Answer: [tex]\frac{7}{16}hour[/tex]

Step-by-step explanation:

You know that the total time was: 7/8 hour

You also know that they spent 1/2 of the time at the beach.

Therefore, to calculate the time  Zach and his dog spend at the beach (which you can call x) , you must multiply both fractions (7/8 and 1/2).

Then, you obtain the following result:

[tex]x=\frac{7}{8}hour*\frac{1}{2}\\\\x=\frac{7}{16}hour[/tex]

Zach and his dog spent 7/16 of an hour at the beach. This was calculated by multiplying the total walking time of 7/8 of an hour by 1/2, which represents the proportion of the total time spent at the beach.

The question is asking for the amount of time that Zach and his dog spent at the beach. We know that they spent 1/2 of their total walking time, which was 7/8 hour, at the beach. To find this, we simply need to multiply those two fractions together. Multiply the numerators (top numbers) together to get the numerator of the product, and multiply the denominators (bottom numbers) together to get the denominator of the product. 1 * 7 equals 7, and 2 * 8 equals 16, so the product is 7/16 of an hour. This is the amount of time they spent at the beach.

Answer:

x = 2

Step-by-step explanation:

The product of the external part times the entire secant of one secant is equal to the external part times the entire secant of the other secant, that is

(x + 4)(x + 5) = (x + 1)(x + 12) ← distribute factors on both sides

x² + 9x + 20 = x² + 13x + 12 ( subtract x² from both sides )

9x + 20 = 13x + 12 ( subtract 13x from both sides )

- 4x + 20 = 12 ( subtract 20 from both sides )

- 4x = - 8 ( divide both sides by - 4 )

212.5

Step-by-step explanation:

10=85

212.5=25

Gavin can drive 8.5 miles with 1 gallon of gas. Therefore, he can drive 212.5 miles with 25 gallons of gas.

The question asks how many miles Gavin can drive on 25 gallons of gas, given that he has driven 85 miles on 10 gallons of gas. This requires the use of proportions to calculate. First, you find out how many miles Gavin can drive on 1 gallon of gas, which is 85 miles / 10 gallons = 8.5 miles/gallon. Then, using this value, we can multiply it by 25 gallons to get the total miles Gavin can drive on 25 gallons, which is 8.5 miles/gallon * 25 gallons = 212.5 miles. Therefore, Gavin can drive 212.5 miles on 25 gallons of gas.

Answer:

95 percent

Step-by-step explanation:

The empirical rule states that approximately 95% of observations will fall within 2 standard deviations of the mean if the population is approximately symmetrical(normal) in distribution.

The interval from 33 to 65 falls within 2 standard deviations of the mean;

49-2(8) = 33

49+2(8) = 65

Thus, 95 percent  of data will fall within the interval from 33 to 65

Since we are given a quadratic function, we need to write it using the standard form of quadratic function (parabola).

The given function is:

[tex]f(t)=3-2t.2t=+t[/tex]

The standard form of a parabola is:

[tex]f(t)=a^{2}+bx+c[/tex]

Area of the rectangle= L× W =42cm²

(2x-5) × x =42

x(2x-5)=42

2x²-5x-42=0

The area of the pattern is calculated by finding the area of the circle, semicircles, and quarter-circles separately and then adding them together. The area of the pattern is approximately 1005.31 cm^2.

To find the area of the pattern, we need to calculate the area of the circle, semicircles, and quarter-circles separately. The area of a circle is found using the formula A = πr^2, where r is the radius. So, the area of the circle is A = π(8)^2 = 64π cm^2. The area of a semicircle is half the area of a circle, so it is 32π cm^2. The area of a quarter-circle is a quarter of the area of a circle, which is 16π cm^2. To find the total area of the pattern, we add the areas of the circle, semicircles, and quarter-circles: 64π + 4(32π) + 8(16π) = 64π + 128π + 128π = 320π cm^2. Rounding to the nearest hundredth, the total area of the pattern is approximately 1005.31 cm^2.

Finding the areas of the circles, semicircles, and quarter-circles separately and combining them together yields the pattern's overall area. The pattern's estimated area is 1005.31 cm^2.

To determine the area of the pattern, individual areas of the circle, semicircles, and quarter-circles are computed separately.

Utilizing the formula

A = πr^2

for a circle with a radius (r) of 8 cm, the circle's area is 64π cm^2.

The semicircles, constituting half the circle's area, total 32π cm^2 each.

Quarter-circles, representing a quarter of the circle's area, contribute 16π cm^2 each.

Combining these, the pattern's total area is calculated as 64π + 4(32π) + 8(16π) = 320π cm^2.

Rounded to the nearest hundredth, the total area is approximately 1005.31 cm^2.

This comprehensive approach ensures the accurate summation of all constituent shapes within the intricate pattern.

both pair of opposite angles inscribed in the quadrilateral are supplementary to each other. By supplementary to each other we mean that their sum is equal to 180°.

In this case we have opposite interior angles supplementary to each other hence we can circumscribe a circle around it. Such Quadrilateral are called cyclic quadrilateral.

Answer:

C. 4%

Step-by-step explanation:

Answer:

B) x = 1

C) x = 4

Step-by-step explanation:

Given:

f(x) = 2x

g(x) = 2^x

We have to find at what value of x, the above two functions are equal in value.

Now we have to check with the each options.

When x = 0, f(0) = 2(0) = 0 ; g(0) = 2^0 = 1 [Anything power 0, is 1]

When x = 1, f(1) = 2(1) = 2 ; g(1) = 2^1 = 2.

when x = 2, f(2) = 2(2) = 4; g(2) = 2^2 = 4

when x = 3, f(3) = 2(3) = 6, g(3) = 2^3 = 8

when x = 4, f(4) = 2(4) = 8, g(4) = 2^4 = 16

The two functions are equal in value when x = 1 and x = 2.

Final answer:

The value(s) of x for which the equation f(x) = 2x and g(x) = 2ˣ are equal are x = 1 and x = 2, as those are the points where the two functions have the same value.

Explanation:

The student seems to be asking for which value(s) of x the equations f(x) = 2x and g(x) = 2ˣ are equal. To find the solution, we need to identify the point where the two functions intersect, by setting them equal to each other and solving for x.

So we set up the equation 2x = 2ˣ and look for solutions. At first glance, it seems there are two obvious solutions:

When x = 1, f(x) = 2 x 1 = 2 and g(x) = 2¹ = 2, so the statement f(x) = g(x) is true.

When x = 0, f(x) = 2 x 0 = 0 and g(x) = 2⁰ = 1, so the statement f(x) = g(x) is not true.

Testing the other provided options similarly, you'll find that:

For x = 2, f(x) = 4 and g(x) = 4, hence f(x) = g(x) is true.

For x = 3, f(x) = 6 and g(x) = 8, hence f(x) = g(x) is not true.

For x = 4, f(x) = 8 and g(x) = 16, hence f(x) = g(x) is not true.

The correct answers are x = 1 and x = 2, where the equation f(x) = g(x) holds true.

x2=-b-√D/2a=4-14/6=-10/6=-5/3

Answer:

x = 3

Step-by-step explanation:

Using Pythagoras' theorem on the right triangle, then

(2x - 1)² = 4² + x² ← expand parenthesis on the left side and simplify

4x² - 4x + 1 = 16 + x² ( subtract 16 + x² from both sides )

3x² - 4x - 15 = 0 ← in standard form

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 × - 15 = - 45 and sum = - 4

The factors are - 9 and + 5

Use these factors to split the x- term

3x² - 9x + 5x - 15 = 0 ( factor the first/second and third/fourth terms )

3x(x - 3) + 5(x - 3) ← factor out (x - 3)

(x - 3)(3x + 5) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - [tex]\frac{5}{3}[/tex]

The measure of one interior angle of a 42 sided regular polygon is given by A = 171.428°

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the interior angle of the polygon be represented as A

Now , let the number of sides of the polygon be n = 42 sides

So , Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

On simplifying , we get

42θ = 180 ( 42 - 2 )

42θ = 180 ( 40 )

Divide by 42 on both sides , we get

A = 180 ( 40 ) / 42

A = 171.428°

Therefore , the value of A is 171.428°

Hence , the measure of one angle is  171.428°
