Answer:

The probability is 1/2 or 50%

Step-by-step explanation:

P(roll less than 4) = Probability of rolling less than 4

There are 3 numbers that are less than 4.

1, 2, 3, 4, 5, 6.

There is a total of 6 sides.

So,

3/6 simplified to 1/2 or 50%

Do the information on a bag of fertilizer 5 pounds of fertilizer are needed for every two square feet of lawn how many square fe

gregori [183]

Answer:

25 lb bag of fertilizer can cover <u>10 square feet</u> of lawn.

Step-by-step explanation:

Given:

5 pounds of fertilizer cover = 2 $ft^2$ of the lawn

We need to find the 25 lb bag cover.

Solution:

Now we know that;

5 pounds of fertilizer = 2 $ft^2$ of yard.

1 lb of fertilizer = Number of $ft^2$ lawn covered by 1 lb fertilizer.

Using Unitary method we get;

Number of $ft^2$ lawn covered by 1 lb fertilizer = $\frac{2}{5}\ ft^2$

Now we can say that;

1 lb of fertilizer = $\frac{2}{5}\ ft^2$ of the yard

25 lb of fertilizer = Number of $ft^2$ lawn covered by 25 lb fertilizer.

Again by using Unitary method we get;

Number of $ft^2$ lawn covered by 25 lb fertilizer. = $\frac{2}{5}\times 25 = 10 \ ft^2$

Hence 25 lb bag of fertilizer can cover <u>10 square feet</u> of lawn.

A fireplace arch is to be constructed in the form of a semiellipse. The opening is to have a height of 3 feet at the center and

USPshnik [31]

Answer:

Step-by-step explanation:

Given

Fireplace is in the form of semi-ellipse with height of 3 ft from center

Length of base=8 ft

if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis

2 a =8

a=4 ft

If contractor cover the whole base

then total length of string=2a =8 ft

(b)String should be nailed at focus

focus of ellipse is a e

where e=eccentricity

$e=\sqrt{1-(\frac{b}{a})^2}$

$e=\sqrt{1-(\frac{3}{4})^2}=\frac{\sqrt{7}}{4}$

Focus $=ae =\sqrt{7}$

Thus string should be nailed at 2.64 m from center

how many solutions does each system of equation have?? explain how you know without solving the system

Leto [7]

Answer:

no solution

Step-by-step explanation:

the x value in a linear equation in slope intercept form represents the slope of the line, since both equations int the system have the same slope there is no solution.
