HELP ME PLEASE! QUESTION IS IN LINK

Mathematics
1 answer:
xenn [34]2 years ago
5 0

Answer:

Step-by-step explanation:

We know the bottom of the triangle is 5 cm and the top of the rectangle is 5 cm, but we need to find the sides.

The height of the triangle is 8 cm, we know this as we do 18 - 10 = 8 because we subtract the rectangle from the whole figure which leaves us the triangle.

We split the triangle into 2 parts. The bottom part is now each 2.5 cm.

Then we use the Pythagorean theorem.

Check my work on the picture for how I do it for which it leads to the sided of the triangle.

Now adding the sides of the whole perimeter we just focus on the outer regions.

Two parts from the triangle which both add up to 15.20 cm and the rectangle is 25 cm, you ignore the segment inside the figure.

25 + 15.20 = 37.20 cm.

What is the equation of the line that passes through the point 7,-3 and has a slope of -5
Oksana_A [137]
So i’m not sure about this but you would do the y=mx+b form and then since slope = m it would be y=-5x+b and then you would plug 7 and -3 for y and x and then you would get 7=-5-3=b and then solve for b

RULE OF FOUR: Multiple Representations of Math
nevsk [136]

Answer:

Graph ⇒ see the attached figure

Create a table ⇒ see the attached figure

Expression/Equation ⇒ y = 8x

What is the slope? ⇒ 8

What is the y-intercept? ⇒ zero

Step-by-step explanation:

Given: Meat costs $8.00 per pound at a store.

Let the number of pounds = x, and the total cost = y

So, the equation which represents the given situation is ⇒ y = mx

Where m is the slope.

If x = 1 pound , the meat costs = y = $8

So, y = 8x

The table can created by let values for x and find the values of y.

The attached table represents the table and the graph of y = 8x

The slope = 8

y-intercept is the value of y when x = 0

so, the y-intercept = 0

I need help I don't really understand this

The perimeters of both are equal.
The side of the square is 12.
Therefore, its area equals to : 12² = 144

The rectangle base is 19.
Because it has the same perimeter as the square's, so rectangle perimeter is : 19 + 19 + side + side = 12 + 12 + 12 + 12
= 38 + 2side = 48
= 2side = 48 - 38
= side of rectangle = 5
Therefore, its area is 19 x 5 = 95

If you subtract it from the area of the square, you will get : 144 - 95 = 49.
So the answer is : the area of the square is 49 units largee than the area of the square (C)

The gym is filled with 215 students & adults. Student tickets are $.50 and adults are $2.00. If $250.00 was collected, how m
BARSIC [14]
In order to determine the correct answer, it would be helpful to set up equations. We do as follows:

Let x = students
      y = adults

x + y = 215
.50x + 2y = 250

SOlving simultaneously, we have:

x = 120 students 
y = 95 adults

Hope this answers the question. Have a nice day.
