Answer:

Let x = the number of pounds of oranges in the packet.

The equation: 11.20 = 1.25x + 4.95

11.20 = 1.25x+4.95

6.25 = 1.25x

x = 5

There are 5 pounds of oranges in the packet.

Let me know if this helps!

Answer:

The test statistic is 1.57.

Step-by-step explanation:

Our test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

A Seattle department store samples 89 items sold in January and found that 10 of the items were returned.

This means that [tex]n = 89, X = \frac{10}{89} = 0.1124[/tex]

7% of all merchandise sold in the United States gets returned.

This means that [tex]\mu = 0.07[/tex]

For a proportion, the standard deviation is [tex]\sigma = \sqrt{p(1-p)} = \sqrt{0.07*(1-0.07)} = 0.2551[/tex]

Test statistic:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \frac{0.1124 - 0.07}{\frac{0.2551}{\sqrt{89}}}[/tex]

[tex]t = 1.57[/tex]

The test statistic is 1.57.

Answer:

18 = number of players

Step-by-step explanation:

Giving the following information:

Members of a softball team raised $2039.50 to go to a tournament. They rented a bus for $1157.50 and budgeted $49 per player for meals.

To calculate the total number of players they can bring, we need to use the following formula:

Total amount of money= fixed cost + unitary variable cost*number of players

2,039.5= 1,157.5 + 49*number of players

882/49= number of players

18 = number of players

Answer:

49x+1157.50=2039.50

x=18

Answer:

FV= $2,041.29

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $1,500

Number of periods (n)= 7 years

Interest rate (i)= 4.5% = 0.045

To calculate the future value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 1,500*(1.045^7)

FV= $2,041.29

Answer: 400

Step-by-step explanation:

Area required by each couple = 72 inch by 72 inch

= 6 feet by 6 feet   [ 1 feet = 12 inches and [tex]72\text{ inches}=\dfrac{72}{12}\text{ feet}=6 \text{ feet}[/tex]]

= 36 square feet

Area in each studio = 30 ft by 30 ft = 900 square feet

Then, Area of 8 studios in Houstan = 8 x (900 feet) = 7200feet

Total couple the dance company can accommodate in the city of Houston for all of it's locations = [tex]\dfrac{7200}{36}=200[/tex]

Total people = 2 x (Total couples)= 2 x 200=400

Hence, a reasonable estimate for the total number of people the dance company can accommodate in the city of Houston for all of it's locations = 400

Answer:

i think its a but im not sure

Answer:

For the rectangular area, we will have a length L, and a width W, such that the two sides with measure L and one with measure W will be made with the material of $4 per ft, and the other side with measure W will be made with the material that costs $13 per ft.

Then the total cost will be:

C = (L + L + W)*$4 + W*$13.

And we know that the area is equal to 240 ft^2, then:

240ft^2 = L*W

To solve this, the first step is to isolate one of the variables in the second equation. I will isolate L:

L = (240ft^2)/W

Now we can replace this in the first equation to get:

C =  ( 2*(240ft^2)/W + W)*$4 + W*$13.

C = $4*480ft^2/W + W*$17

Now we want to find the minimum of this function, then we need to look at the zero of the first derivative of C:

C' = - ($4*480 ft^2)/W + W*$17 = 0

- ($4*480 ft^2) + $17*W^2 = 0

Let's solve this for W:

$17*W^2 =  ($4*480 ft^2)

W^2 = ($4*480 ft^2)/$17 = 112.94ft^2

W = √(112.94 ft^2) = 10.63 ft.

Then the width must be 10.64 ft, and the length can be obtained with the equation:

L*W = 240 ft^2

L*10.64 ft = 240 ft^2

L = (240 ft^2)/10.64ft = 22.56 ft

The width is 10.64 ft, and the length is 22.56 ft

Answer:

y=-6x+56

Step-by-step explanation:

The point-slope equation of a line is given as

y=mx+c   where m is slope and c is y-intercept of a line.

We are given m=-6 and a point (10,-4) which can be put into y=mx+c to find the only unknown c. Thus,

c=-4+6x10=56.

Now we can easily form the point-slope equation of the line

y=-6x+56.

Answer:

See solutions below

Step-by-step explanation:

1) Total amount of gallons = 14 gallons

If she uses up 0.75 gallons of gas each hour then;

1 hour = 0.75gallons

after driving 6 hours, amount of gallons used will be;

6 hours = x

Divide both expressions

1/6 = 0.75/x

x = 6 * 0.75

x = 4.5gallons

Amount of gas left = 14 - 4.5 = 9.5 gallons of gas

Hence 9.5 gallons of gas will be left after 6 hrs

Similarly;

1 hour = 0.75gallons

after driving t hours, amount of gallons used will be;

t hours = x

x = 0.75t

Amount of gas left after t hours = (14 - 0.75t) gallons of gas

2) We are to find the sum of -8x^2+3 and -9x^2+3x-3

-8x^2+3 + (-9x^2+3x-3)

= 8x^2+3 -9x^2+3x-3

Collect like terms

=  8x^2 -9x^2+3x + 3-3

= -x^2 + 3x

Hence the sum is -x²+3x

3) Expressing in standard form;

(-3x-5)(-x^2+x-5)

Expand

= 3x³-3x²+15x+5x²-5x+25

Collect like terms

= 3x³-3x²+5x²+15x-5x+25

= 3x³+2x² + 10x + 25

Hence the product in polynomial form is 3x³+2x² + 10x + 25

Answer:

0.19 = 19/100

19/100 = 19%

Step-by-step explanation:

take 0.19 x 100 = 19

that's where u get 19% and 19 over 100 from.

Answer:

0.19 = 19/100 = 19%

Step-by-step explanation:

1. Start with 0.19 (the given)

2. Read it out loud "19 hundredths"

3. Write down 19 out of 100 because that's what you said in the last step (if it were "0.3" you would write "3/10" because you read it as "three tenths"

4. Check if you can simplify. In this case you cannont

5. If the fraction is out of 100 (which in this case it is) simply write the numerator as the percent "19" is the numerator and it IS out of 100. You would write 19%

Answer:

A.) [tex]2x^2 + 13x - 7[/tex]

B.) [tex]3x^2 - 11x - 20[/tex]

C.) [tex]y^2 + 13y + 36[/tex]

D.) [tex]b^2 - 15b + 36[/tex]

Step-by-step explanation:

For all of these you want to multiply the first thingy (Ex. x) in the first parenthesis by the first in the second parenthesis (Ex. 2x) plus the first one in the first (Ex. x) times the second one in the second (Ex. -1) plus the second one in the first one (Ex. 7) times the first one in the second parenthesis (Ex. 2x)  plus the second one in the first parenthesis (Ex. 7) times the second one in the second (Ex. -1)

A.) (x + 7)(2x - 1) = (2x * x) + (-1 * x) + (7 * 2x) + (7 * -1) = 2x^2 -x + 14x - 7 = 2x^2 + 13x - 7

B.) (3x + 4)(x - 5) = (3x * x) + (3x * -5) + (4 * x) + (4 * -5) = 3x^2 - 15x + 4x - 20 = 3x^2 - 11x - 20

C.) (y + 9) (y + 4) = (y * y) + (4 * y) + (9 * y) + (9 * 4) = y^2 + 4y + 9y + 36 = y^2 + 13y + 36

D.) (b - 12)(b - 3) = (b * b) + (b * -3) + (-12 * b) + (-12 * -3) = b^2 - 3b - 12b + 36 = b^2 - 15b + 36
