Answer:

x : z = 8 : 25

Step-by-step explanation:

<u>Given</u>

x : y = 2 : 5, y is 80% of z

<u>Rearranging the ratios:</u>

x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5x
y is 80% of z ⇒ y = 0.8z

<u>Comparing the values of y:</u>

2.5x = 0.8z
x/z = 0.8/2.5
x/z = 0.32
x/z = 32/100
x/z = 8/25
x : z = 8 : 25

Isabella uses the equation to find the volume of the cone below.

Rufina [12.5K]

Answer:

The correct answer option is: Isabella should have divided the product of $12\pi$ and 9 by 3 to get $V=\frac{12\pi (9)}{3}$

Step-by-step explanation:

We are given a diagram of a cone with height $9 cm$ and area of the base (circle) $12 \pi cm^ 2$ .

Isabella uses the equation $V = \frac { 1 } { 3 } ( 12 ) ^ 2 ( 9 ) \pi$ and we are to find the error that she is making in finding the volume of this cone.

The volume of a cone is given by: $\pi r^2\frac{h}{3}$ out of which $\pi r^2$ represents the area of the base (circle).

Therefore, Isabella should have divided the product of $12\pi$ and 9 by 3 to get $V=\frac{12\pi (9)}{3}$ .

The coordinates of the vertices of △RST are R(−3, −1) , S(−1, −1) , and T(−4, −5) . The coordinates of the vertices of △R′S′T′ a

ASHA 777 [7]

You are given triangle RST with vertices R(-3,-1), S(-1,-1) and T(-4,-5).

1. Apply the rotation of 90° counterclockwise about the origin that has a rule:

(x,y)→(-y,x).

Then

R(-3,-1)→R''(1,-3),
S(-1,-1)→S''(1,-1),
T(-4,-5)→T''(5,-4).

2. Second transformation is translation 1 unite up with a rule:

(x,y)→(x,y+1).

So

R''(1,-3)→R'(1,-2);
S''(1,-1)→S'(1,0);
T''(5,-4)→T'(5,-3).

As you can see these points are exactly those from the task condition.

Answer: 1st transfomation is rotation of 90° counterclockwise about the origin and 2nd transformation is translation 1 unite up

Which of the equations below could be the equation of this parabola?

BARSIC [14]

Parabolas like $y=ax^2$ have the y-axis as their symmetry axis, so options B and D are surely wrong.

Moreover, parabolas like $x=ay^2$ have the x-axis as their symmetry axis. If $a>0$ the parabola is concave rightwards, if $a$ the parabola is concave leftwards.

Since your parabola is concave leftwards, the only feasible option is $x=-2y^2$
