Answer:

Step-by-step explanation:

Pat's Potato farm grew 490 pounds of potatoes. If Pat delivered 3/7 of the potatoes to the vegi stand, it means that the number of pounds of potatoes that pat delivered to the vergi store is

3/7 × 490 = 210 pounds

The owner of the vegi stand delivered 2/3 of the potatoes he bought to the grocery store. It means that the amount delivered to the grocery store is

2/3 × 210 = 140

If half of the delivered potatoes was packaged in bags of 5 pounds each, it means that the amount of potatoes packaged in the bags is 140/2 = 70 pounds.

The number of bags of 5 pounds that the grocery store packaged is

70/5 = 14 bags

Answer: 4^3 = 64

Step-by-step explanation:

Formula is [tex]a^c=b[/tex]

[tex]4^3=64[/tex]

Answer:

Answer:

300%

Step-by-step explanation:

Let the length of the carpet be L.

Let the width of the carpet be W.

The original area of the carpet is:

A = L * W = LW

The length and width are enlarged by 60%.

The new length is:

L + (L * 60/100) = L + 0.6L = 1.6L

The new width is:

W + (W * 60/100) = W + 0.6W = 1.6W

The length and width are then reduced by 25%.

The new length is:

1.6L + (1.6L * 25/100) = 1.6L + 0.4L = 2L

The new width is:

1.6W + (1.6W * 25/100) = 1.6W + 0.4W = 2W

The new area will be:

A = 2L * 2W = 4LW

To find the percentage increase in the area, we subtract the original area from the new area and divide by the original area:

4LW - LW = 3LW

% increase is:

[tex]\frac{3LW}{LW} * 100[/tex] = 300%

The area of the final item is 300% greater than the original item.

1 - 2 = -1

3 + 1 = 4

Option C should be the  correct answer.

Answer: 3rd option (x-2, y+1)

Answer:

-40

At -40, the value on both scales are the same.

-40 °C = -40 ° F

Step-by-step explanation:

Given that;

F = temperature in Fahrenheit

C = temperature in Celsius

And;

F=(9C+160)/5 .........1

For temperature to be the same on both scale;

Temperature in Fahrenheit mist be equal to the temperature in Celsius

F = C

Substituting F = C into the equation 1;

C = (9C +160)/5

Multiply both sides by 5

5C = (9C+160)

Collecting the like terms.

5C -9C = 160

-4C = 160

C = -160/4

C = -40

F = C = -40

At -40, the value on both scales are the same.

That means;

-40 °C = -40 ° F

Answer: 26.46cm

Step-by-step explanation:

The formula of a diagonal of a square is square root 2 a(a is not under the square root though)

So just substitute the a (area) with 350 and solve the equation.

Answer:

26.46cm

Step-by-step explanation:

Because you are dealing with a square, take the square root of the area and then use pythagoras theorem to calculate the diagonal.

Answer:

C

Step-by-step explanation:

Because in N(8)>2.N(5) there is 2 times N(5) in front of it. In the example N(g) means the numbers of students whose grade on the exam was g. so in this case N(8) means the numbers of students whose grade on the exam was 8 and N(5) means the numbers of students whose grade on the exam was 5. So when you turn this equation into words  it means The numbers of students whose grade was 8 is more than twice the number of students whose grade was 5.

Answer: 15

Step-by-step explanation:

6 percent of 250 is 15

15/250 = 6%.

Answer:

6% = 6/100 = 0.06

250 x 0.06 = 250 x 6 / 100

250 x 6 = 1500 / 100 = 15

Answer:

Mean: 58

Median: 59

Mode: 59

Step-by-step explanation:

34, 59, 59, 67, 71

Mean: 34 + 59 + 59 + 67 + 71 = 290/5 = 58

Median: 59

Mode: 59

Answer:

mean 58

median 59

mode 59

Step-by-step explanation:

67, 59, 34, 71, 59

The mean is the sum divided by the number of numbers

(67+ 59+ 34+ 71+ 59)/ 5 = 290/5 = 58

The median is the middle number  when the numbers are written from smallest to largest

34,   59, 59, 64, 71

The middle number is 59

The median is 59

The mode is the number that appears most often

The number 59 appears twice

59 is the mode

Answer:

Correct option: third one

f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily

Step-by-step explanation:

We can rewrite the equation using the model:

P = Po * (1 + r/n) ^ (nt)

Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the relation of the rate and the time (in our case, the rate is weekly and the time will be in days, so n = 7)

With P = f(x), Po = 86, r = 0.18 and t = x, we have:

f(x) = 86 * (1 + 0.18/7) ^ (7x)

f(x) = 86 * (1.02) ^ (7x)

So the daily rate of growth is approximately 2%

Correct option: third one

Answer:

16 + 6pi

Step-by-step explanation:

We have a square and 3 semicircles

The area of the square is

A = s^2 and the side length is 4

A = 4^2 = 16

The radius of the semi circle is 2

The area of a semicircle is

1/2 pi r^2

1/2 pi (2)^2 = 2pi

We have 3 of them

3 *2pi = 6pi

Add the areas together

16 + 6pi

Answer:

(6π + 16) cm²

Step-by-step explanation:

The composite shape can be cut into 4 shapes.

3 equal semi-circles and 1 square.

The square has a side length of 2 + 2 = 4cm.

The radius of the semi-circle is 2 cm.

The area of the square is:

4 × 4 = 16 cm²

The area of the semi-circle is:

2²π × 1/2

= (2π) cm²

There are 3 equal semi-circles, so multiply the area by 3.

2π × 3 = (6π) cm²

Add the areas of the 4 shapes.

16 cm² + (6π) cm²

= (6π + 16) cm²

The total area of the composite shape is (6π + 16) cm².

Answer:

1). Other line is, y = [tex]\frac{1}{3}x+5[/tex]

2). Solution of the system is (3, 6)

Step-by-step explanation:

From the table (1),

Let the equation of the line from the given table is,

y - y' = m(x - x')

Where m = slope of the line

(x', y') is a point lying on the line.

Choose two points from the table which lie on the line.

Let the points are (0, 5) and (3, 6)

Slope = m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

                 = [tex]\frac{5-6}{0-3}[/tex]

                 = [tex]\frac{1}{3}[/tex]

Therefore, equation of the will be,

y - 5 = [tex]\frac{1}{3}(x-0)[/tex]

y = [tex]\frac{1}{3}x+5[/tex] -------(1)

Let the other line from the table (2) is,

y - y" = m'(x - x")

Two points taken from this table are (0, 7) and (3, 6)

m' = [tex]\frac{7-6}{0-3}[/tex]

    = [tex]-\frac{1}{3}[/tex]

Equation of the line will be,

y - 7 = [tex]-\frac{1}{3}(x-0)[/tex]

y = [tex]-\frac{1}{3}x+7[/tex] -------(2)

Therefore, equation of the other line will be, y = [tex]\frac{1}{3}x+5[/tex]

By adding equations (1) and (2),

y + y = [tex]-\frac{1}{3}x+\frac{1}{3}x+5+7[/tex]

2y = 12

y = 6

From equation (1),

6 = [tex]\frac{1}{3}x+5[/tex]

[tex]\frac{1}{3}x=7-6[/tex]

x = 3

Therefore, solution of the system is (3, 6).

Answer:

The first line is 1/3x and 5. For the second line the answer is (3,6).

Answer:

The range is [-1, ∞).

Step-by-step explanation:

The  points where the graph of this function cut the x axis are at x = 2 and x = 4 ,  it opens upwards and has a minimum  value.

It has a minimum value  when x = (2 + 4) / 2 = 3.

When x = 3,  f(x) =  (3 - 4)(3 - 2) = -1.

So the range is all real values of x >= -1, or [-1, ∞)

Answer:

15: 1, 3, 5, 15

20x: 1, 2, 4, 5, 10, 20, x

Step-by-step explanation:

Answer:

Option B.

Step-by-step explanation:

If the value of function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersect x-axis at its zeroes.

From the given table it is clear that the value of function are

x  |  f(x) | Sign

2.0 |  2.8  | Positive  

2.5 |  1.1    | Positive

3.0 | –0.8 | Negative

3.5 | –1.2  | Negative

4.0 | –0.3 | Negative

4.5 |  0.7  | Positive

The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5.

It means, the graph of function must intersect x-axis in interval 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.

Therefore, the correct option is B.

Answer:

between 2.5 and 3.0 and between 4.0 and 4.5

Answer:

6/11

Step-by-step explanation:

Since there are 3 possible outcomes for the game (win,lose and draw) and the total probability for the three outcomes must be equal to 1.

Then;

The probability that the game will be a draw Pd = 1 - (probability that they will lose Pl + probability that they will win Pw)

Pd = 1 - (Pl + Pw) ........1

Given;

Pl = 3/11

Pw = 2/11

Substituting the values into equation 1;

Pd = 1 - (2/11 + 3/11)

Pd = 6/11

The probability that the game will be a draw Pd = 6/11

Answer:

Alex will be able to earn $60 for that 4-week period.

Step-by-step explanation:

It is given that

Income to Alex each week by babysitting and running errands:

$20.

To find the 4-week period earning, we need to add the value $20 for 4 times:

20 + 20 + 20 + 20 = $80

OR

In other words, 4 week period earning = 4 [tex]\times[/tex] 20 = $80

But, Alex was sick at one of the weekends, so $20 would be earned less.

Hence, during that 4-week period, total earning = $80 - $20

[tex]\Rightarrow[/tex] $60

So, Alex will be able to earn $60 for that 4-week period.
