C. The answers is 4:10 because she has 4 tetras for every 10 goldfish. It says a ratio of tetras to goldfish so tetras would be first. Meaning your answer is 4:10. ( you could simplify to 2:5 but that is not an answer option)

Y = −(x + 4)2 − 7 vertex

ICE Princess25 [194]

Answer:

The vertex (h,k) is (-4,-7).

Step-by-step explanation:

I assume you are looking for the vertex $y=-4(x+4)^2-7$ .

The vertex form of a quadratic is $y=a(x-h)^2+k$ where the vertex is (h,k) and a tells us if the parabola is open down (if a<0) or up (if a>0). a also tells us if it is stretched or compressed.

Anyways if you compare $y=-4(x+4)^2-7$ to $y=a(x-h)^2+k$ , you should see that $a=-4,h=-4,k=-7$ .

So the vertex (h,k) is (-4,-7).

Answer:

1131.0 m³

Step-by-step explanation:

Using the formula for the volume of a cylinder, fill in the appropriate values and do the arithmetic.

V = πr²h

Since this formula needs the radius of the cylinder and you are given the diameter, you must divide the diameter by 2 to get the radius:

r = d/2 = (12 m)/2 = 6 m

Then the volume is ...

V = π(6 m)²(10 m) = 360π m³ ≈ 1131.0 m³ . . . . . rounded to tenths

HELP ME A.S.A.P. PLZZZZ

Ronch [10]

Answer:

A = 66.5 in²

Step-by-step explanation:

There are a few different equations to find the area of a rhombus. If you are given the measurements of the two diagonals, you can use the following formula:

Area (A) = $\frac{d_{1}d_{2} }{2}$

Using this formula, you can multiply the measures of the diagonals and then divide by 2:

area = $\frac{(9.5)(14)}{2} =\frac{133}{2}=66.5in^{2}$
