Answer: true

Step-by-step explanation:

A system of linear equations can be written as:

y = a*x + c

y = d*x + f

Now, the idea of this is find the point (x, y) where both linear equations meet.

Particularlly, if the slope in both equations is the same, we will have two options:

1) The lines are parallel, so they never met, and the system has no solution.

2) The lines are the same lines (this happens when c = f) and this means that we have infinite solutions.

So it is true, if the slopes are the same, the linear system is not consisten.

Answer:

V = 54316.7 in³

Step-by-step explanation:

V = 54316.7463 in³

The solution is, the volume of a hemisphere with a radius of 29.6 in, rounded to the nearest tenth of a cubic inch is, 54289.2 cubic inches.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

a hemisphere with a radius of 29.6 in,

i.e. The radius is 29.6.

now, we know that,

the volume of a hemisphere = 2/3 * pi* r^3

using the formula, we get,

V = 2/3 * 3.14 * 29.6³

   =54289.2100267

now, rounded to the nearest tenth  we get,

54289.2100267 ≈ 54289.2

The volume of the hemisphere should be 54289.2 cubic inches.

Answer:

30 percent

Step-by-step explanation:

12/40=0.3

0.3=30 percent

Answer:

30%

Step-by-step explanation:

To find a percent, use this equation:

x/100 = n/t

where x is the percent, n is the select number of things, and t is the total number of things

Substitute:

x/100 = n/t

x/100 = number of shots Marin made/number of shots attempted

x/100 = 12/40

Now, we need to cross multiply, or multiply the numerators by the denominators of the other fraction, and vice versa.

Multiply:

x/100 = 12/40

x(40) = 40x

100(12) = 1200

40x = 1200

Now, divide both sides of the equation to find the value of x.

Divide:

40x = 1200

/40     /40

x = 30

Now we have the percent is fraction form: 30/100

To make it a percentage, simply take the numerator and add the % sign.

Therefore, Martin made 30% of his shots.

Answer:

let w = amt of water required

:

An equation based on the the percent water, an 80% solution is 20% water.

.20(320-w) + w = .50(320)

64 - .2w + w = 160

.8w = 160 - 64

w = 96%2F.8

w = 120 gal of water to produce 320 gal of 50% antifreeze

:

320 - 120 = 200 gal of 80% solution

Water: _120___ gallons

Premium Antifreeze: __200___ gallons

Answer:

81 m².

Step-by-step explanation:

To find the area of a square, you will simply need to do the side-length squared, or [tex]A= l^{2}[/tex].

If the side-length is 9, we can do:

A = 9²

A = 81 m²

Step-by-step explanation:

Step 1:  Find the area

An area of a square has a formula of → [tex]A= s^2[/tex]

[tex]A = 9 * 9[/tex]

[tex]A = 81[/tex]

Answer:sorry mabye if you elpan it mire i can help

Step-by-step explanation:

The equations used to solve this problem is I = (4500)(0.052)(2.5).

The correct option is (C).

Simple interest is a loan interest payment that borrowers pay to lenders. It is based solely on the principal and does not account for compounding interest. Straightforward interest is not limited to certain loans. It is also the form of interest that banks pay on savings accounts.

Given:

P = $4500

R= 5.2%

Time= 2 and half year

Using the formula of Simple Interest

= P x R x T / 100

= (4500 x 5.2 x 2.5)/ 100

= (4500 x 0.052 x 2.5)

= $585

So, the equation is: : I = (4500)(0.052)(2.5)
