Answer:

252 cm²

Step-by-step explanation:

Area of a rectangle is width times length:

A = WL

If the width and length increase by a factor of 1.5:

A = (1.5 W) (1.5 L)

A = 2.25 WL

So the area increases by a factor of 2.25.

2.25 × 112 cm² = 252 cm²

Answer:

The answer is 9/11.

Step-by-step explanation:

To find the answer you'd first add up how many patients you have:

80+10+20 = 110.

Now find out that how many patients are taking a real drug, which is represented by 80+10 = 90.

So, the probability of a patient NOT getting a placebo is 90/110

Simplified would be 9/11

Thus the answer is 9/11....

Answer:

9

Step-by-step explanation:

The coefficient is the number directly next to the variable, in this case, the variable being y, and the number being 9.

In the question:

9y + 5,

9 is the coefficient

y is the variable

5 is a constant (does not change).

Note that the coefficient and constant cannot change, but the value of the variable (y) can vary (hence the name).

~

The coefficient in the expression is 9.

The coefficient of a term in an algebraic expression is the number that is multiplied by the variable in the term.

To find the coefficient of a term, you can follow these steps:

1. Identify the variable in the term.

2. Look for the number that is multiplied by the variable.

3. That number is the coefficient of the term.

In the expression 5+ 9y, the variable is y. The number that is multiplied by y is 9.

Therefore, the coefficient in the expression is 9.

Answer: A) x=-8±5[tex]\sqrt{2}[/tex]

Step-by-step explanation: to find the solutions of the given equation, we need to use the substitution u=x+2, so the equation would now be:

[tex]u^{2} +12u-14=0[/tex]

the quadratic formula is:

u=(-b±[tex]\sqrt{b^{2}-4ac }[/tex])/2a

in this case a=1;  b=12;  and c=-14

so replacing the values it remains:

u=(-12±[tex]\sqrt{12^{2}-4*1*(-14) }[/tex])/2*1

u=(-12±[tex]\sqrt{144+56}[/tex])/2

u=(-12±[tex]\sqrt{200}[/tex])/2              

we can write 200 as 100*2 and the square root of 100 is 10:

The length of the hypotenuse of a right triangle formed inside the unit circle with a radius of 1 is simply 1.

The expression equal to the length of the hypotenuse of a right triangle formed inside the unit circle, with a radius of 1, can be found using the Pythagorean theorem. In a unit circle, the hypotenuse of any right triangle formed by a radius will always have a length of 1, because the radius of a unit circle is 1 by definition. So, the expression you are looking for is simply 1, since the hypotenuse in this case is the radius of the circle.

It is -1, you first make the -1 positive but then the negative sign outside makes that 1 turn -1

Plot the point, and the finished graph should look like Fig. 3.

Answer:

(2, 4)

Step-by-step explanation:

Both equations have been solved for y, so to find x we need only set the equations = to each other:    y=-x+6   =  y=3x-2

Combining like terms, we get 4x = 8, and x = 2.  Substituting 2 for x in y = 3x -2, we get y = 3(2) - 2 = 4.

The solution is (2, 4).  If you were to graph these two lines, you'd find that they intersect at (2, 4).

Step-by-step explanation:

By definition the cosine of an angle is the quotient between the side adjacent to the angle and the hypotenuse.

In other words:

[tex]cos (A) = \frac{adjacent}{hypotenuse}[/tex]

In this triangle the length of the side adjacent to the angle A is 30, and the length of the hypotenuse is 50

So:

[tex]cos(A) = \frac{30}{50}[/tex]

Simplifying we have that:

[tex]cos(A) = \frac{3}{5}=0.6[/tex]

Answer:

Final answer is [tex]\cos\left(A\right)=\frac{3}{5}[/tex].

Step-by-step explanation:

Using given information in the picture, we need ot find the missing value of Cos(A).

Apply formula of cosine function which is :

[tex]\cos\left(A\right)=\frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos\left(A\right)=\frac{30}{50}[/tex]

[tex]\cos\left(A\right)=\frac{3}{5}[/tex]

Hence final answer is [tex]\cos\left(A\right)=\frac{3}{5}[/tex].

The correct answers are:

A. P = 58 and Q = 78

C. P = -78 and Q = -52

D. P = 58 and Q = -78

To determine which values of P and Q result in the equation Px + 52 = Qx - 78 having exactly one solution, we need to ensure that the coefficients of x on both sides are not equal. This means P should not be equal to Q.

The given equation is:

Px + 52 = Qx - 78

First, let's rearrange the terms to isolate x:

Px - Qx = -78 - 52

(P - Q)x = -130

For this equation to have exactly one solution, P - Q must be non-zero. Therefore, P - Q.

Let's evaluate each option:

A. P = 58 and Q = 78

- P - Q = 58 - 78 = -20

- Since -20 is not zero, this pair results in exactly one solution.

B. P = 52 and Q = 52

- P - Q = 52 - 52 = 0

- Since 0 is zero, this pair does not result in exactly one solution.

C. P = -78 and Q = -52

- P - Q = -78 - (-52) = -78 + 52 = -26

- Since -26 is not zero, this pair results in exactly one solution.

D. P = 58 and Q = -78

- P - Q = 58 - (-78) = 58 + 78 = 136

- Since 136 is not zero, this pair results in exactly one solution.

Answer:

To have an infinite number of solutions, the equations must graph the same line. That means the equations must be equivalent. To form an equivalent equation, use the properties of equality to rewrite the given equation in a different form. Add, subtract, multiply, or divide both sides of the equation by the same amount.

A system of two linear equations in two variables has an infinite number of solutions if the slope and y-intercept of the two lines is same.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line. If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that the equation is,

y = 2/3 x - 5

If the slope and y-intercept of the two lines are the same, a system of two linear equations in two variables has an infinite number of solutions.

The equations must graph the same line if there are infinitely many solutions. Therefore, the equations must be equal. The above equation may be rewritten in a different way using the equality principles to create an equivalent equation. Both sides of the equation should be increased, decreased, multiplied, or divided by the same quantity.

Thus, system of two linear equations in two variables has an infinite number of solutions if the slope and y-intercept of the two lines is same.

12+8=20

Final answer:

The ratio of 12 brown tiles to 20 total tiles is 3:5, indicating that for every 3 brown tiles, there are 5 total tiles in that section.

Explanation:

To compare the number of brown tiles to the total number of tiles in one section, use the ratio:

12 brown tiles : 20 total tiles = 12 : 20 = 3 : 5

This ratio simplifies to 3:5, showing that for every 3 brown tiles, there are 5 total tiles in that section. The ratio of 12 brown tiles to 20 total tiles is 3:5, indicating that for every 3 brown tiles, there are 5 total tiles in that section.

Answer:

The second one.

Step-by-step explanation:

The slope of the graph, -1/3, is going down from left to right because it is negative, so it is decreasing. Slope is the rise over run, so because the slope is -1/3 look for lines that go down 1 unit and across 3 at the same time (from one corner of a square to the other). Then, because your y-intercept is a 5, just look for your line to cross the y-axis at 5. And that's it.

The second graph is the graph of the linear equation y = - 1/3x + 5.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The given linear equation is  y = - 1/3x + 5

We need to select the graph of the equation.

The slope of the line is -1/3

y intercept is 5.

Let us find few points to determine the graph.

if x=0, then y=-1/3(0)+5=5

So (0, 5) is one of the point

if x=1, then y=-1/3(1)+5

=14/3

(1, 14/3)

if x=2, then y=-1/3(2)+5

=13/3

(2, 13/3)

if x=3, then y=-1/3(3)+5

(3, 4) is point.

Now let us check these points which satisfy the graph.

Hence, the second graph is the graph of the linear equation y = - 1/3x + 5.
