Stan's bank account balance is less than -$20.00 but greater than -$21.00. What could Stan's account balance be?

How tall is the tree

bija089 [108]

Answer:

It is 19 feet tall.

Step-by-step explanation:

Tan(35) = 0pposite / adjacent

The adjacent side = 20 feet

The opposite side is unknown = x

Tan 35 = 0.7

tan(35) = x/20

x = 20 * tan(35)

x = 20 * 0.7

x = 14

But Chiss' eyes are 5 feet from the ground. The tree is another 5 feet.

tree = 14 + 5

Tree = 19 feet.

4 1/2 divided by 3/4

Anton [14]

Answer:

6

Step-by-step explanation:

First, change 4 1/2 into a fraction.

$4\frac{1}{2} \div \dfrac{3}{4} =$

$= \dfrac{4 \times 2 + 1}{2} \div \dfrac{3}{4}$

$= \dfrac{9}{2} \div \dfrac{3}{4}$

$= \dfrac{9}{2} \times \dfrac{4}{3}$

$= \dfrac{9 \times 4}{2 \times 3}$

$= \dfrac{3 \times 3 \times 2 \times 2}{2 \times 3}$

$= 3 \times 2$

$= 6$

Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P'Q'R' has v

almond37 [142]

Answer:

Part A: The scale factor is 2

Part B:

P''(-4, 0)

Q''(-3, 1)

R''(1, -2)

Part C: No

Step-by-step explanation:

Part A:

The coordinates of the triangle PQR are P(8, 0), Q(6, 2), and R(-2, -4)

The coordinates of the triangle P'Q'R' are P'(4, 0), Q'(3, 1), and R'(-1, -2)

Please find attached the plot of triangles PQR and P'Q'R'

The length of the sides are given by the following formula;

Using an online length

For PQ. the length =

For PR. the length =

For RQ. the length =

While for triangle P'Q'R', we have;

For P'Q'. the length =

For P'R'. the length =

For R'Q'. the length =

∴ PQ = 2 × P'Q'

PR = 2 × P'R'

QR = 2 × Q'R'

Therefore, the scale factor = 2

Part B

By reflecting about the y-axis we have;

Coordinates of the preimage (x, y) after reflection across the y=axis becomes (-x, y)

Therefore, the coordinates of the triangle P''Q''R'' are;

P'(4, 0) after reflection = P''(-4, 0)

Q'(3, 1) after reflection about the y-axis is Q''(-3, 1)

R'(-1, -2) after reflection about the y-axis becomes R''(1, -2)

Part C: No

Given that the triangle P''Q''R'' is congruent to triangle P'Q'R', and triangle P'Q'R' is similar to but not congruent to triangle PQR, we have that triangle P''Q''R'' is similar to but not congruent to triangle PQR.

Is 19-10 equal to20-10 is 19 take away 10 equill to 20 take away 10

Anni [7]

First lets write this out:-

?
19 - 10 = 20 - 10

Now lets solve:-

19 - 10 =9

?
9 = 20 - 10

20 - 10 = 10

9 ≠ 10

Since 9 does not equal 10:-

19 - 10 ≠ 20 - 10

Hope I helped ya!!

The table shows the balance of a money market account over time. Write a function that represents the balance y (in dollars) aft

dexar [7]

9514 1404 393

Answer:

y = 2200(1.08^t)

Step-by-step explanation:

The interest earned the first year is ...

(2376 -2200)/2200 = 0.08 = 8%

The balances the remaining years are consistent with that interest being compounded annually. An appropriate function is ...

y = 2200(1.08^t)

_____

The compound interest formula is ...

A = P(1 +r/n)^(nt) . . . . principal P earning rate r compounded n times per year for t years
