For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.

Therefore, we have the following equations:

4t + 20 = 90\\7f + 6 = 90

From these equations, we can clear the values of the unknowns.

For equation 1 we have:

4t + 20 = 90\\4t = 90 - 20\\4t = 70

t = \frac{70}{4}\\t = 17.5

For equation 2 we have:

7f + 6 = 90\\7f = 90 - 6\\7f = 84

f = \frac{84}{7}\\f = 12

Answer:

The values of t and f are given by:

t = 17.5\\f = 12

As all humans know that the every angle of a square measures 90 degrees

so that
4t+20 = 90
4t=90-20=70
t=4.5


and
7f+6=90
7f=90-6=84
f=12


hope you got the idea

The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at
satela [25.4K]
The total cost is the dependant variable and the number of tickets along with flat out price is the independent variable.

The equation would be y = 1.25x + ?

You would insert 25 for x which equals 31.25 and insert 43.75 for y.

43.75 = 31.25 + ? Then subtract 31.25 from both sides of the equation and you would get....

12.5 = ?

That is your flat rate to get in to the fair

Solving one-step inequalities by multiplying/dividing<br><img src="https://tex.z-dn.net/?f=14v%20%5Cleqslant%2014" id="TexFormul
liubo4ka [24]

Answer: v <= 1


Step-by-step explanation:

When you have a variable by a number, you do the opposite of multiplying, so you divide

Since there's only 14v you divide 14 from itself leaving just the variable

14 ÷ 14 = 1

You repeat this and divide on the other side

14 ÷ 14 = 1

Since you arent dividing by a negative on both sides, the arrow stays the same

v <= 1

Hope this helps!

Sally buys a handbag. there was a discount of 30%. if sally paid, $17.50, what was the original price?
andrew11 [14]
The original price was $25. 

First, convert the 30% to a real mathematical number. For percents, this is always done by dividing the 30% by 100%, or 30% / 100% = 0.300.

Second, find out what 30% of $25 is. This is the amount of the sale discount. This is always found by mulitplying 0.300 by the item's cost $25, like this:

0.300 x $25 = $ 7.50.

So for this sale, you'll save $ 7.50 on this item.

This means, the cost of the item to you is

<span>$25 - $ 7.50 = $17.50.</span>

Find the surface area and volume of each figure. Round each answer to the nearest hundredth.
Llana [10]

Answer: Surface area is equal to 200cm^{2}

Volume is equal to 333.33cm^{3}

Step-by-step explanation:

First, let's do surface area.

The surface area of a pyramid is equal to 1/2(perimeter of base)(lateral height) + area of the base

The perimeter of the base is 10(4) = 40; as the base is a square with a side length of 10.

The lateral height is given as 5 cm.

The area of the base is 10(10) = 100.

We can plug those numbers into the equation to get 1/2(40)(5) + 100, which comes out to be 200cm^{2}.

Now for volume.

The volume of a pyramid is equal to 1/3(area of the base)(height).

We already have the area of the base, which is 100.

The height is given as 10 cm.

Plugging those numbers into the equation, we get 1/3(100)(10), which is 1000/3 or about 333.33cm^{3}.

Hope this helps!
