Hello!

As you can see, two of the triangles that we see that are made from the lengths we are given make up one face of the pyramid. We can use the triangle formula without multiplying by 1/2 to find the length of one face.

30(45)=1350

Now we multiply this by four to find all of the sides.

1350(4)=5400

We find the area of the square base

30(30)=900

Finally, we add up our lengths.

5400+900=6300

Therefore, our answer is C) 6400 yards²

I hope this helps!

Name 4 decimals whose sum is 2.35

Sever21 [200]

Answer:

The values of 4 decimals whose sum is 2.35 will be:

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

Step-by-step explanation:

Name 4 decimals whose sum is 2.35

Let us consider that

a be first decimal

b the second decimal

c be the third decimal

d be the fourth decimal

According to the condition, we have to determine

$a\:+\:b\:+\:c\:+\:d\:=\:2.35$

As we have to name 4 decimals whose sum is 2.35.

So, taking the certain values of a, b, c and d as

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

The sum of a, b, c and d will be:

$0.35+0.68+0.81+0.51=2.35$

Putting the values of a, b, c and d in the equation $a\:+\:b\:+\:c\:+\:d\:=\:2.35$ .

$a\:+\:b\:+\:c\:+\:d\:=\:2.35$

$0.35+0.68+0.81+0.51=2.35$

$2.35 = 2.35$

Therefore, the values of 4 decimals whose sum is 2.35 will be:

$a\:=\:.35$

$b=.68$

$\:c=.81$

$d=0.51$

Answer: y= -2x - 4

Step-by-step explanation:

This is a straight line, so it can be expressed by y = mx + c.

Here c is y-intercept, which means where line cuts the y-axis. We can see from the graph that the line cuts the y-axis at -4.

So, c = -4.

m is slope.

Use slope formula to find m.

m = ( -4 - 0 ) / ( 0 -(-2))

m = -4 / 2

m = -2

Now put values into this equation

y = mx + c

y = -2x - 4
