Answer:
a concave lens is exactly the opppostie with outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses. ... The distance from the center of the lens to the focal point is, again, the focal length of the lens.

1. Mara has $640 in her bank account. If she withdraws $30 every month, in how many months will she have $370 remaining in her account
2. Make up an equation that has no solution and explain what that means. (Hint: It has to be a real explanation, not just "it doesn't work").
Answer:
610, 580, 550, 520, 490, 460, 430, 400, 370 It takes 9 months
Step-by-step explanation:
2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.
Answer:
1. 9
2.
Step-by-step explanation:
1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:
640 - 30x = 370
Now, subtract both sides by 640 to get -270:
-30x = -270
Last, divide both side by -30:
-30x = 270
x = 9
Now, we know she withdraws $30 for 9 months.
2. 2 + 4(3 - 2) = x
This tells us that we do not know the answer until we solve it.
2 + 4(3 - 2) = x
2 + 12 - 8 = x
6 = x
in the parallelogram below z=?
Answer:
z = 20
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary so
124 + 2z + 16 = 180
2z = 40
z = 20
The value of z in the given diagram is 20°.
What is a parallelogram?A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.
As per the given data:
Two adjacent angles of a parallelogram are given in the diagram.
To find the value of z:
The sum of any two adjacent sides of a parallelogram is equal to 180°.
∴ 2z + 16° + 124° = 180°
= 2z = 180° - 140°
= 2z = 40°
z = 20°
Hence, the value of z in the given diagram is 20°.

At a hospital, 56 percent of the babies born are not girls. Of the baby girls born, 12 percent are premature. What is the probability of a premature baby girl being born at this hospital? Round to the nearest percent.
5%
7%
21%
27%
Answer:
It's the first option 5%
Step-by-step explanation:
The probability of a premature baby girl being born at this hospital is,
⇒ 5%
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Now, If the likelihood of boys being born is 56%,
Then, the complement of that is the likelihood of girls being born which is,
⇒ 100% - 56% = 44%.
Since, we are given that of the baby girls born, 12% are premature, the probability of a premature baby girl being born is:
⇒ (0.44)(0.12)
= 0.0528
⇒ 5.28%
Thus, The probability of a premature baby girl being born at this hospital is,
⇒ 5%
