Step-by-step explanation:
Answer: ∠DOB: 48°
Step-by-step explanation:
1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°
2. now we can solve for the missing variable, n.
108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°
3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°
hope this heped! ♡
Answer:
Whenever finding a rule, figure out what x+1 relates to in terms of y (aka the slope). Also, figure out the y-intercept (0,<em>y</em>)
<u>Example:</u>
x+1 = y+2.
Slope: 2 ÷ 1 = 2.
The y-intercept is (0,9)
This would make the rule y=2x+9
I am pretty sure the answer is A= 44. You have to find the area of all four different triangles (A= 1/2b•h) then add the sum of them
Cookies = 24
drinks = 8
Apply ratios
Cookies / drinks = 24/8 = 3
drinks /cookies = 8/24 = 1/3
5.
There are 3 times as many cookies as drinks
There are 1/3 times as many drinks as cookies
6.
drinks = 8
pizzas = 2
Drinks/pizzas = 8/2 = 4
Pizzas / drinks = 2/8 = 1/4
There are 4 times as many drinks as pizzas.
There are 1/4 times as many pizzas as drinks.
7.
Cookies = 24
pizzas = 2
Cookies /pizzas = 24/2 = 12
Pizzas / cookies = 2/24 = 1/12
There are 12 times as many cookies as pizzas.
There are 1/12 times as many pizzas as cookies.
