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

Step-by-step explanation:

think it would be b

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:

Letter A. 50,000 + 100 > 75,000

pls give me a brainly's and I hope this answer can help you

Answer:

A. 50,000+100× = 75,000

Step-by-step explanation:

there you go that is the correct answer

 If Ed earns $100 from each extra deal, then $25,000 divided by $100 equals 250. Ed sold 250 computers last year. The correct equation is (A) 50,000 + 100X = 75,000. Base Salary + (Commission Fee x Computers Sold) = Total Income, where the unknown "X" is the number of computers sold by Ed.

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:

A

Step-by-step explanation:

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

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°

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:

find the length??

Step-by-step explanation:

you do understand that length means finding how long something is right?

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:

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

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

Answer:

−0.965925826289068

Step-by-step explanation:

sin 255 = −0.965925826289068

Answer:

x = 12.206555

Step-by-step explanation:

10^2 + 7^2 = 149

Sqrt(149) = 12.206555 = x

x ≈ 12.2, 12

Therefore, the value of the hypotenuse [tex]x[/tex] is [tex]12[/tex].

What is the pythagorean theorem?

The Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

Here given that,

[tex]B=7,P=10[/tex]

As we know,

[tex]H^2=B^2+P^2[/tex]

Substitute the given values in the formula is

[tex]x^2=(7)^2+(10)^2\\\\x^2=49+100\\\\x^2=149\\\\x=\sqrt{149}\\\\x=12[/tex]

Hence, the value of the [tex]x[/tex] is [tex]12[/tex].

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.
