs, and spent $41. Sean's family went to the same game, bought 3 boxes of popcorn and 2 programs, and spent $26. How much does each program cost at the game?

Answers

Answer:

$7

Step-by-step explanation:

Let the price of a box of popcorn = b and the price of a program = p

we can make 2 equations:

5b+3p = 41 and 3b+2p=26

We can use the subtraction method be able to eliminate one of the variables and isolate the other one - to do it I will equalize the 'b' in both equations by multiplying by 5 and 3 respectively

5(3b+2p=26)

-3(5b+3p = 41)

15b+10p=130

-(15b+9p=123)

p=7 (therefore the answer is 7$)

Side YQ and side XP are altitudes to the congruent sides of isosceles triangle WXY. Keisha is going to prove side YQ ≅ side XP by showing they are congruent parts of the congruent triangles QXY and PYX.

Answers

By the triangle congruence we can use the SSA method to prove the base angles are congruent.

What do you mean by congruent triangles?

If two or more triangles are congruent, it depends on how big their sides and angles are. The three sides and three angles of a triangle determine its size and shape, accordingly. Two triangles are said to be congruent if the pairings of respective sides and corresponding angles are equal.

These are exactly the same size and shape. There are several different congruence conditions that triangles might meet.

In the figure given,

It is necessary to demonstrate the congruence of the triangles PYX and QXY.

Both triangles have the same XY base.

PX must equal QY because the lines PX and QY are perpendicular on congruent sides.

Angles PYX and QXY are equal since the axiom "Angles opposed to equal sides are equal" states that they are.

As a result, it can be shown that the two triangles PYX and QXY have two sides and an equal angle.

As a result, using SSA criteria, the two triangles will be congruent.

Hence, option C is the best one.
