Answer:

We will choose option D.

Step-by-step explanation:

In the given diagram the shown right triangle has Base = 3 units, Perpendicular = 4 and the Hypotenuse = 5 units,

Now, in option A.

The vertices of the triangle are (-3,-3), (-3,4) and (4,-3).

Hence, the side lengths of the triangle are 7 units, 7 units, and 7√2 units.

So, it is not similar to the graphed triangle.

{Since, the ratio of corresponding sides of the similar triangles are the same}

Now, in option B.

The vertices of the triangle are (-3,-3), (-3,5) and (4,-3).

Hence, the side lengths of the triangle are 7 units, 8 units, and 10.63 units.

So, it is not similar to the graphed triangle.

Now, in option C.

The vertices of the triangle are (-3,-3), (-3,4) and (3,-3).

Hence, the side lengths of the triangle are 6 units, 7 units, and 9.21 units.

So, it is not similar to the graphed triangle.

Now, in option D.

The vertices of the triangle are (-3,-3), (-3,5) and (3,-3).

Hence, the side lengths of the triangle are 6 units, 8 units, and 10 units.

So, it is similar to the graphed triangle.  

This is because the ratio of the corresponding sides of the given triangle and the graphed triangle are same and it is 2.(Answer)

Andrea, Justin, and Virginia went to an office supply store. Andrea bought 6 pencils, 7 markers, and 8 erasers. Her total was $1
olga2289 [7]

Answer:

x=0.25\,,\,y=1.75\,,\,z=0.25

Step-by-step explanation:

Let x,y,z denotes number of pencils, markers, erasers respectively.

For Andrea:

6x+7y+8z=15.75\,\,\,(i)

For Justin:

6x+8y+5z=16.75\,\,\,(ii)

For Virginia:

5x+5y+7z=11.75\,\,\,(iii)

On subtracting equations (i) and (ii), we get

(6x+7y+8z)-(6x+8y+5z)=15.75-16.75\\-y+3z=-1\\y-3z=1\\y=1+3z

Put y=1+3z in equation (i)

6x+7(1+3z)+8z=15.75\\6x+29z=8.75\,\,\,(iv)

Put y=1+3z in equation (iii)

5x+5(1+3z)+7z=11.75\\5x+22z=6.75\,\,\,(v)

Multiply equation (iv) by 5 and equation (v) by 6 and then subtract both the equations.

5(6x+29z)-6(5x+22z)=5(8.75)-6(6.75)\\13z=3.25\\z=\frac{3.25}{13}=0.25

Put z=0.25 in equation y=1+3z

y=1+3(0.25)=1.75

Put y=1.75\,,\,z=0.25 in equation (i)

6x+7(1.75)+8(0.25)=15.75\\6x+12.25+2=15.75\\6x=1.5\\x=0.25

Rebecca solved
Nuetrik [128]

No.

\sqrt{45}=3\sqrt{5}  \\2\sqrt{20} =2\sqrt5}

If you add them up you DO NOT GET 5\sqrt{5}. According to mathematics, it equals to 7\sqrt{5}.

How to solve -d/6+12=-7
Delicious77 [7]
IF you are solving for d:

isolate the D, do the opposite of PEMDAS.

-d/6 + 12 = -7

(subtract 12 from both sides)

-d/6 + 12 (-12) = -7 (-12)

-d/6 = -19

(multiply 6 to both sides)

-d/6(6) = -19(6)

-d = -19(6)

-d = -144

-d/-1 = -144/-1

d = 144

hope this helps

At what point on the curve x^2 + y^2 = 9 is the tangent line vertical?
Gemiola [76]

x² + y² = 9 is the equation of a circle with center (0, 0) and radius 3.

This puts the vertices at (-3, 0), (3, 0), (0, -3), and (0, 3).

When is the tangent line vertical? <em>when it passes through the x-axis.</em>

Answer: (-3, 0), (3, 0)
