Given equation:

Now, let's solve the equation:

Their rate was 85 toys per day.

Answer: (5 × 8) - (5 × 1)

Step-by-step explanation:

When you use the distributive property, you essentially distribute a number to terms it is being multiplied by in order to make the calculation process easier.

When you use the distributive property, you distribute the number outside a multiplication statement to the numbers inside. In this case, 5 is the number outside, and 8 and 1 are the numbers inside.

When you distribute the number 5 to the eight, you are left with (5 × 8). However, you must still include 1, the other number in the parentheses, to finish the equation.

With 1, you go through the same process as you did before. You distribute the number 5 to the 1 and are left with (5 × 1). However, in the original equation, you are subtracting the 8 by the 1, so you must account for the subtraction sign.

You essentially subtract the number you get from (5 × 8) by the number you get from (5 × 1). Therefore, your answer is (5 × 8) - (5 × 1).

In accordance with the exponential model, the current forest area is equal to 2801.149 square kilometers after six years.  

According with statement, the forest area decreases exponentially in time. Then, the exponential model is defined by following model:

n(x) = n' · (1 - r)ˣ

Where:

If we know that n' = 4400 km², r = 0.0725 and x = 6 yr, then the current forest area is:

n(6) = 4400 · (1 - 0.0725)⁶

n(6) = 2801.149

This question is not complete, the complete question is;

A newsletter publisher believes that 68% of their readers own a Rolls Royce. Is there sufficient evidence at the 0.05 level to refute the publisher's claim

State the null and alternative hypotheses for the above scenario.

Answer:

Null Hypothesis            H₀ : P = 0.68  

Alternative Hypothesis H₁ : P ≠ 0.68  

Step-by-step explanation:

Given that;

A newsletter publisher believes that 68% of their readers own a Rolls Royce

so

proportion of readers = 68% = 68/100 = 0.68

Level of significance ∝ = 0.05

Now the Null and Alternative Hypothesis for this case will be;

Null Hypothesis            H₀ : P = 0.68  

Alternative Hypothesis H₁ : P ≠ 0.68

How to find?

The composition r x-axis ° T(7,5) first reflects the quadrilateral MATH about the x-axis and then translates it 7 units to the right and 5 units up.

To find the image of M(-6,-3) after reflection about the x-axis, we flip the sign of the y-coordinate to get M'(-6,3). Then, we translate M' 7 units to the right and 5 units up to get the coordinates of M":

M" = T(7,5) ∘ M' = (7 + (-6), 5 + 3) = (1, 8)

Similarly, we can find the coordinates of A", T", and H":

A' = (-1, 3) → A" = T(7,5) ∘ R(x-axis) ∘ A' = (7 + (-1), 5 - 3) = (6, 2)

T' = (-2, 1) → T" = T(7,5) ∘ R(x-axis) ∘ T' = (7 + (-2), 5 - 1) = (5, 4)

H' = (-4, 1) → H" = T(7,5) ∘ R(x-axis) ∘ H' = (7 + (-4), 5 - 1) = (3, 4)

Therefore, the coordinates of M"A"T"H" are M"(1,8), A"(6,2), T"(5,4), and H"(3,4).

\( \displaystyle \angle3 = {90}^{ \circ} \)

Step-by-step explanation:

we are given two angles

we are want to figure out the missing angle

remember,

Straight line theorem

so we acquire

\( \displaystyle \angle3 + \angle4 = {180}^{ \circ} \)

substitute the value of the given angle:

\( \displaystyle \angle3 + {90}^{ \circ} = {180}^{ \circ} \)

cancel 90° from both sides:

\( \displaystyle \angle3 = {90}^{ \circ} \)

The sixth-graders at Tisha's faculty were given to choose among a field journey to a museum and a area journey to a manufacturing unit.

To calculate the percentage of 6th-graders the one picked the museum as their area journey desire, we need to divide the range of students who chose the museum with the aid of the entire number of sixth-graders, in addition to then multiply by means of 100.

Number of students who chose the museum = 39

Total number of sixth-graders = 52

Percentage of sixth-graders who picked the museum = (Number of students who chose the museum / Total number of sixth-graders) * 100

Percentage = (39 / 52) * 100

Percentage ≈ 0.75 * 100

Percentage ≈ 75

Therefore, approximately 75% of the sixth-graders picked the museum as their field trip choice.

Answer:

40 girls

Step-by-step explanation:

Set up a proportion where x is the number of girls in band class:

\(\frac{3}{5}\) = \(\frac{24}{x}\)

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.

Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

\(\frac{3}{5} = \frac{24}{x}\)

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.

The lines CA and CD are tangents to the circle O, hence; EA = 4, AB = 15, m∠ABO = 90°, m∠ODC = 90°, and m∠EAB = 30°.

The tangent to a circle theorem states that a line is tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency

If OB = 6 and AB = 8, then;

OA = √(8² + 6²) {by Pythagoras rule}

OA = √100

OA = 10

EA = OA - OE(radius)

EA = 10 - 6 = 4

If DE = 16 and EA = 9, then;

OA = (diameter/2) + EA

OA = 8 + 9 = 17

AB = √(17² - 8²)

AB = √225

AB = 15

OB is perpendicular to line CA tangent to the circle so m∠ABO = 90°

OD is perpendicular to the line CD tangent to the circle so m∠ODC = 90°

If m∠DOB = 120° then;

120° = m∠ABO + m∠EAB {exterior angle of a triangle is equal to the two opposite interior angles}

m∠EAB = 120° - 90°

m∠EAB = 30°

In conclusion, for the lines tangent to the circle, we have that;

EA = 4, AB = 15, m∠ABO = 90°, m∠ODC = 90°, and m∠EAB = 30°

The sum of angles in a triangle is always 180 degrees. Therefore, the angle C measures 60 degrees.

In triangle ABC, we know that angle A measures 75 degrees, and angle B measures 45 degrees.

To find the measure of angle C, we can use the fact that the sum of the angles in a triangle is 180 degrees:

Angle A + Angle B + Angle C = 180

Substituting the values we know:

75 + 45 + Angle C = 180

Simplifying:

120 + Angle C = 180

Subtracting 120 from both sides:

Angle C = 60

Therefore, angle C measures 60 degrees.

The solutions to the equation 1x² - 16x = 20 are x = 8 + 2√21 and x = 8 - 2√21.

To solve the quadratic equation 1x² - 16x = 20, we need to rearrange it into the standard form ax² + bx + c = 0. Let's simplify the equation step by step:

1x² - 16x = 20

First, move all terms to one side of the equation:

1x² - 16x - 20 = 0

Now we have a quadratic equation in the standard form. To solve it, we can use factoring, completing the square, or the quadratic formula. In this case, factoring may not be straightforward, so let's use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

For our equation, a = 1, b = -16, and c = -20. Substituting these values into the quadratic formula:

x = (-(-16) ± √((-16)² - 4(1)(-20))) / (2(1))

Simplifying further:

x = (16 ± √(256 + 80)) / 2

x = (16 ± √336) / 2

x = (16 ± √(16 * 21)) / 2

x = (16 ± 4√21) / 2

Simplifying:

x = 8 ± 2√21

In geometry, a great circle is a circle on a sphere whose center is also the sphere's center.

The largest circle that can be drawn on a sphere is called a great circle. It divides the sphere into two equal halves, and its center coincides with the center of the sphere. A small circle is any circle that is not a great circle.

Great circles are important in navigation and are used to determine the shortest distance between two points on the surface of a sphere. The equator and all longitude lines are examples of great circles. In contrast, small circles are tilted with respect to the equator and do not divide the sphere into two equal halves.

There were 5 1/4 bags of popcorn left after eating 4 bags.

To find out how much popcorn was left after eating 4 bags, we need to subtract the amount eaten from the total amount Brianna made.

Brianna made 9 1/4 bags of popcorn, which can be represented as a mixed number. To perform calculations, let's convert it to an improper fraction:

9 1/4 = (4 * 9 + 1) / 4 = 37/4

Now, let's subtract the 4 bags eaten from the total:

37/4 - 4

To subtract fractions, we need a common denominator. The common denominator of 4 and 1 is 4. Therefore, we can rewrite the expression as:

37/4 - 4/1

Now, let's find a common denominator and subtract the fractions:

37/4 - 16/4 = (37 - 16) / 4 = 21/4

The result is 21/4, which is an improper fraction. Let's convert it back to a mixed number:
