Answer:

.47

Step-by-step explanation:

First you would substitute 2 for a, since that’s the amount of almonds bought.

5.20(2)+2.75r=11.70

Then you multiply 5.20 and 2

10.4+ 2.75r=11.70

Subtract 10.4 from each side of the equation to help isolate the variable

2.75r=1.30

And last you will divide each side by 2.75 to get the variable on its own. The final answer is .4727

Rounding would get you to .47

In this diagram, BAC – EDF. If the
puteri [66]
The triangles are congruent. So.

Triangle ABC is 24 inch^2 and BC is 4 inches.
The area of a triangle is 0.5 x base x height. The will be 12 because 12 x 4 x 0.5 which equals 24.

Triangle DEF is half the size of ABC because bc is 4 and EF is 2 showing it’s half. This then means the height will be half which then mean it will be 6.

This then means we can use the equation to work it out. So. 6 x 0.5 x 2 = 6in^2

The answer is 6inches^2

A circle is defined by the equation x2 + y2 + 8x + 22y + 37 = 0. What are the coordinates for the center of the circle and the l
inn [45]
We can say that:
8x = -2ax
8 = -2a
a = -4

22y = - 2by
22 = -2b
b = -11

37 = a² + b² - r²
37 = (-4)² + (-11)² - r²
r² = 16 + 121 - 37
r² = 100
r = 10

With all this information, we can say that:
The center of the circle is: (-4 ; -11)
and the radius of the circle is r = 10

P.S:
(a - x)² + (b-y)² = r²
a² - 2ax + x² + b² -2by + y² - r² = 0
x² + y² -2ax - 2by + a² + b² - r² = 0

Ray Of Light [21]
The answer is 7x = 6(x + 15)

x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours:  7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours:    6y = half of the floor
So: 7x = 6y

</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15

</span>7x = 6y
y = x + 15

Substitute the second equation into the first one:
7x = 6(x + 15)
