the diameter of circle A is 2.3 units. Find the circumference of the circle

Answer:

  12 1/2 pounds

Step-by-step explanation:

You want to know the total weight of 50 hamburger patties that weigh 1/4 pound each.

The weight of 50 patties will be the sum of their weights. That sum is most easily figured using multiplication.

  (1/4 lb) +(1/4 lb) +(1/4 lb) +... +(1/4 lb) . . . . 50 repetitions

  = 50 × (1/4 lb)

  = (50/4) lb = 12.5 lb

Rita bought 12 1/2 pounds of hamburgers.

Answer:

-

Null hypothesis             H₀ : σ² ≤ 0.02

Alternative hypothesis Hₐ  : σ² > 0.02

- Chi Square = 51.2

- p-value = 0.1104

- since the calculated p-value ( 0.1104 ) is greater than the level of significance ( 0.05 ).

We fail to reject null hypothesis.

- So at, 5% level of significance, there is no evidence to support that the variance in the cereal box fillings is designed to be 0.02 or less.

Step-by-step explanation:

Given the data in the question;

filling variance for boxes of cereal is designed to be .02 or less

sample size n = 41 boxes

standard deviation S = 0.16 ounces

level of significance = 0.05

Hypothesis;

Null hypothesis             H₀ : σ² ≤ 0.02

Alternative hypothesis Hₐ  : σ² > 0.02

{ Upper tail test }

Test statistics;

Chi Square = [ ( n-1 ) × S² ] / σ²

Chi Square = [ ( 41-1 ) × (0.16)² ] / 0.02

Chi Square = [ 40 × 0.0256 ] / 0.02

Chi Square = 1.024/ 0.02

Chi Square = 51.2

Degree of freedom df = n - 1 = 41 - 1 = 40

Chi square value at 0.05  and df of 40 = 55.7585

p-value = 0.1104

since the calculated p-value ( 0.1104 ) is greater than the level of significance ( 0.05 ).

We fail to reject null hypothesis.

So at, 5% level of significance, there is no evidence to support that the variance in the cereal box fillings is designed to be 0.02 or less.

Total surface area of cone is 176π

Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.

Hence surface area of curved surface of a cone is π×8×14=112π .

As surface area of base is π×82=64π .

Hence total surface area is 112π+64π=176π

The surface area of the given cone is 552.64 units²

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Given that, a cone has a radius of 8 and slant height of 14 units, we need to find its surface area,

The surface area of cone = π ·r²+ π·r·l, where l is the slant height,

So,

SA = (3.14 × 8²) + (3.14 × 8 × 14)

= 200.96 + 351.68

= 552.64

Hence, the surface area of the given cone is 552.64 units²

Answer:

f(x) = - 2x + 4

Step-by-step explanation:

Since we are only trying to move the graph up 3 units, the slope does not change. So, it would be -2.

We also know that the 1 in f(x)= -2x + 1 is the y-intercept (y=mx+b). But again, we are moving the graph 3 units up, so we have to add 3. That makes it 4 (3+1=4).

So, the new equation would be f(x) = -2x + 4

Step-by-step explanation:

it simply means that g(x) is f(x) just shifted 3 units upwards.

that means nothing else changes, only whatever y result f(x) produces is increased by 3.

so,

g(x) = f(x) + 3 = -2x + 1 + 3 = -2x + 4

therefore, as domain and range were the whole set of real numbers, the addition of 3 does not make any difference in relation to infinity. so, they remain unchanged.

the slope stays the same (g(x) is simply a parallel line to f(x)).

the y-intercept (the y-value when x = 0) also increases by 3, and is 4.

the x-intercept (the x-value when y = 0) changes :

0 = -2x + 4

2x = 4

x = 2

the x-intercept is 2.

Answer:

The inequality is: \(5(x - 2) \geq 35\)

The solution is: \(x \geq 9\)

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle with length l and width w is given by:

A = lw

In this question:

Width 5 feet.

Length x - 2.

For which the area of the rectangle will be at least 35 square feet

Equal or greater than 35. So

\(5(x - 2) \geq 35\)

\(5x \geq 45\)

\(x \geq \frac{45}{5}\)

\(x \geq 9\)

B

Step-by-step explanation:

you have to divide the numbers to see if they equivalent.

Answer:

\( |w-0.3| \leq 0.0003\)

And solving we got:

\( -0.0003 \leq w-0.3 \leq 0.0003\)

\(0.3-0.0003 \leq w \leq 0.3+0.0003\)

\( 0.2997 \leq w \leq 0.3003\)

Step-by-step explanation:

For this case we can define the following notation:

\( W\) represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

\( |w-0.3| \leq 0.0003\)

And solving we got:

\( -0.0003 \leq w-0.3 \leq 0.0003\)

\(0.3-0.0003 \leq w \leq 0.3+0.0003\)

\( 0.2997 \leq w \leq 0.3003\)

\(2^{x}\) + \(\frac{2}{3}\),  \(2^{x}\), \(2^{x}+2\), \(2^{x}-3\) are examples of exponential parent function.So all of the given options are true.

Parent function:  The most basic function in a family of functions is the parent function. A family of functions is a collection of functions that have similar graph shapes because they all have the same greatest degree.

Four graphs that illustrate the U-shaped graph, or parabola, are displayed in the graph above. We can classify them as belonging to the same family of functions since they all have the same highest degree of two and the same form.

Exponential parent function: Algebraic expressions appear in the exponent of exponential functions. The formula for its parent function is y = \(b^{x}\), where b can be any non-zero constant.

For above definitions we can conclude that all options given to us are exponential parent function.

Option (b) is the correct answer: Perpendicular segments.

Perpendicular rays, perpendicular segments, perpendicular lines, and parallel lines are important concepts in geometry that describe the relationship between lines and line segments.

1. Perpendicular Rays: Perpendicular rays are two rays that intersect at point and form a right angle (90 degrees) at the point of intersection. The rays extend indefinitely in opposite directions from the point of intersection.

2. Perpendicular Segments: Perpendicular segments are line segments that intersect at a right angle. They share a common endpoint but do not extend indefinitely like rays. The right angle is formed at the point of intersection.

3. Perpendicular Lines: Perpendicular lines are lines that intersect at a right angle. They continue indefinitely in opposite directions and form four right angles at the point of intersection. Perpendicular lines are often denoted by a symbol ⊥.

4. Parallel Lines: Parallel lines are lines that never intersect. They remain equidistant from each other at all points. Parallel lines have the same slope and do not converge or diverge. In Euclidean geometry, parallel lines are denoted by a double vertical line symbol (||).

Understanding these concepts is fundamental in geometry as they help define angles, shapes, and spatial relationships. The properties of perpendicular and parallel lines play a crucial role in various geometric theorems and applications.

Cheryl would need 240 tablespoons of cornstarch to make the green slime recipe 15 times.

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

To make the green slime recipe 15 times, Cheryl would need 15 times the amount of cornstarch listed in the recipe.

If 1 cup of cornstarch is needed for one recipe, then 15 cups of cornstarch would be needed to make the recipe 15 times.

Since there are 16 tablespoons in 1 cup, the number of tablespoons of cornstarch needed to make the recipe 15 times is:

= 16 tablespoons/cup x 15 cups

= 240 tablespoons.

So, Cheryl would need 240 tablespoons of cornstarch to make the green slime recipe 15 times.

Step-by-step explanation:

The 50th term of the arithemetic sequence 40, 36, 32, 28, 24, .. will be - 156 which is the correct answer to this question.

Here In this question, we need to find the 50th term of this sequence and for that, we have to find the common difference in the values.

Here we can notice that each term is getting smaller by 4 so the common difference here is -4.

Equation used :

an = a1 + (n - 1) * d

where

Given :

a1 = 40

d = -4

n = 50

Putting these values into the formula :

a50 = 40 + (50 - 1) × (-4)

On simplifying by the BODMAS rule,

a50 = 40 + 49 × (-4)

a50 = 40 - 196

a50 = -156

Hence -156 is the 50th term of this arithmetic sequence.

The value of 14.5% of 1,800 is 261 by using the concept of percentage.

In mathematics, a percentage is a value or ratio expressed as a fraction of 100.

The term percent is derived from the Latin per centum, which means "hundred" or "by the hundred." The sign for "percent" comes from the Italian expression per cento, which means "for a hundred." The "per" was frequently shortened as "p." and finally disappeared entirely. The "cento" was reduced to two circles divided by a horizontal line, from which the present "%" symbol was derived.

A % is a relative figure that indicates one-tenth of a quantity. One percent (symbolized 1%) is the one-hundredth part; consequently, 100 percent denotes the complete amount, and 200 percent specifies twice the supplied amount.

Given,

14.5% of 1,800

=(14.5/100)×1800

=261
