Hey there!

The answer to your question is  45\frac{9}{10}

We can find this by simply plugging in the "r" value into the given equation.

46 + \frac{1}{5} (\frac{-1}{2})

Now we evaluate the equation:

46 + \frac{1}{5} (\frac{-1}{2})

46 + \frac{-1}{10}

45\frac{9}{10}

Hope this helps and have an amazing day!

Answer:

45\frac{9}{10} or 45.9

Step-by-step explanation:

All we have to do here is substitute the given value of r into the given expression. Therefore, after substituting r=-\frac{1}{2} into 46+\frac{1}{5}r, we get:

46+\frac{1}{5}r

= 46+\frac{1}{5}*(-\frac{1}{2} ) (Substitute r=-\frac{1}{2} into 46+\frac{1}{5}r)

=46-\frac{1}{10} (Multiply)

=45\frac{9}{10} or 45.9 (Simplify)

Hope this helps!

function in c that takes three decimal numbers as inputs and finds the sum of those inputs and returns the sum
kozerog [31]

The function that takes three decimal numbers as inputs and finds the sum of those inputs and returns the sum has been given below

What is programming?

Program is the set of instructions given to the computer so that the computer can execute those instructions. The act of writing program is called programming.

The program has been shown below

#include<stdio.h>

using namespace std;

int main()

{

double n1, n2, n3;

double s;

printf("Enter first numbers");

scanf(%lf, &n1);

printf("Enter second numbers");

scanf(%lf, &n2);

printf("Enter third numbers");

scanf(%lf, &n3);

s = n1 + n2 + n3;

printf("Sum = %f", s);

return 0;

}

The number of students in a school's math club is ten less than twice the number of students in the art club. Let a represent th
Alborosie

Answer:    2a - 10

Step-by-step explanation:

a represents the number of students in the art club.

The number of students in a school's math club is ten less than twice the number of students in the art club.

ten less = - 10

twice the number of students in the art club = 2*a

2a - 10 = the number of students in the math club

Why does a rectangle with different side lengths have only 2 lines of symmetry?
ICE Princess25 [194]

Answer:

C. all four angles are congruent, and opposite sides are congruent for a horizontal and vertical line of reflection

Step-by-step explanation:

A. isn't correct because all four sides aren't congruent, only the pair of opposite sides are congruent. Sense only opposite side are congruent you can only reflect the opposite sides onto each other and not diagonally meaning B. and D. are incorrect leaving C. all four angles are congruent, and opposite sides are congruent for a horizontal and vertical line of reflection as the correct answer

Need help with this slide about proofs explanation would be nice aswell.
Sunny_sXe [5.5K]

Answer:

1. AB ~= DF

2. Definition of Congruent

3. Reflexive Property of Congruency

4 BD=BD

6. AB+BD=AD; DF+BD=BF

7. Substitution Property of Equality

8. Definition of Congruent

Step-by-step explanation:

1. The given always goes first, and that's the first reason, so AB ~= DF must be the first statement (that should be the congruency symbol).

2. The definition of congruent is that if they are congruent then they are equal. Since that statement made two congruent lines equal, it must be the definition.

3. The reflexive property means something is congruent to itself, and BDis BD, therefore it is the reflexive property.

4. Remember if something is congruent then it is equal.

6. The segment addition postulate states that if we are given two points on a line segment, then AB+AC=AC.

7. In this statement AD was substituted for DF+BD. This can be done because of AB=DF and BD=BD as aforementioned.

8. If two things are congruent then they are equal by definition of congruency.
