Samir walked 2 times as many hours as Rex walked.​

A ratio can be defined as the comparison of two or more numbers on the basis of  their sizes in relation to each other.

It also indicates how many times one number contains another.

Given that;

To determine the ratio, we have to divide Samir's walking hours by Rex's working hours

= 10/ 3 ÷ 5/ 3

Take the inverse of the divisor and multiply

= 10/ 3 × 3/ 5

= 2 hours

Thus, Samir walked 2 times as many hours as Rex walked.​

My answer to part (a) relates to the explicit formula in an  n  =  n+6  n  a=  n+6  n.

a=  n+6  n

Step-by-step explanation:

n=an−1−5

Step 1: Flip the equation.

an−6=n

Step 2: Add 6 to both sides.

an−6+6=n+6

an=n+6

Step 3: Divide both sides by n.

an  n  =  n+6  n  a=  n+6  n

The expression that shows how to rewrite 4 − 5 using the additive inverse is (a)

The expression is given as

4 - 5

The law of additive inverse states that

x + (-x) = 0

This means that x and -x are additive inverses

Using the above as an illustration,

4 - 5 can be rewritten as 4 + (-5)

And the above implies that the number line moves 4 points to the right and 5 points to the left

Hence, the expression that shows how to rewrite 4 − 5 using the additive inverse is (a)

A sequence is a geometric sequence if all the numbers of a list are found by multiplying the preceding term by the common ratio r of that sequence. Sigma notation can represent the sum of a finite number of terms (although higher mathematics will tell you how it works for infinite numbers as well).

Now the given problem is,

calculate ∑ n=1, 4, 2n

∑n=1 , 4 , 2n

Since the bounds are finite, the number of terms is finite as well, and we just calculate the sum by summing up the terms.

(∑n=1 4 ,2n) = (2+4+8+16) (∑n=1 4, 2n) = (2+4+8+16)

(∑n=1 4 ,2n) = (30) (∑n=1 4, 2n) = (30)

Hence,

∑n=1 4, 2n=30 ∑n=1 4, 2n=30

Answer:

∑n=1 4, 2n=30

A normal polyhedron shape is defined as a polyhedron having a symmetry group that acts transitively on the flags. Regular polyhedral are highly symmetrical because they are all edge-transitive, corner-transitive, and face-transitive. Many different equivalent definitions are used in classical contexts. There are many definitions in mathematics defining a regular polyhedron, and is that the faces of a polyhedron are nothing but congruent regular polygons that are constructed in the same way around each vertex of the polyhedron. So the polyhedron having faces/sides that are congruent with regular polygons and the exact number of faces that meet at each vertex is called a regular polyhedron.

Euler's polyhedron formula describes the relationship between the number of vertices, edges, and faces of a three-dimensional polyhedral shape.

V-E+F=2 gives Euler's polyhedron formula.

The amount of money after 10 months will be $67.2. The number of months (n) that it takes to have at least $100 will be 2 years or 24 months.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

[tex]\rm A = P \left (1 + r \right ) ^{t}[/tex]

Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of months.

I keep my savings in a bank account that, at the end of each month, gives me 3% interest on the balance. (If I withdraw my funds before the end of the month, I forfeit the interest I would have accrued.) I opened the account using the $50 I received as a birthday gift.

The amount of money after 10 months will be

A = 50 (1 + 0.03)¹⁰

A = 50(1.03)¹⁰

A = 50 x 1.344

A = $67.2

The number of months (n) that it takes to have at least $100 will be

100 = 50 (1.03)ⁿ

If Jenny's Bakery sells carrot muffins at 2 each and the electricity to run the oven is 120 per day and the cost of making one carrot muffin is 1.40, then the number of muffins needed to be sold each day to break even is equal to 200.

The number of muffins needed to be sold each to break even can be determined by forming a linear equation.

A linear equation, sometimes also referred to as a first-degree equation can be described as an equation that contains variables that have the maximum power of not more than one.

The linear equation for this problem will be,

Cost of electricity to run the oven + Cost of making x number of muffins = Sale price of x number of muffins

120 + 1.40 (x) = 2 (x)

Here x is equal to the number of muffins

Rearranging the equation,

120 = 2(x) - 1.40 (x)

120 = 0.6 (x)

120/0.6 = x

x = 200

Hence, 200 muffins are needed to be sold each day to break even.

a. 95 b. kite

Step-by-step explanation:

a. all quadrilaterals add up to 360° angle with all angles, so 100+100+65=265, 360-265=95.

b. most quadrilaterals have 2 pairs of 2 equilateral angles, and this is one of the only ones that doesnt.

Answer:

a)  95°

b)  Kite

Step-by-step explanation:

Theorem:  Interior angles of a quadrilateral sum to 360°.

Given angles:

Let x be the unknown angle.

⇒ 100° + 65° + 100° + x = 360°

⇒ 265° + x = 360°

⇒ 265° + x - 265° = 360° - 265°

⇒ x = 95°

Therefore, the fourth angle is 95°.

A kite is a quadrilateral that has one pair of congruent opposite angles.

Therefore, as two of the interior angles of the given quadrilateral are equal, the shape may be a kite.

Answer:

it is not factorable

Step-by-step explanation:

Answer:

1) the center is (3,4), radius is 3. 3)  ( x − 2 )^2 + ( y − 14 )^2 = 9, 5) the center is (12,5), the radius is 4

Step-by-step explanation:

For the graphs just look for the middle point, and thats essentially your center, and the radius is how many units the edge of the circle is to the center. So for 1 the center would be (3,4) and the radius 3. For problem 3 use the equation  ( x − a )^2 + ( y − b )^2 = r^2, where you substitute the radius for r, your x center coordinate as a, and your y coordinate as b. In problem 5, use 12 as your x value for the center coordinate, and 5 as your y value. Then just take the root of 16 to get your radius, and apply that to the other problem. Hope this helps :)

The linear equation with a direct variation function always passes through the origin.

What are direct variation functions?

The direct variation function defines a linear function of the form y = kx, where y varies as a multiple of x and x 0. These always follow the origin test.

Calculation

Yes, the method will always work because the linear equations having direct variations are those equations which always pass through the origin.

For example: If we consider an equation y = 3x. Then, it will always pass through the origin as y changes with respect to some multiples of x.

Hence, the direct variation function always passes through the origin.
