The percent error is 4.17 %

Solution:

To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz

When Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz

To find: percent error

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

[tex]\% \text { error }=\frac{\text {approximate value}-\text {exact value}}{\text {exact value}} \times 100[/tex]

Here approximate value = 2.5 oz and exact value = 2.4 oz

[tex]\% \text { error }=\frac{2.5-2.4}{2.4} \times 100\\\\\% \text { error }= \frac{0.1}{2.4} \times 100 = 4.17[/tex]

Therefore percent error is 4.17 %

Answer:

b = 6.7cm

Step-by-step explanation:

The law of sines is:

[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex] OR [tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]

Each section represents an angle (capital) and its opposite side (lowercase). When you use it, only use two sections at a time. You may have one missing piece of information when using it. Use the formula that puts the missing information in the numerator (top).

This problem:

We are given one set of information, 8cm and 55°. This can be "a" and "A" (not labelled).

We need angle B to find side b.

Since we are given two of the three angles in the triangle, and the sum of all interior angles of any triangle is 180°, we can find the missing angle.

∠B = 180° - (∠A + ∠C)

∠B = 180° - (55° + 82°)

∠B = 43°

Use the law of sines with sections "A" and "B", with the lowercase letters in the top.

[tex]\frac{a}{sinA} =\frac{b}{sinB}[/tex]  Substitute known measurements

[tex]\frac{8cm}{sin(55)} =\frac{b}{sin(43)}[/tex]  Rearrange to isolate "b"

[tex]b = \frac{8cm}{sin(55)}X{sin(43)}[/tex]  Solve, degree mode on calculator

[tex]b = 6.660...cm[/tex] Exact answer

[tex]b = 6.7cm[/tex] Rounded to nearest tenth

Therefore side b is 6.7cm.

Answer:

m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)

Step-by-step explanation:

In the diagram. check attach image

m∠A + m∠B + m∠C + m∠D = 360º.

Every quadrilateral can be decomposed (cut apart) into two triangles, each of whose angles' measures sum to 180º.

m∠A + m∠1 + m∠ 3 = 180º

m∠C + m∠2 + m∠4 = 180º

m∠A+m∠1+m∠3+m∠C+m∠2+m∠4 = 360º

therefore :

m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)

Given: Nails cost is $2.75 per pound

           Screw cost is $3.25 per pound

           Jerry has only $500 to spend on nails and screws.

           x represent quantity of nail bought and y represent quantity of screw    bought.

As given we know that Jerry has only $500 to spend, so the total cost has to be less than or equal to $500. It cannot go more than $500.

Remember, Total cost= [tex]\textrm{cost of goods per pound}\times quantity[/tex]

Now, Inequality to represent the cost of buying nails and screw.

[tex]\$2.75\times x\ pounds+ \$3.25\times y\ pounds\leq \$ 500[/tex]

Length of CD is 10 inches

Solution:

The diagram is attached below

Given that, Circle A and circle B are congruent

CD is a cord of both circles

AB = 24 inches

Radius = 13 inches

To find: length of CD

Draw a straight line connecting A and C

AC represents the radius of circle. Also given that radius is 13 inches, So AC = 13 inches

Given in question that AB = 24 inches

Therefore from figure, AO = AB/2 = 24/2 = 12

AO = 12

Let "b" be the length of CO

Therefore, CD = CO + OD = b + b

AOC forms a triangle, so we can use pythogoras theorem

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

By above definition for triangle AOC

[tex]AC^2 = AO^2 + OC^2[/tex]

Substituting AC = 13 and AO = 12 and OC = b

[tex]13^2 = 12^2 + b^2\\\\b^2 = 169 - 144\\\\b^2 = 25\\\\b = 5[/tex]

Thus length of CD is:

CD = b + b = 5 + 5 = 10

Thus length of CD is 10 inches

Answer:

∠CPB is an acute angle.

Step-by-step explanation:

Firstly, lets go over what an acute angle is. An acute angle is any angle that is less than 90°.

In the problem, we are told that ∠APE is a right angle. This means that it is 90°.

As ∠APE and ∠BPD are vertical angles, they must have the same measure. This means that ∠BPD is also 90°

As ∠BPD has the line PC in the middle of it, this angle could be split into ∠CPB and ∠CPD. These two angles must add up to be the same as ∠BPD, which is 90°. As these two angles must add to be 90° they must be less than 90°. This means that both ∠CPB and ∠CPD are acute angles.

As ∠CPD is not one of the options for the question, ∠CPB is the only correct answer.

Acute angles measure less than 90°. Among the options, only C) Angle CPB fulfills this condition. It's the only angle clearly smaller than a right angle in the image.

An acute angle is an angle that measures less than 90 degrees. In the image you sent, only one of the angles measures less than 90 degrees.

-angle APE is a right angle, which measures exactly 90 degrees.

-angle CPE and angle APC are both obtuse angles, which measure more than 90 degrees but less than 180 degrees.

-angle CPB is the only angle that measures less than 90 degrees, so it is the only acute angle.

Therefore, the answer is C) Angle CPB.

The solutions for ‘x’ in the given equation are – 3  and  - 7

Step-by-step explanation:

Given equation:

                   [tex]x^{2} + 10 x + 21 = 0[/tex]

To find the ‘x’ value, try to factor, because in this case it works, it's fast. By using factor method, we get

                    (x + 3) (x + 7) = 0  (adding both value we get 10 and multiply as 21 as in equation and check with signs also while factoring)

                     x = - 3, -7

Verify above values by multiply both terms,

                     (x + 3) (x + 7) = 0

                [tex]x^{2} + 7 x + 3 x + 21 = 0[/tex]

                [tex]x^{2} + 10 x + 21 = 0[/tex] (so values obtained from factor method are correct)

Or, can use quadratic formula, for [tex]a x^{2} + b x + c=0[/tex], the solutions are given by:

                      [tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

In the given equation, a = 1, b = 10, c = 21, apply these in above formula

                     [tex]x=\frac{-10 \pm \sqrt{10^{2}-(4 \times 1 \times 21)}}{2(1)}=\frac{-10 \pm \sqrt{100-84}}{2}[/tex]

                     [tex]x=\frac{-10 \pm \sqrt{16}}{2}=\frac{-10 \pm 4}{2}[/tex]

So,

When  [tex]x=\frac{-10+4}{2}=\frac{-6}{2}=-3[/tex]

When [tex]x=\frac{-10-4}{2}=\frac{-14}{2}=-7[/tex]

Hence, the values for ‘x’ are - 3 and - 7

The digit in the hundredths place of the number 9.014 is 1. Significant figures and rounding concepts determine that if the digit in the thousandths place is 5 or greater, the hundredths place digit is rounded up.

Explanation:

The digit in the hundredths place of the number 9.014 is 1. When dealing with decimal numbers, the first place to the right of the decimal point is the tenths place, the second place is the hundredths place, and so on. In the context of significant figures and rounding, if we need to round a number to the hundredths position, and the digit in the thousandths place (the third position to the right of the decimal) is 5 or greater, we round the hundredths digit up.

For example, if the calculator answer is 921.996 and we need to round to the hundredths place, we look at the thousandths place digit. Since it is greater than 5, we round up, changing the answer to 922.00.

The area of a 2D form is the amount of space within its perimeter. The width of the rectangle is 10/7 miles.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of a rectangle is the product of its length and its width, therefore, the width of the rectangle can be written as,

Area = Length × Width

Width = Area / Length

Given the area of the rectangle is 6/7 square miles, while the length of the rectangle is 3/5 miles, therefore, the width of the rectangle is,

Width = (6/7)/(3/5)

Width = (6×5)/(7×3) = 10/7

Hence, the width of the rectangle is 10/7 miles.

Option b) 36 over 25 is correct

That is given expression is equivalent to [tex]\frac{36}{25}[/tex]

Step-by-step explanation:

Given expression can be written as below:

[tex](\frac{7\times 3\times 2}{7\times 5})^2\times \frac{7^0}{5^{-3}}\times 5^{-9}[/tex]

To find the value of given expression:

[tex](\frac{7\times 3\times 2}{7\times 5})^2\times \frac{7^0}{5^{-3}}\times 5^{-9}=(\frac{6}{5})^2\times (\frac{1}{5^{-3}})^3\times \frac{1}{5^9}[/tex]

Answer:

b. m can be any positive real number.

Step-by-step explanation:

The value of m can be any positive real number. The correct answer is option b) m can be any positive real number.

Step 1

To determine the value of m that makes the ranges of [tex]\( f(x) = m^x \)[/tex] and [tex]\( g(x) = x^m \)[/tex] the same, we need to analyze the ranges of both functions.

Analyzing [tex]\( f(x) = m^x \)[/tex] :

- If [tex]\( m > 0 \)[/tex], [tex]\( m^x \)[/tex] is an exponential function.

 - For [tex]\( m > 1 \)[/tex], [tex]\( f(x) = m^x \)[/tex] increases and its range is [tex]\( (0, \infty) \)[/tex].

 - For [tex]\( 0 < m < 1 \)[/tex], [tex]\( f(x) = m^x \)[/tex] decreases and its range is also [tex]\( (0, \infty) \)[/tex].

Step 2

Analyzing [tex]\( g(x) = x^m \)[/tex] :

- The range of [tex]\( x^m \)[/tex] depends on whether m is positive or negative:

 - For positive m :

   - When [tex]\( m = 1 \)[/tex], [tex]\( g(x) = x \)[/tex], the range is all real numbers, [tex]\( \mathbb{R} \)[/tex].

   - When [tex]\( m > 1 \)[/tex] or [tex]\( 0 < m < 1 \)[/tex], the function is defined for [tex]\( x > 0 \)[/tex] and its range is [tex]\( (0, \infty) \)[/tex] .

 - For negative m :

   - The function [tex]\( x^m \)[/tex] is undefined for [tex]\( x = 0 \)[/tex] and for negative x, and thus its range is [tex]\( (0, \infty) \)[/tex].

Both [tex]\( f(x) = m^x \)[/tex] and [tex]\( g(x) = x^m \)[/tex] have the range [tex]\( (0, \infty) \)[/tex] for any positive [tex]\( m \)[/tex], but for any negative m, [tex]\( g(x) \)[/tex] is undefined at zero and for negative x.

The value of m can be any positive real number (option b).

Complete question : If the range of f(x) = ^mx and the range of g(x) = m ^ x are the same, which statement is true about the value of m?

a) m can only equal 1.

b) m can be any positive real number.

c) m can be any negative real number.

d) m can be any real number.

Answer: Omar can make 14 whole dumplings.

Step-by-step explanation: Make 2 3/4 an improper fraction. To do this, multiply 2 by the denominator, 4. From this, you get 8. Then add 8 to the numerator, which is 3, and you get 11. Keep the denominator and you'll have 11/4.

To divide fractions, you make 3/16 its reciprocal by basically flipping the fraction so that the numerator becomes the denominator and vise versa, making it 16/3. Then multiply 11/4 and 16/3. 11 x 16 is 176; 4 x 3 is 12. The result is 176/12. Simplify by dividing the numerator and denominator by 4. Your resulting answer should be 44/3. Simplify even further by simple division. Your final answer should be 14 2/3. Discard the 2/3 because Omar needs to make whole dumplings. So the answer is 14.

Final answer:

Omar can make 14 whole dumplings with 2 3/4 cups of dough when each dumpling requires 3/16 cups of dough.

Explanation:

The student's question asks how many whole dumplings Omar can make with 2 3/4 cups of dough if each dumpling uses 3/16 cups of dough.

Convert 2 3/4 cups to an improper fraction: 11/4 cups.

Divide the total cups of dough (11/4) by the amount needed for one dumpling (3/16) to find the number of dumplings Omar can make.

Perform the division: (11/4) \/ (3/16) = 11/4 \\* 16/3 = 44/3.

Omar can make 44/3 dumplings, which is 14 whole dumplings with some dough left over.

Omar can make 14 whole dumplings with 2 3/4 cups of dough when each dumpling uses 3/16 cups of dough.

Answer:

The Total number of car is 7 and The Total number of van is 5 .

Step-by-step explanation:

Given as :

The maximum capacity of car = 3 passengers

The maximum capacity of van = 8 passengers

Total number of vehicles = c + v = 12 vehicles

The maximum capacity of vehicles combination = 61 passengers

Let The Total number of car = c

Let The Total number of van = v

Now, According to question

c + v = 12            .........A

3 c + 8 v = 61            ............B

Now, Solving eq A and B

I.e (3 c + 8 v) - 3 × (c + v) = 61 - (3 × 12)

Or, (3 c - 3 c) + (8 v - 3 v) = 61 - 36

Or, 0 + 5 v = 25

∴ v = [tex]\dfrac{25}{5}[/tex]

i.e v = 5

So,The Total number of van = v = 5

Now Put the value of v into eq A

∵ c + v = 12    

So, c + 5 = 12

∴ c = 12 - 5

i.e c = 7

So,The Total number of car = c = 7

Hence,The Total number of car is 7 and The Total number of van is 5 . Answer
