Answer:

Gregory will catch up Efren after 26 minutes 40 seconds.

Explanation:

 Distance traveled = Speed x Time

 Speed of Efren = 4 mi/h

 Speed of Gregory = 8.5 mi/h

 Let the time of catch up be t hours.

 Time of journey of Efren before catch up = (t+0.5)hours, since he starts before half hour.

 Distance traveled by Efren = 4 x (t+0.5) miles

 Time of journey of Gregory before catch up = t hours.

 Distance traveled by Gregory = 8.5 x t miles

If they catch up the distance traveled by them is same, so equating both distances.

4 x (t+0.5) = 8.5 x t

4.5t = 2

t = 0.44 hours =26.67 minutes = 26 minutes 40 seconds.

So Gregory will catch up Efren after 26 minutes 40 seconds.

Gregory will catch up to Efren approximately at 9:56am.

To find out when Gregory will catch up to Efren, we need to set up an equation based on their speeds and the time they travel.

Calculate the head start distance: Efren leaves at 9am and walks at 4 miles per hour.

Determine their relative speed: Gregory runs at 8.5 miles per hour while Efren walks at 4 miles per hour.

Calculate the time for Gregory to catch up: We need to divide the head start distance by their relative speed.

Find the catch-up time: Gregory leaves at 9:30am, so add the catch-up time to this.

Therefore, Gregory will catch up to Efren at approximately 9:56am.

Answer: Option D. 1,778

Solution:

Standard brick:

Width: w=3.625 in

Height: h=2.25 in

Length: l=7.625 in

Volumen of one standard brick: v

v=w*h*l

v=(3.625 in)*(2.25 in)*(7.625 in)

v=62.19140625 in^3

Pallet of bricks:

Side: s=4 feet

s=(4 feet)*(12 in / 1 feet)→s=48 in

Volume of a pallet of bricks: V=s^3

V=(48 in)^3

V=110,592 in^3

Number of bricks could be in  a pallet: n

n=V/v

n=(110,592 in^3) / (62.19140625 in^3)

n=1,778.252119

n=1,778

To divide using synthetic division, arrange the polynomial in descending order, set up the synthetic division table, find the root of the divisor, perform the synthetic division, and read the coefficients of the quotient. In this case, the quotient is 2x^3 + x^2 + 4x + 3 with a remainder of -1.

To divide using synthetic division, you need to follow these steps:

In this case, the polynomial is 2x5 - x4 + 3x2 - x + 5, and the divisor is x - 1. Using synthetic division, we divide the coefficients:

The coefficients in the bottom row of the synthetic division table are 2, 1, 4, 3. Therefore, the quotient is 2x3 + x2 + 4x + 3, and the remainder is -1.

Remember that when we multiply fractions, we have to do it in a linear way, that is, numerators multiply each other, and denominators multiply each other. That means you CAN'T multiply a numerator with a denominator.

Answer: 93 grams Zinc

Step-by-step explanation:

3 Zinc : 13 Copper

x 31       x 31            

93 Zinc,     403 Copper

or

set up a proportion, cross multiply, and solve for the variable:

[tex]\frac{Zinc}{Copper}: \frac{3}{13} = \frac{x}{403}[/tex]

3(403) = 13(x)

[tex]\frac{3(403)}{13} = x[/tex]

3(31) = x

93 = x

The amount of zinc in the chemical is determined by using the given ratio of zinc to copper and applying it to the given amount of copper. Step-by-step calculations reveal the quantity of zinc to be 93 grams.

The question is asking for the amount of zinc in a chemical where the ratio of zinc to copper is 3:13. To find out this, we need to solve for zinc in terms of the given amount of copper.

First, understand that the ratio means for every 3 grams of zinc, there are 13 grams of copper. Now, simply set up a proportion where 3/13 = x/403. Here x is the amount of zinc in grams we are trying to find. 3/13 is the zinc to copper ratio and 403 is the known amount of copper in grams.

When you cross multiply and solve for x, you'll find that x = 3 * 403 / 13 = 93 grams. This means, if there are 403 grams of copper, then there must be "93 grams of zinc".

Answer:

Unfortunately, your answer is not right.

Step-by-step explanation:

The functions whose graphs do not have asymptotes are the power and the root.

The power function has no asymptote, its domain and rank are all the real.

To verify that the power function does not have an asymptote, let us make the following analysis:

The function [tex]y = x ^ n[/tex] , when x approaches infinity, where does y tend? Of course it tends to infinity as well, therefore it has no horizontal asymptotes (and neither vertical nor oblique)

With respect to the function [tex]y= \frac{1}{x}[/tex] we ​​can verify that if it has asymptote horizontal in y = 0. Since when x approaches infinity the function is closer to the value 0.

For example: 1/2 = 0.5;   1/1000 = 0.001;    1/100000 = 0.00001 and so on. As "x" grows "y" approaches zero

Also, when x approaches 0, the function approaches infinity, in other words, when x tends to 0 y tends to infinity. For example: 1 / 0.5 = 2; 1 / 0.1 = 10; 1 / 0.01 = 100 and so on. This means that the function also has an asymptote at x = 0

Answer:

y = 44+22m

Step-by-step explanation:

Given that a taxi has a minimum charge of 44 dollar upto 1 mile and adds 22 for every additional 1 mile.

If a person travels 1 miles his charges are 44 dollar

If he travels >1 miles charges are 4 dollar +22(extra miles )

Let y be the charges and m be the no of miles.

Then the equation for y in terms of m would be

y =44+22m

is the correct answer.

First of all, we need to do the expression in parenthesis first.

(4% - 2.25%) = 1.75%

Now, we convert the percent into an integer.

1.75% = 0.0175

Then, we multiply 44.5 by 0.0175

and we get 0.77875.

We have to round the number to the nearest cent.

0.77875 is roughly 0.78

So the answer is $0.78.

Domain ={0,infinity)

Range = (-infinity, 4]

Step-by-step explanation:

Given a graph with curve which has y intercept 4.

It passes x axis at 4 and extends fully

The domain is the set of values x can take

In the graph horizontal axis is x axis.

Hence from the graph we see that x can take values from 4 including 4 upto infinity.

Hence domain is x>=4

For range, we consider the values of y as per graph.

WE find that y is not taking values >4

Hence Range = (-infty, 4]

Answer:

[tex]Domain=[0,\infty)[/tex]

[tex]Range=(-\infty,4][/tex]

Step-by-step explanation:

We need to find the domain and range of the function.

Domain : It is the set of input values or x values. In a graph, domain of the function represented by the x-axis.

Range : It is the set of output values or y values. In a graph, range of the function represented by the y-axis.

From the given graph it is clear that it is defined for [tex]0\le x<\infty[/tex] and [tex]-\infty <y\le 4[/tex].

We have closed circle at (0,4). It means, 0 is included in the domain and 4 is included in the range.

[tex]Domain=[0,\infty)[/tex]

[tex]Range=(-\infty,4][/tex]

Therefore, [tex]Domain=[0,\infty)[/tex] and [tex]Range=(-\infty,4][/tex].

Answer:

14.64 cm

Step-by-step explanation:

The circumference of a planting pot = 92 cm

To find the measurement of the plant which is planted directly planted in the middle of the pot, we need to find the radius of the planting pot.

We know that the formula of the circumference of a circle is:

Circumference = [tex]2\pi r[/tex]

Therefore, putting the value of the circumference in the formula to get:

Hello!

When multiply binomials together, we should use the FOIL method.

The FOIL method is an acronym for First, Outer, Inner, and Last.

First, let's set up the expression.

(7x - 1)(3x - 2)

Now, we can multiply in accordance with the FOIL method.

First: 7x · 3x = 21x²

Outer: 7x · -2 = -14x

Inner: -1 · 3x = -3x

Last: -1 · -2 = 2

Now, we simplify the inner terms.

21x² - 14x - 3x + 2

21x² - 17x + 2

Therefore, the area of the rectangle is 21x² - 17x + 2.

The area of the rectangle is (21x² - 17x + 2) units².

A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.

Given the length of the rectangle is (7x-1) units, while its breadth is (3x-2) units. Therefore, the area of the rectangle is,

Area of rectangle = (7x-1) units × (3x-2) units

= 21x² - 14x - 3x + 2

= 21x² - 17x + 2 units²

Hence, the area of the rectangle is (21x² - 17x + 2) units².
