The perimeter of a triangle is34 ft. One side of the triangle is 2 times the second side. The third side is 6 ft longer than the second side. Find the length of each side

Answer:

7/1

Step-by-step explanation:

A reciprocal means you flip the numerator and the denominator (the top number and the bottom number) so In this case the reciprocal for 1/7 s 7/1.

Hope I could help!

Answer:

In similar figures, the angles are congruent, even if the sides are not. Notice that one angle in each pair of figures corresponds to an angle in the other figure. They have the same shape but not the same size

A

Step-by-step explanation:

Answer:

x = 1.73

y = 2

Step-by-step explanation:

tan 30 = 1/x

0.57735 = 1/x

x = 1.73

sin 30 = 1/y

0.5 = 1/y

y = 2

Answer:

16

Step-by-step explanation:

10÷5/8=16

Answer:

16

Step-by-step explanation:

To solve problems where a fraction is being divided, we use a reciprocal of the fraction, which means that you flip the fraction upside down and multiply by the other number. So for this problem, the opposite of 5/8 is 8/5, so we need to multiply that by 10.

10*8/5

80/5

16

Answer:

Getting an odd number would be 8/15 and the multiple of six would be 2/15

Answer:

Step-by-step explanation:

Do u see any similarities between the numbers? Both 12 and -4 have a variable(N). 8 and -7 dont have a variable, so u have to calculate them individually.

One thing to remember is just because there is a minus sign(-) or a plus sign(+) does not mean its addition or subtraction. its the value of the number. the sign to the left of the number is its value. so left of 12 is plus(+), so its a positive. left of 4 is a minus sign(-) so its a negative 4. lastly, left of 7 is minus sign(-), which means its negative 7. now u add.

lets add the variables first:

12n + (-4n) = 8n

add the regular numbers:

8 + (-7) = 1

so its 8n + 1

Answer:

Y=x*(6 feet/ 1 fathom)

Step-by-step explanation:

Answer:

value of x

(8x+7)°=(9x-4)°

vertically opposite angles are equal

8x°-9x°=-4°-7°

-x°=-11°

divide both sides by -1° don't counsel negative

x=11

value of Y

5y°=(7y-34)°

vertically opposite angles are equal

5y°-7y°=34°

-2y°=34°

divide both sides by-2° don't counsel negative

y=17

Answer:

it's 800 ft

Step-by-step explanation:

because again when you want to find the area of anything you mulipuly so

10 x 20= 200 then you get the 200 and times it by 4 so 200 x 4 = 800

Answer: 5/12

Step-by-step explanation:

Answer:

5/12

Step-by-step explanation:

We are going to change both number so they have the same denominators.

1/4x3/3= 3/12

2/3x4/4=8/12

Once we changed the number we are going to subtract the numbers.

8/12-3/12=5/12

We can't simplify 5/12 so the answer is 5/12.  

Answer:

44 + 45 = 99° divided by 2 = 49.5 (you can round to 49)

Answer:

x= 27

Step-by-step explanation:

Answer:

Step-by-step explanation:

Common ratio r = a₂/a₁ = -9/27 = -⅓

b(1) = 27

b(n) = b(1)rⁿ⁻¹ = 27(-⅓)ⁿ⁻¹

Answer:

4

Step-by-step explanation:

To find the number you have to reverse the equation

Let us call the number "x"

x + 9 = 13

So to find x we flip the equation

13 - 9 = x

Solve it

4 = x

So the missing number is 4

Answer:

The alternate hypothesis is:

[tex]H_{a} < 16[/tex]

Step-by-step explanation:

There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.

This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]

Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis

Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:

[tex]H_{a} < 16[/tex]

Is there supposed to be a picture?

Step-by-step explanation:

Answer:

x = - 6, x = 6

Step-by-step explanation:

[tex] \frac{9}{x} = \frac{x}{4} \\ \\ x \times x = 9 \times 4 \\ \\ {x}^{2} = 36 \\ \\ x = \pm\sqrt{36} \\ \\ x = \pm 6 \\ \\ x = - 6, \: \: x = 6[/tex]

Answer: Both are the same. Don't just copy this, actually try to understand it.⬇️

remember rise/over = y/x

Function 1 is rising 3 for every 2 to the right. that means 3/2 or x y

Answer:

[tex]z = -0.8[/tex]

Step-by-step explanation:

Given

[tex]n = 32[/tex] --- samples

[tex]\mu = 18g[/tex] --- mean

[tex]\sigma =5g[/tex] --- standard deviation

[tex]x = 14g[/tex] --- observed value

Required

Find the standardized score

This is calculated as:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So:

[tex]z = \frac{14g -18g}{5g}[/tex]

[tex]z = \frac{-4g}{5g}[/tex]

[tex]z = \frac{-4}{5}[/tex]

[tex]z = -0.8[/tex]

The standardized score is -0.8

Step-by-step explanation:

A straight line adds up to 180°

m+3m=180°

4m=180°

m=45°

3m=45°

angle CBD=3(45)

=135°
