Gwar [14]3 years ago

Answer:

A.  You also need to know that CA is congruent to LJ to prove the triangles are congruent by the SAS postulate.

B. You need to know that CB is congruent to LK to prove the triangles are congruent by the HL theorem.

Step-by-step explanation:

A. You only have one side and one angle in each triangle that are congruent. To prove the triangles are congruent by the Side Angle Side postulate, you need the other side (or other leg) next to the angle to be congruent as well (in both triangles).

B. The hypotenuse leg theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are congruent triangles. To prove this, you need to know that the hypotenuse in both triangles are congruent to one another.

If Jenny has 43 apples, and gives 12 to John. How many apples does Jenny have left ?
jonny [76]

Answer:

Well, if Jenny starts out with 43 apples but then gives 12 to John that would leave Jenny with 31 apples.

Step-by-step explanation:

43 - 12 = 31

(40 - 10) + (3 - 2)

40 - 10 = 30

3 - 2 = 1

30 + 1 = 31

Here is your answer, have a nice day!

Determine the base of a parallelogram with height 6 5/8 and area 26 1/2
jek_recluse [69]

The area of a parallelogram is found using the equation:

a = b \times h

where a is the area, b is the base, and h is the height. Substitute the known values into the equation.

26 \frac{1}{2}  = b \times 6 \frac{5}{8}

Solve for b.

26.5 \div 6.625 = b

b = 4

The base of the parallelogram is equal to 4.

I don't know if this is the right answer though lol

Annie needs $30 to buy a coat she has saved $12 and plans to work as a baby siter to earn $6 per hour which inequality shows the
tekilochka [14]

Answer:

The answer would be B. 12 + 6n is greater than or equal to 30, so n is less than or equal to 3.

explanation:

I'm bad with explaining things, but I'll try my best to explain why this is the right answer.

12 + 6n ≥ 30, so n ≤ 3

let's start with the 12 at the beginning of the inequality, Annie already has $12, so the 12 in the inequality shows the amount of money she already has being added to the $6 per hour of babysitting she needs to do (n).

Now for the + 6n, the plus is there to show that the $12 Annie already has is being added to the 6n. The 6n then represents the $6 Annie makes each hour and the n represents how many hours she needs to babysit in order to get $30. The 6 is being multiplied by the amount of hours she needs to babysit to show how much money Annie would make. Then you add on the $12 she already has.

Annie then needs at least $30, but if she makes more than $30 then she will simply have more money than needed, therefore you use the greater than or equal to sign to show that she can have more money than just $30 after working.

I hope this helps, and sorry if my explanation is hard to understand lol.
