Find the value of each variable in the parallelogram
wlad13 [49]

Answer:

B= 90

C= 80

D= 100

Step-by-step explanation:

So let’s start with the bottom angles.

We know that the adjacent angles in a parallelogram add up to 180° so our equation would be (b-10) + (b+10)=180. So let’s simplify it b and b are both the same variables so we will get 2b and -10 + 10 is 0 so we get the following equation 2b=180.

So now we divide 180 and 2 and we get 90 as b.

So one side will be 100 because of the +10 and the other 90 because of the -10.

Now for the next side.

d+c=180

So we know that b+10 is adjacent to c so 180-100 is 80, so 80 is c.

Now for d.

b-10 is 80 so 180-80 is 100, so d is 100.

As per the problem

The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.

we have been asked to find

Which ratio shows the number of chlorine tablets needed for 42 days?

Since for each 14 days the number of tablets required is 5

So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.

So When number of days=14*3=42\\

Then the number of tablets required for 42 days is =5*3=15\\

Last question of my homework pls &lt;3​
dimaraw [331]

Answer:

J(2, 5 )

Step-by-step explanation:

Using the section formula

x_{J} = \frac{1(-2)+2(4)}{2+1} = \frac{-2+8}{3} = \frac{6}{3} = 2

y_{J} = \frac{1(1)+2(7)}{2+1} = \frac{1+14}{3} = \frac{15}{3} = 5

Thus J = (2, 5 )
