The length of a rectangle is three times the width. A new
rectangle is created by decreasing the length of the original rectangle by 9 feet
and increasing its width by 4 feet. The area of the new rectangle is the same as
the area of the original rectangle. What is the perimeter of the new rectangle?

Answer:

7/12

Step-by-step explanation:

When you multiply fractions you just multiply across. 7*6 = 42 and 8*9 = 72. The both of these numbers can be divided by six so 42/6 = 7 as the numerator. 72/6 = 12 for the denominator. 7/12 is the answer.

Answer:

The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number.

Step-by-step explanation:

first finding the area of the triangle by Heron's formula.

s=(a+b+c)/2, a=BC=5 unit, b=AC= 4√2unit, c=AB=7unit.

s=(5+4√2+7)/2 = (12+4√2)/2 =2( 6+2√2 )/2 = 6+2√2 unit .

Now, the Heron's formula : √s(s-a)(s-b)(s-c)

> √ (6+2√2)[(6+2√2)-5][(6+2√2)-4√2][(6+2√2)-7]

we have use √2's value ; 1.414 to simplify.

please simplify it with the help of calculator or doin it in a copy, because it is very difficult to share the full calculation. AFTER CALCULATION,

> √196.0000 > 14(units)².

Now, we know that the area of triangle is 14(units)². and another formula of finding the area of triangle is ½(base)(height). let the height be h.

Area = ½(base)(height)

=>14= ½(7)h. (after cross multiplication)

=>(14×2)/7=h. (after cancellation)

=>2×2=h.

=> 4units = h.

Therefore, CM that is the height is 4units.

I have every time written units because the unit is not given or you have not posted if given in the question you will write that unit only like cm or m anything like that.

the answer for your question is D

The point lie in quadrant 3 and both x and y coordinates of the point will be negative.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

It is given that point lies to the left of the y-axis and below the x-axis

For an example of a point in quadrant 3 and left of the y axis and below the x axis would be (-3,-3).

Therefore, the values of tangent and cotangent will be positive, while the values of sin, cosine, cosecant, and secant will be negative if trigonometric values of triangles are used in quadrant 3.

The point lie in quadrant 3 and both x and y coordinates of the point will be negative.

Answer:

  21.1%

Step-by-step explanation:

Adding 402 g of salt to a solution whose volume is 130 × 100 mL will increase the concentration by (402/130)%, or about 3.09%.

When the concentration of 18% has 3.09% added to it, the concentration of the new mixture is about 21.1%.

Additional comment

We understand the units of concentration used here to be (1 g)/(100 mL) = 1%. These units are often used for a solution with a dissolved solid.

Answer:

C y > 2x/3 + 1

Step-by-step explanation:

Dashed line eliminates any equation option  with "equal to" in it

y rises 4 units as x increases 6 units between the blue points so slope is 4/6 = 2/3

y intercept is 1

Shaded blue area is above the dashed line so "greater than" rules apply

Answer:

C

Step-by-step explanation:

If y = -0.025x^2 + 4x, then

y' = -0.05x + 4

Set y' = 2:

2 = -0.05x + 4

-2 = -0.05x

40 = x

Go back to y to find the point:

y = -0.025(40)^2 + 4(40) = 120

So the point (40, 120) on y = -0.025x^2 + 4x will have tangent line with a slope of 2.
