Trina planted 43 plants in her garden last week she planted twice as many cucumbers as zucchini and 8 more tomatoes then cucumbers what is the number of each kind of plant in her garden

Answers

Trina planted 7 zucchini(z) plants, 14 cucumber(c) plants, and 22 tomato(t) plants. This is the case because 43-8=35, you subtract 8 because of the extra tomatoes, then using zucchini as a checkpoint you have 1z 2c's and 2t's, total that's 5 equal parts. Then just divide 35 by 5 to get 7 so you know you have 7 zucchini, which means you have 14 cucumber and 22 tomatoes.

Annie is a financially responsible person who keeps a detailed record of the activities in her bank account.1. Annie is considering opening a certificate of deposit (CD) account. The CD account will earn interest. However, it does not allow her to deposit or withdraw money for 2 years.

First Bank is offering a CD account with a 1.8% interest rate each month. The interest is compounded. In other words, the interest earned each month will be based on the total account balance from the previous month. Annie has $500 to start the account.
(a) Fill in the table showing the amount of money in the CD account over 4 months. banks always round down to the nearest cent when necessary.
(b) if annie graphed the function, what would the y-intercept be? how do you know this?
(c) is the relation a function? Explain why or why not.
(d) is the relation linear? if so, state the rate of change and write the equation of the relation, where x is the number of months and y is the amount in the account. if not, explain why not.

Answers

a)
1st Month: 509
2nd Month: 518.162
3rd Month: 527.488916
4th Month: 536.984 (3 d.p.)

b)
500. The "zero"th month ie. when no interested has been compounded will only have her original deposit.

c)
Yes, you cannot have two different balances of money.

d)
Yes, compound interest can be showing like so:
Y x 1.018^X

53% of 539this is a math problem
the answer is supposed to be a whole number and you are supposed to estimate

Answers

53% of 539
= 53/100 x 539 
= .53 x 539
= 285.67

since its supposed to be a whole number we can round up to the nearest hundredth 285.67 = 286

When you have a triangle and 2 of 3 angles are given the degrees and the last one is unknown, you subtract the two given degrees from each other to get your unknown, right? Just checking :D Tell me if I'm wrong from my notes and file attached please

Answers


No, that's not right.  Sadly, the answer you entered on the
attached drawing is incorrect.  It's slightly more complicated
than that ... only slightly.

First, think about this for a second:  What if the two GIVEN angles
on the drawing had the same number of degrees ?  Then by the
method you've been using, you would subtract them from each
other, and that would give you zero.  So you would say that the
last angle is zero degrees ?  Can you see that this doesn't really
work ?

Here's how it's really done:

It all rests on a rule about triangles.  This is ALWAYS true, and
you should memorize it:

           When you add up the degrees of all three angles
           inside a triangle, the sum is ALWAYS 180 degrees.

So now, when you're given two of the angles, you know that
the unknown one must be exactly enough to bring the sum of
ALL of them up to 180 degrees.

Work it like this:

-- Take the two given angles.
-- ADD them.
-- Subtract their SUM from 180.
   Now you have the third angle.

In the drawing you attached:

-- The given angles are  39  and  102 .
-- Add them:  39 + 102 = 141
-- Subtract the sum from 180:    180 - 141 = 39 .
   The unknown angle is 39 degrees.

But that's the same as one of the given angles ! ?   :-(    ?    :-(

That's OK.  It's perfectly fine for two of the angles, or sometimes
even all three, to be the same size.  They just have to all add up
to 180 degrees, and everything is fine.

no add then subtract that ans from 180 degrees
