Answer:

1 and 5 are complementary angles

Step-by-step explanation:

A complementary angle is either of two angles whose sum is 90, meaning two opposite angles that add up to 90 degrees.

If you look at angle 3, you see that it is a right angle which is 90 degrees already so any answer containing 3 and another angle is incorrect.

Why 1 and 5 is the correct answer:

the angles 1 and 2 are right next to 3 which is a 90-degree angle, meaning that 1 and 2 add up to 90. angle 5 is opposite of 2 which means that angle 5 and 2 are equal.

So the 1 and 5 would add up to 90, making it the right answer.

Hope this helps you :)

Answer:

0.1042 meters per year

Step-by-step explanation:

Find the unit rate by dividing 0.25 by 2.4

0.25/2.4

= 0.1042

So, the unit rate is approximately 0.1042 meters per year

Answer:

correct

Step-by-step explanation:

Angle-Side-Angle (ASA) Postulate:

If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

<C = <G

CA = GD

<A = <D

Triangle CAT = Triangle GDO are the two triangles that are congruent by the ASA Postulate.

Answer:

[tex]y=-\frac{1}{9}(x-2)^2-3[/tex]

Step-by-step explanation:

When a quadratic equation is in the form [tex]y=a(x-h)^2+k[/tex] (vertex form):

Therefore, if the vertex of the function is at (2,-3), h needs to be 2 for [tex](x-h)^2[/tex]  to equal 0 and k needs to be -3. The only equation that displays this is G:

[tex]y=-\frac{1}{9}(x-2)^2-3[/tex]

I hope this helps!

Answer:

1/10

Step-by-step explanation:

First, convert your numbers to decimals.

2.5 cans of paint cover 0.25 area of a room.

Equation:

2.5=0.25

If you divide 2.5 by 5, you'll get 0.5.

But what you do to one side, you do it to the other.

0.25÷5= 0.05

So now you have your new equation

0.5=0.05

since you want 1 can of paint, multiply it by 2.

1= 0.1

convert it back to fraction: 1/10

Answer:

step by step explanation:

Step by step workout

step 1 Address the formula, input parameters and values

Formula:

nPr =n!

(n1! n2! . . . nk!)

Input Parameters & Values:

Total number of alphabets (n) & subsets (n1, n2, . . nk) in the word "MATHEMATICS"

n = 11

Subsets : M = 2; A = 2; T = 2; H = 1; E = 1; I = 1; C = 1; S = 1;

n1(M) = 2, n2(A) = 2, n3(T) = 2, n4(H) = 1, n5(E) = 1, n6(I) = 1, n7(C) = 1, n8(S) = 1

step 2 Apply the input parameter values in the nPr formula

=11!

(2! 2! 2! 1! 1! 1! 1! 1! )

=1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11

{(1 x 2) (1 x 2) (1 x 2) (1) (1) (1) (1) (1)}

=39916800

8

= 4989600

In 4989600 distinct ways, the letters of word "MATHEMATICS" can be arranged.

Answer:

(5 - 1)^2 + (1 - 1)^2 = 4^2

Step-by-step explanation:

Circle equation: ( x - h )^2 + ( y - k )^2 = r^2

(h,K) is the coordinate of the center.

Center: (1,1)

(x,y) choose a point that could be the radius. (I choose the one on the top left side).

Point: (5,1)

Diameter: 8

Radius: 4

Plug in:

( x - h )^2 + ( y - k )^2 = r^2

(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)

Solve to see if it's true,

(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)

4^2 + 0^2 = 4^2

16 = 16 (This is true, therefore, the equation is correct).

Answer:(x-1)^2 + (y-1)^2=16

Answer:

Step-by-step explanation:

Consider the parent function:

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

Since all the options have 1/20 as a coefficient, our function is:

This is option B

Answer:

40% price reduction

Step-by-step explanation:

The tickets were reduced by 40% because 20 is 2/5 or 40% of 50 and that was the amount of the price reduction.

Answer:

%40

Step-by-step explanation:

Here is why:

Because every dollar coutns as 2% of the price so 20 * 2 is 40 and you will get %40!

Any Questions?

Answer:

Option B

Step-by-step explanation:

It's given that ΔE'F'G' is the translated image of ΔEFG.

Let the ΔEFG has been translated 'h' units on x-axis and moved by 'k' units on y-axis.

Let's choose a point E having coordinates (-5, -7)

By the rule of translation, coordinates of the image point E' will be,

E(-5, -7) → E'(-5 + h, -7 + k)

Coordinates of the image point E' → (-9, 4)

Comparing both the coordinates of E',

E'(-5 + h, -7 + k) = E'(-9, 4)

-5 + h = -9

h = -9 + 5

h = -4

-7 + k = 4

k = 4 + 7

k = 11

Therefore, rule for the translation will be,

E(-5, -7) → E'(-5 - 4, -7 + 11)

(x, y) → (x - 4, y + 11)

Option B is the answer.

Answer:

1,075 ft

Step-by-step explanation:

So you need to find area

15 x 25 =375 ft

35 x 20 = 700 ft

add together to get total of both

700 + 375 = 1,075
