Answer:

10 cm x 15 cm i think

Step-by-step explanation:

Answer:

Area = 1/2 bh

Step-by-step explanation:

10 x 15 = 150/2 which is 75

Answer:

42

Step-by-step explanation:

Given that:

Sample space = {1, 2, 3, 4, 5,6}

Probability of obtaining an odd number in a single roll :

Probability = required outcome / Total possible outcomes

Required outcome = {1,3,5} = 3

Total possible outcomes = 6

P(odd number) = 3/6 = 1/2

Number of odds on 84 die rolls :

1/2 * 84 = 42 times

Answer:

Step-by-step explanation:

b/c they end up in the same place but take different ways of getting there...  90 + 270 adds up to a full circle of 390 so b/c one goes in the positive direction and one goes in the negative, the both get to the same location, :)

Step-by-step explanation:

Answer:

y < 28

Step-by-step explanation:

get the y on its own

y/2 - 6 < 8

y/2 - 6 + 6 = y/2

8 + 6 = 14

y/2 < 14

y/2 x 2 = y

14 x 2 = 28

y < 28

Hence, the weight of each cat is [tex]68.57[/tex].

What is the division?

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.

Here given that,

A lion weighs [tex]7[/tex] times as much as a leopard. The combined weight of the cats is [tex]480[/tex] pounds.

So, the weight of each cat is [tex]\frac{480}{7}=68.57[/tex].

Hence, the weight of each cat is [tex]68.57[/tex].

Answer:

160 pieces of gum in 20 days.

Step-by-step explanation:

First we have to find the number of gum she chewed in a day. To do this divide 112 and 14. We got 8. Then multiply the number of gum she chewed in  a day (8) by the number of days (20).

8 x 20 = 160

She chewed 160 pieces of gum in 20 days.

Hope this helps!!

Have a good day!!

Answer:

11 ft

Step-by-step explanation:

The formula for the area of a rectangle of length L and width W is

A = L * W.  

Represent the length, L, by 2W + 1 ("1 more than twice the width").  Then the area formula (above) becomes:

A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:

2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}.  Let's use the quadratic formula to solve this for W:

The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441.  The square root of 441 is 21.  Thus, the quadratic formula gives us:

        -1 ± 21

W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2

            2(2)

A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.

Then, according to the formula for L that we found earlier, L  = 2W + 1, or

L = 2(5) + 1, or L = 11.

Check:  Does L * W result in an area of 55 ft²?  Yes

The length dimension of the rectangle is 11 ft

Answer:

13/4

Step-by-step explanation:

To find the slope we use the equation

m= (y2-y1)/(x2-x1)

   = (85-20)/(20-0)

    = 65/20

    = 13/4

Answer:

1.y=3x-7

2.y=-3x-5

3.y=x+2

4.y=-4x+1

5.y=x+6

6.y=1/2x+5

Step-by-step explanation:

parallel lines have the same slope

1.y-2=3(x-3)

y-2=3x-9

y=3x-9+2

y=3x-7

2.y-(-2)=-3(x-(-1))

y+2=-3x-3

y=-3x-3-2

y=-3x-5

3.y-1=1(x-(-1)

 y-1=1(x+1)

 y-1=1x+1

y=1x+1+1

y=1x+2

4,y-(-3)=-4(x-1)

y+3=-4x+4

y=-4x+4-3

y=-4x+1

5.y-2=1(x-(-4)

 y-2=1(x+4)

y-2=1x+4

y=1x+4+2

y=1x+6

6.y-3=1/2(x-(-4)

 y-3=1/2(x+4)

 y-3=1/2x+4/2  simplify 4/2 to 2/1 =2

 y=1/2x+2+3

 y=1/2x+5

Answer:

g(n) = 18 - 4n

Step-by-step explanation:

Given the recursive formula

g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14

The explicit formula for an arithmetic sequence is

g(n) = g(1) + (n - 1)d , then

g(n) = 14 - 4(n - 1)

       = 14 - 4n + 4

       = 18 - 4n

Answer:

34.72 feets

Step-by-step explanation:

Using the relation :

Length of tree / shadow of tree = height of melody / shadow of melody

From the details given in the question :

Let height of tree = h

h / 62 = 5.6 / 10

Cross multiply

h * 10 = 62 * 5.6

h = 347.2 / 10

h = 34.72 feets

Hence, the height of tree is 34.72 feets
