Can someone plz help me with this one problem plz!!!

Answer:

HK=42°

Step-by-step explanation:

because the arc of HK is two time bigger than HLK measurement

HLK=1/2HK

21°=1/2HK cross production

HK=2×21°

HK=42°

Answer

8.7

All the first digits are even numbers..and the numbers behind the decimal points are odd numbers

Answer:

8.7

Step-by-step explanation:

I'm assuming you want the term between 6.5 and 10.9

The sequence is aritmetic with a

common difference of 6.5 - 1.3 = 4.3 - 2.1 = 2.2

6.5 + 2.2 = 8.7

Answer:

k = (1 , 4)

Step-by-step explanation:

here's your solution

==> k^2 - 5k + 4. [ is expression ]

==> by using middle term split

==> k^2 - 4k - k + 4

==> taking common from each

==> k(k - 4) - 1 (k - 4)

==> (k - 1) , (k - 4).

==> k - 1 = 0

==> k = 1

==> k - 4 = 0

==> k = 4

hence , k = (1 , 4)

The correct margin of error for a 68% confidence interval is option D 4 centimeters.

Let's calculate the margin of error correctly for a 68% confidence interval.

To calculate the margin of error, we need to determine the critical value associated with a 68% confidence interval. For a normal distribution, the critical value is approximately ±1 standard deviation.

Given that the standard deviation is 64 centimeters, the margin of error can be calculated as:

Margin of Error = 1 * (Standard Deviation / √Sample Size)

= 1 * (64 / √256)

= 1 * (64 / 16)

= 1 * 4

= 4

Therefore, the correct margin of error for a 68% confidence interval, based on the given information, is 4 centimeters. The correct answer is option D.

Step-by-step explanation: 8.8 x 10^ 5 = 880000

An ant can carry 0.044 pound of weight.

Important information:

Weight of an ant in standard form is:

[tex]8.8x10^{-6}=8.8\times \dfrac{1}{1000000}[/tex] pound

[tex]8.8x10^{-6}=0.0000088[/tex] pound

They can carry objects up to 5,000 times greater than their own body weight. So, the possible weight they can carry is:

[tex]0.0000088\times 5000=0.044[/tex]

Therefore, an ant can carry 0.044 pound of weight.

Answer:

(2x+3)(x-5)

Step-by-step explanation:

Given the expression 2x²-7x-15

Factorize

2x²-10x+3x-15 =0

2x(x-5)+3(x-5)

(2x+3)(x-5)

Hence the factored form of the expression is (2x+3)(x-5)

HI thts way tooo much to answer but ye

Answer:

90

Step-by-step explanation:

radius = 6/2 = 3

(3x3x3x10)/3 = 270/3 = 90

The third side is [tex]\sqrt{42}[/tex]

So Pythagorean's theorem is the following

[tex]Short^2 + Long^2 = Hypotenuse^2[/tex]

From here we can input the following information that we know

[tex]Short^2 + 4\sqrt{3}^2 = 8^2\\Short^2 + 12 = 64\\Short^2 = 64 - 12\\Short^2 = 42\\Short = \sqrt{42}\\[/tex]

P: 15  Area: 8

Step-by-step explanation:

Use the line to split the shape. For P add all the numbers and add a 4 and a 1 too. For the area, you have to multiply 2 by 2 because of the cube, then mulitply 4 by 1 because 2+2=4 and the other number is one. REMEMBER TO SHOW YOUR WORK AND DOUBLE-CHECK!

Answer:

The numbers are approximately: 4.000 and 1.000

Step-by-step explanation:

The given parameters can be expressed as:

[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]

[tex]\frac{x}{1000} - \frac{y}{1000} \approx 3[/tex]

Required

Determine the numbers

In each of the equations, multiply by 1000

[tex]1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5][/tex]

[tex]x + y \approx 5000[/tex]

[tex]1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3][/tex]

[tex]x-y \approx 3000[/tex]

So, we have:

[tex]x + y \approx 5000[/tex]

[tex]x-y \approx 3000[/tex]

Add the two equations

[tex]x + x + y - y \approx 5000 + 3000[/tex]

[tex]2x \approx 8000[/tex]

Solve for x

[tex]x \approx 8000/2[/tex]

[tex]x \approx 4000[/tex]

Substitute [tex]x \approx 4000[/tex] in [tex]x + y \approx 5000[/tex]

[tex]4000 + y \approx 5000[/tex]

[tex]y \approx 5000 - 4000[/tex]

[tex]y \approx 1000[/tex]

Using:

[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]

We have:

[tex]\frac{4000}{1000} + \frac{1000}{1000} \approx 5[/tex]

[tex]4.000 + 1.000 \approx5[/tex]

This implies that, the numbers approximates to 4.000 and 1.000, respectively.

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

well you know it's a 90°   so do you know what  Sin(90) is?   you should :D

I think this is kinda a trick question too b/c Opp here is also Hyp  

so it would like like    sin(90) = Opp / Hyp  but  that's  427/427 for this question.   seems kinda confusing  why ask it  that way.. huh  :/

sin(90) = 1
