Answer:

when the verbi is taking place, answer 1

Step-by-step explanation:

this is something you will just have to memorize, but the next two answers are both relating to the person, or who and how many are talking, the last option is describing an adverb, or a word that describes a verb. remember that a verb is the action, it has nothing to do with who did it or how it was done, those are described elsewhere

Answer:

scalene acute triangle

Step-by-step explanation:

By looking at the side lengths, we can see that all of them are different, meaning the triangle is scalene. Next, we can notice that all of the angles are less than 90 degrees, meaning the triangle is acute. Putting this together, we get the triangle is a scalene acute triangle.

Answer:

P = A (1 + i)^n      where P is the payment, A the original amount and i the  interest rate for the payment period.

Assuming .195 is the annual interest rate then

i = .195 / 2 = .0975  the rate that will be compounded every 6 mos.

P = 3500 * (1 + .0975)^4 = $5078

Answer and Step-by-step explanation:

First, distribute the 2 to the 4x and 4.

[tex]\frac{8x + 8}{3}[/tex]

This can be the final answer, or you can have it as [tex]\frac{8x}{3} +\frac{8}{3}[/tex].

I'm not sure about the X =5, but I think it is saying that x is equal to 5, so we will plug 5 in to the equation.

[tex]\frac{8(5)}{3} + \frac{8}{3} \\\\\\ \frac{40}{3} + \frac{8}{3} \\\\\\ \frac{48}{3} = 16[/tex]

When x is equal to 5, 16 is the answer.

Answer:

D 91

Step-by-step explanation:

Add 3 +2 =68 +23=91

Sum of any angle in atringle is 180 (rule)

Then 180-91 =89 (the missing angle in the traingle)

Since the sum of any straight angle is 180 (Therom)

180 - 89 =91

Or

The some of 2 interior angle in a triangle equal to the opposite exterior angle (Therom)

So 68 +23 = 91

Answer:

25%

Step-by-step explanation:

Discount is given by x(1-r) = y, where x is the original price and r is the percentage (made into a decimal) that was discounted, while y is the price after the discount.

So, plugging the numbers given in, we have 950(1-r) = 712.50, as we don't know r. This is hard to find, so we replace (1-r) with m (just a random letter).

Therefore, we have 950m = 712.50. To find m, we divide 712.50 by 950, getting m = 0.75.

That is not our answer. Earlier, we subsituted (1-r) for m. Now, we subsitutite it back. m = 0.75 so 1-r = 0.75. Therefore, we get that r, the discount rate, is equal to 0.25, or 25%.

Answer:

1.25 hours or 1 hour and 15 minutes

Step-by-step explanation:

12:45 - 12:30 = :15

15 minutes equates to 1/5 of the rides

So, we multiply 15 by 5 to find the total time taken to ride all the rides.

15 x 5 = 75

75/60 = 1.25

It would take him 1.25 hours to ride all the rides at the carnival or 1 hour and 15 minutes.

It's the most logical of them all, it can't be A, it wouldn't make sense if it's C, and for D it says 6 if -5<x<-1 and it has the little line on 6 for y, it sounds a little complicated but that's my logic

Answer: [tex]\$47,471[/tex]

Step-by-step explanation:

Given

Julien's parents want $64,000 at the end of 3 years

The rate of interest is 10% annually

Suppose they invested P amount initially

So, compound interest, compounded monthly is

[tex]\Rightarrow A=P\left( 1+\frac{r}{n}\right)^{nt}\quad [\text{n=Numner of compounding periods}]\\\\\text{Insert the values}\\\Rightarrow 64,000=P\left( 1+\frac{0.10}{12}\right)^{12\times 3}\\\\\Rightarrow 64,000=P\left( 1+\frac{10}{12}\right)^{36}\\\\\Rightarrow P=\dfrac{64000}{1.3481}\\\\\Rightarrow P=\$\ 47,471.37\approx \$ 47,471[/tex]

Answer:

x=20 degrees

Step-by-step explanation:

So, lets recall some things.

First off, opposite angles are the same.

So this would make x equal 20.

But lets test this.

When you look at a X, or any other sort of two lines that cross each other, can you ever think of a time when one side is not the same as the other? No.

This is because when you change one angle, since the lines are crossed together, it will change the opposite angle. This change will always be constant as long as the two lines connect at the same point

So if you changed a 10 degree angle of two lines, so that it was 30, this would change for the other line.

I attached a image below.

I hope this explains this to you and helps! :D

==================================================================

Respuesta:

x = 20 grados

Explicación paso a paso:

Entonces, recordemos algunas cosas.

En primer lugar, los ángulos opuestos son iguales.

Entonces esto haría que x sea igual a 20.

Pero probemos esto.

Cuando miras una X, o cualquier otro tipo de dos líneas que se cruzan, ¿puedes pensar alguna vez en un momento en el que un lado no sea igual que el otro? No.

Esto se debe a que cuando cambia un ángulo, dado que las líneas se cruzan, cambiará el ángulo opuesto. Este cambio siempre será constante siempre que las dos líneas se conecten en el mismo punto

Entonces, si cambia un ángulo de 10 grados de dos líneas, de modo que sea 30, esto cambiaría para la otra línea.

Answer: The product of 5 and a number

Step-by-step explanation:

The expression 5n represents the product of 5 and a number. For example, let the number be 8. Therefore, the value of the expression will be:

= 5n

= 5 × 8

= 40

The sum of 5 and a number will be:

= 5 + n

The difference of 5 and a number will be:

= 5 - n

Answer:

110.25π sq cm

Step-by-step explanation:

so r = 21/2= 10.5 cm

area of circle = πr^2

=π (10.5)^2

=110.25 sq cm

Answer:

a=10.8; c=4.3

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees.

Two of the angles are given as 40 deg and 120 deg.

Subtract the measures of both from the sum to get the last angle:

180-40-120=20; ∠C=20°

Using Law of Sines: [tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]

[tex]\frac{a}{sin120}=\frac{8}{sin40}; a=\frac{8*sin120}{sin40}; a=10.77837084[/tex]

[tex]\frac{c}{sin20}=\frac{8}{sin40}; a=\frac{8*sin20}{sin40}; c=4.25671109[/tex]

Step-by-step explanation:

Since it says round to the nearest tenth of a foot, I might be wrong. But anyways I hope this helps!

The height of the building that has a 34 foot ladder rested on it with a distance of 25 feet is 23.0 feet.

The situation forms a right angle triangle.

A right angle triangle has one of its angles as 90 degrees. The isdes of the triangle can be found using pythagoras theorem.

Therefore, the length of the ladder is the hypotenuse of the triangle. The distance form the bottom of the ladder to the bottom of the building is the adjacent side.

The height of the building is the opposite side of the triangle. Therefore,

c² = a² + b²

34² - 25² = b²

b = √1156 - 625

b = √531

b = 23.0434372436

b = 23.0

The height of the building is 23.0 feet.
