Answer:

[tex]r \geqslant - 16[/tex]

Step-by-step explanation:

[tex] \frac{ - 10 + r}{2} \geqslant - 13[/tex]

multiply both sides by 2:

[tex] - 10 + r \geqslant - 26[/tex]

add 10 on both sides:

[tex]r \geqslant - 16[/tex]

Answer:

[tex]r \ge -16[/tex]

Step-by-step explanation:

To solve any equation/inequality:

1. get the variable to show up exactly once

2. isolate it

[tex]\frac{-10+r}{2} \ge -13[/tex]

Multiply both sides by 2 and simplify (note that we're multiplying by a positive, not a negative, so the direction of the inequality stays the same, whereas multiplying or dividing by a negative would have changed the direction of the inequality)

[tex]\frac{-10+r}{2} *2 \ge -13 *2[/tex]

[tex]-10+r \ge -26[/tex]

Add 10 to both sides, and simplify

[tex](-10+r)+10 \ge (-26)+10[/tex]

[tex]r \ge -16[/tex]

The ingredients Rose needs to make 5 short bread fingers are;

Recipe for 30 shortbread fingers.

To determine the recipe needed for 5 short bread fingers ; divide 30 by 5

= 30/5

= 6

This means, each recipe needed for 30 short bread fingers will be divided by 6 to achieve recipe needed for 5 short bread fingers.

Therefore,

Recipe needed for 5 short bread fingers:

Butter = 120 g / 6

= 20 g

Sugar = 60 g / 6

= 10 g

Co-interior angles are the two angles that occur between two parallel lines intersected by a transversal.

The sum of the co-interior angles is 180 degrees.

The value of x is 15.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

Co-interior angles are the two angles that occur between two parallel lines intersected by a transversal.

The sum of the co-interior angles is 180 degrees.

(8x + 9)° and 51° are co-interior angles.

So,

8x + 9 + 51 = 180

8x = 180 - 60

8x = 120

The actual price of an item is $1371.49.

Given that, the discount percentage is 12.5% and the selling price is $1200.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Let the actual price be x.

Now, x-12.5% of x =1200

⇒ x- 12.5/100 ×x=1200

⇒ x- 0.125x=1200

⇒ 0.875x=1200

⇒ x=1200/0.875

Using the proportion rule, the ratios 1/3 and 2/5 does not form a proportion.

In the given equation,

We have to check the ratios 1/3 and 2/5 form a proportion or not.

As we know that proportion is a ratio in which both ratios are equal to each other.

So to check whether the given statement is proportion or not we put both equation equal to each other.

So the ratios are 1/3 and 2/5.

Now checking the proportion.

1/3=2/5

Multiply by 15 on both side.

1/3 ×15=2/5 ×15

Simplifying

1×5=2×3

The probability of choosing a box and picking two quarter coins in a row is 1/108

Probability is the branch concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1. 0 indicates impossibility of the event and 1 indicates certainty.

Probability= sample space / total possible outcome

therefore probability of choosing two quarters in a row = 1/6×1/6= 1/36

The probability of choosing the first box =1/3

Therefore the probability of choosing the first box and picking two quarters In a row is 1/36×1/3= 1/108.

Since box two contain no quarter and box three has only one quarter , the probability of choosing two quarters in a row is 0.

Therefore the probability of choosing a box at random and picking two quarters in a row is 1/108.

Graph will shift from(0,0) to (3,4) after the shifting happens due to change in expressions of the parent function.

Graph transformation is the process by which an parent graph, or graphed equation, is changed to produce a variation of the proceeding graph. It's a common type of problem in algebra, specifically the modification in algebraic equations.

The deduced parent function is [tex]\sqrt{x}[/tex]

So, Domain= (0 , ∞)

Answer:

BC = 7.9 cm

Step-by-step explanation:

To construct triangle ABC:

The equation of the parabola from the vertex is f(x) = -3(x - 5)² + 9

The equation of the function is given as

f(x) = 3x²

Also, we have

Vertex = (5, 9)

The form of the equation is given as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

This means that

Vertex = (h, k) = (5, 9)

Substitute (h, k) = (5, 9) in the equation f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 5)² + 9

This also means that

f(x) = -3(x - 5)² + 9

The -3 is gotten from f(x) = -3x²

Hence, the equation of the parabola is f(x) = -3(x - 5)² + 9

Unit rate of the table is 2.

The units of concentration and rate are always going to be molars per second. We now understand that molar per second is equal to k times molar in units. An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.

The required expression 16m + 6n - 8 represents the perimeter of the triangle. which is the correct answer would be option (D).

A triangle has side lengths of (7m - 2) centimeters, (9m - 5) centimeters, and (6n - 1) centimeters.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

The perimeter of the triangle = (7m - 2) + (9m - 5) + (6n - 1)

Rearrange the terms likewise in the above equation,

The perimeter of the triangle = 7m + 9m + 6n - 2 - 5 - 1

Apply the arithmetic operation to get the required expression

The perimeter of the triangle = 16m + 6n - 8
