The sum of two numbers, one of 7 times as large as the other, is 48. Find the two numbers.

Answers

Answer 1
1 is 7 times larger than the other one. Sum is 48 so:

x+7x = 48
8x= 48
x= 6

Therefore 7x= 42

2 numbers are 42 and 6

Answer:

2x sqrt(3)

Step-by-step explanation:

f(x) = 4x sqrt(3x+3) =4x sqrt(3  (x+1)) = 4x sqrt(3 ) * sqrt (x+1)

g(x) = 2 sqrt(x+1)

f(x) / g(x) = 4x sqrt(3 ) * sqrt (x+1)/ 2 sqrt(x+1)

     Canceling like terms

              = 4x sqrt(3) / 2

HURRY I HAVE 30 MINUTES What are the x and y coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4?

Answers

Answer:

(-7, -1)

Step-by-step explanation:

The ratio is 1:4, the total is 1 + 5 = 5, so the partition is at 1/5 of the total length.

x2 - x1 = 25 - (-15) = 40

1/5 * 40 = 8

-15 + 8 = -7

x = -7

y2 - y1 = 15 - (-5) = 20

1/5 * 20 = 4

-5 + 4 = -1

y = -1

Answer: (-7, 1)

Simplify: (3x2 − 8xy + y2) − (7x2 − 4xy − 5y2)

Answers

Answer:

[tex]-4x^{2} -4xy+6y^{2}[/tex]

Step-by-step explanation:

(3x2 − 8xy + y2) − (7x2 − 4xy − 5y2)

First, we remove the parenthesses. We can just remove the first parnthesses because there isn't any sign before them. When removing the second ones, we will change the sign of every term in it. It becomes:

[tex]3x^{2} -8xy+y^{2} -7x^{2} +4xy+5y^{2}[/tex]

Now we will combine the like terms. That means that we will subtract 7x2 from 3x2, add 4x to -8x etc.

[tex]-4x^{2} -4xy+6y^{2}[/tex]

The oblique pyramid has a square base with an edge length of 5 cm. The height of the pyramid is 7 cm. What is the volume of the pyramid?

Answers

Answer:

875 cm^3

Step-by-step explanation:

Here, we want to calculate the volume of the pyramid.

To do this, we need to calculate the area of the base and then multiply this by the height of the pyramid in question

Mathematically since the base is a square, formula for the base area would be ;

L^2 = 5^2 = 125 cm ^2

Now

using the height to get the volume , we have 125 * 7 = 875 cm^3

Answer:

58 1/3 cm³

Step-by-step explanation:

V = 5² * 7 / 3

V = 25 * 7 / 3

V = 58 cm³

Solve for x. Write both solutions, separated by a comma. 8x^2+7x-1=0

Answers

Answer:

x = 1/8 , - 1

Step-by-step explanation:

8x² + 7x - 1 = 0

Rewrite 7x as a difference

That's

8x² + 8x - x - 1 = 0

Factorize

8x( x + 1) - ( x + 1) = 0

(8x - 1)( x + 1) = 0

8x - 1 = 0 x + 1 =0

8x = 1 x = - 1

x = 1/8

The solutions are

Restando los polinomios

(4x + 9) - (5x - 8) = - x + 17

-5x +8 + 4x + 9 = -x + 17

-x + 17 = -x + 17

(x2 - 4x + 7) - (2x2 + 6x - 8) = -20x2-13x-72

First we will multiply the polynomials  with the brackets

Answers

Answer:

Option C.

Step-by-step explanation:

In a linear function, the change in y-values with respect to x-values is constant.

We need to find table from the given tables which represents a non-linear function.

In option A, x is increasing by 1 unit and y is decreasing by 1 unit. So, rate of change is constant.

In option B, x is increasing by 1 unit and y is decreasing by 1 unit. So, rate of change is constant.

In option C, x is increasing by 1 unit but y is not decreasing by same units. So, rate of change is not constant.

In option D, x is increasing by 1 unit and y is increasing by 1 unit. So, rate of change is constant.

Only in option C, the rate of change is not constant. So, it represents a non-linear function.

Therefore, the correct option is C.

Sam has some red and yellow cubes. She has 20 cubes in total. She has 8 more yellow cubes than red ones. How many red cubes does she have?Sam has some red and yellow cubes. She has 20 cubes in total. She has 8 more yellow cubes than red ones. How many red cubes does she have?

Answers

Answer:

6

Step-by-step explanation:

Let's call the number of red cubes that Sam has r, and the number of yellow cubes that she has y.

Since the sum of the number of cubes is 20:

r+y=20

Since she has 8 more yellow cubes than red ones:

y=r+8

You can now plug this back into the first equation:

r+(r+8)=20

2r+8=20

2r=12

r=6

Therefore, Sam has 6 red cubes. Hope this helps!

Hope this helps!

Answer:

6 red cubes

Step-by-step explanation:

Let statements: let y be the number of yellow cubes, and let r be the number of red cubes.

r+y=20

r+8=y

r+(r+8)=20

2r+8=20

2r=12

r=6

The pro shop at the Live Oak Country Club ordered two brands of golf balls. Par One balls cost $2.00 each and the Pro Sport balls cost $0.90 each. The total cost of Par One balls exceeded the total cost of the Pro Sport balls by $660.00. If an equal number of each brand was ordered, how many dozens of each brand were ordered?

Answers

Answer:

If an equal number of each brand was ordered, how many dozens of each brand were ordered?

50 dozens of each brand

Step-by-step explanation:

in order to determine the number of balls purchased, we must first determine the difference in price between them = $2 - $0.90 = $1.10

since the total difference in price was $660 and an equal number of balls were purchased, then the number of balls purchased = $660 / $1.10 = 600 balls

to determine the number of dozens purchased of each brand we just divide 600 by 12 = 50 dozens

A city park commission received a donation of playground equipment from a parents' organization. The area of the playground needs to be 256 square yards for the children to use it safely. The playground will be rectangular. The city will pay to have soft pavement made of recycled tires installed in the playground. In the first plan, one side 8 yards longer than the other side. Which equations model the possible dimensions of the playground? x( x + 8) = 256 ( x2) - 8 = 256 x2- 8 x - 256 = 0 ( x + 4)( x - 4) = 256 x( x - 8) = 256

Answers

Answer:

x(x+8) = 256

Step-by-step explanation:

hello

one side is x

the other one is 8 yards longer, so it is x + 8

so the surface is x(x+8) = 256

hope this helps

Answer:

x(x + 8) = 256

Step-by-step explanation:

The area of a rectangle can be calculated by doing length times width.

One side is 8 yards longer than the other. Let one side be represented by x. So, another side would be x + 8.

x * (x + 8) = 256

x(x + 8) = 256

x^2 + 8x = 256

Stu Dent received scores of 85, 78, and 81 on his first 3 exams in Algebra 1. What is the lowest score does Stu has to get on his 4th exam, so his test average would be at least an 84?

Answers

Answer:

92

Step-by-step explanation:

Given

Scores: 85, 78, 81

Required

Determine the least score in 4th subject is average must be at least 84

To solve this, we'll make use of Mean formula.

Mean = Sum of observations/Number of observations

We have that; Average = 84

Number of subjects = 4

Let the 4th subject be represented by F;

So, the sum of the four Subjects is:

Sum = 85 + 78 + 81 + F

Sum = 244 + F

Substitute these values in the above formula.

84 = ¼(244 + F)

Multiply both sides by 4

4 * 84 = 4 * ¼(244 + F)

336 = 244 + F

Subtract 244 from both sides

336 - 244 = 244 - 244 + F

92 = F

F = 92

To have an average of at least 84, Su's score must be atleast 92

For the following exercises, use this scenario: A biologist recorded a count of 360 bacteria present in a culture after 5 minutes and 1000 bacteria present after 20 minutes. Rounding to six significant digits, write an exponential equation representing this situation. To the nearest minute, how long did it take the population to double a ski resort has 3 pricing options on his 20 $ for a ski lesson, or 60 $ for a lift pass, or 70 $ for both lift and lesson. 50 people bought exactly one of the options, and if 42 lift tickets were sold and 23 lessons, what is the mean/average amount they paid in dollars and cents am giving all my points need answer now Help me fill in the blanks With which statement about metaphysics would Heraclitus have been most likely to agree? Read the excerpts from Ovid's "Pyramus and Thisbe" and Shakespeare's Romeo and Juliet. "Pyramus and Thisbe" They owed their first encounters to their living close beside each otherbut with time, love grows. Theirs didindeed they wanted to be wed, but marriage was forbidden by their parents; yet there's one thing that parents can't prevent: the flame of love that burned in both of them.

From forth the fatal loins of these two foes A pair of star-cross'd lovers take their life; Whose misadventured piteous overthrows Do with their death bury their parents' strife. What statement best describes the relationship between these works?

How many roots of the polynomial lie between x=-4 and x=3 how to do this question plz The dimensions of a closed rectangular box are measured as 96 cm, 58 cm, and 48 cm, respectively, with a possible error of 0.2 cm in each dimension. Use differentials to estimate the maximum error in calculating the surface area of the box.
