Answer:

12

Step-by-step explanation:

0 + 12 = 12

Answer:

12

Step-by-step explanation:

the 2 numbers 12 units away from 0 are 12 and -12

since it's to the right of 0, it's positive

Answer:

9/50

Step-by-step explanation:

18% = 18/100

GCF of 18 and 100 = 2

(18 ÷ 2)/(100 ÷ 2)

9/(100 ÷ 2)

9/50

Answer:

m=0

Step-by-step explanation:

Answer:

Let's define:

G = cost of a goat

S = cost of a sheep.

We know that the total cost for a goat and a sheep is £120, then:

S + G = £120

And the cost of the goat is twice the price of the sheep, then:

G = 2*S

To solve this system, we can just replace the second equation into the first one, then we get:

S + (2*S) =  £120

3*S =  £120

S =  £120/3 =  £40

This means that each sheep costs  £40

And the cost of a goat is:

G = 2* £40 =  £80.

Now we know that he sold both of them, where:

s = price of the sheep

g = price of the goat.

We know that he sold both of them for £180, then:

s + g = £180

And the profit of the sheep is twice the profit of the goat, then:

(s - S) = 2*(g - G)

(s -  £40) = 2*(g -  £80)

s  -  £40 = 2*g -  £160

Then we have a system of equations:

s + g = £180

s  -  £40 = 2*g -  £160

To solve this, we first could isolate g in the first equation:

g = £180 - s

Replacing this in the other equation we get:

s - £40 = 2*( £180 - s) -  £160

s - £40 = £360 - 2*s - £160

s - £40 = £200 - 2*s

s + 2*s = £200 - £40 = £160

3*s = £160

s = £160/3 = £53.33

Then the percentage profit for the sheep is:

percentage profit = (s/S)*100% = (£53.33/£40)*100% = 133.3%

Then the percentae profit is 33.3%, which means that the sheep was sold at 133.3% of its original cost, leaving a profit of 33.3% of its original cost.

Answer:

Slope-Intercept: y = 10x - 82    Point Slope form: y + 2= 10(x - 8)

Step-by-step explanation:

To create a Slope-Intercept form, you need to first find the y-intercept. To do that, you need to plug in the coordinates in the eqaution so far, y = 10x +b.

y = 10x +b.

-2 = 10(8) + b

-2 = 80 + b

-82 = b

y = 10x - 82

Point Slope form: y + 2= 10(x - 8)

Answer:

about 13 cans of paint

Step-by-step explanation:

To find how many cans the farmer needs to buy, you need to know the surface area of both the cone and cylinder.  

The way to find the SA of the cone would be area = 3.14 x r^2 + 3.14 x r x sqrt(r^2 + h^2).  

SA= 1976.0617791 m^2.

The way to find SA of the cylinder under the cone would be 3.14 x d x (d / 2 + h).

A = 3097.6103564 m^2

Then you have to add 1976.0617791+3097.6103564 which gives you 5,073.8. (5,073 being total surface area of the silo)

Next divide that by 400.

5,073.8/400 = 12.7

He would need to buy about 13 cans of paint to be able to paint the entire silo.

Answer:D

Step-by-step explanation:

Answer:

10 small boxes and 12 large boxes

Step-by-step explanation:

Let x = number of large boxes

Let y = number of small boxes

We are told that;

volume of each small box = 6 cubic feet

volume of each large box = 22 cubic feet.

Total volume = 324 ft³

Thus;

6x + 22y = 324 - - - (eq 1)

We are told that 22 boxes of paper were shipped.

Thus; x + y = 22 - - - (eq 2)

Making x the subject in eq 2 gives;

x = 22 - y

Put 22 - y for x in eq 1;

6(22 - y) + 22y = 324

132 - 6y + 22y = 324

16y = 324 - 132

16y = 192

y = 192/16

y = 12

So, x = 22 - 12 = 10

Answer:

I think it's y= +10

not sure tho :))

Answer:

Step-by-step explanation:

Use Pythagorean theorem,

Base² + altitude² = hypotenuse²

15² +  altitude²  = 17²

225 +  altitude²  = 289

             altitude² = 289 - 225

             altitude² = 64

              altitude² = 8²

             altitude   = √8²

 altitude  = 8

P = 8 + 15 + 17 =  40 units

[tex]A= \frac{1}{2}*base * height\\\\ = \frac{1}{2}* 15 * 8\\\\= 15 * 4\\\\= 60 sq. units[/tex]

Answer:

60

Step-by-step explanation:

60

Answer:

65

Step-by-step explanation:

a^2 + b^2 = c^2

39^2 + 52^2 = c^2

1,521+2704 = c^2

4,225 = c^2

Find the square root of both

65 = c

Answer:

1. Shade 7 boxes in.

If 100% is 400 each 10% segment would be 40 and in order to get 70% (or 280) we shade in 7 boxes.

2. The football team scored 280 points. We get this number by multiplying .70 by 400

3. Marcy would spend more money.

To do this problem we multiply the percent by how much they have to get how much they spend.

Stephenson: 12% of 200$

.12 x 200 = 24$

Marcy: 8% of 350$

.08 x 350 = 28$
