distance away. Which target is easier to hit?

Answer: 16:24

Step-by-step explanation:

add the ratio so 2+3=5

Divide from 40 so 40/5=8

multiply by individual ratios

2*8:3*8= 16:24

Answer:

Step-by-step explanation:

The central angle is twice the inscribed angle (same arc).

The inscribed angle forms a supplementary angle with the missing one (opposite angles of the cyclic quadrilateral).

The missing angle is:

Answer:

Step-by-step explanation:

The tangent of the angle can be found using the identity for the tangent of the difference of angles.

  tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))

The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.

  tan(α) = -2/3

  tan(β) = 4/7

  tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))

  = (-14-12)/(21 -8) = -26/13 = -2

Then the magnitude of the angle between the vectors is ...

  arctan(2) ≈ 63.43°

Answer:3(−4)(−3) This the answr can u solve my question maybe?

The error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

The SSA congruence theorem only exist and holds true, only if the congruence non-included angles in both triangles are either obtuse or right angles and have two pairs of congruent sides.

Thus:

The two triangles given have a pair of non-included congruent angles that are less than 90 degrees.

Therefore, the error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

Answer:

(7,0) ---> (x = 7) and (y = 0)

Step-by-step explanation:

2x – 9y = 14

x= -6y +7     <-- (Substitute for x to above equation)

---------------------------------------------------------------------------------------------------------

2(-6y +7)– 9y = 14

-12y + 14 - 9y = 14    <-- combine like terms

-21y + 14 = 14  

        -14 = -14   <-- inverse operation on both sides

      -21y = 0     <-- Divide

          y = 0  <--- Substitute for y to get x  ↓

-------------------------------------------------------------------------------------------------------

2x – 9y = 14

2x – 9(0) = 14     <-- Substituted y from above

          2x = 14     <-- Divide

Answer:

A) 252pi

Step-by-step explanation:

The volume of a sphere is [tex]\frac{4}{3}\pi r^{3}[/tex]

First, let's find the diameter of the large sphere.

If D=12, then R=6

[tex]\frac{4}{3}\pi 6^{3}=288\pi[/tex]

Then, we need to find the volume of the smaller sphere

[tex]\frac{4}{3}\pi 3^{3}=36\pi[/tex]

[tex]288\pi -36\pi =252\pi[/tex]

Answer:

y+4=-2(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

y-(-4)=-2(x-(-1))

y+4=-2(x+1)

It looks like you have

tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = cot(x) + tan(x) + 1

but this is not an identity.

Take for instance x = 3π/4. Then

tan(3π/4) = -1

cot(3π/4) = -1

so that

tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = 0

while

cot(x) + tan(x) + 1 = -1

and of course 0 ≠ -1.

answer

600

Step-by-step explanation:

Step 1: If 82% of a number is 492, then what is 100% of that number? Setup the equation.

492/82%=Y/100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

82Y = 492 x 100

82Y = 49200

Y=49200100=600

Any two quadratic equations​.

Solution:

The general form of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

[tex]1x^2+1x+1=0[/tex]

[tex]x^2+x+1=0[/tex]

One quadratic equation is [tex]x^2+x+1=0[/tex].

For a=3,b=-1,c=5, we get

[tex]3x^2+(-1)x+5=0[/tex]

[tex]3x^2-x+5=0[/tex]

Therefore, the two quadratic equations are [tex]x^2+x+1=0[/tex] and [tex]3x^2-x+5=0[/tex].

Step-by-step explanation:

Hey There!

So where the given angles are is in a triangle called an isosceles triangle

In isosceles triangles to of the angles are congruent

The congruent angles are near the letters Q and R

we are given that angle 1 =50

so to find the missing angles we subtract 180 from 50 and divide by 2

180-50=130

130/2=65

so angle 2 = 65
