625 I believe. If u do -5(-5) that’s 25 bc there’s four -5’s you will be left with 25(25) with is 625

The probability of picking blue is stated as 2/10 which can be reduced to 1/5
 
 multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)

200 x 1/5 = 200 / 5 = 40

Quinn can expect to pick blue 40 times

Two linear equations are given below.
gladu [14]

Answer: You can't answer this, but here are some guidelines

Step-by-step explanation:

I would love to answer this question (coming from someone who has already completed algebra keystones) but I need to know what the linear equations are before I can. If the functions are reciprocals of one another (the slope is the opposite and the fraction is switched) it is a perpendicular line which means one solution.  If the slope is the same but the intercept is different (using y=mx+b) so if b is different but m is the same they are parallel and there is no solution. If they are the same line (same equation) there is infinite solutions. If this doesn't help I would suggest finding graph paper and trying it out and seeing the intersection points.

The coleman family purchased a camper van for $38,000. the van is predicted to depreciate by about 15% each year. write an expon
forsale [732]

The exponential equation that can model the value of the camper van , in x years is y = 38000*(0.85)ˣ .

In the question ,

it is given that

the present value of the camper van (P₀) = $38000

given the depreciation rate is 15% each year (r)= -0.15

The future value y ,of the camper van can be given by the formula

y = P₀*(1 + r)ˣ

On putting the values , we get

y = 38000*( 1 - 0.15)ˣ

y = 38000*(0.85)ˣ

Therefore , The exponential equation that can model the value of the camper van , in x years is y = 38000*(0.85)ˣ .

Answer:

A = 139.5 cm^2

Step-by-step explanation:

Ok, let's break it down into pieces. First let's find the area of the main rectangle. We know that the area of a rectangle is as follows:

A = L x W

A = 9 x 12

A = 108 cm^2

Now we need to find the area of the two triangles. There are two ways to approach this. If you can visualize that you can flip the first triangle and slide it against the second, it becomes a rectangle. Then you can simply use the same formula as before with modified numbers.

L = 7 (height of the triangle

W = 4.5 (base of the triangle (half of 9))

A (both triangles) = 7 x 4.5

A (both triangles) = 31.5 cm^2

If you can't quite figure out how to visualize that, you can simply treat them as two independent right triangles. The formula for the area of a right triangle is as follows:

A = (1/2)b x h

b = 4.5

h = 7

A (first triangle) = (1/2)4.5 x 7

A (first triangle) = 15.75 cm^2

The area of the second triangle is identical

A (second triangle) = 15.75 cm^2

The area of the two triangles added together is

A (both triangles) = A (first triangle) + A (second triangle)

A (both triangles) = 31.5 cm^2

As you can see we got the same answer both ways. Now we just have to add the area of the two triangles to the area of the rectangle

A = 108 + 31.5

A = 139.5 cm^2

Perpendicular to y=4x-7; contains the point (4,3)
san4es73 [151]
Okay, so a general rule for finding perpendicular lines in the form of y = mx + b is y = (-1/m) + b.
First, let's ignore b (-7) because we're going to find that later.
A perpendicular line to y = 4x + b is y = -1/4x + b.
Alright, so now let's plug in the values. They are in the form of (x,y), so let's plug them in accordingly.

3 = -1/4(4) + b
3 = -1 + b
b = 4
y = -1/4x + 4
So a line perpendicular to y = 4x - 7 is y = -1/4x + 4.
