Answers

Answer 1
Answer:

Answer:

Adding the numbers up gives:

2 + 2 + 3 + 5 + 5 + 7 + 8 = 32

There are 7 values, so you divide

the total by 7:    32 ÷ 7 = 4.57...

So the mean is 4.57 (2 d.p.)

What is the volume of the right prism? A.
23 cm3

B.
46 cm3

C.
192.5 cm3

D.
385 cm3

Answers

The answer to this is C.

To figure out the volume of a prism use LWH/2.

Think of it as a 2D triangle when finding the area you times by width and height and then divide by two. In this case the shape is 3D, but it is still the same concept, except that you are also timing it by the length also.

Hope that helps : )

(x+2) is one of the factors of the polynomial x³+13x²+32x+20. Find its remaining factors.A little help....​

Answers

Answer:

x^2+11x+10

or

(x+1)(x+10) since you can factor x^2+11x+10

Step-by-step explanation:

Let's do synthetic division.

We are dividing by x+2, so -2 will be on the outside. Like this:

-2 |         1          13          32         20

   |                     -2        -22         -20

   |___________________________

             1          11           10            0

The remainder is 0, so (x+2) is indeed a factor of x^3+13x^2+32x+20.

The other factor we found by doing this is (x^2+11x+10).

You can find more factors by factoring x^2+11x+10.

Two numbers that multiply to be 10 and add to be 11 is 10 and 1 so the factored form of x^2+11x+10 is (x+10)(x+1).

Malcolm is downloading a file that is 50.4 Mb. his internet connection has a download speed of 1.2 mb per second.

Answers

the equation is 1.2t=50.2 And the solution is 42

Answer:

42 seconds

Step-by-step explanation:

The equation is 1.2t = 50.4

how to solve:

1.2t = 50.4

first, divide from both sides

1.2t/1.2 = 50.4/1.2

the 1.2t/1.2 cancels out.

so we have 50.4/1.2 left

when you do the math you get the answer 42!

so 42 seconds.

a farm raises cows and chickens. the farmer has a total of 42 animals. one day he counts the legs of all animals of his animals and realizes he has a total of 114. how many cows does the farmer have? how many chickens?

Answers

Let's call cows x, and chickens as y.

Cows have 4 legs
Chickens have 2 legs.

Let's make two equations from the information they gave us!

x + y = 42
4x + 2y = 114

Now, let's multiply the first equation by 4.

4x + 4y = 168
4x + 2y = 114

Now, subtract the second equation from the first one.

4x - 4x + 4y - 2y = 168 - 114

4y - 2y = 168 - 114

2y = 54

y = 27

Now, plug y = 27 into either equation and solve for x.

x + y = 42

x + 27 = 42

x = 42 - 27

x = 15



There are 15 cows and 27 chickens.

A convenience store sells two brands of orange juice. Brand A contains 8 fluid ounces and costs $1.28. Brand B contains 12 fluid ounces and costs $1.68. What is the difference in cost, in dollars, per fluid ounce between the two brands of juice?

Answers

Answer:

The difference between both brands is $0,02

Step-by-step explanation:

To compare both cost per ounce ,  we must get this cost for each brand. We get it dividing the price by the content.

Brand A contains 8 fluid ounces and costs $1.28.

CostA=$1.28/8 ounces

CostA=$0,16 per ounce

Brand B contains 12 fluid ounces and costs $1.68.

CostB=$1.68/12

CostB=$0,14 per ounce

The difference between both brands is Cost A- Cost B

CostA-CostB=$0,16 per ounce -$0,14 per ounce

Dif=$0,02
Brand A: 8(fl oz):$1:28
Brand B: 12:1.68
1)divide each side of the ratio
8:1.28 = 1:0.16
divide 8 by 8, and 1.28 by 8.
12: 1.68 = 1:0.14
divide each side by 12.
so, for brand A, for every one fluid oz it costs $0.16. for brand B, for every one fluid oz, it costs $0.14.
0.16-0.14= 0.02
$0.02 per fluid oz
