11. If The Perimeter Of The Given Triangle Is More Than 22 Cm And Less Than Or Equal To 30cm. Express

Answers

Answer 1

Answer:

5 < x ≤ 7

Step-by-step explanation:

perimeter = 2x + x + x + 2 = 4x + 2

perimeter is more than 22 so 22 is less than perimeter , then

22 < 4x + 2 ≤ 30 ( subtract 2 from each interval )

20 < 4x ≤ 28 ( divide each interval by 4 )

5 < x ≤ 7

Expression above should be further simplified for which value of X?

Answers

Answer:

D. 329

Step-by-step explanation:

119 can be expressed as the factors of 2 prime numbers: 7 and 17.

There would be no need to further simplify the expression if x does not have one of these factors.

We can check that D is the only one that has one of these factors: 7, since 329/7 = 47.

9. Tony bought x boxes of cookies to bring to a party. Each box has 28 cookies. He decides
to keep 2 boxes for himself. He brings 84 cookies to the party.
Which equation can be used to find the number of boxes Tony brought to the party?
A. 2x - 28 = 84
B. 28x - 2 = 84
C. 28x – 56 = 84
D. 56 – 28x = 84

Answers

The correct answer is C. 28x – 56 = 84

Explanation:

Writing an equation using a description or situation involves including all the factors mentioned and relating these appropriately through mathematical symbols. In the case presented, the correct equation is 56 – 28x = 84. This is because this equation includes the total of boxes Tony took to the party 84 and this has been correctly included after the symbol =. Also, the total of boxes is equal to the boxes tony bought each with 28 cookies, which can be represented as 28x (x represents the value of boxes that multiplied by 28 leads to the total of cookies) minus the cookies Tony bought (2 boxes each with 28 cookies). This makes the final equation to be 28x – 56 = 84.

Answer:

acute17

Step-by-step explanation:

1. Put the value of x in the expression and see what the angle measure is.

  m∠A = 4x +12 = 4(15) +12 = 60 +12 = 72

The angle is less than 90°, so is acute.

__

2. The measure of a right angle is 90°, so you have ...

  4x +22 = 90

  4x = 68 . . . . . subtract 22; next, divide by 4

  x = 17

Kirin is saving money to enter a craft fair with his new jewelry business. The entry fee is $150. He sells bracelets for $4 each and he has saved up $36. so far. What is the least number of bracelets he would need to sell to afford the entry fee?​

Answers

Answer:

28.5 equals ab 29 bracelets

Step-by-step explanation:

Answer:

29 bracelets

Step-by-step explanation:

The first thing you (always) need to do is highlight important details. Some things you should highlight are: The entry fee is $150, He makes $4 off of each bracelet, and that he has $36 so far. We know that 4 times 10 is 40. if we add 40+ the 36, we get 76. now we need 74 more dollars, so let's do: 74 divided by 4 = 18.5. since we can't do that, we add one more bracelet to make it 19. This makes sure we get enough money for the fee. All we have to do now is add is together. 10+19= 29 bracelets

Answers

Answer:

250 Hamburgers

302 cheeseburgers

Step-by-step explanation:

you sold X number of hamburgers

and x+52 number of cheeseburgers

total was 552

make an equation x+x+52=552

so 2x+52=552

now solve for x

x=250

to find cheeseburgers

(250)+52=302

hamburgeres =x=250

Answer:

Angle YZX = 19.7 degrees

This is the same as saying angle Z = 19.7 degrees

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

Explanation:

Since there are only three letters, and nothing else, we can refer to "angle YZX" as "angle Z" to shorten things. The middle letter is what determines the vertex of the angle.

With Z as the reference angle, side XY = 7.5 is the opposite side. It's the leg furthest from the reference angle. SIde ZY = 22.3 is the hypotenuse. The hypotenuse is always opposite the 90 degree angle.

We'll use the sine rule since it connects the opposite and hypotenuse

sin(angle) = opposite/hypotenuse

sin(Z) = XY/ZY

sin(Z) = 7.5/22.3

sin(Z) = 0.336323

Z = arcsin(0.336323)

Z = 19.653008983888

Z = 19.7

In this case, rounding to 3 sig figs means rounding to 1 decimal place (the first two digits are part of the whole number while the last digit is the decimal portion).

Make sure your calculator is in degree mode. The notation "arcsin" refers to arcsine which is the same as inverse sine. Your calculator would likely have the button [tex]\sin^{-1}[/tex] to indicate inverse sine.

Answer:

Degrees: 19.7

Radians: 0.343

Step-by-step explanation:

First, let x = angle YZX.

You can solve this using sine (which as a reminder, is opposite over hypotenuse):

sin(x) = 7.5/22.3

x = arcsin(7.5/22.3)

Now you can grab out a calculator and evaluate.

If it's in degrees: 19.7

If it's in radians: 0.343

(Remember to round to 3 significant figures like the problem said)

lim x>-1 x^2-x-2/x+1

Answers

Answer:

-3

Step-by-step explanation:

If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.

In this case, factoring the polynomial at the top would be helpful.

The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)

The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:

-1-2 = -3

Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.

I hope this helped you.
