Answer 1

Answer:

126.5

Step-by-step explanation:

first, break the figure into a triangle and a square (do I have to tell u where)

the square: 11*8=88

the triangle: 11*7=77 77/2= 38.5

88+38.5= 126.5

Answer 2

The solution is, the area of the given figure is : 126.5cm^2.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

we need to find the area of the given figure.

so, we have ,

first, break the figure into a triangle and a square

now, we get,

the square:

area= 11*8

=88

and, we have,

the triangle:

area =1/2* 11*7

=1/2*77

= 77/2

= 38.5

so, we get,

the area of the given figure is:

88+38.5= 126.5

Hence, The solution is, the area of the given figure is : 126.5cm^2.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.

4 ¹/₂ d < - 72

Simplify the inequality, then we have

4 ¹/₂ d < - 72

4.5d < - 72

d < - 72 / 4.5

d < - 16

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

Answers

Answer:

There are infinitely many solutions to the system.

{36x+21y=24312x+7y=81

Multiply the second equation by 3.

3(12x+7y36x+21y=81)=243

Subtract this new equation from the first equation.

36x+21y−(36x+21y0+0=243=243)=0 true

There are infinitely many values of x and y are possible.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

Two school groups go to a roller skating rink.

One group pays $243 for 36 admissions and 21 skate rentals.

The other group pays $81 for 12 admissions and 7 skate rentals.

Let x represent the cost of admission and let y represent the cost of a skate rental.

We have a system of equations,

36x + 21y = 243 {equation 1}

12x + 7y = 81 {equation 2}

Simplifying equation 1 we get,

36x + 21y = 243

Divide by 3,

12x + 7y = 81

That means, there are infinitely many solutions possible.

Therefore, there are infinitely many solutions possible.

Option 4: 10d + 5

Step-by-step explanation:

Given the algebraic expression, 5(2d + 1), which represents the fines per day, d, for overdue books.

In order to determine the equivalent algebraic expression of 5(2d + 1), we must distribute 5 into the terms inside the parenthesis:

5(2d + 1)

z = -3/2

Step-by-step explanation:

Our goal here is to solve -1/3 (4+z)=-5/6 for z.

Begin by multiplying both sides by 6, to eliminate the fractions:

-2(4 + z) = -5

Isolate (4 + z) by dividing both sides by -2: 4 + z = 5/2

Finally, determine z by subtracting 4 from both sides: z = 5/2 - 8/2 = -3/2

z = -3/2

Answers

Answer:

length= 35 feet and width= 10 feet

Step-by-step explanation:

You are given the perimeter of the rectangular deck is

90 feet.

2 x length + 2 x width = 90 You are also given that the deck's length is 5 feet less than 4 times it's width. That is length = 4 x width - 5

Those two equations are your system of linear equations. The second equation can be plugged into the first equation. This gives us an equation entirely in terms of width.

2x (4 x width - 5) + 2 x width =90

Distribute the 2 though

8 x width - 10 + 2 x width = 90

Combine like terms with width.

10 x width - 10 = 90

Add 10 to both sides.

10 x width = 100

Divide both sides by 10 width = 100

Now you can plug width into your original equation for length above. Recall: length = 4 x width - 5

Length = 4 x 10 - 5

Length = 40 - 5

Answers

9.7333333333333333334

the answer is 9.73
explanation:
4+5 is 9 so leave that aside for now

since both 2/5 and 2/6 have a different denomination you have to find the common denomination. the common denomination is 30 because it’s the LCM for both 5 and 6.

Since you multiplied the 5 by 6 you now have to multiply your numerator by 6 which will give you 12/30 and do the same with the 2/6 but instead multiply it by 5 which is 10/30 and then add them together 22/30 after you can simplify them to 11/15 by dividing the numeration and denominator by 2

After that you can convert the fraction into a decimal which would be 0.7333 but since you can round it off and make a shorter answer you have 0.73

Lastly,Don’t forget to add your 9 that we had in the begging which is not 9.73 :)
