Can someone please help me with math.

Answer:

219.05 m²

Step-by-step explanation:

Dimension of right angle triangle : 109 m and 190 m

The right angle triangle has a height of 190 m and base length of 109 m

A corner of the base from the pyramid's top is equivalent to the hypotenus of the right angle triangle :

Let :

hypotenus = c ; base = b ; height = a

Hypotenus² = opposite² + adjacent²

c² = a² + b²

c² = 190² + 109²

c² = 36100 + 11881

c² = 47981

c = sqrt(47981)

c = 219.04565

A corner of the base from the pyramid's top is 219.05 m²

Answer:

0 is the only number without a reciprocal

Answer:

8.38

Step-by-step explanation:

The underlined number is in the hundredths place, so that means that we're going to round there. That means that you look at the number to its right and if it's lower than 5, it stays the same. However, if it's 5 or higher, you round it up. For example, if the number was 8.386, we would round it to 8.39.

Total earned for the warranties: 14 x 20 = 280

Subtract warranty amount from total:

1050-280 = 770

Divide by total TVs:

770/14 = 55

She earns $55 per tv.

Answer:

the answer of this question is

x is equal to the y to the power ➖ 1

Answer:

Below.

Step-by-step explanation:

It means that y = k/x^2 where k is some constant .

If you know the value of x when y is also known you can calculate k.

Answer:

The area of the cornfield is 1,529 yards.

Step-by-step explanation:

In this case, since the statement indicates that it is a square field, you have to use the formula to calculate the area of a square, which is:

A=a², where:

A is the area

a is the lenght of side

The statement says that one side measures 39 yards, so this would be a, and you can replace this value on the formula:

A=39²

A=1,521

According to this, the answer is that the area of the cornfield is 1,529 yards.

y=10

2×10=20-5=15

.......

Answer:

y=10

Step-by-step explanation:

15 = 2y - 5

add 5 to both sides

15 + 5 = 2y - 5 + 5

add the numbers

20 = 5y

divide

y = 10

Answer:

Answer:   x + y=100---equation 1

               y =10+ 2x-----equation 2

                 x=30, y=70

Step-by-step explanation:

Given that

x added to a number y is equal to 100 which means that

x + y=100

and also that

y is also equal to 10 more than the number x doubled which is

y =10+ 2x

we have the linear systems to solve the equations as

x + y=100---1

y =10+ 2x-----2

Solving

Putting the value of y =10+ 2x in equation 1

x +10+ 2x =100

10+3x=100

3x=100-10

x=90/3=30

x=30

y=10 +2x = 10+2x30 =70

Answer:

$3,550 dollars

Step-by-step explanation:

6.4% off savings

- a total of $2,400

The percentage is that indicating the hundredth total amount in the saving account before withdrawing such that 6.4% of that is $2400 is $37500.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Let's suppose the total amount of money before withdrawing x.

It is known that x% of y is given as, (x/100)y.

Therefore,6.4% of x is (6.4/100)x = 0.064x

The 6.4% of the x is 2400

So, 0.064x = 2400

x = 2400/0.064 = $37500

Hence "The percentage is that indicating the hundredth total amount in the saving account before withdrawing such that 6.4% of that is $2400 is $37500.".

Answer:

C) 17.1 square units

Step-by-step explanation:

Use Heron's formula to calculate the area of the triangle:

[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex]  where  [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:

[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]

Therefore:

[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]

[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]

[tex]Area = \sqrt{296.45}\\[/tex]

[tex]Area = 17.2[/tex]

Therefore, the closest answer choice is C) 17.1 square units

Answer:

perimeter = 16x+9x+8x+11

simplified perimter = 33x+11

Step-by-step explanation:

this isnt even close to 100 pts but okay

Answer:

a. 16x + 9x + 8x + 11

b. 33x + 11 (or 11(3x + 1) if this is asking for a factored expression)

Step-by-step explanation:

Looking at the directions, part a tells us to use all 4 side lengths, so the equation for part a is 16x + 9x + 8x + 11.

Now to simplify that expression.

16x + 9x + 8x + 11

Step: Combine 16x, 9x, and 8x. I'll go from left to right.

25x + 8x + 11

33x + 11

(What you see above this statement is my answer, but work is below if this is asking for a factored expression.)

11: 1, 11

33: 1, 3, 11, 33

Now divide both 33x and 11 by 11 and put the 11 outside the parentheses.

33x/11 = 3x

11/11 = 1

11(3x + 1)

3.25 times 4 equals 13. So, the plant cost needs to add up to 37. 37 divided by 2.5 is 14.8, or rounded, 15. So she can buy around 15 plants.

50 - 13/2.5 would be the inequality i think.

Please tell me if I did this the wrong way or not.

Answer:

Step-by-step explanation:

A, because more debt would build up for your credit card if you added money to a savings account since you would have to wait a whole year to get interest back. And it wouldn't be B because it simply would not be worth it to invest in stocks while in debt. Also, I just took the test and got it right!
