Find the selling price. Original price of the telescope: $99.99 Discount: 13%

Answers

Answer 1

Answer: There is no discount stated but I'm assuming this problem is the same problem I encountered before.

Original price of the telescope is $99.99
Discount: 13%

$99.99 * 13% = 12.9987 or 13
$99.99 - 13 = $86.99 or $87

New selling price is $86.99 rounded up to the nearest unit $87.00

Answer 2

Answer: Original price = $99.99

Since there is 13% discount. New price = 100% - 13% = 87% of Original price.

= 87% of 99.99

= 0.87 * 99.99

≈ 86.99

Selling price ≈ $86.99

1.A wedding planner uses 72 ivy stems for 18 centerpieces. When she arrives at the venue, she realizes she will only need 16 centerpieces. How many ivy stems should she use so that the ratio of ivy stems to centerpieces stays the same?

Answers

Answer:

64 ivy stems.

Step-by-step explanation:

Given:

A wedding planner uses 72 ivy stems for 18 centerpieces.

When she arrives at the venue, she realizes she will only need 16 centerpieces.

Question asked:

How many ivy stems should she use so that the ratio of ivy stems to centerpieces stays the same?

Solution:

As wedding planner uses 72 ivy stems for 18 centerpieces:

Ratio of ivy stems to centerpieces = $(72)/(18)$

As she realizes that she needs only 16 centerpieces:

Let ivy stems should be used to stays the ratio same = $x$

Now, to do the ratio same:-

Old ratio = $(72)/(18)$

New ratio = $(x)/(16)$

To do the ratio same:-

$(72)/(18)=(x)/(16) \n$

By cross multiplication:

$18x=72*16\n18x=1152$

Dividing both sides by 18

$x=64$

Therefore, 64 ivy stems she should use so that the ratio of ivy stems to centerpieces stays the same.

Can somebody solve using elimination method algebra2

Answers

For the first one, you just add them and you obtain an equation in y. Solve for y, then substitute y for the solution in either of the equations, then solve for x.
In the second one, multiply the first by -2, then do the addition and something similar to the first one.

2. Another wooden plank is leaning against an outside wall of a building. The bottom of the plank is 9 ft from the wall. The length of the plank is 41 ft. Find each of the following values, and show all your work.(a) Find the value of x. Round to the nearest tenth of a degree.
(b) Find the height above the ground where the plank touches the wall. Round to the nearest foot.
Please someone help

Answers

(A) Find the value of x. Round to the nearest tenth of a degree
Given that the distance of the ground is 9ft.
Length of the plank is 41 ft

In order to get the angle formed between the ground and the foot of the plank,

cos (theta) = ground / plank
cos (theta) = 9 / 41
cos (theta) = 0.21951...
theta = cos^-1(0.21951...)
theta = 77.3 degrees

(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.

Height = square root (plank^2 - ground^2)
Height = square root (41^2 - 8^2)
Height = square root (1600)
Height = 40

(A) 77.1 Degrees
(B) 40 feet
