Jeremy wants to buy a new computer. The saleswoman says that he can make a down payment and then pay for the computer in installments.Here's a formula that describes this scenario:

x=t-yz

x = Amount down
y = Money each month
z = Number of months
t = Total price

Rewrite the formula to solve for the amount of money Jeremy must pay each month.

Answers

Answer: $y=(t-x)/(z)$

Step-by-step explanation:

Given: A formula that describes this scenario:

$x=t-yz$

where, x = Amount down

y = Money each month

z = Number of months

t = Total price

To solve the formula for the amount of money Jeremy must pay each month i.e. y, first subtract t on both sides of the equation, we get,

$x-t=-yz\n\n\Rightarrow\ yz=t-x$

Now, divide z on both sides, we get

$y=(t-x)/(z)$

The correct answer is:

$y=(-x+t)/(z)$

Explanation:

We want to solve for the amount of money he pays each month. This is represented by y in the equation. This means we want to isolate y in the equation:

x = t - yz

We first want to subtract t from each side:

x - t = t - yz - t

x - t = -yz

Now we want to cancel the negative sign and z. We can isolate both of these at the same time; divide both sides by -z:

We can divide the numerator by the negative sign; this gives us

$(-x+t)/(z)=y$

In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle?20°
40°
60°
90°

Answers

If an angle it is obtuse it is between 90 and 180.

Angles in a quadrilateral add up to 360.

Therefore 3 obtuse angles must add up to AT LEAST 273 and if you then added the 90 it would get you to 363 which is too large so it cant be 90 :)

A two-way frequency table is shown below that displays the relationship between pizza type and pizza crust choices. We took a sample of 110 people and recorded the following results:Thin Crust Thick Crust Stuffed Crust Total
Cheese Pizza 3 9 13 25
All-Meat Pizza 5 15 25 45
Hawaiian Pizza 2 6 32 40
Total 10 30 70 110

The restaurant is about to prepare pizza for a children's birthday party. Knowing that the party planner only wants cheese pizza, what percentage (rounded to the nearest whole percent) of the order will be for stuffed-crust pizza?

Answers

  Thin Crust Thick Crust    Stuffed Crust   Total
Cheese Pizza   3   9 13 25
All-Meat Pizza 5 15   25   45
Hawaiian Pizza   2 6   32 40
Total    10 30   70 110

Cheese Pizza : 100%
Stuffed Crust: 70/110 = 0.636 x 100% = 63.6% or 64%

Square EFGH stretches vertically by a factor of 2.5 to create square E′F′G′H′. The square stretches with respect to the x-axis. If point H is located at (-2, 0), what are the coordinates of H?A.(-5, 0)
B.(-2, 0)
C.(0.5, 0)
D.(-2, 2.5)

Answers

Square EFGH stretches vertically by a factor of 2.5 to create square E′F′G′H′. The square stretches with respect to the x-axis. If point H is located at (-2, 0), the coordinates of H will be at point "D.(-2, 2.5)." Since it stretches vertically, it assumed that it stretches all parallel with the y axis.

Answer with explanation:

Pre -image= Square E F G H

Image=Square E′F′G′H′

Vertical Stretch Factor= 2.5

Coordinates of Point H= (-2,0)

If, (x,y), is the coordinate of any point, and , m is vertical stretch factor,then coordinate of Image =(x, my)

→Here, Vertical stretch, factor is 2.5,and coordinates of H=(-2,0) then Coordinates of H' will be =(-2, 0×2.5)=(-2,0)

Option B: (-2,0)

If arctan(3/5)=K Tan(k)=?

Answers

$arctan(x)=y$

this function is the inverse function of tan...

$arctan(x)=tan^(-1)(x)$

then...

$x=tan(y)$

in this case

$arctan((3)/(5))=K$

$(3)/(5)=tan(K)$

$\boxed{\boxed{tan(K)=(3)/(5)}}$

Answer:

3/5

Step-by-step explanation:

Penn stacks all of his snowballs in a square pyramid. The number of snowballs, P(n), in n layers of the square pyramid is given by P(n) = P(n-1) + n^2 Which could not be the number of snowballs Penn has? 5, 30, 25, 14

Answers

Naturally, a pyramid of zero layers doesn't need any snowballs, so P(0) = 0. Then using the given recurrence, we find

P(1) = 1

P(2) = 1 + 4 = 5

P(3) = 1 + 4 + 9 = 14

P(4) = 1 + 4 + 9 + 16 = 30

and so on; luckily, three of these are listed among the answer choices, which leaves 25 as an insufficient number of snowballs to make such a pyramid.

More generally, we would end up with

$P(n) = 1^2 + 2^2 + 3^2 + \cdots + n^2 = \displaystyle \sum_(k=1)^n k^2 = \frac{n(n+1)(2n+1)}6$
